Answer:
32 minutes
Step-by-step explanation:
all you have to do is know that the unit rate is 4 so multiply 8 and 4 to get 32
You simply do 6x5x4x3x2x1 :)
<h2>
Thus, the required "option 4)" is correct.</h2>
Step-by-step explanation:
We find,
To find, the binomial expansion of of = ?
We know that,
∴
Here, n = 7, x = x and y = 2y
= 
∴ The binomial expansion of of
Thus, the required "option 4)" is correct.
1. first parabola is up, so a are going to be positive
y = a(x-r)(x-s),
roots -7,-3, so we can write y=a(x+7)(x+3) [1]
we can take point (-5,-2), substitute into equation [1], and find value of a
-2=a(-5+7)(-5+3)
-2=a*2*(-2)
a=1/2
so first parabola has an equation
y=1/2(x+7)(x+3)
2. second parabola
y=a(x-r)(x-s) roots are 2 and 4 so we ca write
y=a(x-2)(x-4) take point (3,4) and substitute into this equation
4 =a(3-2)(3-4)
4=-a
a=-4, and it will look down
y=-4(x-2)(x-4)
