Answer:

Step-by-step explanation:

Use the cosine ratio, adjacent over hypotenuse. Plug in the values

cos70=x/25.5

Isolate x. Multiply both sides by 25.5

x=25.5*cos70

Answer:

3 * 5 ^ (n-1)

Step-by-step explanation:

3 is the first term and it multiplies by 5

The explicit formula for the geometric sequence is [tex]T_n = 3(5)^{n-1}[/tex]

The standard explicit formula for  a geometric sequence is expressed as:

[tex]T_n = ar^{n-1}\\[/tex]

a is the first term

r is the common ratio

n is the number of terms

Given the sequence of numbers 3, 15, 75, 375...

r = 15/3 = 75/15 = 5

a = 3

Substitute the given parameters into the formula to have:

[tex]T_n = ar^{n-1}\\T_n=3(5)^{n-1}[/tex]

Hence the explicit formula for the geometric sequence is [tex]T_n = 3(5)^{n-1}[/tex]

Answer:

Step-by-step explanation:

Answer:

First step will be option D.

Diameter of the smaller coin will be 2.45 cm

Step-by-step explanation:

Circumference of one coin = 8.03 cm

Circumference of the smaller coin = Circumference of the larger coin - 0.33

                                                         = 8.03 - 0.33

                                                         = 7.7 cm

Circumference of the smaller coin = 2πr = 7.7

r = [tex]\frac{7.7}{2\pi }[/tex]

r = [tex]\frac{7.7\times 7}{2\times 22}[/tex]

r = 1.225 cm

Diameter of the smaller coin = 2 × radius of the smaller coin

                                                = 2 × 1.225

                                                = 2.45 cm

Therefore, first step will be option D.

Diameter of the smaller coin will be 2.45 cm

SA and V of 3x4x5 right rectangular prism.

Three pairs of faces, 3×4, 4×5, 3×5, so area

SA = 2(3×4 + 4×5 + 3×5) = 94 sq ft

V = L×W×H = 3×4×5 = 60 cubic ft

Answer: D.  SA 94 sq ft, V 60 cu ft

2. Right triangular prism, base legs 3x4, height 7

Two triangular faces, combined area 2×(1/2)×3×4=12, and three rectangular faces, 3x7, 4x7 and 5x7

SA = 12 + 7(3+4+5) = 8(12) = 96

Volume is area of base times height, so (1/2)(3)(4)(7)=42.

Answer:  I.  SA 96 sq cm, V 42 cu cm

Answer:

20

Step-by-step explanation:

To find Hypotenuse: Pythagorean Theroem

a^2+ b^2= c^2

The legs are A and B

The side that is directly across from the Right angle is C

12^2 + 16^2 =C^2

144+256=400

400 = c^2

Square root on both sides to get rid of c^2

The square root of 400 is 20

c=20

Answer:

20 feet

Step-by-step explanation:

c =  (a² + b²)

c=  (12^2 + 16^2)

c= square root (400)

c= 20

Answer:

Step-by-step explanation:

The correct statement that Jose is supposed to have written is that  multiply each element in the domain by 5 and subtract 7

Given the linear function written by Jose expressed as f(x) = 5x - 7

Note that the expression is in form of a linear equation y = mx + b where:

x is the input value known as the domain

We are to write the function f(x) = 5x - 7 in words.

Let the domain variable be x

5x means that we are to multiply each element in the domain 5

For 5x - 7, we are to multiply each element in the domain by 5 and subtract 7.

Answer: 140 m3

Step-by-step explanation:

Multiply the area of the trapezoid face by the length .

Since the area is 20, you multiply it by 7 to get 140

Answer:

140 m^3

Step-by-step explanation:

This is a prism with a trapezoid base.

The volume if a prism is

V = (area of base) * height

The base is the trapezoid in the front face. The height is the distance between bases which is 7 m.

area of trapezoid = (b1 + b2)h/2

In the area of the trapezoid, h is the height of the trapezoid which is the distance between parallel bases. It is 4 m in this case.

V = (area of base) * (height of trapezoid)

V = (8 m + 2 m)(4 m)/2 * 7 m

V = 20 m^2 * 7 m^2

V = 140 m^3

Answer:

-8/9 is the answer

Answer:

x=2 is the true solution.

Step-by-step explanation:

We have been given the expression:

2\ln 4x=2\ln 8

Using:

n\ln m=\ln m^n

Our given expression becomes:

\ln{4x}^2=\ln{8^2}

Cancel ln from both sides we get:

4x^2=8^2

On simplification we get:

16x^2=64

x^2=4

Final simplification gives the result:

x=2

Answer:

x = 8

Step-by-step explanation:

2 In x=2 ln 8

Divide by 2

ln x = ln 8

Raise to the e base

e^ ln x = e^ ln 8

x = 8

Answer:

P_1st year   =  P0 x (1 + r/n)               = P0 x (1 + r/n)^1

Answer:

The mean absolute deviation tells you how spread out or how clustered around the mean a set of data is. This is the variation in the data. To compare sets, a higher mean absolute deviation indicates that the data points are more spread out from the mean. A lower mean absolute deviation indicates data points are more clustered around the mean.

Answer:

Sample Answer: The mean absolute deviation tells you how spread out or how clustered around the mean a set of data is. This is the variation in the data. To compare sets, a higher mean absolute deviation indicates that the data points are more spread out from the mean.

[tex]\sqrt{89}[/tex]

Step-by-step explanation:

distance = [tex]\sqrt{(x_{2}- x_{1})^{2} + { (y_{2} - y_{2} } ){^2} }[/tex]

Let:

(x₁ , y₁) = (0 , 5)

(x₂ , y₂) = (8 , 0)

Plug in the corresponding numbers to the corresponding variables:

Remember to follow PEMDAS. Solve the parenthesis first:

distance = [tex]\sqrt{(8- 0)^{2} + { (0 - 5 } ){^2} }[/tex]

distance = [tex]\sqrt{(8)^2 + (-5)^2}[/tex]

Solve for the powers next:

distance = [tex]\sqrt{(8)^2 + (-5)^2}[/tex]

distance = [tex]\sqrt{64 + 25}[/tex]

Simplify:

distance = [tex]\sqrt{64 + 25}[/tex]

distance = [tex]\sqrt{89}[/tex]

Answer:

D

Step-by-step explanation:

Given f(x) then f(x + a) is a horizontal translation of f(x)

• If a > 0 then a shift to the left of a units

• If a < 0 then a shift to the right of a units

Thus

(x - 5)² represents a shift of f(x) to the right of 5 units
