1 is b and 2 is j and 3 is d
Q7.
The domain of the function y = sin x - 2 is x ≥ 2.
Answer: FALSE because is All Real Numbers
Q8.
The domain of the function y = cos x + 1 is All Real Numbers.
Answer: TRUE
Q9.
What's the domain of the function y = sin x?
Answer: All Real Numbers
Q10.
What is the range of the function y = sin x?
Answer: -1 ≤ y ≤ 1
Answer: <u>A</u>
Step-by-step explanation:
Domain is based off of the x-axis (left to right).
The curve starts at -1, and ends at 3. Therefore, x is greater than, or equal to -1, and x is less than, or equal to 3.
Also note that the dots signifying the beginning and end of the line is filled in (completely black). If the dot was not filled in, that's basically saying that line <em>doesn't</em> include the number the dot is on.
The equation is:
I=100+12J+5T+7S+5H-8M
The given information is that I=197, J=5, T=5, H=3, and M=3, and we’re trying to solve for the amount of shorts (S) he sold.
We can plug in the variables into the equation:
(197)=100+12(5)+5(5)+7S+5(3)-8(3)
After simplification:
197=100+60+25+7S+15-24
We can add/subtract the constants:
197=100+60+25+7S+15-24
We will add/subtract the constants:
197=176+7S
We will subtract 176 from both sides of the equation to cancel it out and isolate 7S:
197-176=176-176+7S
21=7S
We will divide 7 from both sides of the equation to cancel it out and isolate S:
21/7=7S/7
3=S or S=3 with the symmetric property of Equality applied.
Therefore, he sold 3 pairs of shorts
Answer:
b=3.1cm
Step-by-step explanation:
2a+b=15.7
a=6.3
2*6.3+b=15.7
12.6+b=15.7
b=3.1cm
