Answer:
[tex]f^{-1}(x)=\sqrt[3]{x}-1[/tex]
Step-by-step explanation:
[tex]f(x)=(x+1)^3\\\\y=(x+1)^3\\\\x=(y+1)^3\\\\\sqrt[3]{x}=y+1\\\\y=\sqrt[3]{x}-1\\ \\f^{-1}(x)=\sqrt[3]{x}-1[/tex]
Graphing both inverses, they will be symmetrical about the line [tex]y=x[/tex].
Bonds issued by Animite Energy are selling at a rate of 95. 230. Which of the following statements is true for a bond of par value $1,000? a. The market value includes a premium of $5. 23. B. The market value includes a premium of $10. 50. C. The market value includes a discount of $47. 70. D. The market value includes a discount of $95. 23.
The statements which is true for a bond of par value $1,000 is that the market value includes a discount of $47. 70.
What is market value?Market value is the current price of a product, company, or something consorting to the stock of the market.
It is the price which is required to buy something in the current market.
Bonds issued by Animite Energy are selling at a rate of 95.230. This is the bond percentage of the Animite energy in the market. This means if someone wants to buy 95.230 of this company's bond, then he get $100.
Now for the 1000 bonds, the amount required is,
[tex]C=95.230\times10\\C=952.30[/tex]
Hence, for the 1000 bonds, the amount required is 952.30. Therefore, the discount will be,
[tex]d=1000-952.30\\d=47.70[/tex]
Hence, the statements which is true for a bond of par value $1,000 is that the market value includes a discount of $47. 70.

Answer:
∠ 4 = 130°
Step-by-step explanation:
The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.
∠ 4 is an exterior angle of the triangle , so
∠ 4 = ∠ 1 + ∠ 2 ( substitute values )
11x + 9 = 6x + 6 + 4x + 14 , that is
11x + 9 = 10x + 20 ( subtract 10x from both sides )
x + 9 = 20 ( subtract 9 from both sides )
x = 11
Then
∠ 4 = 11x + 9 = 11(11) + 9 = 121 + 9 = 130°
your friend may have only calculated ∠ 1
∠ 1 = 6x + 6 = 6(11) + 6 = 66 + 6 = 72°

Answer:
a) 15.625 cm²
b) 8 cm²
c) 50 cm²
d) 12 cm²
Step-by-step explanation:
a) area of a parallelogram = base x height
⇒ area of yellow shape = 1/2 x base x height
= 1/2 x 12.5 x 2.5
= 15.625 cm²
b) area of triangle = 1/2 x base x height
= 1/2 x 2 x 8
= 8 cm²
c) area of a parallelogram = base x height
area yellow parallelogram = (10 x 6) - (5 x 2) = 50 cm²
d) area of a parallelogram = base x height
⇒ area of a 1/2 parallelogram = 1/2 x base x height
⇒ area yellow shape = 1/2 x 12 x 2 = 12 cm²
y=6x+2
y=3x+1
solve with substution
6x + 2 and 3x + 1 are both equal to y, so they are both equal to each other.
6x + 2 = 3x + 1
3x = -1
x = -1/3
And plugging -1/3 in for x yields y = 0.
Given that there are 3 feet or 36 inches in 1 yard, which of the following amounts is greater than 4 yards? Select all that apply.
A) 15 feet
B) 150 inches
C) 3 yards, 4 feet
D) 3 feet, 15 inches
E) 10 feet, 11 inches
Answer:
A B and C are correct

4 yards = 12 feet = 12x12 = 144 inches
A is correct since 15 feet > 12 feet
B is correct since 150 inches > 144 inches
C is correct since 3 yards + 4 feet = 4 yards and 1 foot > 4 yards
D is incorrect since 3 feet + 15 inches is 4 feet and 3 inches < 12 feet

What is mean by Triangle?A triangle is a three sided polygon, which has three vertices and three angles which has the sum 180 degrees.
Given that;
The figure is shown.
Let the unknown side = y
Now, For upper triangle, we can use Pythagoras theorem as;
⇒ 25² = y² + 16²
⇒ 625 = y² + 256
⇒ y² = 369
⇒ y = √369
⇒ y = 19.2
Hence, The value of x is find as by using Pythagoras theorem as;
⇒ 19.2² + x² = 22²
⇒ 368.6 + x² = 484
⇒ x² = 484 - 368.6
⇒ x² = 115.4
⇒ x = √115.4
⇒ x = 10.7 units

An urn contains 4 purple marbles and 3 pink marbles. Two marbles are drawn at random. What is the probability that both marbles are purple
if drawn with replacement?
Answer: 16/49
Step-by-step explanation:
The probability of pulling a purple marble is 4/7, since 4+3 is 7.
Since the marbles are replaced, the probability does not change when pulling out marbles.
To combine probabilities, we multiply them
[tex]\frac{4}{7} * \frac{4}{7} = \frac{16}{49}[/tex]

A store pays a 5% commission on the first $300 of a sale. If the sale is
greater than $300, the store pays a 9% commission on the amount
above $300. Which is the commission on a $900 sale?
Answer:
$69
Step-by-step explanation:
First, we want to focus on the first $300
Multiply 300 by 0.05 to get the commission
300 x 0.05 = 15
Now, we solve for the first 300, let's solve for the remaining sales, which is 600 because 900 - 300 = 600
Multiply 600 by 0.09
600 x 0.09 = 54
Add the two sales commission numbers together
15 + 54 = 69

A solid's volume is 10 cubic inches. The solid is dilated by a scale factor of 3.5. Kiran says, "I calculated the volume of the image as 35 cubic inches, but I don't think that's right."
A. What might Kiran have done wrong?
B. What is the volume of the image
Answer:
she forgot the exponent on 3.5^3
Step-by-step explanation:
10 x 3.5^3 = 428.7428.75 u^3
The term "dilation" refers to a transformation. The volume of the dilated cube is 428.75 in³.
What is dilation?The term "dilation" refers to a transformation that is used to downsize an item. Dilation is a technique for making items appear bigger or smaller. The picture produced by this transformation is identical to the original shape.
As it is given that the volume of the cube is 10 cubic inches, therefore, the side of the cube is,
[tex]\text{Volume of the cube} = a^3\\\\ 10 = a^3\\\\a =\sqrt[3]{10}[/tex]
Now, we know that dilation always applies to dimensions, therefore the new dimension of the dilated cube will be,
[tex]\text{Side of the dilated cube} = \sqrt[3]{10} \times 3.5\rm\ in[/tex]
Further, the volume of the dilated cube can be written as,
[tex]\rm \text{Volume of the Dilated cube} = Side^3\\\\[/tex]
[tex]= (\sqrt[3]{10} \times 3.5)^3\\\\ = (\sqrt[3]{10})^3 \times (3.5^3)\\\\= 10 \times 3.5^3\\\\= 10 \times 42.875\\\\= 428.75\rm\ in^3[/tex]
A.) The mistake that Kiran made is that she didn't take the cube of the scale factor.
B.) The volume of the dilated cube is 428.75 in³.

Which of the following probabilities is equal to approximately 0. 2957? Use the portion of the standard normal table below to help answer the question. Z Probability 0. 00 0. 5000 0. 25 0. 5987 0. 50 0. 6915 0. 75 0. 7734 1. 00 0. 8413 1. 25 0. 8944 1. 50 0. 9332 1. 75 0. 9599 P (negative 1. 25 less-than-or-equal-to z less-than-or-equal-to 0. 25) P (negative 1. 25 less-than-or-equal-to z less-than-or-equal-to 0. 75) P (0. 25 less-than-or-equal-to z less-than-or-equal-to 1. 25) P (0. 75 less-than-or-equal-to z less-than-or-equal-to 1. 25).
Probability of an event is the measure of its chance of occurrence. The event out of the listed events whose probability is 0.2957 is given by : Option C: [tex]P(0.25 \leq Z \leq 1.25)[/tex]
How to get the z scores?If we've got a normal distribution, then we can convert it to standard normal distribution and its values will give us the z-score.
If we have
[tex]X \sim N(\mu, \sigma)[/tex]
(X is following normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex] )
then it can be converted to standard normal distribution as
[tex]Z = \dfrac{X - \mu}{\sigma}, \\\\Z \sim N(0,1)[/tex]
(Know the fact that in continuous distribution, probability of a single point is 0, so we can write
[tex]P(Z \leq z) = P(Z < z) )[/tex]
Also, know that if we look for Z = z in z tables, the p-value we get is
[tex]P(Z \leq z) = \rm p \: value[/tex]
Using the z-table, we get the needed probabilities as:
Case 1:
[tex]P(-1.25 \leq Z \leq 0.25) = P(Z \leq 0.25) - P(Z \leq -1.25) \approx 0.5987 - 0.1056 = 0.4931[/tex]
Case 2:
[tex]P(-1.25 \leq Z \leq 0.75) = P(Z \leq 0.75) - P(Z \leq -1.25) \approx 0.7734- 0.1056=0.6678[/tex]
Case 3:
[tex]P(0.25 \leq Z \leq 1.25) = P(Z \leq 1.25) - P(Z \leq 0.25) \approx 0.8944 - 0.5987=0.2957[/tex]
Case 4:
[tex]P(0.75 \leq Z \leq 1.25) = P(Z \leq 1.25) - P(Z \leq 0.75) \approx 0.8944 - 0.7734 =0.1210[/tex]
Thus, the event out of the listed events whose probability is 0.2957 is given by : Option C: [tex]P(0.25 \leq Z \leq 1.25)[/tex]
