The standard diameter of a golf ball is 42.67 mm. A golf ball factory does quality control on the balls it manufactures. Golf balls are randomly measured to ensure the correct size. One day, an inspector decides to stop production if the discrepancy in diameter is more than 0.002 mm. Which function could represent this situation?A. f(x ) = x – |42.67| B. f(x ) = |x| – 42.67 C. f(x ) = |42.67 – x| D. f(x ) = 42.67 – |x|

Convert the equations into the slope-intercept form y=mx+b.

$10x+5y=4 \n5y=-10x+4 \ny=-2x+(4)/(5) \nm=\boxed{-2} \Leftarrow \hbox{the slope} \n \ny=(x)/(3)-5 \ny=(1)/(3)x-5 \nm=\boxed{(1)/(3)} \Leftarrow \hbox{the slope}$

How do i figure this out?

Answers

Answer:

Slope of function A is greater than slope of function B

Step-by-step explanation:

You calculate the gradient (slope) of function B. That is, change in y divided by change in x.

Take point (0, 1) and (2, 5) from the graph of function B.

change in y = 4

change in x = 2

gradient = 2

b(x) = 2x + 1

Therefore the function B has a lesser slope than function A

Which of the following are the factors of t4 – 81?A. (t – 3)(t + 3)2
B. (t – 3)(t + 3)(t2 + 9)
C. (t2 – 9)(t2 – 9)
D. (t – 3)2(t + 3)2

Answers

$t^4 - 81 =\n\n(t^2)^2 - (9)^2=\n\n(t^2 - 9)(t^2 + 9) =\n\n\boxed{\bf{ (t-3)(t+3)(t^2 + 9)}}$

Your answer is B.

$t^4 - 81 \n \n (t^2)^2 - 9^2 \n \n (t^2 + 9)(t^2 - 9) \n \n (t^2 + 9)(t^2 - 3^2) \n \n (t^2 + 9)(t + 3)(t - 3) \n \n$

The final result is: B
