What is the area of the shaded region?

Tresset [83]

Answer:

$21.5 \: {cm}^{2}$

Step-by-step explanation:

Area of the shaded region =Area of square with side 10 cm - Area of circle with radius 5 cm

$= {10}^{2} - 3.14 {(5)}^{2} \\ = 100 - 3.14 \times 25 \\ = 100 - 78.5 \\ = 21.5 \: {cm}^{2}$

Simplify this expression: cos theta/ tan theta cot theta

Dmitry_Shevchenko [17]

Q: $\frac{cos\theta}{tan\theta.cot\theta}=?$

A:

$\frac{cos\theta}{tan\theta.cot\theta}=cos\theta$

because... $tan\theta.cot\theta=1$
*********************************************************
Q: $\frac{cos\theta}{tan\theta}.cot\theta=?$

A:

$\frac{cos\theta}{tan\theta}.cot\theta&= \\ \\ \frac{cos\theta}{\frac{sin\theta}{cos\theta}}.\frac{cos\theta}{sin\theta}&= \\ \\ \frac{cos^2\theta}{sin\theta}}.\frac{cos\theta}{sin\theta}&= \\ \\ \frac{cos^3\theta}{sin^2\theta}}&= cos^3\theta.cosec^2\theta$

F(x) = 32x

Delvig [45]

Answer:

Option A is the correct answer

Step-by-step explanation:

$f(x)=\sqrt[3]{2x}$

$g(x)=4x+1$

$\bigg(\frac{f}{g}\bigg)(x)=\frac{\sqrt[3]{2x}}{4x+1},\:x\neq -\frac{1}{4}$

Because by plugging x = -1/4 denominator of the fraction would become zero.

Division by zero is not defined.

Given that B is between A and C. If AB=x, BC =2x-3, and AC = 30. Find x and bc

Artemon [7]

Answer:

x=11

BC=19

Step-by-step explanation:

AB+AC=AC this is because B is in between A and C. So now we can substitute all of the line segments, so we have

x+2x-3=30 Now you add 2x and x

3x-3=30 Now you add 3 to both sides so you can get 3x alone on one side

3x=33 Now you divide both sides by 3 so you get the x alone on one side

x=11

The next step is to substitute x to find BC.

BC=2x-3 Substitute the x with 11

BC=2(11)-3 Then multiply 2 and 11 because that is the rule with parenthesis

BC=22-3 then subrtact the 3 from 22

BC=19

You can check your work by doing AB+BC=AC

11+19=30 substitute your answers and then add them together

30=30

The water works commission needs to know the mean household usage of water by the residents of a small town in gallons per day.

mote1985 [20]

The confidence interval for the mean usage of water is (18.7,20.5).

Given population standard deviation of 2.4, mean of 19.5 gallons per day and confidence interval of 98%.

We have to find the confidence interval for the mean usage of water.

To find out the confidence interval we have to first find margin of error.

μ=19.5

σ=2.4

α=0.98

α/2=0.49

We have to find the z value for the p value 0.49 which is z=2.33

Margin of error=z*μ/ $\sqrt{n}$

=2.33*19.5/ $\sqrt{3034}$

=0.82

lower level=mean -m

=19.5-0.82

=18.68

after rounding upto 1 decimal

=18.7

upper mean = mean+m

=19.5+0.82

=20.52

Hence the confidence interval for the usage of water is (18.7,20.52).
