The percentage that describes the original value we are calculating from is 100%

This represents the original value that we are working with.

For example if we are to decrease by 10%, it means we are to be left with 90%

Give the vertex of each function or inequality
f(x)=|x-1|-1

Answers

Answer:

(1,-1)

Step-by-step explanation:

The vertex is the minimum point (in this case). That happens when x - 1 = 0. The reason for that is because the absolute value is going to added to minus 1. The absolute value is always plus.

x - 1 = 0

x - 1+1 = 0 + 1

x = 1

So the minimum point is going to be (1,-1)

You are standing 500 meters from a SpaceXᵗᵐ Rocket that is preparing to take off. The angle of elevation to the top of the rocket is 8o. Find the height of the rocket. Round your answer to the nearest tenth The height of the rocket is meters

Answers

Answer:

70.3m

Step-by-step explanation:

The set up will be a right angled tringle with angle of elevation of 8°.

The distance you are standing from the rocket (adjacent) = 500m

The height of the rocket (opposite) = x

Using the SOH CAH TOA trig identity;

According to TOA

tan(theta) = opp/adj

tan 8 = x/500

x = 500tan8

x = 500(0.1405)

x = 70.27

x = 70.3m (to the nearest tenth)

Hence the height of the rocket in meters is 70.3m

Answers

Step-by-step explanation:

radius of large sphere is R,

then volume is (4/3)*pie*R³

and

the radius of small sphere is r,

then volume is (4/3)*pie*r³

condition is,

volume of larger sphere is twice of the volume of smaller sphere.

then, (4/3)*pie*R³=2*(4/3)*pie*r³;

R³= 2r³
