Answer:
2) 92.2km
3) B
4) 4.8m
Step-by-step explanation:
Equation: a² + b² = c²
2)
60² + 70² = c²
3600 + 4900 = c²
8500 = c²
√8500 = c
92.2 = c
3)
12² + 4² = c²
144 + 16 = c²
160 = c²
√160 = c
12.6 = c
4)
4.5² + 1.6² = c²
20.25 + 2.56 = c²
22.81 = c²
√22.81 = c
4.8 = c
Answer:
x=122/3
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
6(x+1)(3)−10=740
18x+18+−10=740(Distribute)
(18x)+(18+−10)=740(Combine Like Terms)
18x+8=740
18x+8=740
Step 2: Subtract 8 from both sides.
18x+8−8=740−8
18x=732
Step 3: Divide both sides by 18.
18x
18

Answer:
(x+1)^2 + (y-3)^2 = 16
Step-by-step explanation:
The equation of a circle is given by
(x-h)^2 + (y-k)^2 = r^2
Where (h,k) is the center and r is the radius
(x--1)^2 + (y-3)^2 = 4^2
(x+1)^2 + (y-3)^2 = 4^2
(x+1)^2 + (y-3)^2 = 16
