Determine whether the function f(x) = 3(x − 1)4 is even or odd. The function is even because f(x) = f(−x). The function is odd b

ecause f(x) = f(−x). The function is even because f(x) = −f(x). The function is odd because f(x) = −f(x).

Answer:

Step-by-step explanation:

given that

f(x)=3(x-1)^4

In order to determine whether a function is odd or even we are required to substitute x with -x and simplify

if f(-x) =f(x) it is an even function

if f(-x)=-f(x) it is an odd function

Hence

Let us put x=-x in our f(x)

f(-x)=3(-x-1)^4\\=3(-1(x+4))^4\\=3(x+1)^4

which is an entirely a  new function has no relation with the f(x) Hence it is neither an even function or an odd function.

I think some part of the question is missing here. Please recheck it once.

Korra is carrying a bag of books that weighs 40 pounds. After picking up some books at school, the weight has increased by
ch4aika [34]

Answer:

W' = 54.4  pounds

Step-by-step explanation:

Given that,

The weight of a bag of books = 40 pounds

After picking up some books at school, the weight has increased by  36%.

We need to find the weight of the bag now. Let the new weight is W'.

So,

W' = 40 +36% of 40

i.e.

W'=40+\dfrac{36}{100}\times 40\\W'=54.4\ pounds

So, the new weight of the bag is equal to 54.4  pounds.

Answer:

m∠CAB = 40°

Step-by-step explanation:

DAC = 99

DAB = 59

B is inside DAC, and so is DAB. So CAB must add to 59 to get to 99, nothing over that because it's inside DAC.

So 99 - 59 = 40

CAB must be 40°

That's all I can say for now. Hope this helps and a thank won't hurt! :)

lydia buys 5 pounds of apples and 3 pounds of bananas for a total of $8.50. ari buys 3 pounds of apples and 2 pounds of bananas
gavmur [86]

Answer:  The price per pound of apples is $ 1.25 and the price per pound of bananas is $ 0.75.

Step-by-step explanation:  Given that lydia buys 5 pounds of apples and 3 pounds of bananas for a total of $8.50 whereas Ari buys 3 pounds of apples and 2 pounds of bananas for a total of $5.25.

We are to find the price per pound of apples and bananas.

The cost per pound of apples is represented by x dollars and the cost per pound of bananas is represented by y dollars.

Then, according to the given information, the system of equations describing the situation is as follows:

5x+3y=8.50~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~(i)\\\\3x+2y=5.25~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~(ii)

Multiplying equation (i) by 2, we have

2(5x+3y)=2\times 8.50\\\\\Rightarrow 10x+6y=17~~~~~~~~~~~~~~~~~~~~~~~~(iii)

and multiplying equation (ii) by 3, we have

3(3x+2y)=3\times 5.25\\\\\Rightarrow 9x+6y=15.75~~~~~~~~~~~~~~~~~~~~~~~~(iv)

To eliminate y, we subtract equation (iv) from equation (iii) and we arrive at

(10x+6y)-(9x+6y)=17-15.75\\\\\Rightarrow x=1.25.

From equation (i), we get

5\times 1.25+3y=8.50\\\\\Rightarrow 6.25+3y=8.50\\\\\Rightarrow 3y=2.25\\\\\Rightarrow y=0.75.

Thus, the price per pound of apples is $ 1.25 and the price per pound of bananas is $ 0.75.

A kite has a perimeter of 70 centimeters. One of the shorter sides measures 16 centimeters. What are the lengths of the other th
Sveta_85 [38]
A kite has 2 short sides and 2 long sides. The 2 short sides are equal. The 2 long sides are also equal. This means that the other short side is 16cm. And the remaining longer sides can be found like this:
let's pretend *y* is the long side
2*y = 70 - 16 - 16. (two of the long sides = 70 - short side - another short side)
so use algebra to find y.
2*y = 38
y = 19 so the long sides are both 19cm each
Your final answer: 16cm, 19cm, 19cm
