Answer:
x = - 2
Step-by-step explanation:
The equation of a vertical line parallel to the y- axis is
x = c
Where c is the value of the x- coordinates the line passes through.
The line passes through (- 2, - 3) and (- 2, 2)
Both of these points have an x- coordinate of - 2, thus
x = - 2 ← equation of line
Answer:
x = √(3^125/ 5)
approx 2.9552445 * 10^29.
Step-by-step explanation:
2 log3 x + log3 5 =125
log3 x^2 + log3 5 = 125
log3 (5x^2) = 125
3^125 = 5x^2
x^2 = 3^125/ 5
x = √(3^125/ 5)
This is a huge number
An approximation of it is 2.9552445 * 10^29.
18 - 5z + 6z > 3 + 6
18 + z > 9
-18 -18
z > -9
Answer:
A. T=7.12°C; B. t=3.32min
Step-by-step explanation:
In order to find the answer we can use the Newton's law of cooling:
where:
y0=initial temperature - room temperature
k=coefficients
t=time
Because the outdoors temperature is 3°C, the initial temperature is 20°C, and because the thermometer reads 11°C after 1min we have:



A. Temperature after an extra minute.

so the answer is 7.12°C
B. Time in order to read 4°C
