Answer:
y = 2x^2 + 4x - 2
Step-by-step explanation:
y=2(x+1)^(2)-4 is in vertex form. We want the same equation in standard form, which looks like y = ax^2 + bx + c.
Perform the indicated multiplication (squaring of x + 1):
y = 2(x^2 + 2x + 1) - 4, or
y = 2x^2 + 4x + 2 - 4, or
y = 2x^2 + 4x - 2 This is in the standard form of a quadatic.
9 feet
Use Pythagorean theorem:
Leg: 12
Hypotenuse: 15
12^2 + x^2 = 15^2
144 + x^2 = 225
x^2 = 81
x = 9
Answer:
1. 2×1/6=1/3
2. 4×3/8=1 1/2
3. 1/4x3=3/4
4. 2/5x 5= 2
Step-by-step explanation:
Answer:
At 50 km/hr, she travels a distance of 40 km
At 100 km/hr, she travels a distance of 160 km
Step-by-step explanation:
The general formula for distance = d = r*t
distance / rate = time
x/50 + y / 100 = 2.4 Multiply by 100
2x + y = 240
x + y = 200
Subtract the two equations
x = 40 km
y = 200 - 40
y = 160 km
