No, the solution to the equation would have to have an x value, the first term in the parentheses, have the value of the y value, the second term in the parentheses.

To figure this out, plug (1, -4) into the equation y=-2x. 1 is the x value, so we plug it into the x. -4 is the y value, so we plug it into the y spot. In the end we get -4=-2(1). Is this true? No, it isn't. Therefore it is not an answer.

If this helped please give brainliest, rate, and thank!

So you will need to find the height, and we can do so by using the pythagorean theorem, which is leg^2+leg^2=hypotenuse^2 . Using this formula, we can make the equation 15^2+h^2=25^2


Firstly, solve the exponents: 225+h^2=625


Next, subtract 225 on both sides: h^2=400


Lastly, square root both sides, and your answer is h = 20.



Now that we got the height, we can solve for the volume, which is V=\pi r^2\frac{h}{3} . Using this formula, we can form our equation to be V=\pi 15^2\frac{20}{3}


Firstly, solve the exponent: V=\pi*225*\frac{20}{3}


Next, multiply 225 and 20/3, and your answer will be V = 1500π, or the third option.

Given the definitions of f(x) and g(x) below, find the value of (gºf)(-5).
jolli1 [7]

Answer:

(g ○ f)(- 5) = 4

Step-by-step explanation:

evaluate f(- 5) then substitute the value obtained into g(x)

f(- 5) = (- 5)² + 6(- 5) + 3 = 25 - 30 + 3 = - 2 , then

g(- 2) = 2(- 2) + 8 = - 4 + 8 = 4

(g ○ f)(- 5) = 4

The expression 15a+12c is the cost of admission at an amusement park for a adults and c chldren. Then find the total cost for 5
siniylev [52]

We are given expression for cost of admission at an amusement park : 15a+12c.

Where a is the number of adults and

c is the number of children.

We need to find the total cost of 5 adults and for 10 children.

<em>In order to find the total cost of 5 adults and for 10 children, we need to plug a=5 and c=10 in 15a+12c expression.</em>

Plugging a=5 and c=10 in 15a+12c expression, we get

15(5) + 12(10) = 75 + 120 = $195.

<h3>Therefore, the total cost for 5 adults and for 10 children is $195.</h3>

Paladinen [302]
We just need to subtract the total miles he has already rode from the total miles of the path.
12.25-11.5
0.75
So, he must bike 3/4 miles to reach the end.
