How much fencing is required to enclose a circular garden whose radius is 27 ​meters?

Answer:

D

Step-by-step explanation:

1) if sin(ACB)=BC/BD, then BC=BD*sin(ACB);

2) m(ACB)=60°, then sin(ACB)=√3/2, then

3) BC=5/(√3/2)=10/√3 or 10√3/3.

Answer:

600 m³

Step-by-step explanation:

The shape we have is a rectangular pyramid:

Formula: (volume of a rectangular pyramid)

Volume = (1/3) × Base Area × height

___________________________

In our case :

Base area = L × W = 20 × 18 = 360 m²

height = 5 m

⇒ Volume = (1/3) × Base Area × height

    [tex]\Longrightarrow \text{volume} \ =\ \frac{1}{3} \times 360\times 5[/tex]

[tex]\Longrightarrow \ \text{volume} \ =\ 600\ m^{3}[/tex]

Answer:

No.

Step-by-step explanation:

It's simpler than you might expect.

If [tex](x - 4)[/tex]  is a factor, then it means that it the function [tex]f(x) = x^3 - 2x^2 + 5x + 1[/tex] can have [tex](x - 4)[/tex] factorised out.

This means that we can say [tex](x - 4) = 0[/tex]

Therefore [tex]x = 4[/tex]

If we put [tex]x = 4[/tex] into the equation:

[tex]f(4) = (4)^3 - 2(4)^2 + 5(4) + 1\\= 64 - 32 + 20 + 1\\= 53[/tex]

We didn't get 0, therefore it isn't a factor!

Riya have 20 apples

Step-by-step explanation:

Let, Tyler have x apples

Then, Riya have 5x apples

Now, From the question,

5x + x =24

or, 6x =24

or, x = 24/6

or, x = 4

Tyler have 4 apples

Again,

Riya have 5x apples

=5*4

=20

Therefore, Riya have 20 apples

Answer:

A = 52º AND B=38º

Step-by-step explanation:

Let's call A and B the two angles.

First condition: A + B = 90º

Second cond: A + 2B = 128º

Subtract the first condition to the second: B = 38º

Replace the value of B in any of the 2 conditions; e.g. in the first.

A + 38º = 90º

A = 90º - 38º = 52º

It would take 6 people to build the wall 1 day

It takes 4 days to build the same wall with 6 people based on the given ratio.

The ratio is the division of the two numbers.

Proportion is the relation of a variable with another. It could be direct or inverse.

As per the given,

It takes 4 people 6 days to build a wall.

The number of people days taken = 4 x 6 = 24 people takes

This means if one person wants to build them it takes 24 days.

For 6 people the time taken will be 24/6 = 4 days.

Hence "It takes 4 days to build the same wall with 6 people based on the given ratio".

We can write the log expression in terms of the log of x, y, and z as expression 1/2(logx+2logy-8logz).

It is another way to represent the power of numbers and we say that 'b' is the logarithm of 'c' with base 'a' if and only if 'a' to the power 'b' equals 'c'.

[tex]\rm a^b = c\\\\log_ac = b[/tex]

We have an expression in logarithm:

[tex]=\rm log\sqrt{\frac{xy^2}{Z^8} }\\\\=log(\frac{xy^2}{Z^8})^{\frac{1}{2} }\\\\=\frac{1}{2}log(\frac{xy^2}{Z^8})[/tex]                         [tex](\rm loga^b = (b)log(a))[/tex]

[tex]\rm\frac{1}{2} (log(xy^2)-logz^8)[/tex]              [tex](\rm log(\frac{a}{b} )= loga - logb)[/tex]

[tex]\rm\frac{1}{2} (log(x)+log(y^2)-logz^8)[/tex]   [tex](\rm logab = loga+logb)[/tex]

[tex]\rm\frac{1}{2} (log(x)+2log(y)-8logz)[/tex]

Thus, we can write the log expression in terms of the log of x, y, and z as 1/2(logx+2logy-8logz).

Answer:

The y-intercept is the point (0, 128).

The x-intercepts are the points (-4, 0) and (-8, 0).

As x → ∞, y → ∞.

As x → -∞, y → -∞.

Step-by-step explanation:

To find the y-intercept, substitute 0 for x and solve for y.

The y-intercept is (0, 128).

To find the x-intercept, substitute 0 for y and solve for x.

Set the first term, (x + 4)², equal to 0.

Set the second term, (x + 8), equal to 0.

The x-intercepts are the point (-4, 0) and (-8, 0).

Look at the degree and leading coefficient of the polynomial to determine the end behavior, and therefore you can determine how y behaves as x gets closer to infinity.

Since the degree of the polynomial is odd (3) and the leading coefficient is positive, the graph falls to the left and rises to the right.

So, as x → ∞, y → ∞ and as x → -∞, y → -∞.

If you want to verify this, plug the equation into your calculator and look at the graph. How does it behave as you look at negative x-values? How about for positive x-values?

Step-by-step explanation:

1st year depreciation = 141000 -  (141000 * 0.016) = 138744

2nd year depreciation = 138744 - (138744 * 0.016) = 136524.096

3rd year depreciation = 136524.096 - (136524.096 * 0.016) = 134339.710464

Basically we calculate 1.6% of the current value of the house and subtract that from the current value for each year for 15 years.

The equation used in the answer is a faster way to approach your answer instead of calculating for each year.

You'd multiply your initial value by the difference in percentage (note well that since it is decreasing in value we subtract the decimal equivalent to 1.6% which is 0.016, from 1 where one represents 100% and then raise the difference gained to the power of the amount of years which would be 15.
