To find the area of a trapezoid, it’s 1/2(base 1 + base 2) x height.
so in this case, base 1 is 16 (add 12+2+2) (the top one) and base 2 is 12 (the bottom one) and the height is 9.
you input all the values in the formula and you get 126in.
hope this helped:)

Tell whether you can reach each type of conclusion below using coordinate
Korvikt [17]

The answer to all of them is yes.

6) The lengths of AB and CD using the distance formula. (because congruent segments have equal length)

7) The slopes of AB and CD are equal using the slope formula. (because parallel segments have equal slopesL

8) The slopes of AB and CD are negative reciprocals using the slope formula. (because perpendicular lines have slopes that are negative reciprocals)

9) The two segments that CD is split into by AB have equal length using the distance formula. (because a segment bisector splits a segment into two congruent segments, and congruent segments have equal length)

10) Angles CAB and DAB have the same measure using the angle between two lines formula. (Because an angle bisector splits an angle into two congruent angles, and congruent angles have equal measure)

11) Angles A and B have the same measure using the angle between two lines formula. (Because an angle bisector splits an angle into two congruent angles, and congruent angles have equal measure)

12) The lines that form angle A have slopes that are negative reciprocals using the slope formula. (because perpendicular lines have slopes that are negative reciprocals, and perpendicular lines form right angles)

13) The lengths of AB and AC combined equal the length of AC using the distance formula.

14) Two sides of triangle ABC have equal length using the distance formula.

15) All four sides of ABCD have the same length using the distance formula.

16) Letting AB and CD meet at E, the distance formula says AE=BE and CE=DE.

Graph the equation. y=2x^2-8x+3y=2x 2 −8x+3
Gwar [14]

9514 1404 393

Answer:

  see attached

Step-by-step explanation:

The equation can be rewritten to vertex form, so you can tell the vertex is at (2, -5). The leading coefficient of 2 means the points will be twice as far apart vertically than they would be if the leading coefficient were 1. A couple of points are shown in the attached.

  y = 2(x^2 -4x) +3

  y = 2(x^2 -4x +4) +3 -8 . . . . . . complete the square

  y = 2(x -2)^2 -5 . . . . . . . . . . . . finish putting in vertex form

A certain forest covers an area of 2600 km2. Suppose that each year this area decreases by 7.75%. What will the area be like aft
kakasveta [241]

Answer:

After 15 years, the area will be of 775.3 km²

Step-by-step explanation:

The equation for the area of the forest after t years has the following format.

A(t) = A(0)(1-r)^{t}

In which A(0) is the initial area and r is the yearly decrease rate.

A certain forest covers an area of 2600 km2.

This means that A(0) = 2600

Suppose that each year this area decreases by 7.75%.

This means that r = 0.0775

So

A(t) = 2600(1-0.0775)^{t}

A(t) = 2600(0.9225)^{t}

What will the area be like after 15 years?

This is A(15)

A(t) = 2600(0.9225)^{t}

A(15) = 2600(0.9225)^{15} = 775.3

After 15 years, the area will be of 775.3 km²

I don’t know how to do that
Alisiya [41]

Answer:

16

Step-by-step explanation:

Divide 64 by 8 to get 8. this is 1/8 of the books.

3/8 were non fiction, or 24

1/4 (2/8) were picture books, or 16

5/8 were non fiction or picture books, so ’the rest‘ of the chapter books is 3/8.

3/8 were chapter books, or 24.

add the amount of picture books and chapter books since they are the fictional texts.

16+24=40

subtract the amount of non fictional books from the amount of fictional books to get the sum.

40-24=16

A cannon launches a cannonball from a height of 3 feet with an upward velocity of 40 feet per second. The function h=-16t^2+40t+
gavmur [86]
A)  We want to know when h=10 so

10=-16t^2+40t+3

16t^2-40t+7=0

Using the quadratic formula:

t=(40±√1152)/32 

t≈0.189 and 2.311 seconds

So it is at 10 ft twice, about 2/10 of a second when it is rising and at 2 3/10 of a second when it is falling...

b.

The maximum height of the ball is when velocity is equal to zero, or dh/dt=0

dh/dt=-32t+40, dh/dt=0 when 32t=40, t=40/32=5/4=1.25 seconds

h(1.25)=28ft

So the maximum height of the ball occurs after 1.25 seconds and reaches a height of 28 feet.
