Answer:6.5
Step-by-step explanation:
Angle C is 90° therefore we can apply Pythagoras principle to get the diameter Of The circle
Diameter=√(12^2+5^2)
Diameter=√(12x12+5x5)
Diameter=√(144+25)
Diameter=√(169)
Diameter=13
Radius=diameter ➗ 2
Radius=13 ➗ 2
Radius=6.5
Answer:
I can't tell u the answer but brackets always comes first.
Answer:
(1) 13.0 years
(2) {-1728, 1728}
Step-by-step explanation:
(1)
Compound annually:
= A
(47000) = 79200
=
ln() = ln()
ln and e cancel out.
(0.04)(t) = ln()
t =
t = 13.0 years
(2)
Substitute y with -4x.
Solve for x.
x = {-3, 3}
Plug in x values into any equation to find y.
y = -4(-3) and y = -4(3)
y = {-12, 12}
= = -1728
= = 1728
Start with he equation
3.5t + 4t = 4 - I did this since the walked the same amount of time and the total distanace covered was 4 miles
7.5t = 4
t = 0.53 hours
Answer: The two equations are - (7x -5) = 39 or 7x - 5 = 39
