Answer:
Final Answer 25.12
Step-by-step explanation:
This is very simple you can use two formulas to find the circumfrence of the circle. You can either use C=2πr or C=πd.
For this problem you will be using C=2πr since r is radius and the radius is 4.
C=2*3.14*4
C=6.28*4
C=25.12
Hope this helps.
Answer:
X=$5000 in sales
Step-by-step explanation:
You can write an equation in slope-intercept to find an answer.
<em>y=0.2x+1000</em>, 20% commission is the slope and the base pay is the y-intercept.
Now, just plug in 2000 for y.
<em>2000</em><em>=</em><em>0.2x</em><em>+</em><em>1000,</em><em> </em>subtract 1000.
<em>1000</em><em>=</em><em>0.2x,</em><em> </em>Multiply by 5 to get x by itself.
<em>5000</em><em>=</em><em>x</em><em>.</em>
Answer:
x is 5 and B is 66°
Step-by-step explanation:
Since the two lines are parallel then
A + B = 180°
8x + 74 + 2x + 56 = 180
Then x is 5
Since B is 2x + 56.
Then B is 2(5)+56=66°
Very simple. You just use the vectors as normal numbers, and multiply the coordinates with 2 and 4 like this:
2*u = 2* (2,4) = (4,8)
4*w = 4* (-1,3) = (-4,12)
(4,8) - (-4,12) = (8,-4)
So the vector has the coordinates (8,-4)
Answer:
5.25
Step-by-step explanation:
If CD is perpendicular to AB, a right angle is formed by the perpendicular lines at the base of the triangle. If we know that AB is 3 we can divided that by two to use half the triangle and create a right trianle with a base of 1.5 (half of 3) a height of rad 3 now all we have to do is use P-Thags to find AC which is the hypotenuse. After doing 1.5 squared + rad 3 squared = ac squared you will get the answer of AC = 5.25
