Answer:
15
Step-by-step explanation:
a²+b²=c²
12²+9²= 144+81=225²
√225 = 15
Answer:
$41000
Step-by-step explanation:
If her salary was $1,000 more than the previous year and she save $4,200, $4,200 was 10% of her salary. So we should create an equation. (x being her salary from the previous year)
0.1(x+1000)=4200 (divide 4200 by .01)
x+100=42000
42000-1000= 41000
A) From the function p(t)=6(t), we know that p is 6t, so we plug this into it, to get 3.14 * (6t)^2, or 113.04t^2.
B) Using what we got from A), we plug it in and get 113.04 * 8 * 8, or 7234.56 (Use a calculator on this, or just bash it with pencil and paper).
Csc^2 x = 1 + cot^2 x
so the denominator = csc^2 x
1 / csc^2 x = sin^2 x Answer
Answer:
x = -1.7, or x = -17/10
Step-by-step explanation:
f(x) = 9.2 + 6x + 1 is a linear function and as such (and because the slope is not zero) has only one solution. Combining like terms, we get
f(x) = 10.2 + 6x = 0 (you must set this equal to zero if solving for zero(s).
Then 6x = -10.2, and x = -1.7, or x = -17/10
