We can check each of these using the Pythagorean Theorem, a^2 + b^2 = c^2
Option A: 
.5^2 + 1.2^2 = 1.3^2


.25 + 1.44 = 1.691.69 = 1.69
This option works
Option B
1^2 + 2^2 = 3^2
1 + 4 = 9
5 ≠ 9
This option does not work, but let's check the others to make sure
Option C:
6^2 + 8^2 = 10^2
36 + 64 = 100
100 = 100
This option works
Option D:
3^2 + 4^2 = 5^2
9 + 16 = 25
25 = 25
This option works

So, after doing the calculations, we see that option B does not work

What is the equation of the rational function g(x) and its corresponding slant asymptote?

The solution to the Questions are

  • The alternate hypothesis demonstrates that there are two possible outcomes for the test.
  • Decision rule: If z > 2.05 or z<-2.05, reject H0
  • z=2.59
  • The two-tailed nature of the test is shown by the alternative hypothesis.
  • The result of the test yields the following P-value: 0.0096

<h3>What is the alternate hypothesis?</h3>

(a)

The alternate hypothesis demonstrates that there are two possible outcomes for the test.

(b)

Here we have

n_{1}=40,\\\\ \bar{x}_{1}=102,\sigma_{1}=5,n_{2}=50,\bar{x}_{2}=99,\sigma_{2}=6

(b)

Here the test is two-tailed. So for \alpha =0.04, the critical values of the z-test are -2.05 and 2.05.

Decision rule: If z > 2.05 or z<-2.05, reject H0

(c)

Test statistics will be

z=\frac{(\bar{x}_{1}-\bar{x}_{2})-(\mu_{1}-\mu_{2})}{\sqrt{\frac{\sigma^{2}_{1}}{n_{1}}+\frac{\sigma^{2}_{2}}{n_{2}}}}  \\\\\\z=\frac{(102-99)-(0)}{\sqrt{\frac{5^{2}}{40}+\frac{6^{2}}{50}}}

z=2.59

(d)

The two-tailed nature of the test is shown by the alternative hypothesis.

(e)

The result of the test yields the following P-value: 0.0096

Description

DescriptionIn mathematics, a zero of a real-, complex-, or generally vector-valued function, is a member of the domain of such that vanishes at; that is, the function attains the value of 0 at, or equivalently, is the solution to the equation. A "zero" of a function is thus an input value that produces an output of

Calculate m∠ADC. Round to the nearest thousandth.
stira [4]

Answer:  54.508^{\circ}

Step-by-step explanation:

Let the angle ADC = x degree

Since, By the given diagram, In triangle BDC,

\frac{BC}{DC} = tan27^{\circ}

⇒ \frac{BC}{19.6} = tan27^{\circ}

⇒ BC = 19.6\times tan 27^{\circ}

⇒  BC = 9.98669881009

Now, In triangle ADC,

tan x =\frac{AC}{DC}

⇒  tan x =\frac{AB+BC}{DC}

⇒  tan x =\frac{17.5+9.98669881009}{19.6}

⇒  tan x =\frac{27.4866988101}{19.6}

⇒  tan x =1.40238259235

⇒  x = 54.508389368\text{ degree} \approx 54.508^{\circ}

I have to find the slope and the y-intersect from these graphs. It would mean alot if someone could help with at least one of th
Sati [7]

Answer:

Alright bear with me, this is gonna be a long one.

<u>The Y INTERCEPT</u>

So the y-intercept is going to be where the line intersects the Y-AXIS. The y-axis is the vertical part of the graph with the numbers on it.

So, for the first one, the line goes through the origin which means that that the y intercept is going to be (0,0)

The next one, the line intersects the y-axis at (0,1)

Here's a tip: the y-intercept will always have 0 as it's x coordinate.

<u>The Slope</u>

Alright, the slope of a vertical line can be found using an equation. Most typically people will describe the slope as RISE/RUN meaning how many units you move up "rise" and how many units you move horizontally "run" to touch the line. Of course, it's easier when you can identify points.

So to make this a little bit easier to understand, I will show you how to use the equation to find the slope.

\frac{y2-y1}{x2-x1}

So for this equation, what you need is two coordinates. So for the first graph, I'm going to use the points (0,0) and (1,3)

\frac{3-0}{1-0}

So we make the three y2 because it's the second y coordinate and the y1 would be 0. Same applies to the x coordinates but use the x values.

the slope for the first graph would be 3/1

<u>FOR THE SECOND GRAPH</u>

\frac{y2-y1}{x2-x1}

Here's our equation now pick two points. I'll be using (-5,4) and (0,1)

\frac{1-4}{0-(-5)}

Don't forget that a negative-a negative = positive

which will leave you with

\frac{-3}{5}

since it can't be simplified any further, your slope is -3/5.

I hope I was able to help you understand this a bit better :)
