Answer:

Step-by-step explanation:

The domain of a function is the set of input (x-) values for which the function is defined. The range is the set of output (y-) values; often there are limitations.

For example, the sine function y = sin x is defined for all real x; for every input x, there is a corresponding output y. The sine function has a limited range in that the minimum value of the sine is -1 and the max is +1. There is no graph above y = -1 or below y = +1.

. On a school field trip, the school requires that there are 6 teachers for every 90 students. If 135 students attend the trip h

mr_godi [17]

Answer:

For 135 students , the number of teacher requires is 9

Step-by-step explanation:

Given as :

The number of teacher = 6

The number of student = 90

∵ For 90 students , the number of teacher requires = 6

So , For 1 student , the number of teacher requires = $\frac{6}{90}$

= $\frac{1}{15}$

∴ For 135 student , the number of teacher requires = $\frac{1}{15}$ ×135

Or, For 135 student , the number of teacher requires = $\frac{135}{15}$

So, For 135 student , the number of teacher requires = 9

Hence For 135 students , the number of teacher requires is 9 Answer

7 ( x - 12 )= -21 solve for x

marshall27 [118]

Divide botoh sides by 7
x-12=-3
add 12 to both sides
x+12-12=12-3
x+0=9
x=9

Find the value of Y<br> .....

vekshin1

Answer:

$y = 6 \sqrt{3} \: units$

Step-by-step explanation:

In order to find the value of y, first we need to find the length of the perpendicular dropped from one of the vertices of the triangle to its opposite side.

By geometric mean theorem:

Length of the perpendicular

$=\sqrt{9\times 3}$

$=\sqrt{27}\: units$

Next, by Pythagoras theorem:

${y}^{2} = {9}^{2} + {( \sqrt{27} )}^{2} \\ \\ {y}^{2} = 81 + 27 \\ \\ {y}^{2} = 108 \\ \\ y = \sqrt{108} \\ \\ y = \sqrt{36 \times 3} \\ \\ y = \sqrt{ {6}^{2} \times 3} \\ \\ y = 6 \sqrt{3} \: units$

A coin which is tossed straight up into the air. After it is released it moves upward, reaches its highest point and falls back

Helen [10]

Answer:

Answers G, and A

Step-by-step explanation:

the motion of a body is as a result of the various forces acting on it.

As the coin is tossed upwards an upwards force acts on it and this force decreases up to the highest point the coin reaches. at the highest point the force of gravity applies. This force is downwards and constant (9.8m/ $s^{2}$ ).
