Answer:
The square root of 45
Step-by-step explanation:
9^2-6^2=c^2
81-36=c^2
45=c^2
c=sqrt(45)
Answer:
x = 9.5 m
Step-by-step explanation:
Given:
This problem is based on 2D motion kinematics equations:
At maximum height:
Components of initial velocity:
To find time to reach maximum height:
Plugging in the known values:
0 = 4.10 - 9.8t
Total time = 2t = 2(0.418) = 0.836 s
to find horizontal distance covered:
Answer to the example is 1.3 repeating
Step-by-step explanation:
The number we divide by is called the divisor. To divide decimal numbers: Multiply the divisor by as many 10's as necessary until we get a whole number. Remember to multiply the dividend by the same number of 10's.
Answer:
140,150
Step-by-step explanation:
The sum of the angles in a polygon is
180(n−3)
For a pentagon, this equals 540. Since the first 3 angles add up to 240, the remaining 2 angles must add up to 540−240=300∘
The formula for the circumference of the circle is 2πr or πd with r being the radius and d being the diameter. These 2 gives the same result because d=2r
Now because we know that the circumference is 15pi, we just need to reverse to find the diameter.
π*diameter=15*π
We can divide π from both sides.
diameter=15
Hope this helped!
