Answer: the top of the ladder is 15 feet up the wall
Step-by-step explanation:
The attached photo shows the triangle ABC formed by the ladder and the wall. It is a right angle triangle because one of its angles is 90 degrees. The ladder is the hypotenuse of the triangle. To determine how far up the wall that the top of the ladder is,we would find BC by applying Pythagoras theorem
Hypotenuse^2 = opposite ^2 + adjacent^2
17^2 + 8^2 + BC^2
BC^2 = 289 - 64 = 225
BC = √225 = 15
Answer:
(a) 100 fishes
(b) t = 10: 483 fishes
t = 20: 999 fishes
t = 30: 1168 fishes
(c)
Step-by-step explanation:
Given
Solving (a): Fishes at t = 0
This gives:
Solving (a): Fishes at t = 10, 20, 30
Solving (c):
In (b) above.
Notice that as t increases from 10 to 20 to 30, the values of decreases
This implies that:
So:
The value of P(t) for large values is:
Answer:
The length of the flagpole be 41.2 ft .
Option (A) is correct .
Step-by-step explanation:
As given
The angle looking up at the sun is 70°.
A flagpole casts a shadow of 15 ft .
Now by using the trignometric identity .
BC = 15 ft
tan 70° = 2.75 (Approx)
AB = 2.75 × 15
= 41.2 ft
Therefore the length of the flagpole be 41.2 ft .
Option (A) is correct .
