Answer:
12.566
Step-by-step explanation:
A = ∫1/2(r)^2dtheta from a - b = 0 to 2π
∫1/2(sin^2theta-4sintheta+4)dtheta
[9/4theta+2costheta-1/8sin2theta] from 0 to 2π…
when you solve this you get 14.137 without taking out the cos(2theta+3)
Answer:
x = 12z + 1 and y = 10z - 1
Step-by-step explanation:
To solve the system of equations, we can use the substitution method
If we call
3x - 4y + 4z = 7 I
x - y - 2z = 2 II
2x - 3y + 6z = 5 III
Clearing II x = 2 + y + 2z
Now, replacing II in III
2(2 + y + 2z) - 3y +6z = 5
4 + 2y + 4z - 3y + 6z = 5
10z - y = 1 from here y = 10z - 1
Finally, replacing y in I
3x - 4(10z - 1) + 4z = 7
3x -40z + 4 + 4z = 7
3x - 36z = 3
3x = 36z + 3
x = 12z + 1
Done
Answer:
No
Step-by-step explanation:
y = 2x -1
Substitute the point into the equation
4 = 2(3) -1
4 = 6-1
4 =5
This is not a true statement so the point is not on the line
The answer for your question is A.
-12<x<4
Answer:
32
Step-by-step explanation:
To compare how much more Lola hiked we need the miles that each one hiked.
Elton hiked 16 miles each day for 12 days, the total amount of miles he hiked we can found by multiplying 16 by 12:
16miles(12) = 192 miles
Lola hiked 14 miles each day but for 16 days, so the total amount of miles she hiked can be found by multiplying 14 by 16:
14miles(16days) = 224
The difference of miles we found by subtracting 192 (elton's miles) from 224 (lola's miles)
224 - 192 = 32
