ANSWER:
3/8 longer or 2 times longer or 22.5 minutes longer on Monday depending on the type of answer they want.

EXPLANATION:
3/8 longer or 2 times longer Explanation is:
Gotta find common denominator
Common denominator is 8
6/8 on Monday and 3/8 on Tuesday so difference of 3/8 or twice as long

22.5 Minutes Longer explanation is:
3/4 of an hour is 45 minutes (60/4=15x3=45) 3/8 of an hour is 7.5 minutes (60/8=7.5x3=22.5)
So 45-22.5= 22.5 minutes longer on Monday

Which statement best describes how to determine whether f(x) = 9- 4x4 is an odd function?
vitfil [10]

Answer:

Option C.

Step-by-step explanation:

Note: In the given function the power of x should be 2 instead of 4, otherwise all options are incorrect.

Consider the given function is

f(x)=9-4x^2

If f(-x)=f(x), then f(x) is an even function.

If f(-x)=-f(x), then f(x) is an odd function.

Now, substitute x=-x in the given function.

f(-x)=9-4(-x)^2

f(-x)=9-4(x)^2

f(-x)=f(x)

So, the given function not an odd function. It means it is an even function.

To check whether the given function is odd, we have to determine whether 9-4(-x)^2 is equivalent to -(9-4(x)^2).

Therefore, the correct option is C.

Last Tuesday was silly hat day at Toby's school. 74 students wore a silly hat and 666 students did not. What percentage of the s
valina [46]

Answer:

10%

Step-by-step explanation:

The total population of students will be equal to the sum of both those who wore the silly hat and those who didn't hence

Total students= 74+666=740

Number of students who wore silly hat is given as 74 hence when expressed as a percentage of the total students' population we get that

percentage of the students wore a silly hat=\frac {74\times 100}{740}=10\%

Therefore, 10% of students wore a silly hat last Tuesday

For this case we have the following functions:
 f (x) = 3x + 4
 g (x) = 2 ^ x - 1
 The intersection with the y axis of the original functions is:
 f (0) = 3 (0) + 4 = 0 + 4 = 4
 g (0) = 2 ^ 0 - 1 = 1 - 1 = 0
 The transformations that must be applied so that they have the same intersection with the y axis are:
 f (x) - 3
 g (x) + 1
 Answer:
 
f (x) - 3
 
g (x) + 1
 
option 1
