First question:

When you bisect an angle, you create two new equal angles, both measuring half of the original angle. So, if the original angle was 52°, the two angles will be 52/2=26 degrees each.

Note: the picture is not very clear, and I'm not sure the original angle is 52°. It it's not, just divide by 2 whatever measure the angle is.

Second question:

Focus on triangles RQP and RSP:

  • They are both right, because Q and S are right angles
  • We are given QP=SP
  • They share the side RP

So, they are congruent. This implies that angle SRP is 50° as well, and then

QRS = QRP+SRP = 50°+50°=100°

What is the slope of a line that runs parallel to y= x + 14
MAXImum [283]

Answer:

m=1

Step-by-step explanation:

y= x + 14

This equation is in slope intercept form

y = mx+b where m is the slope and b is the y intercept

The slope for the line is 1

Parallel lines have the same slope

m=1

What is the vertex of the graph of y = 1/3 (x-9)2 + 5 Question 1 options: (9,5) (3,3) (3,5) (-9,5)
svlad2 [7]
ANSWER

The vertex of the graph of
y =  \frac{1}{3}  {(x - 9)}^{2}  + 5
is

(9,5)



EXPLANATION

The vertex form of a parabola is given by

y = a {(x - h)}^{2}  + k

where
V(h,k)
is the vertex of the parabola.


The function given to us is

y =  \frac{1}{3}  {(x - 9)}^{2}  + 5
This is already in the vertex form.


When we compare this to the general vertex form, we have,

a =  \frac{1}{3}

h = 9
and

k = 5


Therefore the vertex of the parabola is

V(9,5)

Hence the correct answer is option A.

The expression 2.85+2.70M gives the taxi fare in dollars for a trip of M miles. On Thursday you got a find Miss Hearst took a ta
horrorfan [7]

<u><em>Answer:</em></u>

Total fair of the two trips was $32.7

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

<u>We are given that the expression that taxi fair is:</u>

2.85 + 2.7M where M represents the number of miles

<u>1- For Thursday:</u>

Number of miles covered = M = 6 miles

<u>Substitute with M=6 in the given equation to get the fair on Thursday as follows:</u>

Fair on Thursday = 2.85 + 2.7(6) = $19.05

<u>2- For Friday:</u>

Number of miles covered = M = 4 miles

<u>Substitute with M=4 in the given equation to get the fair on Friday as follows:</u>

Fair on Friday = 2.85 + 2.7(4) = $13.65

<u>3- The total fair:</u>

Total fair = fair on Thursday + fair on Friday

Total fair = 19.05 + 13.65 = $32.7

Hope this helps :)
