Answer:
See below
Step-by-step explanation:
we have f(x) = -(x-7) + 3
and we want to find f(4)
essentially, f(4) means that the input is 4 and to find the output we plug in the value of the input where ever x is and evaluate.
So for f(x) = -(x-7) + 3
To find f(4) we replace all x's with 4
f(4) = -(4-7) + 3
we now evaluate
==> subtract 7 from 4
f(4) = -(-3) + 3
==> apply two negative rule ( basically if there are two negative signs they cancel out and the number turn positive )
f(4) = 3 + 3
==> add 3 and 3
f(4) = 6

Step-by-step explanation:
Answer: Jacob's second jump was 6 1/3 feet
Step-by-step explanation:
On his first jump, he jumped 7 2/3
feet. We would convert each mixed fraction to improper fraction
to enable easy addition and subtraction. Converting 7 2/3 feet to improper fraction, it becomes 23/3 feet.
His second jump was 1 1/3 feet shorter. Converting 1 1/3 feet to improper fraction, it becomes 4/3 feet.
Therefore, the distance that Jacob covered on his second jump would be
23/3 - 4/3 = 19/3 feet
Converting 19/3 feet back to mixed fraction, it becomes
6 1/3 feet

EXPLANATION
This is a Circle Theorem .
The angle created by an arc at the center of a circle is twice the angle created at the circumference by the same arc.
This implies that
