How do I solve this question?

Answer:

$f(x) = \frac{108}{7} (\frac{7}{6})^x$ or $f(x) = 15.429(1.167)^x$

Step-by-step explanation:

No need for a calculator.

Assuming that the equation is in the form $y = ab^x$ , we can plug in points to get our equation. For ease, let's use (1,18) and (2,21). When plugging these points in, we get $18 = ab^1, 21 = ab^2$ . Now let's divide the equations to get rid of $a$ : $\frac{21 = ab^2}{18 = ab^1} = \frac{21}{18} = \frac{7}{6} = b$ . Now that we have $b$ , we can plug in the value we just calculated to solve for $a$ : $18 = a(\frac{7}{6} )^1$ , and solving for $a$ , we get $a = \frac{108}{7}$ .

So the $f(x) = (\frac{108}{7})(\frac{7}{6} )^x$

This equation in decimal form (rounded to the nearest thousandth) is $f(x) = 15.429(1.167)^x$ .

hope this helped! :)

Answer:

15/32

10/9 = 1 1/9

26/15 = 1 11/15

Step-by-step explanation:

3/8 / 4/5 = 3/8 * 5/4 = 15/32

8/9 / 4/5 = 8/9 * 5/4 = 40/36 = 10/9 = 1 1/9

2 3/5 / 1 1/2 = 13/5 / 3/2 = 13/5 * 2/3 = 26/15 = 1 11/15

How do i find the radius of a cylinder when only given height and width

mario62 [17]

Step-by-step explanation:

The width of the cylinder might also be the diameter of its circular faces, and half of the diameter is the radius. So, dividing the width by 2 might give you the radius.
