Step-by-step explanation:

Let Va = the velocity of the airplane

Let Vw = the velocity of the wind

When flying with the wind:

(Va+Vw)*(4 hours) = 4000

4Va + 4Vw = 4000

4Vw = 4000 - 4Va

Vw = 1000 - Va

When flying against the wind:

(Va-Vw)*(7 hours) = 4200 km

7Va - 7Vw = 4200

Substitute 1000-Va for Vw and solve for Va:

7Va - 7(1000-Va) = 4200

7Va -7000 + 7Va = 4200

14Va = 11200

Va = 800 km/hr

Rate of wind:

Vw = 1000 - Va = 1000 - 800 = 200 km/hour

Answer: h -18 =14

Step-by-step explanation:

You need to plug in -18 into the equation. So h(-18)=17+(-18)/6

h(-18)=17-3

h(-18)=14

Answer:

9.42

Step-by-step explanation:

Hey There!

The first step of this problem is to find the formula for arc length

[tex]arc-length=2\pi r(\frac{0}{360} )[/tex]

r=raduis

0 = angle

now we just plug in the values

[tex]arc-length=2\pi 10\frac{54}{360} \\2\pi =6.283185307\\6.283185307x10=62.83185307\\62.83185307\frac{54}{360}=9.424777961[/tex]

so the arc length equals 9.424777961

the last step is to round to the nearest hundreth

so your final answer is 9.42

Answer:

  7. D: (-∞, ∞); R: [3, ∞); see attached for a graph (red)

  8. a=0; see attached for a graph

Step-by-step explanation:

7. The function is a polynomial, so its domain is all real numbers.

The parabola opens upward. It has a minimum value of 3. The range is y ≥ 3.

__

8. Putting the given point coordinates in the equation, we can solve for a.

  f(7) = 6

  6 = a(7 -5)² +6

  0 = a(2²)

  0 = a

The value of a is zero.

(The given point has the same y-value as the vertex, but is not the vertex. The function can only go through that point if it is a horizontal line (not a parabola).) The attachment shows a graph.

Answer:

a. The population

b. The accessible population

c. The sample

d. The statistic

Step-by-step explanation:

a. All the homeowners in the researchers state = The target population

b. The 879 homeowners whose name were obtained = The sample frame (accessible population)

c. The 64 homeowners who returned the questionnaire = Research participants (the sample), the subjects

d. The 80% who stated that the current home warranty coverage needs to be completely overhauled = The statistic (subset or part of the sample)

Answer:

4x19+4x2  or  4x21

Step-by-step explanation:

If you multiply 4x19, you get  76. And if you multiply 4x2 you get 8. 76+8= 84

If you multiply 4x21 you get 84 also.  Both of these answers are distributive property. (all it is, is different ways of solving the problem.)

Answer:

The easiest way to figure this is to find P(no girls in 5 births) = (1/2)^5 = 1/32 -------------- The P(at least one girl in 5 births) = 1 - 1/32 = 31/32

The probability that when they have five children, at least one of them is a boy is 31/32

Probability is the likelihood or chance that an event will occur.

Probability = Expected outcome/Total outcome:

The probability that a couple will have a boy or girl among the five children = 1/2

If they gave birth to 5 children:

The probability that when they have five children, at least one of them is a boy = 1 - (1/2)^n where:

n is the total number of children

The probability that when they have five children, at least one of them is a boy = 1 - (1/2)ⁿ

The probability that when they have five children, at least one of them is a boy = 1 - (1/2)⁵

The probability that when they have five children, at least one of them is a boy = 1- 1/32 = 31/32

Hence the probability that when they have five children, at least one of them is a boy is 31/32

(2x-5)(x-2)

Answer:

y = -3x + 5

Step-by-step explanation:

Since the y-intercept occurs at the point (0,5), you can use that and the point slope equation to find the equation.

This looks like y - 5 = -3 (x - 0);

Solving for y, you get y = -3x + 5;

To graph this equation you would put one point at (0,5), then use the slope to count down three and to the left one to find other points, or you could just plug in numbers for x to find their corresponding y values and plot it like that.

Hopefully this helps- let me know if you have any questions!

Answer:

x = 9

Step-by-step explanation:

If g(x) = 3, that means that the output is three.

Outputs are y values.

Look at the graph. When y=3, the x  = 9.

So the input value for which g(x) = 3 (aka that gives the output y = 3) is x = 9

Answer:

1. -25

2. 2.1

Step-by-step explanation:

-1/2(x + 5) = 10

divide both sides by 2.

-1(x + 5) = 20

-(x + 5) = 20

-x = 20 + 5

x = -25

k/3.5 + 7.4 = 8

2k/7 +37/5 = 8

10k = 280 - 259

10k = 21

k = 21/10 (2.1)

Answer:

1.x=15

2.k=2.1

Step-by-step explanation:

1.-1/2(x+5)=-10

 -x+5/2=-10 multiply both sides by 2

  -x-5=-10

  -x=-20+5

 -x=-15 multiply both sides by -1

  x=15

2.k/3.5+7.4=8

 k/3.5=8-7.4

  k/3.5=0.6

 multiply both sides by 3.5

  k=2.1

Answer:

90+42+x = 180

132+x=180

x=180-132

x=48

Answer:

48 DEGREES

Step-by-step explanation:

First you need to find the other two angles : 42 + 90 = 132 ( the 90 comes from the little square like shape on the other angle).

So x = 180 - 132 = 48 ( we use 180 because it is the sum of interior angles of a triangle.
