Answer:

a =4 b=8 c=-8

y-value of vertex =

ah^2 + bh + c

where h = -b/2a

h= -8/8 =-1

y-value of vertex =

4(-1)^2 + 8*-1 -8

4 -8 -8

y value of vertex = -12

podryga [215]

Answer:

When $a=\frac{1}{4}$ and $b=6$ :

$-8ab=-12$

Step-by-step explanation:

-8ab can be seen as -8×a×b. Insert the given values:

$-8*\frac{1}{4} *6$

Simplify multiplication from left to right:

$-8*\frac{1}{4} \\\\\frac{-8}{1} *\frac{1}{4} =\frac{-8}{4} =-2$

Insert and solve:

$-2*6=-12$

What is the constant of proportionality in the equation 3y=2x

Inessa05 [86]

Answer:

2/3

Step-by-step explanation:

3y = 2x

Divide each side by 3

3y/3 = 2x/3

y = 2/3 x

The direct variation relationship is

y = kx

(Evaluate each logarithm. Use the change of base formula when necessary) helpppp y’all

Dmitry [639]

The value of $\log _{6}(36)$ is 2.

Solution:

Given expression is $\log _{6}(36)$ .

<u>To evaluate the expression:</u>

$\log _{6}(36)$

36 can be written as 6².

$=\log _{6}\left(6^{2}\right)$

Using log rule: $\log _{a}\left(x^{b}\right)=b \cdot \log _{a}(x)$

$=2 \log _{6}(6)$

Using log rule: $\log _{a}(a)=1$ so that $\log _{6}(6)=1$

= 2(1)

= 2

$\log _{6}(36)=2$

Hence the value of $\log _{6}(36)$ is 2.
