Answer:

(4x-7)(4x+7)

Step-by-step explanation:

This is called the Difference of Two Squares (DOTS).

These are the conditions that must be met for DOTS to work:

•There must be 2 terms.

•They must be separated by a negative sign.

•Each term must be a perfect square.

First, you have to find 2 square numbers that times together to make 16.

4×4=16

As we want 16x², you just need to make the 4 become 4x:

4x times 4x equals 16x²

Then, find 2 squares that times together to make 49.

7×7=49

You can put the two squares into a bracket with the x variable first, then the number:

(4x-7)(4x+7)

In the brackets, you always put the negative sign in the first one and then the plus sign in the second one.

You can double check your answer by expanding it back out again using FOIL:

F-First

O-Outer

I-Inner

L-Last

Times the First two in the two brackets:

4x times 4x equals 16x²

Times the Outer two:

4x times 7 equals 28x

Times the Inner two:

-7 times 4x equals -28x

Times the Last two:

-7 times 7 equals -49

Form an equation:

16x²+28x-28x-49

The 28x cancel out to leave:

16x²-49

Answer:

The solution for a is a =  \(\frac{P-b}{2}\)

Step-by-step explanation:

To solve an equation for one of its variables, do that

Let us solve the question

∵ The perimeter formula for an isosceles triangle is P = 2a + b

∵ We need to solve it for a

→ By using the first step above, subtract the two sides by b to move it

    from the right side to the left side

∵ P - b = 2a + b - b

∴ P - b = 2a

→ By using the second step above, divide both sides by 2

∵ \(\frac{P-b}{2}\) = \(\frac{2a}{2}\)

∴  \(\frac{P-b}{2}\) = a

→ Switch the two sides

∴ a =  \(\frac{P-b}{2}\)

∴ The solution for a is a =  \(\frac{P-b}{2}\)

Answer:

Step-by-step explanation:

To find the inverse of a matrix, we need to put it in the reduced row echelon form (RREF) using elementary row operations. We can augment the given matrix with an identity matrix of the same size, and then apply the row operations to both matrices simultaneously until the left-hand side becomes an identity matrix. The right-hand side will then be the inverse of the original matrix.

Here are the steps:

[ 5 3 | 1 0 ]

[13 8 | 0 1 ]

R1/5 -> R1:

[ 1 3/5 | 1/5 0 ]

[13 8 | 0 1 ]

R2-13R1 -> R2:

[ 1 3/5 | 1/5 0 ]

[ 0 1/5 | -13 1 ]

R1-(3/5)R2 -> R1:

[ 1 0 | 26/5 -3/5 ]

[ 0 1 | -13 1/5 ]

Step-by-step explanation:

After reducing all the book prices by 50%, the new median price is determined to be $7.70 (B)

To find the new median price after reducing all the book prices by 50%, we first need to calculate the reduced prices. By reducing each given price by 50%, we get $6.375, $7.40, $9.995, $4.975, $8.00, and $8.975 respectively.

Next, we arrange these reduced prices in ascending order: $4.975, $6.375, $7.40, $8.00, $8.975, and $9.995. The median is the middle value in this ordered list. Since there are six prices, the middle two values are $7.40 and $8.00.

To find the median, we take the average of these two values, which gives us ($7.40 + $8.00) / 2 = $7.70.

Therefore, the new median price, after reducing all the book prices by 50%, is $7.70 (B). This means that the median price of the books, after the reduction, is $7.70.

According to the question The tax for a house assessed at $160,000 would be $4,000.

To find the tax for a house assessed at $160,000 using the same tax rate, we can set up a proportion based on the assessed values and taxes paid:

\(\(\frac{\text{{Assessed value of house 1}}}{\text{{Tax paid for house 1}}}\) = \(\frac{\text{{Assessed value of house 2}}}{\text{{Tax for house 2}}}\)\)

Substituting the given values, we have:

\(\(\frac{120,000}{3,000} = \frac{160,000}{x}\)\)

Cross-multiplying and solving for \(\(x\)\), we get:

\(\(x = \frac{160,000 \times 3,000}{120,000}\)\)

Calculating the expression on the right side, we find:

\(\(x = \$4,000\)\)

Therefore, the tax for a house assessed at $160,000 would be $4,000.

The probability of picking a dime from the coins in his pocket is 1/13

1 penny = 1 cent

Hence, 100 pennies = $1

1 nickel = 5 cent

20 nickels = $1

1 dime = 10 cent

10 dime = $1

This means that :

Eduardo has :

Total coins = (100 + 20 + 10) = 130 coins

Recall :

Probability = required outcome / Total possible outcomes

P(dime) = number of dimes / total coins

P(dime) = 10 / 130 = 1/13

Hence, the probability of picking a dime = 1/13

The biggest decrease in waiting time between two consecutive eruptions is stored in the variable "biggest_decrease."

To find the biggest decrease in waiting time between two consecutive eruptions, we can create an array of waiting times for each eruption and calculate the differences between consecutive elements. Then, we can find the maximum value from those differences. Here's the code to accomplish this:

eruptions = [74, 62, ...]  

differences = [eruptions[i] - eruptions[i-1] for i in range(1, len(eruptions))]

biggest_decrease = abs(max(differences))

Make sure to replace the ellipsis (...) with the remaining waiting times for each eruption in the "eruptions" array. The variable "biggest_decrease" will store the absolute value of the biggest decrease in waiting time between two consecutive eruptions.

Part A: you can just restate parts of the text to make a vaild argument or you can make you own

Part B: he should measure N, O, P and Qas

Triangles MNO and QPO are congruent. To find the width of the creek, Andre should find the measurement of NP

When two triangles are congruent, their corresponding three sides and their three angles match precisely.

Given that

O is the midpoint of NP,

NP is perpendicular to MN, and

NP is perpendicular to PQ.

When two lines intersect at a specific point, the opposite angles formed in this situation are equal.

a) Then ∠MNP =∠QPO=90°

∠MON=∠QOP

Also, NO = OP (by the definition of midpoints)

Therefore, Triangles MNO and QPO are congruent by ASA rule

And,

b) To find the width of the creek, Andre should find the measurement of NP, because according to the figure the width is represented by NP. He should find NO and OP and then add it.

The dimensions of the rectangle which form the dining room is 7 by 5 meters.

The perimeter of the rectangle is 24 meters.

The total length of a shape's boundaries is its perimeter. The total lengths of all other edges and sides are added to find a shape's perimeter.

Let the length be a and the width be b.

Hence 2(a + b) = 24

or, a+b = 12

Now the area of the rectangle is given as 35 square meters.

Therefore ab = 35

now we will use these two equations to find the dimension of the rectangle

a+b = 12

or, a = 12 - b

again:

ab = 35

or, (12 - b)b = 35

or, 12 b - b² = 35

or,  - b² +12b -35 = 0

or,   b² - 12b + 35 = 0

or,  (b-7) (b-5) = 0

either b = 7 or b = 5 .

Therefore the value of a from the equations is 5 or 7.

Therefore the dimensions of the dining room are 7 by 5 meters.
