Step-by-step explanation:

The simplified exponential expression for this problem are given as follows:

\(5xy\sqrt[3]{7x^2y}\)

Considering the root, the expression can be written with a fractional exponent, as follows:

(875x^5y^4)^(1/3).

First we start simplifying the symbolic variables x and y, applying the power of power rule, as follows:

The number 875 can be simplified as follows:

\(\sqrt[3]{875} = \sqrt[3]{7 \times 125} = 5\sqrt[3]{7}\)

Multiplying the simplification of each term, the simplified expression is given as follows:

\(5xy\sqrt[3]{7x^2y}\)

Answer: 42.6

Step-by-step explanation:

First you would  distribute the outer number to all the inner numbers:

6*3.1 + 6*4 = 18.6 + 24

Next you would add the numbers you just got:

18.6 + 24 = 42.6

The congruent reason for the triangles is (b) HL theorem

From the question, we have the following parameters that can be used in our computation:

Triangles = FGH and JHK

The SSS similarity theorem implies that the corresponding sides of the two triangles in question are not just similar, but they are also congruent

From the question, we can see that the following corresponding sides on the triangles:

Sides GH and HK

Sides FH and JK

These parameters are given in reasons (2) and (3) and it implies that these sides are congruent sides

For the triangle to be congruent by SSS, the following sides must also be congruent

GH must be congruent to HK

The above statement is true because point H is the midpoint of line GK

This is indicated in reason (2)

Hence, the congruent statement is SSS.

However, we can also make use of the HL theorem in (B)

The correct answer is option (e): None of these answers is correct.

The statement "the mode is the most frequently occurring data value" is true. However, none of the options provided accurately describes the relationship between the mode and the mean.

The mode and the mean are different measures of central tendency and can have different values. There is no general rule or guarantee that the mode will always be larger or smaller than the mean. The relationship between the mode and the mean depends on the specific dataset and its distribution. Therefore, none of the provided options correctly describes the relationship between the mode and the mean.

The proportion of children with an MDI of at least 80 is approximately 0.0062.

Hence, option (c) is the correct answer.

The proportion of children who have an MDI of at least 80 can be found by using a standard normal table.

Now we will find the z-score for 80, and then find the corresponding cumulative probability.

With mean = 100 and

standard deviation = 8,

we have z = (80 - 100) / 8

=> z = -2.5.

Using a standard normal table,

we find that the cumulative probability for z = -2.5 is approximately 0.0062.

The standard normal distribution table is a collection of regions from the standard normal distribution, sometimes referred to as a bell curve, and it shows the size of the region under the bell curve and to the left of a particular z-score to illustrate probabilities of occurrence in a specific population.

According to the given APR, the finance charge did she save by paying her bill in full is $12.6165

APR

APR represents the yearly interest generated by a sum that's charged to borrowers or paid to investors. And it is expressed as a percentage that represents the actual yearly cost of funds over the term of a loan or income earned on an investment.

Given,

Daya paid her credit card bill in full in September. Her October bill showed a finance charge, and she wants to see whether it is correct or not. The average daily balance is $970.50, and the APR is 15.6%.

Here we need to find the finance charge did she save by paying-her bill in full.

Here the finance charge is calculated by using the formula,

=> Finance charge = Average daily balance × monthly periodic rate.

In order to find these we need the value of,

=> Monthly periodic rate = APR / 12 months

And the monthly periodic rate is calculated as,

=> Monthly periodic rate = 15.6% / 12

=> 0.156 / 12

=> 0.013

Therefore, the finance charge is calculated as,

=> Finance charge = $970.50 × 0.013

=> $12.6165

(b) minimum average cost?

Sol:

Graph of function is:

The value of such that = k * 180, where k is an integer, is the value at which cotangent is undefinable.

Cotangent, or cot, is one of the six standard trigonometric functions. Cotangent of an angle is defined as the ratio of the adjacent side to the opposite side of a right-angled triangle.

The value of cotangent is undefined when the denominator is zero. This implies that cotangent is undefined at angles where the value of sine is zero.

Since the sine function is periodic and has a period of 360 degrees, the values of sine repeat themselves after every 360 degrees.

For this reason, cotangent is undefined at angles such that θ = k * 180, where k is an integer.

That is, cotangent is undefined at 0°, 180°, 360°, and so on. It is also important to note that cotangent is a periodic function, and its values repeat every 180 degrees.

Therefore, cotangent is undefined at 0° + k * 180°, where k is an integer.

To summarize, the value of Θ at which cotangent is undefined is such that θ = k * 180, where k is an integer.

Step-by-step explanation:

Answer:

A. h(x) = 6x2 – 10x – 4

Step-by-step explanation:

Got 100% on edge.

The value of h(x) is h(x) = 6x^2 -10x + 4

The functions are given as:

f(x) = 2x - 4

g(x) = 3x + 1

So, we have:

h(x) = f(x)g(x)

This gives

h(x) = (2x - 4) * (3x+ 1)

Evaluate

h(x) = 6x^2 + 2x - 12x - 4

This gives

h(x) = 6x^2 -10x + 4

Hence, the value of h(x) is h(x) = 6x^2 -10x + 4

The mean for the number of people with the genetic mutation in such groups of 600 is 18.

Given that,

About 3% of the population has a particular genetic mutation.

This means that for any group of people, 3% of the people has a particular genetic mutation.

This is a binomial distribution.

Probability that people having genetic mutation = 3% = 0.03

Random sample size = 600

Mean for a binomial distribution can be calculated as,

Mean = n × p

         = 600 × 0.03

         = 18

It took Emily 33.4 minutes to make dinner.

A mixed number is a kind of fraction that also has a proper fraction and a whole number. The number of whole units is represented by the whole number, and the fraction of a unit is represented by the proper fraction.

To solve the problem, we have to convert the mixed number  \(9 \frac{1}{10}\)   to a decimal number:

⇒ \(9 \frac{1}{10} = 9 +\frac{1}{10} = \frac{(9*10)+1}{10}\)

⇒ \(\frac{91}{10}\)  =  9.1

This means that Emily finished making dinner 9.1 minutes sooner than the cake.

To find out how long it took Emily to make dinner, we can subtract 9.1 from the cake baking time:

⇒ 42.5 - 9.1 = 33.4 minutes
