Answer: 9 seconds
Step-by-step explanation:
When the object hit the ground,
Height h = 0
Therefore,
h(x)= -5(x+1)(x-9) = 0
0 = -5(x+1)(x-9)
Open the bracket
0 = (-5x - 5)( x - 9)
0 = -5x^2 + 45x - 5x + 45
0 = -5x^2 + 40x + 45
Divide all by -5
0 = x^2 - 8x - 9
Factorizing the equation gives
(x + 1)(x- 9)
x = -1 or 9
Since Time can't be negative
Therefore, the time seconds after launch the object will hit the ground is 9 seconds
Answer:
h=5
Step-by-step explanation:
Let's solve your equation step-by-step.
5h−13=12
Step 1: Add 13 to both sides.
5h−13+13=12+13
5h=25
Step 2: Divide both sides by 5.
5h
/5
=
25
/5
h=5

Answer:
The correct answer is C
Step-by-step explanation:
The given circle is centered at A(3, 1) and passes through the origin (0, 0).
The radius of this circle can be found using the distance formula;
.
.
.
.
.
The equation of this circle is given by
Where is the centre.
We substitute the center and radius to obtain;
Option A
When we substitute (2,-2) into this equation we get;
This is true
Option B
When we substitute K(6,0), we get,
This is also true
Option C
We substitute L(4,-4) to get;
This is false. Hence L(4,-4) does not lie on the circle.
Option D
We substitute M(2,4)
This is also true.
The correct answer is C
Answer: 3360 ft squared
Step-by-step explanation:
Short side : 30 x 14 = 420
Long side 30 x 3 x 14 = 1260
420 + 420 + 1260 + 1260 = 3360
