<span>a)
Acceleration of stone = 10
Integrate:
So velocity = 10t
Integrate again:
So distance from starting point = 5t^2
Distance from ground = 450-5t^2
b)
450 - 5t^2 = 0
9.48 seconds
c) velocity = 10t
Put the time into this to give:
94.8 m/s
d.
Velocity = 10t + 5
Integrate again:
5t^2 + 5t
Solve
5t^2 + 5t = 450
Gives 9 seconds</span>
Answer:
a. FG ≈ 6.983 cm
b. FH = 13.16 cm
Step-by-step explanation:
<h3>a)</h3>
Corresponding sides of similar triangles are proportional. This means ...
FG/GH = CD/DE
FG = GH(CD/DE) = (9.4 cm)(2.6/3.5) . . . . . . multiply by GH; fill in values
FG ≈ 6.983 cm
__
<h3>b)</h3>
And ...
FH/GH = CE/DE
FH = GH(CE/DE) = (9.4 cm)(4.9/3.5)
FH = 13.16 cm
__
<em>Additional comment</em>
Corresponding vertices are listed in the same order in the similarity statements. This means, for example, segment FG (which names the first two vertices in the name of ΔFGH) will correspond to segment CD (which names the first two vertices of ΔCDE).
Answer:
the answer for X is -6
Step-by-step explanation:
g(X)=5/2x -1 and g(X)= - 1
sub -16 on g(X)
-16=5/2x -1
-16+1 = 5/2x
-15 = 5/2x
divide both sides by 5/2
X= -6
Answer:
the answer is D
Step-by-step explanation:
(4y-3)(2y²+3y-5)
First , let's start with "4y"
4y*2y² = 8y³
4y*3y = 12y²
4y*-5 = -20y
Next, let's multiply by "-3"
-3*2y² = -6y²
-3*3y = -9y
-3*-5 = 15
Now, let's combine all of our values.
8y³+12y²-6y²-20y-9y+15 = 8y³+6y²-29y+15
