Answer:

see explanation

Step-by-step explanation:

These are the first 4 terms of a geometric sequence with n th term

$a_{n}$ = a₁ $(r)^{n-1}$

where a₁ is the first term and r the common ratio

r = 36 ÷ 24 = 54 ÷ 36 = 81 ÷ 54 = 1.5 and a₁ = 24, hence

$a_{n}$ = 24 $(1.5)^{n-1}$ ← explicit formula

Help Please . its due in 5 hours and i cant find answers

Answer:

39 pi cubic inches

Step-by-step explanation:

The volume of a cone is (1/3)(area of the base)(height).

$V=\frac{1}{3}Bh$

Find the area of the circular base. The circumference of a circle is $C=2\pi r$ , so

$2\pi r = 6\pi\\\\r=3$

Now that you know the radius of the circular base, you can find its area:

$A=\pi r^2 = \pi(3^2)=9\pi$

The height of the cone is 13. Time to use the volume formula.

$V=\frac{1}{3}Bh\\\\V=\frac{1}{3}(9\pi)(13)\\\\V=39\pi$

Find the slope of the line through each pair of points (11, 18) (20, 12)

JulijaS [17]

Answer:

2/3

Step-by-step explanation:

We can find the slope by using the slope formula

m = ( y2-y1)/(x2-x1)

= ( 12-18)/(20 -11)

= -6/-9

= 2/3

Can I have the answer? I need this done but the topic really confuses me.

labwork [276]

The value of s = 227 degrees. You can determine this because the area of a triangle is always 180 degrees. Since it is s-47, you add 47 to 180. This equals 227. Plug the number in and you get correct answer. 227-47=180

Hope this helps!
