Answer:

f(3) = 425

f(3) is the elevation of a mountain climber after 3 hours of climbing.

Step-by-step explanation:

So we are given a line that relates time to elevation. We are also given that the equation of the line is f(x) = 125x + 50. From looking at the graph given, we can see that x is the time, in hours, and y, or f(x), is the height, in feet. We are asked to find f(3) and interpret it's meaning.

To find f(3), we would have to find what f(x) is when x = 3. To do this, lets plug in 3 for x into the given equation:

f(3) = 125(3) + 50 = 425

So f(3) = 425. Now, we already know that x is the time in hours and y, or f(x), is the elevation in feet. We set x to 3 when solving for f(3). We have also found that f(3), or y when x = 3, is 425. So f(3), or 425, is the elevation after 3 hours.

I hope you find my answer and explanation to be helpful. Happy studying.

Answer:

50° for angle FEG

Step-by-step explanation:

Following the Verticle Angles Theorem, the angle on the other side of 140 must also be 140. Since it is split up and we know one of them is a right angle, we must subtract 90 from 140.

140 - 90 = 50.

Thus, angle FEG is 50°.

[tex]x + y = 90[/tex]

[tex]x = 3y[/tex]

[tex]3y + y = 90[/tex]

[tex]4y = 90[/tex]

[tex]y = 15[/tex]

[tex]x = 3(15) = 45[/tex]

Answer:

45 °

Step-by-step explanation:

Knowing that:

Supplementary Angle = 180 °

Angle x is 3 time the measure of angle y.

Solve:

Equation below:

x + y = 180

x = 3y

Substitute

3y + y =180

4y = 180

Divide both sides by 4

4y/4 = 180/4

y = 45

Value of x:

x = 3 × 45

x = 135

Therefore the measure of angle x is 135.

x = 45

y = 135

Answer:

$189.43

Step-by-step explanation:

P = regular price

65% as a decimal = [tex]\frac{65}{100}[/tex] = .65

Discount = .65

To get the amount of the discount we would multiply P * .65

To find the sale price we subtract the discount from the original price.

Now we write our equation:

P - P(.65) = $66.30  

Solve for P

P - P(.65) = $66.30  

1P - P(.65) = $66.30  

1P - .65P = $66.30  

.35P = 66.30   Divide each side by .35

.35P.35 = 66.30/.35

P = 66.30/.35

P ≈ $189.43

Answer:

[tex]y = 2x^4[/tex]

Step-by-step explanation:

The given statement can be represented as:

[tex]y\ \alpha\ x^4[/tex]

[tex]x =3; y = 162[/tex]

Given

Represent this as an equation

[tex]y\ \alpha\ x^4[/tex]

Convert variation to equation

[tex]y = kx^4[/tex]

Where k is a constant of variation.

Substitute [tex]x =3; y = 162[/tex]

[tex]162 = k * 3^4[/tex]

[tex]162 = k * 81[/tex]

Solve for k

[tex]k = 162/81[/tex]

[tex]k =2[/tex]

To get the equation, we have:

[tex]y = kx^4[/tex]

Substitute 2 for k

[tex]y = 2x^4[/tex]

The equation describing the relationship of the given variables is [tex]y=\frac{81}{162}x^4[/tex]

If y varies directly to the fourth power of x, this can be expressed as:

[tex]y \alpha x^4\\y=kx^4\\[/tex]

Given that x = 3 and y = 162, the equation becomes;

[tex]162 = k(3^4)\\162 = 81k\\k=\frac{81}{162}[/tex]

Substitute the value of k into the expression above to have:

[tex]y=kx^4\\y=\frac{81}{162}x^4[/tex]

Hence the equation describing the relationship of the given variables is [tex]y=\frac{81}{162}x^4[/tex]

Step-by-step explanation:

x = Iman's money

y = Daphne's money

x = 2y

x - 128 = y - 40

now we use the first equation as identity in the second equation and get

2y - 128 = y - 40

y - 128 = -40

y = $88

x = 2y = $176

these were the starting values.

now, after spending, they have both left

176 - 128 = 88 - 40 = $48

Answer:

The number must be a negative integer because -4+ any negative is a negative

Answer:

11 hours

Step-by-step explanation:

Using the $79 dollars, Scott can get up to 9 hours with the boat. Scott will be left with $7, adding the $7 to the $9 coupon, Scott will then have $16 which can give Scott an additional 2 hours summing the total hours up to 11 hours Scott can rent the boat for.

spent : 2/5 + 1/4 = 8/20 + 5/20 = 13/20

remains = 7/20

The 7/20th fraction of his lotto earnings is remaining.

Let us say the man has $100

Money spent on luxury cars = 2/5 of the money

Money spent on luxury cars = 2/5 * 100 = $40

Money spent on buying a house = 1/4 of the money

Money spent on buying a house = 1/4 * 100 =$25

Money left with the man = 100-40-25 = $35

$35 is 35/100 fraction of $100.

35/100 = 7/20

So, the 7/20th fraction of his lotto earnings is remaining.

Hence, the 7/20th fraction of his lotto earnings is remaining.

i cant rewrite everything i solve in the paper sorry

Step-by-step explanation:

In this question, to find the total height first, we must also take into consideration the acceleration due to gravity as well. To find the distance by which acceleration due to gravity pulls the ball down must know the Initial velocity.

In the answer key, it says that gravity changes the ball's height by a distance of -5t^2

Is initial velocity in this question 0 or 14m/s? Because if it is 14, then gravity should change the balls position by -(14+5t^2), not -5t^2, because if I remember correctly, the formula for finding distance is vt(initial velocity)+(1/2)at^2 ,and not just (1/2)at^2
