Answer:
5
Step-by-step explanation:
25 computers in 5 classrooms = 5 computers per classroom
with given condition if there are equal computers in all classrooms
Option D: is the x-coordinate
Explanation:
It is given that the coordinates of the line segment are A(3,2) and B(6,11).
Since, the line is partitioned by the point C by the ratio AC : BC = 2 : 3
The distance between the x-coordinates is 3 units.
To determine the value of the x-coordinate for point C, let us divide the value of x-coordinate from the ratio divided by the sum of ratio.
The value of x-coordinate from the ratio is 2.
Sum of the ratio is 2 +3 = 5
Thus,
The x - coordinate = value of x-coordinate from the ratio / Sum of ratio = 2/5
Substituting the values, we have,
The x - coordinate of the Point C =
Thus, Option D is the correct answer.
Answer:
A. y= 2(x - 2)2 + 4
Step-by-step explanation:
vertex having an x value of 2 means the phrase in paren must be x - 2.
This eliminates B and D
vertex having a y value of 4 is of no help as the remaining two equations will result in 4 if the x term is 2
plugging in x = 3 makes y = 6 in equation A, but not in equation C where y = 10
Answer:
The arc measure of BC is 64
Step-by-step explanation:
1. Calculate the full circumference of the circle
C=2pir
=2pi(18)
=36pi
2. Figure out the arc measure
arc length/circumference=arc measure/degrees in a circle
14pi/36pi=arc measure/360 (solve for arc measure)
14pi/36pi *360=140
The measures of BC and CA add up to the measure of BA
mBC +76=140
BC=64
Answer:
Step-by-step explanation:
You could say that since h(x) is one-to-one, it must have an inverse. And since h is one-to-one, it's inverse must also be one to one.
