8 0

Answer:

sinx

Step-by-step explanation:

hello :

note :

for all x in ℝ :   1) sin(x+2π) = sinx        2)  sin(π-x) = sinx

in this exercice :

3π - x = 2π+(π - x)

sin(3π - x) = sin(2π +(π - x)) =sin(π-x) = sinx

The integer change is -450 cm^3

Step-by-step explanation:

Here, we want to write the integer of the change in the volume of a ballon when it loses 450 cm^3 of air

Losing this volume means we are subtracting 450 from the original volume

This represents a change of -450 cm^3

What is the value of x?<br> (2x + 2)<br> (3x - 527<br> Enter your answer in the box.<br> Next
telo118 [61]

Answer:

The roots (zeroes) are -1 and 527 over 3.

Step-by-step explanation:

First, you gotta do the FOIL method and multiply the values which gives u 6x^(2) -1048x - 1054. Then you find the zeroes ( the points in which the the graph intersects with the x-axis). Finally, you set y equal to zero and find the x.

The equation of a circle with radius r and center at point (a, b) is given by
(x - a)^2 + (y - b)^2 = r^2
1.) For the circle given by x^2 + y^2 = 24
(x - 0)^2 + (y - 0)^2 = (√24)^2
Therefore, center = (0, 0) and radius = √24 = 4.9 units

3.) x^2 + y^2 -10x -2y = -10
x^2 - 10x + (-5)^2 + y^2 - 2y + (-1)^2 = -10 + (-5)^2 + (-1)^2
x^2 - 10x + 25 + y^2 - 2y + 1 = -10 + 25 + 1
(x - 5)^2 + (y - 1)^2 = 16
(x - 5)^2 + (y - 1)^2 = 4^2

Is 10^5 an exponents for 100,000
Masja [62]
Yes, because 10 x 10 x 10 x 10 x 10 (which equals 10^5) is equal to 100,000.
Remember, 10 to the power of anything (like 8, 5, or 9) just means that you have to count out however many zeros the exponent tells you to, which in this case, is five.

Find the preimage of the point (4, 3) under the given transformation. A transformation T : (x, y) (x - 2, y + 3) (2, 6) (2, 3) (
Mashcka [7]

Answer:

The preimage is (6,0)

Step-by-step explanation:

The given point is (4,3).

The translation rule is

T:(x,y)\rightarrow (x-2,y+3)

Let (a,b) be the preimage.

Then,

We apply this rule to the preimage to obtain;

T:(a,b)\rightarrow (a-2,b+3)

This implies that;

a-2=4

\Rightarrow a=4+2

\Rightarrow a=6

Also,

b+3=3

\Rightarrow b=3-3

\Rightarrow b=0

Hence the preimage is (6,0)
