Answer:
6 3/4
Step-by-step explanation:
Since no base is stated, assume base 10
remember
loga-logb=log(a/b)
also
translates to
and log(a^z)=zlog(a)
log25x-log5=2 means
translates to
simplies to
translates to
expands to
100=5x
divide both sides by 5
20=x
Answer:
235or 236
Step-by-step explanation:
A cone has a radius of 5 cm
a height of 9 cm
Volume of cone =1/3πr^2h
=1/3×3.14×5×5×9
= 3.14×25×3
=3.14×75
=235.5
=235or 236 is the answer
8.5 feet(12 inches per foot)= 102 inches total
There are 102 inches in 8.5 feet
Answer:
y=2x-46
Step-by-step explanation:
Select any two coordinate points. I'm picking (1,-44) and (2, -42).
x1 and y1 are the first coordinates. x2 and y2 are the second coordinates. The formula for finding the slope of a linear fuction is (y2-y1)/(x2-x1). Substiute the numbers into this formula:
-42-(-44)/2-1
=-42+44/1
=2
This is the slope. In y=mx+b, plug in your newly found slope. Next, to find the y-intercept, plug any pair of coordinate points into your incomplete formula y=2x+b. I'm going to use (1,-44) again.
-44=2(1)+b
-44=2+b
b=-46
Now, plug this into your formula, and you'll get y=2x-46.
