The cat will be waiting and meowing at his bowl for 18.3 seconds.

The time it takes the cat to reach the bowl = 3.7 seconds (17/10 + 2)

The time it takes the woman to reach the bowl = 17 seconds (17/1)

The total time it takes the woman to put the food = 22 seconds (17 + 3 + 2)

Waiting time = 18.3 seconds (22 - 3.7)

Distance to the cabinet = 12 meters

Distance to the bowl = 5 meters

Total distance to be covered = 17 meters

Speed of the cat = 10 meters/s

Speed of the woman = 1 meter/s

Thus, since the time it takes is dependent on the speed of both, the cat will be waiting and meowing at his bowl for 18.3 seconds.

The equation 3x² - 48x + 6856 represents the area of the gym and track together in terms of width.

It is defined as the area occupied by the rectangle in two-dimensional planner geometry.

The area of a rectangle can be calculated using the following formula:

Rectangle area = length x width

We have:

A rectangular building for a gym is three times as long as it is wide. Just inside the walls of the building, there is a 6ft rectangular track along the walls of the gym and has an area of 7000ft²

Let x be the width of the rectangle.

As the area of track along the walls of the gym is 7000ft²

(x - 12)(3x - 12) = 7000

After simplifying:

3x² - 48x + 6856 = 0

Thus, the equation 3x² - 48x + 6856 represents the area of the gym and track together in terms of width.

The first angle is 33.8° and second angle is 56.2°.

If the sum of the two angles is equal to the measurement of a right angle then the pair of angles is said to be complementary angles.

Complementary angles are the angles whose sum makes 90⁰.

Let's say our first angle is x:

x = first angle

According to the question,

The other angle is 22.4° more than the complementary angle.

Therefore, 22.4° will be added to the other angle.

first angle  = x

second angle = x + 22.4°

Since, complementary angle is equal to the sum of the two angles to be 90°.

∴ x + x + 22.4°  = 90°

    2x = 90 ° - 22.4°

    2x = 67.6°

     x = 67.6° / 2

     x = 33.8°

Thus, the first angle is 33.8° and second angle is 56.2°.

Answer:

Step-by-step explanation:

2. Given a point with integral coordinates (a, b):

   Vertical line that contains (a, b):

       So here it's not to hard, all you have to understand, is what a vertical line is. If you were to draw a vertical line, you would notice that the x-values remain constant, and the only thing that changes is the y-value. So you're going to have an equation as such: x=a, where a is some constant value, and y is literally anything. So in this case b doesn't matter. The only thing that matters is that x=a. Which is the equation. As long as x is equal to a, it should pass through (a, b)

   Horizontal line that contains (a, b):

       So this is very similar to the vertical line, as one of the values is constant, although the variable that's constant is different. If you were to draw a horizontal line, you would notice the x is changing, but the y-value isn't. This means the y is going to equal to constant value, which may look something like: y=b, which is the equation in this case, since as long as y=b, then the x should at some point equal a on the horizontal line

Why is it impossible to write the equation of a vertical line in slope-intercept form:

   As mentioned before, in a vertical line, the only thing that varies is the y-value, so if you wrote a vertical line as such: y=mx+b, then the x-value would have to vary. But if we were to put restrictions on the equation so that x can only equal some constant value, that means y would only be one point, but if you draw a vertical line, you would know that the y-value is all real numbers (unless of course you put some range restriction), but even then it's going to be more than one number. The other thing is to write an equation in slope-intercept form, you need to know the slope. which is defined as [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]. and by definition a vertical line only varies in y-values and not x. The value of x is defined in the constant equation: x=a. So the slope would be defined as: [tex]\frac{y_2-y_1}{a-a} = \frac{y_2-y_1}{0} = \text{undeefined}[/tex] ("I typed undefined wrong intentionally since it won't let me type it for some reason"). anyways the point is you can divide by 0. So main takeaways: the x-value can't vary, the formula has to output all real numbers for the y-value (unless some range restriction), the slope will have 0 as the denominator since x doesn't vary meaning x_2 - x_1 will = 0, because x_2 = x_1 (because x doesn't vary)

Given an equation in point slope form, explain how to determine the coordinate of the y-intercept:

   There are two ways to do this. The point slope form is expressed as such: y-a = m(x-b). But the m can be distributed so the equation becomes y-a = mx-mb and then add "a" to both equations to get y=mx -mb+a, in this case (0, -mb+a) will be the y-intercept, because if you plug in x as 0, mx will become 0 and it will leave these two values. You could also just of course plug in 0 as x in the point slope intercept form: y-a = m(x-b) and then solve for y. This gives the same result as it simplified to y-a = m(-b) which becomes y-a=-mb which then becomes y=-mb+a.

The two general approaches are qualitative and quantitative.

1. There's so much wrong with the suggested solution that it's hard to pinpoint the exact error. The "logic" is inconsistent - why do the [tex]x[/tex] and constant term stay in the denominator but the [tex]x^2[/tex] term does not?

What should be done is factorization in the numerator and denominator:

[tex]x^2 + 2x - 8 = (x + 4) (x - 2)[/tex]

[tex]x^2 + 6x - 16 = (x + 8) (x - 2)[/tex]

Then in the quotient, the factors of [tex]x-2[/tex] cancel so that

[tex]\dfrac{x^2+2x-8}{x^2+6x-16} = \dfrac{(x+4)(x-2)}{(x+8)(x-2)} = \boxed{\dfrac{x+4}{x+8}}[/tex]

2. Use the same strategy: factorize everything everything you can, then cancel anything you can.

[tex]x^2 - 9 = (x-3) (x+3)[/tex]

[tex]x^2+x-2 = (x+2)(x-1)[/tex]

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

y = -x - 12 + 10

Evaluate

y = -x - 2

9. y = -1/6x + 1; (-2, -9)

This gives

y = 6(x + 2) - 9

Evaluate

y = 6x + 12 - 9

This gives
