Given equation, y = – 1.3(x + 3)2 – 9 is in slope intercept form.
Step-by-step explanation:
Slope intercept form standard formula:
y = mx + c
where,
y= y intercept
x= x intercept
m = slope
c = constant
We are given:
y = - 1.3(x + 3)2 - 9
y = - 2.6x + 7.8 - 9
y = -2.6x -1.2
So,
Slope = m = -2.6
constant = 1.2
Yes you do. Place all of the numbers, even repeating ones, in order from slammers to largest and then start crossing out from both sides until you get the middle. For example, in the problem below the median would be 4 bc it’s in the middle
1,2,2,3,4,6,6,7,8
To make the reciprocal of a fraction, swap the numerator and denominator.
The reciprocal of 3/4 is 4/3.

To make the reciprocal of an integer, write it as a fraction, then proceed as above. Example: (reciprocal of 2) = (reciprocal of 2/1) is 1/2.
Not surprisingly, the reciprocal of a number x is written 1/x.
0.3x ≥ 0.6
Divide both sides by 0.3,
0.3x / 0.3 ≥ 0.6/0.3
x ≥ 2
So, your final answer is x ≥ 2
Hope this helps!
Answer:
15 centimeters.
Step-by-step explanation:
We must calculate the volume of each cylinder and add it, like this:
v = pi * (r ^ 2) * l
replacing:
v1 = 3.14 * (5 ^ 2) * 7
v1 = 549.5
v2 = 3.14 * (10 ^ 2) * 5
v2 = 1570
The sum would be:
549.5 + 1570 = 2119.5
That would be the volume of the cylindrical disk, this case would be the same formula only that it would not be length but thickness, like this:
v = pi * (r ^ 2) * t
we want to know r, therefore:
r ^ 2 = v / pi * t
replacing:
r ^ 2 = 2119.5 / (3.14 * 3)
r ^ 2 = 225
r = 15
which means that the radius would be 15 centimeters.
