Answer:

Step-by-step explanation:

Range goes from the lowest point on a graph to the highest point, not including anything in between those 2 extremes. We will evaluate the quadratic for the values given. First f(2):

f(2)=(2)^2-5 so

f(2) = -1

Now, f(4):

f(4)=(4)^2-5 so

f(4) = 11

Now, f(7):

f(7)=(7)^2-5 so

f(7) = 44

The lowest y value is -1 and the highest is 44, so the range is from -1 to 44 (I can't tell which of your choices reflects that because it's too small!)

Answer: It's correct because it is the only one with an angle more than 180°

Step-by-step explanation:

D is a right angle, A is an acute angle, as well as B. So not only is C the only one with an obtuse angle and it also has the biggest angle out of the other two angles on the triangle, you can use process of elimination to figure it out as well. Hope this helps, have a good day! :-)

Answer:

64 degrees

Step-by-step explanation:

Since the triangles are similar they have the same angle measures

\frac{PR}{PQ} =\frac{SU}{ST}          \frac{21}{14}= \frac{6}{4}

∠P = ∠S ∠R =∠U ∠Q=∠T

We know 2 of the angle measures: ∠S and ∠R, and since they are similar we know ∠P and ∠U

In triangles the sum of all angle measures is always 180 degrees, so we can solve for ∠Q with this formula

A+B+C=180

46+70+C+180

116+C=180

subtract 116 from both sides

C=64

Therefore ∠Q is equal to 64 degrees
