Answer:The second option is correct
Step-by-step explanation:
Hehehehehehehehheheheh
Answer:
B, E
Step-by-step explanation:
A would be wrong because the second part (up 1) would give you (5,1) The origin is (0,0)
B is correct because (5,0) has a 5 as the x coordinate
C is wrong because the y coordinate is 0
D is wrong because A is on the x since the y coordinate is 0
E is correct because (5,0) has a 5 on the x and a 0 on the y
Which of the following expressions represents
the product of 3k and the sum of m and
one third of n?
Answer:
[tex]3k (m + \frac{1}{3}n)[/tex]
Step-by-step explanation:
Sum of m and one - third of n is :
[tex]= m + \frac{1}{3}n[/tex]
Product of 3k to the sum is :

Answer:
471.24 Inches
Step-by-step explanation:
V= πr²h (diameter=10, Radius = 5)V = (22/7 × 5 × 5) × 6V= 550 × 6V = 3300 ÷ 7V = 471.2389=round offV = 471.24 inchesSimplify (1+ 3) (2-3)

[tex] \sqrt{3} - 1[/tex]
Answer:
-1 + √3
Step-by-step explanation:
use the F.O.I.L method to solve this.
"firsts"
1 * 2 = 2
"outsides"
1 * -√3 = -√3
"insides"
√3 * 2 = 2√3
"lasts"
√3 * - √3 = -3
so you get:
2 - √3 + 2√3 - 3
combine like terms
-1 + √3
phone, it can expect to sell 1,000-2x phones.
The company uses the function r defined by r(x)=x⋅(1,000−2x) to model the expected revenue, in dollars, from selling cell phones at x dollars each.
Answer the 2 questions below.
a) What are the X-Intercepts and what do they mean in this situation?
b) At what price should the company sell their phones to get the maximum revenue? Explain your reasoning
Answer:
Step-by-step explanation:
The x intercepts are 0 and
1000 - 2x = 0 given condition
1000 = 2x Divide by 2
500 = x
So the two intercepts are 0,0 and 500,0
The intercepts mean that for (0,0) the phone company hasn't charged anything, yet. For 500,0 the phone company can sell a single phone -- not when they cost 500 dollars apiece.
The answer to the B part is completing the square.
r(x) = - 2x^2 + 1000x
r(x) = -2(x^2 - 500x )
1/2 ( 500) = 250
250^2 is what you put inside the bracket's to complete the square.
r(x) = - 2(x^2 - 500x + 250^2) + 2*250^2
r(x) = -2(x - 250)^2 + 2*62500
r(x) = - 2(x - 250)^2 + 125000
They should sell their phones at 250 dollars a piece. The total revenue is 125000. Your graph shows exactly the same thing.
If you write a product using each prime factor of two polynomials the greatest number of times it occurs in the polynomial, you get the ____________ for the polynomials.

Can I get some help solving the missing angle.
Answer:
the ans is 63°
Step-by-step explanation:
94°+24°+x(suppose)=180°(being a triangle)
x=63°
Answer:
its 63
Step-by-step explanation:
117 would be above 90 degreesand clearly its smaller than a 90 degree angle, meaning its 63 or 67 but 94+23=117 and (a full angle which is 180) 180-117 which gives u 63

The volume of a cylinder is 196in.3 and the height of the cylinder is 1 in. What is the radius of the cylinder?
Answer:
r ≈ 7.9 inches
Step-by-step explanation:
V(cylinder) = πr²h
196 = πr²(1)
196/π = r²
62.4 = r²
√62.4 = r
r ≈ 7.9

Solve for x in the triangle round your answer to the nearest tenth BRAINLIEST
Answer:
x = 16.4
Step-by-step explanation:
For right-angle triangles, we can use the trigonometry equations;
In this case, we need to use the sine equation in particular:
sinθ = opposite/hypotenuse
sin(66) = x/18
x = 0.91...(18)
x = 16.4438... ⇒ 16.4

I need explanations for Properties of Dilations and Similarity and Similarity Transformations.
I am in 10th-grade Geometry, Thank you so much!
Answer:
Properties of Dilation
Each angle of the figure is the same. Midpoints of the sides of the figure remain the same as the midpoint of the dilated shape. Parallel and perpendicular lines in the figure remain the same as the parallel and perpendicular lines of the dilated figure. The images remain the same.Similarity. In order for two figures to be similar, they must have congruent (equal) corresponding angle measures and proportional sides. Dilations create similar figures because multiplying by the scale factor creates proportional sides while leaving the angle measure and the shape the same.A similarity transformation is one or more rigid transformations (reflection, rotation, translation) followed by a dilation. When a figure is transformed by a similarity transformation, an image is created that is similar to the original figure. ... In general, similarity transformations preserve angles.A dilation stretches or shrinks a figure. The image created by a dilation is similar to the original figure. The scale factor of a dilation is the ratio of corresponding side lengths. In this course, the center of dilation will always be the origin.Dilations in Animation
The three basic rigid motions are translations, reflections, and rotations. In addition to being rigid motions, these are also considered transformations. Transformations change the location or orientation of an image but not the shape.Isometric transformations have the same shape AND size, similarity transformations just have the same shape. Isometric transformations have the same shape AND size, similarity transformations just have the same size. They are the same, no differences. ... A stretch is not a similarity transformation.[tex]\color{yellow}{}[/tex]
Find the center and radius of the circle whose equation is x 2 + y 2 - 6x - 2y + 4 = 0
(3,1), r = /6
(-3,-1), r = /6
(3,1) r = 6
(9,1), r = 36
Answer:
Solution given:
the equation of a circle is:
x²+y²-6x-2y+4=0
x²-2*x*3+3²+y²-2y+1²-1²+4=0
(x-3)²+(y-1)²=9+1-4
(x-3)²+(y-1)²=6
comparing above equation with
(a-h)²+(y-k)²=r²
we get
centre (h,k)=(3,1)
radius=√6

What is a perpendicular bisector notation?
Answer:
In a pyramid, line segment AD is the perpendicular bisector of triangle ABC on line segment BC. If AB = 20 feet and BD= 7 feet, find the length of side AC.
Step-by-step explanation:
Solution
It is given that AD is the perpendicular bisector on the line segment BC.
So, By Perpendicular Bisector Theorem, any point on line segment AD is at an equal distance from points B and C. It implies, AB = AC
AC = 20 feet.

32x + 26 = -11 can someone help pls Ik in summer school
Answer:
x = -37/32
Step-by-step explanation:
32x + 26 = -11
Subtract 26 from each side
32x + 26-26 = -11-26
32x = -37
Divide each side by 32
32x/32 = -37/32
x = -37/32
Answer:
x= -1 5/32 or x=-1.15625

Pam has 228 ounces of lemonade. She pours the lemonade into
8-ounce cups, filling as many as she can until all the lemonade is
gone. The last cup is not completely full. How much lemonade is
in the last cup?
Answer:
4 ounces
Step-by-step explanation:
If you divide 228 by 8, you will get 28.5. The 0.5 into a fraction would be 1/2. Half of 8 would be 4. In the end, there should be 28 full 8-ounce cups and one cup with 4 ounces.

Felipe’s solution to an equation is shown below:
Given: x^2+6x+8=0
Step 1: (x+2)(x+4)=0
Step 2: x+2=0 or x+4=0
Step 3: x= -2 or x= -4
Which property of real numbers did Felipe’s use for step 2?
A. Distributive property of multiplication over addition
B: Multiplication property of equality
C. Commutative property of multiplication
D: Zero product of multiplication
Answer:
D. Zero product of multiplication
Step-by-step explanation:
The given equation is presented as follows;
Given: x² + 6·x + 8 = 0
By factorization, to find numbers represented by variables, 'a' and 'b', such that a + b = 6 and a×b = 8, we have, a = 2, and b = 8 as a possible solution by observation
Step 1: (x + 2)·(x + 4) = 0
Given that (x + 2) × (x + 4) = 0, we have
Step 2: x + 2 = 0 or x + 4 = 0, by zero product of multiplication
The zero-product property states that the when two non zero numbers are multiplied, the result is nonzero
Therefore, when two numbers are multiplied, and have a result of zero, for example, i × j = 0, then, either, i = 0, or j = 0
By the zero-product rule, either, (x + 2) = 0, or (x + 4) = 0
Therefore, we have;
Therefore;
Step 3: x = -2 or x = -4
The property of real numbers Felipe's use for step 2 is the Zero product of multiplication.
Find the volume of a pyramid with a square base, where the side length of the
base is 8.7 cm and the height of the pyramid is 13.1 cm. Round your answer
to the nearest tenth of a cubic centimeter.
Answer: V= 330.513 cm 3
Step-by-step explanation:
Area = l x w and with a square the length and width are the same, additionally the volume of a pyramid can be found by using the formula (L)(w)(h)/3 so
8.7 x 8.7 = 75.69cm^2
75.69 x 13.1 = 991.539
991.539 ÷ 3 = 330.513 cm^3
