Answer: y = 4x - 11

Step-by-step explanation:

m = 4 , ( 2,-3 )

y - y1 = m ( x - x1 )

y - (-3) = 4( x - 2 )

y + 3 = 4x - 8

y = 4x - 11

If you deposit $12,500 in an account that pays 4.5% interest quarterly, what is the balance after 8 years? How much did the acco
Masja [62]

In order to determine the balance of the account, use the following formula for the amount of money obtained after t years, basen on a compound interest:

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

where,

P: principal = $12,500

A: amount earnt after t years = ?

r: interest rate in decimal form = 0.045 (4.5%)

n: times at year for the compund interes = 4 (quaterly)

Replace the previous values of the parameters into the formula for A and simplify:

\begin{gathered} A=12,500(1+\frac{0.045}{4})^{4\cdot8} \\ A=12,500(1+0.01125)^{32} \\ A=12,500(1.01125)^{32} \\ A=12,500(1.430451402) \\ A\approx17,880.64 \end{gathered}

Hence, the balance after 8 years is approximately $17,880.64 in the account.

The interest earnt by the account is given by the difference between the previous result and the principal invesment:

I = $17,880.64 - $12,500 = $5,380.64

Hence, the interest earnt is $5,380.64

yulyashka [42]

Answer:

About 91%

Step-by-step explanation:

According to the box plot provided :

Total number of students = 40

Minimum weight = 152 pounds

Third quartile (Q3) = 245

The approximate percentage of students that weigh 245 kg or less

About 10 of the intervals out of the 11 coverage interval of the box plot fall between 152 and 254 ; Hence,

(10 / 11) * 100

90.90

= about 91 % of the total students weigh 245 kg or less

spin [16.1K]

Answer:

A. {–8, –2, 18}

Step-by-step explanation:

y = 5x − 2

x = −1.2 ----> y = 5(−1.2) − 2 = −6 − 2 = −8

x = 0 -----> y = 5(0) − 2 = 0 − 2 = −2

x = 4 -----> y = 5(4) − 2 = 20 − 2 = 18
