Answer:
3/5y
Step-by-step explanation:
6y/35 ÷10y^2/7
to solve this you do reciprocal of 10y^2/7
then;
6y/35 x 7/10y^2
solving this
3/5y
Answer:
Step-by-step explanation:
Given is a function as ![x^5-3x+1](https://tex.z-dn.net/?f=x%5E5-3x%2B1)
Equating to 0 we have equation
If the function f(x) has x intercepts then the solutions are real
Let us use remainder theorem and change of signs rule
f(0) = 1>0
f(-1) = -1+3+1=3
f(-2) = -32+6+1<0
This implies there is a real root between -1 and -2.
f(1) = -1
Since f(0) and f(1) have different signs, there exists a real root between 0 and 1.
f(2) = 32-6+1>0
Since f(1) and f(2) have different signs there exists a real root between 1 and 2.
Thus there are definitely three real solutions as
one between -1 and 0, one between 0 and 1, and third between 1 and 2.
The <u>correct answer</u> is:
0.08.
Explanation:
To calculate the BAC, we first find the amount of alcohol (in grams) of the drinks. In the US, a standard drink has 14 g of alcohol. The man has 2 beers and 1 shot; this is 3 standard drinks:
3*14 = 42
This has 42 g of alcohol.
Next we convert the weight in pounds to grams. We do this by multiplying by 454:
140*454 = 63560
Next we multiply by the gender constant. For men, this is 0.68:
63560(0.68) = 43220.8
We divide the grams of alcohol by this number:
42/43220.8 = 0.000972
Multiply this by 100:
0.000972(100) = 0.0972
This is the BAC right after drinking. To account for the time that has passed, we multiply the number of hours by 0.015:
1(0.015) = 0.015
We subtract this from our immediate BAC:
0.0972-0.015 = 0.0822 ≈ 0.08
