A. 32.08
B. 14.42
C. 9.01
D. 20.05

Answers

Answer:

A. 32.08

Step-by-step explanation:

The figure given is a right triangle. We would apply trigonometric ratios formula to find x.

Reference angle = 58°

Hypotenuse = x

Adjacent length = 17

Thus, we would apply the following:

[tex] Cos(\theta) = \frac{Adjacent}{Hypotenuse} [/tex]

Plug in the values

[tex] Cos(58) = \frac{17}{x} [/tex]

Multiply both sides by x

[tex] Cos(58) \times x = \frac{17}{x} \times x [/tex]

[tex] Cos(58) \times x = 17 [/tex]

Divide both sides by Cos(58)

[tex] \frac{Cos(58) \times x}{Cos(58)} = \frac{17}{Cos(58)} [/tex]

[tex] x = \frac{17}{Cos(58)} [/tex]

[tex] x = 32.08 [/tex] (2 d.p)

Answer:

Step-by-step explanation:

y = csc x

y' = -cot x csc x

[tex] y = \csc \sqrt{x} [/tex]

[tex] y' = \dfrac{d}{dx} [\csc \sqrt{x}] [/tex]

[tex]y' = (-\cot x \csc x) \dfrac{d}{dx} \sqrt{x}[/tex]

What is the value of f(g(1))?

A) 3√2+1
B) 9
C) 0
D) 1

Answers

Answer:

D) 1

Step-by-step explanation:

Given functions f and gf(x) = 3 √x + 1g(x) given as tableTo findf(g(1))Solution

As per table

g(1) = 0

So

f(g(1)) = f(0) = 3√0 + 1 = 0 + 1 = 1f(g(1)) = 1

A teacher asked the class to solve the equation 3(x + 2) = 21. Robert wrote 3x + 6 = 21 as his first step. Which property did he use?

Answers

Answer:

He used the distributive property

Answer:

Robert used the distributive property.

Step-by-step explanation:

3(x + 2) = 21 <------- is the original equation.

3x + 6 = 21   <------- is Robert's first step.

Distributive property is a property that states that multiplying the constant by the numerical values/variables in the parentheses will equal the same as multiplying the consonant by the values added together.

Robert multiplied 3 times "x" and "2." This is the distributive property.

A can manufacturing company is designing a can of cat food to hold 5.5 oz, or about 163 cm3. They have written out that the equation for the surface area for a can with this volume is S=2πr2+163r. Explain why the equation is wrong and how to fix it.

Answers

Answer:

S = 2πr + 326/r

Step-by-step explanation:

Given

Volume = 163cm³

Required

Explain why S = 2πr² + 163r is not correct

The volume (V) of a cylinder is:

V = πr²h ----- (1)

And the surface area (S) is:

S = 2πr² + 2πrh ----- (2)

Make h the subject in (1)

h = V/πr²

Substitute V/πr² for h in (2)

S = 2πr² + 2πr(V/πr²)

Simplify the express in bracket

S = 2πr² + (2πrV)/(πr²)

S = 2πr² + 2V/r

Substitute 163 for V

S = 2πr + 2 * 163/r

S = 2πr + 326/r

The above shows the correct equation that solves the surface area and also shows how it was fixed by substituting proper values and following due process.

A fox can run at a rate of 62 miles in 2 hours. A rabbit can run at a rate of 22 miles in 30 minutes. Which animal has the faster speed in miles per hour?

Answers

Answer:

The rabbit is faster, as it has a speed of 44 mph.

Step-by-step explanation:

Since the fox runs 62 miles in 2 hours, its speed can be determined by dividing the miles traveled by the time it took to do so. Thus, since 62/2 equals 31, its speed was 31 miles per hour.

In turn, the rabbit can travel 22 miles in half an hour. Following the same procedure, since 22 / 0.5 equals 44, its speed is 44 miles per hour.

Therefore, the rabbit is faster than the fox, since it has a speed of 44 mph versus 31 mph for the latter.

What type of angle relationship

Answers

Answer:

they are corresponding angles. hope that helps!

Step-by-step explanation:

Answer:

From the photo we can see that a pair of parallel lines are intersecting one line. BEcause those lines are parallel they form the same angles . Therefore the <1 is equal to the m<5.

A. The relationship between <1 and <5 is that they are congruent meaning they share the same angle measure.

If the m<1 and m<5 are equal then that means the equations of those anlges must also be equal:

3x+7=5x-3

Now we can solve for x

3x+7=5x-3

7=2x+3

10=2x

Answer:

Step-by-step explanation:

Answer:

x= 106

Step-by-step explanation:

The angle opposite 32 is also 32. Considering 44, the missing angle in that triangle would be 104. The angle to the left of 104 would be 76, and if you consider that angle 30 you are left with the measure of 74. X is the angle next to 74, so it makes sense for it to measure 106 because the values must add to 180, and even if it's not drawn to scale 106 looks accurate
