The answer is A because if you cancel out the 3 on the left then you need to do the same with the right, and 18÷3=6. so you keep the inequality sign the same and BAM!!

If y = x3 + 3x2 + 5, what is dy/dx A. 3x2 + 6x + 5 B. 6x2 C. 6x2 D. 3x2 + 6x 
Yanka [14]
You have to use these facts:

1) The derivative of a sum is the sum of the derivatives

2) d[x^n] / dx = n x ^ (n - 1)

3) d [a(f(x) ] / dx = a d [f(x)] / dx

=> d [x^3 + 3x^2 + 5] / dx =  d[x^3]/dx + 3d[x^2]/dx + 0

= 3x^2 + 6x

Answer: option D. 3x^2 + 6x

I need help. I'm desperate. Find the area of the shaded region, round to the nearest tenth. I will give brainliest
Alja [10]

ANSWER

A. (243pi+162) ft^2

EXPLANATION

The area of the shaded region is the sum of the area of the major sector and the area of the isosceles triangle.

Area of major sector

<h3>=\frac{360-90}{360} × \pi × 18^2</h3>

=243\pi ft^2

The area of the isosceles triangle is calculated using the formula;

=\frac{1}{2}r^2sin(0)

<h3>=\frac{1}{2} × 18^2 sin(90)</h3>

=162ft^2

The area of the shaded region

=(243\pi +162)ft^2

The correct answer is A.

Ann [662]

Answer:

It is True.

Step-by-step explanation:

Let's solve the rational equation and if it is ture.

x/8 = 5/4

Cross multiplying, we get

4x = 5*8

4x = 40

Dividing both sides by 4, we get

x = 10.

Therefore, x = 10 is true.


Thank you. :)
