Answer:
It took 14 hours to get out of the well.
Step-by-step explanation:
Consider the provided information.
The well was 70-feet deep, the frog climbs 7 feet per hour, and it slips back 2 feet while resting.
In first hr frog climbs 7 feet and slips back 2 feet, that means it climbs 5 feet in an hour.
In 2 hour it climbs 2 × 5 = 10 feet, in 3 hours it climbs 3 × 5 = 15 feet and so on.
Now we need to find the time taken by the frog to get out of the well.
By observing the above pattern we can say that after 13 hours it can climb 65 feet.
13 × 5 = 65 feet
In next hour frog will climb 65 feet + 7 feet = 72 feet.
That means after 14 hours frog can get out of the well.
Hence it took 14 hours to get out of the well.
Answer:
t = 25.1seconds
Step-by-step explanation:
X(t)= 16cos75°t
Y(t)= 6 + (Vosin75°t - 16t^2)
Converting 78 yards to feet :
1 yard = 3 feet
78feet =?
78×3=234 feet
Y(t)= number of feet above the ground at t seconds
VoCos75° t = 234
t = 234/(VoCos75°)
At this time,4 = y(234/VoCos75°)
4 = 6 + VoSin75°(234/VoCos75) - 16(234/VoCos75°)^2
Vo= 140.66ft/s
Time,t= 234/(140.66× Cos75°)
t = 25.087seconds
t= 25.1 seconds (1 decimal place)

The attached figure represents the array for 237 x 43
<h3>How to draw the array?</h3>
The array is given as:
237 x 43
An array is represented as:
Row x Column
This means that:
Row = 237
Column = 43
i.e. the array has 237 rows and 43 columns
The numbers are large, so the cells would be small when the arrays are drawn
See attachment for the array

Equation:
y - 10 = -5x
Solve:
(y - 10) + 10 = (-5x) + 10
y = -5x + 10
Remember the formula (Slope Intercept Form):
y = mx + b
m = Slope (Rise/Run)
b = Y-intercept
So your graph would look something like the attached image:
