No because when you substitute the variable into the equation it doesn’t give you 16

No.

4p - 5 = 16

Isolate the variable and the constant.

4p = 21

p = 21/4

The first term of an arithmetic sequence is -3 and the fifteenth term is 53. What is the common difference of the sequence?

Maru [420]

C: 4 is the right answer

Step-by-step explanation:

Given

a1 = -3

a15 = 53

We know that explicit formula for the arithmetic sequence is:

$a_n=a_1+(n-1)d$

For the 15th, term it will be

$a_{15}=-3+(15-1)d\\53=-3+14d$

Adding 3 on both sides

$53+3 = -3+3 + 14d\\56 = 14d$

Dividing both sides by 14

$\frac{56}{14}=\frac{14d}{14}\\d=4$

Hence,

C: 4 is the right answer

The radius r of a sphere is increasing at a constant rate of 0.04 centimeters per second. (Note: The volume of a sphere with rad

-Dominant- [34]

Answer:

The rate of the volume increase will be $\frac{dV}{dt}=50.27 cm^{3}/s$

Step-by-step explanation:

Let's take the derivative with respect to time on each side of the volume equation.

$\frac{dV}{dt}=4\pi R^{2}\frac{dR}{dt}$

Now, we just need to put all the values on the rate equation.

We know that:

dR/dt is 0.04 cm/s

And we need to know what is dV/dt when R = 10 cm.

Therefore using the equation of the volume rate:

$\frac{dV}{dt}=4\pi 10^{2}0.04$

$\frac{dV}{dt}=50.27 cm^{3}/s$

I hope it helps you!

A box of spaghetti at the grocery store is purchased for $1.60 wholesale and is marked up by 60 percent. Then, the store marks d

Nata [24]

Answer:

the answer is $8.29

Step-by-step explanation:

1.60 marked up by 60% in decimal form is .60

multiply that .60 by 1.60 and you get .64

you add .64 to 1.60 and you get 2.56

you multiply 2.56 by 3 and you get 7.68

you have a 8% sales tax so you multiply 0.08 by 7.68

you will get .61 you add that to 7.68 to get $8.29
