Dennis stood on a 9 foot ladder to measure the sunflower. How much taller is the tallest sunflower than the ladder?
Shalnov [3]

Answer:

See Explanation

Step-by-step explanation:

Given

Ladder = 9ft

Tallest\ Sunflower = x

Required

How much taller is the tallest

To get this, we simply calculate the difference between the height of the tallest sunflower and the ladder.

i.e.

Difference  = Tallest\ Sunflower - Ladder

Difference  = x - 9

-----------------------------------------------------------------------------------------------------

If for instance, the tallest is 13ft, then it is 4ft taller.

Because:

Difference = 13ft - 9ft

Difference = 4ft

Choose the BEST estimate!
Novay_Z [31]

Answer:

About 300 dollars

Step-by-step explanation:

THe best estimate for week one is 300, because 96 rounds to 100, and 100 * 3 equals 300.

The best estimate for week 2 is 600, because 204 rounds to 200, and 200 * 3 equals 600.

600 - 300 = 300, therefore the difference is about 300 dollars.

Hope this helps!

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.

Six more than five times a number is at least twenty-one
kakasveta [241]
Lets say the number is x so we can make an equation
If is at least 21, that means it has to be greater then or equal to it.
6+5*x>=21
You can subtract 6 from both sides
5*x>=15
Then divide both sides by 5
x>=3
You can conclude that the number is greater then or equal to 3.
