Answer:

In the increasing order :

The graph is discontinuous at x= -2 and at x=1.

Step-by-step explanation:

We know that the point of discontinuity of a graph is the point where the graph breaks i.e. the graph is not continuous there or in other words we may say that there is a hole in the graph.

From the graph we could observe that the graph is discontinuous at x = -2.
Also the second point of discontinuity is at x = 1.

What slope is perpendicular to m= 5/8<br> m=-5/8<br> m=5/8<br> m=-8/5<br> m=8/5

MrRa [10]

Answer:

C) $m =\frac{-8}{5}$

The slope of the perpendicular line $m =\frac{-8}{5}$

Step-by-step explanation:

<u><em>Explanation:-</em></u>

Given that the slope of the given line is

$m =\frac{5}{8}$

The slope of the perpendicular line

= $\frac{-1}{m}$

The slope of the perpendicular line

= $\frac{-1}{\frac{5}{8} }$

<u><em>Final answer</em></u>

The slope of the perpendicular line

$m =\frac{-8}{5}$

How much principle, to the nearest dollar, should you invest at 4 percent in order to have $3000 for a vacation to Europe in 3 y

KiRa [710]

Answer:

Principle should be $2,667

Step-by-step explanation:

We need $3000 for a vacation to Europe in 3 years.

Using amount formula,

$A=P(1+r)^t$

Where, P is principle (P=?)

A is amount (A=3000)

r is rate of interest (r=0.04)

t is time (t=3)

Substitute the values into formula and solve for P

$3000=P(1+0.04)^3$

$3000=P(1.04)^3$

$P=\frac{3000}{1.04^3}$

$P=2666.98$

$P\approx \$2667$

Hence, Principle should be $2,667

Miguel and Kat are reading the same book. Miguel reads 5 times as many

n200080 [17]

Answer:

$k=\dfrac{m}{5}$

Step-by-step explanation:

Let Kat reads k pages of the book.

Miguel reads 5 times as many pages of the book as Kat. So,

m = 5k ...(1)

Together they read 54 pages. i.e.

m+k = 54 ...(2)

From equation (1),

$k=\dfrac{m}5{}$

Hence, the equation that can be used to find how many pages Kat read is equal to $\dfrac{m}{5}$ .

Please help me with these two, and please explain how to do it. Thank you.

pychu [463]

Answer:

So for number 1 we can use the trigonometry to find out the radius/diameter of the circle then we can use the formula to get the area then we divide by 2 because its half of a circle. So we can get that the cos(68) = 7/x x being the diameter. We then can multiply it by x on both sides. That gives xcos(68) = 7. So then we can do the inverse and get x = cos^-1(68)*7. That gives us approx 18.686 as the diameter, we can divide by 2 and get 9.343. So then we can use the formula which is A = pi*r^2. So that gives us 87.291*pi 274.233. Then if we divide by 2 we get 137.12 that is the answer to first question.

I was able to simplify it into the factored form for number 2.(x-1)^2+(y-2)^2=sqrt(17))^2. Therefore using the circle equation formula we can determine that the center is 1,2. The radius is sqrt(17). We square it and we get 17. So that means that the area is pi*17. Then we get 51.407 as the area.

<h2><u>Answer to 1: 137.12 round to tenth and you get 137.1</u></h2><h2><u></u></h2><h2><u>Answer to 2: </u></h2><h2><u>Center: 1,2 </u></h2><h2><u>Area: 51.407.</u></h2>
