How many turning points are in the graph of the polynomial function?
a.) 4 turning points
b.) 5 turning points
c.) 6 turning points
d.) 7 turning points
5 turning points are in the graph of the polynomial function.
What are Turning point in graph?Turning points occur when a graph shifts from rising to dropping (rising to falling) or from decreasing to increasing (falling to rising). A polynomial of degree n can turn at most once, or n1.
The point on a parabola where the graph shifts from increasing to decreasing, or from decreasing to increasing, is known as the turning point of a parabola and is also known as the vertex. We refer to a graph as growing when it is rising from left to right.
Turning points are places on a graph where the direction of the line switches from upward to downward.
And from below to above.
We can see that graph is changing its direction at 5 different points and the points are
(-5,6) ,(-3,-3) ,(0.5,0.5) ,(3,2.5) ,(5,5)
Thus, there are 5 turning points.

The standard equation of a line is y = mx,+b
m is the slope
b is he y-inttercept
Get the slope
Slope m = y2-y1/x2-x1
Substitute the coordinate
M = 1-4/2-(-4)
M = -3/6
M = -1/2
Substitute m= -1/2 and (2,1) into y = mx+b
1 = -1/2(2)+b
1 = -1+b
b = 1+1
b=2
Get the equation
Recall y =mx+b
y = -1/2 x + 2

The value of sin(θ) is -5√41/41 because sin is negative in the fourth quadrant option (A) -5√41/41 is correct.
What is trigonometry?Trigonometry is a branch of mathematics that deals with the relationship between sides and angles of a right-angle triangle.
We have:
cos(θ) = 4√41/41
As we know cos is the ratio of the side adjacent to the angle to the hypotenuse.
cos(θ) = adjacent/hypotenuse
From the Pythagoras theorem:
hypotenuse² = opposite² + adjacent²
41² = opposite² + (4√41)²
After calculating:
opposite = √1025
opposite = -5√41 (because sin is negative in the fourth quadrant)
sin is the ratio of the opposite to hypotenuse:
sin(θ) = -5√41/41
Thus, the value of sin(θ) is -5√41/41 because sin is negative in the fourth quadrant option (A) -5√41/41 is correct.

Bella do you know the distance formula? that's the "tool" you need for these questions. :) Answers are bolded below :)
Step-by-step explanation:
dist = sqrt[ x2-x1)^2 +(y2-y1)^2]
Robins house is at Point P1 = (-9,10) in the form (x1,y1)
Sarah's house is at Point P2=(3,5) in the form (x2,y2)
dist from Robin's to Sarah's is
dist_RS = sqrt[ (3-(-9))^2 +(5-10)^2]
dist_RS = sqrt[ (3+9)^2 + (-5)^2]
dist_RS = sqrt[ 12^2 + 25 ]
dist_RS = sqrt [ 144+25]
dist_RS = sqrt [ 169]
dist_RS = 13
distance from Robin's to Jada's
where Jada's house is at Point P3 =(-3,2) in the form (x3,y3) (we can think of this as P2 in the form (x2,y2) in our formula)
dist_R J= sqrt [ (-3-(-9))^2 + (2-10)^2 ]
dist_R J= sqrt [ (-3+9)^2 + (-8)^2 ]
dist_R J= sqrt [ (6)^2 + 64 ]
dist_R J= sqrt [ 36 + 64]
dist_R J= sqrt [ 100 ]
dist_R J= 10
distance to Madison's house
where Madison's house is at Point P4 = (-1,-5) in the form (x2,y2)
dist_RM = sqrt [ (-1-(-9))^2 + (-5-10)^2 ]
dist_RM = sqrt [ (-1+9)^2 + (-15)^2 ]
dist_RM = sqrt [8^2 + 225 ]
dist_RM = sqrt [ 64 + 225 ]
dist_RM = sqrt [289 ]
dist_RM = 17
Jada's house is 10 , Madison's is 17 so it's 7 miles farther to Madison's than to Jada's

can you say a triangle with equal angles of 60 is equilateral
Answer:
Not really
Step-by-step explanation:
NOT NECESSARILY would a triangle be equilateral if one of its angles is 60 degrees. To be an equilateral triangle (a triangle in which all 3 sides have the same length), all 3 angles of the triangle would have to be 60°-angles; however, the triangle could be a 30°-60°-90° right triangle in which the side opposite the 30 degree angle is one-half as long as the hypotenuse, and the length of the side opposite the 60 degree angle is √3/2 as long as the hypotenuse. Another of possibly many examples would be a triangle with angles of 60°, 40°, and 80° which has opposite sides of lengths 2, 1.4845 (rounded to 4 decimal places), and 2.2743 (rounded to 4 decimal places), respectively, the last two of which were determined by using the Law of Sines: "In any triangle ABC, having sides of length a, b, and c, the following relationships are true: a/sin A = b/sin B = c/sin C."¹
Step-by-step explanation:
A triangle with three equal interior angles is called an equiangular triangle. In an equiangular triangle has three. equal sides, and it is the same as an equilateral triangle.

Therefore, each angle measures 60°.
<1 and <2 are complementary angles given m<1 = 12 find m<2 =
Answer:
m∠2=78°
Step-by-step explanation:
∡2=90°-∡1=90°-12°=78°, therefore ∡2=78°
The measure of ∠2 is 78°.
We have two angles ∠1 and ∠2 which are complementary angles such that ∠1 = 12°.
We have to find the measure of ∠2.
What are Complementary angles ?When the sum of two angles is equal to 90 degrees, they are called complementary angles.
∠X + ∠Y = 90
According to the question, we have -
The measure of angle ∠1 = 12°.
Assume that the magnitude of ∠2 is x.
Then -
∠ 1 + x = 90°
x = 90° - ∠1
x = 90° - 12°
x = 78°
Hence, the measure of ∠2 is 78°.
