The population of a certain country is approximated by the following equation, where x is the number of years since 1980 and P i
saveliy_v [14]

Answer:

235

Step-by-step explanation:

The population equation is given as P= 2.726x + 126.189

-To find the number of years since 1980, we subtract the start year from the current year(2020):

X=2020-1980=40

We substitute the x value in the population equation to find the current population:

P=2.76x+126.189 but x=40

P=2.76(40)+126.189=235.229

Rounding off then the population in the current year is 235

Which of the following is a result of shifting a circle with equation (x + 3)2 + (y - 2)2 = 36 up 3 units? A. The x-coordinate o
Katen [24]

Answer:

D. (y-2) becomes (y-5) and -5 < -2

Step-by-step explanation:

When transforming functions, the following applies:

• Adding/subtracting inside the parenthesis to the input shifts the function left(+) and right(-).

• Adding/subtracting outside the parenthesis to the output shifts the function up(+) and down(-).

• Multiplying the function by a number less than 1 compresses it towards the x-axis.

• Multiplying the function by a number greater than 1 stretches it away from the x-axis.

In this situation, the circle is shifted up 3 units and the variable y which controls this is in the function. To move it up you will subtract 3 in the parenthesis for (y-2) so it becomes (y-5). This will move the vertex 3 units higher.

Multiply y^2-16/2y . 5y/y-4
alisha [4.7K]
So, first we multiply the fraction by using the formula a/b times c/d= a times c/b times d
=(y^2-16) times 5y/2y(y-4)
Now, we cancel the common factor y
=(y^2-16) times 5/2(y-4)
Now, we factor 5(y^2-16)
We factor (y^2-16) first
y^2-16
Rewrite 16 as 4^2
y^2-4^2
Now, apply the formula x^2-y^2=(x+y)(x-y)
=y^2-4^2=(y+4)(y-4)
=5(y+4)(y-4)
=5(y+4)(y-4)/2(y-4)
Cancel the common factor y-4
=5(y+4)/2
Answer: 5(y+4)/2
