y = 34 · (1 / 2)

y = 17

Case 5

x = y = 10

Case 6

x = 25√3 / (√3 / 2)

x = 50

y = 25√3 / √3

y = 25

Case 7

x = y = 2√14 · √2 = 2√28 = 4√7

Case 8

x = 24 / (√3 / 2)

x = 48 / √3

x = 16√3

y = 24 / √3

y = 8√3

Case 9

x = 22√3 · (1 / 2)

x = 11√3

y = 22√3 · (√3 / 2)

y = 33

Case 10

x = √18

x = 3√2

y = √6 / (1 / 2)

y = 2√6

Case 11

x = √10

y = √20

y = 2√5

Case 12

x = 4√21 / √3

x = 4√7

y = 4√21 / (1 / 2)

y = 8√21

The remainder of given equation is 1.we can find by using polynomial remainder to find the remainder of given equation.

The remainder theorem is that if a polynomial p(x) is divided by (x−a), then the remainder is a constant given by p(a). we divide a polynomial P(x) by a factor ( x – a).It is not essentially an element will of the polynomial.

when a polynomial is p ( a ) is divided by another binomial ( a – x ), then the remainder of the end result that is obtained is p ( x ).Finding the remainder is an easy method. We need to just divide the number by another number with its multiples and get the remainder.

Now we have equation

p(x)= \(x^{2}\)+x+1

x+1=0    x=-1

p(-1)= (\(-1^{2}\)) +(-1) +1

p(-1) = 1-1+1

p(-1) = 1

The values of b and a for the logarithmic function in this problem are given as follows:

The logarithmic function in the context of this problem has the format given as follows:

\(y = b\log_3{x + a}\)

The vertical asymptote is at x = -4, hence:

\(y = b\log_3{x - 4}\)

When x = 5, y = -1, hence the parameter b is obtained as follows:

\(-1 = b\log_3{5 - 4}\)

For a box given a sudden push up a ramp and the friction between the box and the ramp is not negligible, the diagrams which best represent the directions of the actual forces acting on the box as it moves upward after the push is Option A.

Friction refers to the force of resistance in the relative motion of solid surfaces in contact and sliding or rolling against each other. Frictional forces are affected by the surface texture and the amount of force impelling them together and the angle and position of the object. The actual forces acting on the box will be the normal force (always perpendicular to the surface), weight force (acting downward) and frictional force (acting opposite to the direction of push).

The value of a and b in the right triangle are 4√3 and 6 units.

A right angle triangle is a triangle that has one of its angles as 90 degrees. The sum of angles in a triangle is 180 degrees.

The sides a and b can be found using trigonometric ratios. Therefore,

sin 30 = opposite / hypotenuse

sin 30 = 2√3 / a

cross multiply

1 / 2  =  2√3 / a

a = 2√3 × 2

a = 4√3

Therefore, let's find b as follows:

cos 30 = adjacent / hypotenuse

cos  30 = b /  4√3

cross multiply

√3 / 2 = b /  4√3

4√3 × √3 = 2b

b = 12 / 2

Sorry if im wrong i guessed 45 :/

Answer:

40) 105 miles (mi)

42) 3.2 centimeters (cm)

Step-by-step explanation:

First determine which part of the ratio corresponds to what. Once you have figured that out, divide by the part of the ratio that corresponds to your given part and then multiply that by the other part of the ratio to derive the quantity.

If a:b

Then a × a/b = b, and b × a/b = a.

You can think of : as "to".

For example, you are given a map with a scale ratio of 1 in : 20 mi, this means that for every inch of the map, there is an actual distance of 20 miles.

So in this situation, the left part of the ratio is the length of the map in inches, and the right part of the ratio is the real distance in miles. For x inches of the map, there is 20 x miles of actual distance. Therefore 3.5 inches has an actual distance of 3.5 × 20 miles or 105 miles of actual distance.

For problem 2, you are given a ratio of 1 m : 2 cm, this means that for every 1 meter of the drawing, there is 2 cm of the plant. Therefore if you have 1.6 meter of the map, then you have 1.6 × 2 cm of the plant or 3.2 cm. For both situations the left part of the ratio is 1 which means that you just multiply by the right part of the ratio by which you are given.

(a) Condition 2: Constant variance: The variance of the series is constant for all t, i.e., Var(Yt) = σ², where σ² is a constant for all t. Condition 3: Autocovariance is independent of time: Cov(Yt, Yt-h) = Cov(Yt+k, Yt+h+k) for all values of h and k for all t. (b) The test statistics for the Dickey-Fuller test is DFE = p - ρ / SE(p).

(a) If we let t=1, we have Y1= E1+A E0

Now let t=2, then Y2=Y1+ E2+A E1

On applying recursive substitution up to time t, we get Yt= E(Yt-1)+A Σ i=0 t-1 Ei

From the above equation, we observe that if A≠-1, the process {Yt} will be non-stationary since its mean is non-constant. There are three conditions that ensure a covariance stationary process: Condition 1: Constant mean: The expected value of the series is constant, i.e., E(Yt) = µ, where µ is a constant for all t. If the expected value is a function of t, the series is non-stationary.

(b) The problem of applying the Dickey-Fuller test when testing for a unit root when the model of a time series is given by t = pxt-1+u, where the error term ut exhibits autocorrelation is that if the error terms are autocorrelated, the null distribution of the test statistics will be non-standard, so using the standard critical values from the Dickey-Fuller table can lead to invalid inference.

The null hypothesis for the Dickey-Fuller test is that the time series has a unit root, i.e., it is non-stationary, and the alternative hypothesis is that the time series is stationary. In DFE = p- ρ / SE(p), p is the estimated coefficient, ρ is the hypothesized value of the coefficient under the null hypothesis (usually 0), and SE(p) is the standard error of the estimated coefficient.

Answer:   w = 7,  x = 6

Step-by-step explanation:  Solve by substitution

W + b = 13

rewrite as   b = 13 - w  and substitute that value for b in the second equation

6.5w + 2b = 57.5  Then solve for w

6.5w + 2(13-w) = 57.5 . Distribute

6.5w + 26 - 2w = 57.5 .  Subtract 26 from both sides. Combine like terms and simplify

6.5w - 2w = 57.5 - 26

4.5w = 31.5  Divide both sides by 4.65

w = 7 . Substitute 7 for w in the first equation and solve for b

7 + b = 13 . Subtract 7 from both sides

b = 6

Step-by-step explanation:

Simple probability is the calculation of an outcome or the chance of an event ever happening.

18.65% probability that the person is from Washington

Two events, A and B.

\(P(B/A)=\frac{P(B)*P(A/B)}{P(A)}\)

In which P(B|A) is the probability of B happening when A has happened and P(A|B) is the probability of A happening when B has happened.

In this question:

Event A: Arrived by train.

Event B: From Washington.

15% are from Washington

This means that \(P(B)=0.15\)

12% of the attendees from Washington came to the conference by train.

This means that \(P(A/B)=0.12\)

Probability of arriving by train:

6% of 60%(from California), 17% of 25%(from Oregon) or 12% of 15%(from Washington). So

\(P(A)=0.06*0.6+0.17*0.25+0.12*0.15=0.0965\)

If an attendee is selected at random and found to have arrived by train,

\(P(B/A)=\frac{0.15+0.12}{0.0965} =0.1865\)

=0.1865

18.65% probability that the person is from Washington

A percentage is a number or ratio that represents a fraction of 100. 

The percentage decrease in the cost of the pair of pants is 20%.

A percentage is a number or ratio that represents a fraction of 100. 

Example:

50% = 50/100 = 1/2

10% = 10/100 = 1/10

25% = 25/100 = 1/4

20% = 20/100 = 1/5

We have,

The initial cost of pair of pants = $50

The final cost of pair of pants after reduced = $40

The percentage decrease in the cost of pair of pants:

= [( Initial cost - Final cost ) / Initial cost] x 100

= [(50 - 40) / 50] x 100

= (10/50) x 100

= 20%

Thus,

The given equation, 16x² - y² + 16z² = 4, represents a quadric surface known as an elliptic paraboloid.

To determine the classification, we can examine the coefficients of the squared terms. In this case, the coefficients of x², y², and z² are positive, indicating that the surface is bowl-shaped. Additionally, the signs of the coefficients are the same for x² and z², indicating that the bowl opens upward along the x and z directions.

The negative coefficient of y², on the other hand, means that the surface opens downward along the y direction. This creates a cross-section in the shape of an elliptical parabola.
