Answer:
x = 1/3
Step-by-step explanation:
1 = 1/x -2
add 2 to both sides
3 = 1/x
x = 1/3
Substitute the value of the variable into the expression and simplify 37
Answer:
We conclude that its value change for 277.8$.
Step-by-step explanation:
We know that a perpetuity pays $50 per year and interest rates are 9 percent. We calculate how much would its value change if interest rates decreased to 6 percent. We know that
9%=0.09
6%=0.06
We get
\frac{50}{0.09}=555.5
\frac{50}{0.06}=833.3
Therefore, we get 833.3-555.5=277.8
We conclude that its value change for 277.8$.
Answer:
A) 
Step-by-step explanation:
in a 30-60-90 triangle the sides, respectively, are in the ratio of 1 : : 2
Just substitute it into the gradient formula which is: y2 - y1 / x2 - x1. So 2-3/2-9 = -1/-7 = 1/7
