The line perpendicular to the y-axis is the x-axis.
Required equation is y = 0
A
The initial amount is $50
It is doubled every month
And 2 dollars is added by the bank
Therefore, the equation becomes:
Next = 2 x now + 2, starting at 50
Answer: D
Step-by-step explanation:
Formula: A = 2(wl+hl+hw)
A = 2(5*3 + 7*3 + 7*5)
A = 2(15 + 21 + 35)
A = 2(71) = 142 sq inches
Answer:
h=-16t^2+ 30t+4.
Step-by-step explanation:
For the table you just plug in the <em>t</em> (time) into the equation. So for the first one we have 0 seconds. So you plug in the 0 where it says <em>t</em>. So the equation becomes h=-16*0^2+30*0+4. Which gives us 4 <em>h</em>(height). Then you keep pluging in the time into the equation.
Time <em>t </em>in seconds 0 .5 1 1.5 2
Height <em>h </em>in feet 4 15 18 13 0
The perimeter is equal to 60 feet and has the formula:
Perimeter = 2 l + 2 w
60 = 2 l + 2 w
The area is equal to 200 square feet and has the formula:
Area = l w
200 = l w
Rewriting area in terms of l:
l = 200 / w
Combining this with the perimeter formula:
60 = 2 (200 / w) + 2 w
60 = 400 / w + 2 w
Multiplying all by w:
60 w = 400 + 2 w^2
Dividing by 2 and rearranging:
w^2 – 30 w = - 200
Completing the square:
(w – 15)^2 = - 200 + (-15)^2
(w – 15)^2 = 25
w – 15 = ±5
w = 10, 20
Hence the dimensions of the garden is 10 feet by 20 feet
