(4, -1) ---> x = 4 and y = -1

If you look at the graph you can se this

Mark points (0, 2) and (8, -4) in the coordinate plane

Plot the line going through both of these points.

Read the coordinates of the intersection of the line so you can see the solution!

M2/n2 is equivalent to _____.

tankabanditka [31]

Answer:

$\frac{m^2}{n^2}$ is equivalent to $m^2 \cdot n^{-2}$

Step-by-step explanation:

Using exponent rules:

$a^{-n}=\frac{1}{a^n}$

Given the expression:

$\frac{m^2}{n^2}$

⇒ $\frac{m^2}{n^2} = m^2 \cdot \frac{1}{n^2}$

Apply the exponent rule, we have;

$m^2 \cdot n^{-2}$

Therefore, the given expression $\frac{m^2}{n^2}$ is equivalent to $m^2 \cdot n^{-2}$

A company administers an "aptitude test for managers" to aid in selecting new management trainees. Prior experience suggests tha

RoseWind [281]

Answer:

0.94

Step-by-step explanation:

The question after this basically is:

<em>"If the applicant passes the "aptitude test for managers", what is the probability that the applicant will succeed in the management position?"</em>

<em />

So,

P(successful if hired) = 60% = 0.6 [let it be P(x)]

P(success at passing the test) = 85% = 0.85 [let it be P(y)]

P(successful and pass the test) = P(x) + P(y) -[P(x)*P(y)]

So,

P(successful and pass the test) = 0.6 + 0.85 - (0.6*0.85) = 0.94 (94%)

A tile mosaic in the shape of a right triangle is used as the corner for a rectangular pathway. The hypotenuse of the mosaic is

Anit [1.1K]

Answer:

The lengths of the sides are 2.2 ft and 4.5 ft

Step-by-step explanation:

Let

a -----> the length of one side of the mosaic

b ----> the length of the other side of the mosaic

c ----> the hypotenuse of the mosaic

we know that

Applying the Pythagoras Theorem

$c^{2}=a^{2}+b^{2}$ -----> equation A

we have

$a=2b$ -----> equation B

$c=5\ ft$ -----> equation C

substitute equation B and equation C in equation A and solve for b

$5^{2}=(2b)^{2}+b^{2}$

$25=5b^{2}$

$b=\sqrt{5}=2.2\ ft$

Find the value of a

$a=2b$ ------> $a=2\sqrt{5}=4.5\ ft$

therefore

The lengths of the sides are 2.2 ft and 4.5 ft

Sin70cos10-cos70sin10

ololo11 [35]

We know that sin(a-b) = sina.cosb - cosa.sinb

if a=70 & b=10 the sin(70-10) = sin(60) = √3/2

Sin70cos10-cos70sin10 = sin60 = √3/2
