What is the axis of symmetry for the function f(x)=7−4x+x2?
Rufina [12.5K]

Answer:

Answer:

x = 2

Step-by-step explanation:

The vertex form of the parabola is given by  

Comparing this equation with vertex form of a parabola , where (h,k) is the vertex

h = 2

k = 3

Hence, vertex is (2,3)

Now, axis of symmetry of a parabola passes through the vertex and divide the parabola in two equal halves.

Hence, axis of symmetry of the parabola is given by

x = h

x = 2

Third option is correct.

Solve this equation. -4(p+2)+8=2(p-1)-7p+15
ratelena [41]
Hey there! 

First we have to distribute! 

-4 (p +2) = +8 = 2(p - 1) -7p + 15 \\  -4(p) + -4(2) + 8 = 2(p) +-2 + -7p + 15

Now, we have to combine our like terms 

-4p + (-8 + 8) = 2p + (-7p) + (-2) + 15 


Once we solve all the like-terms we get 

-4p = 5p +13

Now, we have to add 5p to each of your sides 

-4p + 5p \\ = -5p + 13 + 5p

Solve that part of the equation 

p= 13

Good luck on your assignment and enjoy your assignment

How long would it take to double your principal in an account that pays 6.5% annual interest compounded continuously? round your
prisoha [69]
It would take 10.7 years.

The formula for continuously compounded interest is:
A=Pe^{rt}
where P is the principal, r is the interest rate as a decimal number, and t is the number of years.

Using our information we have:
A=Pe^{0.065t}

We want to know when it will double the principal; therefore we substitute 2P for A and solve for t:
2P=Pe^{0.065t}

Divide both sides by P:
\frac{2P}{P}=\frac{Pe^{0.065t}}{P}
\\
\\2=e^{0.065t}

Take the natural log, ln, of each side to "undo" e:
\ln{2}=\ln{e^{0.065t}}
\\
\\0.6931471806=0.065t

Divide both sides by 0.065:
\frac{0.6931471806}{0.065}=\frac{0.065t}{0.065}
\\
\\10.7\approx t
