The two plans don't fall directly on a same prive, but after 3 hours of Data usage plan B costs more than plan A
After three hours plan A= $18.60
While plan B after three hours =$19.09
That means 3 hours has to pass before plan B costs more, That is 180 minutes
The rule per hour is $1.2 per hour for plan A and $4.8 per hour for plan B
Answer: (A) If the number of cups of cereal is 40, then the number of cups of raisins will be 10.
Step-by-step explanation:
From the given table , we can check the given quantities are in proportion .
Since ,
So this case is of direct proportion, where the number of cereal cups is 4 times the cups of raisins.
It is said that A point is plotted on the ordered pair 40,20.
But
Hence, Molly is incorrect.
Since ,
Because, if the number of cereals is 40, then the number of raisins should be 10 such that,
D = rt
D = 50(4)
D = 200 miles
From a coordinate point of view, we have a function D(x) = 50x, where x represents time in hours.
When x = 4, y = 200.
(x, y) = (domain, range).
Our domain is 4 hours and range 200 miles.
Answer:
.
Step-by-step explanation:
Given : = 128.
To find : what is the logarithmic form of the equation in base 10
Solution : We have given that = 128.
By th change base rule ( inverse of exponential function )
= c is equal to = b
Then = 128 in to logarithm form = x.
Then in to the base 10 logarithmic form.
By the change of base formula .
Then , .
Therefore, .
The equation for a circle is (x-h)^2+(y-k)^2 = r^2
The h part in with the x is your x coordinate and the k part in with the y is your y coordinate. The r stands for the radius but be careful you have to square it.
so:
(x-(4))^2 +(y-(6)^2 = 16
I like to add the parenthesis around the "plugged in" numbers to help me remember negatives if I have any. <span />
