Answer:

58.6 cm;

20.1 m

Step-by-step explanation:

✔️Length of arc = θ/360 × 2πr

Where,

θ = 240°

r = 14 cm

π = 3.14

Plug in the values:

Length of arc = 240/360 × 2 × 3.14 × 14

= 58.6133334 = 58.6 cm (nearest tenth)

✔️Length of arc = θ/360 × 2πr

Where,

θ = 105°

r = 11 m

π = 3.14

Plug in the values:

Length of arc = 105/360 × 2 × 3.14 × 11

= 20.1483334 = 20.1 m (nearest tenth)

If f(x)=2x+3÷2,find f-1(x).

BartSMP [9]

The required inverse function $f^{-1}(x)$ = (2x - 3 ) / 4.

Given that,
f(x) = (2x+3) / 2

To find $f^{-1}(x)$

<h3>What are functions?</h3>

Functions are the relationship between sets of values. e g y=f(x), for every value of x there is its exists in a set of y. x is the independent variable while Y is the dependent variable.

Let f(x) = y
y = (2x + 3) / 2
y * 2 = 2x + 3
2y - 3 = 2x
x = (2y - 3) / 2
Now replace y = x and x = $f^{-1}(x)$
$f^{-1}(x)$ = (2x - 3 ) / 4

Thus, the required inverse function $f^{-1}(x)$ = (2x - 3 ) / 4.

The gas tank in Sharon’s car can hold up to 16.5 gal of gas. About how many liters of gas can the tank hold? 1 L≈1.06 qt

My name is Ann [436]

Most people have trouble deciding on what conversion factor to use. If there you use one conversion factor, and you get something like this:

(gal^2)/qt

Then you know that you used the wrong conversion factor. ALWAYS remember to multiply and divide your units. If you don't, you will not know whether or not you got what you were looking for.
