Answer:
decrease by 35%
Step-by-step explanation:
0.65 is only 65% of a whole number, so it decreases the original number by 35%
the general equation for velocity in terms of acceleration and displacement is: v² = v₀² + 2ax.
Solve for a: a = (v² - v₀²)/(2x).
You are given v₀ and v, and x is easy to calculate since you are given its initial and final values. The rest is just arithmetic.
(note also: SI expressions have a required space between the coefficient and the unit symbol. Thus you should have things such as “15 m” and “-2 m·sˉ¹” instead of “15m” and “-2m·sˉ¹”.)
The area of a sector is given by the formula
... A = (1/2)r²·θ . . . . . where r is the radius, and θ is the central angle is radians
Your angle is given in degrees, so we need to multiply it by π/180° to find its equivalent in radians.
... A = (1/2)(7.13 ft)²·(50°)·(π/180°) ≈ 7.0607π ft² ≈ 22.2 ft²
Answer:
Step-by-step explanation:
Line segment DB and line segment AE are medians, then
.
This gives you that 
By the triangle midline theorem,
then
Solve the system of two equations:
Subtract the second equation from the first one:
Then
