Answer:

1: 57,310

2: 89,600

3: 37,000

Step-by-step explanation:

Answer:

If $x=3$, then $y=2*3^{3}$. Using order of operations, we evaluate the exponent first, then perform the multiplication:

\begin{align*}

y &= 2 * 3^{3} \\

&= 2 * 27 \\

&= 54

\end{align*}

Therefore, $y=54$.

Answer:

1539.38

Step-by-step explanation:

this can be figured out as an entire cylinder and then take 1/2 of that

area of a circle of 7 cm

area = \(\pi\)\(7^{2}\)

area = 153.938

volume = 153.938 * 20

volume = 3078.7608

and take 1/2 of that to find volume of the half cylinder

3078.7608 / 2 = 1539.38

Step-by-step explanation:

\(8x + y = -2\)

\(4x - y = -14\)

To solve this via the addition method, we just need the two equations together; that means that we will create a new equation where the terms on the left side of both equations are added together and are set equal to the sum of the terms on the right side of both equations:

\((8x + y) + (4x - y) = (-2) + (-14)\)

\(8x + y + 4x - y = -2 - 14\)

\((8x + 4x) + (y - y) = -16\)

\(12x + 0 = -16\)

\(x = \frac{-16}{12}\)

\(x = \frac{-4}{3}\)

Now that we have solved for one term, we can plug this value into either equation to get the value for the other:

\(4x - y = -14\)

\(4(\frac{-4}{3}) - y = -14\)

\(\frac{-16}{3} - y = -14\)

\(\frac{-16}{3} + 14 = y\)

\(\frac{26}{3} = y\)

This means the solution to the system of equations is \((-\frac{4}{3}, \frac{26}{3})\)

Answer:

Step-by-step explanation:

8x + y = -2

4x - y = 14

12x = 12

x = 1

8 + y = -2

y = -10

Answer:8%

Step-by-step explanation:Since the cards are put back after each pick, the two picks are independent events.

The probability of picking a 4 on the first pick is 1/5, as there is one card with a value of 4 out of five cards in total.

The probability of picking a number greater than 4 on the second pick is 2/5, as there are two cards with values greater than 4 (5 and 6) out of five cards in total.

The probability of both events occurring (picking a 4 and then a number greater than 4) is the product of the probabilities of each event:

1/5 x 2/5 = 2/25

So the probability of picking a 4 and then picking a number greater than 4 is 2/25.

To express this as a percentage, we can multiply by 100:

2/25 x 100 = 8%

Therefore, the probability of picking a 4 and then picking a number greater than 4 is 8%.

Answer:

the first option

Step-by-step explanation:

(f-g)(x) simply means to subtract both expressions. really literally.

and we go through it power by power of x.

the highest power/exponent of x is 3 (x³). only f(x) has one.

so, -7x³ is the first part of f-g.

next is x².

11x² - 6x² = 5x², which is the second part of f-g.

next is x.

-8x - (-14x) = -8x + 14x = 6x, which is the third part of f-g.

next is x⁰ (in other words, no x, just a constant).

4 - (-3) = 4 + 3 = 7, which is the 4th part of f-g.

we have no x to the power of -1 or -2, so we have -3

0 - (-4x‐³) = 4x‐³, which is the last part of f-g.

so, it is clearly the first answer option.

The value of t(-u + 2v) is 5/6.

To find the value of t(-u + 2v), we can use the linearity property of linear transformations.

We know that t(u) = 1/2 and t(v) = 2/3.

Let's break down the expression t(-u + 2v):

t(-u + 2v) = t(-1u + 2v)

Since t is a linear transformation, we can distribute the transformation across the addition and scalar multiplication:

t(-u + 2v) = t(-1u) + t(2v)

Using the linearity property, we can factor out the scalars:

t(-u + 2v) = -1t(u) + 2t(v)

Now substitute the given values of t(u) and t(v):

t(-u + 2v) = -1×(1/2) + 2×(2/3)

Simplifying the expression:

t(-u + 2v) = -1/2 + 4/3

To add these fractions, we need a common denominator:

t(-u + 2v) = -3/6 + 8/6

Combining the fractions:

t(-u + 2v) = 5/6

Therefore, t(-u + 2v) equals 5/6.

Answer:

  (0.5, -2.5)

Step-by-step explanation:

Each of the coordinates of B(1, -5) is multiplied by the scale factor, 0.5:

  B' = (0.5·1, 0.5·(-5)) = (0.5, -2.5)

The coordinates of B' are (0.5, -2.5).

The exact value of the expression tan(π/6) sin(5π/3)⋅cos(-3π/4) is -√3/2.

We have tan(π/6). The angle π/6 is equivalent to 30 degrees. The tangent of 30 degrees is √3/3.

We have sin(5π/3). The angle 5π/3 is equivalent to 300 degrees. In the unit circle, the sine value at 300 degrees is -√3/2.

Finally, we have cos(-3π/4). The angle -3π/4 is equivalent to -135 degrees. In the unit circle, the cosine value at -135 degrees is -√2/2.

Multiplying these values together, we have (√3/3) * (-√3/2) * (-√2/2). Simplifying, we get (√3 * √3 * √2) / (3 * 2 * 2) = (√3 * √2) / 12.

Taking the negative sign into account, the final value is -√3/2, which is approximately -0.866.

The formula for calculating the effective annual rate of interest with quarterly compounding is:

(1 + r/4)^4 - 1 = A/P

where r is the quarterly interest rate, A is the final amount, and P is the principal.

In this case, P = $2,000, A = $3,000, and the time period is 7 years or 28 quarters.

So we have:

(1 + r/4)^4 - 1 = 3000/2000

(1 + r/4)^4 = 1.5

1 + r/4 = (1.5)^(1/4)

r/4 = (1.5)^(1/4) - 1

r = 4[(1.5)^(1/4) - 1]

To get the effective annual rate, we need to convert the quarterly rate to an annual rate by multiplying by 4:

effective annual rate = 4[(1.5)^(1/4) - 1] ≈ 8.84%

Therefore, the effective annual rate of interest at which $2,000 will grow to $3,000 in seven years if compounded quarterly is approximately 8.84%, rounded to 2 decimal places.

Following the volumes a cone formula, one can determine a cone's volume given the necessary inputs. When the basis radius or even the see that, height, and slanted height of the cone are determined, the further stages can be carried out.

V=1/3hπr²

Cone volume is calculated using the method V=1/3hr2. Learn how to solve a sample problem using this formula.

Step 1: Write down the given parameters, "r" denoting the radius of the cone's base, "d" denoting its diameter, "L" denoting its slant height, and "h" denoting its height.

Step 2: Apply the calculation to determine the cone's volume.

Cone volume using the base radius: V = 1/(r2h) or 1/(r2) (L2 - r2)

Cone volume using the formula V = (1/12)d2h = (1/12)d2 (L2 - r2)

Determine the volume of the a cone with a 3 inch radius and a 7 inch height. (Use π = 22/7).

Solution: We are aware of the volume

As we already know, the cone's volume is (1/3)r2h.

Taking into account that r = 3 inches, h = 7 inches, and = 22/7

So, the volume of the cone is V = (1/3)r2h V = (1/3) × (22/7) × (3)2 × (7) = 22 × 3 = 66 in3

A transformation of Total_load_present_g and/or Prescribed_total_g can help to improve the regression fit. One way to determine this is by analyzing the Residuals vs Fitted plot.

If the plot shows a funnel shape, this suggests that there is heteroscedasticity, which means that the variability of the residuals changes across the range of the predictor variable.

A log transformation of Total load present g or Prescribed total g can help to stabilize the variance of the residuals and improve the regression fit.

Similarly, if the plot shows a curved pattern, this suggests that there may be nonlinearity in the relationship between the predictor and response variables.

A polynomial or power transformation of Total_load_present_g or Prescribed_total_g can help to capture this nonlinearity and improve the regression fit.

In conclusion, a transformation of Total_load_present_g and/or Prescribed_total_g can help to improve the regression fit, depending on the shape of the Residuals vs Fitted plot. If there is heteroscedasticity or nonlinearity in the relationship between the variables, a suitable transformation can help to address these issues and improve the fit of the regression model.

A multiplier of 1.2 means the value is multiplied or increased by a factor of 1.2.

A multiplier is a term used to represent a factor by which a value is multiplied or increased. It is a numeric value that indicates the extent of the increase or expansion of a given quantity. Multiplication by a multiplier results in scaling or changing the magnitude of the original value.

A multiplier of 1.2 indicates that a value will be increased by 20% or multiplied by a factor of 1.2. This means that when the multiplier is applied to the original value, the resulting value will be 1.2 times the original.

When y = 100, x is approximately equal to 0.04.

If y varies inversely as x^2 and y = 16 when x = 5, we can find the values of x and y when y = 100.

To solve this problem, we can use the inverse variation formula, which states that y = k/x^2, where k is the constant of variation.

Given that y = 16 when x = 5, we can substitute these values into the formula to find the value of k.

16 = k/(5^2)
16 = k/25

To find k, we can cross multiply:
16 * 25 = k
400 = k

Now that we know the value of k, we can use it to find the value of y when x = 100.

y = k/(100^2)
y = 400/(100^2)
y = 400/10000
y = 0.04

Therefore, when y = 100, x is approximately equal to 0.04.
