Answer:
1/4
Step-by-step explanation:
Answer:
8.058655822 mins
Step-by-step explanation:
We have a table and to solve for this we might want to find the equation for this
This is a exponential function
To solve for this we need the rate of decay and the x intercept
We know the x intercept is 180 because in 0 mins the temp is 180
To solve for decay we need to know the temp of the cake after 1 min
to get the decay value we can do
125= 180 (x)^5
.69444444444 = x^5
0.929667185 = x
so the equation would be
180 (0.929667185)^x
if we tell this equation to equal 100
we get
100 = 180 (0.929667185)^x
.5556 = (0.929667185)^x
log .5556 = log 0.929667185 *x
log .5556 / log .929667185)
8.058655822= x
After 8.058655822 mins the cake will be 100 degrees
Answer:
3x and 8x
Step-by-step explanation:
They both share the same variable unlike 8 and 3y which have different variables. Once simplified, the expression should equal 11x + 8 + 3y
Answer:
-5, 4.1, 4.7, 16 squared
Step-by-step explanation:
negative numbers are always the least, then 4.1 is less than 47/10 which is 4.7 and 16 squared which is 256, then we have 4.7 because that is less than 256 which is the greatest number.
Answer:
x=3y
Step-by-step explanation:
ATQ
(x+y):(x-y)=2
or, x+y=2x-2y (crossmultiply)
or, 0= 2x-x-2y-y
or, x- 3y=0
or, x=3y is required equation
