Which of the following graphs could be the graph of the function f(x) = x3 + 8?
Gelneren [198K]

It seems you missed to upload graphs given with the question. So i will draw the graph myself then explain the answer.


f(x)=x^3+8 is the given function which is created from parent function f(x)=x^3

Graph of x^3 is like graph of any odd degree function which starts from bottom and goes to top because of positive leading coefficient.

then there is +8 which means parent function is shifted 8 units upward.


You may directly plug some numbers to find points on f(x)=x^3+8 then join those points to get the graph easily.


like we can use numbers x=-2,-1,0,1,2,...

I will show you calculation for x=-2

f(-2)=(-2)^3+8=(-2)(-2)(-2)+8=-8+8=0

Hence first point is (-2,0)

Similarly you can find more points then use them to find the final graph as shown in attached picture.

A car sells for 16000 if the rate of depreciation is %18 find the value of the car after 8 years
marusya05 [52]

Answer:

Hence the sell value of car after 8 years at 8% depreciation = 3270.62 unit  

Step-by-step explanation:

Given as ,

A car initial sells value  = 16000 unit

Depreciation rate of sell = 18 %

Time for depreciation = 8 years

Now , The value of car after 8 years = initial sell value \times (1 - \frac{Rate}{100})^T

Or,                      =  16000 \times (1 - \frac{18}{100})^8

                          =  16000 × 0.2144

                          =  3270.62 unit

Hence the sell value of car after 8 years at 8% depreciation = 3270.62 unit  Answer

please show work. Use a trigonometric function to find the value of x. (Round your answer to the nearest tenth).​
Tatiana [17]

Answer:

x = 12.2

Step-by-step explanation:

sin theta = opp / hypotenuse

sin 55 = 10 /x

Multiply each side by x

x sin 55 = 10

Divide each side by sin 55

x = 10 / sin 55

x =12.20774589

Rounding to the nearest tenth

x = 12.2

Please help me with this I don’t understand it what do ever
dmitriy555 [2]

Answer:

x=3

y=4/3

Step-by-step explanation:

Substitution Method:

Substitute the value of x into the equation

2(6y-5)-3y=2

Solve for y

12y - 10 - 3y= 2

12y - 3y=2 +10

9y=12

y=12/9

y=4/3

Substitute the value of y into the other equation

x=6×(4/3) - 5

Solve for x

x=8-5

x=3
