Answer:

Rent in 10th year = $5345.90

Step-by-step explanation:

Rent of apartment during first year = $1800 per month

But growth in rent with 11.5% per year will be represented by the exponential function,

Rent in 't'th year = $\text{Initial rent}(1+\frac{\text{Growth rate}}{100})^{\text{time}}$

= $1800(1+\frac{11.5}{100})^t$

= $1800(1.115)^t$

Therefore, rent during 10th year will be,

Rent in 10th year = $1800(1.115)^{10}$

= $5345.90

Easy all you have to do is do 3 + 9 equals 20 which we all know that because we're in high school haha anyways back to what you do 3 + 9 which equals 12 we do we have to flip it around so if you sent it around it will be 12 equals 9 + 3 no I just read it so it would be 12 plus 9 which equals 3 which we know that so you have to flip the device which is going to eat with 3 or 12 - 9 which is going to eat you 3 that's what I'm going to put with that

Fiind the value of x between 0 and 360 <br>for question 5sin 2x=7cos2x

Degger [83]

Answer:

x=pi*n/2+1/2arctan(7/5)

Step-by-step explanation:

5sin(2x)=7cos(2x)

5tan(2x)=7/5

2x=pi*n+arctan(7/5)

x=pi*n/2+1/2arctan(7/5) for n e Z

If you were to move use the substitution method to solve the following system choose the new equation after the expression equiv

yanalaym [24]

Solve x+4y = 13 for x by subtracting 4y from both sides.

We end up with x = -4y+13.

Since x and -4y+13 are the same, we can replace every x in the first equation with -4y+13

2x-3y = -29

2( x ) - 3y = -29

2( -4y+13 ) - 3y = -29 ... x is replaced with -4y+13

The answer is choice B

Which are true if figure DEFG is reflected across the x-axis? Check all that apply.

meriva

Answer: The correct options are 1,2 and 3.

Explanation:

If a figure reflected across the x-axis then the x-coordinate remains same but the sign of y-coordinate changes.

According to the reflection rule across the x-axis,

$(x,y)\rightarrow(x,-y)$

From the given figure it is noticed that the coordinate of point D(0,4) and E(-2,0).

After reflection,

$D(0,4)\rightarrow D'(0,-4)$

$E(-2,0)\rightarrow E'(-2,0)$

Therefore the option 1 and 2 are correct.

From the given figure it is noticed the distance of point G from the x-axis is 2, therefore the distance from the G' to x-axis is also 2, because the distance of preimage and image are equal from the line of reflection.

Therefore, the option 3 is correct.

From the given figure it is noticed the distance of point D from the x-axis is 4, therefore the distance from the D' to x-axis is also 4.

Therefore, the option 4 is incorrect.

From the below figure it is clearly noticed that the orientation will not be preserved. Because the sides are not equal, so the reflection will change the orientation.
