Answer:

Rate of change = -1

Step-by-step explanation:

Given:

f(x) = -½(x + 2)² + 5

Required:

Average rate of change from x = -3 to x = 1

Solution:

Rate of change = \frac{f(b) - f(a)}{b - a}

Where,

a = -3,

f(a) = f(-3) = -½(-3 + 2)² + 5 = -½(-1)² + 5 = 4.5

b = 1,

f(b) = f(1) = -½(1 + 2)² + 5 = -½(9) + 5 = 0.5

Plug in the values into the formula:

Rate of change = \frac{0.5 - 4.5}{1 - (-3)}

Rate of change = \frac{-4}{4}

Rate of change = -1

Lines x and y are parallel and are cut by the transversal b. If the measure of angle 1 is 57°, what is the measure of angle 6? E
lana [24]

Answer:

\angle6=123

Step-by-step explanation:

Given

Lines x and y

Transversal b

\angle 1 = 57

Required

Find \angle 6

From the attachment, \angle1 and \angle7 are vertically opposite.

This means that

\angle 1 =\angle 7 = 57

Similarly

\angle 7  and \angle 6 are supplementary angles

So:

\angle7 + \angle6=180

Make \angle6 the subject

\angle6=180-\angle7

\angle6=180-57

\angle6=123

The relationship between \angle1 and \angle6 is that they are supplementary angles because:

\angle6+ \angle1=180

Decide whether or not the figures are similar. Explain why or why not.
AleksAgata [21]

Step-by-step explanation:

To tell if JKON and JKLM are similar, compare the ratios between corresponding sides.  For example:

JK / KO = 5/8

JK / KL = 5/22

The ratios aren't the same, so the shapes aren't similar.
