In the coordinate plane, the points A (7, 5), B(-10, -9), and C(4, - 11) are reflected over the x-axis to the points A, B', and C', respectively. What are
the coordinates of A', B', and C'?

Answer:

student A: the third step, they subtracted 16 squared from 24 squared, without figuring out what the squared values were.

student B: is correct

student C: step four, they didn't find the square root of 320, they kind of just took the square off of b and called it good.

Step-by-step explanation:

Your calculator can do this, but it's probably faster to do it in your head.

  [tex]\left|\begin{array}{cc}a&b\\c&d\end{array}\right|=ad-cb[/tex]

__

  [tex]\left|\begin{array}{cc}3&-1\\-3&4\end{array}\right|=(3)(4)-(-3)(-1)=9\\\\ \\\left|\begin{array}{cc}8&-1\\-4&-1\end{array}\right|=(8)(-1)-(-4)(-1)=-12[/tex]

And the next two rows are ...

  (-12)(5) -(12)(-1) = -48   —   (2)(-1) -(2)(-1) = 0

  (0)(4) -(17)(-1) = 17   —   (1)(1) -(0)(0) = 1

Answer:

The (x1, y1) and (x2, y2) can be switched in the Distance Formula.

Given:

M=-5 and (-3,-2).

To find:

The equation in the form [tex]y=mx+b[/tex].

Solution:

The slope intercept form of a line is

[tex]y=mx+b[/tex]          ...(i)

where, m is slope and b is y-intercept.

We have m=-5. Putting m=-5 in (i), we get

[tex]y=-5x+b[/tex]          ...(ii)

We have a point (-3,-2). Putting x=-3 and y=-2 in (ii), we get

[tex]-2=-5(-3)+b[/tex]

[tex]-2=15+b[/tex]

[tex]-2-15=b[/tex]

[tex]-17=b[/tex]

So, the value of b is -17.

Putting b=-17 in (ii), we get

[tex]y=-5x+(-17)[/tex]

[tex]y=-5x-17[/tex]

Therefore, the required equation is [tex]y=-5x-17[/tex].

I would personally say Florida. When looking at things such as race, NYC has many races, and New York has very different neighborhoods and lifestyles.

In Florida, most people are more laid back, and there are not that many differences in race and other aspects.

Answer:

464

Step-by-step explanation:

Find other angle:

<B = 180 - 165 - 11 = 4

Then plug in (opposite sides go together):

[tex]\frac{a}{sin 11}[/tex] = [tex]\frac{630}{sin 165}[/tex]

[tex]a = \frac{630 sin 11}{sin 165} = 464.454 = 464[/tex]

The length of side a in ΔABC is 460 inches.

A triangle is a three-sided closed-plane figure formed by joining three noncolinear points. Based on the side property triangles are of three types they are Equilateral triangle, Scalene triangle, and Isosceles triangle.

We know the sine rule of ΔABC which is a/sinA = b/sinB = c/sinC.

Given, In ΔABC, c = 630 inches, ∠C=165° and ∠A=11°.

∴ a/sinA = c/sinC.

a/sin11° = c/sin165°.

a/0.19 = 630/0.26.

a = (630×0.19)/0.26.

a = 460.

Step-by-step explanation:

9 1/5=46/5 ; 7 1/2=15/2

common denominator is 10

46/5-15/2=( 92-75)/10= 17/10= 1 7/10 feet= 1.7 feet

Answer:

We know that the measure of each side is:

5.2cm to 1 decimal place.

Then we can assume that the error is 0.05cm (half of the second decimal place).

With this, the interval of the length of each side will be:

(5.2cm - 0.05cm) = 5.15cm  (as the minimum)

(5.2cm + 0.05cm) = 5.25cm (as the maximum)

Then the interval is (5.15cm, 5.25cm)

2) We know that the perimeter of a square of sidelength L is:

P = 4*L

In this case, the minimum perimeter will be if we choose the smallest sidelength, this is:

P = 4*5.15cm = 20.6cm

And the maximum perimeter can be:

P = 4*5.25cm = 21cm

Then the interval is: (20.6cm, 21cm)

Here we can see that the error for the perimeter is 0.2cm, which is equal to 4 times the error of the length of a side (0.05cm) , as expected.

Answer:

3 tons, 1110 pounds

Step-by-step explanation:

A Ton weighs 2000 pounds, first convert the 4 tons.

You can solve this by multiplying 4 times 2000, and you will get 8000.

Now Add 8000 to 422, and your solution: 8422.

Now subtract 8422 by 1312, and you will get 7110.

Now convert this back to tons, start thinking, how many times can 2000 go into 7110.

That would be 3 my good sir.

The correct net is net a.

Surface area = sum of areas of the three rectangles and sum of the two triangles.

SA = (5 x 15) + (12 x 15) + (13 x 15) + (5 x 12) = 75 + 180 + 195 + 60 = 510 square inches.

Given:

The graph of a function [tex]y=h(x)[/tex].

To find:

The interval where [tex]h(x)>0[/tex].

Solution:

From the given graph graph it is clear that, the function before x=0 and after x=3.6 lies above the x-axis. So, [tex]h(x)>0[/tex] for [tex]x<0[/tex] and [tex]x>3.6[/tex].

The function between x=0 and x=3.6 lies below the x-axis. So, [tex]h(x)<0[/tex] for [tex]0<x<3.6[/tex].

Now,

For [tex]-1<x<0[/tex], the graph of h(x) is above the x-axis. So, [tex]h(x)>0[/tex].

For [tex]0<x<1[/tex], the graph of h(x) is below the x-axis. So, [tex]h(x)<0[/tex].

For [tex]1<x<2[/tex], the graph of h(x) is below the x-axis. So, [tex]h(x)<0[/tex].

Only for the interval [tex]-1<x<0[/tex], we get [tex]h(x)>0[/tex].

Therefore, the correct option is A.
