Step-by-step explanation:
formula
(y-k)^2 = 4a(x-h) horizontal parabol
a = 7 - 2 =5
(y-k)^2 = 4*5*(x-h)
(y-k)^2 = 20(x-h)
k=3 , h=2

Solve negative 2 x plus 3 is greater than or equal to negative 3
Answer:equal
Step-by-step explanation:
Answer:
x is less than or equal to 3
Step-by-step explanation:
subtract three from both sides which will give you 2x is greater than or equal to -6. then divide by -2 on both sides to isolate x (dividing by a negative number flips the sign and a negative divided by a negative equals a positive) so then you get x is less than or equal to 3
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.

Lu is making a quilt that is 20 squares wide and has 15 rows. The border of the quilt is made by using each toy design equally as often. There are a total of 6 toy designs. Each square can hold one design. How many of each design does she use for the border?
Answer:
Out of 6 designs 4 designs will have 12 repetitions and 2 designs will have 11 repetitions.
Or
On the average each design will be repeated 11.67 times.
Step-by-step explanation:
HEre the width = 20 and length = 15
The perimeter = 2(l+b)
= 2( 20+ 15) = 70
The border of the quilt has 70 squares. Each square can have 1 design and there are 6 designs
Number of repetitions for each design = 70/6= 11. 67
6 designs can have 11 repetitions for 66 boxes= 6 *11= 66
4 squares will be left out. 70-66= 4
4 design can have additional repetition.
Meaning out of 6 designs 4 designs will have 12 repetitions and 2 designs will have 11 repetitions.
Or
On the average each design will be repeated 11.67 times.

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.

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
<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°.

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.
