Answer:
fx = x^4 - 7x^3 + 7x^2 + 21x - 30
the symbol ^ means the power of.
We only know the value of <span>f(5)</span>
therefore we need to figure out what we would put in for x in <span>f(<span>1/3 </span>x)</span> to get 5
set
<span><span>1/3 </span>x=5</span><span>x=15
</span>now if <span>x= 15</span> then <span>f(<span>1/3 </span>x)
= f(<span>1/3</span>×15)
= f(5)=8
</span><span>and so
</span><span><span>1/4</span>×8−2=2−1=1
</span>therefore the "corresponding point" is <span><span>(15,1)</span></span>
The length of the wire is 37.15 ft
<u>Explanation:</u>
The figure is attached for the reference.
tan (71) = 
tan (36) = 
So,
tan(36) (36 + x) = y
tan(71) = 
Substituting x = 12.11 ft in equation 1:
Length of the wire, z = 
So,
Therefore, the length of the wire is 37.15 ft
390, because 10% of 1300 is 130 so 130 times 3 = 390
Answer:
<h2><u><em>
Area = 120 in²</em></u></h2>
<u><em></em></u>
Step-by-step explanation:
follow the formula in the picture
Area = b * h
Area = 15 * 8
Area = 120 in²
