Answer: B

Step-by-step explanation:

because in A it says 2=3 and 2=2 that is not a function each number has to have an outcome of one possible answer if that is true it is a function.

Answer:

$\frac{64}{49}$

Step-by-step explanation:

As we can see the given expression as three complex parts and all are being multiplied.

Lets simplify each part separately and then multiply all of them in the end

Part1

$(\frac{8.4.2}{8.7})^{2}$

Cancelling 8 in numerator with 8 in denominator

$(\frac{4.2}{7})^{2}$

$(\frac{8}{7})^{2}$

$\frac{64}{49}$

Part2

$(\frac{8^{0} }{7^{-3} })^{3}$

simpliying

$(\frac{1}{7^{-3} })^{3}$

$({7^{3} })^{3}$

$7^{9}$

Part3

Third part is $7^{-9}$ , and it does not need to be further simplified

Now multiplying all the three parts

$\frac{64}{49}.7^{9}.7^{-9}$

$\frac{64}{49}.7^{9-9}$

$\frac{64}{49}.7^{0}$

$\frac{64}{49}.1$

$\frac{64}{49}$

So our final answer is $\frac{64}{49}$

The area of square LMNP is 50

<h3>What is a circle?</h3>

A circle is the locus of points equidistant from a fixed point which is known as the center of the circle.

A circle is defined if the center and the radius is known.

Analysis:

Perimeter of a circle = 2πr

Given perimeter = 10π

2πr = 10π

2r = 10

r = 10/2 = 5

r = MO

so the diagonal of the square is actually the diameter of the circle = 5+5 = 10

To find the side, x of the square the diagonal and the sides form a right-angled triangle, by Pythagoras, $10^{2}$ = $x^{2}$ + $x^{2}$

2 $x^{2}$ = 100

$x^{2}$ = 100/2 = 50

Also area of square is $x^{2}$ = 50

In conclusion, the area of square LMNP is 50

if y = 2x + 7 were changed to y = 1/2 x + 7 , how would the graph of the new function compare with the original ?

iris [78.8K]

Y = 2x + 7.....the slope is 2 and the y int is 7
y = 1/2x + 7...the slope is 1/2 and the y int is 7

In comparison, the only difference is the slope. And if the original equation has a slope of 2, and it is changed to a slope of 1/2, then it will have a " less steep " slope. In other words, the slope will not be as steep....but the y intercepts will be the same.

In this problem, volume is computed:

volume = ∫(flow rate)·dt

.. = ∫[0, t] (3/10)*sin(2πt/7)·dt

= (3 / 10)*(7 /(2 π))*(-cos (2 π t/7)+1)

= (-21 / (20 π))*(cos (2 π t /7) - 1)

Volume is equal to 21 sin^2 (pit/7) / 10pi is the inhaled air in the lungs at time t
