Answer:

(6,0)

Step-by-step explanation:

Solving a system of equations is finding where 2 (or more) lines intersect.

Graph the lines:

y = x/6 - 1

and

y = -2/3x + 4

(linked)

Look at where they intersect (meet).

(6,0)

Option D is correct that is BC = 2

A line is a perfectly straight, one-dimensional shape that is endlessly long and thin in both directions.

She tells us that AC is 15, and we may deduce that AC equals AB plus BC from the figure.

AC Equals AB plus BC.

AB=4X+1, BC=2X-4, and AC=15

15 = 4X +1 + 2X- 4

15 = 6X - 3

18 = 6X

X = 3

We now know that 2X - 4

2(3) - 4 = 2 since we have X = 3.

BC = 2.

The volume of the crater is 64800000 m³

From the question, we are to determine the volume of the crater.

From the given information,

d = 2∛(V/0.3)

To determine the volume,

First, we will solve for V in the equation

d = 2∛(V/0.3)

Divide both sides by 2

d/2 = ∛(V/0.3)

Take the cube of both sides

(d/2)³ = V/0.3

Then,

V = 0.3(d/2)³

Now, substitute the value of the diameter

d = 1200m

Then,

V = 0.3(1200/2)³

V = 0.3(600)³

V = 64800000 m³

Hence, the volume is 64800000 m³

The number 25209 rounded to the largest place value is 30000.

Every digit in a number has a place value, which is a numerical value determined by the digit's position.

Step 1: First, decide which location value has the highest worth.

The number that is farthest to the left has the highest place value.

Providing the value is not zero.

In the number 25209,

2 is the largest place value.

Step 2: Next, take a look at the number that is closest to the largest place value.

The greatest place value remains the same if the number is 0, 1, 2, 3, or 4.

The highest place value increases by one if the number to the right is a 5, 6, 7, or 9.

We have number 5 to the right of 2.

For given functions f and g, the sum of the areas of the enclosed regions is 2.004 sq. units. and the sum of the volumes of the enclosed regions is 1.283 cubic units

In this question we have been given two functions f and g defined by

f(x) = 1 + x + e^x^2 - 2x and g(x) = x^4 - 6.5x^2 + 6x + 2.

There are two regions on the interval 0 x 2 which are enclosed / and g. We need to find the sum of the areas of the enclosed regions and the sum of the volumes of the enclosed regions.

The graph of functions is as shown below.

We can observe that the graphs of y = f(x) and y = g(x) intersect in the first quadrant at the points (0, 2), (2, 4), and (A, B) = (1.032832, 2.401108).

The sum of the areas of the enclosed regions is given by

A = ∫[0-A] (g(x) - f(x)) dx + ∫[A - 2] (f(x) - g(x)) dx

A = 0.997427 +1.006919

A = 2.004

And the sum of the volumes of the enclosed regions is given by

Volume V =∫[0-4]  [[ƒ(x) − g(x)]² dx

V = ∫[0-4] [1 + x + e^x^2 - 2x - x^4 + 6.5x^2 - 6x - 2]^2 dx

V = 1.283

it changed the sign in the second to the third term，so,it was one root

[tex]-x^{3} +5x^{2} +3x+7[/tex]

Change the coefficients of odd items, and the signs of the first to second items change, so there is also a root.

Answer:

Step-by-step explanation:

Descartes' Rule of Signs tells us the maximum number of positive and negative real roots in a polynomial function.

Positive root case

[tex]\begin{aligned}p(x)&=(x)^3+5(x)^2-3(x)+7\\ &=+x^3+5x^2-3x+7\end{aligned}[/tex]

Check the signs of the coefficients. As there are 2 sign changes, the maximum possible number of positive roots is 2.

However, as some pairs of roots may be complex, count down by two's to find the complete list of the possible number of roots.

So there may be as many as 2 real roots or there might also be no real roots (zero).

Negative root case

[tex]\begin{aligned}p(-x)&=(-x)^3+5(-x)^2-3(-x)+7\\&=-x^3+5x^2+3x+7\end{aligned}[/tex]

Check the signs of the coefficients.  As there is one sign change, the maximum possible number of negative roots is 1.  We can't count down by two's since this would give us a negative number. Therefore, there is exactly 1 negative root.

Note:  There is one real negative root of the given function at x ≈ -5.74 and two complex roots at x = 0.37 + 1.04i  and  x = 0.37 - 1.04i.

Simplifying the given expression,

→ 1 2/5m - 3/5(2/5m + 1)

→ (7/5)m - 3/5(2/5m + 1)

→ (7/5)m - (6/25)m - (3/5)

→ (35/25)m - (6/25)m - (3/5)

→ ((35 - 6)/25)m - (3/5)

→ (29/25)m - (3/5)

→ (29m - 15)/25

The Angle ∠MTU from the figure is 65°

The study of shapes and their measurements falls under the umbrella of geometry, a subfield of mathematics. It also emphasizes how the shapes are arranged in relation to one another and their spatial characteristics. We are aware that geometry is divided into 2D and 3D categories. All geometrical shapes are first created by the intersection of points, lines, rays, and plane surfaces. The distance measured between two lines is referred to as a "Angle" when the rays or lines converge at a single point.

Given,

∠STM=31X-3;

∠MTU=20X+5;

∠STU=155°;

From the figure we can say that

∠STU= ∠STM+∠MTU;

⇒ 155=31x-3+20x+5;

⇒155=51x+2;

The probability of the archer hitting her target is 83%. This means that for each shot she takes, the probability of her hitting her target is 0.83. Since she has 20 shots to take, the expected number of targets hit is 20 x 0.83, which is 16.6.

The mean of x, which is the number of targets hit, is therefore 16.6. This can be calculated by taking the probability of success (0.83) multiplied by the number of trials (20), which gives the expected value of 16.6.

The number of desired outcomes divided by the total number of outcomes yields a probability.

We are attempting to determine the likelihood, out of 10, that the first chip will be white and the second won't be green while assuming that one chip is white and two are green.

1/10 of the time, the initial chip will be white. If the first chip is white, there is a 7/9 chance that the second chip will be a color other than green. The desired probability is therefore provided by:

Ten chips are present.

white 1

red 4

green 2

Blue 3

the likelihood of selecting the W chip is one in ten, or 0.10

There are now only 9 chips left (the first chip was not replaced)

Selecting a non-green chip has a probability of (9-2)/9 = 7/9 = 0.7777.

you multiply the two probabilities to obtain the overall probability at this point.
