My name is Ann [436]2 years ago

I dont think the answer is 129 unless you typed the problem in wrong. Order of operations say to do everything inside the perenthesis first so you would do the 3*2 which is 6 then divide the 12 by 6 and you get 2. so your new equation is 8^2+9(2)-7. Next distribute the 9 to the 2 that is inside the perenthesis. Square root the 8 also. Now it is 49+18-7. The answer would be 60 ...?

Solve for Z 3-4(Z+1)=3Z-(2+Z) Enter you answer as a simple fraction
skelet666 [1.2K]
3 - 4z - 4 = 3z - 2 - z

-4z - 1 = 2z - 2

2z + 4z = -1 + 2

6z = 1

z = 1/6

Hope this helps!

In right triangle ABC, D is the midpoint of the hypotenuse AB. If AD=(5x + 1)cm and CD=(2x + 10)cm, find AB
guapka [62]
Can you confirm is hypotenuse should be AC...

ADB would make another right triangle if I am correct and you could use the pyth theorem to determine AB<span />

Eyjafjallajokull is a volcano in Iceland. In a recent eruption, a projectile is ejected with an initial velocity of 304 feet per
Vikentia [17]

Answer:

A volcano ejected with an initial velocity of 304 feet per second.

The height in feet is given by the equation H=-16t^2+ 304t where t is the time in seconds.

We will use the equation that traces the path of the projectile to determine the following information:

1) The time it takes the projectile to reach its maximum height (using the vertex formula: t=-b/2a)

The equation; H = -16t^2 + 304t, a=-16; b=304

t = -304/2°(-16)

t = 9.5 sec to reach max height

2) The maximum height of the projectile (use the result from part 1 to find the maximum height of the projectile)

t = 9.5

H = -16(9.5^2) + 304(9.5)

h = = -1444 + 2888

h = 1444 ft is the max height

3) Find the time it takes the projectile to return to the ground. Assume that the projectile starts at height H=0.

-16t^2 + 304t = 0

factor out -16t

-16t(t - 19) = 0

t = 19 sec to reach the ground
