3^y=12 use your answer to solve log
Answer:
12/log3
Step-by-step explanation:
Hope it helps you
Answer:
y ≈ 2.262
Step-by-step explanation:
Using the rule of logarithms
log[tex]x^{n}[/tex] = nlogx
Given
[tex]3^{y}[/tex] = 12 ( take log of both sides )
log[tex]3^{y}[/tex] = log12 , then
ylog3 = log12 ( divide both sides by log3 )
y = [tex]\frac{log12}{log3}[/tex] ≈ 2.262 ( to 3 dec. places )

Jenny measured 1/3 cup of flour and 3/8 cup of flour. How many total cups of flour did Jenny measure?
Rewrite the fractions to have a common denominator:
1/3 = 8/24
3/8 = 9/24
Now add:
8/24 + 9/24 = 17/24 cups total
You purchased a new graphing calculator for the total cost of $103.44, which includes the 10% sales tax.
What was the original price of the calculator?
The original price of the calculator is $94.04
The total cost includes a 10% sales tax on the original cost.
Assume the original cost is denoted by "c" then the correct expression would be:
Total cost = Original price x ( 1 + 10%)
103.44 = c x (1 + 10%)
103.44 = 1.1c
c = 103.44 / 1.1
c = $94.04
Original price was $94.04

If the surface area of a cube is 384, what is the length of one of the sides of
the cube?
Answer:
S = 8
Each side of a face is 8 units.
Step-by-step explanation:
The surface area of the cube is 384 units.
One face of the cube has an area of s^2
A cube has 6 faces
6s^2 = 384 Divide by 6
s^2 = 384 / 6
s^2 = 64 Take the square root of both sides
sqrt(s^2) = sqrt(64)
s = 8
Answer:
8 units
Step-by-step explanation:
Area of 1 side = 384 ÷ 6 = 64 sq units
Length of 1 side = sq.rt. (64) = 8 units Answer

Sam owns a catering business. For any party with up to 200 guests, he charges $ 4000. For each additional guest over 200 he charges $ 15 per person.
Give a formula for the cost in dollars C of having Sam cater your party as a function of p of number of guests over 200.
Linear function is represented by the equation f(x) = mx + b
Where, m = rate of change and b = Initial quantity
Function representing the total amount spent will be P(x) = 15x + 4000
Points to focus upon,
Sam charges fixed charges $4000 for 200 guests.In addition to it $15 per person over 200 guests.Let the number of guests over 200 are 'x'.
Therefore, amount of money spent on 'x' guests = $15x
And the number of guests in the party = 200 + x
Total amount spent on (200 + x) guests = $(4000 + 15x)
If P(x) represents the total amount spent, function for the total expenditure will be,
P(x) = (4000 + 15x)

We're talking about points on the unit circle, which are coordinate pairs (x, y) that satisfy
x² + y² = 1
and the coordinates of point on the circle are governed by
x = cos(t)
y = sin(t)
If t = -35π/6, we have
x = cos(-35π/6) = cos(π/6) = √3/2
and
y = sin(-35π/6) = sin(π/6) = 1/2
because both cosine and sine have a period of 2π, which means
cos(θ) = cos(θ ± 2π) = cos(θ ± 4π) = …
and so on; in particular, we have cos(-35π/6) = cos(π/6) because
-35π/6 = π/6 - 6π
So t = -35π/6 corresponds to the point (√3/2, 1/2).
