Should be 2w + 12. Could be wrong because it’s been a while lol

2w+12
you multiply w by 2 and then add 12, the equation can’t be answered without the value of w

Dylan has a square piece of metal that measures 10 inches on each side. he cuts the metal along the diagonal, forming two right

Artemon [7]

You need to use the Pythagorean theory. a² + b² = c². So you would end up with 10²+10²=c². So, 10²=100, therefore you would end up with 200=c². In order to find the length of the hypotenuse, you need to find C. To do this, you need to undo the square and find the square root of 200 and C. So, you would get √200=√c² which would equal 14.1 inches. Then, if needed to check the answer, plug the 10,10,and 14.1 back into the a²+b²=c² and it should make the statement true.

mr Goodwill [35]

Given the points A and B

The coordinates of point A = ( 3 , 1 )

The coordinates of point B = (-1 , -1)

The midpoint of AB, is the point C

C will be calculated as following :

$C=\frac{A+B}{2}=\frac{(3,1)+(-1,-1)}{2}=\frac{(3-1,1-1)}{2}=\frac{(2,0)}{2}=(1,0)$

so, the midpoint of AB = (1 , 0 )

A model rocket is launched with an initial velocity of 250 ft per second. The height h, in feet, of the rocket t seconds after t

Answer:

{2.96, 12.66}

Step-by-step explanation:

A graph shows the rocket will be 600 feet up after 2.96 seconds, and again at 12.66 seconds.

You can solve the equation h = 600 to find the times.

-16t^2 +250t = 600

-16(t^2 -15.625t) = 600

-16(t^2 -15.625t +7.8125²) = 600 -16(7.8125²)

-16(t -7.8125)² = -376.5625

t -7.8125 = √(376.5625/16) ≈ ±4.8513

t = 7.8125 ± 4.8513 ≈ {2.9612, 12.6638}

The rocket will be 600 ft above the ground 2.96 and 12.66 seconds after launch.
