Find the value of c that completes the square
Kitty [74]

Answer:

c = 64

Step-by-step explanation:

Given

x² - 16x + c

To complete the square

add ( half the coefficient of the x- term )² to x² - 16x

x² + 2(- 8)x + 64

= (x - 8)²

Thus

x² - 16x + 64 = (x - 8)² ← a perfect square

with c = 64

What is the inverse of the function f(x) = 2x - 10?
Oxana [17]

Answer:

h(x) = 1/2x + 5

Step-by-step explanation:

Switch the positions of the x and y (f(x)) and solve for y (f(x)).

f(x) = 2x - 10

x = 2y - 10

x + 10 = 2y

(x + 10)/2 = y

1/2x + 5 = y

Nuno set up a series of dominoes. he starts by knocking over 10 dominoes. every second after that, the number of dominoes that a
vesna_86 [32]
It will take 8 seconds for all of the dominoes to fall over.

This will be an exponential function.  To find the growth rate, we can write out the terms of the sequence that goes along with it:  10, 20, 40, ...

"Growth rate" is the same as percent of increase or decrease.  We find the amount of increase and divide by the original amount:  20-10 = 10 increase; 10/10 = 1.

The exponential function is of the form
f(x) = a*(1+r)ˣ, where a is the initial value (10), r is the growth rate (1), and x is the number of time periods.  Using the variables given to us in the problem along with this information, we have:

d(s)=10(1+1)^s
\\
\\2560=10(2)^s

Divide both sides by 10:
\frac{2560}{10}=\frac{10(2)^s}{10}
\\
\\256=2^s

We will use logarithms to solve this:
\log_2 256=s
\\8=s
