⁕ Remember that slope formula is:

[tex]m = \frac{y_2 - y_1 }{x_2 - x_1}[/tex]

⁕ Let's plug in and solve.

Which of the following are magnitudes for rotational symmetry of the ellipse below about its center?
Choose all answer that apply:
All magnitudes less than 360°
180°
270°

Answers

Answer:

180 bestie

Step-by-step explanation:

The magnitude of rotational symmetry of the given ellipse is angle 180°.

What is the equation of ellipse if its major and minor axis and center are given?

Suppose that the major axis is of the length 2a units, and that minor axis is of 2b units, and let the ellipse is centered on (h,k) with major ellipse parallel to x-axis,

then the equation of that ellipse would be:

[tex]\dfrac{(x-h)^2}{a^2} + \dfrac{(y-k)^2}{b^2} =1[/tex]

Coordinates of its foci would be:  [tex](h \pm c, k)[/tex] where   c^2 = a^2 - b^2

Let the magnitude of rotational symmetry of the given ellipse is angle θ.

Measure of angle θ is a straight line.

Measure of angle θ = 180°

Therefore, with a rotation of 180° ellipse will overlap itself.

Volume of the following triangular prism is 960 cm3…
a) Determine the length of the base of the triangle.
b) Determine the area of the triangle.
help plz

Answers

Answer:

Step-by-step explanation:

a). By applying Pythagoras theorem in right triangle ABC,

AC² = AB² + BC²

20² = 16² + BC²

BC = [tex]\sqrt{400-256}[/tex]

     = 12

Therefore, another leg of the triangular base = 12 cm

Area of the triangular base ABC = [tex]\frac{1}{2}(\text{Base})(\text{Height})[/tex]

                                                      = [tex]\frac{1}{2}(16)(12)[/tex]

                                                      = 96 cm²

Volume of a triangular prism = Area of the triangular base × height

                                       960 = 96 × b

                                          b = 10 cm

b). Area of the triangle ABC = 96 cm²

Given f(x) = x^3 + kx + 2, and x + 1 is a factor of f(x), then what is the value of
k?

Answers

Answer:

k = 1

Step-by-step explanation:

Given that,

[tex]f(x) = x^3 +kx + 2[/tex]

If (x+1) is a factor of (x), we need to find the value of k.

Using remainder theorem to find it.

Put (x+1) = 0

x = -1

Put x = -1 in equation below.

[tex]x^3 + kx + 2=0\\\\(-1)^3+k(-1)+2=0\\\\-1-k+2=0\\\\1-k=0\\\\k=1[/tex]

So, the value of k is 1.

so 8x10 + 15x5 = 80 + 75 = 155

method B

one traingle with lenghts 5 and 7

the other 15 and 8

so 15x8 + 5x7 = 120 + 35 = 155

It will be A because 15+15+10+8+7+5=60 I think

Answer:

x-intercept (6,0)

y-intercept (0,-4.5)

Step-by-step explanation:

the x-intercept will be when y=0

and the y-intercept will be when x=0

so

[tex]y=0\\\\-6x+8(0)=-36\\\\-6x=-36\\\\x=6[/tex]

so the x intercept will be at (6,0)

[tex]x=0\\\\-6(0)+8y=-36\\\\8y=-36\\\\y=-\frac{9}{2}\\\\y=-4.5[/tex]

so the y intercept will be at (0,-4.5)

An air traffic controller is tracking two planes. To start, Plane A is at an altitude of 4385 feet and Plane B is at an altitude of 5000 feet. Plane A is gaining altitude at 55.5 feet per second and Plane B is gaining altitude at 45.25 feet per second.

How many seconds will pass before the planes are at the same altitude?
seconds
What will their altitude be when they're at the same altitude?
feet

Answers

Answer:

60 seconds, 7715 feet

Step-by-step explanation:

Plane A and B start out 615 feet apart, and we find this by subtracting the height of plane A from plane B, getting 5000-4385=615. Now we have to find how many more feet of altitude plane A is gaining per second over plane B.

To find this we subtract 45.25 from 55.5 and get 10.25 feet per second. Now to find out how many seconds until they'll be at the same altitude we simply divide 615 by 10.25, getting 60 seconds.

For the second part, to find the altitude at this point, we simply multiply the altitude gain of one of the planes per second by the time of 60 seconds to get how much altitude they gained over that time, and add it to the starting altitude. Doing this with plane B we get 45.25*60=2715, and we add that to 5000 to get the final answer of 7715.
