Triangle

Area = 1/2 b * h

Area = 1/2*15 * 9 = 1/2 * 135 = 67.5

Rectangle

Area = b * h

Area = 15 * 4

Area = 60

Trapezoid

Area = (1/2) * (b1 + b2)* h

Area = (1/2) * (15 + 18) * 4

Area = 1/2 * 33 * 4

Area = 66

Total Area

Total Area = 66 + 60 + 67.5 = 193.5 Answer

Find the area under the curve y = 27/x3 from x = 1 to x = t. Evaluate the area under this curve for t = 10, t = 100, and t = 100
Darina [25.2K]

Answer:

Step-by-step explanation:

given is a function as

y=\frac{27}{x^3}

We are to find the area form x=1 to x=t

The curve from x=1 lies in the I quadratnt.

So area  above x axis is to be calculated

Area = \int\limits^t_1 {\frac{27}{x^3} } \, dx \\=\frac{-27}{2x^2} \\= \frac{-27}{2t^2}-\frac{-27}{2}\\=\frac{27}{2}(1-\frac{1}{t^2} )

a) When t =10,

area = \frac{27}{2} (1-\frac{1}{10^2} )\\= 13.365

b) t=100

area = \frac{27}{2} (1-\frac{1}{100^2} )\\= 13.49865

c) t=10000

area = \frac{27}{2} (1-\frac{1}{10000^2} )\\= 13.5

The largest taco contained approximately 1 kg of onion for every 6.8 kg grilled steak. The total weight of these two ingredients
erastovalidia [21]

Answer: Onion = 79.17 kg

Grilled steak = 538.356 kg

Step-by-step explanation:

Hi, to answer this question we have to write an equation with the information given:

1 k + 6.8 k = 617.6  

Where “k” is a constant value, a multiplier.

Solving for k:

7.8 k = 617.6

k = 617.6 /7.8  

k= 79.17

So:

Amount of onion used:

1 (79.17) = 79.17 kg

Amount of grilled steak used:

6.8 (79.17) = 538.356 kg

Feel free to ask for more if needed or if you did not understand something.
