Find the area of the shaded region. With steps

Mathematics
1 answer:
Agata [3.3K]3 years ago
4 0

Answer: the area of the shaded region is 21.5 cm²

Step-by-step explanation:

The formula for determining the area of a circle is expressed as

Area = πr²

Where

r represents the radius of the circle.

π is a constant whose value is 3.14

From the information given,

Diameter of circle = 10 cm

Radius = diameter/2 = 10/2 = 5 cm

Area of circle = 3.14 × 5² = 78.5 cm²

The length of each side of the square is 10 cm. The area of the square would be

10² = 100 cm²

Therefore, the area of the shaded region would be

100 - 78.5 = 21.5 cm²

Use the definition to find an expression for the area under the curve y = x3 from 0 to 1 as a limit. lim n→∞ n i = 1 R (b) The f
Harlamova29_29 [7]

The summand (R?) is missing, but we can always come up with another one.

Divide the interval [0, 1] into n subintervals of equal length \dfrac{1-0}n=\dfrac1n:

[0,1]=\left[0,\dfrac1n\right]\cup\left[\dfrac1n,\dfrac2n\right]\cup\cdots\cup\left[1-\dfrac1n,1\right]

Let's consider a left-endpoint sum, so that we take values of f(\ell_i)={\ell_i}^3 where \ell_i is given by the sequence

\ell_i=\dfrac{i-1}n

with 1\le i\le n. Then the definite integral is equal to the Riemann sum

\displaystyle\int_0^1x^3\,\mathrm dx=\lim_{n\to\infty}\sum_{i=1}^n\left(\frac{i-1}n\right)^3\frac{1-0}n

=\displaystyle\lim_{n\to\infty}\frac1{n^4}\sum_{i=1}^n(i-1)^3

=\displaystyle\lim_{n\to\infty}\frac1{n^4}\sum_{i=0}^{n-1}i^3

=\displaystyle\lim_{n\to\infty}\frac{n^2(n-1)^2}{4n^4}=\boxed{\frac14}

A culture started with 6,000 bacteria. After 6
aivan3 [116]

Answer:

9,400 bacteria at Hour 17.

Step-by-step explanation:

If at

Hour 0, it was at 6,000 bacteria then at

Hour 6, it would be at 7,200 bacteria

That means in 6 hours, the bacteria has grown by 1,200

Let's use a ratio:

hours : bacteria

   6     :   1,200

   1      :     200

  17     :   3,400

Now after 17 hours, 3,400 new bacteria has joined our group of 6,000

6000+3400=9400

9,400 bacteria should be present at Hour 17

For this question you have to solve the equation backwards.
A = 1/2 x (b1 + b2) x h
In order to get rid of the 1/2 (since it's division) multiply each side by 2
now we have: 2A = (b1 + b2) x h
Now do the same to the get rid of the (b1 + b2) (divide each side by it)
2A/(b1 + b2) = h
