Arlecino [84]4 years ago

Answer:

50.24

Step by Step explanation:

The area of a circle is pi r squared. But, we're given the diameter. The diameter is just 2 times the radius, so the radius is 8 / 2 = 4. Now, we can plug this into our formula, and get that the area of the circle is 4^2 * pi. assuming pi is 3.14, as told, we get 16 * 3.14 which is 50.24.

I’m Atlanta, the tax on a property assessed at $930,000 is $19,530. If tax rates are proportional in this city, how much would t
igomit [66]

Answer:

The tax on property assessed at $660,000 is  <u>$13860 </u>.

Step-by-step explanation:

Given:

In Atlanta the tax on a property assessed at $930,000 is $19,530.

The tax rates are proportional to this city.

Now, to find the tax on a property assessed at $660,000.

So, <em>we need to get the tax rate of Atlanta first.</em>

Tax Rate = Tax / Property assessed × 100.

Tax\ rate=\frac{19530}{930000} \times 100

Tax\ rate=0.021 \times 100

Tax\ rate=2.1\%

<em>According to question the</em><u><em> tax rates are proportional.</em></u>

<em>So, </em><u><em>for getting the tax in this city we use the same rate of Atlanta</em></u><em>:</em>

Tax = tax rate of property assessed.

Tax = 2.1\% of\ \$660,000

Tax = \frac{2.1}{100}\times 660000.

Tax = 0.021\times 660000

Tax=\$13860

Therefore, the tax on property assessed at $660,000 is $13860.

A dog is tied to a leash on a tree and the leash is 10 meters long. There is a bone 15 meters away but the dog easily gets the b
Alex17521 [72]

Answer:

One way the dog can easily reach the bone is given by the relationship between the dog, the tree, and the bone

The dog can easily reach the bone when the tree is between the the dog and the bone, and the dog was more than 5 meters behind the tree

Therefore the distance the dog can reach in the direction of the bone from its position behind the tree is more than 15 meters and the dog can easily get the bone while the leash is not harmed

If f(x) = 3x2 − 8x, 0 ≤ x ≤ 3, evaluate the Riemann sum with n = 6, taking the sample points to be right endpoints.
denis23 [38]

Split up the interval [0, 3] into 6 subintervals,

[0, 1/2], [1/2, 1], [1, 3/2], [3/2, 2], [2, 5/2], [5/2, 3]

The right endpoints are given by the arithmetic sequence,

r_i=0+\dfrac i2=\dfrac i2

with 1\le i\le6.

We approximate the integral of f(x) on the interval [0, 3] by the Riemann sum,

\displaystyle\int_0^3f(x)\,\mathrm dx=\sum_{i=1}^6f(r_i)\Delta x_i

\displaystyle=\frac{3-0}6\sum_{i=1}^6\left(3{r_i}^2-8r_i\right)

\displaystyle=\frac12\sum_{i=1}^6\left(\frac{3i^2}4-4i\right)

\displaystyle=\frac38\sum_{i=1}^6i^2-2\sum_{i=1}^6i

Recall the formulas,

\displaystyle\sum_{i=1}^ni=\frac{n(n+1)}2

\displaystyle\sum_{i=1}^ni^2=\frac{n(n+1)(2n+1)}6

Then the value of the integral is approximately

\displaystyle=\frac38\cdot\frac{6\cdot7\cdot13}6-2\cdot\frac{6\cdot7}2=\boxed{-\frac{63}8}=-7.875

Compare to the exact value of the integral, -9.
