Answers

Answer 1

Answer:

Ratio: 20:36

Rate: 20 squids per 36 eels

Simplified ratio:

[tex] = \frac{20}{36 } = \frac{10}{18} = \frac{5}{9} [/tex]

Unit ratio:

20/36 squids per eel (dividing by 36)

Please mark Brainliest if this helps!

Answer 2

Answer:

Step-by-step explanation:

Number of squid in the tank = [tex]20[/tex]

Number of eels in the tank = [tex]36[/tex]

Rate of squids to eels will be obtained by creating a fraction of number of squids over number of eels

Rate of squid to eels = [tex]\frac{20}{36}[/tex]

also ratio of squid to eels will be written as [tex]20:36[/tex]

Simplified ratio = [tex]\frac{20}{36} = \frac{5}{9} = 5:9[/tex]

Unit rate will be defined as number of squid per eels

Unit rate = [tex]\frac{20}{36} = 0.55[/tex]

What is the slope of st.line xcosa+ysina=p? ( Find by using derivative)​

Answers

Answer:

Assume that [tex]a[/tex] and [tex]p[/tex] are constants. The slope of the line will be equal to

[tex]\displaystyle -\frac{\cos{(a)}}{\sin{(a)}} = \cot{(a)}[/tex] if [tex]\sin{a} \ne 0[/tex];Infinity if [tex]\sin{a} = 0[/tex].

Step-by-step explanation:

Rewrite the expression of the line to express [tex]y[/tex] in terms of [tex]x[/tex] and the constants.

Substract [tex]x\cdot \cos{(a)}[/tex] from both sides of the equation:

[tex]y \sin{(a)} = p - x\cos{(a)}[/tex].

In case [tex]\sin{a} \ne 0[/tex], divide both sides with [tex]\sin{a}[/tex]:

[tex]\displaystyle y = - \frac{\cos{(a)}}{\sin{(a)}}\cdot x+ \frac{p}{\sin{(a)}}[/tex].

Take the first derivative of both sides with respect to [tex]x[/tex]. [tex]\frac{p}{\sin{(a)}}[/tex] is a constant, so its first derivative will be zero.

[tex]\displaystyle \frac{dy}{dx} = - \frac{\cos{(a)}}{\sin{(a)}}[/tex].

[tex]\displaystyle \frac{dy}{dx}[/tex] is the slope of this line. The slope of this line is therefore

[tex]\displaystyle - \frac{\cos{(a)}}{\sin{(a)}} = -\cot{(a)}[/tex].

In case [tex]\sin{a} = 0[/tex], the equation of this line becomes:

[tex]y \sin{(a)} = p - x\cos{(a)}[/tex].

[tex]x\cos{(a)} = p[/tex].

[tex]\displaystyle x = \frac{p}{\cos{(a)}}[/tex],

which is the equation of a vertical line that goes through the point [tex]\displaystyle \left(0, \frac{p}{\cos{(a)}}\right)[/tex]. The slope of this line will be infinity.

one x-intercept for a parabola is at the point (2, 0). use the quadratic formula to find the other x-intercept for the parabola defined by y=x^2-3x+2​

Answers

Answer:

Step-by-step explanation:

There are 3 ways to find the other x intercept.

1) Polynomial Long Division.

Divide x^2 - 3x + 2 by the binomial x - 2, because by the Factor Theorem if a is a root of a polynomial then x - a is a factor of said polynomial.

2) Just solving for x when y = 0, by using the quadratic formula.

[tex]x^2 - 3x + 2 = 0\\x_{12} = \frac{3 \pm \sqrt{9 - 4(1)(2)}}{2} = \frac{3 \pm 1}{2} = 2, 1[/tex].

So the other x - intercept is at (1, 0)

3) Using Vietta's Theorem regarding the solutions of a quadratic

Namely, the sum of the solutions of a quadratic equation is equal to the quotient between the negative coefficient of the linear term divided by the coefficient of the quadratic term.

[tex]x_1 + x_2 = \frac{-b}{a}[/tex]

And the product between the solutions of a quadratic equation is just the quotient between the constant term and the coefficient of the quadratic term.

[tex]x_1 \cdot x_2 = \frac{c}{a}[/tex]

These relations between the solutions give us a brief idea of what the solutions should be like.

how to divide (x^2+5x-6)/(x-1)

Answers

Answer:

x+6

Step-by-step explanation:

Let's see if the numerator is factorable.

Since the coefficient of x^2 is 1 (a=1), all you have to do is find two numbers that multiply to be -6  (c) and add up to be 5 (b).

Those numbers are 6 and -1.

So the factored form of the numerator is (x+6)(x-1)

So when you divide (x+6)(x-1) by (x-1) you get (x+6) because (x-1)/(x-1)=1 for number x except x=1 (since that would lead to division by 0).

Anyways, this is what I'm saying:

the number of three-digit numbers with distinct digits that be formed using the digits 1,2,3,5,8 and 9 is . The probability that both the first digit and the last digit of the three-digit number are even numbers .

Answers

Answer:

a)120

b)6.67%

Step-by-step explanation:

Given:

No. of digits given= 6

Digits given= 1,2,3,5,8,9

Number to be formed should be 3-digits, as we have to choose 3 digits from given 6-digits so the no. of combinations will be

6P3= 6!/3!

      = 6*5*4*3*2*1/3*2*1

      =6*5*4

      =120

Now finding the probability that both the first digit and the last digit of the three-digit number are even numbers:

As the first and last digits can only be even

then the form of number can be

a)2n8 or

b)8n2

where n can be 1,3,5 or 9

4*2=8

so there can be 8 three-digit numbers with both the first digit and the last digit even numbers

And probability = 8/120

                          = 0.0667

                          =6.67%

The probability that both the first digit and the last digit of the three-digit number are even numbers is 6.67% !

A jet plane travels 2 times the speed of a commercial airplane. The distance between Vancouver

and Regina is 1730 km. If the flight from Vancouver to Regina on a commercial airplane takes

140 minutes longer than a jet plane, what is the time of a commercial plane ride of this route? (please show steps:))

Answers

Answer:

The time of a commercial airplane is 280 minutes

Step-by-step explanation:

Let

x -----> the speed of a commercial airplane

y ----> the speed of a jet plane

t -----> the time that a jet airplane takes  from Vancouver to Regina

we know that

The speed is equal to divide the distance by the time

y=2x ----> equation A

The speed of a commercial airplane is equal to

x=1,730/(t+140) ----> equation B

The speed of a jet airplane is equal to

y=1,730/t -----> equation C

substitute equation B and equation C in equation A

1,730/t=2(1,730/(t+140))

Solve for t

1/t=(2/(t+140))

t+140=2t

2t-t=140

t=140 minutes

The time of a commercial airplane is

t+140=140+140=280 minutes

Find the area of quadrilateral ABCD. [Hint: the diagonal divides the quadrilateral into two triangles.]
A. 26.47 units²
B. 28.53 units²
C. 27.28 units²
D. 33.08 units²

Answers

Answer:

B) 28.53 unit²

Step-by-step explanation:

The diagonal AD divides the quadrilateral in two triangles:

Triangle ABDTriangle ACD

Area of Quadrilateral will be equal to the sum of Areas of both triangles.

i.e.

Area of ABCD = Area of ABD + Area of ACD

Area of Triangle ABD:

Area of a triangle is given as:

[tex]Area = \frac{1}{2} \times base \times height[/tex]

Base = AB = 2.89

Height = AD = 8.6

Using these values, we get:

[tex]Area = \frac{1}{2} \times 2.89 \times 8.6 = 12.43[/tex]

Thus, Area of Triangle ABD is 12.43 square units

Area of Triangle ACD:

Base = AC = 4.3

Height = CD = 7.58

Using the values in formula of area, we get:

[tex]Area = \frac{1}{2} \times 4.3 \times 7.58 = 16.30[/tex]

Thus, Area of Triangle ACD is 16.30 square units

Area of Quadrilateral ABCD:

The Area of the quadrilateral will be = 12.43 + 16.30 = 28.73 units²

None of the option gives the exact answer, however, option B gives the closest most answer. So I'll go with option B) 28.53 unit²

the values of q and r.​

Answers

Answer:

m=7

Remainder =4

If q=1 then r=3 or r=-1.

If q=2 then r=3.

They are probably looking for q=1 and r=3 because the other combinations were used earlier in the problem.

Step-by-step explanation:

Let's assume the remainders left when doing P divided by (x-1) and P divided by (2x+3) is R.

By remainder theorem we have that:

P(1)=R

P(-3/2)=R

[tex]P(1)=2(1)^3+m(1)^2-5[/tex]

[tex]=2+m-5=m-3[/tex]

[tex]P(\frac{-3}{2})=2(\frac{-3}{2})^3+m(\frac{-3}{2})^2-5[/tex]

[tex]=2(\frac{-27}{8})+m(\frac{9}{4})-5[/tex]

[tex]=-\frac{27}{4}+\frac{9m}{4}-5[/tex]

[tex]=\frac{-27+9m-20}{4}[/tex]

[tex]=\frac{9m-47}{4}[/tex]

Both of these are equal to R.

[tex]m-3=R[/tex]

[tex]\frac{9m-47}{4}=R[/tex]

I'm going to substitute second R which is (9m-47)/4 in place of first R.

[tex]m-3=\frac{9m-47}{4}[/tex]

Multiply both sides by 4:

[tex]4(m-3)=9m-47[/tex]

Distribute:

[tex]4m-12=9m-47[/tex]

Subtract 4m on both sides:

[tex]-12=5m-47[/tex]

Add 47 on both sides:

[tex]-12+47=5m[/tex]

Simplify left hand side:

[tex]35=5m[/tex]

Divide both sides by 5:

[tex]\frac{35}{5}=m[/tex]

[tex]7=m[/tex]

So the value for m is 7.

[tex]P(x)=2x^3+7x^2-5[/tex]

What is the remainder when dividing P by (x-1) or (2x+3)?

Well recall that we said m-3=R which means r=m-3=7-3=4.

So the remainder is 4 when dividing P by (x-1) or (2x+3).

Now P divided by (qx+r) will also give the same remainder R=4.

So by remainder theorem we have that P(-r/q)=4.

Let's plug this in:

[tex]P(\frac{-r}{q})=2(\frac{-r}{q})^3+m(\frac{-r}{q})^2-5[/tex]

Let x=-r/q

This is equal to 4 so we have this equation:

[tex]2u^3+7u^2-5=4[/tex]

Subtract 4 on both sides:

[tex]2u^3+7u^2-9=0[/tex]

I see one obvious solution of 1.

I seen this because I see 2+7-9 is 0.

u=1 would do that.

Let's see if we can find any other real solutions.

Dividing:

1     |   2    7     0     -9

     |         2      9      9

       -----------------------

          2    9     9      0

This gives us the quadratic equation to solve:

[tex]2x^2+9x+9=0[/tex]

Compare this to [tex]ax^2+bx+c=0[/tex]

[tex]a=2[/tex]

[tex]b=9[/tex]

[tex]c=9[/tex]

Since the coefficient of [tex]x^2[/tex] is not 1, we have to find two numbers that multiply to be [tex]ac[/tex] and add up to be [tex]b[/tex].

Those numbers are 6 and 3 because [tex]6(3)=18=ac[/tex] while [tex]6+3=9=b[/tex].

So we are going to replace [tex]bx[/tex] or [tex]9x[/tex] with [tex]6x+3x[/tex] then factor by grouping:

[tex]2x^2+6x+3x+9=0[/tex]

[tex](2x^2+6x)+(3x+9)=0[/tex]

[tex]2x(x+3)+3(x+3)=0[/tex]

[tex](x+3)(2x+3)=0[/tex]

This means x+3=0 or 2x+3=0.

We need to solve both of these:

x+3=0

Subtract 3 on both sides:

x=-3

----

2x+3=0

Subtract 3 on both sides:

2x=-3

Divide both sides by 2:

x=-3/2

So the solutions to P(x)=4:

[tex]x \in \{-3,\frac{-3}{2},1\}[/tex]

If x=-3 is a solution then (x+3) is a factor that you can divide P by to get remainder 4.

If x=-3/2 is a solution then (2x+3) is a factor that you can divide P by to get remainder 4.

If x=1 is a solution then (x-1) is a factor that you can divide P by to get remainder 4.

Compare (qx+r) to (x+3); we see one possibility for (q,r)=(1,3).

Compare (qx+r) to (2x+3); we see another possibility is (q,r)=(2,3).

Compare (qx+r) to (x-1); we see another possibility is (q,r)=(1,-1).

The Montanez family is a family of four people. They have used 3,485.78 gallons of water so far this month. They cannot exceed 7,250.50 gallons per month during the drought season. Write an inequality to show how much water just one member of the family can use for the remainder of the month, assuming each family member uses the same amount of water every month.

Answers

Answer:

x ≤ 3764.72

Step-by-step expl anation:

The Montanez family cannot use more than 7250.50 gallons, this means that they can use less than or equal to 7250.50 gallons, this tells you which sign to use.  The variable x can be used to describe how much water they have left to use and then you add 3,485.78 gallons to x.

x + 3485.78 ≤ 7250.50   This inequality means that the amount of water the family has yet to use added to 3485.78 gallons cannot exceed 7250.50 gallons.

Next, you simplify the inequality using the property of inequalities.

x ≤ 7250.50 - 3485.78

x ≤ 3764.72

The required inequality is x<941.18 for the Montanez family if they have used 3485.78 gallons of water.

What is inequality?

It is also a relationship between variables but this is in greater than , less than, greater than or equal to , less than or equal to is used.

How to form an inequality?

Let the water used by a member be x

so

x*4=7250.50-3485.78

4x=3764.72

x=941.18

Hence one member can only use 941.18 gallons of water in the month.

Answer:

The correct option is A)

P(Win|Regular)=0.76

P(Win|Prevent )=0.58

You are more likely to win by playing regular defense.

Step-by-step explanation:

Consider the provided table.

We need to find which strategy is better.

If team play regular defense then they win 38 matches out of 50.

[tex]Probability=\frac{\text{Favorable outcomes}}{\text{Total number of outcomes}}[/tex]

[tex]P(Win|Regular)=0.76[/tex]

If team play prevent defense then they win 29 matches out of 50.

Thus, the probability of win is:

[tex]P(Win|Prevent )=\frac{29}{50}[/tex]

[tex]P(Win|Prevent )=0.58[/tex]

Since, 0.76 is greater than 0.58

That means the probability of winning the game by playing regular defense is more as compare to playing prevent defense.

Hence, the conclusion is: You are more likely to win by playing regular defense.

ANSWER

[tex]{(x + 10)}^{2} + {(y + 6)}^{2} = 121[/tex]

EXPLANATION

The equation of the circle in general form is given as:

[tex] {x}^{2} + {y}^{2} + 20x + 12y + 15 = 0[/tex]

To obtain the standard form, we need to complete the squares.

We rearrange the terms to obtain:

[tex] {x}^{2} + 20x + {y}^{2} + 12y = - 15 [/tex]

Add the square of half the coefficient of the linear terms to both sides to get:

[tex]{x}^{2} + 20x +100 + {y}^{2} + 12y + 36 = - 15 + 100 + 36[/tex]

PLEASE HELP!!! Given the functions, f(x) = 6x + 2 and g(x) = x - 7, perform the indicated operation. When applicable, state the domain restriction. (f/g)(x)

Answers

Final answer:

To find (f/g)(x) with f(x) = 6x + 2 and g(x) = x - 7, one must divide f(x) by g(x). The domain restriction occurs because division by zero is not defined, so we exclude the x value that makes g(x) zero, which is x = 7.

Explanation:

To perform the indicated operation (f/g)(x) with the given functions f(x) = 6x + 2 and g(x) = x - 7, we need to divide the function f(x) by the function g(x). This operation is equivalent to finding the quotient of the two functions, which is expressed as:

(f/g)(x) = f(x)/g(x) = (6x + 2)/(x - 7)

The domain restriction occurs when the denominator, g(x), is equal to zero since division by zero is undefined. So we must find the value of x for which g(x) = 0. Since g(x) = x - 7, setting this equal to zero gives us:

x - 7 = 0 → x = 7

Therefore, the domain of the function (f/g)(x) is all real numbers except for x = 7, because at x = 7 the function is undefined. The domain of (f/g)(x) can be expressed as - {7}, where represents the set of all real numbers.

Answers

The answer is C. (70).
The easiest way to explain this is to use a table. You could you other methods like by using a proportion but this way is easier.

Answer:

=70$

Step-by-step explanation:

The total in her account at day zero =85$

Lunch for five days= 3$×5

=15$

Total in her account= Initial amount - Expenditure on lunch

=85$-15$

=70$

The balance in Latesha's Lunch Account after having lunch for five day=70$

Find the values of k for which the quadratic equation 2x^2 − (k + 2)x + k = 0 has real and equal roots.

Answers

Answer:

k = 2

Step-by-step explanation:

If the roots are real and equal then the condition for the discriminant is

b² - 4ac = 0

For 2x² - (k + 2)x + k = 0 ← in standard form

with a = 2, b = - (k + 2) and c = k, then

(- (k + 2))² - (4 × 2 × k ) = 0

k² + 4k + 4 - 8k = 0

k² - 4k + 4 = 0

(k - 2)² = 0

Equate factor to zero and solve for k

(k - 2)² = 0 ⇒ k - 2 = 0 ⇒ k = 2

Answer:

k = 2

Step-by-step explanation:

A quadratic equation has two equal real roots if a discriminant is equal 0.

[tex]ax^2+bx+c=0[/tex]

Discriminant [tex]b^2-4ac[/tex]

We have the equation

[tex]2x^2-(k+2)x+k=0\to a=2,\ b=-(k+2),\ c=k[/tex]

Substitute:

[tex]b^2-4ac=\bigg(-(k+2)\bigg)^2-4(2)(k)\qquad\text{use}\ (a+b)^2=a^2+2ab+b^2\\\\=k^2+2(k)(2)+2^2-8k=k^2+4k+4-8k=k^2-4k+4\\\\b^2-4ac=0\iff k^2-4k+4=0\\\\k^2-2k-2k+4=0\\\\k(k-2)-2(k-2)=0\\\\(k-2)(k-2)=0\\\\(k-2)^2=0\iff k-2=0\qquad\text{add 2 to both sides}\\\\k=2[/tex]

B) 1.25 × 10 -14

C) 1.25 × 10 -13

D) 1.25 × 10 -12

Answers

Answer:

0.00008 ÷ 640,000,000 means

8*10^-5 ÷ 6.4*10^8

so let's collect to simplify the operation

(8÷6.4)*(10^-12) -5-7=-12

then the answer becomes 1.25×10^-14 that is B

Answer:

option C

Step-by-step explanation:

Evaluate 0.00008 ÷ 640,000,000.

0.00008 can be written in standard notation

Move the decimal point to the end

so it becomes  [tex]8 \cdot 10^{-5}[/tex]

for 640,000,000 , remove all the zeros and write it in standard form

[tex]64 \cdot 10^7[/tex]

Now we divide both

[tex]\frac{8 \cdot 10^{-5}}{64 \cdot 10^7}[/tex]

Apply exponential property

a^m divide by a^n  is a^ m-n

[tex]\frac{8}{64} =0.125[/tex]

[tex]\frac{10^{-5}}{10^7}=10^{-12}[/tex]

[tex]0.125 \cdot 10^{-12}= 1.25 \cdot 10^{-13}[/tex]

What is the equation for the hyperbola shown?

Answers

Find the answer in the attachment.

The hyperbola's equation is x² / 3600 - y² / 121 = 1, centered at the origin (0,0). Its vertices are at (60,0), (-60,0) on the x-axis, and (0,11), (0,-11) on the y-axis.

To find the equation of the hyperbola, we need to determine its center and the distances from the center to the vertices along the x and y axes. The general equation of a hyperbola centered at (h, k) is given by:

(x - h)² / a² - (y - k)² / b² = 1

Where (h, k) is the center of the hyperbola, and 'a' and 'b' are the distances from the center to the vertices along the x and y axes, respectively.

In this case, since the hyperbola is symmetric along the x and y axes, the center is at the origin (0, 0). Also, we know the distance from the center to the vertices along the x-axis is 60 units (60 and -60) and along the y-axis is 11 units (11 and -11).

So, a = 60 and b = 11.

Now we can plug these values into the equation:

x² / (60)² - y² / (11)² = 1

Simplifying further:

x² / 3600 - y² / 121 = 1

And that's the equation of the hyperbola.
