An airplane is descending in preparation for a landing at an airport. The height, h, in meters of the airplane above the ground level of the airport is a linear function of time, t, where t is the number of minutes
after the plane started to descend. The plane was 3,915 meters above the ground level of the airport 2 minutes into the plane's decent and was 2,025 meters above after 9 minutes. How long will it take the
plane to land at the airport after it started to descend? (1 point)
O 16 minutes
O 7.5 minutes
16.5 minutes
14.5 minutes

Answer:

[tex]8 \le f(4) - f(2) \le 10[/tex]

Step-by-step explanation:

Given

[tex]4 \le f'(x) \le 5[/tex]

Required

Determine the minimum and maximum value of f(4) - f(2)

This question will be answered using the following mean value theorem.

[tex]f'(x) = \frac{f(b) - f(a)}{b - a}[/tex]

In this case: [tex]b = 4[/tex] and [tex]a = 2[/tex]

So, we have:

[tex]f'(x) = \frac{f(4) - f(2)}{4 - 2}[/tex]

[tex]f'(x) = \frac{f(4) - f(2)}{2}[/tex]

Make f(4) - f(2), the subject:

[tex]f(4) -f(2) = 2 * f'(x)[/tex]

From the given range: [tex]4 \le f'(x) \le 5[/tex]

We have that; f'(x) is at minimum at 4

So, the minimum of f(4) - f(2) is:

[tex]f(4) -f(2) = 2 * 4[/tex]

[tex]f(4) -f(2) = 8[/tex]

We have that; f'(x) is at maximum at 5

So, the maximum of f(4) - f(2) is:

[tex]f(4) - f(2) = 2 * 5[/tex]

[tex]f(4) - f(2) = 10[/tex]

Hence, the minimum and maximum values can be expressed as:

[tex]8 \le f(4) - f(2) \le 10[/tex]

Answer:

0.86 (Approx)

Step-by-step explanation:

Given:

n = 35

P = 55% = 0.55

Q = 1 - p = 0.45

Computation:

Standard deviation σ = √npq

Standard deviation σ = √(35)(.55)(.45)

Standard deviation σ = 2.9432

Mean μ = np = 35 x 0.55 = 19.25

p[(x-np)/ σ ]

P[z<1.04204]

= 0.86 (Approx)

Answer:

The student is incorrect because I I or absolute value would make the -9 to positive 9.  

Step-by-step explanation:

-9<4

on a numberline

-9 -8 -7 -6 -5 -4 -3 -2 -1 0 1 2 3 4

but the absolute value of -9 (or) |–9|

is actually positive 9

Answer:

871

Step-by-step explanation:

737 divided by 11 is 67, so thats how many miles he drives per hour

67 times 13 is 871

Answer: 871 Miles

Work: So, I did 737 miles divided by 11 hours to find out how many miles he had driven in 1 hour, which is 67. I did 67 x 2 which is 134, and added it to 737, which will give us how much he will drive in 13 hours. And the answer is 871.

Merry Christmas! :)

Answer:

The equation of line is: [tex]\mathbf{4x-3y=-18}[/tex]

Step-by-step explanation:

We need to find an equation of the line that passes through the points (-6, -2) and  (-3, 2)?

The equation of line in slope-intercept form is: [tex]y=mx+b[/tex]

where m is slope and b is y-intercept.

We need to find slope and y-intercept.

Finding Slope

Slope can be found using formula: [tex]Slope=\frac{y_2-y_1}{x_2-x_1}[/tex]

We have [tex]x_1=-6,y_1=-2, x_2=-3, y_2=2[/tex]

Putting values and finding slope

[tex]Slope=\frac{2-(-2)}{-3-(-6)}\\Slope=\frac{2+2}{-3+6} \\Slope=\frac{4}{3}[/tex]

So, we get slope: [tex]m=\frac{4}{3}[/tex]

Finding y-intercept

Using point (-6,-2) and slope [tex]m=\frac{4}{3}[/tex] we can find y-intercept

[tex]y=mx+b\\-2=\frac{4}{3}(-6)+b\\-2=4(-2)+b\\-2=-8+b\\b=-2+8\\b=6[/tex]

So, we get y-intercept b= 6

Equation of required line

The equation of required line having slope [tex]m=\frac{4}{3}[/tex] and y-intercept b = 6 is

[tex]y=mx+b\\y=\frac{4}{3}x+6[/tex]

Now transforming in fully reduced form:

[tex]y=\frac{4x+6*3}{3} \\y=\frac{4x+18}{3} \\3y=4x+18\\4x-3y=-18[/tex]

So, the equation of line is: [tex]\mathbf{4x-3y=-18}[/tex]

Answer:

40

Step-by-step explanation:

162/4.1= 39.51 round to 40

The solution of the equation after dividing would be 40.

Used the concept of the divide that states,

The division method is used to distribute a group of things into equal parts. The division is just the opposite of multiplications.

Given that,

162 divided by 4.1

Now divide the numbers,

162 divided by 4.1

It can be written as,

162 ÷ 4.1

162 / 4.1

1620/41

This gives,

39.512

Rounded to whole numbers,

40

Therefore, the solution is 40.
