A vertical line contains the points 3,2 and 3,6 use these points and the formula for slope to explain why a vertical lines slope

is undefined
Mathematics
1 answer:
Dahasolnce [82]2 years ago
4 0

Answer:

see explanation

Step-by-step explanation:

Calculate the slope m using the slope formula

m = (y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = (3, 2) and (x₂, y₂ ) = (3, 6)

m = \frac{6-2}{3-3} = \frac{4}{0}

Since division by zero is undefined then the slope of the vertical line is undefined.

Sal pitched 15 games. If Sal pitched 3 out of 5 games his team played, how many games did his team play?
fiasKO [112]

Answer:

As we know he pinched 15 games and he pitched 3/5, we can do a rule of three:

15 - 3/5

x 1

We out a 1 ad that's the total, 5//5

So now we know x = , = 25

He pitched 25 games

Find the zeros, vertical asymptote, horizontal asymptote, slant asymptote, and graphing points.
kramer
Zeroes
set numerator to zero
x^2=0
x=0
zeroes are at (0,0)

HA

for p(x)/q(x)

when degree of p(x)<q(x), HA=0

when degree of p(x)=q(x), HA= leading coef of p(x) divided by leading coef of q(x)

when degree of p(x)>q(x) you probably have a slant assymtote

degrees are same (no slant assymtote)

leading coefs

1/1=1

HA is y=1

does it cross?

1=(x^2)/(x^2-4)

x^2-4=x^2

minus x^2 both sides

-4=0

false, it does not cross the HA



VA

simplify the fraction (it can't)

set the denomenator to zero

(x-2)(x+2)=0

VA's at x=2 and x=-2




so to graph

graph the point (0,0)

draw the lines

y=1

x=-2

x=2

reemmber, plus, minus, plus

so from left, it goes from above the HA right up to the VA of x=-2

then goes upside down U shape in between VA's going through (0,0)

then from top of VA x=2 down to y=1 then gets closer to y=1 but never touches

A polling organization announces that the proportion of American voters who favor congressional term limits is 64%, with a 95% c
EastWind [94]

Answer:

Hence when C.I. is 80% then Margin of error will be 1.9591%

Step-by-step explanation:

Given:

1st Margin of error(MOE)=3%

1st C.I.=95%

2nd C.I.=80%

To Find:

MOE at 80%

Solution:

The proportion is 64 % i.e. is constant for both MOE

Proportion is given by (P),

P=x/n

Where x= favors congressional terms

n= total voters or sampled voters.

There values are same or constant.

i.e standard deviation is also constant

Now Formula for MOE is given by

MOE=Z*[Standard devation/Sqrt(n)]

here Z is value for confidence interval

MOE is directly proportional to the Z-value

So

MOE=K*Z-value         ... where k is proportionality constant.

MOE/Z-value              ....ratio is constant

So , for 95 % Z=1.96 and for 80% Z=1.28

MOE(1st)/(Z-value 1st)=MOE(2nd)/(Z-value 2nd)

3/1.96=MOE(2nd)/1.28

MOE(2nd)=(3/1.96)*1.28

MOE(2nd)=1.5306*1.28

=1.9591 %

12 The drawing plan for an art studio shows a rectangle that is 19.2 inches by 6 inches. The scale in the plan is 3 In.: 5 ft. F
Vilka [71]
The length is 32 feet, the width is 10 feet, and the area is 320 feet squared.
EXPLAIN
19.2 divided by 3 is 6.4.
6.4•5=32.
6 divided by 3 is 2.
2•5=10
The room is 32 ft by 10 ft
32•10=320 ft
The area is 320 ft squared
