8. You can graph this or use the summation function on the TI computer.
Answer:
x = 437.3 ft
Step-by-step explanation:
The angle at the top of the triangle = 90° - 29° = 61°
Using the sine ratio in the right triangle
sin61° = 
= 
Multiply both sides by 500
500 × sin61° = x, hence
x ≈ 437.3
Answer:
f(w) = $100 + $15*w
Step-by-step explanation:
The first $100 she deposited remain always the same, they don't change depending on the weeks. What increases along the weeks are the $15.
In the first week she will deposit $15, so she will have $100 + $15 = $115.
On the second week she will deposit $15 more, so she will have $115 + $15 = $130. Another way of writing this is $100 + $15 + $15 = $100 + $15*2.
On the third week she will have $100 + $15 + $15 + $15 = $100 + $15*3.
Therefore, after w weeks, she will have $100 + $15*w.
The function we are looking for is f(w) = $100 + $15*w
Answer:
The answer is a
Step-by-step explanation:
Becuase its right
13x+25=0
13x+25-25=0-25 Since two opposites added give zero, remove them from the expression 13x=-25
