The associative property states that you can add or multiply regardless
of how the numbers are grouped. By 'grouped' we mean 'how you use
parenthesis'. In other words, if you are adding or multiplying it does
not matter where you put the parenthesis. Add some parenthesis any where
you like!.
Answer:
20m
Step-by-step explanation:
Given the formula that modelled the height given as;
h=30+40t-5t^2
At t = 4s
h=30+40(4)-5(4)^2
h = 30+160-80
h = 160-60
h = 110m
At t = 2s
h=30+40(2)-5(2)^2
h=30+80-20
h = 110-20
h= 90m
Difference in height = 110-90 = 20m
Hence the height is 20m higher above the ground at 4s than at 2s
Answer:
= 9.2195 = 9.22
= 4.123
Step-by-step explanation:
Write 9x - 3y = -6 in slope-intercept form. Make sure you show all steps and inverse operations
<em><u>Answer:</u></em>
y = 3x + 2 is the slope-intercept form of given equation 9x - 3y = -6
<em><u>Solution:</u></em>
Given that we have to write 9x - 3y = -6 in slope intercept form
<em><u>The slope intercept form is given as:</u></em>
<h3>y = mx + c</h3>
Where "m" is the slope of the line and "c" is the y - intercept
Let us convert the given equation into slope intercept form
9x - 3y = -6
Keep the variable "y" on one side and move the remaining terms to other side
9x + 6 = 3y
3y = 9x + 6
Move the coefficient of "y" from L.H.S to R.H.S
Distribute to terms inside bracket
Simplify the above equation
Thus the slope intercept form is found
Step-by-step explanation:
P = IV
2000 W = I (120 V)
I = 16.7 A
P = E/t
P = (2000 W × 8 hr) / (1 day)
P = 16,000 W·hr/day
P = 16000 W·hr/day × (365 day / yr)
P = 5,840,000 W·hr/yr
P = 5,840,000 W·hr/yr × (1 kW / 1000 W)
P = 5840 kW·hr/yr
C = 5840 kW·hr/yr × (0.25 $/kW/hr)
C = $1460/yr
