Answer:
True.
Step-by-step explanation:
It is because it is in the form [tex]a^2x^2+2abx+b^2[/tex] and this equals [tex](ax+b)^2[/tex].
Why it is in that form: well comparing [tex]a^2x^2+2abx+b^2[/tex], we have [tex]a=1, b=1[/tex]. Testing, plug in those values:
[tex](1)^2x^2+2(1)(1)x+(1)^2[/tex]
[tex]1x^2+2x+1[/tex]
[tex]x^2+2x+1[/tex].
This has the squared form of [tex](x+1)^2[/tex].

ZE is the angle bisector of measure YEX and the perpendicular bisector of GF, GX is the angle bisector of measure YGZ and the perpendicular bisector of EF, FY is the angle bisector of measure ZFX and the perpendicular bisector of EG. Point A is the intersection of EZ, GX, and FY.
Answer:
C
Step-by-step explanation:
The center of inscribed circle into triangle is point of intersection of all interior angles of triangle.
The center of circumscribed circle over triabgle is point of intersection of perpendicular bisectors to the sides.
Circumscribed circle always passes through the vertices of the triangle.
Inscribed circle is always tangent to the triangle's sides.
In your case angles' bisectors and perpendicular bisectors intesect at one point, so point A is the center of inscribed circle and the center of corcumsribed circle. Thus, these circles pass through the points X, Y, Z and G, E, F, respectively.
A hardware store buys 300 feet of nylon rope. The store sells the rope by the inch. A customer can purchase 40 inches of the rope for $1.60. The store sells all of the rope and makes a profit of $54. How much did the store pay for the rope in dollars per inch.
Pls answer this question it’s important..
Answer:
0.025 $/in.
Step-by-step explanation:
The store bought 300 ft of rope.
1 ft = 12 in.
300 ft * 12 in./ft = 3600 in.
The store bought 3600 inches of rope.
The store sells 40 inches of rope for $1.60. We can find the selling unit price of rope in dollars per inch.
($1.60)/(40 in.) = $0.04/in.
The store sells the rope at a price of $0.04 per inch.
The store sold all the rope at $0.04/in.
3600 in. * $0.04/in. = $144
The store sold all the rope for $144.
The profit was $54 for selling ll the rope.
$144 - $54 = $90
The bought the rope for $90.
The cost is dollars per inch is
($90)/(3600 in.) = 0.025 $/in.

If 12% of the number is 24, what is the number?
Good luck!
Answer:
200
Step-by-step explanation:
12% is the same thing of .12
x = the number you are trying to find
.12(x) = 24 ----- This means that 12% of x is 24.
x = 24/.12
x = 200
To solve this you must use a proportion like so...
[tex]\frac{part}{whole} = \frac{part}{whole}[/tex]
12 is a percent and percent's are always taken out of the 100. This means that one proportion will have 12 as the part and 100 as the whole
We want to know out of what number is 24 12% of. This means 24 is the part and the unknown (let's make this x) is the whole.
Here is your proportion:
[tex]\frac{24}{x} =\frac{12}{100}[/tex]
Now you must cross multiply
24*100 = 12*x
2400 = 12x
To isolate x divide 12 to both sides
2400/12 = 12x/12
200 = x
This means that 12% of 200 is 24

Alvin throws the football to a receiver who jumps up to catch the ball. The height of the ball over time can be represented by the quadratic equation -4.9t2 + 7.5t + 1.8 = 2.1 . This equation is based on the acceleration of gravity -4.9 m/s2, the velocity of his pass is 7.5 m/s and releases the football at a height of 1.8 meters, and the height where the receiver catches the ball of 2.1 meters. Put the equation in standard form and then solve by using the quadratic equation.
Answer:
The standard form of the equation is 49t² - 75t + 3 = 0
The solution of the equations are 1.49 and 0.041
Step-by-step explanation:
* Lets explain how to solve the problem
- The standard form of the quadratic equation is ax² + bx + c = 0,
where a , b , c are constant and a can not be 0
∵ The quadratic equation is -4.9t² + 7.5t + 1.8 = 2.1
- Lets make the left hand side equal to 0
∵ -4.9t² + 7.5t + 1.8 = 2.1 ⇒ subtract 2.1 from both sides
∴ -4.9t² + 7.5t - 0.3 = 0 ⇒ multiply each term by -10
∴ 49t² - 75t + 3 = 0
* The standard form of the equation is 49t² - 75t + 3 = 0
∵ ax² + bx + c = 0
∴ a = 49 , b = -75 , c = 3
- Lets use the formula [tex]x=\frac{-b+-\sqrt{b^{2}-4ac}}{2a}[/tex] to solve
the equation
∴ [tex]x=\frac{-(-75)+\sqrt{(-75)^{2}-4(49)(3)}}{2(49)}=1.49[/tex]
∴ [tex]x=\frac{-(-75)-\sqrt{(-75)^{2}-4(49)(3)}}{2(49)}=0.041[/tex]
* The solution of the equations are 1.49 and 0.041

Koalas absorb only 25% of the fiber they eat. A koala absorbed 10.5 ounces of fiber in one day. How many ounces of fiber did he eat that day?
42 ounces
Step-by-step explanation:In this question, it is asking how many ounces of fiber did the Koala eat that day.
In order to solve this question, we would need to gather some important information from the question.
Important Information:
Koalas absorb only 25% of fiber they eatKoala absorbed 10.5 ounces of fiber in 1 dayWith the information above, we can solve the question.
We know that koalas only absorb 25% of fiber. We also know that a koala absorbed 10.5 ounces of fiber.
This means that the 10.5 ounces is 25% of fiber. This is 1/4 of the fiber it ate.
Now, we just need to find the other 3/4.
We could just multiply 10.5 by 4 to find how much fiber it ate that day.
[tex]10.5*4=42[/tex]
When you multiply, you should get 42.
This means that the Koala ate 42 ounces of fiber that day.
I hope this helps you out.Good luck on your academics.Have a fantastic day!Answer:
42
Step-by-step explanation:
We seek the answer to the question "10.5 ounces is 25% of what number?" If we call the unknown number of ounces x, we have the equation 10.5=0.25x. Dividing both sides by 0.25, we have x=10.5/0.25=42 ounces of fiber.
If x= 6 is the only x-intercept of the graph of a quadratic equation, which statement best describes the discriminant of the
equation?
Answer:
discriminant is zero (0)
Step-by-step explanation:
Actually, you have a double root here: {6, 6}: "two real, equal roots." That tells us immediately that the value of the discriminant was zero (0).
Answer:
The discriminant of the equation is zero.
Step-by-step explanation:
The given graph is a quadratic equation. If x = 6 is the only x-intercept of the graph, then the roots must be equal.
The quadratic equation will have two solutions. Here the two solutions are equal x = 6.
If the roots are equal, then the discriminant is zero.
The factors of the quadratic equation (x - 6) (x - 6)
= [tex]x^2 - 6x - 6x + 36[/tex]
= [tex]x^2 -12x + 36[/tex]
Discriminant = [tex]b^2 - 4ac[/tex]
Here a = 1, b = -12 and c = 36
Discriminant = [tex](-12)^{2} - 4.1.36[/tex]
= 144 - 144
= 0
Therefore, the answer is "The discriminant of the equation is zero."

What is the length of BC in the right triangle 9 and 12 below
The length of BC in the right triangle with sides 9 and 12 is 15.
Explanation:In a right triangle, the length of the hypotenuse can be found using the Pythagorean theorem, which states that the square of the hypotenuse is equal to the sum of the squares of the other two sides.
In this case, the lengths of the other two sides are given as 9 and 12. Let's label the hypotenuse as BC. We can use the Pythagorean theorem to solve for BC:
a2 + b2 = c2
92 + 122 = c2
81 + 144 = c2
225 = c2
Taking the square root of both sides, we find that the length of BC is 15 units.
The u-drive rent-a-truck company plans to spend $8 million on 280 new vehicles. Each commercial van will cost $25,000 , each small truck $30,000 , and large truck $40,000. Past experience shows that they need twice as many vans as small truck. How many of each type of vehicle can they buy?
Answer:
1 large truck, 99 small trucks and 180 commercial vans
Step-by-step explanation:
Step 1 : Write the data.
Total amount: 8,000,000
Total trucks needed: 280
Cost of commercial van (x) = $25,000
Cost of small truck (y) = $30,000
Large truck = $40,000 (from my understanding, only 1 large truck has to be bought since the amount given for commercial vans and small trucks is for each of it.
Since they need twice as many vans as small trucks, commercial van will be 2y and small truck will be y
Step 2 : Form two equations
40,000 + 25000(x) + 30000(y) = 8,000,000
25000(x) + 30000(y) = 7960,000 (equation 1)
1(large truck) + x + y =280
x + y = 279 (equation 2)
Step 3 : Find the value of y
From equation 2:
x = 279 - y
From equation 1:
25000(x) + 30000(y) = 7960,000
25000(279 - y) + 30000(y) = 7960,000
-25000y + 30000y + 6975000 = 7960000
5000y = 985000
y= 98.5 rounded off to 99 small trucks
Step 4: Find value of x
x + y = 279
y = 279 - 99
y = 180 commercial vans
Step 5: Answer how many type of each vehicle can they buy.
They can buy:
1 large truck
99 small trucks
180 commercial vans

A (5, 3), B (2, 1), and C (-2, 4) are the coordinates of a triangle's vertices. If the triangle is reflected over the x-axis, what are the coordinates of the image?
Answer:
A(5,3) ->A'(5,-3)
B(2,1) ->B'(2,-1)
C(-2,4) ->C'(-2,-4)
Step-by-step explanation:
If a point is reflected over the x-axis, it ends up on the opposite side of the x-axis with the same distance from the x-axis.
So what that means is the x-coordinate will stay the same and the y-coordinate will be opposite of what it was.
So if we reflect each of your points through the x-axis you will get:
A(5,3) ->A'(5,-3)
B(2,1) ->B'(2,-1)
C(-2,4) ->C'(-2,-4)
Answer:
(5,-3) (2,-1) (-2,-4)
Step-by-step explanation:
When reflection over the x-axis the rule is (x,y) becomes (x, -y)
so your x will stay the same but your y will change
if A and B are mutually exclusive events with P(A)= 0.3 and P(B)= 0.5, then P(A and B)=
If A and B are mutually exclusive events with P(A) = 0.3 and P(B) = 0.5, then P(A and B) = 0.
Explanation:If A and B are mutually exclusive events with P(A) = 0.3 and P(B) = 0.5, then P(A and B) = 0.
Mutually exclusive events are events that cannot occur at the same time. This means that if event A happens, event B cannot happen, and vice versa. Therefore, the probability of both A and B occurring together is zero.

The system of inequalities to determine the dimensions and budget of the boxcar, according to the given restrictions in the problem, are: x + 3 >= length, x >= y + 2, and 0.50*x*(x+3) + 4 * 2.25 * y <= 50.
Explanation:The subject of this question is Mathematics, specifically the topic of inequalities. From the problem, we can create a system of inequalities based on the restrictions specified. We are told that the length of the car must be 3 inches greater than its width, which is represented by x, so one inequality is x+3 >= length. Second, the width of the car must be at least 2 inches greater than the radii of the wheels, represented by y, so we have another inequality, x >= y + 2.
Lastly, we need to account for the monetary constraint. The cost of the base is $0.50 per square inch, so the cost is 0.50*x*(x+3), and the cost of each of the 4 wheels is $2.25 per inch of radius, so the total cost is 4 * 2.25 * y. The total spending must not exceed $50, so our final inequality is 0.50*x*(x+3) + 4 * 2.25 * y <= 50. Therefore, the system of inequalities that can be used to determine the length, width of the car and the radii of the wheels is:
x + 3 >= length
x >= y + 2
0.50*x*(x+3) + 4 * 2.25 * y <= 50

Tyreese is using algebra tiles to solve the equation below.
2x + 5 = -x + (1)
answers
A. remove one x-tile from both sides. B. remove two x-tiles from the left side. C. add one positive x-tile to both sides. D. add two positive x-tiles to both sides.
for this case we have the following equation:
[tex]2x + 5 = -x + 1[/tex]
To resolve:
We add x to both sides of the equation:
[tex]2x + x + 5 = -x + 1 + x[/tex]
[tex]3x + 5 = 1[/tex]
We subtract 5 on both sides of the equation:
[tex]3x + 5-5 = 1-5\\3x = -4[/tex]
We divide between 3 on both sides of the equation:
[tex]x = - \frac {4} {3}[/tex]
Answer:
We add x to both sides of the equation
Answer:
The correct option is C) add one positive x-tile to both sides.
Step-by-step explanation:
Consider the provided equation.
2x + 5 = -x + 1
Now to solve the above equation first isolate the variables.
To isolate the variables add x to the both the side of the equation.
2x + 5 + x = -x + 1 + x
Now add the like terms.
3x + 5 = 1
Here we add the x tiles to the both the side of the equation.
Now consider the options.
The correct option is C) add one positive x-tile to both sides.

Answer:
The area of the prism: 404 square feet.
Step-by-step explanation:
The idea in this exercise is to find the areas of all the geometric figures, and then add them all.
Notice that we have four consecutive rectangles, two smaller with dimension 6 ft by 8 ft and two larger with dimension 11 ft by 8 ft. Then, combined area of this four rectangles is
A_1 = 6*8 + 6*8 + 11*8+11*8 = 48+48+88+88 = 272.
For the other two rectangles, notice that their bases has the same length (11 ft). Their height can obtained using the characteristics of the prism. In this case must be 6 ft, the same length of the base of the previous smaller rectangles. The, the combined area of this rectangle is
A_2 = 6*11 +6*11 = 66 + 66 = 132.
Finally, adding those two area we get the area of the prism: 404 square feet.
