The answer is A) 5 inches.
If TR is the migsegment, then R is the midpoint of BC. If R is the midpoint of BC, then RC is equal to BR.
Hope this helps! :)
Answer:
If you mean the percentage error then look at this
Step-by-step explanation:
% error = <u>Estimated </u><u>-</u><u> </u><u>Actual </u> x <u>100 </u>
Estimated. 1
% error = <u>7000 - 5600</u> x <u>100 </u>
7000. 1
% error = <u>1400 x </u><u>100</u>
7000
% error = 140000/7000
% error = 20%

Answer:
Answer:age of new student is 13.4 years
Step-by-step explanation:
SUM of ages all 40 students =average age times 40
=15*40=600
after leaving 18 years old student
SUM of ages of 39 students will be 600-18=582
after adding new student with age x
SUM of ages of 40 students will become 582+x
and the average would be (582+x)/40
which is given as 14.885
so we get equation
(582+x)/40=14.885
582+x=14.885*40=595.4
x=595.4-582
x= 13.4
age of new student is 13.4 years

Okay so I attatched pictures of my work. I would just graph it by plugging in x-values on either side of the vertex into the equation. For example, the vertex is at (-2,3). So try plugging x=-5 and x=1 into the equation (y=a(x-h)^2 +k).
y=(x+2)^2 +3
y=((1)+2)^2 +3=(3)^2+3= 9+3=
12
Now you can plot the vertex (-2,3), the point (1,12), and (-5,12). From there just connect the dots and you should get a graph that looks similar to the last picture I attached. Hope this all made sense sorry it was so wordy I just wasn't sure how much you knew or didn't know. So, I thought it would be better to explain it all rather than not enough.
