Consider the following table that describes the mass of a kitten as weeks go by. If you know the kitten grows by 10% each week for the first 5 weeks, fill in the table for the values each week. Week Mass (grams) (start) 80
Answer:
Week Mass (gram)
(start) 80
1 88
2 96.8
3 106.48
4 117.128
Step-by-step explanation:
From the question we are told that
The mass of the kitten at the start week is m = 80 g
The rate at which the kitten grows is r = 0.10
Generally the mass of the kitten at the first week is mathematically represented as
[tex]m_1 = ( r * m) + m[/tex]
=>[tex]m_1 = ( 0.10 * 80 ) + 80 [/tex]
=>[tex]m_1 = 88 \ g [/tex]
Generally the mass of the kitten at the second week is mathematically represented as
[tex]m_2 = ( r * m_1) + m_1[/tex]
=>[tex]m_2 = ( 0.10 * 88 ) + 88 [/tex]
=>[tex]m_2 = 96.8 \ g [/tex]
Generally the mass of the kitten at the third week is mathematically represented as
[tex]m_3 = ( r * m_2) + m_2[/tex]
=>[tex]m_3 = ( 0.10 * 96.8) + 96.8 [/tex]
=>[tex]m_3 = 106.48 \ g [/tex]
Generally the mass of the kitten at the fourth week is mathematically represented as
[tex]m_4 = ( r * m_3) + m_2[/tex]
=>[tex]m_4 = ( 0.10 * 106.48) + 106.48 [/tex]
=>[tex]m_4 = 117.128 \ g [/tex]
Week Mass (gram)
(start) 80
1 88
2 96.8
3 106.48
4 117.128

in a mixture a there is 2l of syrup in 3l of water. in a mixture b there is 1.8l of syrup in 2.5 water. in which mixture, concentration syrup is higher?
Answer:
Step-by-step explanation:
In the first mixture the concentration syrup is higher
Concentration syrup is higher in mixture B.
What is Proportion?Two or more ratios made to be equal to each other is termed as proportion.
We have to use the proportional concept here by finding the concentration of syrup in 1 l of water.
Mixture A:
Concentration of syrup in 3 l of water = 2 l
Concentration of syrup in 1 l of water = 2/3 l = 0.67 l
Mixture B :
Concentration of syrup in 2.5 l of water = 1.8 l
Concentration of syrup in 1 l of water = 1.8 / 2.5 = 0.72 l
Concentration of syrup in mixture A in 1 liter of water is less than the concentration of syrup in mixture B in 1 liter of water.
Hence the concentration of syrup in mixture B is higher because concentration of syrup in mixture B in 1 liter of water is higher than the concentration of syrup in mixture A in 1 liter of water.

Selecting a State Choose one of the 50 states at
random.
a. What is the probability that it begins with M?
b. What is the probability that it doesn't begin with a
vowel?
Answer:
PART ONE- 8/50 PART 2-38/50
Step-by-step explanation:
First of all, we know that there are 50 states. Lets see how many states begins with M first.
Maine (27 C, 5 P)
Maryland (28 C, 5 P)
Massachusetts (29 C, 4 P)
Michigan (28 C, 4 P)
Minnesota (28 C, 2 P)
Mississippi (27 C, 6 P)
Missouri (25 C, 3 P)
Montana (27 C, 6 P)
There are 8 states which means that the probabilty is 8/50 which simplifies to 4/25
We know that 12 states begins with a vowel. 50-12 is 38/50
The probability that it begins with M is 0.16 and the probability that it doesn't begin with a vowel is 0.76
What is probability?Probability is the branch of mathematics concerning numerical descriptions of how likely an event is to occur.
Given that, Selecting a State, Choose one of the 50 states at random.
We know that, P(A) = n(A)/n(S)
where, P(A) is the probability of an event “A” n(A) is the number of favourable outcomes. n(S) is the total number of events in the sample space.
a) There are 8 states which begins with M, that means the probability = 8/50 = 4/25 = 0.16
b) We know that 12 states begins with a vowel,
Therefore, the probability that it doesn't begin with a vowel = 1 - 12/50 = 38/50 = 0.76
Hence, The probability that it begins with M is 0.16 and the probability that it doesn't begin with a vowel is 0.76

The figure shows a pair of parallel line segments on a coordinate grid: the line segments are translated 2 units to the left to form J’K and M’N. Which statement describes J’K and M’N
Answer:
J
Step-by-step explanation:
Answer:
Line segments J'K' and M'N' do not intersect and are the same distance apart as JK and MN.
Step-by-step explanation:
If the line segments are translated 2 units to the left, then JK will start at (1, -1) and go to (5, -1), and MN will start at (1, -2) and to to (5, -2). So the line segments remain parallel and the same distance apart.

Find f(−9)
Answer:
f(-9)= -189
Step-by-step explanation:
f(-9)= -3(-9)^2-6(-9)
f(-9)= -3(-9)^2 +54
f(-9)= -3(81) +54
f(-9)= -243 + 54
f(-9)= -189
[tex]f(-9)[/tex] is [tex]-189[/tex]
What is function?
In mathematics, a function from a set X to a set Y assigns to each element of X exactly one element of Y. The set X is called the domain of the function and the set Y is called the codomain of the function. Functions were originally the idealization of how a varying quantity depends on another quantity.
According to question, we have the function [tex]f(x)=-3x^2-6x[/tex]
We have to find [tex]f(-9)[/tex]
So, [tex]f(-9)=-3[/tex]×[tex](-9)^{2}[/tex][tex]-6(-9)[/tex]
[tex]=-243+54[/tex]
[tex]=-189[/tex]
Hence, we can conclude that [tex]f(-9)[/tex] is [tex]-189[/tex]

Write the equation of the line containing point (-3, 2) and having a slope of 6.
Answer:
y + 2 = 6(x - 3)
Step-by-step explanation:
Point-Slope Form: y + y₁ = m(x + x₁)
Simply plug in your known variables into the point-slope form to find your equation:
y₁ = 2
x₁ = -3
m = 6
y + 2 = 6(x - 3)
Let f(x) = 6x^2 +5 and g(x) = 3x - 5. Find g(f(0)).
Answer:
The answer is 10.
Step-by-step explanation:
f(x) = 6* x^2 + 5
f(0) = 6*0^2 + 5 = 5
g(x) = 3x - 5
g(f(x)) = 3 * (f(x)) - 5
g(f(0)) = 3 * 5 - 5 = 10
