Answer:
1. The total distance will be equal to 20 miles plus the remaining distance which would be obtained when you multiply the speed to time t. The equation would be written as follows:
120 = 20 + 50t
2. The minimum time would be 0 hours. The maximum time is when the total distance of 120 is fully covered.
t ≤ (120 - 20)/50
t ≤ 2 hours
Thus, the domain would be 0 < t ≤ 2.

Answer:
1 First blank; f(1.5)=95 2 Blank; 1.5 3 Blank; 95
Step-by-step explanation:
you use the equation f(x)=50x+20 and put 1.5 in
f(1.5)=50(1.5)+20 = f(1.5)=95
you get 95, and that is the number of miles
1.5 is number of hours
The hotel in the example offer a double room for $20 more than a standard room, before tax. What is the total cost of a double room, including tax? Show your work.
After Assuming a tax percentage of 3.5%, the tax amount gotten is $0.7
and the total cost of a double room, including tax is $20.7
Tax CalculationGiven Data
Cost of double Room = $20Say the Tax is = 3.5%Amount of Tax paid = 3.5/100 * 20
= 0.035* 20
= $0.7
The total cost of a double room, including tax

Hi!
Your answer is "Multiplicative Inverse Property".
We can see that it's multiplying both sides by [tex]\cfrac{5}{4}[/tex] to get [tex]x[/tex] by itself.
This is known as the "multiplicative inverse" because the numerator and the denominator are swapped.
When a number is multiplied by its multiplicative inverse, it equals 1.

Which of the following shows a graph of the equation above?
Answer:
D) Graph Z
Step-by-step explanation:
Convert from point-slope to slope-intercept form
[tex]y-6=4(x-4)\\\\y-6=4x-16\\\\y=4x-10[/tex]
This tells us that the line intersects the y-axis at (0,-10) and that our slope is 4. Therefore, the best choice given the options is D, graph Z.
The linear equation y = 4x - 10 represents the graph z. Then the correct option is D.
What is a linear equation?A connection between a number of variables results in a linear model when a graph is displayed. The variable will have a degree of one.
The linear equation is given as,
y = mx + c
Where m is the slope of the line and c is the y-intercept of the line.
The linear equation is given below.
y - 6 = 4(x - 4)
Convert the equation into slope-intercept form. Then we have
y - 6 = 4(x - 4)
y - 6 = 4x - 16
y = 4x - 16 + 6
y = 4x - 10
The slope of the line is 4 and the y-intercept of the line is negative 10. Then the equation represents the graph z, then option D is correct.

Please help look at the image I need help with number 4. I already did the line plot for number 3 and the data in on the chart. Thank you! :)
Step-by-step explanation:
if you are making double the number of batches, then yout would want to double the # of cups of beans to keep the same recipe.
Since you are doubling the ingredients, all the measurements would change. So yes, the amount of beans that occured most often would change by twice
[tex] \displaystyle \rm \int_{0}^{ \infty } \sum_{n = 0}^{ \infty } \frac{( - 1 {)}^{n} \: {x}^{2n + 1} }{ {2}^{n} \cdot n!} \sum_{n = 0}^{ \infty } \frac{ {x}^{2n} \: dx }{ {2}^{2n} \cdot(n! {)}^{2} } [/tex]
You can check that both series converge for all real x (say, using the ratio test).
Now,
[tex]\displaystyle e^x = \sum_{n=0}^\infty \frac{x^n}{n!} \implies x e^{-x^2/2} = \sum_{n=0}^\infty \frac{(-1)^n x^{2n+1}}{2^n n!}[/tex]
and if you have some familiarity with differential equations, you might recognize that the second series represents a Bessel function, namely
[tex]\displaystyle I_0(x) = \sum_{n=0}^\infty \frac{x^{2n}}{2^{2n} (n!)^2}[/tex]
but we won't bother making use of this.
In the integral, we interchange the integral with the sum
[tex]\displaystyle \int_0^\infty x e^{-x^2/2} \sum_{n=0}^\infty \frac{x^{2n}}{2^{2n} (n!)^2} \, dx = \sum_{n=0}^\infty \frac1{2^{2n} (n!)^2} \int_0^\infty x^{2n+1} e^{-x^2/2} \, dx[/tex]
and consider the sequence of integrals,
[tex]J_n = \displaystyle \int_0^\infty x^{2n} x e^{-x^2/2} \, dx[/tex]
Integrating by parts with
[tex]u = x^{2n} \implies du = 2n x^{2n-1} \, dx[/tex]
[tex]dv = x e^{-x^2/2} \, dx \implies v = -e^{-x^2/2}[/tex]
Then the contribution of uv is 0, so
[tex]J_n = \displaystyle 2n \int_0^\infty x^{2(n-1)} x e^{-x^2/2} \, dx = 2n J_{n-1}[/tex]
We have
[tex]J_0 = \displaystyle \int_0^\infty x e^{-x^2/2} \, dx = 1[/tex]
so that
[tex]J_n = 2n J_{n-1} = 2n (2(n-1)) J_{n-2} = 2n (2(n-1)) (2(n-2)) J_{n-3}[/tex]
and so on; after k steps,
[tex]J_n = 2n (2(n-1)) (2(n-2)) \cdots (2(n-(k-1))) J_{n-k}[/tex]
so that when n = k,
[tex]J_n = 2n (2(n-1)) (2(n-2)) \cdots 2 J_0 = 2^n n![/tex]
Then the integral we want is
[tex]\displaystyle \int_0^\infty x e^{-x^2/2} \sum_{n=0}^\infty \frac{x^{2n}}{2^{2n} (n!)^2} \, dx = \sum_{n=0}^\infty \frac{2^n n!}{2^{2n} (n!)^2} = \sum_{n=0}^\infty \frac1{2^n n!}[/tex]
and knowing the series expansion for [tex]e^x[/tex], it follows that the integral has a value of [tex]e^{1/2} = \boxed{\sqrt{e}}[/tex]

find the slope of the line below. enter your answer as a fraction or a decimal. use a slash mark (/) as the fraction bar if necessary.
Answer:
[tex]m = \frac{4}{3} = 1.3334[/tex]
Step-by-step explanation:
To find the slope of a line, all you have to do is determine 2 points that pass through this line;
for example, in this case,
(-4,-2) (4,4)
Use the equation;
[tex]m = \frac{y2 - y1}{x2 - x1} = \frac{4 - ( - 4)}{4 - ( - 2)} = \frac{4 + 4}{4 + 2} [/tex]
[tex]m = \frac{8}{6} = \frac{4}{3} [/tex]
This line passes through the point (1,0) and that is your y-intercept.
[tex]y = \frac{4}{3} x + 1[/tex]
The requried slope of the given line is m = 3/4.
What is the slope of the line?The slope of the line is defined as the ratio of the rise and run of the straight line on the curve is given as;
m = (y₂ - y₁) / (x₂ - x₁)
Here,
From the graph, we have (-4, -2) and (4, 4).
The slope of the line is given as:
m = (y₂ - y₁) / (x₂ - x₁)
m = (4+2)/(4+4)
m = 6/8
m = 3/4
Thus, the requried slope of the given line is m = 3/4.

Answer:
225 thousand.
Step-by-step explanation:
You are dividing the number in half every time.
Answer:
See Below
Step-by-step explanation:
3,600,000 => 1,800,000 => 900,000 => 450,000 => ?
First, find the pattern.
How would you get from 3,600,000 to 1,800,000?
Lets look at this in a simpler format.
36 => 18
We know that if we divide 36 by 2 we get 18, so divide 3,600,000 by 2.
We get 1,800,000
Now, this might be the pattern. However, before we can say that, we need to test it out with the other #'s. So lets do that.
1,800,000 / 2 = 900,000
900,000 / 2 = 450,000
Great, so we see that this is the pattern: divide by two. Now that we know the pattern, we can continue to find the next number.
450,000 / 2 = ?
450,000 / 2 = 225,000
The next number in the pattern is 225 thousand.

A chocolate company makes chocolate malt balls that are 0.8 inches in diameter. The carton they are to be packed in is approximately a rectangular prism with the dimensions 4 inches by 3 inches by 7.5 inches. How many malt balls will fit in the
Given parameters:
Diameter of the malt balls = 0.8in
Dimensions of the prism = 4in x 3in x 7.5in
Unknown:
Number of malt balls that will fit in the carton = ?
Solution:
To solve this problem, we need to find the volume of each of the malt balls, and then the volume of the rectangular prism.
Volume of the malt balls = [tex]\frac{4}{3} \pi r^{3}[/tex]
This is because we assume that the balls have a spherical shape.
Where r is radius and π is a constant
Radius of the malt balls = [tex]\frac{0.8}{2}[/tex] = 0.4in
So, volume = [tex]\frac{4}{3} x 3.142 x 0.4^{3}[/tex] = 0.27in³
Volume of the rectangular prism = l x w x h
where l is the length
w is the width
h is the height
So the volume is 4 x 3 x 7.5 = 90in³
The number of malt balls that can be packed here = [tex]\frac{90}{0.27}[/tex] = 333 malt balls
