Answer:y = -2/3x + 490

Step-by-step explanation:

2x +3y = 1470  

Slope intercept form definition: y = mx + b is the slope-intercept form of a line where m is the slope and b is the y-intercept.  

2x + 3y = 1470  

2x + 3y -2x = 1470 - 2x - Subtract 2x from both sides  

3y = 1470 - 2x - Simplify  

3y/3 = 1470/3 - 2x/3 - Divide both sides by 3  

y = -2/3x + 490 - Simplify  

-⅔ is the slope and 490 is the y-intercept

Answer:

y= Ix-3I    (that says absolute value btw)

Step-by-step explanation:

This is the result of starting with y = |x|, then shifting it three units to the right. Replacing x with x-3 moves the xy axis three units to the left, giving the illusion the V shaped curve moved 3 spots to the right.

We don't shift up or down since the vertex is on the x axis.

We also don't vertically compress or stretch the graph either.

Side note: the vertex for this graph is (3,0) which is the lowest point of the curve.

After 3.5 days, the height of the plant is 5.75 centimeters.

h = 0.5(3.5) + 4

h = 1.75 + 4

height = 5.75 cm after 3.5 days.

The height of the plant is 6.25 centimeters after 4.5 days.

6.25 = 0.5d + 4

6.25 - 4 = 0.5d - 4

2.25 = 0.5d

2.25/0.5 = 0.5d/0.5

4.5 = d

days = 4.5

Thus, the height of the plant is 6.25 centimeters after 4.5 days.

After 3.5 days, the height of the plant is 5.75 centimeters and the height of the plant is 6.25 centimeters after 4.5 days.

A straight line is a combination of endless points joined on both sides of the point.

The slope 'm' of any straight line is given by:

\(\rm m =\dfrac{y_2-y_1}{x_2-x_1}\)

The equation of the line is:

h = 0.5d + 4

After rewriting the function:

f(x) = 0.5x + 4

Plug x = 0

f(0) = 4 cm

f(1) = 4.5 cm

f(2) = 5 cm

f(3) = 5.5 cm

f(4) = 6 cm

f(5) = 6.5 cm

Plug x = 3.5 days

f(3.5) = 5.75 cm

Plug f(x) = 6.25

6.25 = 0.5x + 4

2.25 = 0.5x

x = 4.5 days

Thus, after 3.5 days, the height of the plant is 5.75 centimeters and the height of the plant is 6.25 centimeters after 4.5 days.

To determine the angle of the first-order maximum for light with a wavelength of 652 nm passing through a bird feather acting as a diffraction grating, we need to apply the principles of diffraction and use the formula for calculating the angular position of diffraction maxima.

When light passes through a diffraction grating, such as the structures on a bird feather, it undergoes diffraction, resulting in the formation of interference patterns. The angle at which the maxima occur depends on the wavelength of light and the spacing between the diffracting elements.

Given that the bird feather acts as a diffraction grating with 7000 lines per centimeter, we can calculate the grating spacing (d) using the formula:

d = 1 / (number of lines per unit length),

d = 1 / (7000 lines/cm).

Next, we can calculate the angle of the first-order maximum using the formula for diffraction:

sinθ = mλ / d,

where θ is the angle, m is the order of the maximum (in this case, m = 1), λ is the wavelength of light, and d is the grating spacing.

In this case, we have the wavelength λ = 652 nm (or 6.52 x 10^-5 cm) and the grating spacing d calculated in the previous step.

Plugging in the values, we can solve for the angle θ using the equation:

sinθ = (1)(6.52 x 10^-5) / d.

By solving this equation, we can determine the angle of the first-order maximum for light with a wavelength of 652 nm passing through the bird feather acting as a diffraction grating.

The quadratic equation that represents the solution is F: p(x) = x² - 49.

The term "quadratic" refers to functions where the highest degree of the variable (in this example, x) is 2. A quadratic function's graph is a parabola, which, depending on the sign of the leading coefficient a, can either have a "U" shape or an inverted "U" shape.

Algebra, geometry, physics, engineering, and many other branches of mathematics and science all depend on quadratic functions. They are used to simulate a wide range of phenomena, including population dynamics, projectile motion, and optimisation issues.

Given that the solution of the quadratic function are x = -7 and x = 7 thus we have:

p(x) = (x + 7)(x - 7)

Solving the parentheses we have:

p(x) = x² - 7x + 7x - 49

Cancelling the same terms with opposite sign we have:

p(x) = x² - 49

Hence, the quadratic equation that represents the solution is F: p(x) = x² - 49.

To find out how many adult and children's tickets were sold at the Community Theater production of A Comedy of Errors, we can use the following system of equations:

Let x represent the number of adult tickets, and y represent the number of children's tickets.

1) x + y = 3800 (total tickets sold)
2) 9x + 6.5y = 30,495 (total revenue)

Step 1: Solve equation 1 for x or y. We can solve for x:

x = 3800 - y

Step 2: Substitute the expression for x from step 1 into equation 2:

9(3800 - y) + 6.5y = 30,495

Step 3: Simplify the equation and solve for y:

34,200 - 9y + 6.5y = 30,495

-2.5y = -3,705

y = 1,482

Step 4: Substitute the value of y back into the expression for x:

x = 3800 - 1,482

x = 2,318

So, 2,318 adult tickets and 1,482 children's tickets were sold at the Community Theater production of A Comedy of Errors.

There would be 2314 adult tickets and 1486 children's tickets were sold.

Let X be the number of adult tickets sold, and Y be the number of children's tickets sold. We can write two equations based on the given information:

X + Y = 3800 (equation 1)

9X + 6.5Y = 30495 (equation 2)

Equation 1 represents the total number of tickets sold, and equation 2 represents the total revenue earned from the ticket sales.

To solve for X and Y, we can use the method of substitution. Rearranging equation 1, we get:

X = 3800 - Y

Substituting this expression for X into equation 2, we get:

9(3800 - Y) + 6.5Y = 30495

Expanding and simplifying, we get:

34200 - 9Y + 6.5Y = 30495

-2.5Y = -3715

Y = 1486

Substituting this value for Y into equation 1, we get:

X + 1486 = 3800

X = 2314

Therefore, 2314 adult tickets and 1486 children's tickets were sold.

To solve the triangle with side lengths a = 4.31 m, c = 5.77 m, and angle B = 26.8°, we can use the Law of Sines.

The Law of Sines states that for any triangle, the ratio of the length of a side to the sine of the angle opposite that side is constant.

We can use the Law of Sines to find the length of side b:

sin(B) / b = sin(A) / a

sin(26.8°) / b = sin(A) / 4.31

To find the length of side b, we rearrange the equation:

b = (sin(26.8°) * 4.31) / sin(A)

Now, we need to find angle A. Since the sum of angles in a triangle is 180°, we can find angle A using:

A = 180° - B - C

A = 180° - 26.8° - C

Now, we can substitute the given values into the equations:

A = 180° - 26.8° - 90°

A = 63.2°

Finally, we can substitute the values of angle A and side a into the equation to find the length of side b:

b = (sin(26.8°) * 4.31) / sin(63.2°)

b ≈ 2.78 m

Therefore, the length of side b is approximately 2.78 m and the measure of angle A is approximately 63.2°.

Stephen makes the mistake in the expression as he uses the 4 in the root and the 3 in the power and the expression actually is: ∛(16)/e

We start with the expression:

exp( (4/3)*ln(2) - 1)

Here we can use that:

exp(ln(x)) = x.

and e^(a + b) = e^a*e^b.

the first step here is:

e^((4/3)*ln(2) - 1) = e^((4/3)*ln(2)*e^(-1)

So the first step of Stephen is correct, but the first step of Helen is not, you can not simplify the expression in that way.

now, we have that:

a*ln(x) = ln(x^a)

then we can write:

(4/3)*ln(2) = ln(2^(4/3))

and e^(ln(2^(4/3)) = 2^(4/3)

then we have:

e^((4/3)*ln(2)*e^(-1) = 2^(4/3)/e

now we can write this as:

The number of novels purchased was 9 novels.

Let the number of novels purchased be x and the number of magazines purchased be y.

Hence, \(x + y = 11.\)

Let the selling price of novels be a and that of magazines be b.

Therefore, \(ax + by = 20.\)

Similarly, given the price of magazines and novels as shown below:

\(a=  2\\b = 1\)

We can use the given equations above to find the number of novels purchased.

To find the value of x, we substitute the value of a and b into the equations,

\(ax + by = $20$2x + $1y \\= $20\)

We can also use the equation we found from \(x + y = 11,\) and solve for \(y:y = 11 - x\)

We can now substitute this value of y into the equation\(2x + 1y = 202x + 1(11 - x) \\= 201x \\=9x \\= 9 novels\)

Let:

x = Unknown number

The correct quadratic equation that can be used to determine the thickness of the frame, x, is: 2x² + 10x - 7 = 0, Therefore Option B is the right answer

Here's how we can get this equation:

We are given that the mirror and frame together have an area of 7 square feet. The mirror itself has an area of 2 x 3 = 6 square feet. So, the area of the frame is 7 - 6 = 1 square foot.

Let's assume that the width of the frame is x feet. Then the overall width of the mirror and frame becomes 2 + 2x, and the overall length becomes 3 + 2x. The area of the mirror and frame can be expressed as:

(2 + 2x)(3 + 2x) = 6 + x(10 + 4x)

We know that this expression equals 7, so we can set it equal to 7 and obtain the quadratic equation:

2x² + 10x - 7 = 0

Therefore, the correct quadratic equation is 2x² + 10x - 7 = 0.

B. 2 and OD. 15 are not possible lengths for the third side of the triangle.

To determine the possible values for the length of the third side of a triangle, we need to consider the triangle inequality theorem, which states that the sum of the lengths of any two sides of a triangle must be greater than the length of the third side.

Given that two sides have lengths 6 and 9, we can analyze the possibilities:

6 + 9 > x

x > 15 - The sum of the two known sides is greater than any possible third side.

6 + x > 9

x > 3 - The length of the unknown side must be greater than the difference between the two known sides.
