Answer:
x = 10935/59048 = 0.185
Step-by-step explanation:
27 = 3^3
(27)^2 = (33)^2 = 36
Answer:
Factored form is 4x(2x+3)
Step-by-step explanation:
The factors are
8x^2 ----> 2*2*2*x*x
12x -------> 2*2*3*x
GCF is 2 * 2 * x= 4x
Now we factor out GCF from 8x^2 + 12x
When we factor out GCF, divide each term by 4x
4x(2x +3)
Factored form is 4x(2x+3)
Answer:
y = -5x - 19
Step-by-step explanation:
Find the y intercept using slope intercept form [ y = mx + b ]
y = -5x + b
-4 = -5(-3) + b
-4 = 15 + b
-19 = b
y = -5x - 19
Best of Luck!
This question is the application of differential eqns in order to derive a model for the temperature dependence with time. Actually, a general equation has already been derived for this type of cases. This equation is known as the Newton's Law of Cooling. The equation is
(T - Ts) / (To -Ts) = e^(-kt)
where T is the the temperature at any time t
Ts is the surrounding temperature
To is the initial temperature
k is the constant
t is the time
several assumptions have been made to arrive at this form, i suggest you trace the derivation of the general formula.
First we need to look for k using the initial conditions that is @t = 1.5 min, T = 50 F
substituting we get a k = 0.2703
therefore @ t = 1 min, T = 55.79 F
@ T = 15 F the time required is 9.193 min.
Numbers that are 510 to 540 (with zeroes) I'm not too sure about the ones place but also numbers 1-4. For example, 521, 1 rounded to 20 = 20. 20 rounded to 500 = 500. You get me?
