Find the vertex of the parabola y = x2 + 5x.

Answers

Write the equation as a mathematical expression.
y = x^2+5x

Rewrite the equation in vertex form
y = (x+(5/2))^2 -(25/4)

Find a h and k using the vertex form y=a(x-h)^2 + k
a=1
h=(-5/2)
k= (-25/4)

answer: (-5/2 , -25/4)

A box is being packed with cubes that measure 1 cubic foot. What is the volume of the box in cubic feet

Answers

Answer:

81 cubic foot

Step-by-step explanation:

It is given that the box is packed with cubes whose side is 1 foot. So the volume of one cube is 1 cubic foot.

Now from the figure, we can see that :

Number of cubes fitting the box across its length = 9 cubes

Number of cubes fitting the box across its width = 3 cubes

Number of cubes fitting the box across its height = 3 cubes

And each of these cubes measures 1 x 1 x 1 cubic foot

So the volume of the box can be found out by:

Volume = length x width x height

= 9 x 3 x 3

= 81 cubic foot

Therefore volume of the box is 81 cubic foot.

tony completes one lap of a track every 20 seconds. diana completes one lap of the same track every 55 seconds. suppose tony and diana start at the starting line at the same time. how many seconds will it be before they cross the starting line at the same time again?

Hello there!

The slopes of perpendicular lines are opposite reciprocals.

So, if one line has a slope of 4, then the slope of the line perpendicular to it is the opposite of 4 flopped over (-1/4)
