PLEASE HELP ASAP!!!!!

Mathematics
1 answer:
maw [93]3 years ago

Answer:

D

Step-by-step explanation

Since we are reflecting across the x axis, all of the y coordinates will remain the same. You find the distance away from the x = 4, double it, and add that value to x. So,

X' is now (8,3)

Y' is now  (6,0)

Z' is now (4,2) because its x was 0, and anything * 0 = 0 so it does not move.

Answer:

76 degrees.

Step-by-step explanation:

Let as consider O is the center of the circle . So from the figure it is clear that

\angle AOB=44^{\circ}

\angle COD=118^{\circ}

By central angle theorem, central angle subtended by an arc is twice of inscribed angle of the same arc.

We know that, \angle BAD=97^{\circ} and angle BOD is the central angle subtended by arc BD.

\angle BOD=2\times \angle BAD

\angle BOD=2\times 97^{\circ}

\angle BOD=194^{\circ}

Now,

\angle BOD=\angle BOC+\angle COD

194^{\circ}=\angle BOC+118^{\circ}

194^{\circ}-118^{\circ}=\angle BOC

76^{\circ}=\angle BOC

m(arc(BC))=76^{\circ}

Therefore, the measure of arc BC is 76 degrees.

Consider the graph with four lines below. On a coordinate plane, line a has a positive slope and goes through points (negative 1
yan [13]

Answer:

The correct option is;

line a and line b

Step-by-step explanation:

Lina a passes through (-1, 0) and (1, 2)

Line b passes through (2, 2) and (-1, -1)

Line c passes through (0, 3) and (1, 0)

Line d passes through y = 1

An equation that has no solution

By examination, from the plot of the coordinates using an online tool, the system that would have no solution is the system of line a and line b because they are parallel lines and cannot meet or have a point where there is a common solution, therefore, there are no solutions when the equations of the two lines are combined in one equation

Slope of line a = -2/-2 = 1

Slope of line b = 3/3 = 1

The slopes of lines a and b are equal, therefore, line a and line b are parallel.

It takes 22 minutes for 10 people to paint 10 walls. How many minutes does it take 14 people to paint 14 walls?
4vir4ik [10]
220pm=10w  (people*minutes)

w=22pm

14w=308pm

308pm/14p=22m

So it would take 22 minutes for 14 people to paint 14 walls.

Mr. Morales owns a warehouse that is 56,000 cubic feet. He wants to build an addition that will increase the size of the warehou
Gennadij [26K]

Answer:

62,160 cubic feet

Step-by-step explanation:

To solve this problem, we can use a percentage formula as shown below:

P(1+r)

<em>P = initial value</em>

<em>r = rate</em>

Now lets plug in the values given in the question:

56,000(1+.11) = 62,160

This means that the volume of the warehouse after the addition will be 62,160 cubic feet.
