Which 1 is the equation 3x+9y=7 that passes through (6,4)

Mathematics

algol [13]3 years ago

Perpendicular lines have an negated inverse slope compared to a given line. so we need to find slope of line:
3x + 9y = 7
y = -1 / 3 x + 7

so the opposite of -1/3 is 1/3. flip the fraction to get the inverse and it is 3/1 or 3. 3 is then the slope of perpendicular line. now we see which one will work with it. there are 2 possible
3x+ 4 = y
3x - 14 = y

plug in the point on line and see if it works
3 (6) + 4 = 4 nope

3 (6) -14 = 4 yes
so 3x - 14 = y

What if the diameter of the inner sphere is 1.8 meters. What is the volume of the inflated space?
Alona [7]

Answer:

Volume is 3.05m³

Step-by-step explanation:

This problem bothers on the mensuration of solid shapes, sphere

Step one

The formula for the volume of a sphere is expressed as

V=4/3πr³

Step two

Given data

Diameter d = 1.8m

Radius r = d/2= 1.8/2= 0.9m

Step three

Substituting our given data we have

V= 4/3*3.142*0.9³

V= 4/3*3.142*0.729

V= 9.162/3

V=3.05m³
