Answer:
B
Step-by-step explanation:
using the tangent ratio on the triangle on the right and the exact value
tan60° = , then letting the altitude be h
tan60° = =
=
( multiply both sides by h )
11 = h ×
( divide both sides by
)
11 = h
using the sine ratio in the triangle on the left and the exact value
sin45° = , then
sin45° = =
=
=
( cross- multiply )
× x = 22
( divide both sides by
)
x = 22
Answer:
1) These linear functions must not describe a pair of parallel lines.
2) Any intersection of two lines determines a point.
Step-by-step explanation:
Hi there!
Well, since no further details were given. Let's call the linear function that represents the number of animals adopted from the shelter . And
the hours the volunteers work at the shelter each week
1) These linear functions must not describe a pair of parallel lines.
If these lines intersect, then their slope must be different.
Equal slopes, parallel lines. Parallel lines, no intersection.
Different slopes, then there is an intersection at some point.
2) Any intersection of two lines determines a point. Let's find it.
So to find one common point equalize the two functions, then find the value for the x-coordinate. Plug it in one of the functions, e.g.
At the common point, both functions after inserted the same value in the Domain (x) return the same result for their respective Range set.
