Answer:
$0.03 per inch
Step-by-step explanation:
We need to convert 8 meters to inches first.
Unit ratio for meters to cm is:
So 8 meters is 800 cm
Now,
we need to convert 800 cm to inches
Unit ratio for cm to inches is:
So, 800 cm is :
inches
To get costing per inch, we divide total cost ($10) by the total number of inches (which is 314.96):
Rounded to nearest hundredth, $0.03 per inch
According to the degree of freedom, if there are two unknowns to be determined, there should be two equations that are independent. In this case, the two equations y = 4^x and y = 2^x + 2. We equate the two equations to get x and y. x is equal to 1 and y is equal to 4. To solve the equation graphically, we plot the two graphs and see the point of intersection.
Answer: D
To show work is plug the the x-coordinates for the points given.
Example:
x=2
y=-(1/4)x^2
y=-(1/4)2^2
y=-(1/4)4
y=-1

Answer: $66.7
Step-by-step explanation:
Answer:The equation for inverse proportion is calculated as xy=k.
When 20 people attend the picnic, the cost for each person was $50, then k will be= 20 × 50 = 1000
Recall that k = xy
For the second aspect of the question, x= 15, k= 1000.
k= xy
y = k/x
= 1000/15
= 66.7
If 15 people attend the picnic instead, the cost per person will be $66.7
Answer:
T = 200 months
Step-by-step explanation:
Given the model to be
dp/dt = p(10-1-10-7p) where p(0) = 6000
dp/dt = p(-1-7p)
dp/dt = -p+7p²
But since P(0) = 6000
We plug this value into the equation
P = -6000+7(6000)²
P = -6000+252000000
P = 251994000. .limiting value
Differentiating dp/dt w.r.t p
dp/dt = -1+14p
dp'/dt = 14p-1
Plugging p(0) = 6000 into the above we have that
dp'/dt = 14(6000)-1
P' = 84000
Time population would be equal to 3/2 the limiting value
T = 3/2× 84000 = 126000
T = 25199400/126000
T = 199.99months
T = 200 months.
