Answer:
Step-by-step explanation:
To find the x intercepts, substitute in 0 for y and solve for x
So,
2x^2+2x-4 = 0
2(x^2+x-4) = 0
2/2(x^2+x-4) = 0/2
x^2+x-4 = 0
(x-1) (x+2) = 0
now,
x-1 = 0
x = 1
or
x+2 = 0
x = -2
The x intercepts for the parabola (1,0), (-2,0)
5/9 + 1/3 = 5/9 + 3/9 = 8/9 <==
Answer:
Step-by-step explanation:
Here, we want to get the value of angle DEF
we have this as ;
Angle DEF = 1/2 * DOF
1/2 * 150 = 75
This is because angle at the center is twice the angle at the circumference
Answer:9898
Step-by-step explanation:
bc 9+8=0-9
Step-by-step explanation:
a)
dy/dx = 4x √(1 − y²)
Separate the variables:
dy / √(1 − y²) = 4x dx
Integrate:
sin⁻¹ y = 2x² + C
Solve for y:
y = sin(2x² + C)
b)
Plug in initial value.
4 = sin(0 + C)
Sine cannot be greater than 1, so there is no solution.
