Answer:
y = -2(x + 1)^2 + 8
Step-by-step explanation:
The equation of a parabola can be written in the form;
y = a(x-h)^2 + k
where a is the multiplier (h,k) is the vertex
so h = -1 and k = 8
Plug in these values
y = a(x + 1)^2 + 8
So to get the value of a, we use the point where the parabola passes through which is the point (1,0)
Simply substitute the values of x and y
0 = a(1 + 1)^2 + 8
0 = a(2)^2 + 8
-8 = 4a
a = -8/4
a = -2
So therefore the equation of the parabola is ;
y = -2(x + 1)^2 + 8
Answer:
14 to 25
Step-by-step explanation:
there are 14 women and 24 people altogether
3n=27+3
you can do anything as long as you do it to both sides
3n=27+3
add like terms
27+3=30
3n=30
divide both sides by 3
n=10
Look at the picture.
We have 3 cuboids. The formula of a volume of a cuboid is:
V = Length × Width × Height = lwh
The cuboid 1 are congruent to the cuboid 2.
<h2>1&2</h2>
l = 9 in, w = 10 in, h = 10 in
V = (9)(10)(10) = 900 in³
<h2>3</h2>
l = 6 in, w = 10 in, h = 10 in
V = (6)(10)(10) = 600 in³
The volume of the composite prism:
V = 2(900) + 600 = 1800 + 600 = 2400 in³
