Choose the graph below that has an undefined slope.
Ronch [10]

Answer:

The correct option is A.

Step-by-step explanation:

The first line passing through the points (-6,2) and (-6,0).

The slope of a line is

m=\frac{y_2-y_1}{x_2-x_1}

The slope of first line is

m_1=\frac{0-2}{-6-(-6)}=\infty

The second line passing through the points (0,-4) and (-1,1). The slope of second line is

m_2=\frac{1-(-4)}{-1-0}=-5

The third line passing through the points (0,-6) and (2,-6). The slope of third line is

m_3=\frac{-6-(-6)}{2-0}=0

The fourth line passing through the points (0,6) and (-3,-7). The slope of fourth line is


m_4=\frac{-7-6}{-3-0}=\frac{13}{3}

Since the slope of a vertical line is infinity, Therefore option A is correct.

Dimas [21]

Sara works 46 hours per week

9 hours are overtime and 37 hours are regular time

pay rate at time and a half: 10.20∗1.5=15.30

regular hours plus overtime pay

37∗10.20=377.40

9∗15.30=137.70

Income due to tips

Total hours worked∗60per hour∗20%

46∗60∗.20=552

Weekly Income=Hourly income + tips

Weekly Income=377.40+137.70+552.00

Annual income=Weekly income∗52

Annual income=55489.20

In a hydraulic lift, a 1400 N force is applied to a 0.5 m2 piston. Calculate the minimum surface area of the large piston to lif
dexar [7]

Answer:

1.8m^2 approx

Step-by-step explanation:

Given data

P1= 1400N

A1=0.5m^2

P2=5000 N

A2=??

Let us apply the formula to calculate the Area A2

P1/A1= P2/A2

substitute

1400/0.5= 5000/A2

cross multiply

1400*A2= 5000*0.5

1400*A2= 2500

A2= 2500/1400

A2= 1.78

Hence the Area is 1.8m^2 approx
