Find the area under the curve y = 13/x3 from x = 1 to x = t. Evaluate the area under the curve for t = 10, t = 100, and t = 1000
zvonat [6]

Answer:

t = 10

A = 32496.75

t = 100

A = 324999996.8

t = 1000

A=3.25\times 10^{12}

Step-by-step explanation:

The area under the curve is calculated by using the following definite integral:

A = \int\limits^t_ {1} \,{13\cdot x^{3}}  dx

A = 13 \int\limits^t_1 {x^{3}} \, dx

A = \frac{13}{4}\cdot (t^{4}-1)

Evaluated areas are presented below:

t = 10

A = 32496.75

t = 100

A = 324999996.8

t = 1000

A=3.25\times 10^{12}

A flagpole and a model flag pole have a scale factor of 1 in.= 4 ft. If the model pole measures 12 inches, how tall is the actua
Karolina [17]

Answer:

48\ \text{feet}

Step-by-step explanation:

1\ \text{inch} of the model is 4\ \text{feet} of the actual pole.

Here, the pole which is present in the model measures 12\ \text{inches}, so

12\ \text{inches} of the model will be (12\times 4)\ \text{feet}=48\ \text{feet}

Hence, the actual pole will be \boldsymbol{48\ \text{feet}} tall.

If prices increase at a monthly rate of 2.7 by what do they increase in a year
guapka [62]

Answer:

37.67%

Step-by-step explanation:

Suppose initially a price of $ 100

Increasing per month at a rate of 2.7%. Which is equal to 0.027

Now applying the formula:

Vf = Vi * (1 + m) ^ n

where Vf is the final quantity, Vi is the initial value, m is the rate and n is the number of months.

We know that 1 year, is 12 months, since the rate is monthly means, n = 12, we replace:

Vf = 100 * (1 + 0.027) ^ 12

Vf = 137.67

It means price increase in 1 year = 137.67 - 100 = 37.67

Which means that n a year increases to 37.67%
