Answer:
∫₁⁵ 2t (t² + t³) dt
Step-by-step explanation:
The area is ∫ₓ₁ˣ² y dx. To parameterize, replace x₁ and x₂ with t₁ and t₂. Replace y = f(x) with y = f(t), and replace dx with (dx/dt) dt.
x = 5 + t², so dx = 2t dt.
∫₁⁵ (t² + t³) (2t dt)
∫₁⁵ 2t (t² + t³) dt
Answer:
<u>72 cm²</u>
Step-by-step explanation:
Area of a ∆ = 1/2 × b × h
b = 12 cm
h = 12 cm
Area = 1/2 × 12 × 12
= 1/2 × 144
= <u>72 cm²</u>

Answer:
<h3>The ratio of technicians to all helpers is 11 : 7, or
or 11 to 7.</h3>
Step-by-step explanation:
- Given that there are 7 ushers and 11 technicians helping at the Harper Middle School fall play.
- Let x be the number of ushers ( or helpers ).
- Therefore x=7 helpers.
- Let y be the number of technicians.
- Therefore y=11 technicians.
<h3>To find the ratio of technicians to all helpers :</h3>
That is to find the ratio of y to x.
We can write the ratio of technicians to all ushers(helpers) as y : x
Which implies that 11 : 7, (since y=11 and x=7)
Or or 11 to 7
<h3>The ratio of technicians to all helpers is 11 : 7, or
or 11 to 7</h3>
