Factor please <br> x^2+8x+15
Anastasy [175]

Answer:

(x + 3)(x + 5)

Step-by-step explanation:

The given expression is x^2 +8x + 15

Now find the factor of 15 such that when you add the factors, we have to get 8

The right factors of 15.

5 * 3 = 15

5 + 3 = 8

The right factors are 3 and 5.

x^2 + 8x + 15 = (x + 3)(x + 5)

Therefore, x^2 + 8x + 15 = (x + 3)(x + 5)

Thank you.

Peter puts 8000 into a savings account that pays 6% interest, compounded continuously. After 5 years, Peter will have ( $)
guajiro [1.7K]
We have to calculate the amount of money Peter will have in his account after 5 years. Formula for the amount after t years with interest compounded continuously : A = P * e ^(rt)
We know that r = 0.06, t=5, e = 2.71 and p= $8,000 
A = 8,000 * 2,718 ^(0.06 * 5) = 8,000 * 2,718 ^ (0.3) = 8,000 * 1.3488158  = 10,798.53 so the answer is 10,798.53

Find the standard form of the equation of the parabola with a focus at (7, 0) and a directrix at x = -7.
Alecsey [184]

<u><em>Answer:</em></u>

y^2 = 28x

<em><u>Step-by-step explanation:</u></em>

Since the directrix is horizontal, use the equation of a parabola that opens left or right.

(y−k)^2 = 4p(x−h)

Find the vertex.

(0,0)

Find the distance from the focus to the vertex.

p = 7

Substitute in the known values for the variables into the equation

(y−k)^2 = 4p(x−h).

(y−0)^2 = 4(7)(x−0)

Simplify.

<em>y^2 = 28x</em>
