Answer:
22.8 grams
Step-by-step explanation:
To find total amount of medicine, we have to add all the 3 quantities of Chemical A, Chemical B, and Chemical C.
Before we do that, we have to round up each quantity to the nearest tenths.
Nearest tenths means we can take "1 digit" after the decimal point. For that we use rounding rules.
If the 2nd digit to the right of decimal is 5 or greater, we round up the 1st digit to the next whole number. If the 2nd digit is less than 5, we keep the 1st digit same.
So, using that we round up each of the three numbers as shown:
3.732 becomes 3.7 (since 3 is less than 5, we keep the 7)
13.902 becomes 13.9 (since 0 is less than 5, we keep 9)
5.208 becomes 5.2 (since 0 is less than 5, we keep 2)
Now we add:
3.7 + 13.9 + 5.2 = 22.8 grams
Answer:
t is less than or equal to 4
Step-by-step explanation:
Answer:
The sine and cosine functions have a period of 2π radians and the tangent function has a period of π radians. Domain and range: From the graphs above we see that for both the sine and cosine functions the domain is all real numbers and the range is all reals from −1 to +1 inclusive.

Answer:
2 inches
Step-by-step explanation:
36 divided by 6= 6
So 12 divided by 6 is 2
Answer:
i) Equation can have exactly 2 zeroes.
ii) Both the zeroes will be real and distinctive.
Step-by-step explanation:
is the given equation.
It is of the form of quadratic equation 
and highest degree of the polynomial is 2.
Now, FUNDAMENTAL THEOREM OF ALGEBRA
If P(x) is a polynomial of degree n ≥ 1, then P(x) = 0 has exactly n roots, including multiple and complex roots.
So, the equation can have exact 2 zeroes (roots).
Also, find discriminant D = 
⇒ D = 37
Here, since D > 0, So both the roots will be real and distinctive.
