Answer 1

Answer:

17.5 ft

Step-by-step explanation:

Given

[tex]Ladder = 18ft[/tex]

[tex]\theta = 76[/tex]

Required

The height which the ladder reaches on the wall

The question is illustrated with the attached image (solve for x).

Using sine formula, we have:

[tex]\sin(76) = \frac{x}{18}[/tex] --- i.e. sin = opposite/hypotenuse

Make x the subject

[tex]x = 18 * \sin(76)[/tex]

[tex]x = 18 * 0.9703[/tex]

[tex]x = 17.4654[/tex]

Approximate

[tex]x = 17.5[/tex]

A manufacturer claims that a particular automobile model will get 50 miles per gallon on the highway. The researchers at a consumer-oriented magazine believe that this claim is high and plan a test with a simple random sample of 25 cars. What should the researchers conclude if the sample mean is 49 miles per gallon with standard deviation 2.3 miles per gallon

Answer:

Following are the responses to the given question:

Step-by-step explanation:

Therefore, the 0.02 p-value is sufficient proof to reject the claim form of the manufacturer.

How to solve (x+7)(x-9)>0

Answers

Answer:

x < -7, x > 9.

Step-by-step explanation:

Solve for x.

x = -7, 9

From the values of x above, we have these 3 intervals to test.

[tex]x < - 7[/tex]

[tex] - 7 <x < 9[/tex]

[tex]x > 9[/tex]

Pick a test point for each interval.

For the interval x < −7:

Let's pick x=−8. Then, (-8 + 7) (-8 - 9) > 0.

After simplifying, we get 17>0, which is true

Keep this interval.

Let's pick x=0. Then, (0+7)(0-9) > 0.

After simplifying, we get −63 > 0, which is false.

Drop this interval.

For the interval x > 9:

Let's pick x=10. Then, (10+7)(10-9)>0.

After simplifying, we get 17 > 0, which is true

Keep this interval.

Therefor, the answer is x < -7, x > 9.

An expression is shown below:

3x3y + 12xy − 9x2y − 36y
First Rewrite the expression so that the GCF is factored completely. Show the steps of your work.
Then Rewrite the expression completely factored. Show the steps of your work.

Answers

Answer:

Part A: so the GCF is 3y, 

We need to rewrite the equation such as: 

-36 as -12 · 3, -9 as -3 · 3, 12 as 4 · 3

It will look like this: 

3x^3 y +4 · 3xy + 3 · 3x^2 y + 4 · 3 · 3y

We then need to factor out 3y:

3y(x^3 + 4x - 3x^2 - 12)

Part b: factor out completely

3y(x^3 + 4x - 3x^2 - 12)

So, we need to do the following:

3y{x^2(x-3) + 4 (x-3)}

we then get the final factor: 3y(x - 3) (x^2 + 4)

Step-by-step explanation:

The factored expression is:

[tex]3y(x^3 + 4x - 3x^2 - 12)[/tex]

------------------------

To factor the expression:

First, we need to find the greatest common factor of the numeric and symbolic coefficients.Then, we divide each term of the expression by it's gcf.

------------------------

The expression is:

[tex]3x^3y + 12xy - 9x^2y - 36y[/tex]

------------------------

The numeric coefficients are: 3, 12, 9, 36

The gcf of the numeric coefficients is:

3 - 12 - 9 - 36|3

1 - 4 - 3 - 12

The gcf of the numeric coefficients is 3, as 3 is the only number by which 3, 12, 9 and 36 are all divisible.

------------------------

The symbolic coefficients are: [tex]x^3y, xy, x^2y, y[/tex]

The only common term is y, so y is the gcf of the symbolic coefficients.

------------------------

The gcf of the entire expression is the multiplication of the gcfs of the numeric and of the symbolic coefficients, so it is 3y.

Now, to factore the expression:

[tex]3x^3y + 12xy - 9x^2y - 36y = 3y(\frac{3x^3y}{3y} + \frac{12xy}{3y} - \frac{9x^2y}{3y} - \frac{36y}{3y}) = 3y(x^3 + 4x - 3x^2 - 12)[/tex]

The factored expression is:

[tex]3y(x^3 + 4x - 3x^2 - 12)[/tex]

What is the solution to the equation?

r/7.1 = 4.2

Answers

Answer:

r = 29.82

Step-by-step explanation:

We have the equation r/7.1 = 4.2 and are asked to solve for r.

To solve, we need to isolate r, do as followed and multiply 7.1 from both sides:

r/7.1 = 4.2

r = 29.82

Answer:

r = 29.82

Step-by-step explanation:

[tex]\frac{r}{7.1} = 4.2[/tex]

The opposite of division is multiplication, you will need to multiply 7.1 to both sides.

That would leave:

r = 4.2 (7.1)

r = 29.82

If there are further instructions for rounding, you can round.

Answers

The graph that represents a function is graph X

For a graph to represent a function, then the graph must pass the vertical line test.

This means that, no two output values of the graph must have the same input value.

The above statement can be interpreted as:

For every x value, there must be exactly one corresponding y value.

From the given graphs, only graph X passes the vertical line test, because every x value has exactly one corresponding y value.

Hence, the graph X represents a function

Answer:

  23) insufficient number of corresponding sides/angles

  24) insufficient number of corresponding sides/angles

Step-by-step explanation:

In general, you need at least 3 corresponding parts to show triangle congruence. At least one of those must be a side. The attachment shows the ways triangles can be declared congruent. (HL works for right triangles, because we know the right angles are congruent to each other.)

__

23) A side is shown congruent (KL ≅ GH), and we know the vertical angles at J are congruent. However, we need another angle before we can declare the ∆GHJ congruent to anything. (One more side doesn't do it, because the two sides would not be on either side of the angle at J.)

  Reason: insufficient data

__

24) A side is shown congruent (MP ≅ QS), and an angle is shown congruent (∠M ≅ ∠Q). As in the previous problem, we need at least one more angle, or we need to know that MN ≅ QR before we can declare the triangles congruent.

  Reason: insufficient data
