If the diameter is 10.5 then the radius is 5.25.
This is because the radius of a diameter is half the diameter.
So
10.5/2
= 5.25
Therefore the radius is 5.25
Given:
The equation of line is

To find:
The x and y-intercept of the given line.
Solution:
We have,

Putting x=0, we get

Add 6 on both sides.


Divide both sides by 4.

So, the y-intercept is
.
Putting y=0 in given equation, we get

Add 5 on both sides.


Divide both sides by 7.

So, the x-intercept is
.

Answer:6√3
Explanation:Before we begin, remember the following:
Now, for the given:75 can be written as 25*3
This means that:

Applying the above concept, we can find that:

Now, we know that:
√25 = 5 (we ignored the negative value)
This means that:
√75 = 5√3
Finally, we can compute the needed sum as follows:
√75 + √3 = 5√3 + √3 = 6√3
Hope this helps :)
