Answer:

4a + 4

Step-by-step explanation:

f(x) = x² + 2

f(a) = a² + 2

f(a+2) = (a+2)² + 2

f(a+2) − f(a) = (a+2)² + 2 − (a² + 2)

f(a+2) − f(a) = a² + 4a + 4 + 2 − a² − 2

f(a+2) − f(a) = 4a + 4

Using the formula in model 1, choose the correct answers for the total amount and amount of interest earned in the following com
DIA [1.3K]

The total amount is $ 1015.82 and interest amount is $ 165.82

<em><u>Solution:</u></em>

<em><u>The formula for amount when interest is compounded annually is:</u></em>

\mathrm{A}=P\left(1+r}\right)^{n}

Where,

"A" is the total amount

"P" is the principal

"r" is the rate of interest in decimal form

"n" is the number of years

<em><u>From given, $850 at 2% for 9 years, compounded annually</u></em>

P = 850

t = 9 years

r = 2 \% = \frac{2}{100} = 0.02

<em><u>Substituting the given values we get,</u></em>

A = 850(1+0.02)^9\\\\A = 850 \times 1.02^9\\\\A = 850 \times 1.1950\\\\A = 1015.82

Thus total amount is $ 1015.82

Interest amount = Total amount - principal

Interest amount = 1015.82 - 850

Interest amount = 165.82

Thus total amount earned is $ 1015.82 and interest amount is $ 165.82

elena-s [515]

Answer:

H0: p1=p2    against the claim Ha: p1≠p2

Step-by-step explanation:

Here the proportion of the people going for medical checkup before the program is p1= 0.76

The proportion of the people going for medical checkup after the program is p2= 686/880=0.78

Our null and alternate hypothesis will be

H0: proportion of the people going for medical checkup before the program <u>is equal </u>to the proportion of the people going for medical checkup after the program

against the claim

Ha:  proportion of the people going for medical checkup before the program <u>is not equal </u>to the proportion of the people going for medical checkup after the program

Mathematically this can be written as

H0: p1=p2    against the claim Ha: p1≠p2
