It's going to be 35 present
Answer:
Domain: (−∞,∞), {x | x ∈ R}
Range: [3,∞), {y | y ≥ 3}
Graph the equation to find the domain and range.
Answer:
70.5°
Step-by-step explanation:
To solve for the ladder's angle of elevation, we solve using the Trigonometric function of Cosine
= cos θ = Adjacent/Hypotenuse
Where
Adjacent = Distance of the base from the house = 10ft
Hypotenuse = Length of the ladder = 30 ft
cos θ = 10/30
cos θ = 1/3
θ = arc cos 1/3
θ = 70.528779366
Approximately = 70.5°
Therefore, the ladder's angle of elevation is 70.5°
The answer is D.) (4,-1) Because all you need to do is put in the numbers into the equation to make sure it equals 16
