F’(x)= 1+3 square root x f(9)=68

notka56 [123]

Answer:

$f(x) = x + 2x^\frac{3}{2} + 5$

Step-by-step explanation:

I'm assuming the question here is asking for f(x)

The first step would be to find the antiderivative of f'(x)

$\int{1+3\sqrt{x}} \, dx = \int{1 + 3x^\frac{1}{2}} dx$

Apply the reverse power rule

$x + 2x^\frac{3}{2} + C$

Now solve for C when x = 9

$x + 2x^\frac{3}{2} + C = 68\\9 + 2(9)^\frac{3}{2} + C = 68\\9 + 2(27) + C = 68\\9 + 54 + C = 68\\63 + C = 68\\C = 5$

Now substitute into the antiderivative

$f(x) = x + 2x^\frac{3}{2} + 5$

How many five-digit integers (integers from 10,000 through 99,999) are divisible by 5?

lukranit [14]

Okay to solve this problem you would simply do this solution. It took me a minute, haven't had to do integers in a while. :D

From 10,000 to 99,999 the numbers divisible by 5 ends in 0 or 5.
The first (most significant) digit can be any of nine from 1 to 9.
The 2nd digit can be any of 10.
The 3rd digit can be any of 10.
The 4th digit can be any of 10.
The 5th digit can be either of 2.

<span>That's 9(10)(10)(10)2=18,000

I hope this helps.

Solve 4x − 2(x + 1) = 3x + 10. (5 points)

Dmitry [639]

Answer:

x=-12

Step-by-step explanation:

4x-2x-2=3x+10

2x-2=3x+10

+2 =3x+12

2x=3x+12

-3x=12

-x=12

x=-12

Pls help I don't understand:

sineoko [7]

Answer:

Part a) $T(d)=2d+30$

Part b) $T(6)=42\ minutes$

Step-by-step explanation:

Part a) Write an equation for T (d)

Let

d ----> the number of days

T ---> the time in minutes of the treadmill

we know that

The linear equation in slope intercept form is equal to

$T=md+b$

where

m is the slope or unit rate

b is the y-intercept or initial value

In this problem we have

The slope or unit rate is

$m=2\ \frac{minutes}{day}$

The y-intercept or initial value is

$b=30\ minutes$

substitute

$T(d)=2d+30$

Part b) Find T (6), the minutes he will spend on the treadmill on day 6

For d=6

substitute in the equation and solve for T

$T(6)=2(6)+30$

$T(6)=42\ minutes$
