Mathematics
1 answer:
zlopas [31]3 years ago
3 0

Answer:

It will take 3 seconds.

Step-by-step explanation:

All we have to do is plug in the values we have to the equation the question gave us.

We know that the initial velocity or v = 48, and that the height we are trying to reach is =, so h = 0. We are solving for t

h = -16t^2 + vt

0 = -16t^2+48t

We can factor out -16t on the right side of the equation

0 = -16t(t-3)

Then using the zero product property, we can say that either -16t is equal to 0 in which case t is equal to 0 or t-3 = 0, in which case t = 3. We know that the ball had to leave the ground, so it couldn't have taken no time at all to come back onto the ground. Therefore, we know that the other solution is correct.

BThe wooden treehouse has horizontal siding that is parallel to the base. What are the LM and MN to the nearest hundredth?
xeze [42]

Answer:

LM =  2.82 ft

MN =  2.39 ft

Step-by-step explanation:

We suppose ΔGNF is isosceles and GF bisect ∠NGF, so that GK ⊥ NF

LH // MJ // NK

GL / GH = LM / HJ = MN / JK

11.3 / 10.4 = LM / 2.6 = MN / 2.2

LM = 11.3 / 10.4 x 2.6 = 2.82

MN = 11.3 / 10.4 x 2.2 = 2.39

Evan is making a table that will be created in the shape of the figure below. The table top is a triangle attached to a rectangl
emmainna [20.7K]
Area of a triangle:
A (triangle )= 4 · 6 / 2 = 12 ft²
150 - 12 = 138 ft² ( the maximum area of the rectangle )
L = ?
W = 6 ft
A ( rectangle ) = L · W
L · 6 = 138
L = 138 : 6 = 23 ft.
Answer: the maximum length of the base of the rectangle he can build is 23 ft.

RSB [31]

A customer borrowed $2000 and then a further $1000 both repayble in 12 months. What would he have saved if he had taken out one loan for $3000 repayable in 12 months?

He took two different loans, it charged him loan processing fee twice, two-time documentation process, and of course, extra time spent for second loan. Instead, he could take single loan of $3000 with one-time processing fee, one-time documentation process, and time-saving also.
