Answer:800
Step-by-step explanation:
75% = 0.75
600/0.75 = x/1
Cross multiply:
0.75x = 600
Divide 0.75 to both sides:
x = 800
So the full does is 800mg.
15 bushes I think because if u divide them both by two u get the answers check it urself
Answer:
9.45
Step-by-step explanation:
none
Using the numbers in the given equation:
a =-2, b = 6 and c = -5
The vertex form is written as : a(x+d)^2 + e
we need to find d and e:
d = b/2a = 6/2(-2) = -3/2
e = c-b^2/4a = -5 - 6^2/4(-2) = -1/2
Now substitute the letters for their values in the vertex form formula above:
-2(x-3/2)^2 -1/2
The vertex is (3/2, -1/2)
2. The formula begins with a negative number ( -2) so the Parabola opens downwards.
3. To find the intercept replace x with 0 and solve for y:
the intercept is (0,-5)
