Answer:
C5
Step-by-step explanation: 10 x 2 = 20 so you add the 2 to the other one and get 4. Then half of 10 is 5 and half of 2 is 1, so add 1 to 4 and your answer is 5.
10x2= 20 +5= 25 Answer:5
Martin ran 6.5 miles in one hour. At that speed, how many miles will he
three hours?
Answer:
19.5 miles
Step-by-step explanation:
6.5 mph means that each hour, he runs 6.5 miles.
So you already know how much he runs per hour.
6.5 mph x 3 h = 19.5mi
Who know this answer
x=12,y=12√3
sin60=y/24
√3/2×24=y
y=12√3
again
24^2=x^2+y^2
576=x²+12×12×3
x²=576-432
x=√144
x=12

g Suppose that the populationy(t)of a certain kind of fish is given by the logistic modely′= 3y−2y2(a) Solve the Bernoulli equation. (Must be done using Bernoulli’s Equation method)(b) Suppose fish are added to the pond at a constant rate of 2 (Basically add 2 to your equation).Set up the Riccati equation, find a particular solution by inspection (it should be obvious if youlook for a constantyfunction), and then solve the equation.
Answer:
y = [tex]\frac{3}{2 + 3Ce^{-3t} }[/tex]
Step-by-step explanation:
As given , y' = 3y - 2y²
⇒y' - 3y = -2y²
Divide by y² in the above equation
⇒[tex]\frac{y'}{y^{2} } - \frac{3y}{y^{2} } = -\frac{2y^{2} }{y^{2} }[/tex]
⇒[tex]\frac{y'}{y^{2} } - \frac{3}{y } = -2[/tex] ........(1)
Now , let [tex]\frac{1}{y}[/tex] = u
⇒-[tex]\frac{1}{y^{2} } \frac{dy}{dt} = \frac{du}{dt}[/tex]
⇒-[tex]\frac{1}{y^{2} }y' = \frac{du}{dt}[/tex]
∴ equation (1) becomes
-[tex]\frac{du}{dt}[/tex] - 3u = -2
⇒[tex]\frac{du}{dt}[/tex] + 3u = 2
It is a linear differential equation
Now,
Integrating factor = I.F = [tex]e^{\int\limits {3} \, dt }[/tex] = [tex]e^{3t}[/tex]
∴ The solution becomes
u.(I.F) = [tex]\int\limits {2.(I.F)} \, dt[/tex] + C
⇒u.([tex]e^{3t}[/tex]) = [tex]\int\limits {2.(e^{3t} )} \, dt[/tex] + C
⇒u.([tex]e^{3t}[/tex]) = [tex]\frac{2e^{3t} }{3}[/tex] + C
⇒u = [tex]\frac{2}{3} + Ce^{-3t}[/tex]
As [tex]\frac{1}{y}[/tex] = u
⇒[tex]\frac{1}{y}[/tex] = [tex]\frac{2}{3} + Ce^{-3t}[/tex]
⇒ y = [tex]\frac{1}{\frac{2}{3} + Ce^{-3t} } = \frac{3}{2 + 3Ce^{-3t} }[/tex]
⇒ y = [tex]\frac{3}{2 + 3Ce^{-3t} }[/tex]

Find the length of side x in simplest radical form with a rational denominator.
Answer:
X = 4
Step-by-step explanation:
That traingle is an isosceles triangle. You know this because the base angles, 45 and 45 are the same. Another characteristic of an iscosceles traingle is that the base sides ( in this case 4 and X ) are always the same

Write an equation of the line in slope-intercept form.
Answer:
y = 2x+3
Step-by-step explanation:
You can see that the line crosses the y-axis at (0,3), so the y-intercept is 3.
To find the slope, compare the coordinates of the two points marked on the line, (0,3) and (-3,-3).
slope = Δy/Δx = ((-3)-3)/((-3)-0) = (-6)/(-3) = 2
Slope-intercept equation for line of slope 2 and y-intercept 3:
y = 2x+3

Consider the equation r = 5 sin(theta). Use the drop-down boxes to complete the sentences.
The graph is a
The graph is symmetric with respect to the polar axis
The greatest distance between any two points on the graph is 5 units.
9514 1404 393
Answer:
circley-axis5 unitsStep-by-step explanation:
It can be helpful to actually see the graph. For 0 ≤ θ ≤ π, a circle is developed above the x-axis, symmetrical about the y-axis (θ=π/2). For π ≤ θ ≤ 2π, the same circle is traced again in the same direction (CCW), as values of r are negative for those angles.
The circle has a radius of 2.5, centered at (0, 2.5), so the diameter is 5 units. The length of the diameter is the farthest distance between any two points on a circle.

Help please!! Thanks
Answer:
Q2 2010
Step-by-step explanation:
Let the number of quarters = x
Samsung increases by 6 each quarter.
Apple decreases by 1 each quarter.
Samsung
L = a + (x - 1)*6
a = 1
L = 1 + (x - 1)*6
Apple
L = a - (x - 1)*1
a = 53
L = 53 - (x - 1)*1
Now the problem is how many quarters go by until they meet?
1 + (x - 1)*6 = 53 - (x - 1) Remove the brackets
1 + 6x - 6 = 53 - x + 1 Combine like terms on both sides.
-5 + 6x = 54 - x Add 5 to both sides
6x = 59 - x Add x to both sides
7x = 59
x = 59/7 = 8 3/7
So sometime in the 8th quarter from zero they will be equal. At the end of the quarter, Samsung will be greater than Apple
So the answer should be 4 quarters from Q2 2009 or Q2 2010

It is a little unclear when you state the problem what exactly is going on with that fraction. This is a common issue when you try to type up equations. On the right side, you have a fraction bar and then a bunch of stuff after it. We need to clear up what is supposed to be in the numerator and what is supposed to stay in the denominator. This is important not just for typing up questions on the internet to get help but in using your calculator as well. If what the equation means is that both "f" and "q+z" are in the denominator, but then on your calculator you type something 1 / 2 * f * ( q + z ), most calculators (e.g. TI 83/84 and almost any basic or scientific model) will interpret that as meaning only the 2 is on the bottom and the rest is on top.
If you meant the f and the q+z are on top, then Steve's answer is good.
If you meant the f and the q+z are supposed to be on the bottom, then we have a little bit different process.
First, write down the operations that are happening to q, and in what order they happen from inside out, that is, according to the regular PEMDAS rule:
1. z is added
2. 2f is multiplied
3. The result is divided into 1 (as opposed to being divided by 1).
So, to solve for q, we "invert" the order of operations and do the inverse operation of our 3 steps, and also in reverse order.
1. To get the big thing out of the denominator (Step 3), we will multiply both sides by 2f(q+z). Now we have:
C*2f(q+z) = 1, or as we normally write it,
2Cf(q+z) = 1
2. Now we have to adjust our steps just a little bit because we have the *C part too. So we will change Step 2 above to "2Cf is multiplied." We invert that by dividing, so we have:
q+z = 1/[2Cf]. Notice how I put brackets around the entire denominator so it's clear!
3. Finally to invert Step 1 we subtract z:
q = 1/[2Cf] - z

A Bloomberg BusinessWeek North American subscriber study collected data from a sample of 2861 subscribers. Fifty-nine percent of the respondents indicated an annual income of $75,000 or more, and 50% reported having an American Express credit card.
1.What is the population of interest in this study?
2.Is annual income a qualitative or quantitative variable?
3.Is ownership of an American Express card a qualitative or quantitative variable?
4.Does this study involve cross-sectional or time series data?
5. Determine whether the following two statistical inferences may be made based on the sample data collected.
An estimated 59% of the population of subscribers has an annual income of $75,000 or more.
An estimated 60% of the population of subscribers has an American Express credit card.
Answer:
Bloomberg Business week NorthAmerica Subscribers
; Quantitative ; Qualitative ; No ; Yes ; No
Step-by-step explanation:
Sample size = 2861
Percentage respondent with annual income ≥ 75000 = 59%
Percentage having an American Express credit card
1.What is the population of interest in this study?
Bloomberg business week NorthAmerica Subscribers
2. Quantitative
Annual income is quantitative because it is numeric, that is repress red by numbers which can be used to perform sensible numerical computation such as additions, mean, multiplication and so on.
3.Qualitative
No ; ownership of an American express card is a Qualitative variable as it will take responses as (yes or no), even when represented or coded as numbers, it will make no numerical sense to peform mathematical calculations with it.
4.
No ; time series data has to do with data collected with respect to a particular month, year or seasonal data.
5. Determine whether the following two statistical inferences may be made based on the sample data collected.
An estimated 59% of the population of subscribers has an annual income of $75,000 or more.
Yes ;
An estimated 60% of the population of subscribers has an American Express credit card.
No ; the research says 50% and not 60%
