(PLEASE HURRY!) A table giving various values of linear functions f(x) and g(x) is shown below. What is the solution to the system?

Answers

Answer:

  A.  (2, 1)

Step-by-step explanation:

You want the solution to the system of equations represented by the given table and graph.

Solution

When we are given two functions and asked for "the solution to the system", we generally mean the value of x that satisfies f(x) = g(x). That will be represented on a graph as the point (x, f(x)), or (x, g(x)), where the function graphs intersect.

Table

When you're looking for the solution in a table, you look for the row of the table where the value of f(x) is the same as the value of g(x). For the given table, we see that f(x) = g(x) = 1 on the last row of the table, where x=2. This means the solution is ...

  (x, f(x)) = (2, 1)

Mary Jo spends $2,300 to buy stock in two companies. She pays $19 a share to one of the companies and $24 a share to the other. If she ends up with a total of 100 shares, how many shares did she buy at $19 a share and how many did she buy at $24 a share?
She bought ____ shares at $19 and ___ shares at $24.

Answers

Answer:

Mary Jo bought 20 shares at $19 a share and 80 shares at $24 a share.

Step-by-step explanation:

Let's use algebra to solve the problem. Let x be the number of shares Mary Jo buys at $19 a share, and y be the number of shares she buys at $24 a share.

We know that Mary Jo spends a total of $2,300, so we can write the equation:

19x + 24y = 2300

We also know that she ends up with a total of 100 shares, so we can write the equation:

x + y = 100

Now we have two equations with two variables, which we can solve using substitution or elimination.

Let's use substitution. Solve the second equation for x:

x = 100 - y

Substitute this expression for x in the first equation:

19(100 - y) + 24y = 2300

Simplify and solve for y:

1900 - 19y + 24y = 2300

5y = 400

y = 80

So Mary Jo bought 80 shares at $24 a share.

To find the number of shares she bought at $19 a share, substitute y = 80 in the second equation:

x + 80 = 100

x = 20

Therefore, Mary Jo bought 20 shares at $19 a share.

In summary, Mary Jo bought 20 shares at $19 a share and 80 shares at $24 a share.

A sealed, inflated balloon is placed into a flask of liquid nitrogen at a temperature of 77 k. The ballon begins to shrink and shrivel up. Use gas particle motion to explain why.

Answers

This causes the volume of the balloon to decrease, leading to an increase in the number of collisions between gas particles and the inside surface of the balloon, and causing the balloon to shrink and shrivel up.

What is temperature?

Temperature is a measure of the average kinetic energy of the particles in a substance or system. In other words, it is a measure of how hot or cold something is relative to a standard reference point. The SI unit of temperature is the kelvin (K), but temperature is often measured in degrees Celsius (°C) or Fahrenheit (°F) in everyday life. Temperature plays a crucial role in many natural and man-made processes, and is a key factor in determining the behavior of matter at different states.

Here,

When a sealed, inflated balloon is placed into a flask of liquid nitrogen at a temperature of 77 K, the gas particles inside the balloon lose thermal energy and slow down. As the temperature drops, the average kinetic energy of the gas particles decreases, causing them to move slower and collide less frequently. This results in a decrease in pressure inside the balloon.

According to the Ideal Gas Law, PV = nRT, where P is the pressure of the gas, V is its volume, n is the number of moles of gas, R is the gas constant, and T is the temperature in Kelvin. As the pressure inside the balloon decreases, its volume also decreases, since the number of moles of gas and the gas constant remain constant.

Since the balloon is sealed, the gas particles cannot escape, so they continue to collide with each other and the inside surface of the balloon. As the volume of the balloon decreases, the gas particles become more crowded, increasing the number of collisions between them. This leads to a decrease in the distance between the gas particles and the inside surface of the balloon, causing the balloon to shrink and shrivel up.

In summary, when a sealed, inflated balloon is placed into a flask of liquid nitrogen at a temperature of 77 K, the gas particles inside the balloon lose thermal energy, slow down, and collide less frequently, resulting in a decrease in pressure inside the balloon.

What is the angle of elevation when little Judy looks at her red balloon?

Answers

The answer of the given question is (3) the length of the run of the Mighty Drop ski slope is approximately 181.8 feet. (4) the angle of elevation when little Judy looks at her red balloon is approximately 82.7°.

What is Slope?

A slope typically refers to the angle of an incline or ramp, or the ratio of vertical change to horizontal change of a straight line or curve on a graph. For an incline or ramp, the slope is the angle between the surface and the horizontal plane. It is defined as the ratio of the vertical rise to the horizontal run of the ramp.

In the context of a graph, slope refers to the steepness of a line or curve. It is defined as the ratio of the vertical change (rise) to the horizontal change (run) between any two points on the line or curve. The slope of a line can be positive (if the line goes up from left to right), negative (if the line goes down from left to right), or zero (if the line is horizontal).

(3) . To solve for the length of the run of the Mighty Drop ski slope, we can use the trigonometric function tangent, which relates angle of elevation to ratio of opposite and adjacent sides of right triangle.

Let x be the length of the run. Then we have:

tangent(75°) = opposite/adjacent

tangent(75°) = 800/x

Solving for x, we get:

x = 800 / tangent(75°)

x ≈ 181.8 feet

Therefore, the length of the run of the Mighty Drop ski slope is approximately 181.8 feet.

(4) . To solve for the angle of elevation when little Judy looks at her red balloon, we can use the trigonometric function arctangent.

Let θ be the angle of elevation. Then we have:

tangent(θ) = opposite/adjacent

tangent(θ) = 2240/350

Taking the arctangent on  both sides, we will get:

θ = arctangent(2240/350)

θ ≈ 82.7°

Therefore, the angle of elevation when little Judy looks at her red balloon is approximately 82.7°.

Using the geometric distribution formula, what is the probability that this player misses his first free throw, but makes the second one? Answer choices are rounded to the hundredths place.

Answers

If a basketball player has a 70% accuracy rate for making free throws. The probability that this player misses his first free throw, but makes the second one is 0.21.

How to find the probability?

The probability of making a free throw is 0.7, so the probability of missing a free throw is 0.3.

Let X be the number of trials (free throws) until the first success (a made free throw). Since we want to know the probability of missing the first free throw and making the second one, we want to find P(X = 2).

Using the geometric distribution formula, we have:

P(X = 2) = (1 - p)^(k-1) * p

where:

p is the probability of success (making a free throw)

k is the number of trials (2 in this case), and (1 - p)^(k-1) is the probability of having k-1 failures (missing the first free throw) followed by one success (making the second free throw).

Plugging in the values, we get:

P(X = 2) = (1 - 0.7)^(2-1) * 0.7

= 0.3 * 0.7

= 0.21

Therefore, the probability  is 0.21 (rounded to the hundredths place).

Tan^2a-cosec^2a+1=0 value of pie

the solutions for a are:

a = n×π, π/4, or 7π/4, where n is any integer.

define integer

An integer is a whole number that can be positive, negative, or zero, but does not include fractions or decimals.

tan²(a) - csc²(a) + 1 = 0

tan²(a) - (1/sin²(a)) + 1 = 0

(tan²(a)sin²(a) - 1 + sin²(a))/sin²(a) = 0

Simplifying the numerator:

(tan²(a) - 1)sin²(a) = 0

Using the identity tan^2(a) = sec²(a) - 1:

(sec²(a) - 2)sin²(a) = 0

Expanding and simplifying:

sec²(a)sin²(a) - 2sin²(a) = 0

sin²(a)(sec^2(a) - 2) = 0

So either sin²(a) = 0 or sec²(a) - 2 = 0.

If sin²(a) = 0, then a is an integer multiple of pi (i.e., a = n×π for some integer n).

If sec²(a) - 2 = 0, then sec²(a) = 2,

cos(a) = ±√(2)/2

So a can be π/4 or 7π/4.

Therefore, the solutions for a are:

a = n×π, π/4, or 7π/4, where n is any integer.

A fraction represents a part of a number or any number of equal parts. There is a fraction, containing a numerator(upper value) and denominator(lower value).

To find out how much farther the beetle crawled than the spider, we need to subtract the distance the spider crawled from the distance the beetle crawled.

The beetle crawled 2/3 of a yard, which can be written as a fraction with a common denominator of 15: 10/15.

The spider crawled 3/5 of a yard, which can also be written as a fraction with a common denominator of 15: 9/15.

How to evaluate for variable x of the adjacent angles

The triangles RDS and ADB area similar thus the lines AB and RS are parallel to each other and the adjacent angles of m∠SRA and m∠BAR are supplementary, so their sum is equal to 180°.

m∠SRA and m∠BAR are supplementary so;

(6x + 8)° + (9x + 7)° = 180°

15x + 15 = 180°

15x = 180° - 15 {subtract 15 from both sides}

15x = 165

x = 165/15 {divide through by 15}

x = 11

m∠A = 9(11) + 7 = 106°

m∠R = 6(11) + 8 = 74°

m∠S = 4(11) + 14 = 58°

Therefore, the similar triangles have adjacent angles A and R to be supplementary and value of the variable x is equal to 11. The angles m∠A = 106°, m∠R = 74°, and m∠S = 58°

to jog? Write an inequality and find the number of whole laps Claire completes.

Answers

The inequality that represent how many laps she can do is "number of laps < 8.4".

Claire can jog a maximum of 8 laps in 42 minutes.

What number of whole laps did Claire completes?

Since Claire can jog one lap in 5 minutes, we can use division to find how many laps she can complete in 42 minutes:

= 42 minutes / 5 minutes per lap

= 8.4 laps

However, since Claire cannot jog a fractional number of laps, we need to round down to the nearest whole number of laps. This is because she will have only completed a fraction of a lap by the time she reaches the end of the 42 minutes, and we want to know how many whole laps she completes. Therefore, we can write the inequality as "number of laps < 8.4".

A mobile base station (BS) in an urban environment has a power measurement of 25 µW at 325 m. If the propagation follows an inverse 4th power law (Section 3.2.2), what is a reasonable power value, in µW, to assume 1.3 km from the BS?

Give your answer in scientific notation to two decimal places.

Answers

Hence, 1.56 W (or, in scientific notation, 1.56 x 10-6 W or 1.56E-06 W) to equation two decimal places is a fair power figure to assume at a distance of 1.3 km from the BS.

What is equation?

A mathematical equation is a process that links two statements and indicates equality using the equals sign (=). A mathematical statement that proves the equality of two mathematical expressions is known as an equation in algebra. For instance, the equal sign separates the numbers 3x + 5 and 14 in the equation 3x + 5 = 14. A mathematical formula may be used to understand the link between the two sentences that are written on opposite sides of a letter. Frequently, the logo and the particular software are identical. like in 2x - 4 = 2, for example.

The received power at a distance d is determined by:

Pr is equal to Pt, Gt, Gr, and (/4d)2.

where:

The transmitted power is Pt.

The transmitter antenna gain is Gt.

the receiver antenna gain, or Gr.

is the signal's wavelength.

Pr2 = (d1/d2)4 * Pr1

where:

At a distance of 325 m, Pr1 is the received power, which is specified as 25 W.

d1 is 325 metros away, while d2 is 1.3 kilometres away (i.e., 1300 m)

Inputting the values provided yields:

Pr2 = 25 W * (325/1300 m)4 = 25 W * 0.0625 = 1.5625 W

Hence, 1.56 W (or, in scientific notation, 1.56 x 10-6 W or 1.56E-06 W) to two decimal places is a fair power figure to assume at a distance of 1.3 km from the BS.
