Find the area of the curve y= f(x) = x between x = 5 and x = 10
Tems11 [23]

Answer:

the area of the curve y= f(x) = x between x = 5 and x = 10

A=\frac{75}{2}

Step-by-step explanation:

  • Finding the area of the curve  y = f(x) = x between x = 5 and x = 10

Using the Area formula

A=\int _a^b\:f\left(x\right)dx

As the area of curve lies between x = 5 and x = 10

so

  • a = 5, b = 10

so the integral expression becomes

A=\int _5^{10}xdx

\mathrm{Apply\:the\:Power\:Rule}:\quad \int x^adx=\frac{x^{a+1}}{a+1},\:\quad \:a\ne -1

A=\left[\frac{x^{1+1}}{1+1}\right]^{10}_5

    =\left[\frac{x^2}{2}\right]^{10}_5

     =\frac{1}{2}\left[10^2-5^2\right]

     =\frac{1}{2}\cdot \:75

     =\frac{75}{2}

Therefore, area of the curve y= f(x) = x between x = 5 and x = 10

A=\frac{75}{2}

The lifetime of a battery has the exponential distribution with mean 6.9 months. If it fails, I immediately replace it with anot
irga5000 [103]

Answer:

You should <u>carry 2 other batteries.</u>

Step-by-step explanation:

If the average life of each battery tends to last 6.9 months, and what you need is a year of battery supply, you probably need to carry two batteries.

The battery inside the flashlight has probably already spent much of its half-life.

We are told that the flashlight already has a battery inside, the batteries are discharged inside the flashlight even if the flashlight is not being used.

Which means that the average life of that battery is wearing out.

It would take 2 more batteries in addition to the one already inside the flashlight to supply the need for these for a year.

What is the solution to this inequality?<br>4(2x + 2) + 12 &gt; 100<br>please help!!​
skad [1K]

Subtract 12 from both sides

4(2x + 2) > 100 - 12

Simplify 100 - 12 to 88

4(2x + 2) > 88

Divide both sides by 4

2x + 2 > 88/4

Simplify 88/4 to 22

2x + 2 > 22

Subtract 2 from both sides

2x > 22 - 2

Simplify 22 - 2 to 20

2x > 20

Divide both sides by 2

x > 20/2

Simplify 20/2 to 10

<u>x > 10</u>
