Answer:
The map is displaying 600 miles of land.
Step-by-step explanation:
To find the number of miles of land being displayed on the map, you need to multiply the length of the map in inches by the conversion factor, which is the ratio of inches to miles. In this case, the conversion factor is 2 inches per 200 miles.
So, to find the number of miles of land being displayed on the map, you would do the following calculation: 12 inches * (200 miles / 2 inches) = 600 miles.

the ratio of the short side of a certain rectangle to the long side is equal to the ratio of the long side to the diagonal. what is the square of the ratio of the short side to the long side of this rectangle?
As per the Pythagoras theorem, the ratio of the short side to the long side of this rectangle is (√5 - 1)/ 2
In math Pythagoras theorem is defined as the sum of the squares on the legs of a right triangle is equal to the square on the hypotenuse
Here we have given that the ratio of the short side of a certain rectangle to the long side is equal to the ratio of the long side to the diagonal.
And we need to find is the square of the ratio of the short side to the long side of this rectangle
While we looking into the given question we have identified that the short side of the rectangle be a and let the long side of the rectangle be b.
Therefore, the diagonal, according to the Pythagorean Theorem, is
√(a²+b²)
Now we can write the equation:
a / b = b /√ a² + b²
Then we have to find the square of the ratio of a to b.
Let us consider the answer, be k.
When we squaring the above equation,
a²/ b² = b² / a² + b² = k
When we solve this one then we get the value of k = 1.
Now we have to Multiply each side of the equation by k,
=> k² = 1 - k.
And then adding each side by k,
k² + k − 1 = 0.
Now, we have to Solving for k using the Quadratic Formula,
= > k = -1 ± √[1² − 4(1)(−1)] / 2
=> k = -1±√5/2
As we know that the ratio of lengths and diagonals of a rectangle cannot be negative.
Therefore, the resulting value is √5 - 1/2

Suppose IQ scores were obtained for 20 randomly selected sets of twins. The 20 pairs of measurements yield x=98.13, y=100.6, r=0.904, P-value=0.000, ŷ=14.68+0.88x, where x represents the IQ score of the twin born first. Find the best predicted value of ModifyingAbove y with caret given that the twin born first has an IQ of 104? Use a significance level of 0.05.
The predicted value of the twin born first has an IQ of 104 is 106.2..
We have given that,
sample size n = 10
x = 98.13
y = 100.6
r = 0.904
p-value = 0.000
y'= 14.68 + 0.88x
significance level = 0.05
and we have to find predicted value of the twin born first has an IQ of 104.
We know that x represents the IQ score of the twin born first.
Therefore value of x is 104.
Hence the predicted value P will be,
P = 14.68 + 0.88(104)
= 14.68 + 91.52
P = 106.2
Therefore the best predicted value of the twin born first has an IQ of 104 is 106.2.

The general solution of the given differential equation is y = (2x[tex] {e}^{(xy)} [/tex] × (x+1) + [tex] {2x}^{ {2e}^{(xy)} } [/tex] + C) / (x+1)(x+2) and the largest interval is (-infinity, -2) U (-1, infinity).
The general solution of the mentioned differential equation will be calculated as follows -
Firstly rewriting the differential equation in standard form:
(x+1) dy/dx + (x+2)y = 2x[tex] {e}^{(xy)} [/tex]
Calculating the integrating factor to make the LHS as a total derivative:
As known, formula for integrating factor is:
mu = [tex] {e}^{(integral of (x+2)/(x+1) dx)} [/tex]
= [tex] {e}^{(ln(x+1) + ln(x+2))} [/tex]
= (x+1)(x+2)
Now multiplying both sides of the equation by the integrating factor:
(x+1)(x+2) × (x+1) dy/dx + (x+1)(x+2) × (x+2)y = 2x[tex] {e}^{(xy)} [/tex] × (x+1)(x+2)
LHS will be a total derivative. Rearrange the equation for the same -
d/dx((x+1)(x+2)y) = 2x[tex] {e}^{(xy)} [/tex] × (x+1)(x+2)
Integrating both sides of the equation:
(x+1)(x+2)y = integral of 2x[tex] {e}^{(xy)} [/tex] × (x+1)(x+2) dx
= 2x[tex] {e}^{(xy)} [/tex] × (x+1) + [tex] {2x}^{ {2e}^{(xy)} } [/tex] + C
Now find the equation for y:
y = (2x[tex] {e}^{(xy)} [/tex] × (x+1) + [tex] {2x}^{ {2e}^{(xy)} } [/tex] + C) / (x+1)(x+2)
Equation for y is the general solution of the differential equation where constant C is the arbitrary constant of integration.

Can someone please help me to convert 2,8hours to hours, minutes and seconds ?
convert 2.8hours to hours, minutes and seconds is 2.8 hours = 2 hours 48 minutes 0 seconds
The conversion of 2.8 hours into hours, minutes and seconds is relatively simple. To begin, we must first convert 2.8 hours into minutes. To do this, we multiply 2.8 by 60, which equals 168 minutes. Now, we need to convert those minutes into hours and seconds. To do this, we divide the 168 minutes by 60, which gives us 2 hours. We then take the remainder, which is 48 minutes, and divide it by 60, which gives us 0 seconds. Therefore, 2.8 hours is equivalent to 2 hours 48 minutes 0 seconds.

Answer:
3753.20 ft
Step-by-step explanation:
tan 80° = 3400 ft/x
x = 599.51 ft = distance at ground level from point directly below mountain peek to edge of mountain.
599.51 ft + 990 ft = 1589.51 ft = horizontal distance at ground level from where cable is attached to the ground to the center of the mountain. This is a leg of a right triangle.
3400 ft is another leg of a right triangle.
(1589.51 ft)² + (3400 ft)² = y²
The hypotenuse, y, is the length of the cable.
y = 3753.20 ft

What is slope of a line?
A line's slope in mathematics is defined as the ratio of the change in the y coordinate to the change in the x coordinate.
Both the net change in the y-coordinate and the net change in the x-coordinate are denoted by y and x, respectively.
Consequently, the formula for the change in y-coordinate with respect to the change in x-coordinate is
m = y/x = y/x = change in y/change in x
where "m" represents a line's slope.
Additionally, the slope of the line can be shown as
tan θ = Δy/Δx
So, the slope of a line is tan.
When the equation is written in the slope-intercept form (y=mx+b) we can find the y-intercept by looking at the equation. The value of b is the y-intercept. This is because the y-intercept is when the x value equals 0. When x = 0, mx = 0, so when x = 0, y = b.
To find the x-intercept we set y = 0 and solve the equation for x. This is because when y=0 the line crosses the x-axis.
When an equation is not in y = mx + b form, we can solve for the intercepts by plugging in 0 as needed and solving for the remaining variable.
To find y-intercept: set x = 0 and solve for y. The point will be (0, y).
To find x-intercept: set y = 0 and solve for x. The point will be (x, 0).

2,092.1 is the population of the town after 5 years, and P(t)=2500*(1-0.035)^t is the exponential function.
What is the exponential decay function?In mathematics, exponential decay defines the process of diminishing an amount by a consistent percentage rate over a period of time.
It can be stated by the formula y=a(1-b)x wherein y is the total form and is the initial money, b is the decay factor, and x is the quantity of time that has passed.
So, we got:
r = 3.5%/100% = 0.035
We have our exponential function:
P(t) = 2500*(1 - 0.035)^t
The number after 5 years is provided by substituting t = 5, we will get:
P(5) = 2500*(1 - 0.035)^5 = 2,092.1

The function f(x) = −16x² + 48x + 64 represents the height of an object above the ground in feet, x seconds after being launched.
How to find f(-1)?To find f(-1), we plug -1 into the function:
f(-1) = −16(-1)² + 48(-1) + 64
= 16 - 48 + 64
= 32
This means that 1 second after the object was launched, it was 32 feet above the ground.
To find f(0.5), we plug 0.5 into the function:
f(0.5) = −16(0.5)² + 48(0.5) + 64
= −16(0.25) + 24 + 64
= −4 + 24 + 64
= 84
This means that 0.5 seconds after the object was launched, it was 84 feet above the ground.
Since the function represents the height of the object above the ground, the domain of the function would be the set of all real numbers x such that x represents the number of seconds after the object was launched.
This would include all positive and negative values of x, since the object could have been launched at any time in the past or future. However, if the problem specifies a specific range of time, then the domain would be limited to that range.
Therefore, the correct answer is as given above
