Fractions are represented as a ratio of two integers. The ratio of students selected to those trying out is 1:3

Fractions are represented as a ratio of two integers

Total student that tried out cheerleading squad. = 12 students

Total students that were selected = 4 students

The ratio of student selected to those trying out = 4:12

Ratio  = 1: 3

Hence the ratio of students selected to those trying out is 1:3

Answer:

1) Missing Length: 20 m

Equation: [tex]c^2=16^2+12^2[/tex]

2) Missing Length: 100√5 mm

Equation: [tex]c^2=100^2+200^2[/tex]

Step-by-step explanation:

1) We can use Pythagorean Theorem to solve this triangle and find the length of the hypotenuse.

[tex]c^2=16^2+12^2[/tex]

[tex]c^2=256+144[/tex]

[tex]c^2=400[/tex]

Luckily, 400 is a perfect square :)

[tex]c=20[/tex]

So, the length of the hypotenuse is 20 cm.

2) Again, we can use the Pythagorean Theorem to find the missing length.

[tex]c^2=100^2+200^2[/tex]

[tex]c^2=10000+40000[/tex]

[tex]c^2=50000[/tex]

[tex]c=\sqrt{50000}[/tex]

But, we can still simplify the radical.

[tex]\sqrt{50000}[/tex]

[tex]=100\sqrt{5}[/tex]

So, the length of the missing length is 100√5 cm.

Answer:

Answer:

[tex]f(g(-4)) = 18[/tex]

Step-by-step explanation:

Given

[tex]f(x) = 4x + 6[/tex]

[tex]g(x) = x^2 + x - 9[/tex]

Required

Find f(g(-4))

First, calculate f(g(x))

We have:

[tex]f(x) = 4x + 6[/tex]

[tex]f(g(x)) = 4g(x) + 6[/tex]

Substitute: [tex]g(x) = x^2 + x - 9[/tex]

[tex]f(g(x)) = 4[x^2 + x - 9] + 6[/tex]

Open bracket

[tex]f(g(x)) = 4x^2 + 4x - 36 + 6[/tex]

[tex]f(g(x)) = 4x^2 + 4x-30[/tex]

Substitute [tex]-4[/tex] for [tex]x[/tex]

[tex]f(g(-4)) = 4*(-4)^2 + 4*(-4)-30[/tex]

[tex]f(g(-4)) = 64 -16 -30[/tex]

[tex]f(g(-4)) = 18[/tex]

Answer:

[tex] \displaystyle \frac{dy}{dx} = \frac{2x + 2}{x^3} [/tex]

Step-by-step explanation:

we would like to figure out the derivative of the following:

[tex] \displaystyle \frac{ { 3x }^{2} - 2x - 1 }{ {x}^{2} } [/tex]

to do so, let,

[tex] \displaystyle y = \frac{ { 3x }^{2} - 2x - 1 }{ {x}^{2} } [/tex]

By simplifying we acquire:

[tex] \displaystyle y = 3 - \frac{2}{x} - \frac{1}{ {x}^{2} } [/tex]

use law of exponent which yields:

[tex] \displaystyle y = 3 - 2 {x}^{ - 1} - { {x}^{ - 2} } [/tex]

take derivative in both sides:

[tex] \displaystyle \frac{dy}{dx} = \frac{d}{dx} (3 - 2 {x}^{ - 1} - { {x}^{ - 2} } )[/tex]

use sum derivation rule which yields:

[tex] \rm\displaystyle \frac{dy}{dx} = \frac{d}{dx} 3 - \frac{d}{dx} 2 {x}^{ - 1} - \frac{d}{dx} {x}^{ - 2} [/tex]

By constant derivation we acquire:

[tex] \rm\displaystyle \frac{dy}{dx} = 0 - \frac{d}{dx} 2 {x}^{ - 1} - \frac{d}{dx} {x}^{ - 2} [/tex]

use exponent rule of derivation which yields:

[tex] \rm\displaystyle \frac{dy}{dx} = 0 - ( - 2 {x}^{ - 1 -1} ) - ( - 2 {x}^{ - 2 - 1} )[/tex]

simplify exponent:

[tex] \rm\displaystyle \frac{dy}{dx} = 0 - ( - 2 {x}^{ -2} ) - ( - 2 {x}^{ - 3} )[/tex]

two negatives make positive so,

[tex] \displaystyle \frac{dy}{dx} = 2 {x}^{ -2} + 2 {x}^{ - 3} [/tex]

by law of exponent we acquire:

[tex] \displaystyle \frac{dy}{dx} = \frac{2 }{x^2}+ \frac{2}{x^3} [/tex]

simplify addition:

[tex] \displaystyle \frac{dy}{dx} = \frac{2x + 2}{x^3} [/tex]

and we are done!

Answer:

4.4 gibrayets should be it

Answer: Equation; h = -16x² + 280x + 130

Part A.) It was 130 ft high

Part B.) Substitute 0 in for each x given in the equation, then height, (h) would equal to 130.

Part C) Maximum = (8.75, 1355): it could be found using the formula of -b/2a, to find the x-value of the maximum, and then substituting the x-value in the equation in place of x, to find the y-value

Part D) I tried graphing the point (13.6, 0) in the graph and it doesn't show me anything significant, maybe u can ask this one to from teacher? (sorry bout that)

Hope this helps!
