Answer:
-1/3 is the slope perpendicular
Step-by-step explanation:
When we have 2 points, we can use the formula
m = (y2-y1)/(x2-x1) to find the slope
m = (1-7)/(3-5)
=-6/-2
=3
The slope is 3
We want a slope perpendicular
Remember that is the negative reciprocal
- (1/3)
-1/3
Answer:
k=10
Step-by-step explanation:
4k + 12= 52
minus 12 on both sides
4k=40
now divide by 4
k=10
Answer:
1.874quartz
Step-by-step explanation:
Since,0.75 gallon=10cabinet
X gallon=25 cabinet
Cross multiply
10x=0.75×25
10x=18.75
Let's make x the subject of formula by dividing both sides by 10
X=1.875
So 10 cabinet=1.875quarts
Answer: 895 phones
Step-by-step explanation:
Given that :
The function : y = 1.28e^1.31x ; is used to model the number of camera phones shipped since 1997
y = number of camera phones ; x = number of years since 1997
The number of camera phones shipped in the year 2002 can be obtained thus ;
x = 2002 - 1997 = 5 years
y = 1.28e^(1.31 * 5)
y = 1.28e^6.55
y = 1.28(699.24417)
y = 895.03254
y = 895 phones
