Answer:

here's an example to help you out man Let n = how much each new member must pay each month.

$160 - $28 = $132

n = $132 ÷ 12 months in a year

n = $11

You can also look at it this way:

n = (160 - 28)/12

Answer:

a) Time left = [45 - (3j + 5s)] minutes

b) 17 minutes

Step-by-step explanation:

a) Using j for the number of laps she jogs and s for the number of times she stretches. Since Bailey has a total of 45 minutes to complete his exercise, then;

Time left = [45 - (3j + 5s)] minutes

If she jogs 6 laps and stretches 2 times , then;

Time left = [45 - (3j + 5s)]

b) Where j = 6 and s = 2,

Time left = 45 - (3(6) + 5(2))

              = 45 - (18 + 10)

              = 45 - 28

              = 17

Amount of time Bailey has left is 17 minutes.

Answer:

-33/56

Step-by-step explanation:

suppose: A,B are the 2 angles of a triangle

we have: A = arcsin[tex]\frac{-4}{5}[/tex]

               B = arctan [tex]\frac{5}{12}[/tex]

=> sin A = [tex]\frac{-4}{5}[/tex] => cos A = [tex]\sqrt{1-\frac{(-4)^{2} }{5^{2} } } =\frac{3}{5}[/tex] (because A is in quadrant IV)

    tan B = [tex]\frac{5}{12}[/tex]

have:

[tex]1+ cot^{2}B=\frac{1}{sin^{2}B } => 1+\frac{1}{tan^{2} B}=\frac{1}{sin^{2}B } \\=> 1+\frac{1}{\frac{5^{2} }{12^{2} } } =\frac{1}{sin^{2}B }\\ => sin^{2}B=\frac{25}{169}[/tex]

because B is in quadrant III => [tex]sin B=-\sqrt{\frac{25}{169} }=\frac{-5}{13}=>cosB=-\sqrt{1-\frac{5^{2} }{13^{2} } }=\frac{-12}{13}[/tex]

tan(arcsin(-4/5)+arctan(5/12)) = tan( A + B)

but A,B are the 2 angles of a triangle => tan(A + B) = [tex]\frac{sin(A+B)}{cos(A+B)}[/tex]

have: sin(A+B) = sinA.cosB + cosA.sinB = [tex]\frac{-4}{5}.\frac{-12}{13} +\frac{3}{5}.\frac{-5}{13}=\frac{33}{65}[/tex]

cos(A + B) = cosA.cosB - sinA.sinB =[tex]\frac{3}{5}.\frac{-12}{13}-\frac{-4}{5}.\frac{-5}{13}=\frac{-56}{65}[/tex]

=> tan(A + B) = [tex]\frac{33}{65}:\frac{-56}{65}=\frac{-33}{56}[/tex]

Answer:

[tex]h(f(x)) = 18x -22[/tex]

Step-by-step explanation:

Given

f (x) = [tex](3x-5)^3[/tex]

[tex]h(x) =2\sqrt[3]{3x} + 8[/tex]

We are to find the composite function [tex]h(f(x))[/tex]

[tex]h(f(x))[/tex][tex]= h ((3x-5)^3)[/tex]

To get [tex]h ((3x-5)^3)[/tex], we will substitute x as (3x-5)³ in h(x)as shown:

[tex]h(x) =2\sqrt[3]{3(3x-5)^3} + 8\\h(f(x)) =2(3(3x-5)+ 8\\h(f(x)) = 2(9x-15)+8\\h(f(x)) =18x-30+8\\h(f(x)) = 18x - 22[/tex]

Step-by-step explanation:

30 times 7 is 210 and 350 times 19 cents is 35

Answer:

The equation is y = 30d + 0.10m. The cost is $245.

Step-by-step explanation:

Plug in the values for the equation. The equation will become y = 30(7) + 0.10(350). Solve to get y = 210 + 35. This equals y = 245.

Answer:

45 lessons

Step-by-step explanation:

Here, we want to know the number of lessons that both of them would have completed when they earn pizza and cookies at the same time

From the question, we are told that they earn cookies and pizza when they complete 9 and 15 lessons respectively.

So to know the number of lessons completed, we need to find the lowest common multiple of the number of cookies and the numbers of pizza

That will be lowest common multiple of 9 and 15

This is 45

Answer:

Photo 1: x=5 y=-2

Photo 2: x=11/5 y=4

Step-by-step explanation:

Photo 1-

2x + 3y = 4

              x = 2 − 3/2y

              y = 4/3 - 2/3x

2x + 3y = 4

              x = 2 - 3/2y

              y = 4/3 - 2/3x

Photo 2-

5x + 3y = 23

              x = 2 − 3/2y

              y = 4/3 − 2/3x

3y = 15x - 21

              x = y/5 + 7/5

              y = 5x − 7

Answer:

7.1 × 10 7

Step-by-step explanation:

Move the decimal so there is one non-zero digit to the left of the decimal point. The number of decimal places you move will be the exponent on the 1010. If the decimal is being moved to the right, the exponent will be negative. If the decimal is being moved to the left, the exponent will be positive.

Answer:  D)  [tex]7.1 \times 10^7[/tex]

Explanation:

Place the decimal point between the first two digits of the given number. Erase everything after the '1'. So we have 7.1

To get back to 71,000,000 we would need to move the decimal point 7 spaces to the right

So that's why [tex]7.1 \times 10^7 = 71,000,000[/tex]

If the exponent was -7, then we would move the decimal point 7 spaces to the left.

Step-by-step explanation:

Number of eggs laid per week = between 18 and 25

Let x = exact number of eggs laid

Using inequality :

18 ≤ x ≤ 25

Number of eggs Pat eats = 2

18 - 2 ≤ x ≤ 25 - 2

Eggs left after pat eats 2 of the eggs :

16 ≤ x ≤ 23

Hence,

Eggs eaten by pat's dogs :

E = 16 ≤ x ≤ 23

Answer: I think it's D.

Step-by-step explanation:

I'm on the same thing and my best answer is Both functions are increasing, but function g increases at a faster average rate.

Both functions are increasing, but function g increases at a faster average rate.

x         f(x)

-2        -46

-1         -22

0         -10

1           -4

2          -1

If the slope of a function is continuously increasing or constant in an interval, the function is known as an increasing function.

Let us assume [tex]f(x)=ab^x+c[/tex]

at x=0, f(0)=-10

So, [tex]-10=a+c[/tex]

Similarly, by satisfying the above table in the f(x)

[tex]f(x)=-\frac{33}{5} (\frac{1}{11} )^x-\frac{17}{5}[/tex]

[tex]f'(x) > 0[/tex]

So we can say that f(x) is an increasing function.

[tex]g(x)=-18(\frac{1}{3} )^x+2[/tex]

[tex]g'(x)=-18(\frac{1}{3} )^xln(\frac{1}{3} )[/tex]

[tex]ln\frac{1}{3} < 0[/tex]

So, [tex]g'(x) > 0[/tex]

So, g(x) is an increasing function.

For any x∈f(x) and  x∈g(x) [tex]g'(x) > f'(x)[/tex]

So, g increases at a faster average rate

Thus,  Both functions are increasing, but function g increases at a faster average rate.

The value of the function f(g(2))  is: f(g(2)) = -12

Here,

To find the value of f(g(2)),

we first need to find the value of g(2), and then use that result as the input for the function f.

Given:

f(x) = 2x - 4

g(x) = -5x + 6

Step 1: Find g(2)

g(2) = -5(2) + 6

g(2) = -10 + 6

g(2) = -4

Step 2: Use the result g(2) as the input for f(x)

f(g(2)) = f(-4)

f(x) = 2x - 4

f(-4) = 2(-4) - 4

f(-4) = -8 - 4

f(-4) = -12

Therefore, f(g(2)) = -12.

Answer:

y = a ÷ (πx)

Step-by-step explanation:

An equivalent equation solved for y is:

y = a/πx

An equation is a pair of algebraic equations with the equal sign (=) in the middle and the same value.

The formula a = xy, where x and y are the halved lengths of the ellipse's biggest and smallest diameters, may be used to calculate the area, a, of an ellipse.

Starting from the formula a = πxy, we can rearrange it to solve for y:

a = πxy

Dividing both sides by πx, we get:

a/πx = y

y = a/πx

Therefore, an equivalent equation solved for y is:

y = a/πx.
