A cylinder has a base radius of 7in and a height of 3in. What is its volume in cubic in,
to the nearest tenths place?

Answer:

s(x)

Step-by-step explanation:

s(x) is a linear function, so the average rate of change is its slope.

Its slope is 3.

You are correct.

To find the average rate of change of polynomial function t(x) from -2 to 2, find the values of t(x) at x = -2 and at x = 2.

average rate of change = [t(2) - t(-2)]/[2 - (-2)]

t(x) = 0.1(x^3 - x^2 + 2)

t(-2) = 0.1[(-2)^3 - (-2)^2 + 2)]

t(-2) = 0.1(-8 - 4 + 2)

t(-2) = -1

t(2) = 0.1[(2)^3 - (2)^2 + 2)]

t(2) = 0.1(8 - 4 + 2)

t(2) = 0.6

average rate of change = [t(2) - t(-2)]/[2 - (-2)]

average rate of change = [0.6 - (-1)]/4

average rate of change = 1.6/4

average rate of change = 0.4

average rate of change for s(x) = 3

average rate of change for s(x) = 0.4

Answer: s(x)

Answer:

a = 15, b = -14

Step-by-step explanation:

From the question,

a/5 - b/2 = 10

Multiply all through by 10

(a/5)10 - (b/2)10 = 10×10

2a - 5b = 100...................... Equation 1

a - b = 29 ........................ Equation 2

Solving equation(1 ) and equation (2) simultaneously

using elimination  method,

multiply equation (2) by 2.

2a - 2b = 58.................... Equation 3

Substract equation 3 from equation 1

2a - 2a -5b-(-2b) = 100-58

0 - 5b+2b = 42

-3b = 42

b = 42/-3

b = -14.

Substitute the value of b into equation 2

a - (-14) = 29

a +14 = 29

collect like terms

a = 29-14

a = 15.

Hence, a = 15, b =-14

Answer:

When there is no width, the area is 0m²

Step-by-step explanation:

Expressing the area of a rectangle as a function of its width:

Area of a rectangle = Length * width

Since the area of rectangle is related to the width by the multiplication operatkr. We can conclude from the options given that ; if the value of width = 0 ; the the area of rectangular plot = 0

When x :

Area = Length * width

Area = Length * 0

Area = 0

Area = Length * 0

Aea = 0

Answer:

90 - 37 will give a solid 53

Step-by-step explanation:

the two sums of A to C to C to B so 22.9(C, B) and 14.1 (A, C)

and know that this angle is 90 degrees, my guess would be to subtract the to given numbers with degrees to earn the sum so 22.9 + 14.1 equals 37

now we add angle degrees and sum and subtract one another,

90 - 37

$12,741.4

Step-by-step explanation:

Answer:

Step-by-step explanation:

y = mx +b

m- Slope ; b - y-intercept

1) y = 2x + 5

Slope = 2

y-intercept = 5

2) 2y = 4x - 5

 Divide the equation by 2

[tex]\frac{2y}{2}=\frac{4x}{2}-\frac{5}{2}\\\\y = 2x - \frac{5}{2}[/tex]

Slope = 2

y-intercept = [tex]\frac{-5}{2}[/tex]

3) 3x + 6y = 8

           6y = -3x + 8

            [tex]\frac{6y}{6}=\frac{-3x}{6}+\frac{8}{6}\\\\ y = \frac{-1}{2}x+\frac{4}{3}\\\[/tex]

Slope = -1/2

y-intercept = 4/3

Answer:

square with sides of 6 in

Step-by-step explanation:

Tessellation is the arrangement of shapes in repeated patterns without gaps or overlapping.

Tessellation is usually done with regular polygons. Only three regular shapes can tessellate, these are equilateral triangle, regular square and regular hexagon. For other polygon to tessellate, more than one shape must be used. A octagon can be used to make tessellations if it is used together with a square.

Mark uses tiles with shape of octagon of sides 6 in. To fill the gaps, Mark have to uses a square with sides of 6 in

Answer:

-86x^2 -2x - 8

Step-by-step explanation:

The solution is:

6x²+2x²+3x-4x-9+1  becomes 8x²- x -8.

Subtraction is the process of taking away a number from another. It is a primary arithmetic operation that is denoted by a subtraction symbol (-) and is the method of calculating the difference between two numbers.

Here, we have,

Subtract -2x^2+4x-1 ( minus 2x squared plus 4x minus 1) from 6x^2+3x-9 (6x squared plus 3x minus 9).

To  subtract -2x^2+4x-1 from 6x^2+3x-9,

that is

6x^2+3x-9 - (-2x^2+4x-1).

This can be written as

6x²+3x-9 - (-2x²+4x-1)

Now, opening the bracket, we will get

6x²+3x-9 +2x²-4x+1

Then, collecting like terms, we get

6x²+2x²+3x-4x-9+1

6x²+2x² = 8x²

3x-4x = -x

-9+1 = -8

∴6x²+2x²+3x-4x-9+1  becomes 8x²-x -8

The answer is 8x²-x -8.

Answer:

127.5

Step-by-step explanation:

First, we need to find the value of x

since the two angles are connected to a straight line, their sum will be 180 (degrees)

[tex](2x+7)+(6x-9)=180^{o}[/tex]

add the angles together

[tex]\therefore 8x-2=180[/tex]

add 2 to both sides

[tex]\therefore 8x=182[/tex]

divide out by 8

[tex]\therefore x = 22.75[/tex]

now we must determine which angle has the greater value (not visually)

[tex]angle A = 2x+7[/tex]

[tex]\therefore \angle{A} = 2(22.75)+7[/tex]

[tex]\therefore \angle{A} = 45.5+7[/tex]

[tex]\therefore \angle{A} = 52.5[/tex]

[tex]angle B = 6x-9[/tex]

[tex]\therefore \angle{B} = 6(22.75)-9[/tex]

[tex]\therefore \angle{B} = 136.5-9[/tex]

[tex]\therefore \angle{B} = 127.5[/tex]

[tex]\angle{B}>\angle{A}\ \because\ 127.5>52.5[/tex]

so the answer would be 127.5

Answer:

Mika's estimated the sum to be 216. The actual sum is 216.27

Step-by-step explanation:

Mika:

189.27 = 189

15.8 = 16

11.2 = 11

189 + 16 + 11 = 216

Actual:

189.27 + 15.8 + 11.2 = 216.27

Answer:

The equation in standard form is [tex](x + 1)^{2} + (y - 10)^{2} = 4[/tex]

Step-by-step explanation:

The distance from (-1, 12) to (-1, 8) = 4 = diameter of the circle.  So, 2 = radius

The center of the circle is at (-1, 10)

The equation in standard form is [tex](x + 1)^{2} + (y - 10)^{2} = 4[/tex]
