ANSWER: 3

image at the bottom to help you visualize!

First, Let's graph point A:

( The red point )

Now reflect point a across the X axis which is the horizontal line (to get point B):

( The blue point )

We see that --> in the point (5,-3), the y coordinate, (-3) changed to (3)

SO THE ANSWER WOULD BE: 3

Summary:

When you reflect a point across the x-axis, the x-coordinate remains the same, but the y-coordinate is transformed into its opposite (its sign is changed).

When you reflect a point across the y-axis, the y-coordinate remains the same, but the x-coordinate is transformed into its opposite (its sign is changed).

HOPE THIS HELPS!

When your doing a reflection over the X axis you want to switch the X cordinate that you are give to the opposite of +/- like if (-5,3) and your flipping it over the X axis it would be (5,3) but in this case your flipping it over the Y axis and you need to switch the Y cordinate to the opposite number so (5,-3) is your original number and when you flip it over the Y axis it would make it (5,3)

Please solve the following sum or difference identity.

xxTIMURxx [149]

Answer:

$sin(A - B) = \frac{4}{5}$

Step-by-step explanation:

Given:

$sin(A) = \frac{24}{25}$

$sin(B) = -\frac{4}{5}$

Need:

$sin(A - B)$

First, let's look at the identities:

sum: $sin(A + B) = sinAcosB + cosAsinB$

difference: $sin(A - B) = sinAcosB - cosAsinB$

The question asks to find sin(A - B); therefore, we need to use the difference identity.

Based on the given information (value and quadrant), we can draw reference triangles to find the simplified values of A and B.

sin(A) = $\frac{24}{25}$

cos(A) = $\frac{7}{25}$

sin(B) = $-\frac{4}{5}$

cos(B) = $\frac{3}{5}$

Plug these values into the difference identity formula.

$sin(A - B) = sinAcosB - cosAsinB$

$sin(A - B) = (\frac{24}{25})(\frac{3}{5}) - (-\frac{4}{5})(\frac{7}{25})$

Multiply.

$sin(A - B) = (\frac{72}{125}) + (\frac{28}{125})$

Add.

$sin(A - B) = \frac{4}{5}$

This is your answer.

Hope this helps!

The volume of air in a balloon is represented by the function V (r) = four-thirds pi r cubed, where r is the radius of the ballo

Deffense [45]

Answer: You do not need calculus for this problem, as it is currently stated. Is something missing from the problem statement? If not, then just find the difference between the volumes. That will be the additional air required to inflate from the lower volume to the higher volume. For r in inches and V(r) in inches cubed,

V1(r) = (4/3)πr3

V2(2) = (4/3)π(r + 1)3

V2(r) - V1(r) = (4/3)π[(r + 1)3 - r3]

That is your function. You can simplify it further if you wish.

brainliest answer plz

hope this helps BTW
