T = 126.
13 = t/9 - 1 multiply both sides by 9
117 = t - 9 move terms
-t = -9 - 117
-t = -126 change the signs
t = 126
The given question have mistake. The correct question is written below.
Question:
A dog jumps straight up in the air to catch a ball and lands on the ground 6.37 s later. Let h(t) represent the dog’s height, in meters, t seconds after he leaves the ground. Which equation models the dog’s height for a given time t?
Answer:
Option B:

Solution:
<u>General formula for the height of the projectile over time:</u>
(1) 
Where h = height in feet, t = time, v = initial velocity and s = initial height (feet)
(2) 
Where h = height in meters, t = time, v = initial velocity and s = initial height(meter)
Given initial velocity = 6.37 s and initial height is 0.
The height of the dog is in meters.
So, use second formula and substitute v = 6.37 and s = 0.



Hence option B is the correct answer.
Answer:
C=$(4.30xy+5.40(xz+yz))
Step-by-step explanation:
Surface Area of a Cuboid=2(LW+LH+HW)
Since the top is open
Surface Area = LW+2(LH+HW)
If Length = x feet,
Width =y feet
Height = z feet
Surface Area = xy+2(xz+yz)
Area of the base=xy
If it costs $4.30 per square foot to build the base
Cost of the base=Cost Per Square Foot X Area = $4.30xy
Area of the sides =2(xz+yz)
If it costs $2.70 per square foot to build the sides
Cost of the sides=Cost Per Square Foot X Area of the sides
= 2.70 X 2(xz+yz)
=5.40(xz+yz)
Cost of Constructing the Box = Cost of Constructing the Base + Cost of Constructing the Sides.
Therefore,
C=$(4.30xy+5.40(xz+yz))
Answer:
x = 10
Step-by-step explanation:
Since the two triangles are congruent, ∠B ≅ ∠E
50 = 5x
x = 10
