Answer:

Step-by-step explanation:

Hi there,

In order to solve this expression, you need to substitute x for 1.

You will end up with this expression:

3( $1^{2}$ ) - 2(1) + 1

Now, simplify the expression.

⇒ 3 - 2 + 1

⇒ 1 + 1

⇒ 2

Therefore, the answer when we evaluate the polynomial for x = 1 is 2.

Answer:

A cylinder with a volume of 27 $\pi$ cubic inches and a height of 3 inches

Step-by-step explanation:

Volume of a cylinder = $\pi$ r²h
(where r is the radius and h is the height)

Volume = 27 $\pi$

Height = 3

⇒ 27 $\pi$ = 3 $\pi$ r²

⇒ 9 = r²

⇒ r = √9 = 3

So height = radius

hey, i have this question for algebra nation and i have no clue how to work this problem out... can you please help me?

irina1246 [14]

In algebra the notation is basically just a number, for example, 10, and we take it to the 10th power, you just take the decimal at the end of the 10 and move it 10 spaces to the right, if the number is negative you will move the decimal to the left 10 spaces, the 10th power is a variable and is different with every question

Joe drove 538 miles in 9 hours 15 minutes what was his average speed per hour

DanielleElmas [232]

To calculate any speed, the equation is speed=distance/time
Basically, you first need to take your 9 hours and 15 minutes and combine them into a number with a decimal value.
So, 15*4=60
Sound familiar? Good, because 25*4=100, so they are the same here.
So, we can say 9 hours and 15 minutes is equal to 9.25
Take this now: Speed=538/9.25
You get 58.1621, which you can round to 58.2
This is, of course, your final answer, so Joe drove at 58.16 mph

The first term of a geometric sequence is 6 and the fourth term is 384. What is the sum of the first 10 terms of the correspondi

aleksandrvk [35]

Answer:

2097150

Step-by-step explanation:

GIVEN :-

First term of G.P. = 6
Forth term of G.P. = 384

TO FIND :-

Sum of first 10 terms of the G.P.

CONCEPT TO BE USED IN THIS QUESTION :-

Geometric Progression :-

It's a sequence in which the successive terms have same ratio.

General form of a G.P. ⇒ a , ar , ar² , ar³ , ....... [where a = first term ; r = common ratio between successive terms]

Sum of 'n' terms of a G.P. ⇒ $\frac{a(r^n - 1)}{r-1}$ .

[NOTE :- $\frac{a(1-r^n)}{1-r}$ can also be the formula for "Sum of n terms of G.P." because if you put 'r' there (assuming r > 0) you'll get negative value in both the numerator & denominator from which the negative sign will get cancelled from the numerator & denominator. YOU'LL BE GETTING THE SAME VALUE FROM BOTH THE FORMULAES.]
