Answer:

Step-by-step explanation:

General arithmetic sequence formula:

where  = first term, and d = common difference.

The first term is -8

And the common difference appears to be - 7 as 7 is subtracted to get to the next term. Ex. -8 - 7 = -15, -15 - 7 = - 22 and so on.

To get the explicit formula of the sequence we simply plug in the values of a1 and d the general arithmetic sequence formula

General formula:

We have  and d = -7

So the formula to find the nth term would be

Answer:

a_n=-8+(n-1)-7

Step-by-step explanation:

General arithmetic sequence formula: a_n=a_1+(n-1)d

where a_1 = first term, and d = common difference.

The first term is -8

And the common difference appears to be - 7 as 7 is subtracted to get to the next term. Ex. -8 - 7 = -15, -15 - 7 = - 22 and so on.

To get the explicit formula of the sequence we simply plug in the values of a1 and d the general arithmetic sequence formula

General formula: a_n=a_1+(n-1)d

We have a_1=-8 and d = -7

So the formula to find the nth term would be

a_n=-8+(n-1)-7

The diameter of a large lawn ornament in the shape of a sphere is 16 inches. What is the approximate volume of the ornament? Use
Dvinal [7]

Answer: 2143.6\ in.^3

Step-by-step explanation:

Given: The diameter of a large lawn ornament in the shape of a sphere = 16 inches.

Then, the radius of ornament =\frac{16}{2}=8 inches.

We know that the volume of a sphere is given by :-

\text{Volume}=\frac{4}{3}\pi r^3, where r is the radius of a sphere.

Now, the volume of the ornament is given by :-

\text{Volume}=\frac{4}{3}(3.14) (8)^3\\\\\Rightarrow\text{Volume}=\frac{4}{3}\times3.14\times512=2143.57333333\approx2143.6\ in,^3

Hence, the approximate volume of the ornament =2143.6\ in.^3

Jamal deposits $1000 into a savings account on his 18th birthday. If the 2% interest is compounded yearly, how much will he have
dalvyx [7]
The number of years (n) that the deposit stayed in his balance is given by: 65 - 18 = 47 years.

The future value (FV) of a deposit (P), deposited at an interest rate of r% compounded yearly for n years is given by

FV=P(1+r)^n

Given that <span>Jamal deposits P = $1000 into a savings account on for n = 47years at 2% interest compounded yearly, the amount in his bank account at the end of the period is given by

FV=1000(1+0.02)^{47} \\  \\ =1000(1.02)^{47}=1000(2.53634) \\  \\ =\$2,536.34</span>
