Answer:
5 units
Step-by-step explanation:
The horizontal length is 4 units and the vertical length is 3 units
Consider the right triangle formed by the line, horizontal and vertical.
Using Pythagoras' identity with the line as the hypotenuse h , then
h² = 4² + 3² = 16 + 9 = 25 ( take square root of both sides )
h = = 5
The line is 5 units in length

Answer:
9.694 years
Step-by-step explanation:
Let the investment is $P.
So, we are asked to determine the time it will grow to triple with the compound interest rate of 12%.
Let the time is y years.
So, from the formula of compound interest we can write
⇒
⇒
Now, taking log both sides we get,
y log 1.12 = log 3 {Since, }
⇒ 0.04922y = 0.477712
⇒ y = 9.694 years (Answer)
Hello!
First we will get the variable in the correct side.
add 4c to 7c.
Second thing you will do is subtract 12 from 78
Now, divide 66 by 11 and you'll be left with c=6

Answer:
Step-by-step explanation:
1). Equation that represents the volume of a cylinder,
V = πr²h
Here, r = radius of the cylinder
h = Height of the cylinder
2). Fromm the given formula of volume,
r(In m) V(In cubic meters)
1 56.55
2 226.19
3 508.94
3). If the radius is doubled from 1 m to 2 m,
At r = 1 m, Volume (V₁) = 56.55 m³
At r = 2 m, Volume (V₂) = 226.19
= 4
Therefore, volume is not doubled when radius of the cylinder is doubled.
