Answer:
The scale factor is equal to 1/2
The dimensions of each channel when splits the screen is 46 in x 38 in
Step-by-step explanation:
we know that
The dimensions of the new television is 92 in x 76 in
Remember that
If two figures are similar, then the ratio of its areas is equal to the scale factor squared
Let
A1 -----> the area of the new television
A2 ----> the area of each channel when splits the screen
z-----> the scale factor

we have that
The area of the new television is 4 times the area of each channel



-----> the scale factor
so
When splits the screen, the dimension of each channel is equal to
92/2 in x 76/2 in
so
46 in x 38 in
Remember, if two figures are similar then the scale factor is equal to the ratio of their corresponding sides
<em>Verify the value of the scale factor</em>
92/46=1/2
or
76/38=1/2
Answer:
517
Step-by-step explanation:
The radius of a circle is just half of the diameter (1/2d = r)
1034/2 = 517
Answer:
y = -2x + 6
Step-by-step explanation:
y = mx + c
m = (2-4)/(2-1) = -2/1
m = -2
y = -2x + c
When x = 1, y = 4
4 = -2(1) + c
c = 4 + 2 = 6
y = -2x + 6
Answer:
2 distinct real number zeros
Step-by-step explanation:
The discriminant b^2 - 4ac
= (-17)^2 - 4*4*3
= 241
So it has 2 distinct roots.
Hello from MrBillDoesMath!
Answer: Only the top left relation is a function.
Discussion:
In the other 3 relations, a vertical line drawn through their graphs intersects the graph in more than 1 point (meaning they aren't functions)
