Help!!!! 10 points Taking a test Micah invested $3450 in an account paying simple interest. At the end of 6
years, the value of his account was $3967.50. What was the interest rate? *
O a. 1.5%
O b. 2.0%
O c. 2.5%
O d. 15%

Answers

Answer 1

Answer:

The answer is C.

Step-by-step explanation:

First, you have to find the interest amount after 6 years. In order to do this, you have to subtract :

[tex]3967.50 - 3450 = 517.50[/tex]

Next, you have to apply simple interest formula, I = (P×R×T)/100 where I repesents interest amount, P is priciple, R is interest rate and T is number of years :

[tex]i = \frac{prt}{100} [/tex]

[tex]let \: i = 517.50,p = 3450,t = 6[/tex]

[tex]517.50 = \frac{3450 \times r \times 6}{100} [/tex]

[tex]517.50 = \frac{20700r}{100} [/tex]

[tex]51750 = 20700r[/tex]

[tex] \frac{51750}{20700} = r[/tex]

[tex]r = 2.5\%[/tex]

what is the formula for 1, -3, 9, -27?
arithmetic or geometric?

Answers

Answer:

The formula of the geometric sequence is a[tex]_{n}[/tex] = [tex](-3)^{n-1}[/tex]

Step-by-step explanation:

The terms of the sequence are 1, -3, 9, -27

∵ -3 ÷ 1 = -3

∵ 9 ÷ -3 = -3

∵ -27 ÷ 9 = -3

∴ There is a common ratio between each two consecutive terms

The sequence is geometric

∵ The formula of the geometric sequence is a[tex]_{n}[/tex] = a [tex]r^{n-1}[/tex], where

a is the first term r is the common ratio

∵ The first term is 1

a = 1

∵ The common ratio is -3

r = -3

→ Substitute them in the formula above

∵ a[tex]_{n}[/tex] = (1) [tex](-3)^{n-1}[/tex]

∴ a[tex]_{n}[/tex] = [tex](-3)^{n-1}[/tex]

The formula of the geometric sequence is a[tex]_{n}[/tex] = [tex](-3)^{n-1}[/tex]

The second plan has an initial fee of and costs an additional per mile driven. How many miles would Tom need to drive for the two plans to cost the same?

Answers

Complete question :

Tom will rent a car for the weekend. He can choose one of two plans. The first plan has an initial fee of $57.98 and costs an additional $0.14 per mile driven. The second plan has an initial fee of $53.98 and costs an additional $0.16 per mile driven. How many miles would Tom need to drive for the two plans to cost the same?

Answer:

200 miles

Step-by-step explanation:

Let miles driven = x

First option :

57.98 + 0.14x

Second option :

53.98 + 0.16x

First option = second option

57.98 + 0.14 = 53.98 + 0.16x

57.98 - 53.98 = 0.16x - 0.14x

4 = 0.02x

x = 200

200 miles

Step-by-step explanation:

1. Use the Pythagorean theorem: a^2+b^2=c^2.

You are already given c (which is always the longest side of the triangle) and one of the legs, which can be either a or b.

2. Put the numbers into the equation and square them.

6^2+b^2=10^2

When you square the numbers, it becomes 36 + b^2 = 100.

3. Subtract 36 from both sides and take the square root of the difference.

b^2 = 64

[tex]\sqrt{64}[/tex] = 8

Answer: 8cm

Step-by-step explanation: Let’s use the Pythagorean Theorem! 6^2+x^2=10^2

36+x^2=100

Answer:

  A, C

Step-by-step explanation:

The domain is the list of x-values in the table. Choice A correctly lists the domain values.

The range is the list of y-values in the table. Choice B incorrectly describes the domain.

For x = -1, the table tells you f(x) = 6, so f(-1) = 6.

For x = 5, the table tells you f(x) = 12, so f(5) = 12, not -2.

Choices A and C are correct.

What is a quadratic function?

A polynomial function with one or more variables, where the largest exponent of the variable is two, is referred to as a quadratic function. In other terms, a "polynomial function of degree 2" is a quadratic function.

We can start by completing the square of the quadratic function g(k) = -k² + 6k - 9:

g(k) = -(k² - 6k + 9 ) = -(k - 3)²

Option A can be simplified as:

g(k) = -(k - 3)²

Compared with the completed square form of g(k), we can see that option A is equivalent to g(k).

Therefore, the answer is A. g(k) = -(k - 3)²

Answers

Answer:

(fog)(x)  = 5x+45(gof)(x)   = 5x+9(fog)(3) = f(g(3)) = f(12) = 60    

Step-by-step explanation:

Given

f(x) = 5xg(x) = x + 9

Finding (fog)(x)

(fog)(x)  = f(g(x))

(fog)(x)  = f(x+9)

(fog)(x)  = 5(x+9)             ∵ substitute x as x+9 in the f(x)

(fog)(x)  = 5x+45

Finding (gof)(x)

(gof)(x) = g(f(x))

(gof)(x)  = g(5x)

(gof)(x)   = 5x+9                 ∵ substitute x as 5x in the g(x)

Finding (fog)(3)

(fog)(3) = f(g(3))

substitute x = 3 in the g(x)=x+9

g(x) = x+9

g(3) = 3+9

g(3) = 12

so

(fog)(3) = f(g(3)) = f(12)

now substitute x = 12 in  f(x) = 5x

f(x) = 5x

f(12) = 5(12)

f(12) = 60

Thus,

(fog)(3) = f(g(3)) = f(12) = 60

In a music competition, a participant has to score a total of 40 points in the first four rounds combined to move on to the 5th and final round. Glen scored 4 points in the first round. He then went on to score additional points in the second, third and forth rounds. In each round he scored the identical points. Which inequality shows the number of points Glen scored.

Answers

Answer:

x ≥ 12

Step-by-step explanation:

Given that :

Total points required = 40

1st round point = 4

2nd, 3rd and 4th round points are identical

Let the point number of points = x

2nd + 3rd + 4th = 3

1st round + 3(x) ≥ 40

4 + 3x ≥ 40

3x ≥ 40 - 4

3x ≥ 36
