Given the definitions of f(x) and g(x)
below, find the value of f(g(-4)). F(x)=4x+6 g(x)=x^ 2+x-9
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:
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.

ABC city residents vote on construction of a new playground. The number of votes in favor of playground was 3500
and the votes against it were 1500. What percent of the votes were in favor of building a new playground?
NEED ASAP
Answer:
70% in favor of building a new playground
3500 (in favor) + 1500 (against it) = 5000 (total number votes)
3500 (in favor) 1500 (against it)
------------------- = 0.7 / 70% ------------------- =0.3 / 30%
5000 (total) 5000 (total)

Then you subtract and boom 3/4 it also says in the problem lol
A projectile’s height is given by the equation ℎ=−16^2+280+130, where h represents the height, in feet, t seconds after it was launched.
Part A. How high was the projectile when it was launched?
Part B. How do you know?
Part C. Determine algebraically the maximum height of the projectile.
Part D. The point (13.6, 0) represents a key feature for this projectile. What is its significance in the context of this problem?
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)

Answer:
34.3
Step-by-step explanation:
Answer: The answer is (34.3)
Step-by-step explanation:
Since you're rounding to the nearest tenth, you gotta look at the hundreds place which is 8. 8 rounds up so therefore, 2 rounds up and becomes 3. Which gives you the answer (34.3)

derivative of
[tex] \frac{ {3x}^{2} - 2x - 1 }{ {x}^{2} } [/tex]
Show a step.
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]
further simplification if needed: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!
