Answer:

Angle of elevation = 21.167°

Step-by-step explanation:

Given:

Horizontal distance cover by rover = 180 m

Vertical distance cover by rover = 65 m

Find:

Angle of elevation

Computation:

Using trigonometry function;

Sin θ = Perpendicular / Hypotenuse

⇒ Sin θ = Vertical distance cover by rover / Horizontal distance cover by rover

⇒ Sin θ = 65 / 180

⇒ Sin θ = 0.3611

⇒ Sin⁻¹ (0.3611) = 21.167°

Angle of elevation = 21.167°

Answer:

[tex]surface \: a = 9 \times 5 \\ = 45ft \times 2 \\ = {90}^{2} ft\\ surface \: b = \frac{1}{2} bh \\ = \frac{1}{2 } \times 6 \times 4 \\ = 3 \times 4 \\ = 12 \times 2 \\ = {144}^{2} ft \\ = 90 + 144 \\ = {234}^{2} ft[/tex]

Answer:

[tex]\sin(30)[/tex]

Step-by-step explanation:

Given

[tex]\sin(23) \cos(7) + \cos(23) \sin(7)[/tex]

Required

An equivalent expression

The above is an illustration of the sine formula which states:

[tex]\sin(A) \cos(B) + \cos(A) \sin(B) = \sin(A + B)[/tex]

In this case:

[tex]A = 23\\ B = 7[/tex]

So:

[tex]\sin(23) \cos(7) + \cos(23) \sin(7) = \sin(23 + 7)[/tex]

[tex]\sin(23) \cos(7) + \cos(23) \sin(7) = \sin(30)[/tex]

Hence, an equivalent expression is: [tex]\sin(30)[/tex]

Answer:

whats the question

Step-by-step explanation:

Answer:

60 degrees

Step-by-step explanation:

All angles of a triangle will add up to equal 180 degrees.

Set up an equation to solve for x:

9x - 3 + 50 + 9x + 7 = 180

Combine like terms

18x + 47 + 7 = 180

18x + 54 = 180

Subtract 54 from both sides

18x = 126

Divide both sides by 18

x = 7

Now plug in 7 for x in the expression for angle A:

9(7) - 3

63 - 3

60

Check work:

60 + 50 + 9(7) + 7 = 180

110 + 63 + 7 = 180

173 + 7 = 180

180 = 180

Correct

Answer:

A  ≈ 35.3 units²

Step-by-step explanation:

Calculate the radius CB using Pythagoras' identity in the right triangle.

CB² + AB² = AC²

CB² + 6² = 9²

CB² + 36 = 81 ( subtract 36 from both sides )

CB²  = 45 = r²

Then area of quarter circle is

A = [tex]\frac{1}{4}[/tex] × πr² = [tex]\frac{1}{4}[/tex] × π × 45 ≈ 35.3

Answer:

c = 36.06

Step-by-step explanation:

a² + b² = c²

20² + 30² = c²

400 + 900 = c²

c² = 1300

[tex]\sqrt{c^2} =\sqrt{1300}[/tex]

c = 36.06

Answer:

[tex](f\ o\ g)(x) = 3x[/tex]

[tex]-\infty < x < \infty[/tex]

Step-by-step explanation:

See comment for right presentation of question

Given

[tex]f(x) = ln(x^2)[/tex]

[tex]g(x)=\sqrt{e^{3x}}[/tex]

Solving (a): (f o g)(x)

This is calculated as:

[tex](f\ o\ g)(x) = f(g(x))[/tex]

We have:

[tex]f(x) = ln(x^2)[/tex]

[tex]f(g(x)) = \ln((g(x))^2)[/tex]

Substitute: [tex]g(x)=\sqrt{e^{3x}}[/tex]

[tex]f(g(x)) = \ln(\sqrt{e^{3x}})^2[/tex]

Evaluate the square

[tex]f(g(x)) = \ln(e^{3x})[/tex]

Using laws of natural logarithm:

[tex]\ln(e^{ax}) = ax[/tex]

So:

[tex]f(g(x)) = \ln(e^{3x})[/tex]

[tex]f(g(x)) = 3x[/tex]

Hence:

[tex](f\ o\ g)(x) = 3x[/tex]

Solving (b): The domain

We have:

[tex]f(g(x)) = 3x[/tex]

The above function has does not have any undefined points and domain constraints.

Hence, the domain is: [tex]-\infty < x < \infty[/tex]

Answer:

Area = 31.5 units²

Step-by-step explanation:

Area of the triangle = ½ × base × height

base = 9

height = 7

Substitute

Area = ½ × 9 × 7

Area = ½ × 63

Area = 31.5 units²

Answer:

150 kg

Step-by-step explanation:

here is the complete question

A rectangular gate is made using 6 straight pieces of steel.

5 m

12 m

The weight of the steel is 2.5 kg per metre.

Work out the total weight of the steel gate.

To solve this question determine the square root of 12 and 5

√169 = 13

5 + 12+ 5 + 12+ 13 + 13 = 60 m

total weight = 60 x 2.5 = 150kg

Answer:

C. They are equal

Step-by-step explanation:

Both have the same volume 24

Both Figure have same Volume.

Every three-dimensional item requires some amount of space. The volume of this space is measured. Volume is defined as the space occupied by an object inside the confines of three-dimensional space. It is also known as the object's capacity.

We have,

Cone:

Volume of Cone = 1/3 πr²h

                            = 1/3 (3.14)(3)²8

                            = 75.36 unit³

Cylinder:

Volume of Cylinder = πr²h

                                = (3.14)(2)²6

                                = 75.36 unit³

Thus, Both figures have Equal volume.
