Find f such that f'(x) = 5x² + 9x - 7 and f(0) = 8.
faltersainse [42]

Answer:

\frac{5}{3}x^3+\frac{9}{2}x^2-7x+8\\

Step-by-step explanation:

Integrate your function with respect to x to get the non-differentiated form.

\int(5x^2+9x-7)dx=\frac{5}{3}x^3+\frac{9}{2}x^2-7x+c\\

Plug in your known value of x to get your value for your constant

f(0) = 8\\ \frac{5}{3}(0^3)+\frac{9}{2}(0^2)-7(0)+c = 8 \\c=8

This gives you your function to be

\frac{5}{3}x^3+\frac{9}{2}x^2-7x+8\\

Can a set of data having two modes have two points of central tendency
Fynjy0 [20]

Answer:

The  Measure of Central Tendency are

1. Mean

2. Median and Quartiles

3. Mode

4. Geometric Mean

5. Harmonic Mean

→When all the five Measure of Dispersion are Same, it means the two data sets have Identical Variate.

→Now consider the two data sets,

A=3,4,4,5

B=1,4,4,7

Both the Data set have , same mean, median, and Mode,which is equal to 4.

→When you will consider, First three as Measure of central tendency ,then it becomes incorrect statement ,that Data Set are same.

Write the equation of the line passing through the points (-4,-7) and (8,-13)
posledela

Answer:

y=-1/2x-9

Step-by-step explanation:

First, solve for the slope, m.

m= y2-y2/x2-x1

m= -13-(-7)/8-(-4)

m= -6/12

m= -1/2

Plug in the slope into the formula y=mx+b.

y= -1/2x + b

-7= -1/2(-4) + b

-7= 2 + b

(subtract 2 from both sides)

-7-2 = b

-9 = b

FINAL ANSWER:

y=-1/2x+-9

<u>y=-1/2x - 9</u>
