Answer: Designing things with round parts may require you to know how to calculate a circumference.

Step-by-step explanation:

The curves on a running or race track are halves of a circle. In order for the track to be fair, the curves and lanes have to be laid out properly. The diameter determines the length of the curve, and then the straight-a-ways can be measured at the correct length to get the exact distance needed for the race. The outer lanes are longer than the inner lanes, so the starting lines are adjusted to compensate for that.

The circumference of a tire on a car has to be figured in to the way the odometer counts the milage and how the speedometer displays the vehicle's speed. The engineers who design the vehicle specify a certain size tire with a known diameter and circumference that matched the calibrations of the speedometer. If someone puts a much larger tire on the vehicle, the circumference will be larger, and the revolutions will result in a longer distance traveled and a higher rate of speed than the instruments on the dashboard are showing. If the circumference is 10% larger, and the driver thinks he is doing 73 mph but he is actually doing 80, he could be surprised when the state trooper pulls him over for 10 mph over the 70 mph speed limit.

Answer:

Circumference being the distance around a circle, can be applied to any life cycle. ... At school we used a Venn Diagram which is two intersecting circles. Venn diagrams were invented by a guy John Venn as a way of picturing relationships between different groups of things.

What is the vertex of the graph of y = 1/3 (x-9)2 + 5 Question 1 options: (9,5) (3,3) (3,5) (-9,5)
svlad2 [7]
ANSWER

The vertex of the graph of
y =  \frac{1}{3}  {(x - 9)}^{2}  + 5
is

(9,5)



EXPLANATION

The vertex form of a parabola is given by

y = a {(x - h)}^{2}  + k

where
V(h,k)
is the vertex of the parabola.


The function given to us is

y =  \frac{1}{3}  {(x - 9)}^{2}  + 5
This is already in the vertex form.


When we compare this to the general vertex form, we have,

a =  \frac{1}{3}

h = 9
and

k = 5


Therefore the vertex of the parabola is

V(9,5)

Hence the correct answer is option A.

Which parent function is f(x) = |x|?
Levart [38]

Answer:

B. The absolute value parent function

Step-by-step explanation:

f(x)=|x|

Referred to as absolute value, the value inside the bars is measured in terms of its distance from 0. Therefore:

|0|=0\\|3|=3\\|-3|=3

In essence, a negative value within the bars becomes positive, while a positive value remains positive.

Ok so the first thing to do would be get rid of the fraction. To do that multiply the ENTIRE equation but the denominator. Once all the numbers are multiplyed I think it’ll be easier for u to solve them :) or if u wanna solve them quick, download Photomath :)
