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
Answers
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.

Answer:
x = y = 10
Step-by-step explanation:
Using the cosine ratio in the right triangle and the exact value
cos45° = [tex]\frac{1}{\sqrt{2} }[/tex] , then
cos45° = [tex]\frac{adjacent}{hypotenuse}[/tex] = [tex]\frac{x}{10\sqrt{2} }[/tex] = [tex]\frac{1}{\sqrt{2} }[/tex] ( cross- multiply )
x × [tex]\sqrt{2}[/tex] = 10[tex]\sqrt{2}[/tex] ( divide both sides by [tex]\sqrt{2}[/tex] )
x = 10
Since the base angles are 45° then the triangle is isosceles and the 2 legs are congruent, then
x = y = 10
Anthony wants to find the value of k for which given points W(0,-2), I(2,0) and L(5,k) are collinear
A. K=-3
B. K=1/3
C. K=1/2
D. K=2
E. K=3
F. K=-1/3
Answers
Given:
The three points are W(0,-2), I(2,0) and L(5,k).
To find:
The value of k for which the given points are collinear.
Solution:
We know that, three points are collinear if the area of the triangle formed by these three points is 0.
[tex]\dfrac{1}{2}|x_1(y_2-y_3)+x_2(y_3-y_1)+x_3(y_1-y_2)|=0[/tex]
[tex]x_1(y_2-y_3)+x_2(y_3-y_1)+x_3(y_1-y_2)=0[/tex]
The three points are W(0,-2), I(2,0) and L(5,k). So,
[tex]0(0-k)+2(k-(-2))+5(-2-0)=0[/tex]
[tex]0+2(k+2)+5(-2)=0[/tex]
[tex]2k+4-10=0[/tex]
[tex]2k-6=0[/tex]
Adding 6 on both sides, we get
[tex]2k=6[/tex]
[tex]k=\dfrac{6}{2}[/tex]
[tex]k=3[/tex]
Therefore, the correct option is E.

The first step is to find the volume of the two hemispheres.
Step-by-step explanation:
[tex]\boxed{volume \: of \: sphere = \frac{4}{3} \pi {r}^{3} }[/tex]
Since the 2 hemispheres have the same radius, we can simply find the volume of a sphere.
Volume of sphere
[tex] = \frac{4}{3}( \pi)( {12}^{3} )[/tex]
[tex] = 2304\pi \: in^{3} [/tex]
Volume of solid
= volume of cylinder -volume of 2 hemispheres
Let's find the volume of the cylinder.
[tex]\boxed{voume \: of \: cylinder = \pi {r}^{2}h }[/tex]
Volume of cylinder
[tex] = \pi( {12}^{2} )(24)[/tex]
[tex] = 3456\pi \: in^{3} [/tex]
Thus, volume of solid
[tex] = 3456\pi - 2304\pi[/tex]
[tex] = 1152\pi[/tex]
[tex] = 1152(3.14)[/tex]
[tex] = 3617.28 \: in^{3} [/tex]
Answer:
Solution :-Volume of solid = Volume of Sphere - Volume of cylinder
Volume = 4/3πr³ - πr²h
Volume = 4/3 • π • 12³ - π • 12² • 24
Volume = 4/3 • π • 1728 - π • 144 • 24
Volume = 4 • π • 576 - π • 3456
Volume = π(3456 - 2304)
Volume = π(1152)
Volume = 3619.11 in³

3x + 90 = 144
Subtract 90 from both sides
3x = 144 - 90
3x = 54
Divide both sides by 3
x = 54/3
x = 18

To find a y term, find the absolute value of the x term (|x|).
Absolute value - the distance between 0 and a number. The absolute value of a number will always be equal to the positive form of the number (if it isn't already positive).
Some examples: The absolute value of 18 is 18. The absolute value of -10 is 10.
Find the absolute value of each x term to find y:
x ⇒ y
-2 ⇒ 2
-1 ⇒ 1
0 ⇒ 0 (the absolute value of 0 is always 0)
1 ⇒ 1
2 ⇒ 2

The temperature in an oven changes from 350 degrees to 362 degree. What is the percent increase in temperature, to the nearest tenth of a percent?
Answers
Answer:
3.4%
Step-by-step explanation:
Find the percent increase by dividing the difference in the temperatures by the original temperature, then multiplying it by 100:
((362 - 350) / 350) x 100
(12 / 350) x 100
= approximately 3.4
So, the percent increase in temperature was approximately 3.4%
