Im not sure but download this app is called socratic there you will find everything
Answer:
Diameter = 14 cm
Circumference = 44 cm
Step-by-step explanation:
- Area of circle = πr²
- Diameter = 2r
- Circumference = 2πr = πd
- π ≈ 3.142
Answer:
3 + 3/4x
Step-by-step explanation:
it is 3 up and 4 left so y over x for the the slope. mx +b
Answer:
8 units
Step-by-step explanation:
Hello!
So, there's a formula we can apply to right-angled triangles: Pythagorean's theorem. It states that c = , where <em>c</em> is the hypotenuse and <em>a</em> and <em>b </em>are the legs of the triangle.
So, from the problem, if <em>c </em>= 17 and <em>a </em> = 15, then, we're solving for <em>b</em>. So we'll rewrite the theorem to solve for <em>b</em>.
Okay, so now we have isolated the theorem for <em>b. Let's </em>plug in our values for <em>c </em>and <em>a</em>.
So, using the theorem, we found <em>b</em> = 8. To check our work, let's plug in <em>b</em> and <em>a</em> and solve for <em>c.</em>

So, we got our hypotenuse to equal 17 units, which is correct! So, our <em>b</em> is correct too. Awesome
