How do you tell the possible rational roots of a polynomial function? How do you test one of the possible rational roots to see if it is indeed a zero?

Answers

Answer 1

Step-by-step explanation:

To find the possible rational roots of a polynomial function, you can use the Rational Root Theorem. According to this theorem, if a rational number "p/q" is a root of a polynomial function, where p and q are integers, and q ≠ 0, then p must div ide the constant term of the polynomial and q must divide the leading coefficient of the polynomial.

To test if one of the possible rational roots is indeed a root (zero) of the polynomial, you can use the Synthetic Division method. In this method, you divide the polynomial by the linear factor (x - p/q) corresponding to the test root, and check if the remainder is zero. If the remainder is zero, then the test root is a zero (root) of the polynomial.

Suppose an object is thrown upward with initial velocity of 48 feet per second from a high of 120 feet. The height of the object t seconds after it is thrown is given by h(t)=-16t^2+48t+120. Find the average velocity from t=2 to t=4.
Type your answer as a number with no units.

Answers

The average velocity of the object from t = 2 and t = 4 is equal to - 48 feet per second.

How to calculate the average velocity of an object thrown upward

In this problem we find the case of an object thrown upward, whose height (h(t)), in feet, as a function of time (t), in seconds, is represented by a quadratic equation. We need to determine the average velocity (u) of the object by means of secant line formula:

u = [h(4) - h(2)] / (4 - 2)

Where:

h(4) - Height of the object at t = 4 s, in feet.h(2) - Height of the object at t = 2 s, in feet.

If we know that h(t) = - 16 · t² + 48 · t + 120, then the average velocity is:

t = 2

h(2) = - 16 · 2² + 48 · 2 + 120

h(2) = 152 ft

t = 4

h(4) = - 16 · 4² + 48 · 4 + 120

h(4) = 56 ft

u = (56 ft - 152 ft) / (4 s - 2 s)

u = - 48 ft / s

in a right triangle, a and b are the lengths of the legs and c is the length of the hypotenuse. if a 56 millimeters and c = 65 millimeters, what is b? if necessary, round to the nearest tenth.

Answers

Answer:

b = 33 millimeters.

Step-by-step explanation:

In a right triangle, the Pythagorean theorem states that the square of the length of the hypotenuse (c) is equal to the sum of the squares of the lengths of the legs (a and b). So, using a=56 and c=65, we can find b by solving the equation: 56^2 + b^2 = 65^2. This gives b = sqrt(1089) = 33 millimeters :)

What is the rate of change of Y= -10x+300

Answers

Answer: The given equation is Y = -10x + 300.

The rate of change of this equation refers to the rate at which Y changes as x changes. This is the same as the slope of the line represented by the equation.

The equation is in the form of y = mx + b, where m is the slope and b is the y-intercept. So, we can see that the slope of the line is -10. This means that for every one unit increase in x, y decreases by 10 units.

Therefore, the rate of change of Y with respect to X is -10.

assume the speed of vehicles along a stretch of i-10 has an approximately normal distribution with a mean of 71 mph and a standard deviation of 8 mph. what proportion of the vehicles would be going less than 50 mph?

Answers

The proportion of vehicles travelling less than 50 mph is 0.1587, as it is the area under the normal curve from 0 to 50 mph.

The speed of vehicles travelling along a stretch of I-10 is assumed to have an approximately normal distribution with a mean of 71 mph and a standard deviation of 8 mph. This means that the majority of vehicles will travel at speeds close to the mean, with fewer vehicles travelling at speeds significantly above or below the mean. To calculate the proportion of vehicles travelling less than 50 mph, we must calculate the area under the normal curve from 0 mph to 50 mph. This is done using a z-score, which is calculated by subtracting the mean from the value and dividing by the standard deviation. In this case, the z-score for 50 mph is -1.375. The area under the normal curve from 0 mph to -1.375 is 0.1587, which is the proportion of vehicles travelling less than 50 mph.

A pole is supported by two wires, one on each side, going in opposite directions. The wires are 14 feet and 17 feet long. If the wires are to be secured to the ground 22 feet from each other, what angle must the 14-foot long wire make with the ground. Solve using law of cosins and sins​

Answers

The angle that must the 14-foot long wire make with the ground = 50.6°

Consider the following diagram.

AC represents the pole.

AB represents the supporting wire of length 14 ft and AD is wire of length 17 ft.

The wires are to be secured to the ground 22 feet from each other.

BD = 22 ft

We need to find angle that must the 14-foot long wire make with the ground i.e., angle ACD

Using law of cosines,

c² = a² + b² - 2ab. cos(x)

where x = ∠ABD

c is the opposite side of angle x

a and b are adjacent sides of angle x

here,  c = 17, a = 14, and b = 22

Substitute these values in above formula,

17² = 14² + 22² - 2(14)(22). cos(x)

289 = 196 + 484 - 616 cos(x)

-391 = -616 cos(x)

cos(x) = (391/616)

x = arccos(391/616))

a ball is kicked such that its height (h) can be represented by the equation , where t represents time in seconds. how long does it take for the ball to reach its highest point, and how high is that maximum height?

Answers

The maximum height of the ball is 200 feet.

What do you mean by equation?

An expression can be used to solve for a single unknown value, for example, the equation 2x + 3 = 7 can be solved for x by subtracting 3 from both sides, giving us 2x = 4 and then dividing both sides by 2, giving us x = 2. In this example, x = 2 is the solution to the equation.

To find the time to the highest point, we need to find the time when the velocity of the ball is equal to zero. The velocity of the ball can be found by taking the derivative of the height equation with respect to time.

The derivative of h with respect to t is:

dh/dt = 32t + 64

Setting the derivative equal to zero and solving for t, we get:

0 = 32t + 64

-64 = 32t

t = -2

So, the time to the highest point is -2 seconds. However, since time cannot be negative in this context, we can say that it takes 2 seconds for the ball to reach its highest point.

To find the maximum height, we can substitute the time of 2 seconds back into the original height equation:

h = 16(2)^2 + 64(2) + 8

h = 64 + 128 + 8

h = 200

So, the maximum height of the ball is 200 feet.

The most correct answer is D ( 3,-2) . Because in the 2 equations above when you enter the value x= 3 in equation I and II, it produces y=-2.

Find the x and y values that satisfy the equation

In the question above, there are two equations.

y=-(½)x - ½ (eq I)

y=-(⅔)x (eq II)

To find which x and y values satisfy these two equations in options A,B,C,D, we have to substitute one by one to prove:

A.(-2, 3)

we substitute the value x=-2 into equation I

y=-(½)x - ½

y= -(½) (-2) -½

y=1-½

y= ½ ( This means that option A is not valid, because it should give y a value of 3)

B.(-1,0)

we substitute the value x=-1 into equation I

y=-(½)x - ½

y= -(½) (-1) -½

y= ½ - ½

y= 0

Then, we try to substitute the value x=-1 into equation II

y=-(⅔)x

y= -(⅔) (-1)

y= ⅔ ( This means option B is not valid, because it should result in y being 0)

C.(1, 2)

we substitute the value x=1 into equation I

y=-(½)x - ½

y= -(½) (1) -½

y= -½ - ½

y= -1 ( This means option C is not valid, because it should result in y being 2)

D. (3,-2)

we substitute the value x=3 into equation I

y=-(½)x - ½

y= -(½) (3) -½

y= -3/2- ½

y=-4/2

y= -2

Then, we try to substitute the value x=3 into equation II

y=-(⅔)x

y= -(⅔) (3)

in the circle above, point a is the center and the length of arc bcp is 2 5 of the circumference of the circle. what is the value of x ?

Answers

Step 1: Calculate the circumference of the circle.

Circumference = 2πr

Where 'r' is the radius of the circle.

Since we know the center of the circle is point A, we can calculate the radius of the circle by measuring the distance from point A to any point on the circumference.

Let's say we measure the distance from point A to point B.

Radius = AB = x

Step 2: Calculate the circumference of the circle.

Circumference = 2πx

Step 3: Calculate the length of arc bcp.

We know that the length of arc bcp is 2/5 of the circumference of the circle. So,

Length of arc bcp = (2/5) × (2πx)

Length of arc bcp = (4πx)/5

Step 4: Solve for x.

To solve for x, we will rearrange the equation:

(4πx)/5 = Length of arc bcp

5 × (4πx)/5 = 5 × Length of arc bcp

4πx = 5 × Length of arc bcp

4πx = 5 × (2/5) × (2πx)

4πx = 4πx

Since both sides of the equation are equal, x = x.

Therefore, the value of x is equal to itself.

The size of the wire is the dependent variable and the battery life is the independent variable.

What are dependent and independent variables?

In any equation, the variables that represent the input and output are referred to as independent and dependent variables, respectively.

Expression in maths is defined as the collection of numbers variables and functions by using signs like addition, subtraction, multiplication, and division.

Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.

By applying Algebraic fractions simplifying concept, it can conclude that the simplified expression is - (9p + 3) / q.

Algebraic fractions simplifying can be done by factoring the quantifier and denominator, then dividing by the common factors of the quantifier and denominator.

We have the following algebraic fraction:

((9p² - 1) / (pq - 2q)) / (1 - 3p) / (3p - 6)

To simplify this expression, we will do the following steps:

First, we apply the division rule: (a/b) / (c/d) = ad / bc:

    ((9p² - 1) / (pq - 2q)) / (1 - 3p) / (3p - 6)

⇔ ((9p² - 1) (3p - 6)) / ((pq - 2q) (1 - 3p))

Then we find the factors of (9p² - 1), that are (3p - 1) (3p + 1):

⇔ ((3p - 1) (3p + 1) (3p - 6)) / ((pq - 2q) (1 - 3p))

Factor other expressions that are not already factored in:

⇔ ((3p - 1) (3p + 1) 3 (p - 2)) / (q (p - 2) (1 - 3p))

Now we cancel the common factor (p - 2), so we have:

⇔ (3 (3p - 1) (3p + 1)) / (-q (3p - 1))

Then we cancel the common factor (3p -1), so we have:

⇔ (3 (3p + 1)) / -q

Finally, we expand the expression:

⇔ - (9p + 3) / q

Thus the simplified expression is - (9p + 3) / q.
