Answer:
Which is the output of the formula =AND(12>6;6>3;3>9)?
A.
TRUE
B.
FALSE
C.
12
D.
9
Step-by-step explanation:
Answer: B is reasonable
Step-by-step explanation: In 4 hours, you hike 10 miles. Divide 10 miles by 4 hours to get miles per hour, which is what you want to solve for in this problem. 10 divided by 4 is 2.5, which means you can hike 1 mile in 2.5 hours.
Answer:
option (a) f(x)= 1/x+2
Step-by-step explanation:
(a) f(x) = 1/ x+2
To find the restriction for domain , we set the denominator =0 and solve for x
x+2 =0, so x=-2
When x=-2 then denominator becomes 0 that is undefined.
So, domain is all real numbers except -2
(b) f(x)= 2x
In this function, there is no denominator or square root or log function
so there is no restriction for x, hence domain is all real numbers
(c) f(x) = 2x-2
In this function, there is no denominator or square root or log function
so there is no restriction for x, hence domain is all real numbers
f(x) = 1/ sqrt(x+2)
if we have square root in the denominator then we set the denominator >0 and solve for x. because square root of negative values are undefined
x+2>0, x>-2
Hence domain is all real numbers that are greater than -2

<h3><u>Question:</u></h3>
Ricky rides his bike 12 miles every day. He stops after 7 miles to rest. write and solve an equation to find out how much further he has to ride
<h3><u>Answer:</u></h3>
Ricky has to further ride for 5 miles
<h3><u>Solution:</u></h3>
Given that, Ricky rides his bike 12 miles every day
Let "x" be the remaining distance in miles he has to ride further
Total distance = 12 miles
Also, given that he stops after 7 miles to rest
Therefore, already covered distance = 7 miles
Therefore, we can frame a equation as,
remaining distance + already covered distance = total distance
x + 7 = 12
Solve the above equation for "x"
x = 12 - 7
x = 5
Thus Ricky has to further ride for 5 miles
