Answer:

½ = x

Step-by-step explanation:

As discussed in one of my You-Tube videos on Exponential Rules, aᵐ\ⁿ, any base to the half power is the SAME AS taking the exponential denominator of that power, and setting that to the square root of the base, leaving the exponential numerator on the outside:

25¹\² = √25

25 = a [Base]

1 = m [Exponential Numerator]

2 = n [Exponential Denominator]

As you can see, it is unnecessary to put the two because by definition, any vacant root is automatically assumed as the square root, and 1, which is the exponential numerator, is on the outside, which again is unnecessary because 5¹ is 5.

When the polynomial in P(x) is divided by (x + a), the remainder equals P(a)

Answers

Answer:

This is a false statement:

Step-by-step explanation:

According to Remainder Theorem dividing the polynomial by some linear factor x + a, where a is just some number. As a result of the long polynomial division, you end up with some polynomial answer q(x) (the "q" standing for "the quotient polynomial") and some polynomial remainder r(x).

P(x)= (x+/-a) q(x)+r(x)

P(x)=(x+a) q(x)+r(x). Note that for x=-a

P(-a)=(-a+a) q(-a)+r(-a)= 0* q(-a)+ r(-a)

P(-a)=r(-a)

It means that P(-a) is the remainder not P(a)

Thus the given statement is false....

cos155° = _____ -cos25° cos 55° cos(-25)°

Answers

Answer:

- cos 25°

Step-by-step explanation:

Cosine function is one of the trigonometric functions. Cosine function is regarded as an even function, which means that f(-x) = f(x). Also, cosine function is positive in the first quadrant and the last quadrant and negative in the second quadrant and the third quadrant. 155° lies in the second quadrant since 155° is smaller than 180°. Therefore, the basic angle or the reference angle of 155° is 180° - 155° = 25°. We know that cos 155° will be negative because it lies in the second quadrant and cos 25° will be positive because it lies in the first quadrant. Since cos 55° is positive, and cos (-25°) = cos 25° by the even function property, therefore option 2 and option 3 are incorrect since cos 155° is negative. Therefore, option 1 is the correct answer i.e. cos 155° = - cos 25°!!!

When it is 6:00 a.m. in Honolulu, it is 3:00 p.m. in London. Just before Paul’s flight from Honolulu to London, he called his friend Nigel, who lives in London, asking what kind of clothing to bring. Nigel explained that London was in the middle of some truly peculiar weather. The temperature was currently 30°C, and was dropping steadily at a rate of 1°C per hour. Paul’s flight left Honolulu at 2:00 p.m. Thursday, Honolulu time, and got into London at 12:00 p.m. Friday, London time. What kind of clothing would have been appropriate for Paul to be wearing when he got off the plane? a. shorts and sandals, appropriate for around 90-105°F b. winter wear, appropriate for around 20-45°F c. street clothes, appropriate for around 70-85°F d. a light jacket, appropriate for around 50-65°F

Answers

Answer:

b. winter wear, appropriate for around 20-45°F c.

Step-by-step explanation:

Answer:

b. winter wear, appropriate for around 20-45°F

Step-by-step explanation:

When it is 6:00 hours in Honolulu, it is 15:00 hours in London, this means that there are 15 - 6 = 9 hours of difference.

Paul got into London at 12:00 p.m, that is, at 12 - 9 = 3:00 p.m. Friday Honolulu time. Paul’s flight left Honolulu at 2:00 p.m. Thursday, so he spent 25 hours flighting.

When the flight started, the temperature in London was 30 °C, after 25 hours the temperature dropped 25 °C, so it was 30 - 25 = 5 °C.

To convert from °C to °F, we use the following formula:

(x °C × 9/5) + 32 = y °F

Replacing with x = 5

(5 °C × 9/5) + 32 = 41 °F

Which equation represents the line that passes through (–6, 7) and (–3, 6)?

y = –x + 9
y = –x + 5
y = –3x – 11y
y = –3x + 25

Answers

Answer:

The equation that represents the line that passes through (-6,7) and (-3,6) is: y = -1/3x + 5

Step-by-step explanation:

The equation of line for point=slope form is

y-y₁ = m(x-x₁)

Finding Slope m:

m= y₂-y₁/x₂-x₁

here y₂= 6,y₁= 7,x₂= -3,x₁= -6

m = 6-7/-3-(-6)

m = -1/-3+6

m = -1/3

The slope m = -1/3 and considering point (-6,7) the equation is:

y-y₁ = m(x-x₁)

y-7 = (-1/3)(x-(-6))

y-7 = -1/3(x+6)

y-7 = -1/3x -2

y = -1/3x-2+7

y = -1/3x + 5

So, the equation that represents the line that passes through (-6,7) and (-3,6) is: y = -1/3x + 5

Find the coordinates of P so that P partitions the segment AB in the ratio 1:1 if
A(13,1) and B(−5,−3)?
.

Answers

Answer:

P(4, - 1 )

Step-by-step explanation:

The ratio 1 : 1 represents the midpoint of segment AB

Using the midpoint formula

[ 0.5(x₁ + x₂ ), 0.5(y₁ + y₂ ) ]

with (x₁, y₁ ) = (13, 1) and (x₂, y₂ ) = (- 5, - 3), so

P = [0.5(13 - 5), 0.5(1 - 3) ] = [0.5(8), 0.5(- 2) ] = (4, - 1 )

the midpoint P has the coordinates (4, −1).

To find the coordinates of point P that partitions segment AB in a 1:1 ratio, also known as the midpoint, we use the midpoint formula. Given the coordinates A(13,1) and B(−5,−3), the midpoint formula is ((x1 + x2)/2, (y1 + y2)/2).

Applying the values from A and B:

For x-coordinate: (13 − 5) / 2 = 8 / 2 = 4For y-coordinate: (1 − 3) / 2 = −2 / 2 = −1

Therefore, the midpoint P has the coordinates (4, −1).

Scientists released 10 birds into a new habitat in year 0. Each year, there were
three times as many birds as the year before. How many birds were there
after x years? Write a function to represent this scenario.

Answers

Final answer:

To model the bird population that triples each year starting with 10 birds, an exponential growth function is used: f(x) = 10 × 3^x, where x is the number of years.

Explanation:

To create a function that represents the scenario of birds increasing threefold each year, we need to use an exponential growth model.

The initial population of birds is 10 and then it triples every year.

Therefore, the function that describes the number of birds after x years would be:

f(x) = 10 × 3^x

Here, f(x) represents the number of birds after x years, 10 is the initial number of birds released into the habitat, and 3^x indicates that the population is growing three times each year for x years.

Final answer:

The number of birds after x years can be calculated using the exponential function B(x) = 10 × 3^x, representing the initial population of 10 birds tripling every year.

Explanation:

The scenario describes a population of birds in a new habitat growing exponentially each year. The initial population of birds is 10 (in year 0), and the population triples every year thereafter. To represent this situation mathematically, we can use an exponential function.

To find the number of birds after x years, we can use the following function:

B(x) = 10 × 3^x

Where:

B(x) is the number of birds after x years

10 is the initial number of birds

3 is the growth factor, as the population is tripling each year

x is the number of years since the birds were first released into the habitat

This equation models exponential growth and gives us the predicted population of the birds for any given year x.

Len needs $135.75 for a television. How many weeks will it take her to save enough money to buy a television? Equation: t = 25 + 8.25w

Answers

Answer:

14 weeks

Step-by-step explanation:

t = 25 + 8.25w

Len  needs 135.75

135.75 =  25 + 8.25w

Subtract 25 from each side

135.75-25 = 25-25 + 8.25w

110.75 = 8.25w

Divide each side by 8.25

110.75/8.25 = 8.25w/8.25

13.42424 = w

Since we need at least 135.75, it will take Len a little more than 13 weeks, so it will take Len 14 weeks to have enough money

Answer:

14 weeks

Step-by-step explanation:

It will take 14 weeks for Len to save enough money to buy a television.

t = 25 + 8.25w

135.75 =  25 + 8.25w

a rectangular field has an area of 1,764m^2. the width of the field is 13m more then the length. what is the perimeter of the field?

Answers

Answer:

170 m

Step-by-step explanation:

Area of a rectangle is width times length:

A = WL

Given:

A = 1764

W = L + 13

Substitute:

1764 = (L + 13) L

1764 = L² + 13L

0 = L² + 13L − 1764

0 = (L + 49) (L − 36)

L + 49 = 0, L − 36 = 0

L = -49, L = 36

Since length can't be negative, L = 36 m.

So the width is W = L + 13 = 49 m.

Perimeter of a rectangle is twice the width plus twice the length.

P = 2W + 2L

P = 2(49) + 2(36)

P = 170 m

The perimeter is 170 meters.

Find the length of the segment indicated.

Answers

Answer:  The length of the indicated segment is 14.45 units.

Step-by-step explanation:  We are given to find the length of the indicated segment.

From the figure, we note that

A chord is bisected by the radius of the circle that makes a right-angled triangle with hypotenuse measuring 16.1 units and the other two sides measures x units and 7.1 units.

Using Pythagoras theorem, we get

[tex]x^2+7.1^2=16.1^2\\\\\Rightarrow x^2+50.41=259.21\\\\\Rightarrow x^2=259.21-50.41\\\\\Rightarrow x^2=208.8\\\\\Rightarrow x=\pm\sqrt{208.8}\\\\\Rightarrow x=\pm14.45.[/tex]

Since x is the length of side of a triangle, so we get

x = 14.45.

Thus, the length of the indicated segment is 14.45 units.

How do I solve two step equations?

1. 3x+5=-16

Answers

Answer:

x = - 7

Step-by-step explanation:

Given

3x + 5 = - 16 ( subtract 5 from both sides )

3x = - 21 ( divide both sides by 3 )

x = - 7

Two-step equations can get more difficult the higher the numbers get, but they're not too hard! ;)

To solve 3x+5=-16:

First subtract 5 from each side

Now its 3x=-21

Next divide 3 from each side

You get x=-7!

Always check your work! To check your work plug your answer "-7" into x.

So it looks like this: 3(-7)+5=-16 then distribute and solve!

You'll get -16=-16, that means its correct/true!

Jayne is studying urban planning and finds that her town is decreasing in population by 3%

each year. The population of her town is changing by a constant rate.

True

False

Answers

Answer:

True

Step-by-step explanation:

Let, [tex]P_0[/tex] be the initial population,

Given,

The population is decreasing by 3%  each year,

Thus, the population after t years would be,

[tex]P=P_0 (1-\frac{3}{100})^t[/tex]

[tex]\implies P=P_0(1+\frac{-3}{100})^t[/tex]

Since, if a population is changing by a constant rate then the population after t years is,

[tex]P=P_0(1+\frac{r}{100})^t[/tex]

Where, r is the rate of changing per period.

Hence, in the given situation the population is changing by the constant rate.

Answers

B.

Step-by-step explanation:

I think I'm going to go with the plug in method here.

If you get the same value on both sides, then the point is contained on the line.

A)

4x-y=-6

Test (-1,2):  4(-1)-2=-6

4(-1)-2=-6

-4-2=-6

-6=-6

True; the equation holds for (-1,2).

Test (3,1): 4(3)-1=-6

4(3)-1=-6

12-1=-6

11=-6

False; the equation doesn't hold for (3,1).

A isn't the right choice.

B)

x+4y=7

Test (-1,2): -1+4(2)=7

-1+4(2)=7

-1+8=7

7=7

True, the equation holds for (-1,2).

Test (3,1): 3+4(1)=7

3+4(1)=7

3+4=7

7=7

True, the equation holds for (3,1).

Since the equation held for both (-1,2) and (3,1) then B is the right answer.

-------------------Let's also go ahead and find the equation another way:

(3,1) and (1,-2) are points on your line.

I'm going to write an equation for these points in slope-intercept form first which is y=mx+b where m is slope and b is y-intercept.

I will then rearrange into standard form like your choices are in.

m=slope=rise/run.

To find this, I like to line up the points and subtract and then put 2nd difference over 1st difference.

Like so:

(-1,2)

-(3,1)

---------

-4    1

The slope is 1/-4 or -1/4.

So the equation so far is y=-1/4 x+b since m=-1/4.

Now to find b, I'm going to use y=-1/4 x +b along with one of the given points on the line like (x,y)=(-1,2).

y=-1/4 x+b

2=-1/4 (-1)+b

2=1/4+b

Subtract 1/4 on both sides:

2-1/4=b

7/4=b

So the equation of the line is y=-1/4 x +7/4.

Now the goal is to write in ax+by=c form where a,b,c are integers.

Multiply both sides of y= -1/4 x +7/4 by 4 giving you:

4y=-1x+7

Add 1x on both sides:

1x+4y=7

or

x+4y=7 since 1x=x

So x+4y=7 is the answer if you prefer this way. Well anyway you prefer, this is the correct standard form for this line.

The equation of line that passes through points (-1, 2) and (3, 1) will be

x + 4y = 7

Option B is true.

What is Equation of line?

The equation of line with slope m and y intercept at point b is given as;

y = mx + b

Given that;

The points on the line are  (-1, 2) and (3, 1).

Since, The equation of line will be;

y - y₁ = m (x - x₁)

Where, m = (y₂ - y₁)/ (x₂ - x₁) is slope of the line.

And, (x₁, y₁) is the point on the line.

Thus, Slope = (1 - 2) / (3 - (-1))

                  = (-1)/4

                  = -1/4

So, The equation of line with slope -1/4 and point (-1, 2) will be;

y - 2 = -1/4 (x - (-1))

4 (y - 2) = - 1(x + 1)

4y - 8 = -x - 1

x + 4y = 8 - 1

x + 4y = 7

So, The equation of line that passes through points (-1, 2) and (3, 1) will be

x + 4y = 7

A right triangle in which one acute angle is a reference angle for a 115 degree angle in standard position intersects the unit circle at (-0.423, 0.906). What is the approximate value of cos 115 degree?

Answers

Answer:

[tex]\cos (115\degree)=-0.423[/tex]

Step-by-step explanation:

The parametric equations of a circle is

[tex]x=r\cos \theta[/tex] and [tex]y=r\sin \theta[/tex]

The radius of the unit circle is 1 unit.

This implies that any point on the unit circle is represented by:

[tex]x=\cos \theta[/tex] and [tex]y=\sin \theta[/tex]

where [tex]\theta[/tex] is the angle in standard position,

From the question, the given angle in standard position is [tex]115\degree[/tex].

This angle intersects the unit circle at [tex]x=-0.423[/tex]

But [tex]x=\cos \theta[/tex]

We substitute [tex]\theta=115\degree[/tex] and [tex]x=-0.423[/tex]

This implies that: [tex]\cos (115\degree)=-0.423[/tex]

[tex]\displaystyle\frac{7}{9} \div \frac{4}{9} = a\frac{b}{c}[/tex]

The solving of the above expression can be done in the following manner:

[tex]\displaystyle\frac{7}{9} \div \frac{4}{9}\\\\\frac{7}{9}\times \frac{9}{4}\\\\\frac{7}{4} =\frac{(4\times 1) + 3}{4}= 1\frac{3}{4}[/tex]

Comparing the right side of the expression, we have,

[tex]a\displaystyle\frac{b}{c} = 1\frac{3}{4}[/tex]

Comparing, we get,

a = 1, b = 3, c = 4

Answers

[tex]\bf V=(x)(4x+3)(4x)\implies \cfrac{V}{4x}=(x)(4x+3)[/tex]

Answer:

[tex]V=(x)(4x+3)(4x)=16x^2+12x[/tex]                        

Step-by-step explanation:

Given : Expression [tex]V = (x)(4x+3)(4x)[/tex]

To find : Suppose you multiplied the cereal box dimensions in a different order ?

Solution :

The given expression is the product of three numbers,

[tex]V = (x)(4x+3)(4x)[/tex]

First we multiply first two terms,

[tex](x)(4x+3)=4x^2+3x[/tex]

Substitute back,

[tex]V = (4x^2+3x)(4x)[/tex]

Then multiply the left terms,

[tex]V =16x^2+12x[/tex]

Therefore, [tex]V=(x)(4x+3)(4x)=16x^2+12x[/tex]
