Answer:

The vertex is -5/2 and -9/2

Step-by-step explanation:

I looked it up on math

way

A parabola is a mirror-symmetrical planar curve that is nearly U-shaped. The vertex of the parabola y = 2x² + 10x + 8 is (-2.5, -4.5).

A quadratic equation is an equation whose leading coefficient is of second degree also the equation has only one unknown while it has 3 unknown numbers. It is written in the form of ax²+bx+c.

Then its roots are given as:

[tex]x = \dfrac{-b \pm \sqrt{b^2 - 4ac}}{2a}[/tex]

A parabola is a mirror-symmetrical planar curve that is nearly U-shaped.

y = a(x-h)² + k

where,

(h, k) are the coordinates of the vertex of the parabola in the form (x, y);

a defines how narrower the parabola is, and the "-" or "+" that the parabola will open up or down.

The general form of a parabola is written in the form ax²+bx+c, which is a quadratic equation. While the vertex form of the parabola is written as y=a(x-h)² + k.

Given that the equation of the parabola is y = 2x² + 10x + 8. Now if we compare the general equation of the parabola with ax²+bx+c, the value of a, b, and c will be 2, 10, and 8, respectively.

Further, the vertex of the parabola can be written as,

h =−b/2a

h = -10 / 2(2)

h = -10/4

h = -2.5

k = -(b² - 4ac) / 4a

k = -[10² - 4(2)(8)] / 4(2)

k = (100 - 64) / 8

k = -36/8

k = -4.5

Hence, the vertex of the parabola y = 2x² + 10x + 8 is (-2.5, -4.5).

Answer:

Step-by-step explanation:

The x and y points are multiplied by 1.5

See the graph

Notice that if you start with (4,6) and dilate by a scale of 1.5 then the final point is (6,9)

The slope of these two points (if they were on a line should be 1.5

x2 = 6

x1 = 4

y2 = 9

y1 = 6

m = (9 - 6)/(6 - 4)

m = 3 / 2

m = 1.5 which is what it should be.

The x-coordinate of every point of the figure is multiplied by 1.5.

The scale factor is 1.5, and the center of dilation is the origin (0, 0).

When the figure is dilated by a scale factor of 1.5 with the origin as the center, it means that each point's x-coordinate and y-coordinate are separately multiplied by 1.5.

The y-coordinate of every point of the figure is multiplied by 1.5 is not correct the reason is that in this specific dilation scenario, only the x-coordinate is multiplied by 1.5, while the y-coordinate remains the same. The origin as the center of dilation means that the points move away from or towards the origin, maintaining the same vertical distance.

Therefore, the correct description is "The x-coordinate of every point of the figure is multiplied by 1.5."

Answer:

104

This is because angle at the center is twice the angle at the circumference

Step-by-step explanation:

104 is the size of obtuse angle DOF because the angle at the center is twice the angle at the circumference.

An obtuse angle is any angle greater than 90 °: Straight angle is a measurement angle equal to 180 °: Zero angles is a measurement angle equal to 0 °: Complementary angle is the angle at which the sum of the measurements is 90 °: Complementary angles are the following angles: The total dimensions are 180 °.

Now we know that angles below 180 degrees and above 90 degrees are obtuse. Examples of bluntness include 110 °, 135 °, 150 °, 179 °, 91 °. Therefore, all angles in the range of 90 ° to 180 ° are obtuse.

Answer:

V=37.68

Step-by-step explanation:

The formula for the volume of a cone is V=1/3πr^2h.  First, plug the values in to the varibles to get V=1/3π3^2(4), since 3 is the radius and 4 is the height.  Now simplify the equation.  

V=1/3π3^2(4)

V=1/3π9(4)

V=1/3π36

Multiply 36 by pi, which the equation wants you to use as 3.14.  

V=1/3(113.04)

Now simplify to get V=37.68.
