Solutions
- ANS-cylinder
A line passes through the point
−−3, 7 and has a slope of
2
Write an equation for this line.
Y=MX+B
m=2 it is the slope
plug x and y in - ANS-y=2x-1
rewrite as an exponential equation
LOG2(1/2) = -1 - ANS-LOG2(1/2) = -1
log aC=b if a^b=c
answer is 2^-1=1/2
Calculate the distance between the points c=, (2,−2) and p=( 7,−6) in the coordinate
plane.
Give an exact answer (not a decimal approximation).
d= square root of: (x2-x1)^2 + (y2-y1)^2
answer is the square root of ____ - ANS-41
Graph the solution to the inequality on the number line.
|v+6| >. 2
-
v+6>2 V+6<-2 - ANS-
UNION = U IT MEANS AND what applies to both categories
upside down U means OR
The sets I and F are given below.
=I=1,2,3,5
=F=−2,1,3,4,5
Find the union of I and F.
Find the intersection of I and F.
Write your answers using set notation (in roster form).

The height (in centimeters) of a candle is a linear function of the amount of time (in
hours) it has been burning. When graphed, the function gives a line with a slope of
−0.4
Suppose that the height of the candle after
12 hours is 22.2 centimeters.
What was the height of the candle after
9 hours? - ANS-12-9=3
3x slope(-0.4)= -1.2
since it is 9 hours and the candle should be longer, add it to 22.2
22.2 + 1.2 = 23.4
Calculate the distance between the points
G = (2,−2)
and
F = (9,−6)
in the coordinate plane.
Give an exact answer (not a decimal approximation). - ANS-D = square root of (x2-
x1)^2 + (y2-y1)^2
4√243
1. write all powers of 4
4√81 x 3
4√3^4 x 3
3X square root of 4 x 3 - ANS-3X square root of 4 x 3
solve for x in the triangle.
tan (given angle ) = x/14
x = tan(70 degrees) x 14 - ANS-
Graph the solution to the inequality on the number line.
|x+4| ≤ 4
= |x+4| ≤ 4 or |x+4| ≥ -4
there should only be one solution that applies to BOTH
