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
set it up like a y= equation.
which would be y=-x^2+7
to find the vertex, you substitute the 0s.
so 0=-(0)^2+7
-0^2=0
0+7=7
0=7
(0,7)
Answer: See explanation
Step-by-step explanation:
1. Step 1: Add up all the numbers.
12 + 15 + 10 + 15 + 11 + 12 + 15 = 90
Step 2: Count how many numbers there are.
There are 7 numbers
Step 3: Divide the sum of the numbers by amount of numbers.
90 ÷ 7 = 12.85
12.85 ≈ 12.9
Mean = 12.9 in tenth place or 13 in whole place
2. The mode is the number that appears the most
15 appears 3 times.
3. 38 / +38
4. 1 week = 7 days
7 × 2 = 14
9 weeks = 9 × 7 = 63
63 × 3 = 189
189 + 14 = 203
203 miles in all
5. Area of 1st rectangle: b × h
4 × 14 = 56
Area of 2nd rectangle: b × h
4 × 14 = 56
56 + 56 = 112
Area of polygon = 112
Hope this helps!
