Answer:Therefore, the relationship will be of the form, y = mx + b, or in this case, d = (max distance / max time)t + 0.
Step-by-step explanation:
Answer:
The answer is y = ± ![\sqrt[4]{\frac{x}{4}}](https://tex.z-dn.net/?f=%5Csqrt%5B4%5D%7B%5Cfrac%7Bx%7D%7B4%7D%7D)
, 
is a function ⇒ 1st answer
Step-by-step explanation:
Let us revise the steps of find the inverse of a function
- Replace f(x) with y
- Replace every x by y and replace y by x
- Solve the equation in Step 2 for y
- Replace y by
∵ 
- Replace f(x) by y
∴ 
- Replace y by x and x by y
∴ 
- Divide each side by 4
∴ 
- Take ![\sqrt[4]{}](https://tex.z-dn.net/?f=%5Csqrt%5B4%5D%7B%7D)
for both sides
∴ ± ![\sqrt[4]{\frac{x}{4}}=y](https://tex.z-dn.net/?f=%5Csqrt%5B4%5D%7B%5Cfrac%7Bx%7D%7B4%7D%7D%3Dy)
- Switch the two sides
∴ y = ±
∵ There is no fourth root for negative number
∴ x ≥ 0
When you test the graph of by a vertical line, it will cut it just at one in every position, so it is a function. Look to the attached graph for more understand
∴ is a function
The answer is y = ± , is a function
Area of the sector = 90/360 ×πr^2
=1/4 ×3.142×6×6
=1/4×113.112
=28.278kilometers square
Approximately 28kilometers square
Answer:
a. x = 5, m∠FGH = 22°
b. m∠HGI = 22°
c. m∠FGI = 44°
Step-by-step explanation:
Since GH bisects FGI this means it divides the angle in two equal parts.
a. solving for x means equating them:
5x-3 = 6x-8 =>
5x - 6x = 3 - 8 =>
x = 5.
Both m∠FGH and m∠HGI are 5*5-3 = 22°
c. Add both angles: m∠FGH + m∠HGI = 44°
Perpendicular line: y = 2x+4
parallel line: y = -2x+3 (or any number different from 4)
neither: y= -4x+-3
