Answer:
Step-by-step explanation:
The last answer choice is the correct one. The common ratio here is 0.7, which is between 0 and 1, an important criterion for recognizing an exponential decal function. Every time x increases, f(x) will decrease.
Step-by-step explanation:
domain is from -3 to 4 [-3,4]
range is from 0 to 5 [0,5]
it is a relation because 4 has one to many relationship
Answer:An obtuse angle is any angle larger than 90 degrees
Step-by-step explanation:
Answer:
a) (6,4)
b) (5, 4.5)
Step-by-step explanation:
much like when you find them midpoint where you average the x-coordinates and the y-coordinates to find the midpoint coordinates, you'll do the same thing here.
to set context, a midpoint would break the segment into a ratio of 1:1.
so in the first part, a ratio of 1:2 means you are breaking the segment into 3-parts. So you'll do this for the coordinates:
for the second part as the ratio is 1:3, you are breaking the segment into 4 parts.
15>7-t\3(multiply both sides by 3 to remove the denominator)
45>7-t(then collect the like terms)
45-7>-t
38>-t(divide both sides by negative;note that when you divide by a negative the sign changes from>to<
-38<t
