8 0

Answer:

C) 2parts that are one eight each.

Step-by-step explanation:

The reason I chose C) as the correct answer is becasue I evaluated it with the steps below.

A) - 8 parts that are one fourth each.

This cannot be correct because it would surpase the 2/8ths (would be over).

B) - 4 parts that are one-half each.

This cannot be correct because it would surpass the 2/8ths (would be over).

C) - 2parts that are one eight each.

This can be correct because 2 parts have 1/8th. 1/8 + 1/8 = 2/8.

D) - 2parts that are one fourth each.

This cannot be correct because the denominator is not 8, it is 4 meaning it wouldn't fit into the format the question asked for (which was 2/8).

This makes the correct answer C).

I hope this helps you understand and helps you in your question.

\[f(x)=\sqrt{x ^4-16x ^{2}}\]

marusya05 [52]

$f ( x ) = \sqrt{ x^{4} -16 x^{2} }$
a ) The domain:
x^4 - 16 x² ≥ 0
x² ( x² - 16 ) ≥ 0
x² - 16 ≥ 0
x² ≥ 16
x ∈ ( - ∞, - 4 ] ∪ [ 4 , + ∞ )
b ) f ` ( x ) = $\frac{1}{2 \sqrt{x ^{4}-16 x^{2} } } * ( x^{4}-16 x^{2} )` =$
= ( 2 x³ - 16 x ) / √(x^4 - 16 x²)
c ) The slope of the tangent line at x = 5:
f ` ( 5 ) = ( 2 * 125 - 16 * 5 ) / √ ( 625 - 400 ) = 170 / 15 = 34 / 3
The slope of the line normal to the graph at x = 5:
m = - 3 / 34

The given regression shows the relationship between the numbers of car washed(x) and the amount earned for charity(y).

y = 10x + 20

We are to calculate the amount of charity if 50 cars are washed. Number of cars are represented by x, so by substituting x = 50 in above equation we can find the amount of charity that is earned by washing 50 cars.

y = 10(50) + 20 = $ 520

Thus, the charity can earn $520 if 50 cars come in for a wash.

Which of the following equations represents the greatest value of x?

jonny [76]

Hey mate!
You stuck?

^3 The cube root of 125=5
^2 The square root of 35=5.91
^3 The cube root of 64=4
^2 The square root of 38=6.16

Therefore your answer would be x2= 38, because 6.16 is greater than the other sums.

Hope this helps! :) (Don't forget Brainliest) :)
