For this case, the first thing we must do is define variables.
We have then:
x: number of minutes
y: final temperature
We write then the equation that models the problem:
For y = 20 we have:
Clearing x:
Answer:
The temperature of the water will be 20 degree celcius after 150 minutes
Step-by-step explanation:
if the tank is filled with a cap on field to capacity how many half gallons of bottles are filled it will be about well first you have to think how much is half a gallon and it's a half of a gallon is 2 quarts how big is the tank that's what you want to know if you want to fill it up cuz I haven't gotten this 2 quarts tell me how big is the tank
Here, we can formulate the slope-intercept equation from the point and the slope:
Slope = -4/-4 = 1
x1 = -2
y1 = 5
By point-slope form:
(y-y1) = m (x - x1)
(y-5) = 1(x +2)
y-5 = x +2
Simplifying to slope-intercept form:
y = x + 7
Therefore, the slope-intercept form would be y = x+7
I hope my answer has come to your help. God bless and have a nice day ahead!
Answer:
y = 2 * 9 ^ x
Step-by-step explanation:
From the first point, you can get the value of a, since any number with power 0 with always equal to 1
Now you have y = (2)(b ^x), use the second point, substitute the value of X and y to (3,1458) to get the B value.
- 1458 = 2b ^ 3
- 729 = b ^ 3
- B = 9
