Answer:
b=-7
Step-by-step explanation:
if you were supposed t solve for something else just comment and i'll come back :)
(next time state what ur solving for)
The constant of proportionality k is given by k=y/x where y and x are two quantities that are directly proportional to each other. Once you know the constant of proportionality you can find an equation representing the directly proportional relationship between x and y, namely y=kx, with your specific k. (i looked up this explanation but not sure if it’s right.. if it’s wrong let me know:) )
Answer:
Maximum altitude: 497.96 ft
Horizontal range: 1007.37 ft
Speed at impact: 165.21 ft/s
Step-by-step explanation:
angle(α) = atan (7/6) = 49.4°
Maximum altitude is given by the formula:


Horizontal range is given by the formula:


Speed at impact is given by the formula:

where:



So;


<u>Answer:</u>
The height of the model is 2 feet 10.5 inches.
<u>Step-by-step explanation:</u>
<u>Given:</u>
scale of 1/3 inch=2ft
actual tower is 207 feet
<u>To Find:</u>
The height of the model = ?
<u>Solution</u>:
We know that 1 feet is 12 inches
Then 2 feet is
= 24 inches
24 inches=
of a inch.
The tower is 72 times the scale of the model.
Now the actual tower is 207 feet
=
, units feet
=> 
=> 2 feet 10.5 inches.
15%= .15
.15*22= 3.3
Answer: 3.30
