Answer:
350
Step-by-step explanation:
All you have to do is:
Multiply the fraction 7/10 by 500=350
Answer:
y= 5x+10
Step-by-step explanation:
Inverse basically means y is now x and x is now y.
y= x/5 -2 becomes x= y/5 -2
Remember to always leave your equation f(x) = ...
i.e. y =...
x= y/5 -2
add 2 both sides
x+2 = y/5
multiply 5 both sides
5(x+2) = y
Hence,
y= 5x + 10

Answer:
(a) 42.3°
Step-by-step explanation:
Side 'a' is the shortest of three unequal sides, so angle A will be the smallest angle in the triangle. Its measure can be found from the Law of Cosines.
a² = b² +c² -2bc·cos(A)
cos(A) = (b² +c² -a²)/(2bc) = (21² +25² -17²)/(2·21·25) = 777/1050
A = arccos(777/1050) ≈ 42.3°
The measure of angle A is about 42.3°.

<u><em>Additional comment</em></u>
The smallest angle in a triangle can never be greater than 60°. This lets you eliminate choices that exceed that value.
