-3 1/2 because if you do 2.8 times 1 and 1/4 you get 3.5 and 3.5 as a fraction is 3 1/2

What is the slope of the line graphed below??

Burka [1]

We can use the points (1, 2) and (3, -4) to solve.

Slope formula: y2-y1/x2-x1

= -4-2/3-1

= -6/2

= -3

Hope This helped! Good Luck!

Paige launched a ball using a catapult she built. The height of the ball (in meters above the ground) ttt seconds after launch i

agasfer [191]

Answer:

1) Factor form : $h(t)=-5t(t-8)$

2) 8 second after launch.

Step-by-step explanation:

The height of the ball (in meters above the ground) t seconds after launch is modeled by

$h(t)=-5t^2+40t$

To find the time when ball hit the ground, we need to find the factor form of the given function.

$h(t)=-5t(t-8)$

When ball hi the ground, then height of the ball from the ground is 0.

$h(t)=0$

$-5t(t-8)=0$

Using zero product property, we get

$-5t=0\Rightarrow t=0$

$t-8=0\Rightarrow t=8$

Ball hit the ground at t=0 and t=8. It means ball hit the ground in starting and 8 second after launch.

Solve p= 2/+ 2 w for w.

ryzh [129]

Answer:

B. W = (P - 2L) / 2

Step-by-step explanation:

(I'm gonna use capitals so it's easier to identify length and width variables)

P = 2L + 2W

Isolate w:

P - 2L = 2W

(P - 2L) / 2 = W

SIZIF [17.4K]

Answer:

6081 (original 1806)

Step-by-step explanation:

to get from 1/6 to 7 you must multiply by 42

then you multiply 42 by 43

42 * 43 = 1806

the answer is 1806 but the unlock code is backwards so its 6081

What is the circumference of a round pizza with an area of 36 square inches?

larisa [96]

Knowing that your area is: $A= \pi r^{2}=36 in^{2}$ you can find the radius as:
$r= \sqrt{ \frac{36}{ \pi } } =3.4 in$ ;
With this you can evaluate the circumference as:
$C=2 \pi r=2*3.14*3.4=21.3 in$
