Answer: x=2

Step-by-step explanation: f(x) = x + 8

f(x) = 10

10 = x + 8

minus 8 from the both sides

10 - 8 = x

2 = x

x = 2

Supposed charity received a donation of $23.9 million. If this represents 54% of the charity donated funds what is the total amo
Tanzania [10]

Total amount of funds is $44.26 million.

Step-by-step explanation:

Given,

Donation received = $23.9 million

As it represents 54% of charity.

Let,

Total amount = x

Therefore,

54% of x = 23.9 million

\frac{54}{100}*x=23.9\\0.54x=23.9

Dividing both sides by 0.54

\frac{0.54x}{0.54}=\frac{23.9}{0.54}\\x=\$44.26\ millions

Total amount of funds is $44.26 million.

Consider the function f(x)=x3+4x2+2. find the points where the tangent line is horizontal.
lions [1.4K]
Thinking about the graph of f(x), the rate of change is zero whenever there is an extremum.

First, differentiate f(x)

f'(x)=3x^2+8x

Next, find the zeros of f'(x) by factoring.

x(3x+8)=0  \\ x= \frac{-8}{3},x=0

Now, we substitute these x-values into the original equation to find the coordinates.

Greetings from Brasil...

Here we don't have much to go

∛Y = A.(C + 1/X)

∛Y = (AC + A/X)

raising both members to the cube.....

(∛Y)³ = (AC + A/X)³

from Notable Products: (a + b)³ = a³ + 3a²b + 3ab² + b³

Y = (AC)³ + 3(AC)².(A/X) + 3AC(A/X)² + (A/X)³

Y = A³[C³ + (3C²/X) + (3C/X²) + (1/X³)]
