Since the zeros of the function are (3, 0) and (-5, 0), we can use the value of p = 3 and q = -5 in the factored form.
Also, in order to find the value of a, we can use the ordered pair (-1, 16) in the function, so we have:
\(\begin{gathered} y=a(x-3)(x+5)_{} \\ (-1,16)\colon \\ 16=a(-1-3)(-1+5) \\ 16=a(-4)(4) \\ 16=-16a \\ a=\frac{16}{-16} \\ a=-1 \end{gathered}\)So the factored form of the equation is:
\(y=-1(x-3)(x+5)\)Suppose that a point moves along some unknown curve y = f(x) in such a way that at each point (x,y) on the curve the tangent line has a slope \(\frac{x^{2}}{2}\) . Find an equation for the curve,given that it passes through (1,1).
\(y = \frac{x^3 +5}{6}\\\)
Step-by-step explanation:\(\frac{x^2}{2}\\\) is just the the derivative of \(f(x)\) since it it is the slope of the line tangent to the curve at \(x\). To find how \(f(x)\) is defined, we'll just take the anti-derivative of \(\frac{x^2}{2}\\\).
Recall:
\(\int x^n \mathrm{d}x = \frac{x^{n +1}}{n +1} &, &n \neq -1\\\)
Solving for \(f(x)\):
\(f(x) = \int \frac{x^2}{2} \mathrm{d}x \\ f(x) = \frac12 \int x^2 \mathrm{d}x \\ f(x) = \frac12 \cdot \frac{x^3}{3} \\ f(x) = \frac{x^3}{6} +C\)
We still have to solve for \(C\). Note that the point \((1,1)\) has to be on our graph so \(f(1) = 1\) or \(\frac{(1)^3}{6} +C = 1\\\).
Solving for \(C\):
\(\frac{(1)^3}{6} +C = 1 \\ \frac{1}{6} +C = 1 \\ C = 1 -\frac{1}{6} \\ C = \frac{6}{6} -\frac{1}{6} \\ C = \frac{5}{6}\)
We can finally write \(f(x) = \frac{x^3}{6} +\frac{5}{6}\\\) or \(f(x) = \frac{x^3 +5}{6}\\\). Since \(y = f(x)\), we can write it as \(y = \frac{x^3 +5}{6}\\\) as well.

The impact on Carns’s income from eliminating the Small Tools Division would be: Multiple Choice
The impact on Carns Company's income from eliminating the Small Tools Division would be a decrease of $1,209,000.
To determine the impact on Carns Company's income from eliminating the Small Tools Division, we need to consider the avoidable costs associated with the division.
The avoidable costs include all of the variable costs of the division and a portion of the fixed costs that are specifically related to the Small Tools Division. In this case, the variable costs of the division are $1,295,000, and $119,000 of the fixed costs are avoidable.
To calculate the impact on income, we subtract the avoidable costs from the loss reported by the division:
Impact on income = Loss - Avoidable costs
Impact on income = $205,000 - ($1,295,000 + $119,000)
Impact on income = $205,000 - $1,414,000
Impact on income = -$1,209,000
The negative sign indicates a decrease in income.

Answer:

Step-by-step explanation:
Find the missing angle and side measures of Delta*ABC , given that
m angle A = 50 deg , m angle C = 90 deg , and CB = 16
The missing angle is <B= 40 degree and missing side length is AB = 12.25 and AC = 19.068.
To find the missing angle and side measures of ΔABC, we can use the properties of a triangle.
Given:
∠A = 50°
∠C = 90°
CB = 16
We can start by finding the measure of ∠B:
∠A + ∠B + ∠C = 180° (Sum of angles in a triangle)
50° + ∠B + 90° = 180°
∠B + 140° = 180°
∠B = 180° - 140°
∠B = 40°
Now, using Sine law
CB/ sin A = AB / sin C
16 / sin 50 = AB / sin 90
16 / 0.766044 = AB
AB = 12.25
Again 12.25 = AC/ sin B
12.25 = AC / sin 40
AC = 19.068

en un parque hay una zona de columpios y una pista de patinaje que ocupa en total 5 quintos del espacio .si los columpios ocupan 2 septimos del parque . que fraccion del parque ocupa la pista de patinaje
Answer:
The rink occupies 69% of the whole park, approximately, which is equivalent to 280/408.Step-by-step explanation:
To solve this problem, we need to find the number which express the whole park.
Notice that the park is divided in two sections, one occupies 5/8 of the total, and the other occupies 2/7 of the total. So, the sum would be
\(\frac{5}{8}+\frac{2}{7}=\frac{35+16}{56} =\frac{51}{56}\)
Now we have the total space there, we need to divide 5/8 by 51/56, so
\(\frac{5}{8} \div \frac{51}{56}=\frac{5}{8} \times \frac{56}{51}=\frac{280}{408} \approx 0.69\)
Therefore, the rink occupies 69% of the whole park, approximately, which is equivalent to 280/408.
If (x -1) is a factor of the polynomial f(x) = 4x²- 4x² - x - K, where K is a Constant.
1. What is the Value of K?
2. What are the roots of the equation
Answer:
If (x-1) is a factor of the polynomial f(x) = 4x² - 4x² - x - K, then we know that (x-1) divides evenly into the polynomial, which means that the polynomial can be written as:
f(x) = (x-1)(ax + b)
where a and b are constants that we need to determine. We can use the distributive property to expand this expression and equate it with the original polynomial:
f(x) = (x-1)(ax + b) = 4x² - 4x - K
Expanding the left side of the equation, we get:
ax² + bx - ax - b = ax² - (a-b)x - b = 4x² - 4x - K
Now we can equate the coefficients of the like terms on both sides of the equation.
The coefficient of x^2 on the left side is a, and on the right side it is 4. Therefore, we have:
a = 4
The coefficient of x on the left side is b - a, and on the right side it is -4. Therefore, we have:
b - a = -4
Substituting a=4, we get:
b - 4 = -4
Solving for b, we get:
b = 0
So the polynomial can be written as:
f(x) = (x-1)(4x + 0) = 4x² - 4x
Therefore, K = 0.
To find the roots of the equation, we need to set f(x) = 0 and solve for x:
4x² - 4x = 0
Factor out 4x:
4x(x - 1) = 0
So the roots of the equation are x = 0 and x = 1.

Find the measures of angles a and b and of arc c Please
The measure of arc CD is equal to the measure of angle BCD, which is 240 degrees.
In the given diagram, we can see that angle ACD is a right angle, since it is formed by the radius AC and tangent CD at point C.
Therefore, angle BCD is equal to angle ACD, which is 90 degrees.
Since angle BCD is an exterior angle of triangle BCF, it is equal to the sum of the two remote interior angles, which are angles BFC and FCB.
Angle BFC is equal to angle ABC (since they are opposite angles), which is 60 degrees.
Similarly, angle FCB is equal to angle ACF, which is also 60 degrees.
Therefore, angle BCD is equal to angle BFC + angle FCB, which is 60 + 60 = 120 degrees.
Now, since arc CD is subtended by angle BCD, its measure is also equal to 120 degrees.
Hence, the measure of arc CD is 120 degrees.
Similarly, angles ACF and FCB are opposite angles in the cyclic quadrilateral AFCB, so they are supplementary. Therefore, angle FCB is equal to 180 - angle ACF,
Which is also 180 - 60 = 120 degrees.
Now we can apply the exterior angle theorem to find the measure of angle BCD. We have:
angle BCD = angle BFC + angle FCB
= 120 + 120
= 240 degrees
Finally, we can conclude that the measure of arc CD is equal to the measure of angle BCD, which is 240 degrees.

What are the points of the image of the line in Q4 after the dilation?
Note that the coordinates of the point A' after rotating 90 degrees clockwise about the point (0,1) are (3, -4). (Option B)
How is this so ?To rotate a point 90 degrees clockwise about a given point,we can follow these steps -
Translate the coordinates of the given point so that the center of rotation is at the origin. In this case,we subtract the coordinates of the center (0,1) from the coordinates of point A (5,4) to get (-5, 3).
Perform the rotation by swapping the x and y coordinates and changing the sign of the new x coordinate. In this case,we swap the x and y coordinates of (-5, 3) to get (3, -5).
Translate the coordinates back to their original position by adding the coordinates of the center (0,1) to the result from step 2. In this case, we add (0,1) to (3, -5) to get (3, -4).
Therefore, the coordinates of the point A' after rotating 90 degrees clockwise about the point (0,1) are (3, -4).
