Answer:
x=9.768
y=6.972
Step-by-step explanation:
For this problem we have to use the trig relationships of cos and sin to figure out the lengths. Cos is equal to adjacent/hypotenuse so we can set it as x/r=.814 and since r is equal to 12 we can do 12 times .814 to get x.
We do a similar process for sin but sin is equal to opposite/hypotenuse so we can set up the equation y/r=.581 and we simply multiply both sides by 12 to get 12*.581 to get y.
Also for future reference adjacent and hypotenuse are based on the angle at use, since ∅ is on the bottom left x is the adjacent side and y is the opposite side.
Answer:
1170 m²
Step-by-step explanation:
Parallelogram: 40 x 18 = 720
triangle: (50 x 18) / 2 = 450
total area: 720 + 450 = 1170
Answers:
<u>Question 19:</u> 177 bpm
<u>Question 20:</u> 95˚F
Explanations:
<u>Question 19:</u>
You had the formula set up properly like this:
This is where you went wrong - I don't know exactly what you did, but your division of 4425 ÷ 25 is wrong. You should have ended up with 177 which is the correct answer.
<u>Question 20:
</u>
You had the formula set up correctly again, and merely used the wrong sign when
adding 32.
This is where you went wrong. You subtracted 32 from 63 when you should have added it. (See red circle on your subtraction.)
63 + 32 = 95˚F

so, the interest earned then will be A - 3500.
