1.
a. let k = constant
k = y/x
so k = 14/2 = 7
b. the equation would be y = 7x
2. a. k = y/x = 25/5 = 5
b. y = 5x
c. 50 = 5x, x = 50/5 = 10
X=+-4
positive and negative 4
294 cm^2 = 6 * r^2 (the cube has 6 faces)
so the radius is 7 cm
the volume is 7^3 cm^3 = 343 cm^3
If you are doing a multi step question that looks something like this: 23+(4)-4 or longer. You will have to use a formula called BEDMAS. It stands for brackets, exponents( which are little numbers on top of a number), then you deal with division, multiplication, addition, and subtraction. You will have to solve your equation in this order. If you don’t you will get another, answer.
<span>p ← 1
s ← 0
for i is in {1, 2, 3, 4}
do p ← p · 3
s ← s + p
n = 1 => first iteration
p = 1 * 3 = 3
s = 0 + 3 = 3
number of multiplications ---> 1
n = 2
p = 3 * 3 = 9
s = 3 + 9 = 12
number of multiplications ----> 1 + 1 = 2
n = 3
p = 9 * 3 = 27
s = 12 + 27 = 39
number o multiplications --> 2 + 1 = 3
n = 4
p = 27 * 7 = 81
s = 39 + 81 = 120
final number of multiplications -----> 3 + 1 = 4
final value of s
s = 120
Answer: number of mujltiplications: 4
final value of s: s = 120.
