How do I graph and find slope intercept for for x+y=0

1 answer:

4 0

Answer:

y = -x + <u>0</u>

slope intercept: 0

Step-by-step explanation:

You would start at the origin, since your slope intercept is 0. The slope, -1 (since -x is the same as -1x), is telling us the line will be negative, so the line you are graphing will be heading up one space at a time towards the left, up 1 and sideways 1. Rise over Run.

Find the slant height for a right circular cone with a radius of 3 and a height of 5.

babymother [125]

Answer: l = $\sqrt{34}$

Step-by-step explanation:

The slant height of a cone is given by

l = $\sqrt{h^{2}+r^{2} }$

h= 5

r = 3

Therefore :

l = $\sqrt{5^{2}+3^{2} }$

l= $\sqrt{25+9}$

l = $\sqrt{34}$

irakobra [83]

Answer:

The required interval is (26.23 , 27.37)

Step-by-step explanation:

The mean is = 26.8

The standard deviation is = 7.42

n = 654

At 95% confidence interval, the z score is 1.96

To find the desired interval we will calculate as:

$26.8+1.96(\frac{7.42}{\sqrt{654} } )$

And $26.8-1.96(\frac{7.42}{\sqrt{654} } )$

$26.8+0.57$ and $26.8-0.57$

= 27.37 and 26.23

So, the required interval is (26.23 , 27.37)
