A diver is swimming at -10m. he then descends 3 m and rises 6 m. at what new level is the diver swimming?

Lets x and y are the value of two numbers.

x + y = 16

x - y = 2.4

If x + y = 16 then x = 16 - y

Substitute x = 16 - y into x - y = 2.4

16 - y - y = 2.4

16 - 2y = 2.4

2y = 13.6

 y = 6.8

x = 16 - y

x = 16 - 6.8

x = 9.2

Answer:

The value of two numbers are 9.2 and 6.8

To find (f+g)(x), add f(x) and g(x) together. (f + g)(x) is calculated as (5x - 2) + (2x + 1), which simplifies to 7x - 1. Therefore, the correct answer is C. 7x - 1.

The question asks to find the sum of two functions, f(x) and g(x).

To find (f+g)(x), we add the two functions together.

Here's how we calculate it:
First, we take the function f(x) = 5x - 2 and the function g(x) = 2x + 1.
Then, we add them together: (f + g)(x) = f(x) + g(x).
So, (f + g)(x) = (5x - 2) + (2x + 1).
Combining like terms, we get (f + g)(x) = 5x + 2x - 2 + 1.
This simplifies to (f + g)(x) = 7x - 1.

Therefore, the correct answer is C. 7x - 1.

Final answer:

To find (f+g)(x), we need to add the functions f(x) and g(x) together. The function f(x) is given as f(x) = 5x-2 and the function g(x) is given as g(x) = 2x+1. To add the functions, we simply add the coefficients of the variable and the constant terms. So, (f+g)(x) = (5x-2) + (2x+1) = 7x-1. Therefore, the correct answer is C. 7x-1.

Explanation:

To find (f+g)(x), we need to add the functions f(x) and g(x) together. The function f(x) is given as f(x) = 5x-2 and the function g(x) is given as g(x) = 2x+1.

To add the functions, we simply add the coefficients of the variable and the constant terms. So, (f+g)(x) = (5x-2) + (2x+1) = 7x-1. Therefore, the correct answer is C. 7x-1.

Here we are given the information that an insurance agent receives 16% commission on every premium paid.

Now we are given that a premium of $497.69 is paid.

Let us say $x is the commission paid on the policy with a premium of $497.69.

Let us try to find the amount x here.

So we have to find 16% of 497.69 to get the commission amount x.

So finding 16% of 497.69.

x= 16% of 497.69 = 0.16*497.69 = 79.63

Answer: Commission of $79.63 is paid on a policy with a premium of $497.69.

Answer:

$ 79.6304 of commission was paid on policy with a premium of $497.69.

:)

Using the formula, C = (F - 32) × 5/9, 41 degrees Fahrenheit is equal to 5 degrees Celsius.

To convert Fahrenheit (F) to Celsius (C), you can use the following formula:

C = (F - 32) × 5/9

In this formula, "F" represents the temperature in Fahrenheit, and "C" represents the temperature in Celsius.

Calculation:

Given temperature in Fahrenheit, F = 41°F

Plug the value of F into the formula:

C = (41 - 32) × 5/9

Now, perform the calculation:

C = 9 × 5/9

The 9 in the numerator and denominator cancel out, leaving us with:

C = 5

So, 41°F is equal to 5°C.

Answer:

NNN

Step-by-step explanation:

Let f = first lucky number, and let s = second lucky number.

Translate the sentences into two equations in two unknowns, and solve the system of equations to find the two unknowns.

"when I multiply my first number by 3 and my second lucky number by 2, the addition of the resulting produces a sum of 93."

3f + 2s = 93

"when I add twice my first lucky number to my second lucky number the sum is 53."

2f + s = 53

Now you have a system of equations.

3f + 2s = 93

2f + s = 53

Let's use the substitution method. Solve the second equation  for s.

s = 53 - 2f

Now we substitute 53 - 2f for s in the first equation.

3f + 2s = 93

3f + 2(53 - 2f) = 93

Distribute the 2.

3f + 106 - 4f = 93

Combine like terms on the left side.

-f + 106 = 93

Subtract 106 from both sides.

-f = -13

Divide both sides by -1.

f = 13

Now substitute f = 13 in the second original equation.

2f + s = 53

2(13) + s = 53

26 + s = 53

Subtract 26 from both sides.

f = 27

Answer: The first lucky number is 13, and the second lucky number is 27.

Since each shelf holds 9 books and the teacher has 55, you'll need to divide 55 ÷ 9 to find the number of shelves used. After dividing, you'll get 6.11. Round up the 6.11 to 7 since the teacher is using 6 shelves and a part of the seventh one.

The teacher fills 7 shelves with 55 books.

To find out how many shelves can be filled with 55 books where each shelf holds 9 books, simply divide 55 by 9. This gives approximately 6.11, but since you can't have a part of a shelf, we round down to 6.

The subject of this question is Mathematics, specifically division. To determine the number of shelves filled by the teacher, we should divide the total number of books by the number of books every shelf can hold. As given, the teacher has 55 books and each shelf holds 9 books.

So, you carry out the division: 55 ÷ 9. The answer is 6.111... Since we can't have a fraction of a shelf, we round this down to the nearest whole number. So, the teacher fills 6 shelves fully with books. Remember, this means there are some books that don't fill up a seventh shelf completely.

Hope this helped :)

Raul would ride 18 miles for 60 minutes at the same speed.

To find out how many miles Raul would ride for 60 minutes at the same speed, we can set up a proportion. If Raul rides 3 miles for 10 minutes, then we can say that 3 miles is to 10 minutes as x miles is to 60 minutes. Setting up this proportion, we get: 3/10 = x/60. To solve for x, we can cross multiply and then divide both sides by 10. This gives us: x = (3/10) * 60 = 18 miles.

To solve this you have to first find out how many 1000s are in 14000

There are 14 1000s in 14000 so now you multiply 15.68 by 14

15.68*14=219.52

so the answer is $219.52

Final answer:

Clem's monthly payment is $219.52.

Explanation:

To find Clem's monthly payment, we need to multiply the amount borrowed by the rate per $1000 borrowed. The rate is $15.68 for every $1000 borrowed. Clem borrowed $14000, so we divide $14000 by $1000 to find the number of $1000 increments. There are 14 $1000 increments in $14000.

Multiplying $15.68 by 14 gives us the monthly payment of $219.52.

Therefore his monthly payment is $219.52.

Step-by-step explanation:

We have been given a recurrence relation [tex]a_{n+1}=a_{n}+12[/tex] and the first term of the sequence [tex]a_{1}=4[/tex].

We can rewrite the given recurrence relation as: [tex]a_{n+1}-a_{n}=12[/tex]

We know that if difference between two consecutive terms is always constant, the sequence is called an arithmetic sequence. So we are dealing with an arithmetic sequence with first term as 4 and common difference as 12.

We can therefore, write an explicit formula for nth terms of the sequence as.

[tex]a_{n}=a_{1}+(n-1)d\\a_{n}=4+(n-1)(12)\\a_{n}=4+12n-12\\a_{n}=12n-8\\[/tex]

Answer: its 4.6

just took test

The y-coordinate for point A is approximately 4.6.

To find the y-coordinate of point A, we can use the Pythagorean theorem since we know the x-coordinate (-2) and the radius of the circle (5). The Pythagorean theorem states that the square of the hypotenuse is equal to the sum of the squares of the other two sides. In this case, the hypotenuse is the radius of the circle and the other two sides are the x and y coordinates. So we have:

x^2 + y^2 = r^2

Substituting the given values, we get:

(-2)^2 + y^2 = 5^2

Simplifying the equation, we have:

4 + y^2 = 25

y^2 = 21

Taking the square root of both sides, we get:

y ≈ ± 4.6

Since the point A lies in the upper half of the circle, the y-coordinate is positive. So the nearest tenth of the y-coordinate for point A is 4.6.

Part A.

You spend $6 per lawn and charge $35 per lawn, so the profit per lawn is $35 - $6 = $29. Let the number of lawns you mow be n. You earn a profit of $29 pewr laun, so you earn a profit of 29n for mowing n lawns.

29n = 450

Divide both sides by 29.

n = 450/29 = 15.517...

You must mow 16 lawns to make profit.

Part B.

3 lawns per day for 5 days per week means 15 lawns per week. Since you make a profit of $29 per lawn, you will make a profit of 15 * $29 for 15 lawns in each week. 15 * $29 = $435.

You want to make $2500 profit, but you must spend $450 on the lawn mower, so you need to earn a total of $2500 + $450 = $2950.

Let n be the number of weeks. In one week, you make $435 in profit. In n weeks, you make 435n in profit.

435n = 2950

Divide both sides by 435.

n = 6.7816...

If you work for 7 weeks, you will make at least $2500 in profit.

Since the summer vacation is longer than 7 weeks, it is a reasonable goal, but you must take into account the time it takes to mow three lawns in one day.

Solution

Here the first term = -2

5th term = -1/8

Now we have to find the common ratio (r)

Fifth term A5 = -1/8

-1/8 =[tex]a_{1} r^{4}[/tex]

Here [tex]a_{1} = -2[/tex]

Plug in [tex]a_{1}  = -2[/tex] in the fifth term and find the value of r.

-1/8 = -2[tex]r^{4}[/tex]

[tex]r^{4} = \frac{-1/8}{-2}[/tex]

[tex]r^{4} = \frac{1}{16}[/tex]

Taking 4th root, we get

r = [tex]\frac{1}{2}[/tex]

Now let's find the second term.

[tex]a_{2} =[/tex] first term *r = -2 *1/2 = -1

2nd term = -1

3rd term = second term * 1/2 = -1 * 1/2 = -1/2

4th term = 3rd term *r = -1/2 *1/2 = -1/4

Thank you :)

The 2nd term is  -1 , the 3rd term is [tex]\( -\frac{1}{2} \)[/tex], and the 4th term is [tex]\( -\frac{1}{4} \)[/tex].

To find the 2nd, 3rd, and 4th terms of the sequence, we need to determine the common ratio of the sequence since the given terms suggest it is a geometric sequence. A geometric sequence is a sequence of numbers where each term after the first is found by multiplying the previous one by a fixed, non-zero number called the common ratio.

Let's denote the first term of the sequence as [tex]\( a_1 \)[/tex] and the common ratio as r. The n-th term of a geometric sequence can be found using the formula:

[tex]\[ a_n = a_1 \cdot r^{(n-1)} \][/tex]

Given:

[tex]\[ a_1 = -2 \] \[ a_5 = -\frac{1}{8} \][/tex]

We can use the fifth term to find the common ratio r by plugging in the values into the formula for the n-th term:

[tex]\[ a_5 = a_1 \cdot r^{(5-1)} \] \[ -\frac{1}{8} = -2 \cdot r^4 \] \[ r^4 = \frac{-2}{-8} \] \[ r^4 = \frac{1}{4} \] \[ r = \pm\sqrt[4]{\frac{1}{4}} \] \[ r = \pm\frac{1}{2} \][/tex]

Since we are dealing with a sequence where the terms are decreasing in absolute value and changing sign (from negative to positive), we choose the positive value for r:

[tex]\[ r = \frac{1}{2} \][/tex]

Now we can find the 2nd, 3rd, and 4th terms:

[tex]\[ a_2 = a_1 \cdot r^{(2-1)} = -2 \cdot \left(\frac{1}{2}\right)^1 = -1 \] \[ a_3 = a_1 \cdot r^{(3-1)} = -2 \cdot \left(\frac{1}{2}\right)^2 = -\frac{1}{2} \] \[ a_4 = a_1 \cdot r^{(4-1)} = -2 \cdot \left(\frac{1}{2}\right)^3 = -\frac{1}{4} \][/tex]

The final answer is:

[tex]\[ a_2 = -1, \quad a_3 = -\frac{1}{2}, \quad a_4 = -\frac{1}{4} \][/tex]
