what is the output of the following functions for x=2 f(x)=2x^4-x^3+5x-9

Answer:

we can compare 4 x 3 and 2 x 6, equal to 12. So, we can see that both products are similar and neither is greater.

Step-by-step explanation:

We can use the commutative property of multiplication to see that 3 x 4 is the same as 4 x 3 and 6 x 2 is the same as 2 x 6. When multiplying two numbers, the order of the numbers does not affect the product. Therefore, we can compare 4 x 3 and 2 x 6, equal to 12. So, we can see that both products are similar and neither is greater.

Based on the diagram, we can see that the triangle formed by the line segment with length 8 and the two dashed line segments is a right triangle with a 45° angle. This means that the other two angles of the triangle are also 45° each.

Using the properties of 45°-45°-90° triangles, we know that the length of the hypotenuse is equal to the length of either leg times the square root of 2. Therefore, we have:

x = 8 / sqrt(2) = 8 * sqrt(2) / 2 = 4 * sqrt(2)

So the value of x is option B: 8√2 / 2 or simplified, 4√2.

  (d)  101,376 square inches

Step-by-step explanation:

At $5.50 each, Larry can afford ...

  $485/($5.50/board) ≈ 88.2 boards

Each of the 88 boards is 8 inches wide and 144 inches long, so the total area Larry can afford to cover is ...

  (88)×(8 in)(144 in) = 101,376 in²

The derivative of the function is (5/2)x² - 2, the critical points are \((\frac{2\sqrt{5} }{5}, -\frac{8\sqrt{5} }{15}), (-\frac{2\sqrt{5} }{5}, \frac{8\sqrt{5} }{15})\), the points of inflection of the function is at (0,0)

(a) The derivative of f(x) is f'(x) = (5/2)x² - 2.

(b) The critical points occur where f'(x) = 0 or where f'(x) is undefined.

Setting f'(x) = 0, we get (5/2)x² - 2 = 0,

\((\frac{2\sqrt{5} }{5}, -\frac{8\sqrt{5} }{15}), (-\frac{2\sqrt{5} }{5}, \frac{8\sqrt{5} }{15}\)

(c) f'(x) = (5/2)x² - 2 is positive when x > (2√5)/5 and negative when x < (-2√5)/5. Therefore, f(x) is increasing on the interval

\((-\infty, -\frac{2\sqrt{5} }{5}), (\frac{2\sqrt{5} }{5}, \infty)\\\) and it decreases along the interval of

\((-\frac{2\sqrt{5} }{5}, \frac{2\sqrt{5} }{5})\)

(d) The second derivative of f(x) is f''(x) = 5x

(e) f''(x) is positive when x > 0 and negative when x < 0. Therefore, f(x) is concave up on the interval (0, infinity) and concave down on the interval (-infinity, 0).

(f) The points of inflection for f(x) are (0,0)

The rest wavelength of the emission line observed at 2148 nanometers in the galaxy 100 million light-years away is approximately 2103 nanometers.

The rest wavelength of an emission line can be determined by applying the concept of redshift, which is a phenomenon observed in astrophysics where light from distant objects is shifted towards longer wavelengths due to the expansion of the universe.

In this case, the emission line is observed at 2148 nanometers (or 2.148 micrometers) in a galaxy located 100 million light-years away. To calculate the rest wavelength, we need to consider the redshift factor. Redshift, denoted by z, is defined as the observed wavelength divided by the rest wavelength minus 1.

Given that the observed wavelength is 2.148 micrometers and the galaxy is located 100 million light-years away, we need to convert the distance into a redshift factor using the cosmological relationship between redshift and distance. Assuming a standard cosmological model, we can use the Hubble constant to estimate the redshift.

The Hubble constant represents the rate at which the universe is expanding. Taking a typical value of the Hubble constant as 70 kilometers per second per megaparsec, we find that the redshift factor, z, is approximately 0.021.

To determine the rest wavelength, we rearrange the redshift equation as \((observed wavelength) = (1 + z) \times (rest wavelength)\). Substituting the values, we get \((2.148 micrometers) = (1 + 0.021) \times (rest wavelength).\)

Simplifying the equation, we find the rest wavelength to be approximately 2.103 micrometers or 2103 nanometers.

Step-by-step explanation:

Answer:0.916

The decimal multiplier to decrease by 8.4% is 0.916.

Step-by-step explanation:

The comparison of the numbers stated in different measurements of ounces, pounds, and tons is as follows:

7) 16lb > 16oz

8)  1,500lb < 2T

9) 3T > 5,999lb

10)  1,600oz > 10lb

11) 19lb > 300oz

12) 8oz = ¹/₂lb.

The different measurements for weight include ounce, pound, and ton.

We know that 16 ounces equals 1 pound (lb.) and 2,000 pounds equals 1 ton.

1lb = 16oz

1 ton = 2,000lb

7) 16lb > 16oz, because 16lb = 256oz. (16 x 16)

8) 1,500lb < 2T, because 2T = 4,000lb (2,000 x 2)

9) 3T > 5,999lb, because 3T = 6,000lb (2,000 x 3)

10) 1,600oz > 10lb, because 1,600oz = 100lb (1,600 ÷ 16)

11) 19lb > 300oz, because 19lb = 304oz (19 x 16)

12) 8oz = ¹/₂lb., because 8oz = ¹/₂lb. (8 ÷ 16)

Thus, the different measurements have been compared using greater than (>), less than (<), or equal to (=).

Step-by-step explanation:

The angle measure of ∠F is approximately 66.9º.

What is an angle?

To find ∠F, we can use the Law of Cosines:

c² = a² + b² - 2ab cos(C)

Where c is the side opposite to the angle we want to find (in this case, side EF), a and b are the other two sides, and C is the angle opposite to side c (in this case, ∠F).

First, we need to find the length of side EF:

EF² = DE² + DF² - 2DE * DF cos(∠D)

EF² = (9.8)² + (5.6)² - 2(9.8)(5.6)cos(149º)

EF² ≈ 95.415

EF ≈ 9.769

Now, we can use the Law of Cosines again to find ∠F:

EF² = DE² + DF² - 2DE * DF cos(∠F)

cos(∠F) = (DE² + DF² - EF²) / 2DE * DF

cos(∠F) = ((9.8)² + (5.6)² - (9.769)²) / (2 * 9.8 * 5.6)

cos(∠F) ≈ 0.4035

∠F ≈ \(cos^{-1(0.4035)}\)

∠F ≈ 66.9º (rounded to the nearest 10th)

Therefore, the measure of ∠F is approximately 66.9º.

9+7+3 = 19 jerseys. 7 of them are large.

The probability of picking a large jersey is:

7/19.

After you already picked up one large jersey, you're left with 6 out of 18 jerseys: 6/18

So, the probability will be:

The value following are

vertex: (6, -9)

y-intercept: (0, 27)

X = 3, 9

Finding Vertex (Part A)

Consider the formula -b/2a. This formula gives you the x-coordinate of the vertex.

\(y = 1x^2 - 12x + 27\)

a = 1

b= -12

c =27

-b/2a = - (-12)/2(1) = 12/2 = 6 (x-coordinate of vertex)

When solving for the y-coordinate of the vertex you will need to substitute your 'x" back into the equation.

\(y = 1(6)^2 - 12(6) + 27\)

y = 36 - 72 + 27 = -9 (y-coordinate of vertex)

--------------------------------------------------------------------------

Y- Intercept (Part B)

When looking for the y-intercept your "x" must always be 0.

Substitute 0 in every "x" in the equation.

y =\(1(0)^2 - 12(0) + 27\)

y = 27

y-intercept: (0, 27)

-----------------------------------------------------------------------------

X- Intercepts (Part C)

To find the values of the "x" factor.

\(y = 1x^2\) - 12x + 27

\(0 = 1x^2\) - 12x + 27

0 = (x  - 3     )(x   -  9 )

(x-3) = 0             (x-9) = 0

x = 3                    x = 9

The probability of drawing a king from a standard deck of 52 cards is 1/13.

In a standard deck of 52 playing cards, there are four kings: the king of hearts, the king of diamonds, the king of clubs, and the king of spades.

To find the probability of drawing a king, we need to determine the ratio of favorable outcomes (drawing a king) to the total number of possible outcomes (drawing any card from the deck).

The total number of possible outcomes is 52 because there are 52 cards in the deck.

The favorable outcomes, in this case, are the four kings.

Therefore, the probability of drawing a king is given by:

Probability = (Number of favorable outcomes) / (Number of possible outcomes)

= 4 / 52

= 1 / 13

Thus, the probability of drawing a king from a standard deck of 52 cards is 1/13.

This means that out of every 13 cards drawn, on average, one of them will be a king.

It is important to note that the probability of drawing a king remains the same regardless of any previous cards that have been drawn or any other factors.

Each draw is independent, and the probability of drawing a king is constant.

While an absolute value may be any number, the output from an absolute value expression is always greater than or equal to zero

The absolute value | x | of a real number x is defined as the non-negative value of x without regard to its sign. For example, the absolute value of 3 is 3, and the absolute value of −3 is also 3. The absolute value of a number may be thought of as its distance from zero along real number line.

The absolute value of any number is seen to be always greater than or equal to zero. Both a number and its opposite are the same distance from zero on the number line. Since they have the same distance from zero, they have the same absolute value.
