The length of the missing side (the hypotenuse) is 10 ft.

We have,

We can use the Pythagorean theorem to find the length of the missing side of the right triangle.

So,

a² + b² = c²

where a and b are the lengths of the legs, and c is the length of the hypotenuse.

In this case,

The opposite side (which is the leg) has a length of 8 ft, and the adjacent side (which is the other leg) has a length of 6 ft.

Let x be the length of the missing side. Then we have:

a = 8 ft

b = 6 ft

c = x

Plugging these values into the Pythagorean theorem, we get:

8² + 6² = x²

64 + 36 = x²

100 = x²

Taking the square root of both sides, we get:

x = √100 = 10 ft

Therefore,

The length of the missing side (the hypotenuse) is 10 ft.

Let's say the total work to be done is represented by 1.

On the first day, three-fifths of the work is completed. Therefore, the remaining work to be done is 1 - 3/5 = 2/5.

On the second day, three-quarters of the remainder is completed. The remainder after the first day's work is 2/5. So, the work completed on the second day is 3/4 x 2/5 = 3/10. The remaining work to be done is 2/5 - 3/10 = 1/5.

On the third day, seven-eighths of what remained is done. The remaining work to be done after the second day's work is 1/5. So, the work completed on the third day is 7/8 x 1/5 = 7/40.

Therefore, the fraction of work still remaining to be done is 1/5 - 7/40 = 8/40 - 7/40 = 1/40.

The seismograph reading of the earthquake is approximately 1.99526.To determine the seismograph reading of the earthquake with a magnitude of 3.3 on the Richter scale, we can use the formula M(I) = log(I/0.001), where M(I) represents the magnitude and I represents the intensity of the earthquake.

In this case, we are given the magnitude of 3.3. Let's substitute this value into the formula and solve for I:

3.3 = log(I/0.001)

To isolate I, we need to convert the equation into exponential form:

10^(3.3) = I/0.001

Simplifying the equation, we have:

I = 10^(3.3) * 0.001

Using a calculator, we find that 10^(3.3) is approximately 1995.26.

So, the seismograph reading of the earthquake is:

I = 1995.26 * 0.001

The greatest number of 4 cm cubes that Haley can fit in the box and still be able to close the lid is 6.

First, we need to determine the dimensions of the box in terms of the length of a side of a cube. We can do this by finding the smallest dimension of the box and dividing it by the length of the side of a cube.

The smallest dimension of the box is the height, which is 6 cm. Therefore, the length of the side of a cube must be a factor of 6.

The length and width of the box are both 8 cm, so the length of the side of a cube must be less than or equal to 8 cm.

We can check the factors of 6 to find the largest possible size of the cube that can fit in the box:

A cube with side length 6 cm would fit in the box, but the lid would not be able to close.

A cube with side length 4 cm would fit in the box, and the lid would be able to close, so this is the largest size cube that can fit in the box.

To determine how many 4 cm cubes can fit in the box, we need to find the volume of the box and divide by the volume of a single cube. The volume of the box is:

V_box = length x width x height

V_box = 8 cm x 8 cm x 6 cm

V_box = 384 cm³

The volume of a single 4 cm cube is:

V_cube = side length³

V_cube = 4 cm x 4 cm x 4 cm

V_cube = 64 cm³

Dividing the volume of the box by the volume of a single cube gives us the maximum number of cubes that can fit in the box:

384  / 64  = 6

Therefore, the greatest number of 4 cm cubes that Haley can fit in the box and still be able to close the lid is 6.

11.7b

Step-by-step explanation:

If you do 339.30 divided by 29 it equals 11.7 but the full equation would be c=11.7b

The proportional equation for the total cost 'c' in terms of the number of boxed lunches 'b' is:

c = (339.30 / 29) * b

What is proportion?

The size, number, or amount of one thing or group as compared to the size, number, or amount of another. The proportion of boys to girls in our class is three to one.

Let's assume that each boxed lunch costs the same amount, denoted by the variable 'x'.

We are given that the company ordered 29 boxed lunches for a total cost of $339.30. Therefore, we can write the equation:

29x = 339.30

To find the cost 'c' for any number 'b' of boxed lunches, we can set up a proportion:

29x / 29 = 339.30 / b

Simplifying this equation, we get:

x = 339.30 / 29

Now, we can substitute this value of 'x' back into the equation:

c = bx = b * (339.30 / 29)

Therefore, the proportional equation for the total cost 'c' in terms of the number of boxed lunches 'b' is:

c = (339.30 / 29) * b

Answer:

y - 4 = 1/3(x + 5)

Step-by-step explanation:

The general equation for the point-slope form of a line is given by:

y - y1 = m(x - x1), where

Step 1:  To find the equation of the line through (-5, 4) and (1, 6), we first need to find the slope of the line using the slope formula, which is:

m = (y2 - y1) / (x2 - x1), where

We can allow (-5, 4) to be our (x1, y1) point and (1, 6) to be our (x2, y2) point:

m = (6 - 4) / (1 - (-5))

m = 2 / (1 + 5)

m = 2/6

m = 1/3

Now we can use the point-slope form of the equation with either of the two points.  

y - 4 = 1/3(x - (-5))

y - 4 = 1/3(x + 5)

Thus, the point-slope equation of the line through (-5, 4) and (1, 6) is:

y - 4 = 1/3(x + 5)

We cannot find the value of y'' at the point where x = 0 using this method.

To find y'' at the point where x = 0, we need to differentiate the given equation twice with respect to x.

First, we take the derivative of both sides with respect to x:

y + xy' + 4ey' = 0

Next, we take the derivative of this equation with respect to x:

y' + xy'' + y' + 4ey'' = 0

Simplifying this expression, we get:

2y' + xy'' + 4ey'' = 0

We are given that xy + 4ey = 4e. Differentiating this equation with respect to x, we get:

y + xy' + 4ey' = 0

Substituting y' = -(y + 4ey')/x from this equation into the previous equation, we get:

2y' - (y + 4ey') + 4ey'' = 0

Simplifying this expression, we get:

y'' = (y + 4ey' - 2y')/(4e)

When x = 0, we have y = 4e/4e = 1 and y' = -(1 + 4e*y')/0, which is undefined.

The quantity 1.0 mg/cm2 is the same as 1.0 x 10-4 kg/m2.

To convert from milligrams per square centimeter (mg/cm2) to kilograms per square meter (kg/m2), we need to use conversion factors to adjust the units. The given options represent different powers of 10 that can be used as conversion factors.

We know that 1 kilogram (kg) is equal to 1,000,000 milligrams (mg), and 1 meter (m) is equal to 100 centimeters (cm). Therefore, we can express the conversion factors as follows:

1 kg = 1,000,000 mg (1)

1 m2 = 10,000 cm2 (2)

To convert from mg/cm2 to kg/m2, we can combine these conversion factors:

1 mg/cm2 = (1 mg / 1 cm2) x (1 kg / 1,000,000 mg) x (10,000 cm2 / 1 m2)

Simplifying the expression, we have:

1 mg/cm2 = (1 / 1,000,000) kg/m2 = 1 x 10-6 kg/m2

Therefore, the quantity 1.0 mg/cm2 is the same as 1.0 x 10-6 kg/m2.

Answer:

y = 4x^2 + 32x + 28

Step-by-step explanation:

Before we can find the standard form of the quadratic function with the given coordinates, we must first start with the intercept form, whose general equation is

y = a(x - p)(x - q), where

Step 1:  We can plug in (-6, -20) for x and y, -7 for p and -1 for q into the intercept form.  This will allows us to solve for a:

-20 = a(-6 - (-7))(-6 - (-1))

-20 = a(-6 + 7)(-6 + 1)

-20 = a(1)(-5)

-20 = -5a

4 = a

Thus, the full equation in vertex form is

y = 4(x + 7)(x + 1).

Step 1:  The general equation for standard form is

y = ax^2 + bx + c.

We can convert from vertex to standard form by simply expanding the expression.  Let's ignore the 4 for a moment simply focus on (x + 7)(x + 1).

We can expand using the FOIL method, where you multiply

We see that the first terms are x and x, the outer terms are x and 1, the inner terms are 7 and x and the last terms are 7 * 1.  Now, we multiply and simplify:

(x * x) + (x * 1) + (7 * x) + (7 * 1)

x^2 + x + 7x + 7

x^2 + 8x + 7

Step 3:  Now, we can distribute the four to each term with multiplication:

4(x^2 + 8x + 7)

4x^2 + 32x + 28

Optional Step 4:  We can check that our quadratic function in standard form, by plugging in -7, -1, and -6 for x and seeing that we get 0 as the y value for both x = -7 and x = -1 and -20 as the y value for x = -6:

Checking that (-7, 0) lies on the parabola of 4x^2 + 32x + 28:

0 = 4(-7)^2 + 32(-7) + 28

0 = 4(49) - 224 + 28

0 = 196 - 196

0 = 0

Checking that (-1, 0) lies on the parabola of 4x^2 + 32x + 28:

0 = 4(-1)^2 + 32(-1) + 28

0 = 4(1) - 32 + 28

0 = 4 - 4

0 = 0

Checking that (-6, -20) lies on the parabola of 4x^2 + 32x + 28:

-20 = 4(-6)^2 + 32(-6) + 28

-20 = 4(36) -192 + 28

-20 = 144 -164

-20 = -20

I attached a graph from Desmos to show how the function y = 4x^2 + 32x + 28 contains the points (-7, 0), (-1, 0), (-6, 20), further proving that we've correctly found the quadratic function in standard form passing through these three points

The correct sequence of transformations that could have been used to transform Trapezoid ABCD to produce trapezoid A''B''C''D'' is that trapezoid ABCD was reflected across the y-axis and then across the x-axis.

To transform trapezoid ABCD into trapezoid A''B''C''D'', we need to apply a sequence of transformations that will result in the same size and shape of the two trapezoids, which means that they are congruent.

One possible sequence of transformations that could have been used to transform trapezoid ABCD to produce trapezoid A''B''C''D'' is:

Trapezoid ABCD was reflected across the y-axis and then across the x-axis.

This sequence of transformations would result in the same size and shape of the two trapezoids, which means that they are congruent. Let's see why this is true.

When we reflect trapezoid ABCD across the y-axis, each point on the trapezoid is reflected across the y-axis, which means that its x-coordinate is multiplied by -1 while its y-coordinate remains the same. This results in a mirror image of the trapezoid on the opposite side of the y-axis.

Next, when we reflect the trapezoid across the x-axis, each point is reflected across the x-axis, which means that its y-coordinate is multiplied by -1 while its x-coordinate remains the same. This results in a mirror image of the trapezoid on the opposite side of the x-axis.

The resulting trapezoid is now in the same position and orientation as trapezoid A''B''C''D'', but it may not be in the same location. However, since the trapezoid is congruent, we can translate it to match the position of trapezoid A''B''C''D''.

The rate of change of a periodic function is itself a periodic function. In the case of a sinusoidal wave, the derivative is also a sinusoidal wave with the same period, but shifted by a phase angle of [tex]π/2.[/tex]

The rate of change of a periodic function at a specific point is equal to the instantaneous slope of the tangent line to the graph of the function at that point.

To calculate the rate of change of a periodic function, you need to take the derivative of the function with respect to the independent variable (usually time). If the function is a sinusoidal wave, you can use trigonometric identities to find the derivative.

For example, let's say we have a function f(t) = sin(t), which represents a sinusoidal wave. To find the rate of change of the function at a particular point t = a, we need to take the derivative of the function with respect to t:

f'(t) = cos(t)

Then we can evaluate this derivative at t = a to find the rate of change at that point:

f'(a) = cos(a)

This tells us the instantaneous rate of change of the function at the point t = a.

The probability that the kicker makes his first two kicks is 63.21%. This means that out of 100 attempts, the kicker is likely to make both kicks 63 times.

To solve this problem, we need to use conditional probability. We know that the kicker usually makes 71% of his first field goal attempts. So, the probability that he makes his first kick is 0.71. If he makes his first attempt, his success rate rises to 89%. So, the probability that he makes his second kick given that he made his first kick is 0.89.
Now, to find the probability that he makes his first two kicks, we need to multiply the probability of him making his first kick by the probability of him making his second kick given that he made his first kick. This can be represented as:
P(2 successful kicks) = P(1st kick is successful) x P(2nd kick is successful | 1st kick is successful)
P(2 successful kicks) = 0.71 x 0.89
P(2 successful kicks) = 0.6321 or 63.21%
