A food packet is dropped from a helicopter and is modeled by the function f(x) = -16x2 + 14400. The graph below shows the height

f(x), in feet, of the food packet at different times x, in seconds:
Use the graph to determine the reasonable domain of f(x) based on the context.


0 ≤ x ≤ 30

0 ≤ x ≤ 14400

-30 ≤ x ≤ 30

Answer:

Rational

Integer

Whole

Real

Step-by-step explanation:

<u>Rational</u><u>:</u><u> </u>

The square root of 4 is 2, which is an integer (number without decimals). A number is only irrational if it has endless decimals after it.

<u>Integer</u><u>:</u>

A number without decimals

<u>Whole:</u>

A number without fractions; an integer.

<u>Real: </u>

Real numbers include whole numbers, rational numbers and irrational numbers- pretty much any number you can think of. The only numbers that ARENT considered real are imaginary numbers like √-1 and infinity.

The equation of the line that contains diagonal HM is y = 2/3 x + 7.
nirvana33 [79]

Answer:

The slope of the line that contains diagonal OE will be = -3/2

Step-by-step explanation:

We know the slope-intercept form of the line equation

y = mx+b

Where m is the slope and b is the y-intercept

Given the equation of the line that contains diagonal HM is y = 2/3 x + 7

y = 2/3 x + 7

comparing the equation with the slope-intercept form of the line equation

y = mx+b

Thus, slope = m = 2/3

  • We know that the diagonals are perpendicular bisectors of each other.

As we have to determine the slope of the line that contains diagonal OE.

As the slope of the line that contains diagonal HM = 2/3

We also know that a line perpendicular to another line contains a slope that is the negative reciprocal of the slope of the other line.

Therefore, the slope of the line that contains diagonal

OE will be = -1/m = -1/(2/3) = -3/2

Hence, the slope of the line that contains diagonal OE will be = -3/2

Factor Completely.3g^2-78g+75
Umnica [9.8K]

✧・゚: *✧・゚:*    *:・゚✧*:・゚✧

                  Hello!

✧・゚: *✧・゚:*    *:・゚✧*:・゚✧

❖ 3g^2 - 78g + 75 factored completely is 3(g-1) * (g-25)

First, write the expression as a difference:

3(g^{2} -26g +25)

Then factor the expression:

3(g^{2} - g - 25g + 25)

Factor the expression again:

3 (g*(g-1)-25(g-1))

Your final answer should be:

3(g-1)*(g-25)
