Determine the domain on which the following function is decreasing.

Mathematics
1 answer:
dexar [7]3 years ago
7 0
The way I remember domain(the distance where x is shown) and range(the distance where y is shown) is that it lines up with an ordered pair. It sounds wrong to say range and domain, just like it sounds wrong to say y,x.

the answer for this would be [0,11]

a teacher asked 3 pupils to choose any 2 digit number square it and then find the remainder after dividing the result by 7. Dori
gizmo_the_mogwai [7]
First write out all the two digit square numbers

4² = 16
5² = 25
6² = 36
7² = 49
8² = 64
9² = 81

Next divide all of them by 7

16/7 = 2 2/7 or 2 and 2 remainders
25/7 = 3 4/7 or 3 and 4 remainders
36/7 = 5 1/7 or 5 and 1 remainder 
49/7 = 7
64/7 = 9 1/7 or 9 and 1 remainder
81/7 = 11 4/7 or 11 and 4 remainders

This tells us that the only possible remainders for a two digit square number divided by 7 are 1, 2 and 4
If Doris got 6 and Horace got 3, they must have made a mistake.

A truck rental is $25 plus $ 0.40/mi find out how many miles ken traveled if his bill is $59.40
Zanzabum

Answer:

Step-by-step explanation:

C = 59.4

Fixed Cost (F) = 25

C = 25 + 0.4*x                    Solve for x

59.40 = 25 + 0.4x              Subtract 25

34.4  = 0.4x                        Divide by .4

34.4/0.4 = x

x = 86 miles

Use the Binomial Theorem to expand the binomial.
Artist 52 [7]
<h3><u>d^3 - 4bd^2 + 16b^2d - 64d^3 is the expanded binomial.</u></h3>

The binomial theorem involves Pascal's triangle, and essentially gives you the coefficients for the formula you're going to use to expand it.

In this case, the coefficients will be 1, 3, 3, and 1.


We can set up our formula like this:

(a + (-b)) = a^3 + a^2b + ab^2 + b^3

Now we can just plug in our values:

(d + (-4b))^3 = d^3 + d^2(-4b) + d(-4b)^2 + (-4b)^3

Now, we can simplify the equation.

(d + (-4b))^3 = d^3 - 4bd^2 + 16b^2d - 64d^3
