Answer:
<u>x = 6.4</u>
Step-by-step explanation:
Taking the sin ratio of the angle :
- sin 40° = x / 10
- 0.64 = x / 10
- x = 0.64 × 10
- <u>x = 6.4</u>
in general:
if delta>0 the equation has 2 solutions
if delta=0 the equation has 1 solution
if delta<0 the equation doesn't have real solutions
here :
delta=-4n
if n>0=> delta<0 => c) never
Answer: 48 miles
Step-by-step explanation:
From the question, the distance between Franklin City and Williamsville on a map is 3.2 inches and the scale of the map is 1 inch = 15 miles.
The distance between the cities will be to multiply 3.2 by 15 to get the number of miles since 1 inch = 15 miles. This will be:
= 3.2 × 15 miles.
= 48 miles
The distance between Franklin City and Williamsville is 48 miles.

Answer:
3, 7
Step-by-step explanation:
"Zeros" means solutions to the equation f(x) = 0. In other words, what are the values of x that make the function's value equal to zero?
This one can be solved by factoring.
