mr. rite wants his roof to be 90degrees at its peak and have a slope of -7/2 on the sunny side of the house. if the height of hi
1 answer:
Answer:
60 feet
Step-by-step explanation:
The slope of the roof is the vertical distance over the horizontal distance. This means for very 7 feet vertical the roof spreads out 2 feet horizontal. So if the roof is 210 feet vertical, then the horizontal will be _____.
This is found by setting up a proportionand solving for the unknown distance.
7y = 2*210
7y = 420
y = 60
The horizontal distance will be 60 feet.

domain represents the x values so for example in a diagonal line that continues infinitely, the domain is all real numbers or (-infinity, infinity)
range represents y values so it would also be all real numbers or (-infinity, infinity)
let’s say there is a line (refer to pic) that moves ONLY from point (-3, -1) and (2, 2)
the domain would be [-3, 2]
we use brackets because it’s a real number unlike infinity (also because it’s a closed circle on the graph; if the graph had an open circle you would use a parenthesis)
and the range would be [-1, 2]
