If you think about it, 4x7 is half of 8x7 (If you multiply 4, 7, and 2, you get 8x7). So really you can just multiply 4x7 by 2 and you will get 8x7!
Answer:
the ramp must be lowered
Step-by-step explanation:
Use the definition of the sine function to find the height of a ramp that is 8°.
Sine = Opposite/Hypotenuse
sin(8°) = height/8
height = 8×sin(8°) = 1.11
The height Nate's dad allows is 1.11 feet. At 1.5 feet, the ramp is too high.
The ramp must be lowered.
Answer:
see explanation
Step-by-step explanation:
Using the Pythagorean identity
sin²θ + cos²θ = 1 ( divide terms by sin²θ )
+ 
= 
, that is
1 + cot²θ = cosec²θ ← as required
Answer:
Correct answer: r = 5%
Step-by-step explanation:
Given:
L = 4,500 Loan
t = 4 years time to repay
I = 900 Interest
r = ? simple interest rate
The formula for calculating simple interest is:
I = (L · r · t) / 100
r = ( I · 100) / L · t
r = (900 · 100) / 4,500 · 4 = 90,000 / 18,000 = 5 %
r = 5 %
God is with you!!!
