Step-by-step explanation:
(a) Filling in the given information will result in two equations in the two unknowns. Dividing one by the other will tell you the value of b.
n=2
1.8 = A₀·b²
n=3
2.4 = A₀·b³
Dividing the second equation by the first gives ...
2.4/1.8 = (A₀·b³)/(A₀·b²) = b
4/3 = b
__
(b) Substituting this into the first equation, we can find A₀.
1.8 = A₀·(4/3)²
1.8(9/16) = A₀ = 1.0125
A₀ is the value of A when n=0. It is the area of the patch at the beginning of observation, before any days passed.
__
(c) The area will be 7 cm when ...
1.0125·(4/3)^n = 7
(4/3)^n = 7/1.0125 . . . . . . . . . . . . divide by A₀
n·log(4/3) = log(7/1.0125) . . . . . . take logarithms
n = log(7/1.0125)/log(4/3) ≈ 6.72092
It will take about 7 days for the area of the patch to exceed 7 cm.
A hair salon uses 4 bottles of shampoo for every 3 bottles of conditioner.
The coordinate plane shows a graph of equivalent ratios.
Use the graph to find the number of bottles of conditioner that are used when 16 bottles of shampoo are used.
Answers
A 3 bottles of conditioner
B 6 bottles of conditioner
C 12 bottles of conditioner
D 20 bottles of conditioner
Answer:
I honestly think it is C.
Step-by-step explanation:
Since "4 bottles of shampoo for every 3 bottles of conditioner" is (4,3), I think the 16 is (16,12) on the graph. It might be worng, might be right. Just go for C.

Ms.sosa's principal gave her $350 to spend on school supplies at the beginning of the year she bought 10 packs of dry erase marker for 9.98 each and 15 pre sharpened pencil that cost 12.99 each how much does she have left to spend
Answer:
I am sooo sorry I really need the points
Step-by-step explanation:
Soooo sorry
Answer:
$55.35
Step-by-step explanation:
10 x 9.98 = 99.80
15 x 12.99 = 194.85
350 - 194.85 = 155.15
155.15 - 99.80 = 55.35
what is the answer to 4x+7=-2+4x
0=(-9)
Step-by-step explanation:
4x + 7 = -2 + 4x
4x + 7 = 4x -2
subtract 7 from both sides of the equation.
simplify your answer.
subtract 4x from both sides of the equation.
simplify your answer again.
4x + 7 = 4x -2
___-7 = 4x -7

Step-by-step explanation:
Tom is told by his doctor that he needs to lose 15 pounds if Tom now it's 285 pounds then by what percentage should Tom's week decrease
Answer:
the percentage is 5.56%
Step-by-step explanation:
The computation of the percentage that the tom should decrease is shown below:
As Doctor said tom to reduce 15 pounds
As of now the tom has 285 pounds
So after considering the 15 pounds, it would be
= 285 - 15
= 270 pounds
Now the percentage that should be considered is
= (285 - 270) ÷ (270)
= 5.56%
Hence, the percentage is 5.56%
Is 301 in the sequence below?
-9, -5,-1,3,7,...
Answer:
no
Step-by-step explanation:
Establish the nth term formula
There is a common difference d between consecutive terms, that is
d = - 5 - (- 9) = - 1 - (- 5) = 3 - (- 1) = 7 - 3 = 4
This indicates the sequence is arithmetic with nth term
[tex]a_{n}[/tex] = a₁ + (n - 1)d
where a₁ is the first term and d the common difference
Here a₁ = - 9 and d = 4 , then
[tex]a_{n}[/tex] = - 9 + 4(n - 1) = - 9 + 4n - 4 = 4n - 13
Equate 4n - 13 to 301
4n - 13 = 301 ( add 13 to both sides )
4n = 314 ( divide both sides by 4 )
n = 78.5
Since n is not an integer then 301 is not in the sequence
301 doesn't belong to the sequence -9, -5,-1,3,7,...
What is A.P sequence?An arithmetic progression or arithmetic sequence is a sequence of numbers such that the difference between the consecutive terms is constant.
The arithmetic sequence is given by a, a + d, a + 2d, a + 3d, … .
Hence, the formula to find the nth term is:
[tex]a_{n}[/tex] = a + (n – 1) × d.
where,
a = first term
d = common difference
n = number of terms
[tex]a_{n}[/tex] = nth term
According to the question
Sequence : -9, -5,-1,3,7,...
First term (a)= -9
common difference (d)= -5 - (-9)
= 4
[tex]a_{n}[/tex] = 301
using the formula of nth term
[tex]a_{n}[/tex] = a + (n-1)d
Substituting the value
301 = -9 + (n-1) 4
310 = (n-1) 4
77.5 = (n-1)
n = 78.5
as n always to be the whole number .
Hence, 301 doesn't belong to the sequence -9, -5,-1,3,7,...

Let X and Y be the following sets: X = {0, 12, 23} Y = {3, 12, 15) Which of the following is the set X/Y?
Answer:
set X/Y = {0,23}
Step-by-step explanation:
We are given the sets;
X = {0, 12, 23}
Y = {3, 12, 15}
Now, we want to find the set X/Y.
The set X/Y means the set that has numbers which are only in set X but not in set Y.
The numbers from inspection of both sets are 0 and 23.
Thus;
set X/Y = {0,23}
