First, we work out the increase/decrease of the two amounts

There are 52-43 = 9 projects increase 

Percentage increase = \frac{number of increase}{original value}×100
Percentage increase = \frac{9}{43}×100
Percentage increase = 21% (to the nearest integer)

A square has a side length of 3x3y5. What is the area of the square?​
kotykmax [81]

Answer:

9x^3 y^5

Step-by-step explanation:

Since the formula to finding area is (L*W = A), we first have to find the width.

Width: 3x^3 y^5 times 2 = 6x^3 y^5

Then we add them. So, 3x^3 y^5 + 6x^3 y^5 = 9x^3 y^5

Which statement is true about the end behavior of the graphed function?
tatyana61 [14]

The <em><u>correct answer</u></em> is:

A) as the x-values go to positive infinity, the functions values go to negative infinity.  

Explanation:

We can see in the graph that the right hand portion continues downward to negative infinity.  The right hand side of the graph is "as x approaches positive infinity," since x continues to grow larger and larger.  This means as x approaches positive infinity, the value of the function approaches negative infinity.

What is the domain of the relation y = arccscx?
Stella [2.4K]

Answer:

y=arc\csc x

Step-by-step explanation:

The given function is y=arc\csc x.

The domain refers to all values of x for which this function is defined.

Recall that: the domain of y=arc \sin (x) is -1\le x\le1

And we know y=arc\csc x is the reciprocal of y=arc \sin (x).

Therefore the complement of the domain of y=arc \sin (x) which is (-\infty,-1]\cup [1,+\infty) is the domain of y=arc\csc x
