Answer:
<h2>48</h2>
Step-by-step explanation:
It's an arithmetic sequence with common difference <em>d = 7</em>.
Find 9th term.
METHOD 1<em>.</em>
<em>Calculate next terms:</em>
METHOD 2.
<em>The explicit formula of an arithmetic sequence:</em>
Substitue:
<em>use the distributive property</em>
Put <em>n = 9</em>:
We know that the interest decreased by 29.3%, therefore
what was left now is simply just 70.7% of the original, therefore we divide
this by 0.707
rate = 7.7% / 0.707
rate = 10.89%
<span>So the rate was 10.89% 10 years ago</span>
Angle q and angle t
angle j and angle k
Given that Pythagorean Theorum is
A^2 + B^2 = C^2, you need to do the opposite.
To find for A^2, you need to:
Subtract B^2 from C^2. This creates the equation of:
C^2 - B^2 = A^2. This works because A^2 + B^2 is C^2, so the opposite must work.
Now if you're looking for A and not A^2, you need to subtract B^2 from C^2 and then square root the difference.
I hope this helps!
Well to make this easier convert the 81% into a decimal also which is 0.81 so the answer would be .81 * .163 and that equals 0.132
