What is the volume of the following figure?
All of the cubes are visible.
A.9 cubic units
B.7 cubic units
C. 10 cubic units
D. 8 cubic units

Answer

f(x) = -9 cos((12(pi) / 7)x) -11

The base equation for a cosine graph is

f(x) = a cos(b(x-c))+d

a = amplitude

b = period

c = phase shift

d = vertical shift

if there's a reflection over the x-axis then there is a negative sign in front of the amplitude

Answer:

Maya is correct. She wrote equivalent fractions with the same denominator and then correctly compared the fractions. Aimee wrote equivalent fractions with the same numerator but did not correctly compare the fractions. Only Maya is correct.

When you're comparing fractions, you have to set them equal to the same denominator, not the same numerator.

Step-by-step explanation:

The equivalent expression of the given expression 50 - 10 - 15 will be 50 + (- 10) + (- 15). Then the correct option is C.

The equivalent is the expressions that are in different forms but are equal to the same value.

The expression is given below.

→ 50 - 10 - 15

Then the expression can be written as

→ 50 + (- 10) + (- 15)

Thus, the correct option is C.

Answer:

10 + 7 + 4 + . . .; n = 5​

The series is arithmetic

Common difference between terms = (-3)

10 - 3 = 7

7 - 3 = 4

Or:

10 + (-3) = 7

7 + (-3) = 4

--------------------------------------------------------------------------

Another example:

Arithmetic:

5, 9, 13, 17

common difference = 4

5 + 4 = 9

9 + 4 = 13

Geometric:

4, 8, 16, 32

4 × 2 = 8

8 × 2 = 16

16 × 2 = 32

common ratio = 2

--------------------------------------------------------------------------

10 + 7 + 4 + . . .; n = 5​

a₁ = 10

a₂ = 7

a₄ = a₃ + d = 4 + (-3) = 4 - 3 = 1     (d = common difference)

a₅ = a₄ - 3 = 1 - 3 = -2

Or with formula:

[tex]d=a_{n} -a_{n-1}[/tex]

d = a₂ - a₁ = 7 - 10 = -3

aₙ = a₁ + (n - 1)d

fourth term = a₄ = 10 + (4 - 1)(-3) = 10 + 3(-3) = 10 + (-9) = 10 - 9 = 1

fifth term = a₅ = 10 + (5 - 1)(-3) = 10 + 4(-3) = 10 + (-12) = 10 - 12 = -2

Sum of the finite series (if n = 5):

[tex]S_{n} =\frac{n(a_{1} +a_{n} )}{2} \\S_{5} =\frac{5(a_{1} +a_{5} )}{2} \\S_{5} =\frac{5(10 +(-2) )}{2} \\S_{5} =\frac{5(8 )}{2} =\frac{40}{2} =20[/tex]

Manual count: S₅ = 10 + 7 + 4 + 1 + (-2) = 20

An expression is defined as a set of numbers, variables, and mathematical operations. The sum of the two polynomial expressions (x² - 5x + 3) + (2x² - 3x - 7) is (3x² - 8x - 4).

In mathematics, an expression is defined as a set of numbers, variables, and mathematical operations formed according to rules dependent on the context.

The sum of the two polynomial expressions are:

(x² - 5x + 3) + (2x² - 3x - 7)

= x² - 5x + 3 + 2x² - 3x - 7

= 3x² - 8x - 4

Hence, The sum of the two polynomial expressions (x² - 5x + 3) + (2x² - 3x - 7) is (3x² - 8x - 4).

Answer:

357.46 meters squared

Step-by-step explanation:

16 x 12.2 x 1/2 = 97.6

12.2 x 10.6 = 64.66

97.6 x 3 = 292.8

292.8 + 64.66 = 357.46

Answer:

  ∠B = 40°

Step-by-step explanation:

The given angle relations can be expressed in two equations.

__

  A + B = 90° . . . . . . . . angles are complementary

  A×(1 -20%) = B . . . . . B is 20% smaller

__

Using the second equation to substitute for B in the first equation, we get ...

  A + 0.80A = 90° . . . . . . substitute for B

  A = 90°/1.8 = 50° . . . . . collect terms, divide by the coefficient of A

  B = A(0.80) = 40° . . . . find B from A

The measure of angle B is 40°.

Answer:

Christine has $18, Kareem has $23, and Trey has $92.

Step-by-step explanation:

This can be solved by using variables to represent the unkown values.

x = Christine's money

x + 5 = Kareem's money.

4(x + 5) = Trey's money.

x + (x + 5) + 4(x + 5) = 133

2x + 5 + 4x + 20 = 133

6x = 108

x = $18

This means that Christine has $18, Kareem has $23, and Trey has $92.

The mean absolute deviation for the data set is 51.5.

The mean is the average value which can be calculated by dividing the sum of observations by the number of observations

Mean = Sum of observations/the number of observations

Median represents the middle value of the given data when arranged in a particular order.

We are given that;

Mean= 59

{419,450,462,499,520,521,589,612}

Now,

Count the number of data values in the set. In this case, n = 8.

Subtract the mean from each data value and take the absolute value. For example:

∣419−509∣=90

∣450−509∣=59

∣462−509∣=47

∣499−509∣=10

∣520−509∣=11

∣521−509∣=12

∣589−509∣=80

∣612−509∣=103

Add up all the absolute differences and divide by n. For example:

MAD=890+59+47+10+11+12+80+103​

MAD=412​/8

MAD=51.5

Therefore, by mean the answer will be 51.5.

Answer:

12^2x = 7^4 = 2401

7^2=12^x

We know that a^x * a^x = a^(x+x) or a^2x

Multiply each side by 12^x

7^2 * 12^x=12^x * 12^x

7^2 * 12^x = 12^(x+x)

Replace 12^x with 7^2 on the left hand side since they are equal

7^2 * 7^2 = 12^ (2x)

7^(2+2) = 12^(2x)
