Answer:
Step-by-step explanation:
It is given that Todd is 30 year old and he perform aerobic activity that may increase his heart beat.
maximum heart beat can be calculated by subtracting the age from 220
For 30 year old male Maximum heart beat
=220-30=190
And during exercise his heart beat increases to 60-90 % of maximum value
60 % of 190=114 beats/min
90 % of 190=171 beats/min
So Heart beat can goes up to 114 - 171 beats/min
Answer:
Answer:
11.02-9.91= 1.11
Step-by-step explanation:
|-11.02| - |-9.91| (First solve in absolute)
11.02 - 9.91 (any values outside absolute becomes positive)
1.11
Step-by-step explanation:
As for the right angle triangle the ratio of opposite side to the hypotenuse side is equal to the sine angle.
The distance of the top of the slide from the ground is 24 foot (to nearest foot). Thus option 3 is the correct option.
<h3>What is right angle triangle?</h3>
A right angle triangle is a triangle in which, one of the angle measures equals to the 9 degrees.
Given information
The angle of depression from top of the slide to the pool is 31. 66°.
The height of the slide is 46 feet.
Image is attached below for the given problem.
As for the right angle triangle the ratio of opposite side to the hypotenuse side is equal to the sine angle.
Thus,

Hence the distance of the top of the slide from the ground is 24 foot (to nearest foot). Thus option 3 is the correct option.

Answer: 
Step-by-step explanation:
Given
The tower is at a height of 
the angle of depression is 
Suppose the surfer is x ft away from the base of the tower

Therefore, the surfer is at a distance of 19.31 ft from the base of the tower.
Answer:
or 
Step-by-step explanation:
You need to complete the square before you can take the square root of both sides.

Subtract 10 from both sides.

To complete the square, you need to add the square of half of the x-term coefficient to both sides.
The x-term coefficient is 7. Half of that is 7/2. Square it to get 49/4. Now we add 49/4 to both sides of the equation.



Now we use the square root property, if
, then
