Answer:

Here’s something I wrote that can help you. I don’t really wanna do transformations but this should help you get the answer in a snap.

ONLY FOR REFLECTIONS

Over the x-axis: (x, y) — > (x, –y)

Over the y-axis: (x, y) — > (–x, y)

Over the line y = x: (x, y) — > (y, x)

Through the origin: (x, y) — > (–x, –y)

So for example E is (6,-1)

Over the y axis so following the coordinate plane rules, (6,-1) — > (-6, -1)

(-6, -1) over x axis which is following the rules

(-6, -1) — > (-6, 1)

Final answer (-6,1)

The volume of a sphere whose diameter is 18 centimeters is π cubic centimeters. If its diameter were reduced by half, its volume

lbvjy [14]

Answer:

3053.5517 cm^3 ; 1/8

Step-by-step explanation:

Given the following :

Volume (V) of sphere = (4/3)πr^3 where r = radius

Diameter of sphere = 18 ; radius(r) = diameter / 2 = 18/2 = 9cm

V = (4/3) × π × 9^3

V = 1.3333 × π × 729

V = 3053.5517 cm^3

When diameter(d) is reduced to half

d = d/2

Volume (V1) of sphere with diameter 'd' =

V1 = (4/3)π(d/2)^3

Volume (V2) of sphere with diameter 'd' reduced to half, d = d/2, d/2 * 1/2 = d/4

V2 = (4/3)π(d/4)^3

V1 / V2 = [(4/3)π(d/2)^3] / [(4/3)π(d/4)^3]

V1 / V2 = (d/2)^3 / (d/4)^3

V1 / V2 = [d^3 / 2^3] / [d^3 / 4^3]

V1 / V2 = 8 / 64

V1 / V2 = 1 / 8

At the post office, 42% of packages ship priority mail. If 150 packages are shipped today, how many will not go priority mail?

alexdok [17]

(1 - 0.42)*150 = 63

0.58*150 = 87

87 packages were not priority mail.

Any suggestions or answers

The answer is Option A. Because the rate of change is that the tire loses 3 air pressure every hour, it is a constant, making it a linear relationship.

Answer:

-6

Step-by-step explanation:

Some nasty order of operations coming up.

Firstly, deal with that squared:

-12 / 3 * (-8 + 16 - 6) + 2

Simplify the bracket:

-12 / 3 * 2 + 2

Simplify -12 / 3:

-4 * 2 + 2

Simplify -4 * 2:

-8 + 2

Simplify:

-6
