Answer:
33
Step-by-step explanation:
2x^2 +3y
Let x =3 and y=5
2 *(3)^2 +3(5)
We do exponents first
2 * 9 + 3(5)
Then multiply
18+ 15
Add
33
Answer:
Equation 1 is the equation which represents the graph.
Step-by-step explanation:
The scale factor of two means you need to multiply the original length by 2:
9 x 2 = 18
The new length would be 18 cm.
Answer:
2 meters
Step-by-step explanation:
We need to use trigonometry for this. The appropriate one would be tangent, which is (opposite side) divided by (adjacent side).
In this case, the opposite side of angle A is BC, which is 6 meters. The adjacent side of angle A is AB, which is the ground. Since we don't know its length, we call it x.
Now, we write:
= 6/x
To solve, we just multiply both sides by tan(x) and x:
x = 6/[tan(72)] ≈ 1.95 meters ≈ 2 meters.
Thus, the answer is 2 meters.
