I already answered this question
<span>17 1/3 + (-50 1/3) -5 1/2
= -33 - 5 1/2
= (</span>-33 ) + ( - 5 1/2)
<span>= -38 1/2
</span>= -38.5
The derivative of x^3 is 3x^2.... is that what you were looking for?
Answer:
c)
Step-by-step explanation:
y = mx +c
c is y-intercept. At y-intercept , x = 0.
So, from the table, c = -5
y = mx - c
Choose any point from the table and Plugin the values in the above equation.
(4 , 1.4)
1.4 = m*4 - 5
1.4+5 = 4m
6.4=4m
6.4/4 = m
1.6 = m
y = 1.6x - 5
We are given the electricity cost as 5 cents per
kilowatt-hour. We should notice that the cost is actually in the form of:
electrical cost = cost / (power * time)
Therefore to get a number which is in terms of cents
alone (cost alone), therefore we should multiply the given electrical cost
value with the power and time.
Power = 80 watt = 0.08 kilowatt
Time = 24 hours
Therefore the cost is calculated as:
cost = electrical cost * power * time
cost = [5 cents / (kilowatt hour)] (0.08 kilowatt) (24
hour)
cost = 9.6 cents
Answer:
<span>9.6 cents</span>
<span>So we want to know what is the area of the shaded reagion that consists of a circle inside a square If the side of the square is a=10cm. For that we simply calculate both areas and subtract the area of a circle from the area of a square: area of a square A=10^2=100 cm^2, area of a circle B=pi*r^2 where r=a/2. So: B=3.14*5^2=78.5cm^2: A-B=100-78.5=21.5cm^2 So the correct answer is D</span>
