Is it possible with only letters
1.898 kilograms... as you just have to divide
Answer:
Let's define the high temperature as T.
We know that:
"four times T, was more than 2*T plus 66°C"
(i assume that the temperature is in °C)
We can write this inequality as:
4*T > 2*T + 66°C
Now we just need to solve this for T.
subtracting 2*T in both sides, we get:
4*T - 2*T > 2*T + 66°C - 2*T
2*T > 66°C
Now we can divide both sides by 2:
2*T/2 > 66°C/2
T > 33°C
So T was larger than 33°C
Notice that T = 33°C is not a solution of the inequality, then we should use the symbol ( for the set notation.
Then the range of possible temperatures is:
(33°C, ...)
Where we do not have an upper limit, so we could write this as:
(33°C, ∞°C)
(ignoring the fact that ∞°C is something impossible because it means infinite energy, but for the given problem it works)
Y = (2x-12)/3
We have to find where the x intercept is.
(2x-12)/3 = 0
2x=12
X = 6
When x = 0, y = -4
We have to take the integral from 0->6
pi * integral(0->6) (((2x-12)/3)^2)dx
pi * integral(0->6) ((4x^2 - 48x + 144)/9)dx
4pi/9 * integral(0->6)(x^2 - 12x + 36)dx
4pi/9 * (x^3/3 - 6x^2 + 36x) [0->6]
4pi/9 (6^3/3 - 6(36) + 36(6))
4pi/9 (72)
4pi(8)
32pi = 100.53 units ^3, or B
<h3>I'll teach you how to solve 15x ^2 −4x−4</h3>
--------------------------------------------------------
15x ^2 −4x−4
Break the expressions into groups:
(15x^2+6x) + (-10x-4)
Factor out 3x from 15x^2+6x:
3x(5x+2)
Factor out -2 from -10x-4:
-2(5x+2)
3x(5x+2) -2(5x+2)
Factor out common term 5x+2:
(5x+2)(3x-2)
Your Answer Is (5x+2)(3x-2)
