Answer:

The answer for M should be 28 because 28 plus 4 is 32 and if you take 5 away from it it will be 27 so M equals 28 ( I hope this helps. )

Joe's grandma lives 36 blocks up the street from Joe. On Saturday, Joe

Kay [80]

Answer:

108 blocks.

Step-by-step explanation:

Joe's grandmother lives 36 blocks away from Joe.

Joe rode two thirds of the way to the house is 2/3 * 36= 24 blocks.

Then he rode back to his house (1 - 2/3) * 36= 12 blocks.

Then Joe rode back to grandma's house= 36 blocks.

Then he rode straight home= 36 blocks.

Total number of blocks he rode is 24+12+36+36= 108 blocks.

A particle moves on a straight line and has acceleration a(t)=24t+2. Its position at time t=0 is s(0)=3 and its velocity at time

user100 [1]

Answer:

It's position at time t = 5 is 593.

Step-by-step explanation:

The velocity v(t) is the integral of the acceleration a(t)

The position s(t) is the integral of the velocity v(t)

We have that:

The acceleration is:

$a(t) = 24t + 2$

Velocity:

$v(t) = \int {a(t)} \, dt = \int {24t + 2} \, dt = 12t^{2} + 2t + K$

K is the initial velocity, that is v(0). Since V(0) = 13, K = 13

Then

$v(t) = 12t^{2} + 2t + 13$

Position:

$s(t) = \int {s(t)} \, dt = \int {12t^{2} + 2t + 13} \, dt = 4t^{3} + t^{2} + 13t + K$

Since s(0) = 3

$s(t) = 4t^{3} + t^{2} + 13t + 3$

What is its position at time t=5?

This is s(5).

$s(t) = 4t^{3} + t^{2} + 13t + 3$

$s(5) = 4*5^{3} + 5^{2} + 13*5 + 3$

$s(5) = 593$

It's position at time t = 5 is 593.

Find the measure of the red arc or chord in ⊙C. The measure of arc XYZ is a °

Igoryamba

The points on the red arc are points A and B

The measure of the red arc is 75 degrees

<h3>How to determine the measure of arc XYZ?</h3>

From the complete question, we have:

Angle DCE = 75 degrees

By vertical angles theorem,

Angle ACB = Angle DCE = 75 degrees

So, we have:

Angle ACB = 75 degrees

The measure of the red arc is the same as the measure of the angle ACB.

So, we have:

Red arc = 75 degrees

Hence, the measure of the red arc is 75 degrees
