Hi there! :)
Find the area of the shape using the formula for the area of a trapezoid:
A = 1/2(b1 + b2) · h
Where:
b1 = base 1
b2 = base 2
h = height
A = area
Plug in the given bases and height:
A = 1/2(7.5 + 2.5) · 2.5
Simplify:
A = 1/2(10) · 2.5
A = 5 · 2.5
A = 12.5 units²
9514 1404 393
Answer:
D
Step-by-step explanation:
The given line's equation is in slope-intercept form:
y = mx + b
where m = -4 is the slope, and b = -1 is the y-intercept.
The slope of the perpendicular line will be ...
-1/m = -1/(-4) = 1/4
You want the point-slope equation for the line, which is ...
y -k = m(x -h) . . . . line with slope m through point (h, k)
Your equation will have m=1/4, (h, k) = (-2, 7), so it will be ...
y -7 = 1/4(x +2)
-4b - 2c =
(-4 × 2.5) - (2 × 3)
-10 - 6
= -16
So, -4b - 2c = -16
Hope this helps and let me know if anymore help is needed!!
Answer:
A. 4000 meters because
1 km = 1000 meters
and 4 km = 1000 × 4 = 4000
