Mathematics

hoa [83]3 years ago

Multiplying and dividing integers with the same sign and different signs.

When multiplying and dividing with the same sign, the answer will always be positive.

6/3 = 2

-6*-3=18 (Two negatives make a positive)

-4/-2=2 (This is because there are two -2s in -4, so the answer will always be positive- also two negatives make a positive.)

When multiplying and dividing by different signs, the answer will always be negative.

3*-6= -18

4/-2 = -2

Because the answer will always by negative, you can multiply or divide normally and then just add the negative sign (-) in front of the answer.

1.<br> Find the slope of the line.<br> Ay<br> a) -574<br> b) 5/4<br> c) -4/5<br> d) 4/5
maria [59]

Answer:

a) -5/4

Step-by-step explanation:

Slope is fundamentally rise/run; The points on the line are relative to each other by decreasing/increasing the y-value of +/-5 and decreasing/increasing the x-value by +/-4

The function is decreasing so the slope has to be negative.

The only possible answer choice is -5/4 or a.

A ball is thrown into the air with an upward velocity of 36 ft/s. Its height h in feet after t seconds is given by the function
FinnZ [79.3K]

Answer:

The ball reaches a height of 29.25 ft after 1.125 seconds

Step-by-step explanation:

The maximum height of a parabola can always be found by looking for the vertex. You can find the x value (or in this case the t value) of a vertex by using -b/2a in which a is the coefficient of x^2 and b is the coefficient of x.

-b/2a

-(36)/2(-16)

-36/-32

1.125 seconds

Now to find the height, we input that value in for t

h = -16t^2 + 36t + 9

h = -16(1.125)^2 + 26(1.125) + 9

29.25 feet
