Ummm if the numbers are 800 and 12% the answer is 96 students
12/100=x/800
100x=9600
x=96

Are the angles with the given measures complementary, supplementary, or neither?

madam [21]

They're complementary.
Complementary angles are a pair of two angles that add up to a sum of 90 degrees
Supplementary angles add up to 180 degrees
63 + 27 = 90

Write the composite function in the form f(g(x)). [Identify the inner function u = g(x) and the outer function y = f(u).] y = ta

Irina-Kira [14]

Answer:

The inner function is $u = \pi x$ .

The outer function is $f(u) = \tan{u}$ .

$\frac{dy}{dx} = y^{\prime} = \sec^{2}(u)*\pi = \pi\sec^{2}{\pi x}$

Step-by-step explanation:

The inner function is the one we apply the outer function to.

So

$y = \tan{\pi x}$

We apply the outer function tangent to $\pi x$ .

So, the inner function is $u = \pi x$ .

The outer function is $f(u) = \tan{u}$ .

The derivative of a compositve function

$y = f(u)$ in which $u = g(x)$ is given by the following function.

$y^{\prime} = f^{\prime}(u)*g^{\prime}(x)$

So

$f(u) = \tan{u}$

$f^{\prime}(u) = \sec^{2}{u}$

$u = g(x) = \pi x$

$g^{\prime}(x) = \pi$

So

$y^{\prime} = f^{\prime}(u)*g^{\prime}(x)$

$\frac{dy}{dx} = y^{\prime} = \sec^{2}(u)*\pi = \pi\sec^{2}{\pi x}$

Answer:

50-2.5t=w. no, the water will all have drained by then.

Step-by-step explanation:

2.5 per min so

min=t

therefore 2.5t

theres 50 quarts of water

50-2.5t = w (water left in the tank)

_____________________________________-

part 2,

2.5*30 = 75, and 50<75

this is impossible.
