<h3>
Answer: 2880 pounds per square foot</h3>
==========================================================
Explanation:
psi = pounds per square inch
1 foot = 12 inches
1 square foot = 144 square inches
I squared both sides to get the second equation. Think of a 12 by 12 square representing 12 inches along each side, so that leads to 12*12 = 144 square inches being the same as 1 square foot.
That last equation helps us convert from square inches to square feet like so:
Notice in the jump from the second step to the third step, we have the "square inches" unit cancel out when dividing. All that's left is "pounds" up top and "square foot" down below.
In short, we simply multiply by 144 to go from 20 to 2880.
You can do this: since 1/4 is .25 then just multiply 8 x .25
Answer: f (x) = 0.75 minus 0.25x
Step-by-step explanation:
In an arithmetic sequence, the consecutive terms differ by a common difference.
The formula for determining the nth term of an arithmetic sequence is expressed as
an = a1 + (n - 1)d
Where
a1 represents the first term of the sequence.
d represents the common difference.
n represents the number of terms in the sequence.
From the information given,
a1 = 0.5
d = 0.25 - 0.5 = - 0.25
n = 25
The rule for the sequence is
an = 0.5 + (n - 1)-0.25
an = 0.5 - 0.25n + 0.25
an = 0.5 + 0.25 - 0.25n
an = 0.75 - 0.25n
Substituting f(x) for an and x for n, it becomes
f(x) = 0.75 - 0.25x
Well if they look the same if u were to flip or turn it in wat ever position that they are in then if it still looks the same that's how u know that it's congruent
