Step-by-step explanation:

[tex] \sf \sqrt{7 - 3z} = 3 + cz \\ \\ \sf z = 2 [/tex]

We will just substitute the value of z in the equation

[tex] \sf \implies \sqrt{7 - 3(2)} = 3 + c(2) \\ \\ \sf \implies \sqrt{7 - 6} = 3 + 2c \\ \\ \sf \implies \sqrt{1} = 3 + 2c \\ \\ \sf \implies 1 = 3 + 2c \\ \\ \sf \implies 1 - 3 = 2c \\ \\ \sf \implies - 2 = 2c \\ \\ \sf \implies \frac{ - 2}{2} = c \\ \\ \sf \implies \large \red{ \mathfrak{ - 1 = c}}[/tex]

Colleen has put $26,000 into a retirement fund. the fund has an estimated annual return of 10%. if colleen doesn't add any more money, how much can she expect to have in the fund in 7 years?

if necessary, round your answer to the nearest cent

the answer is : 50,666.64

Answers

Using an exponential function, it is found that she can be expected to have $50,666.64 in the fund in 7 years.

What is an exponential function?

An increasing exponential function is modeled by:

[tex]A(t) = A(0)(1 + r)^t[/tex]

In which:

A(0) is the initial value.r is the decay rate, as a decimal.

In this problem, we have that the initial amount and the growth rate are given, respectively, by:

A(0) = 26000.r = 0.1.

Hence the amount after t years is given by:

[tex]A(t) = 26000(1.1)^t[/tex]

Then, after 7 years, the amount is:

[tex]A(7) = 26000(1.1)^7 = 50,666.64[/tex]

QR is the radius of R and PQ is the tangent to R. Find the value of x.

Answers

Answer:

x = 39

Step-by-step explanation:

We know that PRQ is a right triangle, so we use the pythagorean theorem to solve the problem. The theorem states that a^2 + b^2 = c^2. Let's assume that the length of RP is c, the length of PQ is a and x is b. We plug the lengths into the equation and solve it:

80^2 + x^2 = 89^2

6400 +x^2 = 7921

x^2 = 1521

x = [tex]\sqrt{1521}[/tex]

x = 39

The solution of the rational equation [tex]\frac{3}{a + 2} * \frac{2}{a} = \frac{4 a - 4 }{a^2 - 4}[/tex] is a = 3

How to determine the solution?

The equation is given as:

[tex]\frac{3}{a + 2} * \frac{2}{a} = \frac{4 a - 4 }{a^2 - 4}[/tex]

Express a^2 - 4 as  a difference of two squares

[tex]\frac{3}{a + 2} * \frac{2}{a} = \frac{4 a - 4 }{(a + 2)(a - 2)}[/tex]

Cancel out the common terms

[tex]\frac{3}{} * \frac{2}{a} = \frac{4 a - 4 }{a - 2}[/tex]

Factor out 2 from 4a - 4

[tex]\frac{3}{} * \frac{2}{a} = \frac{2(a - 2) }{a - 2}[/tex]

Evaluate the quotient

[tex]\frac{3}{} * \frac{2}{a} = 2[/tex]

Divide both sides by 2

[tex]\frac{3}{1} * \frac{1}{a} = 1[/tex]

Cross multiply

a = 3

Hence, the solution of the equation [tex]\frac{3}{a + 2} * \frac{2}{a} = \frac{4 a - 4 }{a^2 - 4}[/tex] is 3

Ravi buys lunch at a restaurant.

An 8% sales tax is added, and he tips the waiter 20% of the cost of the food.

Ravi pays a total of $17.92 for his lunch, including tax and tip.

What is the price of Ravi's lunch, before tax and tip?

Answers

The price of Ravi's lunch, before tax and tip was added to the total cost of the meal is $13.19.

What is the price of the lunch?

Both the tax and the tip paid would increase the cost of the meal. Thus, their dollar value has to be subtracted from the total amount he pays.

Value of the lunch after the tip has been removed = (1 - 0.2) x 17.92 = $14.34

Value of the lunch after the tax has been removed = (1 - 0.08) x $14.34 = $13.19

Answer:

b = 17

Step-by-step explanation:

The correct equation is 3b - 6 = 45. You get this by saying the books (b) are 3 dollars each (3b) and you are getting a discount of 6 dollars off (- 6). The total after the discount is 45 dollars. You know have to solve this equation for b (the number of books) to get the answer. When you solve this equation, you get b = 17.

Answer:

3b - 6 = 45 and b = 17

Step-by-step explanation:

3b - 6 = 45 is your equation you get

3b is how many books you bought and the price multiplied by one another, then subtracting 6 gives you the discounted price which is 45

3b - 6 = 45

+6          +6

3b = 51

/3     /3

b = 17

a book costs 17 dollars.

so b = 17

Answers

The answer is G. Think of the variable y as each additional copy. 12 times (y- # of additional copies). 15 is the starting pay of the first copy so you only need to pay 15 once. However, 12 depends on how many additional copies you have which is our missing number y

Answer:

The term, "variability" describes how far apart data points lie from each other, and from the center of a distribution.

Along with measures of central tendency, measures of variability give you descriptive statistics that summarize your data.

Hey there!

In order to find the area of this triangle, we need to find the base and height of the triangle

the base of the triangle is 7 units long and the height of the triangle is 4 units high

Formula for area of triangle: Base x Height x 1/2

7 x 4 x 1/2 --> 28 x 1/2 --> 14

So, the area of this triangle is 14

Now the question is asking to find the area by forming a parallelogram

All you have to do for this is duplicate that same triangle, and mirror it upside down

Then all you would have to do is find the Base and the Height and multiply them together
