What is 2x squared plus 5x - 9

1 answer:

7 0

It would be 7x-9 because 2x squared would be 4x, and you can only simplify two numbers if they have the same variable after it. So, all you can do is simplify this equation down to 7x-9.

The radius of a circle is 8 kilometers. What is the area?

Scorpion4ik [409]

Answer:

Area of the circle= $200.96 km^2$

Step-by-step explanation:

Area of a circle= $\pi *r*r$

For radius(r)=8 km

The area of the circle is :

= $\pi *8*8$

As:

$\pi =\frac{22}{7}=3.14$

Area of the circle:

$=3.14*8*8\\\\=3.14*64\\\\=200.96km^2$

The Area of the circle with the radius of $8km$ is $200.96 km^2$

Use this graph of velocity vs. time for two objects to answer the question.

Lynna [10]

Using derivatives, it is found that the correct option is:

A. Object C has an acceleration that is greater than the acceleration for D.

The acceleration is the <u>derivative of the velocity</u>, given by change in velocity divided by change in time, that is:

$a = \frac{\Delta_v}{\Delta_t}$

In this problem:

The change in time for objects C and T is the same.
The <u>change in velocity for object C is greater</u>, thus, it has a greater acceleration, and the correct option is:

A. Object C has an acceleration that is greater than the acceleration for D.
