Answer:

QR = sqrt(147)

Step-by-step explanation:

Since this is a right triangle, we can use the Pythagorean theorem

a^2 + b^2 = c^2

7^2 + QR^2 = 14^2

49 + QR^2 = 196

QR^2 = 196-49

QR^2 = 147

Taking the square root of each side

QR = sqrt(147)

Bingel [31]

Answer:

(a) {-3, 2}

(b) {3, 4}

Step-by-step explanation:

The high points are (-3, 3) and (2, 4).

The x-values at which the function has a local maximum are {-3, 2}.

The local maximum values are {3, 4}.

Your answer box probably doesn't want the curly brackets and maybe not the spaces, either. Those brackets are used to identify a set of values.

Data plays a crucial role in decision-making because it can reveal relationships between different quantities. We often use line

mote1985 [20]

Answer:

(a×b)×c = 0 means that vector c parallel to vector (a×b). But because (a × b) ⊥ a and (a -b) ⊥ b so

c ⊥ a and c ⊥ b.

Hope this helps, have a nice day! :D

How do I show my work for solving the radius of a circle if the area is 78.5 cm^2

SIZIF [17.4K]

9514 1404 393

Answer:

radius = 5 cm

Step-by-step explanation:

The point of "show your work" is to have to do exactly that. If you know the answer to the problem, you are being requested to show how you got it. If you got it by using a web calculator, then show your input and its result.

If you worked the problem yourself, you probably did it by filling in numbers in the equation for the area of a circle:

A = πr²

78.5 = 3.14×r²

Dividing both sides by 3.14 gives the square of the radius:

78.4/3.14 = r² = 25

Taking the positive square root gives the radius:

r = √25 = 5

The area is in square centimeters, so the radius is in centimeters:

radius = 5 cm
