Find the zeros of the function. f(x) = x^2 + 3x + 2
Answer:
This function returns a zero value when x is equal to negative one or negative two.
Step-by-step explanation:
We can solve this by factoring the function:
f(x) = x² + 3x + 2
= x(x + 1) + 2(x + 1)
= (x + 1)(x + 2)
So function equals zero when x = -1 or -2
Triangle ABC can be plotted at A (-14, 14), B (-8, 11) & C (-14, 5). Reflect Triangle ABC acro the y-axi. Next, rotate 180 degree counterclockwie about the origin. What i the ordered pair of C'' after the equence of tranformation?
The ordered pair of C'' after the sequence of transformation is (-14, -5)
Here we have know that ABC can be plotted at A (-14, 14), B (-8, 11) & C (-14, 5).
Here we all know that the y-axis reflection rule is written as,
=> (x, y) → (-x, y)
And the value of x coordinate flips in sign from positive to negative, or vice versa. Then the value of y coordinate stays the same.
Then the point is look like C(-14,5) will then reflect based on the following rule,
=> (x, y) → (x, y)
The transformed coordinates are look like,
=> (-14,5) ((-14),5)
=> (-14,5)→ (14,5)
Therefore, here we have point C' located at (14,5) after applying the y-axis reflection rule on point C.
Now, the next operation to do is is the 180 degree rotation.
And this can be clockwise or counterclockwise.
Then the rotation rule is written as
=> (x, y) → (-x,y)
Now, for this time both coordinates flip in sign.
Here we have know that this rule only works if the center of rotation is the origin.
Now, let us apply that rotation rule to C' to find where C" is located.
Then the rule can be written as, (x, y) → (-x,y)
=> (14,5)→ (-14, -5)

An engineer was asked to design a water sprinkler that will cover a field of area 100m2 that is in the shape of a sector of radius 15m. through what angle should the sprinkler rotate
The angle by which the sprinkler should rotate is 0.89 Radians or 50.93°.
The space inside the section of the circle formed by two radii and an arc is the sector's area. It is a small portion of the circle's total surface area.
Area of sector of circle (A) = \(\frac{1}{2} r^{2}x\)
where, A= 100 square yards,
r = 15 yards,

3. Consider a polar curve r =-2 sin θ (a) Sketch the curve with the given polar equation by first sketching the graph of r as a function of θ in Cartesian coordinates. (b) Sketch the graph of the same polar curve but by converting it in to the Carte- sian form. (c) Are the graphs from Part(a) and Part(b) are same or different? Why?
The polar curve r = -2 sin θ can be graphed by first plotting the graph of r as a function of θ in Cartesian coordinates. To do this, we can set r = y and θ = x, and then plot the resulting equation y = -2 sin x.
This graph will have the shape of a sinusoidal wave with peaks at y = 2 and troughs at y = -2.
To sketch the same polar curve in Cartesian form, we can use the conversion equations x = r cos θ and y = r sin θ. Substituting in the given polar equation, we get x = -2 sin θ cos θ and y = -2 sin² θ. Simplifying these equations, we get x = -sin 2θ and y = -2/3 (1-cos² θ). This graph will have the shape of a four-petal rose.
The graphs from Part (a) and Part (b) are different because they represent different equations. Part (a) is the graph of y = -2 sin x, which is a sinusoidal wave. Part (b) is the graph of a four-petal rose. However, both graphs share some similarities in terms of their shape and symmetry. They are both symmetrical about the origin and have a repeating pattern.
In conclusion, we can sketch a polar curve by first graphing r as a function of θ in Cartesian coordinates and then converting it to Cartesian form. The resulting graphs may look different, but they often share similar patterns and symmetries.

find the formula for logistic growth using the given information. (use t as your variable. round your parameters to three decimal places.) the r value is 0.013 per year, the carrying capacity is 2392, and the initial population is 127.
Substituting the given values into the formula, we get logistic growth as
\(P(t) = 2392 / (1 + 18.748 * e^{(-0.013 * t)})\)
What is logistic growth?A pattern of population expansion known as logistic growth sees population growth begin slowly, pick up speed, then slow to a stop as resources run out. It can be shown as an S-shaped curve or a logistic function.
The formula for logistic growth can be expressed as:
\(P(t) = K / (1 + A * e^{(-r * t)})\)
where:
P(t) is the population at time t,
K is the carrying capacity,
A = (K - P₀) / P₀,
P₀ is the initial population,
r is the growth rate per unit of time, and
e is the base of the natural logarithm (approximately 2.71828).
Given the information you provided:
r = 0.013 (per year)
K = 2392
P₀ = 127
First, let's calculate the value of A:
A = (K - P₀) / P₀ = (2392 - 127) / 127 = 18.748
Now, substituting the given values into the formula, we get:
\(P(t) = 2392 / (1 + 18.748 * e^{(-0.013 * t)})\)

Maribelle uses x yards of material to make a quilt. A customer requests 5 quilts that are 20% larger than the normal pattern. Write an expression to represent the total yards of material needed for the requested quilts in two different ways?
Answer:
i. 5(x + 0.2x) yards
ii. 6x yards
Step-by-step explanation:
Since the requested quilts are 20% larger than the normal pattern, then;
20% of x = 0.2 x
Thus,the yards of material to make each of the requested quilts increased by 0.2x yards.
So that;
To make one of the requested quilt, the yards required = x + 0.2x
For 5 requested quilts, the total yards required = 5(x + 0.2x)
Total yards of material for the requested quilts is 5(x + 0.2x).
Also,
5(x + 0.2x) = 5x + 5(0.2x)
= 5x + x
= 6x
Thus, the total yards required is 5(x + 0.2x) or 6x.

Suppose Q and R are independent events. Find P(Q and R). P(Q)=0.37,P(R)=0.24
To find P(Q and R), we can use the formula: P(Q and R) = P(Q) × P(R) Since the events Q and R are independent, we can multiply the probabilities of each event to find the probability of both events occurring together. P(Q) = 0.37P(R) = 0.24P(Q and R) = P(Q) × P(R) = 0.37 × 0.24 = 0.0888.
Therefore, the probability of both Q and R occurring together is 0.0888. Long Answer:Independent events:In probability theory, two events are independent if the occurrence of one does not affect the probability of the occurrence of the other. Two events A and B are independent if the probability of A and B occurring together is equal to the product of the probabilities of A and B occurring separately. Mathematically,P(A and B) = P(A) × P(B) Suppose Q and R are independent events. Find P(Q and R).
We can use the formula: P(Q and R) = P(Q) × P(R) Since the events Q and R are independent, we can multiply the probabilities of each event to find the probability of both events occurring together. P(Q) = 0.37P
(R) = 0.24
P(Q and R) = P(Q) × P(R)
= 0.37 × 0.24
= 0.0888
Therefore, the probability of both Q and R occurring together is 0.0888. Hence, P(Q and R) = 0.0888. In probability theory, independent events are the events that are not dependent on each other. It means the probability of one event occurring does not affect the probability of the other event occurring.

The speed of the faster cyclist is 14\ miles/hr.
What is speed?
It is the average distance coverd in unit time. It is also defined as the rate of change of distance with respect to time.
Since the speed of the first cyclist is double than the second cyclist hence, the first cyclist will cover the double distance than the second cyclist. Consider the first cyclist covers 2s distance and first cyclist covers s distance. The sum of these two distances should be 42 miles. Hence,
\(2s+s=42\\3s=42\\s=14\)
Now, distance coverd by the first cyclist is \(2s=2\times 14\\=28 \ $miles\).
Now, both the cyclists meet after 2 hr hence, time taken by the first cyclist is 2 hr.
\(Speed=\frac{Total\ distance}{Total\ time}\\=28\ miles/2 \ hr\\=14\ miles/hr\)
