Answer:

The box to the left will have the equation p(x) = 5x² and the box to the right will have the equation n(x) = $\frac{1}{5} x^{2}$

Step-by-step explanation:

The coefficient of the x² decides how wide or narrow a quadratic graph is. If the coefficient is a fraction of 1, the smaller the fraction the wider the graph gets. If the coefficient is a number bigger than 1, the bigger the number, the narrower the graph gets.

Emma puts $1000 in a savings account that pays 4% interest, compounded monthly. How much money will be in the account 3 years la

lorasvet [3.4K]

Answer:

Option A. $\$1,127.27$

Step-by-step explanation:

we know that

The compound interest formula is equal to

$A=P(1+\frac{r}{n})^{nt}$

where

A is the Final Investment Value

P is the Principal amount of money to be invested

r is the rate of interest in decimal

t is Number of Time Periods

n is the number of times interest is compounded per year

in this problem we have

$t=3\ years\\ P=\$1,000\\ r=0.04\\n=12$

substitute in the formula above

$A=\$1,000(1+\frac{0.04}{12})^{12*3}=\$1,127.27$

Hello!

So, the slope is 2, which means "up 2 over 1" because of rise over run and 2 is 2/1.

You have to find the graph that as a line passing through (-2, -3), so the answer is going to be Graph D.

Hope this helps :))

Write and solve a word problem that can be modeled by addition of two negative numbers integers

777dan777 [17]

<span>A word problem that can be modeled by addition of two negative numbers integers is given as followed.

Evans and Irvin are standing at the same spot. Evans took 7 steps backwards and another 7 steps backward, what is the current position of Evans relative to where Irvin is standing?

To solve the above, we note that Evans </span><span>took 7 steps backwards and another 7 steps backward, thus his current position relative to Irvin is given by (-7) + (-7) = -7 - 7 = -14.

Therefore, Evans is 14 steps backwards relative to where Irvin is standing.

Julie invested 3000 in a simple interest account for 2 years. At the end of the 2 years, she had earned $75 in interest. What wa

Dahasolnce [82]

The simple interest rate was: 1.25%

Step-by-step explanation:

Simple interest is given by:

$A = Prt\\Here\\A => Interest\\P=>Principal\ Amount\\r => Rate\\t => Time\ in\ years$

Given

Principal amount =$3000

Time = t = 2 years

Interest amount = A = $75

putting the values in the formula

$75 = 3000 * r * 2\\75 = 6000r$

Dividing both sides by 6000

$\frac{6000r}{6000} = \frac{75}{6000}\\r = 0.0125\\$

So,

The rate is:

0.0125 * 100 = 1.25%

Hence,

the simple interest rate was: 1.25%
