According to the solving Sam will spend $585.00 of the money he collects on cleaning materials.
What do the percentages mean?%, a relative figure signifying hundredths of any amount. Since one percent (symbolised as 1%) is equal to one hundredth of something, 100 percent stands for everything, and 200 percent refers to twice the amount specified. percentage. Mathematical percentile is a related topic.
According to the given information:Sam collects $150.00 each day for 6 days, so the total amount he collects is:
$150.00/day x 6 days = $900.00
The shelter will use 35% of the money he collects to buy pet food. To find out how much money will be used to buy pet food, we can multiply the total amount Sam collects by 35% (or 0.35):
$900.00 x 0.35 = $315.00
So, $315.00 of the money that Sam collects will be used to buy pet food. To find out how much money will be used to buy cleaning supplies, we can subtract the amount used to buy pet food from the total amount collected:
$900.00 - $315.00 = $585.00
$585.00 of the money that Sam collects will be used to buy cleaning supplies.

The linear model would be a reasonable way to predict the temperature as temperature determines the number of ice cream that would be sold.
What is temperature?Temperature is a unit of hotness and coldness that can be described in terms of any number of arbitrary scales. It also represents the direction wherein heat energy will naturally flow, from either a hotter (i.e., higher temperature) body to a colder body.
Temperature is not the same as the energy of such a thermodynamic system; for instance, an iceberg has a significantly larger total heat energy than a match, despite the fact that a match is burning at a significantly higher temperature. The linear model would be a reasonable way to predict the temperature as temperature determines the number of ice cream that would be sold.

A beetle is 1/5 inch wide and 2/5 inch long.How much greater is the beetle’s length than it’s width?
Answer: To find how much greater the beetle's length is than its width, we need to subtract the width from the length:
Length - Width
Substituting the given values, we get:
2/5 inch - 1/5 inch
Simplifying the expression by finding the common denominator of 5, we get:
(2/5 - 1/5) inch
= 1/5 inch
Therefore, the beetle's length is 1/5 inch greater than its width.

If f(x) is an exponential function where f(-1) = 30 and f(4) = 85, then find the value of f(3), to the nearest hundredth.
========================================================
Work Shown:
The notation f(-1) = 30 tells us that (x,y) = (-1,30) is a point on the exponential curve.
Plug in x = -1 and y = 30 and solve for 'a'
y = a*b^x
30 = a*b^(-1)
30 = a*(1/b^1)
30 = a/b
a = 30b
--------------------------------------------------
Now plug that into the equation to get
y = a*b^x
y = 30b*b^x
y = 30b^1*b^x
y = 30b^(1+x)
Afterward, plug in x = 4 and y = 85 to solve for b.
85 = 30b^(1+4)
85 = 30b^5
b^5 = 85/30
b = (85/30)^(1/5)
b = 1.23157122757057
We can then determine the value of 'a'
a = 30b
a = 30*1.23157122757057
a = 36.947136827117
--------------------------------------------------
To summarize,
a = 36.947136827117b = 1.23157122757057both of which are approximate.
Since we want f(3) to the nearest hundredth, we don't really need to go too overboard with precision. Let's round 'a' and b to 4 decimal places.
We then get
a = 36.9471b = 1.2316This means
y = a*b^x
turns into
y = 36.9471*(1.2316)^x
As a check, plug in x = -1 to get y = 29.999269; we'll have rounding error since we rounded those 'a' and b values earlier. But when rounding 29.999269 to the nearest hundredth, we get y = 30.
Also, plug x = 4 into the equation to get y = 85.00785875 which rounds to 85.
--------------------------------------------------
The last step is to plug x = 3 into the equation
y = 36.9471*(1.2316)^x
y = 36.9471*(1.2316)^3
y = 69.0222951885528
y = 69.02 which is the final answer
--------------------------------------------------
If you were to use those more accurate values of 'a' and b, then x = 3 would lead to y = 69.0175266335801; that rounds to 69.02 when rounding to the nearest hundredth (aka 2 decimal places). So this shows we can stick with the less accurate 'a' and b values while still getting the correct final answer.
GeoGebra and Desmos are great tools to help quickly verify the answer.
Answer:
f(3) = 69.02 (nearest hundredth)
Step-by-step explanation:
Exponential FunctionAn exponential function is used to calculate the exponential growth or decay of a given set of data. In an exponential function, the variable is the exponent.
[tex]\boxed{\begin{minipage}{9 cm}\underline{General form of an Exponential Function}\\\\$y=ab^x$\\\\where:\\\phantom{ww}$\bullet$ $a$ is the initial value ($y$-intercept). \\ \phantom{ww}$\bullet$ $b$ is the base (growth/decay factor) in decimal form.\\\end{minipage}}[/tex]
Given:
f(-1) = 30f(4) = 85Substitute these values into the general form of an exponential function to create two equations in terms of a and b:
[tex]\begin{aligned}\implies f(-1)&=30\\ab^{-1}&=30\end{aligned}[/tex]
[tex]\begin{aligned}\implies f(4)&=85\\ab^{4}&=85\end{aligned}[/tex]
Divide the second equation by the first equation to eliminate a:
[tex]\begin{aligned}\implies \dfrac{ab^4}{ab^{-1}}&=\dfrac{85}{30}\\\\\dfrac{b^4}{b^{-1}}&=\dfrac{85}{30}\\\\\end{aligned}[/tex]
Solve for b:
[tex]\begin{aligned}\implies \dfrac{b^4}{b^{-1}}&=\dfrac{85}{30}\\\\b^{4-(-1)}&=\dfrac{17}{6}\\\\b^{5}&=\dfrac{17}{6}\\\\b&=\sqrt[5]{\dfrac{17}{6}}\end{aligned}[/tex]
Substitute the found value of b into ab⁴ = 85:
[tex]\implies a\left(\sqrt[5]{\dfrac{17}{6}}\right)^4=85[/tex]
Solve for a:
[tex]\implies a=\dfrac{85}{\left(\sqrt[5]{\dfrac{17}{6}}\right)^4}[/tex]
[tex]\implies a=\dfrac{85}{\sqrt[5]{\dfrac{17^4}{6^4}}}[/tex]
[tex]\implies a=\dfrac{85}{\sqrt[5]{\dfrac{83521}{1296}}}[/tex]
Substitute the found values of a and b into the exponential function formula to create an exponential equation for the given parameters:
[tex]f(x)=\left(\dfrac{85}{\sqrt[5]{\dfrac{83521}{1296}}}\right)\cdot \left(\sqrt[5]{\dfrac{17}{6}}\right)^x[/tex]
To find the value of f(3), substitute x = 3 into the equation:
[tex]\begin{aligned}\implies f(3)&=\left(\dfrac{85}{\sqrt[5]{\dfrac{83521}{1296}}}\right)\cdot \left(\sqrt[5]{\dfrac{17}{6}}\right)^3\\\\&=69.0175266...\\\\&=69.02\; \;\sf (nearest\;hundredth)\end{aligned}[/tex]
Therefore, the value of f(3) to the nearest hundredth is 69.02.

A) {68, 116, 164, 212, 260, 308, 356, 404}
B) all integers from 1 to 8 inclusive
C) all real numbers from 1 to 8 inclusive
D) all real numbers
Answer:
The practical domain of the function is the set of integers from 0 to 8, inclusive, which is option B.
Step-by-step explanation:
The practical domain of the function is limited by the given constraints: Joe can purchase up to 8 boxes of hot dogs, and he cannot purchase partial boxes. Therefore, the number of boxes he can purchase is a whole number between 0 and 8, inclusive.
Substituting the values from 0 to 8 into the function, we get:
f(0) = 48(0) + 20 = 20
f(1) = 48(1) + 20 = 68
f(2) = 48(2) + 20 = 116
f(3) = 48(3) + 20 = 164
f(4) = 48(4) + 20 = 212
f(5) = 48(5) + 20 = 260
f(6) = 48(6) + 20 = 308
f(7) = 48(7) + 20 = 356
f(8) = 48(8) + 20 = 404
Therefore, the practical domain of the function is the set of integers from 0 to 8, inclusive, which is option B.

What is Number Line?In math, a number line can be defined as a straight line with numbers arranged at equal segments or intervals throughout. A number line is typically shown horizontally and can be extended indefinitely in any direction.
To show the numbers between 10 and 20 that have a remainder of 2 when divided by 3, we need to start with the first number in that range that has a remainder of 2 when divided by 3, which is 11. Then, we can add 3 to that number to get the next number that has a remainder of 2 when divided by 3, which is 14.
We can continue adding 3 to each previous number to get the rest of the numbers that meet this condition:
11, 14, 17, 20

Vehicle manufactures crash test their new vehicles and measure the impact force Subaru's Crosstrek impact force measurements are normally distributed with a mean of 30 metric tons and a standard deviation of 2 metric tons. Suppose Subaru tests a random sample of 9 cars and calculates the sample mean impact force.
a. What is the mean and standard deviation of the sampling distribution of the sample mean impact force?
b. What is the probability of a sample mean impact force being less than 28.7 metric tons?
The standard deviation is 0.67 metric tonnes, and the mean of the sampling distribution of the sample mean impact force is 30 metric tonnes.
What is the mean and standard deviation of the sampling distribution of the sample mean impact force?
a. The following formulas can be used to determine the mean and standard deviation of the sampling distribution of the sample mean impact force:
30 metric tonnes are the population's mean and the sampling distribution's mean.
Standard deviation of the sample distribution is equal to the square root of the population's standard deviation.
= [tex]2 / sqrt(9) (9)[/tex]
= 0.67 tonnes in metric
As a result, the standard deviation is 0.67 metric tonnes, and the mean of the sampling distribution of the sample mean impact force is 30 metric tonnes.
What is the probability of a sample mean impact force being less than 28.7 metric tons?
b. Using the z-score calculation and common normal distribution tables, we can determine the likelihood that the sample mean impact force will be less than 28.7 metric tonnes. The z-score equation is:
(Sample Mean - Population Mean) = Z (standard deviation of sampling distribution)
= (28.7 - 30) / 0.67 = -2
We discover that the probability of a z-score less than -2 is 0.0228 using the usual normal distribution table. Consequently, 0.0228 or 2.28% of the time, the sample mean impact force will be less than 28.7 metric tonnes.

A function describes the relationships between different components that all lead to the same result. A function is made up of several variable distinct components that, when placed together, produce specific outputs for every input.
Here,
The starting height (h0) is 4 feet, and the initial speed (v0) is 75 feet per second.
The ball's vertical movement is modelled by the formula h(t) = 16t2 + v0t + h0.
When we change the numbers, we obtain:
h(t) = −16t2 + 75t + 4
The vertex of the parabolic function marks the height of the spheroid at its greatest height.
The vertex's t-value is determined by:
t = −v0/2a
where a represents the t2 component in the h-function (t).
When we change the numbers, we obtain:
t = −75/(2(−16)) = 2.34375
2.34375 seconds pass after the ball is thrown before it hits its highest point.
Given is the utmost height:
h(2.34375) = −16(2.34375) (2.34375)

g(n)=−50−15n. complete the recursive formula of g(n).
Answer: To complete the recursive formula for g(n) = -50 - 15n, we need to find an expression for g(n) in terms of previous terms of the sequence.
One way to do this is to notice that g(n) can be obtained by subtracting 15 from the previous term, g(n-1):
g(n) = -50 - 15n
= -50 - 15(n-1) - 15 (adding and subtracting 15)
= g(n-1) - 15
Therefore, the recursive formula for g(n) is:
g(0) = -50 (base case)
g(n) = g(n-1) - 15 (recursive step)
This means that to find g(n), we need to first find g(n-1) and then subtract 15 from it. We can use this recursive formula to generate any term in the sequence of g(n).
