When working with the square root of a number, when would you have only a positive answer and when would you have both a positiv

Rama09 [41]

<span>Lets make it clear: You would have a positive answer when the value you are looking for has to be a positive number. On the other hand you would have a positive and a negative answer when you take the square root of something that doesn't have to be positive. it could be either because when a negative number is squared it becomes positive and when a positive number is squared it stays positive as well.</span>

Determine the radius of a circle if a 24-inch chord is 9 inches from the center.

bixtya [17]

Hi! :)

The radius of a circle is the length from the perimeter of the circle to the center of the circle.

If 24 inches is still 9 inches from the center, you just have to add 24 and 9 to get the radius.

24+9= 33

Your final answer should be that the radius is 33 inches.

Hope this helps!

Question 11-(3 marks available)

klasskru [66]

Answer: 1080 $cm^{2}$

Determine the values of b1, b2, and b3, the sides of the triangular base. Also determine the value of h, the height of the triangular base and l, the length of the prism (the length between the bases).

The sides of the triangular base are:

b1 = 13 in.

b2 = 14 in.

b3 = 15 in.

The triangular base is a right triangle, and so the height is one of our sides. We will use

h = 12 in.

The length of the prism is

l = 20 in.

total surface area = bh + (b1+b2+b3)*l

bh = 12*20 = 240 $cm^{2}$

l * (b1+b2+b3) = 20*(13 + 14+ 15) = 840 $cm^{2}$

TSA = bh + l * (b1 + b2 + b3) = 240 + 840 = 1080 $cm^{2}$
