the answer is C a=3 for this equation
The second choice is not a relation.
The first and third choices have multiple (input, output) pairs that have the same input. Such a relation is not a function. Any time you see this, you know the relation is NOT a function.
The best answer is the 4th choice ...
... {(0, -9), (-9, 0), (-3, -3)}
Answer:
48.2°
Step-by-step explanation:
If a 15' ladder is leaned up against a building so that the bottom of the ladder is 10' from the base of the building, what angle does the ladder make with the ground
Let the angle the ladder makes with the ground be represented by x
We solve the above question using the Trigonometric function of Cosine
cos x = Adjacent/Hypotenuse
Adjacent = 10 inches
Hypotenuse = 15 inches
Hence,
cos x = 10/15
x = arc cos (10/15)
x = 48.189685104°
Approximately = 48.2°
Therefore, the angle the ladder makes with the ground is 48.2°
Answer:
The answer would be d, $15
Hope this helps!
Step-by-step explanation:
15 x 4/5=12
12+15=27
Answer:
(-6,3) and (-4,-5) are the solutions to the system
Step-by-step explanation:
The solution to a system of equations are the point(s) where the graphes intersect. On the graph is a linear function and an exponential. Because of the curve in the exponential, the graph has two solutions at (-6,3) and (-4,-5).
