For A I somehow got 41.05 but its 2.95cm can someone show me the working and what I did wrong?

Answer:

7.80%

Step-by-step explanation:

Given data

Amount borrowed=$3,209

Payback amount= $4,210.21

Simple interest= 4,210.21-3,209= 1001.21

time= 4 years

We know that

SI= PRT/100

1001.21= 3,209*R*4/100

cross multiply

1001.21*100= 12836R

100121/ 12836= R

R=7.80

Hence the rate is 7.80%

Answer:

(-1)

Since it is a downward slope with two equalized points x=7 and y=7. The slope is m = -1.

Answer:

d.1

Step-by-step explanation:

For this question, use change in y value from one point to another over change in x value from one point to another.

Answer:

See explanations below

Step-by-step explanation:

Given the function

f(x) = 3x+12

Let y = f(x)

y = 3x+12

Replace y with x

x = 3y+12

Make y the subject

3y = x-12

y = (x-12)/3

Hence the required inverse is!

g(x) = (x-12)/3

b) To show that the functions are inverses, we must show that f(g(x)) = g(f(x))

f(g(x)) = f((x-12)/3)

Replace x in f(x) with x-12/3

f(g(x)) = 3(x-12)/3 +12

f(g(x)) = x-12+12

f(g(x)) = x

Similarly for g(f(x))

g(f(x)) = g(3x+12)

g(f(x)) = (3x+12-12)/3

g(f(x)) = 3x/3

g(f(x)) = x

Since f(g(x)) = g(f(x)) = x, hence they are inverses of each other

c) Given f(g(x)) = x

f(g(–2)) = -2

The domain is the input variable of the function. Hence the domain is -2

Answer: [tex]\dfrac{5}{14}[/tex]

Step-by-step explanation:

Given: An urn contains 3 red and 5 orange marbles.

Total marbles = 3+5=8

Probability of getting orange marble = [tex]\dfrac{\text{Number of orange marble}}{\text{Total}}[/tex]

[tex]=\dfrac{5}{8}[/tex]

Now marbles left = 7

Orange marbles left = 4

and Probability of getting orange marble = [tex]\dfrac47[/tex]

The probability that the second marble selected is orange given that the first marble selected is orange[tex]=\dfrac58\times\dfrac47=\dfrac{5}{2}\times\dfrac17=\dfrac{5}{14}[/tex]

Required probability= [tex]\dfrac{5}{14}[/tex]

Answer:

Hence, Suzanne is working at a faster rate.

Suzanne started with the most windows already installed

Step-by-step explanation:

Number of windows he's installing :

Tom's equation :

y = 7x + 2

Suzanne's equation :

y = 6x +5

x = number of days used

Let y = 10

Tom:

10 = 7x + 2

10 - 2 = 7x

8 = 7x

x = 8/7 ; x = 1.143

Suzanne :

y = 6x + 5

10 = 6x + 5

10 - 5 = 6x

5 = 6x

x = 5/6

x = 0.833

Since 0.833 < 1. 143

Hence, Suzanne is working at a faster rate.

Intercept in Suzanne's equation = 5

Intercept in Tom's equation = 5

Suzanne started with the most windows already installed

Answer:

Domain: (-∞, ∞) or All Real Numbers

Range: (0, ∞)

Asymptote: y = 0

As x ⇒ -∞, f(x) ⇒ 0

As x ⇒ ∞, f(x) ⇒ ∞

Step-by-step explanation:

The domain is talking about the x values, so where is x defined on this graph? That would be from -∞ to ∞, since the graph goes infinitely in both directions.

The range is from 0 to ∞. This where all values of y are defined.

An asymptote is where the graph cannot cross a certain point/invisible line. A y = 0, this is the case because it is infinitely approaching zero, without actually crossing. At first, I thought that x = 2 would also be an asymptote, but it is not, since it is at more of an angle, and if you graphed it further, you could see that it passes through 2.

The last two questions are somewhat easy. It is basically combining the domain and range. However, I like to label the graph the picture attached to help even more.

As x ⇒ -∞, f(x) ⇒ 0

As x ⇒ ∞, f(x) ⇒ ∞

Answer:

-24

Step-by-step explanation:

We are given two equations and are asked to solve if one equals a certain amount to the other.

Let's focus on x + 3 = 13, we need to first figure out what is x. Which is very simple, what plus 3 equals 13?

10 of course, therefore x = 10, and we can implement into the other equation.

5x - 74

Since x = 10, we can substitute x with 10 and then multiply.

5(10) - 74

50 - 74

What is 50 - 74?

Answer:

  41.4

Step-by-step explanation:

The Law of Cosines tells you ...

  a² = b² +c² -2bc·cos(A)

where sides a, b, c are opposite angles A, B, C, respectively. Filling in the given numbers, you have ...

  a² = 30² +26² -2·30·26·cos(95°)

  a² ≈ 1711.96

  a ≈ √1711.96 ≈ 41.38

The length of BC is about 41.4 units.

Answer:

[tex]TU = 15[/tex]

Step-by-step explanation:

Given

[tex]\square MNOP \simeq\ \square STUV[/tex]

[tex]NO = 10[/tex]

[tex]OP = 4[/tex]

[tex]TU = x[/tex]

[tex]UV = 6[/tex]

Required

Determine the length of TU (i.e. x)

Because both shapes are similar, then the following equivalent ratios exist:

[tex]NO : OP = TU : UV[/tex]

Substitute values for NO, OP, TU and UV

[tex]10 : 4 = x : 6[/tex]

Represent as fraction

[tex]\frac{10 }{ 4 } = \frac{x }{ 6}[/tex]

Multiply both sides by 6

[tex]6 * \frac{10 }{ 4 } = \frac{x }{ 6} * 6[/tex]

[tex]6 * \frac{10 }{ 4 } = x[/tex]

[tex]x = 6 * \frac{10 }{ 4 }[/tex]

[tex]x = \frac{60 }{ 4 }[/tex]

[tex]x = 15[/tex]

Hence:

[tex]TU = 15[/tex]
