Please help i’m confused

Answer:

This is the graph of a <u>parabolic</u> function.

  • Without seeing the dropdown menu, I assume that is what the question is asking. It's parabolic: the shape is like an upside-down u or an upside-down v.

Michael Jordan's hang time is <u>.9</u> seconds.

  • The parabola starts at 0 seconds, and ends at t = .9 seconds.

The maximum height is about <u>1</u> meter.

  • The vertex or very top of the parabola is at h = 1.

For t between t = .5 and t = 1, the height is <u>decreasing/falling/going down.</u>

  • I can't tell this one for sure unless I can see the dropdowns. But I can say that from .5 to 1, whatever it is, it's dropping or falling, because the height is getting less and less.

Figure ABCD is a trapezoid. Find
Rudiy27

Answer:

x = 3

Step-by-step explanation:

The midsegment is half the sum of the parallel bases, that is

\frac{1}{2} (3x + 3 + 4x + 2) = 13

\frac{1}{2} (7x + 5) = 13 ( multiply both sides by 2 )

7x + 5 = 26 ( subtract 5 from both sides )

7x = 21 ( divide both sides by 7 )

x = 3

Linear Functions <br> 7g+3g-10+3=43<br> Step by step solution? <br> Thankss!❤️
Ivahew [28]
7g + 3g - 10 + 3 = 43

(first combine likes terms)

10g - 7 = 43

(then add 7 to both sides)

10g - 7 = 43
        +7    +7

10g = 50

(then divide by 10 to get what g is equal to)

10g = 50
/10     /10

g = 5
