Suppose y varies inversely with x. Write an equation if y=40 when x=16

Answers

Answer 1
y = 40 when x = 16, so 40 = k/16

Therefore, k = 640

So, y = 640/x

[tex]-\frac{11}{12}[/tex]

Step-by-step explanation:

[tex]\frac{5}{8} +\frac{3}{4} =\frac{11}{8} \\\\\frac{11}{8}=1.375\\\\\frac{-2}{3} -\frac{5}{6} =-\frac{3}{2} \\\\-\frac{3}{2}=-1.5\\\\\frac{1.375}{-1.5} =-\frac{11}{12}[/tex]

We'll split this up between the numerator and denominator.

Numerator:

5/8 + 3/4

Step 1) Make all of the denominators the same

5/8 + 6/8

Step 2) Add the numerators together

11/8

Denominator:

-2/3 - 5/6

Step 1) Make all of the denominators the same

-4/6 - 5/6

Step 2) Subtract the numerators

-9/6

Now we have (11/8) / (-9/6). Dividing fractions is the same as multiplying by the reciprocal.

11/8 x -9/6

-99/48

-2 3/48

-2 1/16

Answer:

A. x=1, y=3

Step-by-step explanation:

you have to isolate y in the bottom equation in order to put it into the top equation. heres what i did:

we will start with the bottom equation, x+y=4. then, subtract x on both sides of the equation. this will isolate y. now, we have the equation; y=4-x.

next, we are going to substitute our new bottom equation in where y is on the top. it looks like this: 2x+(4-x)=5. then, we are going to get rid of the parenthesis, so our equation is: 2x+4-x=5. to solve this, we have to combine like terms, so we will combine the x terms: x+4=5. now, isolate the variable. to do this, we have to take away 4 from each side so we can get x alone: x=1.

so now that we have a value for x, we can use that to find y. we can actually substitute our x-value into the bottom equation to make it easier: 1+y=4. next, we have to isolate the variable, which is y. this gives us the final answer: y=3.

Save and Fxit

Answers

25 years had temperatures within one standard deviation of the mean.

What is standard Deviation?

The term "standard deviation"  (or σ) refers to a measurement of the data's dispersion from the mean. A low standard deviation implies that the data are grouped around the mean, whereas a large standard deviation shows that the data are more dispersed.

Given:

Data for the average daily temperature on January 1 from 1900 to 1934 for city A.

Mean u = 24°C

standard deviation σ = 4°C

Now, Interval for 1 standard deviation ( σ ):                                    

[ u - σ , u + σ ]

[ 24 - 4 , 24 + 4 ]

[ 20 , 28 ] °C

Now, determine the number of years the temperature T lied in the above calculated range: [ 20 , 28 ].

T1 = 20 , n1 = 2 years

T2 = 21 , n2 = 3 years  

T3 = 22 , n3 = 2 years

T4 = 23 , n4 = 4 years  

T5 = 24 , n5 = 3 years

T6 = 25 , n6 = 3 years  

T7 = 26 , n7 = 5 years

T8 = 27 , n8 = 2 years

T5 = 28 , n9 = 1 years

and, The total number of years:

∑ni = n1 + n2 + n3 + n4 + n5 + n6 + n7 + n8 + n9

=  2 + 3 + 2 + 4 + 3 + 3 + 5 + 2 + 1

Answer:

A polynomial is a combination of terms separated by + or - signs. A polynomial does not contain variables raised to negative or fractional exponents, variables in the denominator or under a radical, or any special features such as trigonometric functions, or logarithms.

Final answer:

The expression 7r - 6r^3 - 10r^4 is a polynomial because it consists of terms with variables raised to non-negative integer exponents.

Explanation:

The expression 7r - 6r3 - 10r4 is a polynomial because it is a mathematical expression consisting of terms with variables raised to non-negative integer exponents.

A polynomial is an algebraic expression made up of one or more terms, where each term has a coefficient and a variable raised to a non-negative integer exponent. In this case, the expression has three terms: 7r, -6r3, and -10r4. The variable in the expression is 'r', and each term is raised to a non-negative integer exponent.

Answers

Answer:

Therefore Joe is taller than the height of the tepee.

Step-by-step explanation:

Cone:

Cone is three dimensional shape. It has an vertex.Slant height of an object is a height that measured along a lateral surface from the vertex to the the base. The slant height of a cone is =   [tex]\sqrt{height^2+radius^2}[/tex]The height of a cone is  [tex]=\sqrt{slant\ height ^2- radius^2[/tex]The volume of a cone =  [tex]\frac{1}3 \pi r^2 h[/tex]Lateral surface area is  [tex]=\pi r l[/tex]

Given that,

A cone shaped tepee has a radius of 4 feet and slant height of 7 feet.

The height of the cone is  [tex]=\sqrt{slant\ height ^2- radius^2[/tex]

Which polynomial has zeros of 2, 5, and -4?

A. (x + 2)(x + 5)(x - 4)
B. (2x - 4)(x + 5)(x + 4)
c. 6 - 2)(x - 5)(x - 4)
D. (2x - 4)(x - 5)(x + 4)

Answers

The polynomial has zeros of 2, 5, and -4 is option (d) (2x - 4)(x - 5)(x + 4).

What is polynomial?

A polynomial is a mathematical equation made up of indeterminates and coefficients and uses only addition, subtraction, multiplication, and non-negative integer exponentiation of variables.

How to find the correct polynomial?

To find a polynomial that has zeros 2, 5, and -4 substituted x = 2, 5, and -4 in a polynomial.

By substituted x = 2, 5, and -4 in a polynomial (2x - 4)(x - 5)(x + 4).

(a) For x=2.

The polynomial is

(2(2) - 4)(2- 5)(2 + 4) = (4- 4)(-3)(6)

                                 = 0×-3×6

                                 = 0

(b) For x=5.

The polynomial is

(2(5) - 4)(5 - 5)(5 + 4) = (10-4)(0)(9)

                                  = 6×0×9

                                  = 0

(c) For x=-4.

The polynomial is

(2(-4) - 4)(-4 - 5)(-4 + 4) = (-8-4)(-9)(0)

                                  = -`12×-9×0

                                  = 0

Since (2x - 4)(x + 5)(x + 4) has zeros of 2, 5, and -4

For incorrect options

By substituted x = 2, 5, and -4 in a polynomial  (x + 2)(x + 5)(x - 4), (2x - 4)(x + 5)(x + 4) and (6x - 2)(x - 5)(x - 4) is not equal to zero therefore (a), (b) and (c)is not correct option.

Final answer:

The correct polynomial with zeros of 2, 5, and -4 is represented by Option C, which is (x - 2)(x - 5)(x + 4), even though there is a typo in the option provided.

Explanation:

The zeros of a polynomial are the values for which the polynomial evaluates to zero. These are also the solutions to the equation obtained by setting the polynomial equal to zero. Given the zeros of 2, 5, and -4, we can form a polynomial by finding the factors associated with each zero and then multiplying those factors together.

The factor associated with the zero 2 is (x - 2), the factor for the zero 5 is (x - 5), and the factor for the zero -4 is (x + 4). Multiplying these factors will give us the polynomial that has these zeros:

P(x) = (x - 2)(x - 5)(x + 4).

Comparing this expression with the options provided:

Option A is incorrect because it has factors of (x + 2) and (x - 4), implying zeros of -2 and 4.Option B is incorrect because it has the factor of (2x - 4), which simplifies to (x - 2), but includes the incorrect (x + 4).Option C is correctly formed with (x - 2)(x - 5)(x + 4), despite the typo, and represents the polynomial with the given zeros.Option D is incorrect, similar to option B.

Therefore, the correct answer is Option C, which is (x - 2)(x - 5)(x + 4).

Emily purchased a couch, loveseat, in the chair for $2000. The Loveseat cost twice as much as the chair, and the couch cost $600 more than the love seat. Find the cost of the couch, loveseat, and chair.

Answers

Answer:

Chair $280

Loveseat $560

Couch $ 1,160

Step-by-step explanation:

chair = x

loveseat=2x

couch = 2x + 600

x +2x + 2x +600 = 2000

5x + 600 =2000 subtract 600 from both sides

5x =1400 divide by 5

x = $280

Chair is the value of x =$280

Loveseat is twice the value of x = 2 x $280 =$560

Couch is twice the value of x plus $600 = $560 + $600

The cost of a chair, the cost of a loveseat, and the cost of a couch are $280, $560, and $1,160 respectively.

What is the linear system?

It is a system of an equation in which the highest power of the variable is always 1. A one-dimension figure that has no width. It is a combination of infinite points side by side.

Given

Emily purchased a couch, loveseat, in the chair for $2000.

The Loveseat cost twice as much as the chair, and the couch cost $600 more than the love seat.

Let

The cost of the chair is x, then the loveseat is 2x and the cost of the couch is 2x + 600.

Then

The sum of the cost of the chair, loveseat, and couch is $2000.

[tex]x + 2x + 2x + 600 = 2000\\[/tex]

On simplifying, we have

x = 280

Then

The cost of the chair = x = $280.

The loveseat = 2x = 2(280) = $560

The cost of the couch = 2x + 600 = 2(280) + 600 = $1,160

Thus, the cost of the chair, loveseat, and couch is $280, $560, and $1,160 respectively.
