The shadow of a 60 foot pole is a 100 feet long. What is the angle of evaluation from the end of the shadow to the top of the po

Lilit [14]

Answer:

θ = 36.86°

Step-by-step explanation:

Given that,

The shadow of a 60 foot pole is a 100 feet long.

We need to find the angle of elevation from the end of the shadow to the top of the pole.

Height, h = 60 foot

Hypotenuse, H = 100 feet

Using trigonometry to find it.

$\sin\theta=\dfrac{\text{Height}}{\text{Hypotenuse}}\\\\\sin\theta=\dfrac{60}{100}\\\\\theta=\sin^{-1}(\dfrac{60}{100})\\\\\theta=36.86^{\circ}$

So, the angle of elevation is 36.86 degrees.

If a car reaches speeds of 0-100 mph in 0.8 seconds, how many mph will it reach in 1 second?

zvonat [6]

Answer:

125 mph

Step-by-step explanation:

This can be calculated as a simple rule of 3.

In rule of 3 problems, you need to first identify the measures and whether they are direct or inverse to each other.

If they are direct to each other, if one value increases the other will increase too. For example, lets suppose that the Buffalo Bills have won 3 of 4 games. When there are 8 games, then will have won 6, keeping this proportion. Here, the measures are the number of games and the number of Buffalo Bills wins.

Now if they are inverse to each other, if one value increases the other will decrease. For example, if you travel at 60 mph, you will need 6 hours to arrive at your destination. At 80 mph, you will need less time. So, a the average speed increases, the time you need will decrease.

In this case the speeds is proportional to the time. So, if the time increases, the speed will increase too. It can be calculated by the following rule of 3.

Speed Time

100 mph - 0.8 seconds

x mph - 1 second

x = 100/0.8 = 125 mph.

True or false?is the point(16,4) included in this function: Y=2x or Y=x2 or y= x+12 or y=x-12

Gelneren [198K]

Answer:

True

Step-by-step explanation:

It is true because the graph of $y=x-12$ passes through the point $(16,4)$

x = 16

y = 4

Substitute

4 = 16 - 12

4 = 4

Therefore, the answer is true.
