The rate of change will be positive and a point in the graph will be (1,250);
the function then would be y = 250x;
after 1 year she will owe USD 5,250;
she will have to make 33 payments.

How to form equation using slope and one point?
y - y1 = m(x - x1) is the equation of a straight line's point slope form, where m is the line's slope and (x1, y1) is the point through which the provided line passes.

Using slope-point equation, the equation for the payment can be taken as:
y-250 = [(500-250)/(2-1)]*(x-1)
y - 250 = 250*(x-1)
y = 250 + 250x - 250 = 250x;
Putting x = 12, for a year the amount paid is USD 3,000.
Amount she owes = USD (8250-3000) = USD 5,250;
Total amount to be paid (in USD) = 8250
Amount paid per month (in USD) = 250
Thus, number of payments required = 8250/250 = 33

Thus, the rate of change will be positive and a point in the graph will be (1,250); the function then would be y = 250x; after 1 year she will owe USD 5,250; she will have to make 33 payments.

Using the following function rule F(x) = 5^x + 5, the value of

Troyanec [42]

Answer:

False

Step-by-step explanation:

Given F(x) = 5^x + 5

To find value of F(-3)

we will plug -3 in place x

then we have

$F(-3) = 5^x + 5\\=>F(-3) = 5^3 + 5 =>F(-3) = 125 + 5\\=>F(-3) = 120$

we have used $5^3 = 5*5*5 = 125$ in the above solution.

It is given that F(-3) is -120 while we have calculated F(-3) to be 120.

Thus, F(-3) is -120 is false.

I need help with this question

Radda [10]

Answer:

2√14m

Step-by-step explanation:

Hypothenus = 9m

Second side = x

third side = 5m

Using Pythagoras theorem

9² = x² + 5²

81 = x² + 25

x² = 81 - 25

x² = 56

x = √56

= √4 × √ 14

= 2√14m

PLEASE HELP kelly invested $1875 in a savings account which earns 3.35% interest compounded quarterly what will the account be w

attashe74 [19]

The account will be worth $2368.20 in 7 years.

The compound interest formula is

$A=p(1+\frac{r}{n})^{n\times t}$

where p is the principal invested, r is the interest rate as a decimal number, n is the number of times the interest is compounded yearly, and t is the amount of time.

3.35% = 3.35/100 = 0.0335.

Using our information, we have:
$A=1875(1+\frac{0.0335}{4})^{4*7}$

which comes out to $2368.20.
