The y-intercept for the function g(x) is 4.

The y-intercept of a function is a point where the line crosses the y-axis. The linear function can be given as below.

f(x) = mx+n

Where m is the slope of the line and n is a real number and y-intercept of the line.

The given function is f(x)=-4x—2.

The function is vertically translated 6 units up to g(x).

The y-intercept of the function f(x) is -2. Then the y-intercept for the function g(x) can be given as below.

y-intercept g(x) = -2+6

y-intercept g(x) = 4

Hence,  the y-intercept for the function g(x) is 4.

The momentum change of the rock caused by its fall will be 35.49 x [tex]10{-24[/tex] m/sec and the magnitude of the earth velocity will be 212.94 kgm/s

We have,

Mass of the rock = 18 kg

Distance traveled = 7 m

Mass of earth = 6 x [tex]10^{24[/tex] Kg

Using second equation of motion

S= ut  + 1/2 at²

If the body freely falls initial velocity will be zero.

u = initial velocity = 0

Then, S = 1/2 at²

7 = 1/2 x 10 x t²

14/ 10= t²

t= 1.183 sec

Now, Change in the momentum of the rock will be,

ΔP= FΔT

ΔP = (mg ) ΔT

ΔP= (18) x  10 x 1.183

ΔP=212.94 kg-m/s²

The equation r²cos²(θ) - 2rcos(θ) + r²sin²(θ) = 8 to rectangular form is (x - 1)² + y² = 9

From the question, we have the following parameters that can be used in our computation:

r²cos²(θ) - 2rcos(θ) + r²sin²(θ) = 8

The above equation is in its polar form, where

r² = x² + y²

cos(θ) = x/r

sin(θ) = y/r

Rearrange the terms in r²cos²(θ) - 2rcos(θ) + r²sin²(θ) = 8

So, we have

r²cos²(θ)  + r²sin²(θ) - 2rcos(θ) = 8

Factorize

r²(cos²(θ)  + sin²(θ)) - 2rcos(θ) = 8

In trigonometry

cos²(θ)  + sin²(θ) = 1

So, we have

r² - 2rcos(θ) = 8

Recall that

r² = x² + y²

cos(θ) = x/r

So, we have

x² + y² - 2r * x/r = 8

Evaluate

x² + y² - 2x = 8

Rearrange

x²  - 2x + y² = 8

Express as perfect squares

(x - 1)² + y² = 8 + 1

So, we have

(x - 1)² + y² = 9

Hence, the equation to rectangular form is (x - 1)² + y² = 9

To Determine the predicted increase in the amount of money spent on entertainment for an increase of one hour in time worked, we need to find the slope of the line, which is the coefficient of x in the equation.

We are given that the equation of the line of best fit, y = −0.76x8.76

The slope is 1.86, that means that for every one unit increase in x (which in this case is one hour worked), y (in this case is the amount of money spent on entertainment) is predicted to increase by 1.86 units.

slope = -5, y intercept = 2

The graph is below.

======================================

Work Shown:

20x+4y = 8

4y = 8-20x

4y = -20x + 8

y = (-20x+8)/4

y = -20x/4 + 8/4

y = -5x + 2 is the final answer

slope = -5, y intercept = 2

Two points on this line are (0,2) and (1, -3)

The graph is below. I used GeoGebra to make it, but Desmos is another good choice.

The y-intercept of the line is 2.

In the equation y = 9x + 2, x and y are variables that represent the coordinates of any point on the line.

To find the Y-intercept, we need to find the value of y when x equals 0.

When x equals 0, the equation becomes:

y = 9(0) + 2

Any number multiplied by 0 is 0, so the first term drops out and we are left with:

y = 0 + 2

Which simplifies to:

y = 2

Therefore, when x equals 0, y equals 2. This means that the point (0, 2) is on the line. In other words, the line intersects the y-axis at y = 2, which is the Y-intercept of the line.

The formula for the inverse function h⁻¹(P) is:

The population of insects in the lab experiment is 90, then the number of days it takes for the population to reach that size is approximately 17.5 days.

To find the inverse function h⁻¹(P), we need to solve the equation P = h(t) for t in terms of P.

Starting with P = h(t) = [tex]100/1+4e^-^0^.^0^5^t[/tex]

we can first multiply both sides by [tex]1+4e^-^0^.^0^5^t[/tex] to get:

[tex]P(1+4e^-^0^.^0^5^t) = 100[/tex]

t = -20ln(4/(P-100)+1)

Therefore, the formula for the inverse function h⁻¹(P) is:

h⁻¹(P) = -20ln(4/(P-100)+1)

(b) To find h⁻¹(90)

we substitute P = 90 into the formula for h^-1(P):

h⁻¹(90) = -20ln(4/(90-100)+1)

= 17.5

This means that if the population of insects in the lab experiment is 90, then the number of days it takes for the population to reach that size is  17.5 days.

Answer: The cost of a large pizza with 2 toppings depends on the pizza place. Let's say the cost is $15 per pizza, and each additional topping costs $2.

Let t be the number of toppings Anna has on her pizza. Then, the total cost of her pizza can be expressed as:

Total cost = $15 + $2t

Since Anna has 2 toppings on her pizza, we can substitute t = 2:

Total cost = $15 + $2(2)

Total cost = $15 + $4

Total cost = $19

Therefore, the total cost of Anna's pizza with 2 toppings is $19.

The best reason why 2/5 is the exact quotient for 1/4 divided by 5/8 is: ²/₅ * ⁵/₈ = ¹/₄

To divide fractions, firstly, you need to turn the 2nd fraction upside down. For example, 3/8 divided by 3/4 would be 3/8 divided by 4/3. After you have flipped the second fraction, you multiply them - 3*4 = 12. 8*3 = 24 so the answer would be 12/24. Which then could be cancelled down to 1/2.

Now, from the given question, we can say that:

1/4 ÷ 5/8

Now, from the earlier step in dividing fractions, the next step is to turn the 2nd fraction upside down and multiply by the first to get:

Invoice price = $299,000

Applicable sales tax = $2,100

Freight paid = $1,160

Cost of insurance coverage = $1,025

Installation costs = $1,900

The frequency of the lowest note = 523.25 Hz

Whereby the frequency of the lowest note = The fundamental frequency

The acoustic length formula for finding the length of the pipe, L, can be presented as follows;

L = (v/(2·f)) × √(1 + 4·A²/v²)

Where;

L = The length of the pipe

f = The frequency = 523.25 Hz

The exponential function that models the relationship between the two points is [tex]y = 41.62 (1.0824)^x.[/tex]

We have,

To write an exponential model given two points (6,85) and (7,92), we can use the general exponential function form:

y = a[tex]b^x[/tex]

where y is the dependent variable, x is the independent variable, a is the initial value (when x = 0), and b is the base of the exponential function.

To find the values of a and b, we can use the two given points as follows:

When x = 6, y = 85:

85 = a b^6

When x = 7, y = 92:

92 = a b^7

We now have a system of two equations with two unknowns (a and b).

We can solve for a by dividing the second equation by the first equation:

92/85 = (ab^7) / (ab^6)

1.0824 = b

Substitute this value of b into one of the equations to solve for a:

85 = a (1.0824)^6

a = 41.62

Therefore,

where

When we enter the values, we obtain:

FV = 600 * (((1 + 0.12/4)^(4*60)) - 1) / (0.12/4) = 498,174.72

If your objective is to save $300,000 over 25 years, you would need to put away around $3077.41 every six months.

To solve this problem, we can use the formula for the future value of an annuity:

where FV is the future value, P is the periodic payment, r is the annual interest rate, n is the number of compounding periods per year, and t is the number of years.

Since the interest is compounded annually, we have n = 1 and r = 0.05. To find the periodic payment P, we can rearrange the formula:

P = FV * (r/n) / ((1 + r/n)^(n*t) - 1)

Plugging in the given values, we have:
