Is a²b the same thing as ba² ?

Please explain. Thanks so much!

Answers

Answer 1

a²b is the same thing as ba²

b and a are two separate variables lets pretend a is 2 and b is 3

2² * 3 = 4 * 3 = 12

3 * 2² = 3 * 4 = 12

this is the commutative property of multiplication

Answer 2

An expression is defined as a set of numbers, variables, and mathematical operations. The two of the given expressions a²b and ba² are the same.

What is an Expression?

In mathematics, an expression is defined as a set of numbers, variables, and mathematical operations formed according to rules dependent on the context.

The two of the given expressions a²b and ba² are the same because if the two of the expressions are expanded then the value of the two expressions will be equal to each other.

Therefore, the two expressions are expanded as shown below,

a²b = a × a × b

ba² = b × a × a

Therefore, the two of the given expressions a²b and ba² are the same.

Which choice could be used in proving that the given triangles are similar?

Answers

Answer: . To prove triangles are similar, you need to prove two pairs of corresponding angles are congruent

Step-by-step explanation:

SSS similarity postulate

The SSS similarity postulate says that if the lengths of the corresponding sides of two triangles are proportional then the triangles must be similar.

In the given figure , we have two triangles ΔABC and ΔXYZ such that the corresponding sides of both the triangles are proportional.

i.e.

Then by SSS-similarity criteria , we have

ΔABC ≈ ΔXYZ

Answer:

Step-by-step explanation:

tan(16)=125/a

tan(16)=35.8 (DC)

tan(7)=125/a

tan(7)=15.3

35.8-15.3=20.5

Sorry if that's incorrect, my best is 20.5 feet.

Answer:   approximately 582 feet.

======================================================

Work Shown:

Let

x = length of AD in feet

y = length of DC in feet

x and y are positive real numbers.

For now, focus on triangle BCD. Ignore point A and its associated angle.

tan(angle) = opposite/adjacent

tan(D) = BC/DC

tan(16) = 125/y

y*tan(16) = 125

y = 125/tan(16)

y = 435.926805480113

y = 435.926805

The value of y is approximate

Now focus on triangle ABC. Ignore point D and its associated angle.

tan(angle) = opposite/adjacent

tan(A) = BC/AC

tan(A) = BC/(AD+DC)

tan(7) = 125/(x + y)

(x+y)*tan(7) = 125

x*tan(7) + y*tan(7) = 125

x*tan(7) = 125 - y*tan(7)

x = ( 125-y*tan(7) )/( tan(7) )

x = ( 125-435.926805*tan(7) )/( tan(7) )

x = 582.116498496824

x = 582

The distance from A to D is approximately 582 feet.

Answer:

The number of yards in 5 miles will be: 8800 miles

Step-by-step explanation:

The double numbers line shows the ratio of yards to miles.

From the number line, it is clear that

at 2 miles, the number of yards is 3520.

Thus,

The unit rate = 3520 yards / 2 miles

                      = 1760 yards / per mile

Thus, the number of yards in 5 miles will be:

1760 × 5 = 8800 miles

Therefore, the number of yards in 5 miles will be: 8800 miles

3200 dollars is placed in an account with an annual interest rate of 8.25%. To the
nearest tenth of a year, how long will it take for the account value to reach 9600
dollars?

Hello, I come from the deltamath past to help you, in the deltamath future. It’s 13.9

Answers

It takes 24 years for the account value to reach the $9600.
Step-by-step explanation:
From the given data, it can be determined that :
Amount = $9600
Principal = $3200
Rate = 8.25% = 0.0825
Number of years should be calculated.
To find the interest :
Amount = Principal + Interest
Therefore, the interest can be calculated by the formula,
Interest = Amount - Principal
⇒ 9600 - 3200
⇒ 6400
The interest needed is 6400.
To find the number of years required to reach this interest :
Use the formula for simple interest,
Simple interest = Pnr /100
where,
P is the principal
n is the number of years
r is the rate
Substitute all the given values in the simple interest formula,
Simple interest = 3200 × n × 0.0825
6400 = 264 n
n = 6400 / 264
n = 24.2 which is approximately 24 years.
Therefore, it takes 24 years for the account value of 3200 dollars to reach 9600 dollars.

Step-by-step explanation:

-Factoring by grouping-

First, split the middle term into two parts that are factorable by the other variables.

Factor the parts

x · ( x + 1 ) + 5 · ( x + 1 )

( x + 5 ) · ( x + 1 )

Answer:

C

Step-by-step explanation:

Given

x² + 6x + 5

Consider the factors of the constant term (+ 5) which sum to give the coefficient of the x- term (+ 6)

The factors are + 1 and + 5 , since

1 × 5 = + 5 and 1 + 5 = + 6, thus

x² +6x + 5 = (x + 1)(x + 5) → C
