Answer:
The approximate speed will be 19 revolutions per minute.
Step-by-step explanation:
In model 5, the length of the blade is 148 feet.
The maximum velocity of the blade tip reaches 200 miles per hour.
Per revolution, the blade tip covers 0.18 mile.
Revolutions per hour can be calculated as = 1,111.
To find the speed per minute, divide by 1 minute (60 seconds).
= 18.51 ≈ 19 revolutions per minute.
Answer:
2.1 miles
Step-by-step explanation:
Refer to the attached illustration (you need to include all the mentioned locations and the distances between them),
enabling us to create a right triangle between the school and the hospital with side measures of: 1.7 and 1.2 miles
and the green line represents the direct path from the school to the hospital; thus, applying the Pythagorean theorem will yield the result:
When rounded to the nearest tenth:
2.1 miles
Response:
= 270 ⇒ Previous solution
Detailed breakdown:
* Given f(x) = 7 + 4x
* Given g(x) =
* We aim to determine
- Initially, let’s calculate
∵ f(x) = 7 + 4x
∵ g(x) =
∴
- Let’s perform division of the numerator by the denominator
∵ The numerator is 7 + 4x
∵ The denominator is
∴ (7 + 4x) ÷
- Now we will change the division sign to a multiplication sign and take the reciprocal of
the fraction following the division sign
∴ (7 + 4x) ×
∴ = 2x(7 + 4x)
∴ = 14x + 8x²
- Next, substitute x with 5
∴ = 14(5) + 8(5)² = 70 + 200 = 270
∴ = 270
