Answer:

I think it would be 100

Step-by-step explanation:

because 10^2 is 10 x 10 which equals 100 and so if you have 1/10^2 it's basically saying 1 divided by 10^2 and 10^2 is 100 so it would be 1 divided by 100 which equals 100.

I hope this helped any.

1/10^2 equals 1 divided by 100 or 10 to the power of -2 in exponent notation. The negative sign indicates division by the base (10) raised to the positive power (2).

The expression

1/10^2

represents a fraction where the denominator is 10 raised to the power of 2. By definition, any number (except 0) raised to the power of 2 is that number multiplied by itself. So, 10^2 equals 10*10 which is 100. Therefore,

1/10^2 = 1/100

. This can be written using exponents as

10^-2

, because 1 divided by any number is equivalent to that number raised to the power of -1, and if the number itself is an exponent, then the negative applies to the power. So, 1/10^2 (1 divided by 10 squared) is equivalent to 10 to the power of -2.

Step-by-step explanation:

we know that

The formula to solve a quadratic equation of the form

[tex]ax^{2} +bx+c=0[/tex]

is equal to

[tex]x=\frac{-b\pm\sqrt{b^{2}-4ac}} {2a}[/tex]

in this problem we have

[tex]6x^{2} +7x+k=0[/tex]  

so

[tex]a=6\\b=7\\c=k[/tex]

substitute in the formula

[tex]x=\frac{-7\pm\sqrt{7^{2}-4(6)(k)}} {2(6)}[/tex]

[tex]x=\frac{-7\pm\sqrt{49-24k}} {12}[/tex]

so

[tex]x_1=\frac{-7+\sqrt{49-24k}} {12}[/tex]

[tex]x_2=\frac{-7-\sqrt{49-24k}} {12}[/tex]

Remember that

[tex]2x_1+3x_2=-4[/tex]

substitute

[tex]2(\frac{-7+\sqrt{49-24k}} {12})+3(\frac{-7-\sqrt{49-24k}} {12})=-4[/tex]

[tex](\frac{-14+2\sqrt{49-24k}} {12})+(\frac{-21-3\sqrt{49-24k}} {12})=-4[/tex]

Multiply by 12 both sides

[tex](-14+2\sqrt{49-24k})+(-21-3\sqrt{49-24k})=-48[/tex]

[tex]-35-\sqrt{49-24k}=-48[/tex]

[tex]\sqrt{49-24k}=48-35[/tex]

[tex]\sqrt{49-24k}=13[/tex]

squared both sides

[tex]49-24k=169\\24k=49-169\\24k=-120\\k=-5[/tex]

therefore

The equation is

[tex]6x^{2} +7x-5=0[/tex]  

The roots are

[tex]x=\frac{-7\pm\sqrt{49-24(-5)}} {12}[/tex]

[tex]x=\frac{-7\pm\sqrt{169}} {12}[/tex]

[tex]x=\frac{-7\pm13} {12}[/tex]

[tex]x_1=\frac{-7+13} {12}=\frac{1} {2}[/tex]

[tex]x_2=\frac{-7-13} {12}=-\frac{5} {3}[/tex]

Final answer:

To find the constant k, use Vieta's formulas to express x_1 and x_2 in terms of the equation coefficients, then solve the given equation 2x_1+3x_2=−4 to find individual values for x_1 and x_2, and use these values to determine k through the product of the roots.

Explanation:

The student needs to find the constant k in the equation 6x^2+7x+k=0, given that x_1 and x_2 are roots of this equation, and that 2x_1+3x_2=−4. According to Vieta's formulas, which relate the roots of a polynomial to its coefficients, the sum of the roots is −(b/a) and the product of the roots is (c/a). Since the coefficient of x^2 (a) is 6 and the coefficient of x (b) is 7, we can state that x_1 + x_2= −7/6 and x_1x_2 = k/6.

Using the second given condition, 2x_1+3x_2=−4, we can substitute x_2 from the first Vieta's formula: x_2= −(7/6)−x_1, and plug this into the second condition to get 2x_1+3(−(7/6)−x_1)=−4. Simplifying, we find a value for x_1. We then substitute this x1 back into the expression for x_2 to find its value. With both x_1 and x_2 found, we use the product of the roots to find k: k = 6(x_1x_2).

Answer:

1) The slope of the function [tex]g(x)[/tex] is [tex]0[/tex] and the slope of the function [tex]f(x)[/tex] is [tex]-1[/tex].

2) The negative slope of the function [tex]f(x)[/tex] shows that it is the line is increasing and the slope [tex]0[/tex]  of the function  [tex]g(x)[/tex]  shows that the line will always have the same y-coordinate.

3) The slope of the function is [tex]f(x)[/tex] is greater than the slope of the function  [tex]g(x)[/tex].

Step-by-step explanation:

 For this exercise you need to know that the slope of any horizontal line is zero ([tex]m=0[/tex])

The slope of a line can be found with the following formula:

[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]

You can observe in the graph of the function  [tex]g(x)[/tex]  given in the exercise, that this is an horizontal line.  Then,  you can conclude that its slope is:

[tex]m=0[/tex]

The steps to find the slope of the function [tex]f(x)[/tex] shown in the table attached, are the following:

- Choose two points, from the table:

[tex](0,3)[/tex] and [tex](4,-1)[/tex]

- You can say that:

[tex]y_2=-1\\y_1=3\\\\x_2=4\\x_1=0[/tex]

- Substitute values into the formula [tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]:

[tex]m=\frac{-1-3}{4-0}[/tex]

- Finally, evaluating, you get:

[tex]m=\frac{-4}{4}\\\\m=-1[/tex]

Therefore:

1) The slope of the function [tex]g(x)[/tex] is [tex]0[/tex] and the slope of the function [tex]f(x)[/tex] is [tex]-1[/tex].

2) The negative slope of the function [tex]f(x)[/tex] shows that it is the line is increasing and the slope [tex]0[/tex]  of the function  [tex]g(x)[/tex]  shows that the line will always have the same y-coordinate.

3) The slope of the function is [tex]f(x)[/tex] is greater than the slope of the function  [tex]g(x)[/tex].

The shortest distance from the park to the library, forming a right-angled triangle with sides of 6 miles and 11 miles, can be found using the Pythagorean theorem, and it is approximately 12.5 miles when rounded to the nearest half mile.

Explanation:

The question involves finding the shortest distance from the park to the library. This is a basic problem of geometry that can be solved using the Pythagorean theorem. Since the park is 6 miles due west of your house and the library is 11 miles north, we can form a right-angled triangle with one side as 6 miles and the other side as 11 miles.

We find the shortest distance by calculating the hypotenuse of the right-angled triangle:

Represent the distances as sides of a triangle: one leg is 6 miles (west) and the other is 11 miles (north).

Apply the Pythagorean theorem: hypotenuse2 = 62 + 112

Calculate the hypotenuse: hypotenuse = √(62 + 112) = √(36 + 121) = √157

Find the nearest half mile: √157 is approximately 12.53. So rounded to the nearest half mile, the distance is 12.5 miles.

Therefore, the shortest distance from the park to the library is about 12.5 miles.

7.2cm

Step-by-step explanation:

Answer: 7.2 cm

Explanation: It's important to understand that the radius is equal to half of the diameter so to find the diameter of a circle with a radius of 3.6 cm, we simply multiply 3.6 cm by 2 and we will get the diameter or the distance across a circle.

To multiply a decimal times a whole number such as 3.6 x 2, first line up the numbers and begin multiplying as if we were multiplying 2 whole numbers.

6 x 2 is 12 so we bring down the 2 and carry the 1.

2 x 3 is 6 and if we add 1 we get 7.

So we have 7.2 cm which is our diameter

There were two  hundred seven guests. Kayla charges $27.00 per guest for food and $10.00 per guest for drinks. To  that she adds $4.98 per guest for service. What was Kayla's total bill for catering the party?

The total bill for catering the party is $ 8689.86

Kayla’s Catering provided the food, drinks, and service for the party

Total number of guests = 207

Charge for food for 1 guest = $ 27

Charge for drink for 1 guest = $ 10

Charge for service for 1 guest = $ 4.98

To find: Kayla total bill for cater

Total bill = Total number of guests(Charge for food for 1 guest + Charge for drink for 1 guest + Charge for service for 1 guest)

[tex]Total\ bill = 207(27+10+4.98)\\\\Total\ bill = 207(37 + 4.98)\\\\Total\ bill = 207 \times 41.98\\\\Total\ bill = 8689.86[/tex]

The value of x is [tex]x=\frac{-1+\sqrt{37}}{12}[/tex] and [tex]x=\frac{-1-\sqrt{37}}{12}[/tex]

Step-by-step explanation:

The equation is [tex]\frac{1}{x}-\frac{2}{3}=4 x[/tex]

Subtracting by [tex]4x[/tex] on both sides,

[tex]\frac{1}{x}-\frac{2}{3}-4 x=0[/tex]

Taking LCM,

[tex]\frac{3-12 x^{2}-2 x}{3 x}=0[/tex]

Multiplying by 3x on both sides,

Good job

Step-by-step explanation:

To buy 78 cookies using packages of 13 or 39, you can either buy 2 packages of 39 or 5 packages of 13 and 1 additional cookie.

To find the number of ways you can buy 78 cookies using packages of 13 or 39, we need to consider the different combinations of packages.

Let's start with the largest package size, 39. If you buy 2 packages of 39, that's a total of 78 cookies. So one option is to buy 2 packages of 39.

Now let's consider the smaller package size, 13. If you buy 5 packages of 13, that's a total of 65 cookies. To reach a total of 78 cookies, you can buy 5 packages of 13 and 1 additional cookie.

Therefore, the total number of ways you can buy 78 cookies is 2 (using only packages of 39) or 1 (using 5 packages of 13 and 1 additional cookie).

The surface area of the prism is equal to

[tex]SA=2B+PL[/tex]

where

B is the area of the base of the prism

P is the perimeter of the base

L is the length or the height of the prism

step 1

Find the area of the triangular base B

The area of triangular base B is

[tex]B=\frac{1}{2}(8)(6)=24\ units^2[/tex]

The perimeter of the triangular base P is

[tex]P=8+6+10=24\ units[/tex]

we have

substitute the values in the formula

[tex]SA=2(24)+24(8.5)=252\ units^2[/tex]

The equation that represents the plant's height H after M months is H = 45 + M. Substituting 33 for M gives us a plant height of 78 centimeters after 33 months.

To find the equation that relates H to M, we start with the initial height of the plant, which is 45 centimeters. We are given that the plant grows by one centimeter each month, this information provides us with a constant rate of growth.

The equation can therefore be expressed as:

H = 45 + M

Using this equation, we can calculate the height of the plant after 33 months. To do this, we simply substitute 33 for M in our equation:

H = 45 + 33

H = 78

Therefore, the plant's height after 33 months will be 78 centimeters.

Answer:

After 3 months the total cost of each health club will be the same, and the total cost for each one will be US$ 55

Step-by-step explanation:

1. Let's review the information provided to us to answer the question correctly:

Club A = Membership fee of $ 16 + Monthly fee of $13

Club B = Membership fee of $ 22 + Monthly fee of $11

2. After how many months will the total cost of each health club be the​ same? What will be the total cost for each​ club?

For answering the question, we will use the variable x to be the number of months of membership of the two clubs, this way:

Club A = Club B

16 + 13x = 22 + 11x

13x - 11x = 22 - 16

2x = 6

x = 6/2 = 3

Substituting and proving x = 3:

16 + 13x = 22 + 11x

16 + 13 * 3 = 22 + 11 * 3

16 + 39 = 22 + 33

55 = 55

After 3 months the total cost of each health club will be the same, and the total cost for each one will be US$ 55

It is Arithmetic.

Step-by-step explanation:

1) A sequence is geometric when it goes from a term to the next term by  multiplying by the same number, which is called "Common ratio" ([tex]r[/tex]).

2) A sequence is arithmetic when it goes from a term to the next term by  adding or subtracting a common value. This value is called "Common difference" and it is denoted with [tex]d[/tex].

Then, given the following sequence:

[tex]3, 1, -1, -3[/tex]

- Let's find out if it is geometric by dividing  each term by its previous one. Then:

[tex]\frac{-3}{-1}=3\\\\\frac{-1}{1}=-1[/tex]

Since there is no Common ratio, it is not a Geometic sequence.

- Now let's see if it is  arithmetic by subtracting each term by its previous one:

[tex]-3-(-1)=-2\\\\-1-1=-2\\\\1-3=-2[/tex]

A square with a whole number side length would have the same perimeter or area as the dog pen, assuming that the pen is rectangular.

If a square with a side length of s has the same perimeter as the dog pen, then we can write:

4s = 2(l + w) 2s = l + w

Since s is a whole number, l + w must be an even number. This means that both l and w must have the same parity (they must both be even or both be odd) for the equation to be true. However, if both l and w are even, then the ratio of l:w will not be a whole number, which means that a square with the same area as the dog pen cannot exist with whole number side lengths.

If a square with a side length of s has the same area as the dog pen, then we can write:

[tex]s^2[/tex]= lw

Since s is a whole number, we can express it as the product of two whole numbers:

s = ab

Substituting this into the equation for the area, we get:

[tex]a^2 b^2[/tex] = lw

This means that l and w must have at least two factors each that are perfect squares. However, if we assume that the dog pen is rectangular, then its dimensions cannot both have two factors that are perfect squares, which means that a square with the same area cannot exist with whole number side lengths.
