Answer:

False

Step-by-step explanation:

Answer:

(A)All real solutions

Step-by-step explanation:

Given the function g(x) shown on the graph

One of the points of the parabola is  (-3.5, 0).

The point x=-3.5 is one of the solution of the parabola since it intersects the x-axis at that point.

The other point of intersection is on the positive side between 0 and 1.

Therefore, g(x) has two solutions: One negative real number and one positive real  number.

Therefore, g(x) has all real solutions.

The correct option is A.

Answer:

All solutions that lie on g(x)

Answer:

x = 11.25

Step-by-step explanation:

-6 = 0.8x - 15

Add 15 to both sides;

-6 + 15 = 0.8x - 15 + 15

9 = 0.8x

Divide both sides by 0.8;

x = 11.25

Answer:

Divide both sides by 0.8;

x = 11.25

Step-by-step explanation:

To find the value of P(-2), we need to determine the polynomial function P(x) of degree 3 that satisfies the given derivatives. The value of P(-2) is 156.

The first derivative, p'(x), gives us information about the slope of the polynomial at each point. Since p'(1) = 45, we know that the slope of P(x) at x = 1 is 45.

The second derivative, p''(x), represents the rate at which the slope of the polynomial is changing. Given that p''(1) = 48, we can conclude that the slope of P(x) is increasing at x = 1.

The third derivative, p'''(x), provides information about the curvature of the polynomial. With p'''(1) = 24, we determine that the polynomial is concave up at x = 1.

Using these derivatives, we can construct a polynomial function P(x) that satisfies the given conditions. Integrating p'(x) gives us p(x), and integrating p(x) gives us P(x).

Since we are given p(1) = 75, we can determine the constant term of P(x). Integrating p'(x) = 45, we find p(x) = 45x + C. Evaluating p(1) = 75, we get 45(1) + C = 75, which gives us C = 30.

Therefore, p(x) = 45x + 30, and integrating p(x) gives us P(x) = (45/2)x^2 + 30x + D, where D is a constant term.

To find D, we can use p''(x). Integrating p''(x) = 48, we obtain p'(x) = 48x + K, where K is another constant term.

Using p'(1) = 45, we have 48(1) + K = 45, which leads to K = -3.

Now we have p'(x) = 48x - 3. Integrating p'(x), we get p(x) = 24x^2 - 3x + L, where L is a constant term.

Using p(1) = 75, we find 24(1)^2 - 3(1) + L = 75, which gives L = 54.

Thus, p(x) = 24x^2 - 3x + 54.

Finally, to find P(-2), we substitute -2 into the polynomial function P(x):

P(-2) = 24(-2)^2 - 3(-2) + 54

= 24(4) + 6 + 54

= 96 + 6 + 54

= 156.

Therefore, the value of P(-2) is 156.

The value of m using completing the square method is 15.95 or -3 .95

Completing the square method is one of the methods to find the roots of the given quadratic equation.

Solving ; m² -12m -16 = 47

collecting like terms

m² -.12m = 47 + 16

m² -12m = 63

dividing the coefficient of x by 2 and adding it to both sides.

m² - 12m + ( -6)² = 63 + 6²

(m-6)² = 99

Step-by-step explanation:

sorry i need to run but thats one

The conditions on the positive numbers a, b, c, and d that will guarantee that every difference at every step in the expansion (a-b)(c-d) results in a positive number are:

1. a > b
2. c > d

This will ensure that the difference between a and b, as well as the difference between c and d, are both positive numbers. Therefore, when these two differences are multiplied together in the expansion (a-b)(c-d), the result will be a positive number.

For example, if a=5, b=2, c=8, and d=3, then the expansion (a-b)(c-d) will result in a positive number:

(5-2)(8-3) = (3)(5) = 15

As long as the conditions a > b and c > d are met, the expansion (a-b)(c-d) will result in a positive number.

The three conditions for a function to be continuous at a point x=a are:

a) The function is defined at x=a.

b) The limit of the function as x approaches a exists.

c) The limit of the function as x approaches a is equal to the value of the function at x=a.

The continuity of a function can be analyzed by observing its graph. However, as the graph is not provided, a specific discussion about its continuity cannot be made without further information. It is necessary to examine the behavior of the function around the point in question and determine if the three conditions for continuity are satisfied.

The function f(x) = { *** is not defined in the question. In order to discuss its continuity, the function needs to be provided or described. Without the specific form of the function, it is impossible to analyze its continuity. Different functions can exhibit different behaviors with respect to continuity, so additional information is required to determine whether or not the function is continuous at a particular point or interval.

Answer:

i think y=3/4x-4.2

Step-by-step explanation:

Answer:   1/2 |x| = -3?

Step-by-step explanation:

The equation in slope-intercept form for the line is y = -3/2x + 5.

We have,

In slope-intercept form,

The equation of a line is written as y = mx + b, where m represents the slope of the line and b represents the y-intercept (the point where the line crosses the y-axis).

Given that the slope is -3/2 and the y-intercept is 5, we can substitute these values into the equation to obtain:

y = -3/2x + 5.

This equation tells us that for every increase of 1 unit in the x-coordinate, the y-coordinate decreases by 3/2 units.

The y-intercept of 5 indicates that the line passes through the point (0, 5).

Thus,

The equation in slope-intercept form for the line is y = -3/2x + 5.

Answer:

The answer to your problem is, There are total 55 counters out of which 11 are green and 44 are other color.

Step-by-step explanation:

This is a ratio and proportion question. There are c amount of counters in the box

same ratio as in the box

Green : total

4:         20

11:          x

Use cross product rule

x * 4= 20 *11

x= 20*11/4

x= 55. Which is the answer.

So there are total 55 counters out of which 11 are green and 44 are other color. Benedict take 20 counters out of which 4 are green. 

Thus the answer to your problem is, There are total 55 counters out of which 11 are green and 44 are other color.

The amount loaned at 5% interest is $7,500. Let's say the bank loaned out x dollars. The amount loaned at 5% interest is 0.05x dollars, and the amount loaned at 10% interest is 0.10x dollars.

We know that the total interest received in one year was y dollars. We can set up the following equation to represent this information:

0.05x + 0.10(x - 0.05x) = y

Simplifying the right side of this equation, we get:

0.05x + 0.10x - 0.05x = y

0.05x = y

Dividing both sides of this equation by 0.05, we get:

x = y / 0.05

x = 20y

We are given that the total interest received was $y = $1,500. Plugging this value into the equation, we get:

x = 20(1,500)

x = $30,000

Therefore, the amount loaned at 5% interest is $30,000 / 2 = $15,000. However, we are asked for the amount loaned at 5% interest, not 10% interest. So, we need to divide this amount by 2:

$15,000 / 2 = $7,500

Therefore, the amount loaned at 5% interest is $7,500.

While it is true that the general solution of a 2nd-order ODE of the form y''=c is given by y(t)=c/2*t^2 +bt+1, not all solutions are parabolas. Parabolas are a specific type of quadratic function with a constant value of a, which determines the curvature. In this general solution, 'a' is represented by c/2, and it can take any real value. So, although the solutions are quadratic functions, they are not necessarily parabolas.

Answer: Accounting profit=$90,000 and Economic profit loss= $28,500

Step-by-step explanation:

Accounting profit = Total revenue - Explicit costs Accounting profit = ($65 × 4,000) - ($50,000 + $120,000) Accounting profit = $260,000 - $170,000 Accounting profit = $90,000

Economic profit = Total revenue - (Explicit costs + Implicit costs) Economic profit = ($65 × 4,000) - ($50,000 + $120,000 + Forgone interest on savings + Forgone wages) Economic profit = ($65 × 4,000) - [$50,000 + $120,000 + (0.06 x $25,000) + $60,000] Economic profit (loss) = $28,500

Step-by-step explanation:

2x + 4y = 48

5x + 2y = 64

2x + 4y = 48

10x + 4y = 128

( 10x - 2x ) + ( 4y - 4y ) = ( 128 - 48 )

8x = 80

x = 10

Answer:

t = -b 2a = -120/(-32) = 3.75 The height of the rocket is a maximum 3.75 seconds after its launch. To find the height we only need to plug into the model: s(3.75) = -16(3.752) + 120(3.75) + 80 = 305 The maximum height of the rocket is 305 feet.

Step-by-step explanation:

The maximum value of graph of function is (3.75,225).

We consider, the equation is y=a(x-0)(x-7.5)

Now, when x=6 and y = 144

144=6a(-1.5)

⇒a= - 144/9

⇒a= -16

Now,  y= -16(x-0)(x-7.5)

⇒ y= -16\(x^{2}\)+120x

∴ x = -b/2a = -120/(-32) = 3.75

When x=3.75, then the value of y is maximum.

∴ \(y_{max}\) = \(-16(3.75)^{2}+120*3.75\)

          = 225

Hence, the maximum value of y is 225.

So, the required co-ordinate is (3.75,225).
