Answer:

0.75

Step-by-step explanation:

Put the number where the variable is and do the arithmetic.

3(1.5² -2) = 3(2.25 -2) = 3(0.25) = 0.75

Which expression below gives the average rate of change of the function h(x)=4^(x+2)+7 on the interval –3 ≤ x ≤ 5?

viktelen [127]

Answer:

$\frac{4^8-1}{32}$

Step-by-step explanation:

$h(x)=4^{(x+2)} +7$

We know that formula for average rate of change of a function from a to b is

$\frac{f(b)-f(a)}{b-a}$

Here f equals h and a =-3 b=5

h(a) = $4^{5+2} +7 = 4^7+7$

and

h(b) = $4^{-3+2} +7 = \frac{1}{4} +7$

h(b)-h(a) = $4^7-\frac{1}{4} =\frac{4^8-1}{4}$

b-a = 5-(-3) =8

Hence average rate of change is

$\frac{4^8-1}{4}(\frac{1}{8} )=\frac{4^8-1}{32}$

Answer:

multiply the left side of the constant vector by the inverse matrix

Step-by-step explanation:

The matrix equation ...

AX = B

is solved by left-multiplying by the inverse of A:

A⁻¹AX = A⁻¹B

IX = A⁻¹B . . . . . the result of multiplying A⁻¹A is the identity matrix

X = A⁻¹B . . . . . B needs to be multiplied by the inverse matrix

$\left[\begin{array}{c}x&y\end{array}\right] = \left[\begin{array}{cc}-4&1\\3&2\end{array}\right]^{-1}\left[\begin{array}{c}9&7\end{array}\right]=\dfrac{1}{11}\left[\begin{array}{cc}-2&1\\3&4\end{array}\right]\left[\begin{array}{c}9&7\end{array}\right]=\left[\begin{array}{c}-1&5\end{array}\right]$

Please Help Fast!! 15 Point and brainiest if correct

iragen [17]

If a < b, then dividing both sides by a positive number will not flip the inequality sign. The inequality flips if you divide both sides by a negative number.

So if a < b, then a/3 < b/3 as well.

<h3>Answer: Less than sign (first choice)</h3>
