Answer:
k = 9
Step-by-step explanation:
Calculate the slope m using the slope formula and equate to 8
m = 
with (x₁, y₁ ) = (- 1, 1) and (x₂, y₂ ) = (0, k)
m = 
= k - 1 = 8 ( add 1 to both sides )
k = 9
<span>Martin deposits $200
in a savings account that earns 5% annual interest.
year interest balance
1 200 * 5% 200(1.05)
2 200(1.05) * 5% 200(1.05)^2
3 200(1.05)^2*5% 200(1.05)^3
y 200(1.05)^y
=> m = 200 (1.05)^y

0.5a - 0.3 = 5
Add 0.3 to both sides:
0.5a = 5.3
Divide both sides by 0.5:
a = 10.6

Step-by-step explanation:
We need to find the surface area of the pyramid. The pyramid can be divided into 4 triangles and one square (the bottom).
Area of a triangle is 1/2*b*h where b is the base of the triangle and h is the height.
Area of a square is length times width.
Total area =
