Take derivitive of each

f'(x)=9
g'(x)=4
h'(x)=12x

so duh, when x>0.75 then h(x) grows at fastest rate, after that. it just keeps going up

Answer:

\text{Exponential Function: }g(x)=4^x

B is correct.  

Step-by-step explanation:

Given:  

\text{Linear Function: }f(x)=9x+14

\text{Exponential Function: }g(x)=4^x

\text{Quadratic Function: }h(x)=6x^2+1

All the functions are specific function.  

Growth rate of these function. ( If all are in same increasing )

Exponential > Quadratic > Linear  

For increasing value of x

All three functions are increasing function.  

Please see the attachment for graph for grow.

Hence, Exponential function grow fastest rate for increasing value of x is g(x)=4ˣ

Ax-by/c =d solve for x
wolverine [178]
Answer: x = (cd + by) / a

Working out:

(ax - by) / c = d

1)Multiply by c on both sides to get:
ax - by = cd

2) Add by on both sides to get:
ax = cd + by

3) divide by a on both sides to get:
x = (cd + by) / a

Ralph invested in a mutual fund and at the end of 20 years he has $14,300 in his account. If the mutual fund returned an average
Semenov [28]

Answer:

\$5,500

Step-by-step explanation:

we know that

The simple interest formula is equal to

A=P(1+rt)

where

A is the Final Investment Value

P is the Principal amount of money to be invested

r is the rate of interest  

t is Number of Time Periods

in this problem we have

t=20\ years\\ P=?\\ A=\$14,300\\r=8\%=8/100=0.08

substitute in the formula above

14,300=P(1+0.08*20)

14,300=P(2.6)

P=14,300/(2.6)

P=\$5,500

A rectangle has a length that is 2 meters more than the width. The area of the rectangle is 288 square meters. Find the dimensio
Rufina [12.5K]

Answer:

L = 18 and w = 16

Step-by-step explanation:

The area of a rectangle is found by A = l*w. Since the length here is 2 more than the width or 2 + w and the width is w, substitute these values and A = 288 to solve for w.

A = l*w\\288 = w(2+w)\\288 = w^2 + 2w

To solve for w, move 288 to the other side by subtraction. Then factor and solve.

w^2 + 2w  - 288 = 0 \\(w +18)(w-16) = 0\\

Set each factor equal to 0 and solve.

w - 16 = 0 so w = 16

w + 18 = 0 so w = -18

Since w is a side length and length/distance cannot be negative, then w = 16 is the width of the rectangle.

This means the length is 16 + 2 = 18.
