1. Is the graph proportional?

2. How many feet can a sloth travel in 20 minutes?

Answers

Answer:

1. Yes

2. 60

Step-by-step explanation:

The graph is proportional because it passes an origin point.

The equation of the graph is

[tex]y = 3x \: \: (x \geqslant 0) \: \: (y \geqslant 0)[/tex]

We can find the distance when travelling in 20 minutes by substituting x = 20 in the equation.

[tex]y = 3(20) \\ y = 60[/tex]

Therefore the distance (ft) is 60.

Hunter bought a cell phone for $159 and 6% sale tax was added at the register. Hunter gave the cashier nine $20 bills, how much change should he receive?

Answers

Answer:

Step-by-step explanation:

So in order to solve this you would multiply 159 by 6% and get 9.54 so therefore you add the 9.54 to 159 and get 168.24 Then you add together all the bills which is 180 and subtract 180- 168.24 which equals 11.76 so the answer to your question is that Hunter shall received $11.76 in change.

Hey! The answer would be $11.46

149 times 0.06 = 9.54

Yuan makes punch by mixing cranberry juice and pineapple juice.
For every 3 cups of punch, he uses 2 cups of cranberry juice.

Drag the correct number of each type of juice into the box that would make 15 cups of Yuan's punch.

Answers

Answer:

Yuan would have 10 cups of cranberry juice and 5 cups of pineapple juice.

Step-by-step explanation:

For every 3 cups of punch, Yuan has 2 cups of cranberry juice. First, we need to find out how many "batches" of the punch Yuan is making. 3*5=15, so 5 batches. Then we have to find out how much cranberry juice they need. 2*5=10. Then, the pineapple juice. The pineapple juice is the rest of the punch, and 3-2=1. 1*5=5. To check, 10+5=15

A student is standing 20 feet away from the base of a tree. He looks to the top of the tree at a 50° angle
of elevation. His eyes are 5 feet above the ground. Using cos 50° 0.64, what is the height of the tree
to the nearest foot?

36 feet
29 feet
24 feet
31 feet

Answers

Answer:

[tex] \tan(50) =opp(x) \div adh(20) \\ \tan50 \times 20 = opp(h) \\ = 23.8 [/tex]

therefore the answer is 24

The height of the tree is approximately 26 feet.

What are trigonometric identities?

There are three commonly used trigonometric identities.

Sin x = Perpendicular / Hypotenuse

Cosec = Hypotenuse / Perpendicular

Cos x = Base / Hypotenuse

Sec x = Hypotenuse / Base

Tan x = Perpendicular / Base

Cot x = Base / Perpendicular

We have,

Let's denote the height of the tree with 'h'.

Then we can use the trigonometric ratio for cosine as follows:

cos(50°) = adjacent/hypotenuse

cos(50°) = 20/h + 5 (the adjacent side is the distance from the student's eyes to the tree, which is 20 feet, and the hypotenuse is the height of the tree plus the height of the student's eyes, which is h + 5 feet)

Now we can solve for 'h':

0.64 = 20/(h + 5)

0.64(h + 5) = 20

0.64h + 3.2 = 20

0.64h = 16.8

h = 26.25

So the height of the tree is approximately 26 feet (rounded to the nearest foot), which means the closest answer choice is 29 feet.

Therefore,

The height of the tree is approximately 26 feet.

Which function is nonlinear?

Answers

Answer:

Algebraically, linear functions are polynomials with highest exponent equal to 1 or of the form y = c where c is constant. Nonlinear functions are all other functions. An example of a nonlinear function is y = x^2. This is nonlinear because, although it is a polynomial, its highest exponent is 2, not 1.
