For 9, do 0.5*6*9.2*5 to get the total area of the visual triangles, add that to 0.5*6*4.1*5 to get the area of the pentagon and you should get 199.5 cm^2for 10, do 0.5*6.9*8*12 to get the total area of the figure and you should get 331.2 cm^2
I think that the answer is D. because 8+6=14 so yeah
A10 =9
a11= 9 x -2 = -18
a12= -18 x -2 = 36
a13 =36 x -2 = -72
multiplies by -2 every time
Answer:
Step-by-step explanation:
A "difference" indicates subtraction is being used. The difference between these 2 numbers is found the same way we find the distance between 2 points on a number line. Since both the difference and the distance have to be positive numbers, the formula to find it is
|a - b| which is the absolute value of a - b.
If a = -52 and b = -79:
| -52 - (-79) | = | -52 + 79 | = 27 OR
If a = -79 and b = -52:
| -79 - (-52) | = | -79 + 52 | = | -27 | = 27
Answer:
Step-by-step explanation:
<u>Given points:</u>
<u>Slope is:</u>
- m = (y2 - y1)/(x2 - x1)
- m = (-5 - 1)/(8 - (-2)) = -6/10 = -3/5
- m = -3/5
<u>Use formula y = mx + b, substitute x = -2, y = 1, m = -3/5, find y-intercept b:</u>
- 1 = (-3/5)*(-2) + b
- 1 = 6/5 + b
- b = 1 - 6/5
- b = - 1/5
Correct option is B.
