When you multiply a function by -1 what is the effect on its graph? apex

1 answer:

8 0

The graph flips over the x- axis is the best answer. When you multiply a function by -1, you actually multiply both sides of the equation by- 1, . Doing so will give you the same line. If the equation has an intercept, the line will flip over the horizontal line at the intercept

The average price (in dollars) to rent a studio in a certain city can be approximated by the equation p=28.2t+644 where t is the

egoroff_w [7]

$p = 28.2t + 644\\\\p-644 = 28.2t\\\\\frac{p-644}{28.2} = \frac{28.2t}{28.2}\\ \\t = \frac{p-644}{28.2}$

$t = \frac{1320.80-644}{28.2} \\\\t = 24$

It will take 24 years.

Show the work for answer, if the area of a pizza is 153.94 square inches, find the length of its diameter

TEA [102]

Answer:

14 inch

Step-by-step explanation:

A = πr^2

153.94 = π * r^2

153.94/π = 49.001 = r^2

√49.001 = r = 7

radius * 2 = diameter

7 * 2 = 14 inch diameter

Find the measure of ∠EGC. Circle A with chords EF and CD that intersect at point G, the measure of arc EC is 50 degrees, the mea

miv72 [106K]

Answer:

m∠EGC=70°

Step-by-step explanation:

we know that

The measure of the inner angle is the semi-sum of the arcs comprising it and its opposite

m∠EGC=(1/2)[arc EC+arc DF]

Find the value of x

we have

m∠EGC=(7x+7)°

arc EC=50°

arc DF=10x°

substitute and solve for x

(7x+7)°=(1/2)[50°+10x°]

14x+14=50+10x

14x-10x=50-14

4x=36

x=9

Find the measure of angle EGC

m∠EGC=(7x+7)°

substitute the value of x

m∠EGC=(7(9)+7)°=70°
