F(x)= -2x^2what is the vertex of this and/or how do you find the vertex??​

Mathematics
1 answer:
Doss [256]2 years ago
7 0

Answer:

(0,0)

Step-by-step explanation:

x value of vertex = -b/2a

ax^2+bx+c

-2x^2+0x+0 sinc you have no value of b & c in your quadratic function

-b = 0

2a = (2)(-2)

-b/2a = (0/-4) = 0

x value of the vertex = 0

plug 0 in for all values of x in the function to find y coordinate value

-2(0)^2 = 0

(x,y) = (0,0)

5. If the dimensions of a rectangle are doubled, which of the following best describes an effect on the rectangle?​
Bond [772]

Answer:

Since length and width are perpendicular, Doubling either one will double the area. So Doubling both will quadruple the area. 2x2 = 4.

This idea works if the dimensions doubled are those that are used to compute area. Like the base and height of a triangle.

More generally, in a polygon, if all the sides are doubled, the area is multiplied by 4. In a circle, Doubling the radius will quadruple the area.

In 3 dimensions, Doubling one dimension will double the VOLUME. Doubling two perpendicular dimensions will quadruple the volume and Doubling 3 perpendicular dimensions will multiply the volume by 2x2x2 or 8.

Lucy plans to spend between $50 and $60, inclusive, on packages of beads and packages of charms. If she buys 5 packages of beads
worty [1.4K]

She can buy maximum of 5 packages while staying within her budget.

Minimum spending limit = $50.

Maximum spending limit = $60.

Cost of one package of beads = $4.95.

Number of packages of beads bought = 5.

Cost of one package of charms = $6.55.

Let the number of packages of beads bought be x.

4.956 \times 5 + x \times 6.55 \geq 50

24.78+6.55x\geq 50

6.55x\geq 25.22

x\geq 3.85

4.956 \times 5 + x \times 6.55 \leq 60

24.78+6.55x\leq 60

6.55x\leq 35.22

x\leq 5.38

So, she can buy maximum of 5 packages while staying within her budget.
