hi
u0 = 64 with u(n+1) = un *0.75
u3 = 64 *0.75^3 = 27
sum is : 64 * ( 0.75^4 -1) / 0.75-1 = 175
manual proof : 64 + 48+36+27 = 175
Step-by-step explanation:

Answer:
12 years
Step-by-step explanation:
every 4 years, olympic occurs.
Every 6 years, senator reelection.
if last year was 2020
in 2024 olympic will occur
in 2026 the reelection will occur
in 2028 olympic will occur
in 2032 olympic and reelection will occur will occur
2032 - 2020 = 12
12 years is the answer
Answer:
D
Step-by-step explanation:
The slope is 2/5 and the slope of the new line will be -5/2 because the negative reciprocal creates a perpendicular line. Use the point-slope form to write the equation, then simplify and convert into the slope intercept form.
(y--2)=-5/2(x-2)
y+2=-5/2x+10/2
y=-5/2x+5-2
y= -5/2x+3
For this problem, we are going to use the <em>law of sines</em>, which states:

In this case, we have an angle and two sides, and we are trying to look for the third side. First, we have to find the angle which corresponds with the second side,
. Then, we can find the third side. Using the law of sines, we can find:

We can use this to solve for
:


Now, we can find
:

Using this, we can find
:


c is approximately 17.5.
