4. Use Trigonometric Ratios To Solve For The Variable. Show Your Work. Round Lengths To The Nearest Tenth

Answers

Answer 1

Answer:

y = 1.9 units (nearest tenth)

Step-by-step explanation:

recall that for a right triangle with angle θ

tan θ = opposite length / adjacent length

in our case we are given the following:

θ = 15 deg

opposite length = y

adjacent length = 7

substituting these into the equation:

tan θ = opposite length / adjacent length

tan 15 = y / 7

y = 7 tan 15

y = 1.8756

y = 1.9 units (nearest tenth)

Is the domain of the function represented by the data shown in the graph discrete or continuous?​

Answers

9514 1404 393

Answer:

continuousdistance traveled by walking

Step-by-step explanation:

You can draw the graph without lifting your pencil, so it is "continuous."

Rows, drinks, and books are all things that are counted. That is, their number takes on discrete values.

Time, on the other hand, is continuous--able to take on any value.

The graph best models distance as a function of time.

Which graph below represents a function?​

Answers

Draw a vertical line and notice if the vertical line intercepts more than 2 points  in the graph.

A, if we draw a vertical line, it'll just intercept only one point of the graph. So A is function.

A is the only function here. If we draw a vertical line for other graphs, it'll intercept 2 points.

-1.25 or -1 1/4 that’s because the dot is in between a half and a whole number so one half divided by two is 1/4
Answer: -5/4

Explanation: The number marked by the dot is 1.25. To convert decimals to fractions, think of it as a percent. 1.25% is like 125% (out of 100%) so that would be 125/100. Then divide by GCD (greatest common divider). GCD must be a multiple of both 125 and 100. The GCD in this case is 25. So divide numerator (125) and denominator (100) by 25 to get 5/4.

A 7 feet stop sign creates a shadow that is 2 feet long. At the same time a utility pole creates a shadow that is 2 feet long. How tall is the utility pole

Answers

Answer: 7 feets

Step-by-step explanation:

A 7 feet stop sign creates a shadow that is 2 feet long. At the same time a utility pole creates a shadow that is 2 feet long. How tall is the utility pole.

Length of shadow created by 7 feet stop sign = 2 feets

Length of shadow created by utility pole = 2 feets

Length of utility pole =?

Since the length of shadow created by a body is dependent on the height of the body and the position of the sun.

Since the length of shadow are similar = 2 feets

The height of the utility pole and the sign post would be the same.

Hence, height of utility pole will be 7 feets

A hiker begins at sea level and descends 25 feet every minute. How long will it take to get to an elevation of -750 feet?

Answers

Answer:

it would take about 7 1/2 minutes.

Step-by-step explanation:

please give brainliest

Answer:

30 minutes

Step-by-step explanation:

The hiker starts at sea level or 0 feet. He descends 25 feet every minute. This can be written in an equation as so, 0 acting as the starting point, f being feet, and m being minutes:

f = 0 - 25m

This simplifies to:

f = - 25m

We can substitute f in for -750

-750 = - 25m

Now, we divide by - 25 by both sides of the equation

-750 ÷ - 25 = 750 ÷ 25 = 30

30 = m

It would take 30 minutes for the hiker to get to - 750 feet in elevation.

HURRY!! A climber is on a hike. After 2 hours he is at an altitude of 400 feet. After 6 hours he is at an altitude of 700 feet. What is the rate of change.

Answers

Answer:

175ft an hour

Step-by-step explanation: lets say t=hours

so 2t=400ft and 6t=700ft

the difference between hours is 4 because 6-4=2

so we would multiply 4 by ?

to get the missing # you would have to multiple 4 by numbers between 170 and 190 because anything under 170 is no where near 175 and anything above 190 is way off 175. Answer is 175ft per hour

Answer:

total distance =700+400ft

time =2+8 =10hour

rate =distance/time=1100/10=110 ft/hour

since he stops two times

rate of change =110/2=75ft/hour
