Bashir works in a weather station and has launched a weather balloon. The height of the balloon is 4 kilometers and it is 1 kilometer from the station. In kilometers, what is the approximate distance between the station and the balloon?

Answers

Answer 1

Consider triangle WBG, where points W, B and G represent Weather Station, Balloon and Ground, respectively. This triangle is right with right angle at vertex G. The legs of this triangle are GB and GW, the hypotenuse is BW.

From the question you know that GB=4 km and GW=1 km. By the Pythagorean theorem,

[tex]BW^2=GB^2+GW^2,\\ \\BW^2=4^2+1^2,\\ \\BW^2=17,\\ \\BW=\sqrt{17}\approx 4.123\text{ km.}[/tex]

There are 144 people in line. There are twice as many adults as children in line .How many children in line and how many adults are in line?

Answers

48 children and 96 adults

let x be the number of children then number of adults = 2x and

x + 2x = 144

3x = 144 ( divide both sides by 3 )

x = [tex]\frac{144}{3}[/tex] = 48

There are 48 children and ( 2 × 48 ) = 96 adults


Final answer:

There are 48 children and 96 adults in line.

Explanation:

To find how many children and adults are in line, we can use algebraic equations and solve for each variable. Let's assume the number of children in line is x. Since there are twice as many adults as children, the number of adults in line would be 2x. According to the given information, the total number of people in line is 144. Therefore, we can set up the equation x + 2x = 144. Simplifying the equation, we get 3x = 144. Dividing both sides by 3, we find x = 48. So, there are 48 children and 2 * 48 = 96 adults in line.

The height of a football during a punt is modeled by h=-16t^2+60t+3. If the football hits the ground, how long did it stay in the air?

Answers

"how long..." is asking for time (t).  "The amount of time spent in the air" is the time from when the ball was kicked (0 seconds) to the time it landed on the ground.  Need to find the x-intercepts (one will be negative which will be invalid). You can do this by factoring ... or by using the quadratic formula. With the equation you provided, it is not factorable, so you must use the quadratic formula.

h = -16t² + 60t + 3

   a=-16   b=60  c=3

[tex]t = \frac{-b +/- \sqrt{b^{2}-4ac } }{2a}[/tex]

[tex]t = \frac{-60 +/- \sqrt{60^{2}-4(-16)(3) } }{2(-16)}[/tex]

[tex]t = \frac{-60 +/- \sqrt{3600 + 192} }{-32}[/tex]

[tex]t = \frac{-60 +/- \sqrt{3792} }{-32}[/tex]

[tex]t = \frac{-60 +/- 61.6}{-32}[/tex]

[tex]t = \frac{-60 + 61.6}{-32}[/tex]   or   [tex]t = \frac{-60 - 61.6}{-32}[/tex]

[tex]t = \frac{1.6}{-32}[/tex]        or     [tex]t = \frac{-121.6}{-32}[/tex]

Which function passes through the points (2, 15) and (3, 26)? A. y = 11x + 7 B. y = 11x − 7 C. y = 7x + 11 D. y = -11x − 7 E. y = 7x − 11

Answers

Answer:

B is the correct answer.

Final answer:

The function that passes through the points (2, 15) and (3, 26) is B) y = 11x - 7.

Explanation:To find the function that passes through the points (2, 15) and (3, 26), we can use the point-slope form of a linear equation, y - y1 = m(x - x1). Using the first point (2, 15), we can substitute the values into the equation and solve for the slope, m. Then, we can use the slope to find the y-intercept, b, by substituting the values of a point into the slope-intercept form of a linear equation, y = mx + b.

The function that passes through the given points is B) y = 11x - 7.

Each x value has one and only one y value.

Answers

D, Each x value has one and only one y value.; This is because if an x-value repeats itself then it is not a function. You can test this on a graph by drawing a vertical line on it. If the vertical line intercepts the line more than once anywhere on the graph, then it is not a function.

Answer:

Each x value has one and only one y value.

Step-by-step explanation:

y = f(x) can be called a function if, and only if

f(a) = f(b) means that a = b.

That is, each x value has one and only one y value.

y = 4 - 6x

f(a) = f(b)

4 - 6a = 4 - 6b

6b = 6a

b = a

So the correct answer is:

Each x value has one and only one y value.

Writing a Polynomial Function Given a y-Intercept:

Suppose the graph of a cubic polynomial function has the same zeroes and passes through the coordinate (0, –5).
Describe the steps for writing the equation of this cubic polynomial function.

Answers

We are given

a cubic polynomial function has the same zeroes

Let's assume that zeros as 'a'

so, we can write it as

[tex]f(x)=(x-a)^3[/tex]

now, we are given y-intercept

(0,-5)

at x=0 , y=-5

we can use it and then find 'a'

[tex]-5=(0-a)^3[/tex]

[tex]a=\sqrt[3]{5}[/tex]

now, we can plug it

and we get

[tex]f(x)=(x-\sqrt[3]{5})^3[/tex]..................Answer

Answer:

Use the zeroes to determine the roots.

Write the polynomial as a product of the leading coefficient, a, and the factors, where each factor is x minus a root.

Use the y-intercept (0, –5) to solve for the leading coefficient.

Substitute the leading coefficient into the polynomial function for a and simplify.

Perform the indicated operation and then simplify 4m-3-9m+8

Answers

Final answer:

To simplify 4m - 3 - 9m + 8, combine like terms to get -5m + 5, which is the simplified expression.

Explanation:

To perform the indicated operation and simplify 4m - 3 - 9m + 8, we need to combine like terms. The terms 4m and -9m are like terms, as are the constants -3 and +8. So, let's combine them.

First, combine the m terms:

4m - 9m = -5m

Next, combine the constant terms:

-3 + 8 = 5

Putting it all together, we have:

-5m + 5

This is the simplified form of the original expression.

What is the slope of the line shown below?

Answers

answer B or 1/6  should be right.

Answer:  The correct option is

(B) [tex]\dfrac{1}{6}.[/tex]

Step-by-step explanation:  We are given to find the slope of the straight line shown in the graph.

From the graph, we see that the line passes through the points (-6, 3) and (12, 6).

The SLOPE of a line passing through the points (a, b) and (c, d) is given by

[tex]m=\dfrac{d-b}{c-a}.[/tex]

Therefore, the slope of the given line is

[tex]m=\dfrac{6-3}{12-(-6)}=\dfrac{3}{12+6}=\dfrac{3}{18}=\dfrac{1}{6}.[/tex]

Thus, the slope of the given line is [tex]\dfrac{1}{6}.[/tex]

Is y=3x+4; y2=6x+8 a one solution, infinitely many solution, or no solution problem

Answers

Answer:

Infinitely many.

Step-by-step explanation:

y = 3x + 4

2y = 6x + 8

Basically you would fill in the variable for y into the second equation.

2 (3x + 4) = 6x + 8

Multiply 2 by the part in the parenthesis.

2 * 3x = 6x

2 * 4 = 8

Set up the equation and solve

6x + 8 = 6x + 8

Because the sides are the same, they cancel each other out. When two sides equal the same variable they have infinitely many solutions.

The vertex of this parabola is at (3,-2). when the x-value is 4, the y-value is 3. whatis the coefficient of the squared expression in the parabolas equation

Answers

Answer:

The coefficient of the squared expression in the parabolas equation will be 5.

Step-by-step explanation:

The vertex form of parabola is:  [tex]y=a(x-h)^2 +k[/tex] , where [tex](h,k)[/tex] is the vertex point and [tex]a[/tex] is the coefficient of [tex]x^2[/tex] term.

The vertex is given as [tex](3,-2)[/tex]. That means, [tex]h=3[/tex] and [tex]k=-2[/tex]

So, the vertex form will be:  [tex]y=a(x-3)^2-2[/tex]

Given that, when the x-value is 4, the y-value is 3. So, plugging these values into the above equation, we will get.....

[tex]3=a(4-3)^2-2\\ \\ 3=a(1)^2-2\\ \\ a=3+2=5[/tex]

Thus, the coefficient of the squared expression in the parabolas equation will be 5.
