H(x)=3x^2+7 h(0) help!

Angelina_Jolie [31]

Answer:

h(0) = 7

Step-by-step explanation:

by saying h(0) it is asking you to plug in 0 as the x value

3(0)^2 = 0

0 + 7 = 7

Find the 61st term of -12, -28, -44,

Citrus2011 [14]

Answer:

$a_{61}=-972$

Step-by-step explanation:

Arithmetic Sequences

The arithmetic sequences are identified because any term n is obtained by adding or subtracting a fixed number to the previous term. That number is called the common difference.

The equation to calculate the nth term of an arithmetic sequence is:

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

Where

an = nth term

a1 = first term

r = common difference

n = number of the term

We are given the first terms of a sequence:

-12, -28, -44,...

Find the common difference by subtracting consecutive terms:

r = -28 - (-12) = -16

r = -44 - (-28) = -16

The first term is a1 = -12. Now we calculate the term n=61:

$a_{61}=-12+(61-1)(-16)$

$a_{61}=-12-60*16=-12-960$

$\mathbf{a_{61}=-972}$

Svetlanka [38]

Answer:

c=8

Step-by-step explanation:

Where do I start when I'm trying to solve a word problem? ... 44=A+B+C=(32C)+3C+C=112C. Multiplying both ends by 211 we find. C=8 ... Mac's collection contain 8 more than twice as many as Ted's.

Leah opens a savings account and deposits $250. She earns interest at a monthly rate of 0.4%. How much money will Leah have in h

PilotLPTM [1.2K]

Answer:

$251

Step-by-step explanation:

To get this amount, we simply find o.4% of 250.

That equals 0.4/100 × 250 = 1.

This means she would have earned an interest amounting to $1 after the first month.

The total amount of money in her account after the first month = 250 + 1 = 251

Hence, she would have an amount of $251 in her account after the first month.

You have a 32-foot fence around a square garden. There are 4 equal sections. You paint 13 of one section of the fence.

xeze [42]

Question:

You have a 32-foot fence around a square garden. There are 4 equal sections. You paint 1/3 of one section of the fence. What fraction of the fence did you paint?

Answer:

The fraction of the fence painted is $\frac{1}{12}$

Solution:

Given that:

You have a 32-foot fence around a square garden. There are 4 equal sections

Find the length of each section:

4 sections = 32 foot

$\text{ 1 section } = 32 \div 4 = 8 foot$

Find the length that is painted:

$\text{ Fence painted }= \frac{1}{3} \text{ of one section }\\\\\text{ Fence painted }= \frac{1}{3} \times 8 = \frac{8}{3} \text{ foot }$

Therefore $\frac{8}{3}$ foot of fence is painted

Find the fraction that that is painted:

Total length of fence = 32

$\text{ Fraction of the fence painted } = \frac{8}{3} \div 32 = \frac{8}{3} \times \frac{1}{32}\\\\\text{ Fraction of the fence painted } = \frac{1}{12}$

Therefore $\frac{1}{12}$ fraction of the fence is painted
