Area of aqua: A = bh/2 = (13.4cm) (4cm)/2 = 26.8cm2
Total area trapezoid: A = (a+b/2)h = ((13.4cm + 18cm)/2) 4cm = 62.8cm2
Area of purple = Total area - area of
aqua = (62.8cm2) - (26.8cm2) = 36cm2
Answer:
the missing angle is 130
Step-by-step explanation:
180-50=130
Answer:
See below ↓
Step-by-step explanation:
The relation is :
- Let y = Motor Speed and x = Voltage
- y = 25x
<u>Title</u> : Variation of Motor Speed with Applied Voltage
<u>x-axis label</u> : Voltage (volt)
<u>y-axis label</u> : Motor speed (rpm)
As it constantly varies with a value of x and they are not isolated data points, they should be connected with a line.
Answer:
-19
Step-by-step explanation:
Evaluate -x^2 - 5 x y + 5 y^3 where x = -2 and y = -1:
-x^2 - 5 x y + 5 y^3 = -(-2)^2 - -2 (-5) + (-1)^3×5
(-2)^2 = 4:
-4 - -5 (-2) + 5×(-1)^3
(-1)^3 = -1:
-4 - -5 (-2) + 5×-1
-5 (-2) = 10:
-4 - 10 - 5
-4 - 10 - 5 = -(4 + 10 + 5):
-(4 + 10 + 5)
