Answer:
1. measure of angle E is 90 degrees
2. Measure of angle F + measure of angle G is 90 degrees
Step-by-step explanation:
Angle E is 90 degrees because it is marked as a right angle (the square)
A triangle has 180 degrees so if E is 90 degrees then the other 2 also have to equal 90 degrees
F(x) = 20000 (1-0.15) power x
So
f(x) = 20000 (0.85) power x
3x(4x4 – 5x)
= 12x^5-15x^2
Answer:
Yes
Step-by-step explanation:
using pythagorus theorum: a^{2} + b^{2} = c^{2}
24^{2} +32^{2} = 1024+576
= 1600
40^{2} = 1600
thus, it can be concluded that these lengths can be the sides of a right-angled triangle.
Answer:
Ans= 6720 ways
Step-by-step explanation:
From Combination rule from Permutation and Combination, nCr
We use 8^C3 or 8C3,
8x7x6x5x4x3x2x1
-------------------------- =6,720
3x2x1
or
8x7x6x5x4x3! /3!, here the 3! cancels each other out, and we're left with 8x7x6x5x4, which equals 6720.
