A) a-b=1
B) -b+c=1
C) a+b+c=1
D) a-b+c=1

Please help ;(

Answers

The answer is D cause you are given that the polynomial y=ax^+bx+c has the value y=1 a+x= -1. It means that (substitute this value of x= -1 into the polynomial) 1=y=a×(-1)+c =a*1-b+c=a-b+c.
again:a-b+c=1

The correct option will be "option D".

It is given that in the x-y plane, parabola with equation y=ax² + bx + c , passes through point (-1,1).

We have to check which equation is most suitable.

What is parabola ?

The graph of a quadratic equation in two variables (y=ax² + bx + c) is called a parabola.

Parabola has the equation ,

y = ax² + bx + c --------- Equation (1)

At point (−1, 1)

x = -1 and y = 1

Substitute the values of x and y in the equation (1).

i.e., y = ax² + bx + c

1 = a × (-1)² + b× (-1) + c

1 = a × (1) - b + c

1 = a - b + c

Thus, in x-y plane at point (1,-1) , equation will be , a - b + c = 1.

How do you verify that a hexagon formed by A=(0,0), B=(2,1), C=(3,3), D=(2,5), E=(0,4) and F=(-1,2) is equiangular? (I already know that it is equilateral)

Answers

The solution is attached. This is the only way I could verify if it is equiangular.

Final answer:

To verify that the hexagon is equiangular, calculate the slopes and angles of all sides using the coordinates of the vertices.

Explanation:

To verify that a hexagon is equiangular, we need to show that all interior angles of the hexagon are congruent. We can calculate the angles using the coordinates of the vertices A, B, C, D, E, and F.

Calculate the slope of each side of the hexagon. For example, for side AB with points A(0,0) and B(2,1), the slope is (1-0)/(2-0) = 1/2.Use the slope to find the angle using the formula arctan(slope). For side AB, the angle is arctan(1/2) = 26.57 degrees.Repeat steps 1 and 2 for all sides of the hexagon.If all six angles are equal, then the hexagon is equiangular.

Please Help Fast!!!!

Answers

The y-intercept (point where x, or time equals zero), is 12 miles. This means that when observation of the bird began at time t=0, it was already away from its nest. Based on the rest the graph, one can infer that the bird has a very large range (travels far from her nest) and spends a great deal of time away from her nest.

To find the average rate of change of the function, take the change in y between x=1 and x=3 and divide by 2.
(36 - 20) / 2 = 16/2 = 8 miles / hour .

The domain of the function is the range of x for which y is a real number. We see in the chart provided that the bird travels 8 miles every hour.

How many hours will it take to travel 172 miles from the nest? The bird started at 12, so let's so how long it takes to travel 172 - 12 = 160 miles, moving at a rate of 8 miles/hour.
160 miles / 8mph = 20 hours
The domain of the function, the time range in which the bird travels 172 miles from the nest, will be 0 ≤ x ≤ 20

round 999.999 to the nearest tenth

Answers

999.9

to the left of the point you start with tenths then hundredths and so on

Answer: 1000
Reasoning:
For the number 999.999, the 0.9 is the tenth's digit.
Since the next number is 5 or greater, we round the 0.9 up. Now 0.9 rounded up is 1, so that takes away the decimals and adds one to the ones place value.
Since we are adding 1 to 9, it becomes 10, meaning the following 9 becomes a ten as well.
All said and done, it becomes 1000 from the rounding.

Answer:

x = -2/13

Step-by-step explanation:

This is a first degree polynomial. To solve it, you need to follow these steps:

Step 1: Equate the polynomial to zero

7x + 7 + 6x - 9 = 0

Step 2: Separate all numbers that have variable "x" on one side of equality and real numbers on the other side

7x + 6x + 7-9

Note: Remember that if you are going to pass a number from side to side the equality is reversed.

Step 3: Add Both Sides

Step 4: Isolate the "x" Variable

Given that f(a+b)= f(a) + f(b) and f(x) is always positive, what os the value of f(0)?

Answers

This is a strange question, and f(x) may not even exist. Why do I say that? Well..

[1] We know that f(a+b) = f(a) + f(b). Therefore, f(0+0) = f(0) + f(0). In other words, f(0) = f(0) + f(0). Subtracting, we see, f(0) - f(0) = f(0) or 0 = f(0).

[2] So, what's the problem? We found the answer, f(0) = 0, right? Maybe, but the second rule says that f(x) is always positive. However, f(0) = 0 is not positive!

Since there is a contradiction, we must either conclude that the single value f(0) does not exist, or that the entire function f(x) does not exist.

To fix this, we could instead say that "f(x) is always nonnegative" and then we would be safe.

How do you write 180% as a fraction or mixed number in simplest form?

Answers

180% would be written as 1 4/5 in simplest form

Final answer:

To write 180% as a fraction or mixed number in simplest form, convert the percent to a fraction with a denominator of 100 and simplify the fraction. The simplified fraction is 9/5 or the mixed number is 1 and 4/5.

Explanation:

To convert a percent to a fraction or mixed number in simplest form, we need to write the percent as a fraction with a denominator of 100 and then simplify it. In this case, 180% can be written as 180/100. To simplify, we divide both the numerator and denominator by their greatest common divisor, which is 20. So, the simplified fraction is 9/5. This fraction can also be expressed as a mixed number by dividing the numerator by the denominator. Since 9 is greater than 5, the mixed number is 1 and 4/5.

what transformation has changed the parent function f(x) =log3x to its new appearance shown in the graph below

Answers

The parent function f(x) = log_3(x) has two important values that we can find.

log_3(1) asks "3^? = 1," which we know is 0. So, log_3(1) = 0, which means (1,0) is a point on the graph for the parent function.

log_3(3) asks "3^? = 3" which we know is 1. So, log_3(3) = 1, which means (3,1) is a point on the graph for the parent function.

Now, we look at the graph they gave us and we see that our two points have moved upward 2 units. Now, (1,2) and (3,3). The transformation appears to be f(x) + 2, as you have selected.

Find the average value of f over region
d. f(x, y) = 4x sin(y), d is enclosed by the curves y = 0, y = x2, and x = 7.

Answers

Final answer:

The question involves finding the average value of function f(x, y) = 4x sin(y) over a particular region. This is done using a double integral to integrate the function over the region and divide by the area of that region. The area of the region is determined using the given boundaries.

Explanation:

The subject of this question is calculus, specifically dealing with a double integral to find the average value of a function over the specified region. The given function is f(x, y) = 4x sin(y), and the region d is enclosed by the curves y = 0, y = x^2, and x = 7.

To find the average value of function f over the region d, you should use the formula for the average value of a function of two variables. This is given by: Avg = (1/Area(D)) ∫∫_D f(x, y) dA

Before we can use this formula, we need to find the area of region D. This can be obtained as a simple integral from the given boundaries: Area(D) = ∫ from 0 to 7 dx ∫ from 0 to x^2 dy = ∫ from 0 to 7 x^2 dx = [x^3/3]_0^7 = 343/3

We can then proceed with the double integration by applying the appropriate limits. This is a more complex process that requires substitutions and careful calculation. After evaluating the average value, you should get a numerical solution.
