Answer:
| B | = - 9
Step-by-step explanation:
The determinant of a 2 by 2 matrix B = [tex]\left[\begin{array}{ccc}a&b\\c&d\\\end{array}\right][/tex] is
| B | = ad - bc
Then for
B = [tex]\left[\begin{array}{ccc}0&1\\9&8\\\end{array}\right][/tex]
| B | = (0 × 8 ) - (1 × 9 ) = 0 - 9 = - 9

Can someone please help me with this question
Please check this answer
Please tell me if it’s correct if it’s not please answer it correctly please
Step-by-step explanation:
Hey,
I'm sorry, this is not correct. For a reflection, all you have to do is count the number of points from that specific point to the line. So, for example, w is 6 units away from the line, in order to draw that, count 6 units and graph. It's pretty hard to explain, but remember the shape is being reflected, so the orientation must change. I suggest searching this up.
Let me know if you have any more questions and I'll be more than glad to help.

Tom needs to plow 1.1 acres of land. If he can plow 5.5 acres in an hour, how many hours will it take?
Help! (16 pts if you answer!)
Given:
Tom needs to plow 1.1 acres of land.
He can plow 5.5 acres in an hour.
To find:
The time taken by Tom to plow 1.1 acres of land.
Solution:
We have,
Time take by Tom to plow 5.5 acres = 1 hour
Time take by Tom to plow 1 acre = [tex]\dfrac{1}{5.5}[/tex] hour
Time take by Tom to plow 1.1 acres = [tex]\dfrac{1.1}{5.5}[/tex] hour
= [tex]0.2[/tex] hour
Therefore, the time taken by Tom to plow 1.1 acres of land is 0.2 hour.
area of a regular hexagon with an apothem of 15 cm
Answer:
area = 779.4 cm²
Step-by-step explanation:
divide it into 6 equal equilateral triangles. Each corner of a triangle will be 60°.
tan 60° = 15/x
1.7321 = 15/x
x = 8.66 (this is one-half of the base of the triangle)
base = 17.32 cm
area of one triangle = 1/2(17.32)(15) = 129.9 cm²
129.9(6) = 779.4 cm² (because 6 triangles make up the hexagon)

What is the length of segment AC?
Answer:
8 units
Step-by-step explanation:
Step-by-step explanation:
[tex]C = ( - 6,5) \: and \:A = (3, - 1) \\ length \: AC = \sqrt{ {(x _{2} - x _{1}) }^{2} + {(y _{2} - y _{1})}^{2} } \\ AC = \sqrt{ {(3 - ( - 6))}^{2} + {( - 1 - 6)}^{2} } \\ AC = \sqrt{(81 + 49)} \\ AC = \sqrt{130} \\ AC = 11.4[/tex]

How many quart are 8/1/4 gallons
Given:
Consider the given gallons are [tex]8\dfrac{1}{4}[/tex] gallons.
To find:
The number of quarts in [tex]8\dfrac{1}{4}[/tex] gallons.
Solution:
We know that,
1 gallons = 4 quarts
Using this conversion, we get
[tex]8\dfrac{1}{4}\text{ gallons}=4\times 8\dfrac{1}{4}\text{ quarts}[/tex]
[tex]8\dfrac{1}{4}\text{ gallons}=4\times \dfrac{32+1}{4}\text{ quarts}[/tex]
[tex]8\dfrac{1}{4}\text{ gallons}=4\times \dfrac{33}{4}\text{ quarts}[/tex]
[tex]8\dfrac{1}{4}\text{ gallons}=33\text{ quarts}[/tex]
Therefore, there are 33 quarts in [tex]8\dfrac{1}{4}[/tex] gallons.

Javier estimates the square root of 18 in the following way:
√18=2√9=2*3=6
A: Explain why her reasoning is incorrect.
B: Without using a calculator, the square root of 18 will be between what two values (remember to look for perfect squares/perfect square roots)? Show your reasoning. You do not need to find the decimal equivalent of the root.
Step-by-step explanation:
√18 = √(2x9) = 3√2. so they pulled the 2 out of the square root incorrectly.
4x4 = 16
5x5 = 25
so √18 is between 4 and 5. closer to 4
Look at the question below!
Answer:
the answer is 5 miles per hour
Step-by-step explanation:
because the difference between 125 and 250 is 125 and you know that's you rate of change. so we know 0 in time would also be 0 in distance. but since it's one you divide 125 by 5 = 25

Algebra 2 will give points and brainly
Answer:
Step-by-step explanation:
In the 3rd question, we are given the equation x ^ 3 + x ^ 2 + 2x + 24. One of the factors is x + 3. Now, we can use long division to find that the equation we have left is x^2 - 2x - 8. We can just factor this to get (x - 4) (x + 2). In the 3rd question, possible factors for the coefficient are 1, 2, -1, -2. Possible factors for the constant are 1, 7, -1, -7. Now, we can try out all of them. The possible factors are 1, 7, -1, -7, 2, 14, -2, -14.

The Albertsons are purchasing a home for $400,000. They are financing 70 percent of the home’s value. In addition to the down payment, they have the following closing costs:
Lender’s inspection fee $400
Loan origination fee 1.5% of the loan amount
Notary public fee $60
Document recording fees $75
Title search $300
What is the total amount of the closing costs?
Answer:
$5,035
Step-by-step explanation:
First, you have $400 as the first cost in the closing costs.
You Then find 1.5% of the loan amount, which is 70% of $400,000 ($280,000), so 1.5% of $280,000 is $4,200. So you add $4,200 to the $400
Next, you add the notary fee of $60.
Then you add the recording fees of $75.
Lastly, you add the title search of $300.
Now add everything up, $400 + $4,200 + $60 + $75 + $300 = $5,035
Final answer = $5,035
