Answer:
Hello There. The correct answer to this is B. Because it shows that A = 4pr2 We need divide each term of 4pr2 = A r2 A-4p Then we need to do is Take the square root of both sides of the equation to eliminate the exponent on the left side. r = + A-4p Then completed of the solution is the result of both the positive and negative portions of the solution.
Hope It Helps! Good Luck.

select a setting so that each point will lie within the viewing window, (-11,5),(0,-4),(0,-7)
Answer:
Each given point will lie within the viewing window, [tex]Xmin=-12[/tex], [tex]Xmax=1[/tex], [tex]Xscl=1[/tex], [tex]Ymin=-8[/tex], [tex]Ymax=6[/tex], [tex]Yscl=1[/tex].
Step-by-step explanation:
The given points are (-11,5),(0,-4),(0,-7).
Here, the minimum values of x is -11 and maximum value of x is 0.
It means [tex]Xmin[/tex] must be less than -11 and [tex]Xmax[/tex] must be greater than 0.
The minimum values of y is -7 and maximum value of y is 5.
It means [tex]Ymin[/tex] must be less than -7 and [tex]Ymax[/tex] must be greater than 5.
Therefore, each given point will lie within the viewing window
[tex]Xmin=-12[/tex]
[tex]Xmax=1[/tex]
[tex]Xscl=1[/tex]
[tex]Ymin=-8[/tex]
[tex]Ymax=6[/tex]
[tex]Yscl=1[/tex]

the task: Set up and solve an equation to find the value of .
my answer :X = 360 -( 123 + 90)
X = 147
Answer:
360 = x+123+ 90
x = 147
Step-by-step explanation:
The three angles form a circle which is 360 degrees
360 = x+123+ 90
Subtract 123 and 90 from each side
360 -123 - 90 = x
147 = x

What is the area of the parallelogram shown below
Answer:
16
Step-by-step explanation:
The area of a parallelogram is b * h, where b and h are the base and height respectively. We know the base but not the height. However, we see a right triangle that has the height and 3 as legs and 5 as the hypotenuse. Pythagorean Triples tell us that the height is 4 and the area will be 4 * 4 = 16 sq. units. Hope this helps!
Answer: 16

What type of triangle, if any, can be formed with angle measures of 32, 126, and 32
-only an acute isosceles triangle
-either an acute isosceles triangle or an obtuse isosceles triangle
-no triangle
-only an obtuse isosceles triangle
Answer:
No triangle
Step-by-step explanation:
All triangles must have angles that measure up to 180 degrees. When you add 32, 32, and 126 you get 190. That means that no triangle can be formed.

Explain, with a test, why the two triangles in each figure are similar. Find the
unknown lengths.
Answer:
x = 3, y = 6
Step-by-step explanation:
In the figure attached,
If ΔADE and ΔABC are similar triangles, their corresponding sides will be in the same ratio.
By this property,
[tex]\frac{AB}{AD}=\frac{AC}{AE}=\frac{BC}{DE}[/tex]
[tex]\frac{AB}{AD}=\frac{AC}{AE}[/tex]
[tex]\frac{AD+BD}{AD}=\frac{AE+EC}{AE}[/tex]
[tex]\frac{3}{2}=\frac{x+1.5}{x}[/tex]
3x = 2x + 3
3x - 2x = 3
x = 3
Similarly, [tex]\frac{AB}{AD}=\frac{BC}{DE}[/tex]
[tex]\frac{3}{2}=\frac{y}{4}[/tex]
y = [tex]\frac{3\times 4}{2}[/tex]
y = 6
2. The lengths of two insects are given below.
Ladybug: 10 millimeters
Walking stick: 30 centimeters
What is the difference in length of these two insects in millimeters
A 70 mm
B 20 mm
C 290 mm
D 2,990 mm
The conversion rate of millimetres to centimetres is 10 = 1 (Meaning 10 millimetres will equal one centimetre).
Knowing this, we can convert the centimetres to millimetres by multiplying by 10.
30 x 10 = 300
So a walking stick is 300 millimetres long.
To find the difference, we need to subtract the larger number from the smaller one.
300 - 10 = 290
Therefore the answer is 290mm.
Hope this helps! :)

Answer: (5, 12, 13).
Step-by-step explanation:
Pythagorean triples are any three side lengths of a right triangle that are all whole numbers.
The most common triples are (3, 4, 5), (5, 12, 13), and (9, 40, 41).
You can test the options given in the Pythagorean theorem to see if they make the theorem correct.
25 + 64 = 100 is not correct.
9 + 16 = 36 is not correct.
25 + 144 = 169 is correct.
1 + 1 = 4 is not correct.
The correct choice is (5, 12, 13).
Answer:
[tex](5 \:, \: \: 12 \: , \: \: \: 13)[/tex]
Third answer is correct
Step-by-step explanation:
PYTHAGORAS theorem
[tex] {a}^{2} + {b}^{2} = {c}^{2} [/tex]
Let's take one by one.
1)(5,8,10)
[tex] {5}^{2} + {8}^{2} = {10}^{2} \\ 25 + 64 = 100 \\ 89 = 100[/tex]
No,it's not correct.
2)(3,4,6)
[tex] {3}^{2} + {4}^{2} = {6}^{2} \\ 9 + 16 = 36 \\ 25 = 36 [/tex]
No, it's not correct.
3)(5,12,13)
[tex] {5}^{2} + {12}^{2} = {13}^{2} \\ 25 + 144 = 169 \\ 169 = 169[/tex]
Yes,it's correct
4)(1,1,2)
[tex] {1}^{2} + {1}^{2} = {2}^{2} \\ 1 + 1 = 4 \\ 2 = 4 [/tex]
No, it's not correct
SO, IT'S CLEAR THAT THE CORRECT ANSWER IS THE THIRD ANSWER

A store sells a 1 1/4 pound package of turkey for $9.
What is the unit price of the turkey in the package?
Answer:
$7.20
Step-by-step explanation:
The first step is to convert 1 1/4 to decimal form. 1/4=0.25, which when added to the 1 gives a total weight of 1.25 pounds. Dividing this by the price to find the unit price, you get 9/1.25=$7.20 per pound of turkey. Hope this helps!
Unit price is the price when something is $1, so what you need to do is 9/1.25. The answer is $7.20, so that is the unit rate. I hope this helps.

what is the missing constant term in the perfect sqaure that starts with x^2 - 4x
Answer:
The expression is; x^2 – 4c + 4
Step-by-step explanation:
For the expression to be a perfect square, let us say the constant term should be assigned as ⇒ c;
This creates of following expression;
x^2 - 4x + c
In order to be a perfect square, the discriminant needs to be zero ;
( - 4 )^2 - 4 * ( 1 )c = 0 ,
16 – 4c = 0 ,
4c = 16 ,
c = 4 ,
Solution; The expression is, therefore; x^2 – 4c + 4

What are the zeros of the polynomial function F(x) = x3 - 5x2 - 6x?
Answer:
The zeros are {2, 3}
Step-by-step explanation:
Please use " ^ " to indicate exponentiation:
F(x) = x^3 - 5x^2 - 6x
Factoring out x, we get:
F(x) = x(x^2 - 5x - 6)
Factoing the quadratic, we get:
F(x) = x(x - 3)(x - 2) = 0
The zeros are {2, 3}
