14.4 A Book and a Cake A book costs $45. Sales tax on the book is 7%. Write two different expressions that represent the final cost of the book in dollars. Pne of the expressions should use only a single multiplication and no other operations.
A cake that costs $32 is on sale for 15% off and there are no taxes. Explain why the expression (0.85).32 represents the final price of the cake in dollars
(0.85). 32 represents the final price of the cake in dollars because...
Answers
Answer: 1. $45*1.07 | $45(1.07) 2. (0.85)*32 represent the final price of the cake in dollars because (0.85) is the 15% off in decimals.
Step-by-step explanation:
1 if you multiply 45 by 1.07 it will be 48.15 and that's the final cost of the book, same with $45(1.07) is just another way to represent the multiplication.
2 As I said the 0.85 represent the 15% off, and when you multiply it will be less.
Which of the following statements are true about inverse matrices?
All square matrices have inverses.
If A and B are inverse matrices, then A and B must be square matrices.
The determinant of a singular matrix is equal to zero.
If A and B are inverse matrices, then A + B = I.
If A and B are inverse matrices, then det(A)xde(B)=0
Any zero matrix does not have an inverse.
If B = A–1, then A = B–1.
Answers
B = A–1, then A = B–1. This statement is true. The inverse of a matrix is unique, so if B is the inverse of A, then A must be the inverse of B.
what is matrix ?An arrangement of integers in both columns and rows is known as a matrix. learns about matrices' components and dimensions and first presents them. A matrix is a rectangular grid with integers arranged in rows and columns.
The statements that are true about inverse matrices are:
Not all square matrices have inverses. A square matrix only has an inverse if its determinant is not equal to zero. If the determinant of a square matrix is zero, it is called a singular matrix and does not have an inverse.
If A and B are inverse matrices, then A and B must be square matrices. This is because only square matrices can have inverses.
The determinant of a singular matrix is equal to zero. This is because the determinant of a matrix is related to the linear independence of its columns or rows. A singular matrix has linearly dependent columns or rows, which means its determinant is zero.
If A and B are inverse matrices, then A + B = I. This is not necessarily true. In general, the sum of two inverse matrices is not necessarily the identity matrix.
If A and B are inverse matrices, then det(A) x det(B) = 1. This statement is almost true, but the correct statement is det(A) x det(B) = det(AB) = 1.
Any zero matrix does not have an inverse. This is because the determinant of a zero matrix is zero, and therefore it is singular and does not have an inverse.
If B = A–1, then A = B–1. This statement is true. The inverse of a matrix is unique, so if B is the inverse of A, then A must be the inverse of B.

The drawing below represents a 22-foot ladder with its base placed 10 feet from the bottom of a vertical wall. whatis the best value for x
Answers
Answer:
x = 62.96°
Step-by-step explanation:
From the attached figure,
Base, b = 10 ft
Hypotenuse, H = 22 ft
We need to find the value of x. We can use trigonometry to find it.
We know that,
[tex]\cos\theta=\dfrac{B}{H}[/tex]
Putting all the values,
[tex]\cos x=\dfrac{10}{22}\\\\x=62.96^{\circ}[/tex]
So, the value of x is 62.96°.

If f(x)= -2x+3 , find f(-1)?
Answers
Before we solve the equation let's take a look at it.
f(x) = -2x + 3
See how x appears in both f(x) and as the variable in the second half of the equation?
f(x) means "The function of x." You might also see g(x), h(x), and while those are the most common it can really be any letter, and any variable inside the parentheses.
So when we see f(-1), that means "The function of -1" or "The function of x when it is equal to -1."
Catching on? We need to replace x with -1 to solve for f(-1).
So here we go:
f(x) = -2x + 3
f(-1) = -2(-1) + 3
f(-1) = 2 + 3
f(-1) = 5
Voilà! We have solved for f(-1). Hope this helped.

a bus accelerates from 2 m/s to 10 m/s in 5 seconds. What was its average acceleration?
Please Help
Answers
Answer:
I believe the answer is 4. Please correct me if I’m wrong.
Step-by-step explanation:
================================================
Work Shown:
A = old velocity = 2 m/s
B = new velocity = 10 m/s
C = change in time = 5 seconds
D = average acceleration
D = (change in velocity)/(change in time)
D = (B-A)/C
D = (10-2)/5
D = 8/5
D = 1.6 m/s^2
The acceleration 1.6 m/s^2 means that the velocity is increasing by 1.6 m/s for every second.
