Answer:
-15/4
Step-by-step explanation:
slope = change in y / change in x = (-7 - 8) / (7 - 3) = -15/4
Answer:
8.5 cm
Step-by-step explanation:
Angles of the triangle:
Right triangle as it has 90° angle
Sides are a, b and 19 cm
- sin 30°= a/19 ⇒ a= 19 sin 30°= 19*0.5= 8.5 cm = shortest side
- sin 60°= b/19 ⇒ b= 19 sin 60°= 19*0.866= 16.45 cm
For this case, the first thing to do is to use the equation of the given line.
We have then:
f (x) = 0.76x + 42.39
We substitute the value of x = 15:
f (15) = 0.76 * (15) + 42.39
f (15) = 53.79
Then, subtracting with the original value we have:
53.79-52.04 = 1.75
Answer:
the residual for when x = 15 is:
1.75
Sum of interior angles of polygon
(n-2) × 180 = (5 - 2) x 180 = 3 x 180 = 540
so
2x + 142 + 2x + 3x + 14 + 3x + 14 = 540
10x + 170 = 540
10x = 370
x = 37
m<M = 3x + 14
m<M = 3(37) + 14
m<M = 111 + 14
m<M = 125
