$A=2\pi rh$

Data

diameter d= 6.5cm

radius r = $\frac{diameter}{2}$ = $\frac{6.5}{2} = 3.25cm$

height h= 3cm

leteral surface area

$A=2*3.142*3.25*3\\= 61.269\\=61.27cm^2$

Which number line correctly shows 1. 5 + 2. 5? A number line going from 0 to 6. 5 in increments of 0. 5. An arrow goes from 0 to

Usimov [2.4K]

So we want to see which number line shows the sum 1.5 + 2.5. We will see that the correct option is <u>"An arrow goes from 0 to 1. 5 and from 1. 5 to 4"</u>

So the number line usually starts at 0 and goes to the first number, 1.5 in this case.

Then, it moves accordingly to the second number, 2.5 (so it will move 2.5 units to the right)

So the number line should start at 0 and move to the right until it meets 1.5 + 2.5 = 4.

From the options, the only that is correct is:

<u><em>"An arrow goes from 0 to 1. 5 and from 1. 5 to 4"</em></u>

Inverse of y=14x2 show derivations

Rudik [331]

<h2>Answer:</h2>

$f^{-1} (x)=\sqrt{\frac{x}{14}}$ .

<h2>Step-by-step explanation:</h2>

<h3>1. Write the expression.</h3>

$y=14x^2$

<h3>2. Substitute y for x, and x for y.</h3>

$x=14y^{2}$

<h3>3. Solve for y.</h3>

$14y^{2}=x\\ \\y^{2} =\frac{x}{14} \\ \\y=\sqrt{\frac{x}{14}}$

<h3>4. Express your result.</h3>

$f^{-1} (x)=\sqrt{\frac{x}{14}}$ .

He truck is rented at $40 per day plus they charge per mile of use the truck travel 15 miles in one day and the total charge was

Allushta [10]

Answer:

$115 = 15 x + 40$

the charge is $5 dollars per mile

Step-by-step explanation:

He truck is rented at $40 per day plus they charge per mile of use the truck travel 15 miles in one day and the total charge was 115

LEt x be the charge in dollars per hour

Initial charge is 40 and 15 miles travelled in one day

total charge = 15x + 40

Given : total charge is 115

So the equation becomes

$115 = 15 x + 40$

Now we solve for x

Subtract 40 from both sides

$75= 15 x$

Divide both sides by 15

x= 5

so , the charge is $5 dollars per mile
