A circle is graphed with its center on the origin.The area of the circle is 49 square units.What are the coordinates of the x-in
neonofarm [45]

Answer:

3.95 and -3.95

Step-by-step explanation:

To graph a circle you can use the formula or (x – h)^2 + (y – k)^2 = r^2. So substituting in the given, we get x^2+y^2=49/pi. The x intercept is when y=0. So x^2=49/pi and so

x = sqrt(49/pi) and rounding to the nearest tenth, we get 3.95 and -3.95 because it isn’t a principal square root.

DiKsa [7]
Good question!

First of all, you need to be aware of the following trigonometrical ratios\functions:

For angle A:

adjacent=12
opposite=35
hypotenuse=37

Hence:
cos(A)= \frac{12}{37} &#10;\\~\\&#10;sin(A)= \frac{35}{37} &#10;\\~\\&#10;tan(A)= \frac{35}{12}

I hope that helps!



I am with you if you faced any difficulties!

What is the opposite of -3.4
lina2011 [118]

Answer:

3.4

Step-by-step explanation:

The opposite of a number is the same as the additive inverse of the number.

Two numbers are opposites, or additive inverses, if they add to zero.

For a positive or a negative number, just change its sign to find its opposite. For zero, its additive inverse is zero.

The opposite of -3.4 is 3.4.

Answer: 3.4
