The temperature in Juno, Alaska was 5 degrees at 7am. The temperature dropped 15 degrees every hour for 3 hours. What was the temperature at 10am?

Answer:

8 = m, No solution

Step-by-step explanation:

1. -88 = -3(4m + 5) - (1 - 3m)

-88 = -12m - 15 - 1 + 3m : distributed into parentheses

-88 = -9m - 16 : combined like terms

+16           + 16 : adding to cancel out

-72 = -9m

/-9       /-9 : dividing by -9 to cancel

8 = m

2. -4(5k - 7) + 2k = -2(9k + 5)

-20k + 28 + 2k = -18k - 10 : distributed into parentheses

-18k + 28 = -18k - 10 : combined like terms

       + 10            + 10 : adding to cancel out

-18k + 38 = -18k

+18k            +18k : adding to cancel out

38 = 0k (No solution)

an = 8⁽ⁿ⁻¹⁾⁹ + 10((n-1)(n-2)/2) is the explicit formula for the sequence {an} in terms of n.

To find an explicit formula for the sequence {an} that satisfies the given recurrence relation, we can first examine the pattern and derive a general formula.

Let's expand the recurrence relation for a few terms to observe the pattern:

a2 = 8a1 + 10(1)

a3 = 8a2 + 10(2) = 8(8a1 + 10(1)) + 10(2)

a4 = 8a3 + 10(3) = 8(8(8a1 + 10(1)) + 10(2)) + 10(3)

Expanding further, we can see that each term in the expansion contains a factor of 8 raised to a power:

a4 = 8³a1 + 8²(10) + 8¹(10) + 10(3)

Generalizing this pattern, we can write the formula for the nth term as follows:

an = \(8^(n-1)a1 + 8^(n-2)(10) + 8^(n-3)(10) + ... + 8^2(10) + 8^1(10) + 10(n-1)\)

Substituting the initial condition a1 = 9 into the formula, we have:

an =\(8^(n-1)(9) + 8^(n-2)(10) + 8^(n-3)(10) + ... + 8^2(10) + 8^1(10) + 10(n-1)\)Therefore, the explicit formula for the sequence {an} that satisfies the given recurrence relation is in term :

an = \(8^(n-1)(9) + 10(1 + 2 + 3 + ... + (n-1))\)

The sum of integers from 1 to (n-1) can be expressed as (n-1)(n-2)/2, so we can simplify the formula further:

Therefore, an = 8⁽ⁿ⁻¹⁾⁹ + 10((n-1)(n-2)/2) is the explicit formula for the sequence {an} in terms of n.

Answer:

A) Yes, m=-3 and b = -3

Step-by-step explanation:

The m is the slope of the line and the b is the y-intercept. We can see that the y-intercept is at -3, so that means D and B are not the answer. This leaves us with A and C. The slope of the line is going down instead of up, meaning that the slope of the line is negative. This means that C is not the answer.

Therefore, the answer is A, m= -3 and b= -3.

The answer is that the form of fiber art that involves placing two sets of parallel fibers at right angles and interlacing one set with the other is called weaving.

Weaving is the process of creating fabric by interlacing two sets of threads, known as the warp and weft, at right angles. The warp threads are stretched vertically on a loom, while the weft threads are woven horizontally across the warp. This results in a stable and durable fabric that can be used for a variety of purposes. Weaving has been used for centuries in cultures around the world to create clothing, textiles, and other functional and decorative items.

In weaving, the two sets of fibers are called the warp and the weft. The warp fibers run vertically and are held in tension on a loom. The weft fibers run horizontally and are woven over and under the warp fibers. This process of interlacing the warp and weft fibers creates a strong and flexible fabric, and it allows for the creation of various patterns and designs. Weaving is used in many different cultures and can be seen in a variety of fiber art forms, such as tapestries, rugs, and clothing.

The statsmodels ols() method is used on an exam scores dataset to fit a multiple regression model using exam4 as the response variable. exam1, exam2, and exam3 are used as predictor variables. the general form of this model is

The general form of a multiple regression model using exam1, exam2, and exam3 as predictor variables and exam4 as the response variable is:

exam4 = beta_0 + beta_1 * exam1 + beta_2 * exam2 + beta_3 * exam3

where beta_0 is the intercept term and beta_1, beta_2, and beta_3 are the coefficients for exam1, exam2, and exam3, respectively. These coefficients represent the change in the response variable (exam4) for a one-unit change in the predictor variables, holding all other predictor variables constant.

The statsmodels ols() method can be used to fit this multiple regression model to a dataset. The ols() method stands for "ordinary least squares," which is a method for estimating the parameters (i.e., the beta coefficients) in a linear regression model. To use the ols() method, you will need to specify the predictor variables and the response variable as input variables and provide the data for these variables as a Pandas DataFrame. You can then call the fit() method on the ols() object to fit the model to the data.

For example, if your data is stored in a Pandas DataFrame called "df," you could fit a multiple regression model using exam1, exam2, and exam3 as predictor variables and exam4 as the response variable with the following code:

import statsmodels.formula.api as smf

model = smf.ols(formula='exam4 ~ exam1 + exam2 + exam3', data=df)

results = model.fit()

Once the model is fit, you can access various summary statistics and parameters of the model using the results object. For example, you can access the coefficients of the model using the params attribute, like this:

beta_0 = results.params[0]

beta_1 = results.params[1]

beta_2 = results.params[2]

beta_3 = results.params[3]

You can also use the summary() method on the results object to get a summary of the model fit, including the R-squared value, the F-statistic, and the p-values for the coefficients.

The correct answer is D: Max (Peak Memory BW x Arithmetic Intensity, Peak Floating-Point Performance).

1a. C: 101 to calculate the speedup, we need to consider the computing load distribution among the processors. In this case, 10 processors carry 20% of the load, which means each of these processors handles 2% of the load. The remaining 90 processors share the rest of the load evenly, so each processor among these 90 handles (100% - 20%) / 90 = 0.8889% of the load.

The speedup can be calculated using Amdahl's Law, which states that the speedup is limited by the portion of the program that cannot be parallelized. In this case, the matrix subtraction is fully parallelizable, so the only portion that cannot be parallelized is the sum of the scalar variables.

The speedup formula is given by: Speedup = 1 / [(1 - p) + (p / n)], where p is the portion that can be parallelized and n is the number of processors.

In this case, p = 0.02 (for the 10 processors) and n = 100. Substituting these values into the formula, we get: Speedup = 1 / [(1 - 0.02) + (0.02 / 100)] = 1 / 0.99 = 1.0101.

Therefore, the correct answer is C: 101.

The lowest term of rational expression is 4z⁶/3

What is rational expression?

A rational expression is simply a quotient of two polynomials. Or in other words, it is a fraction whose numerator and denominator are polynomials.

Rational expressions look like fractions that have variables in their denominators (and often numerators too). For example, x 2 x + 3 \dfrac{x^2}{x+3} x+3x2 ​start fraction, x, squared, divided by, x, plus, 3, end fraction is a rational expression.

To write a rational expression in lowest terms, we must first find all common factors (constants, variables, or polynomials) or the numerator and the denominator. Thus, we must factor the numerator and the denominator. Once the numerator and the denominator have been factored, cross out any common factors.

A) The expression is undefined when x=10 or x=-5 because the denominator would be equal to zero, which is undefined in mathematics.

B) The rational expression 8z³/20z⁶ can be simplified to 2z³/5z⁶. The expression can be further simplified by dividing both the numerator and denominator by z³, giving us 2/5z³.

C) The expression 12-4/5y-36 is undefined when y=-9 or y=4 because the denominator would be equal to zero, which is undefined in mathematics.
