Answer:

The surface of the given cylinder is 1,099 squared inches.

Step-by-step explanation:

From the given figure ;

Radius of the cylinder = r = 5 inches

Height of the cylinder = h = 30 inches

Surface area of the cylinder = A=2\pi r^2+2\pi rh

A=2\pi r(r+h)

The surface are of the given cylinder in the figure ;

A=2\times 3.14 \times 5 inch\times (5 inch+30 inches)

A=1,099 inches^2

The surface of the given cylinder is 1,099 squared inches.

Find the difference between the terms a10 of an arithmetic sequence and a geometric sequence, both of which
Nady [450]

Answer:-288

Step-by-step explanation:

Given

First term a_0  is common for both AP and GP

For AP

a_2=4=a_0+2d---1

a_4=12=a_0+4d----2

From 1 & 2 we get

d=4

a_0=-4

a_{10} for AP

a_{10}=a_0+10d=-4+10\times 4=36

For GP

4=a_0r^2----3

12=a_0r^4----4

From 3 & 4 we get

3=r^2

r=\sqrt{3}

a_0=\frac{4}{3}

For a_{10}=\frac{4}{3}\times 3^5=324

AP_{a_{10}}-GP_{a_{10}}=36-324=-288

Match each quadratic graph to its respective function
Anna11 [10]

Answer:

f(x) = (x - 3)(x + 1) → Corresponds with the first (raised higher ) ∪ shaped graph

f(x) = -2(x - 1)((x + 3) → Corresponds with the ∩ shaped graph

f(x) = 0.5(x - 6)((x + 2) → Corresponds with the second (lower) ∪ shaped graph

Step-by-step explanation:

For the function f(x) = (x - 3)(x + 1)

We have;

When x = 0, y = -3

When y = 0 x = 3 or -1

Comparing with the graphs, it best suits the first ∪ shaped graph  that rises here than the other ∪ shaped graph

For the function;

f(x) = -2(x - 1)((x + 3)

When x = 0, y = 6

When y = 0, x = 1 or -3

Which corresponds with the ∩ shaped graph

For the function;

f(x) = 2(x + 6)((x - 2)

When x = 0, y = -24

When y = 0, x = -6 or 2

Graph not included

For the function;

f(x) = 0.5(x - 6)((x + 2)

When x = 0, y = -6

When y = 0, x = 6 or -2

Which best suits the second ∪ shaped graph  that is lower than the other (first) ∪ shaped graph

For the function;

f(x) = 0.5(x + 6)((x - 2)

When x = 0, y = -6

When y = 0, x = -6 or 2

Graph not included

For the function;

f(x) = (x + 3)((x - 1)

When x = 0, y = -3

When y = 0, x = -3 or 1

Graph not included

simons monthly take home pay is 2300. if he pays 21% of his gross pay in taxes, what is his gross pay
Mazyrski [523]

Grosspay = 2,300 + .21 * gross pay

.79 * Gross Pay = 2,300

Gross Pay = 2,911.39

********************************************

Double-Check 2,911.39 * .21 = 611.39

2,911.39 - 611.39 = 2,300.00

Correct !!!
