Answer:
m = 3/2
b = -3
Equation:
y = 3/2x - 3
Step-by-step explanation:
m = rise/run
rise = 3
run = 2
b = y-intercept
y-intercept is -3
Equation: y = mx + b
y = 3/2x + (-3)
y = 3/2x - 3
Answer:
= 1099 cm^2
Step-by-step explanation:
The surface area of a cylinder is found by using the formula
SA=2πrh+2πr^2
We know the diameter. To find the radius, we take the diameter and divide by 2.
r =d/2
r =14 cm/2 = 7 cm
h = 18 cm
Substituting what we know
SA = 2 * pi * 18 * 7 + 2 * pi * (7)^2
= 252 *pi + 2* pi *49
= 252 pi + 98 pi
= 350 * pi
Let pi be approximated by 3.14
SA = 350 * 3.14
= 1099 cm^2
The determinant is found by the formula ad-cb
where the letters are: a and b is the top row and c and d is the bottom row
so ad = 12*2 and cb = -6*0
12x2 = 24
-6x0 =0
24-0 = 24
the determinant = 24
Step-by-step answer:
It is not clear what the question exactly wants, but here's the best I can do with possible interpretations.
Let P(t) = population t years after 2000, then
P(t) = (N0)e^(Rt)
where
N0=population of year 2000 = 19169000
R=rate of growth, in ratio = 0.006
e=base of natural logarithm = 2.7182818284...
Then
P(25) = 19169000*e^(0.006*25)
= 19169000*e^(0.15)
= 22271200.59885846
= 22271201
Not sure what it means "the other value", as we only have one.
Answer:
21 kids have to go on the trip to make the museum a better deal
Step-by-step explanation:
Zoo: y=10x+100
Museum: y=5x+200
10x+100=5x+200
5x=100
x=20
When 20 kids go on trip the costs will be the same. Therefore, once 21 kids go the museum will be cheaper then the zoo as it is increasing at a rate of 5 dollars
