lisov135 [29]

Answer:

96, 102

Step-by-step explanation:

We can observe the numbers 72, 78, 84, 90 form an arithmetic sequence with common difference of 6.

It can be continued by adding 6 to the last number:

90 + 6 = 96
96 + 6 = 102

What is the answer for this?

Answer:

Proved

Step-by-step explanation:

Given

$(2 * 10^2) * (3 * 10^5) = 3.5 * 10^7 + 2.5 * 10^7$

Required

Prove

On the right hand side, we have:

$2 * 10^2 * 3 * 10^5 = 3.5 * 10^7 + 2.5 * 10^7$

Rewrite:

$2 * 3* 10^2 * 10^5 = 3.5 * 10^7 + 2.5 * 10^7$

$6* 10^2 * 10^5 = 3.5 * 10^7 + 2.5 * 10^7$

Apply law of indices

$6* 10^{2+5} = 3.5 * 10^7 + 2.5 * 10^7$

$6* 10^7 = 3.5 * 10^7 + 2.5 * 10^7$

Express 6 as 3.5 + 2.5

$(3.5 + 2.5)* 10^7 = 3.5 * 10^7 + 2.5 * 10^7$

Open bracket

$3.5 *10^7+ 2.5*10^7 = 3.5 * 10^7 + 2.5 * 10^7$

You are designing a container in the shape of a cylinder. The radius is 6 inches. You want the container to hold at least 324π c

natta225 [31]

By definition, the volume of a cylinder is given by:

$V =\pi r^2h$

Where,

r: cylinder radius

h: cylinder height

From here, we clear the height.

We have then:

$h = \frac{V}{\pi r^2 }$

Then, replacing values we have:

$h = \frac{324\pi }{\pi 6^2 }$

$h = 9 inches$

Answer:

The least possible height of the container is 9 inches.

Select the functions that have a value of -1. sin180° cos180° tan180° csc180° sec180° cot180°

kupik [55]

We have to break each degree in terms of 90

A) $sin180^\circ=sin(90\times2+0)$

Which is in third quadrant, therefore sine is negative hence

$sin(90\times2+0)= -sin0 ^\circ = 0$

B) $cos180^\circ =cos(90\times2+0)$

Which is in third quadrant, therefore cosine is negative hence

$cos(90\times2+0)= -cos0^\circ = -1$

C) $tan180^\circ=tan(90\times2+0)$

Which is in third quadrant, therefore tangent is positive hence

$tan(90\times2+0)= tan0^\circ = 0$

D) $csc180^\circ=csc(90\times2+0)$

Which is in third quadrant, therefore cosec is negative hence

$cosec(90\times2+0)= -csc0^\circ =$ not defined

E) $sec180^\circ=sec(90\times2+0)$

Which is in third quadrant, therefore secant is negative hence

$sec(90\times2+0)= -sec0^\circ = -1$

F) $cot180^\circ=cot(90\times2+0)$

Which is in third quadrant, therefore tangent is positive hence

$cot(90\times2+0)= cot0^\circ =$ not defined

Hence only $cos 180^\circ$ and

$sec180^\circ$ have value -1

Hope this will help
