Hello!
When you're finding the midpoint, you're looking for the point on the line in the middle of the two endpoints.
To do this, all you have to do is find the number in between the two x coordinates, and between the two y coordinates.
The two x coordinates are -3 and 2. The number perfectly in between these two is -0.5, meaning that the x coordinate of our midpoint is -0.5. The two y coordinates are -2 and 3, and the number perfectly in between these is 0.5, so the y coordinate is 0.5.
Therefore, your answer is C, (-0.5, 0.5).
Hope this helps!
Answer:
(2,7)
Step-by-step explanation:
First multiply the exponents. You will get 3 to the power of 12: 531441. Multiply this by 30 and you have 15943230
Answer:
26hr
Step-by-step explanation:
12 calls/hr
480 calls/wk
If Juanita has made 168 calls this week, it meants she still has to make 312 calls. So, 312 calls ÷ 12calls/hr = 26hr
Juanita needs to work 26hr mores to reach the weekly goal.
Answer:
8.4 (rounded to 1 dp)
Step-by-step explanation:
1) Identify the number of angles and sides given if you cannot use Pythagoras or SohCahToa.
2) You have 2 angles and 1 side, so you know you must use sine rule: <em>a </em>over sinA =<em> b </em>over sinB
<em>a</em> = side length, sin(A) = angle opposite side
<em>b</em> = side length, sin(B) = angle opposite side
3) This means:
13/sin(90) = x/sin(40)
4) rearrange for x:
x = 13/sin(90) * sin(40)
= 8.356...
5) Round to however many sig figs/dps they're asking for
Example: 1 dp
AB = 8.4
3 sig figs
AB = 8.36
