c=8
Step-by-step explanation:
13-5=c, c=8
Answer:
See below
Step-by-step explanation:
L = length
W = 2 feet less than L = L-2
Area = L x W
20 = L * (L-2)
20 = L^2 - 2L
0 = L^2 - 2L - 20
Use Quadratic Formula a = 1 b = -2 c = -20
L = [-b ± sqrt(b^2-4ac) ]/2a
to calculate <u> L = 5.5826 ft then W = L-2 = 3.5826 ft </u>
Answer: False
Step-by-step explanation:
We can write tan(x) = sin(x)/cos(x)
if cos(x) tends to 1, and sin (x) tends to 0 (this happens aronund the point x = 0)
then we have:
Tan(x) = 0/1 = 0
Then the statement is false, as cos(x) approaches 1 and sin(x) approaches 0, tan(x) also approaches 0.
Answer:
13
Step-by-step explanation:
Odd-numbered terms of the sequence appear to have first differences of 9, 8, 7, ...
Even-numbered terms of the sequence appear to have first differences of 10, 9, 8, ...
Thus the 6th term of the sequence will be 9 more than the 4th term of the sequence. It will be 13.
_____
In the absence of any clue as to the nature of the sequence, you can choose the next term(s) to be anything you like. A rule can always be made that will fit the term values you choose.
Answer:
Correct answer: t₂ = 70 minutes
Step-by-step explanation:
Given:
t₁ = 28 minutes and t₁₂ = 20 minutes, t₂ = ?
The necessary equation for this situation is:
1/t₁ + 1/t₂ = 1/t₁₂ => 1/28 + 1/t₂ = 1/20 => (28 + t₂)/ 28 t₂ = 1/20 =>
28 t₂ = (28 + t₂) · 20 = 20 t₂ + 560 => 28 t₂ - 20 t₂ = 560 =>
8 t₂ = 560 => t₂ = 560/8 = 70 minutes
t₂ = 70 minutes
God is with you!!!
