8+32=40

21÷3=7

21-14=7

21÷7=3

Step-by-step explanation:

The missing values are 5, 32, 3, 14, and 3 after using the arithmetic operation.

It is defined as the operation in which we do the addition of numbers, subtraction, multiplication, and division. It has a basic four operators that is +, -, ×, and ÷.

It is given that:

8⋅______=40

8+______=40

21÷______=7

21−______=7

21⋅______=7

We can use the arithmetic operation to find the unknown values:

A number is a mathematical entity that can be used to count, measure, or name things. For example, 1, 2, 56 etc. are the numbers.

8x5  = 40

8 + 32 = 40

21 ÷ 3 = 7

21 - 14 = 7

21 ÷ 3 = 7

Thus, the missing values are 5, 32, 3, 14, and 3 after using the arithmetic operation.

Answer: (x+-0.5)²=0

Step-by-step explanation:

4x²-4x+1=0

(2x-1)²=0 ⇔ completing the square

--------------------------------------------

since the question asked for the x should be 1, then we should divide 2x by 2 so to get rid of the 2 in front of the x.

this will change the original equation into: (x+(-0.5))²=0

------------------------------------------------------------------------------------------------------------

You can also directly divide 4 from 4x²-4x+1=0 to get rid off the terms in front of x.

x²-x+0.25=0

(x-0.5)²=0

(x+(-0.5))²=0

Answer:

k(t) =  (sin3, cos3, 2) + [(t - 1)(cos3, -3sin3, 7)]

Step-by-step explanation:

For a path r(t), the general equation k(t) of its tangent line at a specified point r(t₀) is given by;

k(t) = r(t₀) + r'(t₀) [t - t₀]            -----------------(i)

Where

r'(t) is the first derivative of the path r(t) at a given value of t.

From the question:

r(t) =  (sin3t, cos3t, 2[tex]t^{7/2}[/tex]) and t₀ = 1

=> r(1) = (sin3, cos3, 2) at t₀ = 1

Find the first derivative component-wise of r(t) to get r'(t)

∴ r'(t) = (cos3t, -3sin3t, 7[tex]t^{5/2}[/tex])

=>r'(1) = (cos3, -3sin3, 7)

Now, at t₀ = 1, equation (i) becomes;

k(t) = r(1) + [ r'(1) (t-1)]    [substitute the necessary values]

k(t) =  (sin3, cos3, 2) + [(t - 1)(cos3, -3sin3, 7)]

Answer:

5.75 L

Step-by-step explanation:

2(1500mL + 375mL + 1L)

=2(1875mL + 1L)

=2(1.875L + 1L)

=2(2.875)

=5.75

The recipe will yield 5.75 liters (L) of punch when doubled.

To find the total volume of punch that the recipe will yield if doubled, we need to add the amounts of each ingredient and then multiply by 2.

Original recipe:

Fruit punch: 1,500 mL

Pineapple juice: 375 mL

Ginger ale: 1,000 mL (since 1 L = 1,000 mL)

Total volume of punch in the original recipe:

= 1,500 mL + 375 mL + 1,000 mL

= 2,875 mL

Now, if we double the recipe, we need to multiply the total volume by 2:

Total volume of punch when doubled = 2×2,875 mL

= 5,750 mL

To convert this to liters (L), we divide by 1,000 since 1 liter is equal to 1,000 mL:

Total volume of punch when doubled = 5,750 mL / 1,000

= 5.75 L

Hence, the recipe will yield 5.75 liters (L) of punch when doubled.

Answer:

12x

Step-by-step explanation:

This is b/2^2, so basically you take the square root of 36 and multiply that value by 2.

so [tex]\sqrt{36}[/tex] = 6(2)=12

Hope this makes sense!

Step-by-step explanation:

First, let's look at some examples of what a perfect square trinomial looks like.  [tex]x^2 + 16x + 64[/tex]

This trinomial is made from:

[tex](x+8)^2[/tex]

So for your second question (x^2 + ___x + 36), we need to work backwards, starting with the last number of the trinomial, 36. Think of two identical numbers that would make 36 if they got multiplied together. Or: √36. Either way, we get 6. So we can put this as a squared binomial.

[tex](x+6)^2[/tex]

Then, we could solve the binomial to get our middle number. (Use FOIL: Multiply the First terms, then Outer terms, then Inner terms, and Last terms)

[tex](x+6)(x+6)[/tex]

[tex]x^2+6x+6x+36\\x^2+12x+36[/tex]

As you can see, our middle number is 12x, and that is what goes into the blank.

Answer: 12x

Let's say you had a cake that is cut into 5 equal slices. Then someone eats 2 of those slices. They ate 2/5 of the cake.

Now let's say you have another cake that you cut into 10 equal slices. If someone eats 4 of those ten, then they have eaten 4/10 = 2/5 of the cake.

Check out the diagram below to see a visual of how 4/10 and 2/5 are equivalent fractions.

Going from 2/5 to 4/10 has us multiply top and bottom by 2.

-----------

Similarly, 1/2 = 5/10 after multiplying top and bottom by 10

The original expression 2/5 + 1/2 turns into 4/10 + 5/10

Then you add the numerators to get 4+5 = 9, placing that over the common denominator of 10

Answer:

(6, 0) is located on the x-axis

Explanation:

For a point to be on the x-axis, its y-value must equal 0. (6, 0) has an x-value of 6 and a y-value of 0.

"(0, 5) is located at the origin" is not true because the origin is at (0, 0).

"(0, 5) is located on the x-axis" is not true because its y-value is 5, not 0.

"(6, 0) is located at the origin" is not true because the origin is at (0, 0).

The (6, 0) is located on the x-axis option (C) is correct because the y-coordinate is zero on the x-axis.

It is defined as a representation of coordinates in a two-dimensional coordinate plane. It has a list of two elements in it, such as (x, y).

[tex]\rm Area = |\dfrac{(x_1y_2-y_1x_2)+(x_2y_3-y_2x_3)....+(x_ny_1-y_nx_1)}{2}|[/tex]

It is given that:

The points are (6, 0) and (0, 5).

After plotting on the coordinate plane,

For a point to be on the x-axis, its y-value must equal 0. (6, 0) has an x-value of 6 and a y-value of 0.

"(6, 0) is located at the origin" is not true because the origin is at (0, 0).

Thus, the (6, 0) is located on the x-axis option (C) is correct because the y-coordinate is zero on the x-axis.

Answer:

Explained below.

Step-by-step explanation:

At the start of every month the price of gas started out at 100¢/gallon.

Then every day since, it has gone up 2¢/gallon.

The variables are denoted as follows:

d = the date

g = price of a gallon of gas

c = total price required to fill up my car, in cents.

(a)

The function that gives the price of gas on any given day of the month is:

g (d) = 100 + 2(d - 1)

The (d - 1) represent the number of times the price has gone up by 2¢/gallon.

(b)

The function that tells how much money it takes to fill up my car, as a function of the price of a gallon of gas is:

c (g) = 10 × g

Since the car takes 10 gallons of gas.

(c)

The composite function that gives the cost of filling up my car on any given day of the month is:

c (g (d)) = 10 × g (d)

            = 10 [100 + 2(d - 1)]

c (g (d)) = 1000 + 20 (d - 1)

(d)

On the 11th day the price of gas has increased by 2¢/gallon for the past 10 days.

Compute the total price it takes to fill up my car on the 11th of the month as follows:

c (g (d)) = 1000 + 20 (d - 1)

c (g (11)) = 1000 + 20 (11 - 1)

             = 1000 + (20 × 20)

             = 1000 + 400

             = 1400¢

Thus, the it takes to fill up my car on the 11th of the month is 1400¢.

(e)

The total price to fill the car on the nth day is 1040¢.

Compute the value of n as follows:

      c (g (d)) = 1000 + 20 (d - 1)

          1040 = 1000 + 20 (n - 1)

1040 - 1000 = 20 (n - 1)

              40 = 20 (n - 1)

          (n - 1) = 2

                 n = 3

Thus, the day on which it cost 1,040¢ to fill up the car is the 3rd day.

Answer:

  f(777) = 390

Step-by-step explanation:

f(1) = 2 . . . . given

f(2) = f(f(1)) = 3 . . . . given

f(3) = f(f(f(1))) = 1+4 = 5

f(5) = f(f(3)) = f(f(f(2))) = 2+2 = 4

f(4) = f(f(5)) = f(f(f(3))) = 3+4 = 7

f(7) = f(f(4)) = f(f(f(5))) = 5+4 = 9

Then the sequence of sequential function values is ...

  2, 3, 5, 4, 7, 9, 6, 11, 13, ... (pattern repeats in groups of 3)

__

Each odd number of the form 4n+1 is the function value f(4n-1) = 4n+1.

Similarly, the next function value is f(4n+1) = (4n+1+3)/2.

Since 777 is 4(194) +1, we have ...

  f(777) = (777+3)/2

  f(777) = 390

Answer:

The value is [tex]P (I | L ) = 0.63[/tex]

The probability has increased

Step-by-step explanation:

From the question we are told that

   The percentage that are from outside the country is  [tex]P(O) = 0.70[/tex]

    The  percentage that logs on everyday is  [tex]P(L) = 0.60[/tex]

    The  percentage that logs on everyday that are from the inside the country is     [tex]P(L | I) = 0.80[/tex]

Generally using Bayes' Rule the probability that a person is from the country given that he logs on the website every day is mathematically represented as

     [tex]P (I | L ) = \frac{P(I)* P(L|I)}{ P(O) *P(L|O) + P(I) *P(L|I) }[/tex]

Where  [tex]P(I)[/tex] is the percentage that are from inside that country which is mathematically represented as

       [tex]P(I) = 1 - P(O)[/tex]

      [tex]P(I) = 1 - 0.70[/tex]

      [tex]P(I) = 0.30[/tex]

And [tex]P(L| O)[/tex] is  percentage that logs on everyday that are from the outside  the country which is evaluated as

      [tex]P(L| O) = 1- P(L| I)[/tex]

       [tex]P(L| O) = 1- 0.80[/tex]

       [tex]P(L| O) = 0.20[/tex]

[tex]P (I | L ) = \frac{ 0.3* 0.80 }{ 0.7 *0.20 + 0.3 * 0.8 }[/tex]    

[tex]P (I | L ) = 0.63[/tex]

Given that the percentage that are from inside that country is  [tex]P(I) = 0.30[/tex]

and that the probability that a person is from the country given that he logs on the website every day is  [tex]P (I | L ) = 0.63[/tex]

We see that the additional information increased the probability

Answer:

population of Fort Worth, Texas. =9/100(x)

Step-by-step explanation:

in the state of Texas, about 3/100 of the population lives in the city Fort Wroth.

Let the population of the state of texas = X

Fort wroth population= 3/100(x)

the population of Huston, Texas, is about 3 times the population of Fort Worth, Texas. = 3*(3/100(x))

the population of Huston, Texas, is about 3 times the population of Fort Worth, Texas. =9/100(x)

The fraction of the population of Texas that lives in Huston is 9/100x.

Let the population of Texas be represented by x.

Since the state of Texas is about 3/100 of the population lives in the city Fort Wroth and the population of Huston, Texas, is about 3 times the population of Fort Worth, Texas, then the fraction of the population of Texas lives in Huston will be:

= 3/100 × 3 × x

= 9/100 × x

The fraction of the population of Texas that lives in Huston is 9/100x.
