(2x + 1)(x - 2)(x + 3)
Answer:
Answer is =2x^3+3x^2-11x-6
Step-by-step explanation:
First of all multiply first and second bracket.
=x(2x+1) -2(2x+1)
=2x^2+x-4x-2
=2x^2-3x-2
Now multiply 2x^2-3x-2 with (x+3)
=x(2x^2-3x-2) +3(2x^2-3x-2)
=2x^3-3x^2-2x+6x^2-9x-6
=2x^3+3x^2-11x-6
The expansion and simplification of the expression (2x + 1)(x - 2)(x + 3) is 2x^3 + 3x^2 - 11x - 6.
Explanation:To expand and simplify the expression (2x + 1)(x - 2)(x + 3), we use the distributive property (a(b + c) = ab + ac) to distribute each term of one binomial with each term of the others.
We start by expanding the first two brackets : (2x + 1)(x - 2). This gives 2x^2 - 4x + x - 2 or, 2x^2 - 3x - 2.
Now, we expand the above result with (x + 3): (2x^2 - 3x - 2)(x + 3) yielding 2x^3 - 3x^2 - 2x + 6x^2 - 9x - 6.
When we simplify that, we get : 2x^3 + 3x^2 - 11x - 6. So, the expansion and simplification is : (2x + 1)(x - 2)(x + 3) = 2x^3 + 3x^2 - 11x - 6.

Step-by-step explanation:
Since the triangle is right using the cosine ratio to solve for BC
noting that the exact value of cos45° = [tex]\frac{1}{\sqrt{2} }[/tex], so
cos45° = [tex]\frac{BC}{AC}[/tex] = [tex]\frac{BC}{n}[/tex]
Multiply both sides by n

n × [tex]\frac{1}{\sqrt{2} }[/tex] = BC
[tex]\frac{n}{\sqrt{2} }[/tex] × [tex]\frac{\sqrt{2} }{\sqrt{2} }[/tex] = BC
Hence BC = [tex]\frac{n\sqrt{2} }{2}[/tex] → D
The right-angle triangle is given with one angle of 45 degrees. The length of segment BC is n√2/2.
What is the right triangle?A right-angle triangle is a triangle that has a side opposite to the right angle the largest side and is referred to as the hypotenuse.
The angle of a right angle is always 90 degrees.
Since the triangle is right angle
by using the cosine ratio to solve for BC
The value of cos45° = 1/√2 ,
So,
cos45° = BC / AC = BC / n

[tex]y=5[/tex], [tex]x=10[/tex]
Step-by-step explanation:
If the lines m and n are parallel then the large triangle and the small triangle are similar triangles, because they have equal angles.
By definition for similar triangles it is satisfied that if they have sides of length a, b, c and a ', b' and c 'then:
[tex]\frac{a}{a'}=\frac{b}{b'} =\frac{c}{c'}[/tex]
In this case
[tex]a = 12\\a' = 4\\c = 15\\c' = y[/tex]
So:
[tex]\frac{12}{4}=\frac{15}{y}[/tex]
[tex]3=\frac{15}{y}[/tex]
[tex]y=\frac{15}{3}[/tex]
[tex]y=5[/tex]
Therefore
if [tex]x+y=15[/tex] and [tex]y=5[/tex] then [tex]x =10[/tex]

What is the center of the circle that has a diameter whose endpoints are(5, -6) and (-1, -8)?
Answer:
(2, -7).
Step-by-step explanation:
The center is the midpoint of the diameter.
This is (5 + -1) / 2 , (-6+(-8)/2)
= (4/2, -14/2)
= (2, -7).
Answer: The center is (2,-7)
Step-by-step explanation:
In this case the center of this circle is the midpoint of its diameter. Then you need to use this formula:
[tex]Midpoint=Center=(\frac{x_1+x_2}{2},\frac{y_1+y_2}{2})[/tex]
Knowing that this circle has a diameter whose endpoints are (5, -6) and (-1, -8), you can identify that:
[tex]x_1=5\\x_2=-1\\y_1=-6\\y_2=-8[/tex]
Then you can substitute these coordinates into [tex]Center=(\frac{x_1+x_2}{2},\frac{y_1+y_2}{2})[/tex], getting:
[tex]Center=(\frac{5+(-1)}{2},\frac{-6+(-8)}{2})[/tex]
[tex]Center=(\frac{5-1}{2},\frac{-6-8}{2})[/tex]
[tex]Center=(2,-7)[/tex]

Cindy sold her camera for $300, thus making a profit
of $60. What was her percent of profit?
A) 10%
B) 15%
C) 20%
D) 25%
Answer:
c. 20%
Step-by-step explanation:
60 is 20% of 300
The answer to the question is 25%
The percent of profit can be calculated by using the formula:
Profit Percentage = (Profit / Cost Price) x 100%
Given that Cindy made a profit of $60 by selling her camera for $300, her profit percentage would be:
Profit Percentage = (60 / 240) x 100% = 25%

Answer:
[tex]330,\frac{5\pi }{3},\frac{7\pi }{6}, \frac{2\pi }{3} ,\frac{\pi }{2}[/tex]
Step-by-step explanation:
We have to find the alternate angles regarding π
So,
[tex]\frac{\pi }{2} = 90 \\330\\\frac{5\pi }{3} = 300\\\frac{7\pi }{6} = 210\\\frac{2\pi }{3} = 120[/tex]
As we have all the angles in number form, we can sort them in descending order to get the answer
330, 300, 210, 120, 90
Writing using pi form
[tex]330,\frac{5\pi }{3},\frac{7\pi }{6}, \frac{2\pi }{3} ,\frac{\pi }{2}[/tex]
Hence, Option D is correct ..
Answer:
D) 330, [tex]\frac{5\pi }{3}[/tex], [tex]\frac{7\pi }{6}[/tex], [tex]\frac{2\pi }{3}[/tex], [tex]\frac{\pi }{2}[/tex]
Step-by-step explanation:
To find the order from greatest to least, we need to convert all [tex]\pi[/tex] terms to degrees.
We know that π = 180°
[tex]\frac{\pi }{2} = \frac{180}{2} = 90[/tex]
[tex]\frac{5\pi }{3} = \frac{5*180}{3} = \frac{900}{3} = 300[/tex]
[tex]\frac{7\pi }{6} = \frac{7*180}{6} = \frac{1260}{6} = 210[/tex]
[tex]\frac{2\pi }{3} = \frac{2*180}{3} = \frac{360}{3} = 120[/tex]
Now we have converted all in degrees. Let's arrange them from greatest to least.
330, 300, 210, 120, 90
Let's write them using [tex]\pi[/tex] term.
330, [tex]\frac{5\pi }{3}[/tex], [tex]\frac{7\pi }{6}[/tex], [tex]\frac{2\pi }{3}[/tex], [tex]\frac{\pi }{2}[/tex]
Therefore, the answer is D) 330, [tex]\frac{5\pi }{3}[/tex], [tex]\frac{7\pi }{6}[/tex], [tex]\frac{2\pi }{3}[/tex], [tex]\frac{\pi }{2}[/tex]
Evaluate: log1255

b.1/2
c. 2/3
Answer:
[tex]\frac{1}{3}[/tex]
Step-by-step explanation:
Using the rule of logarithms
[tex]log_{b}[/tex] x = n ⇔ x = [tex]b^{n}[/tex]
let [tex]log_{125}[/tex] 5 = n, then
5 = [tex]125^{n}[/tex]
note that 125 = 5³ ⇒ [tex](5^3) ^{n}[/tex] = [tex]5^{3n}[/tex]
Since bases are equal ( both 5) equate the exponents
3n = 1 ( divide both sides by 3 )
n = [tex]\frac{1}{3}[/tex]
The value of the expression log₁₂₅5 is 1/3.
The correct option is A.
What is Logarithmic?The inverse of exponentiation is the logarithm. This indicates that the exponent to which b must be raised in order to obtain a number x is the logarithm of x to the base b.
Given:
A logarithmic expression,
let log₁₂₅5 = x
Then simplifying,

Answer:
x = 7
Step-by-step explanation:
recognize that this is a right triangle with one of the internal angles = 45°. This means that the other angle not shown is 180 - 90 - 45 = 45°
This makes the triangle an isosceles triangle.
If so, x must be the same length as the other side adjacent to 90°

There are 5 stacks of huge waffles that each weigh 45 pounds, and a group of people want to eat all of the stacks of waffles. If a person can eat 2 pounds, how many people are necessary to eat all of the waffles?+
Answer:
113
Step-by-step explanation:
Total mass of waffles = 45 x 5 = 225 pounds
No. of people needed = 225 / 2 + 1 = 112 + 1 = 113
You need to add 1 because 112 people can only eat 224 pounds, so the last person eats only 1 pound
Answer:
113 people are necessary to eat all of the waffles.
Step-by-step explanation:
There are 5 stacks of huge waffles that each weigh 45 pounds.
Hence, Total amount of waffles=5×45 pounds
=225 pounds
A person can eat 2 pounds.
and 225/2=112.5
112 people can only eat 224 pounds, so the last person eats only 1 pound.
⇒ 113 people are necessary to eat all of the waffles.
