Answer:

4082

Step-by-step explanation:

Given

The composite object

Required

The volume

The object is a mix of a cone and a hemisphere

Such that:

Cone

[tex]r = 10cm[/tex] ---- radius (r = 20/2)

[tex]h = 19cm[/tex]

Hemisphere

[tex]r=10cm[/tex]

The volume of the cone is:

[tex]V_1 = \frac{1}{3}\pi r^2h[/tex]

[tex]V_1 = \frac{1}{3}\pi * 10^2 * 19[/tex]

[tex]V_1 = \frac{1900}{3}\pi[/tex]

The volume of the hemisphere is:

[tex]V_2 = \frac{2}{3}\pi r^3[/tex]

[tex]V_2 = \frac{2}{3}\pi 10^3[/tex]

[tex]V_2 = \frac{2000}{3}\pi[/tex]

So, the volume of the object is:

[tex]V = V_1 + V_2[/tex]

[tex]V = \frac{1900}{3}\pi + \frac{2000}{3}\pi[/tex]

[tex]V = \frac{3900}{3}\pi[/tex]

[tex]V = 1300\pi[/tex]

[tex]V = 1300 * 3.14[/tex]

[tex]V = 4082[/tex]

Answer:

[tex]C(t) = 85(1.046)^t[/tex], and the correct answer is given by option g.

Step-by-step explanation:

Equation for an concentration increasing exponentially:

The concentration after t years, considering that it increases exponentially, is given by the following equation:

[tex]C(t) = C(0)(1 + r)^t[/tex]

In which C(0) is the initial concentration and r is the growth rate, as a decimal.

The concentration of a pollutant in a lake is 85 parts per million (ppm) and is increasing at a rate of 4.6% each year.

This means that [tex]A(0) = 85, r = 0.046[/tex]. Thus

[tex]C(t) = C(0)(1 + r)^t[/tex]

[tex]C(t) = 85(1 + 0.046)^t[/tex]

[tex]C(t) = 85(1.046)^t[/tex], and the correct answer is given by option g.

Answer:

17,576,000 different license plates are possible.

Step-by-step explanation:

Fundamental counting principle:

States that if there are p ways to do a thing, and q ways to do another thing, and these two things are independent, there are p*q ways to do both things.

In this question:

For each letter, there are 26 possible outcomes.

For each digit, 10 possible outcomes.

So

L - L - L - D - D - D

Number of possible outcomes:

26 - 26 - 26 - 10 - 10 - 10

Each character of the license plate is independent, so, by the fundamental counting principle:

26*26*26*10*10*10 = 17,576,000

17,576,000 different license plates are possible.

Volume of cylinder = 192π inch³

Step-by-step explanation:

Given:

Diameter of base = 8 inch

Length of cylinder = 12 inch

Find:

Volume of cylinder

Computation:

Radius of cylinder = Diameter of base / 2

Radius of cylinder = 8 / 2

Radius of cylinder = 4 inch

Volume of cylinder = πr²h

Volume of cylinder = π(4)²(12)

Volume of cylinder = π(16)(12)

Volume of cylinder = 192π inch³

Step-by-step explanation:

Answer:

angle A=54 degree

angle B =36 degree

Step-by-step explanation:

let angle B be x

angle A=x+18

since they are complementary angles sum of these two angles will be 90 degree

x+x+18=90

2x=90-18

2x=72

x=72/2

x=36 degree

substitute the value of x to find angle A and angle B

for angle A

x+18

36+18

54 degree

for angle B

angle B =x

=36 degree

Future value, A = $10,500

Step-by-step explanation:

Given the following data;

Principal = Rs. 10,000

Interest rate compounded half yearly = 10% = 10/2 = 5%

Time = 1 year

To find the future value, we would use the compound interest formula;

[tex] A = P(1 + \frac{r}{100})^{t}[/tex]

Where;

Substituting into the equation, we have;

[tex] A = 10000(1 + \frac{5}{100})^{1}[/tex]

[tex] A = 10000(1 + 0.05)[/tex]

[tex] A = 10000(1.05)[/tex]

Future value, A = $10,500

Answer:

[tex]A_1 = 12[/tex]

[tex]A_n = A_{n-1} + 3[/tex]

Step-by-step explanation:

Given

[tex]A_n =12+(n-1)3[/tex]

Required

Write as recursive

We have:

[tex]A_n =12+(n-1)3[/tex]

Open bracket

[tex]A_n =12+3n-3[/tex]

[tex]A_n =12-3+3n[/tex]

[tex]A_n =9+3n[/tex]

Calculate few terms

[tex]A_1 =9+3*1 = 9 + 3 = 12[/tex]

[tex]A_2 =9+3*2 = 9 + 6 = 15[/tex]

[tex]A_3 =9+3*3 = 9 + 9 = 18[/tex]

The above shows that the rule is to add 3.

So, we have:

[tex]A_1 = 12[/tex]

[tex]A_n = A_{n-1} + 3[/tex]
