Answer:
Step-by-step explanation:
Quadratic equation has been given as,
[tex]y=-x^{2} +6x+4[/tex]
Converting this equation into vertex form,
[tex]y=-(x^{2}-6x)+4[/tex]
[tex]y=-[x^{2}-2(3x)+9-9]+4[/tex]
[tex]y=-[x^{2}-2(3x)+3^2]+4+3^2[/tex]
[tex]y=-(x-3)^2+4+9[/tex]
[tex]y=-(x-3)^2+13[/tex]
By comparing this equation with the vertex form of a quadratic equation,
y = (x - h)² + k
Here, (h, k) is the vertex of the parabola.
Vertex of the parabola → x = 3, y = 13
Axis of symmetry → x = 3

Answers
Answer:
Option A
Step-by-step explanation:
The complete question is
The pentagon ABCDE is graphed on a coordinate plane with vertices A(0, 0), B(3, 5), C(3, 8), D(8, 5), and E(8, 0). What is the pentagon's perimeter?
Solution -
We will find the length of all the sides of pentagon and then add them
Length of AB = Sqrt ((3-0)^2+(5-0)^2) = Square root of 9+25 = 5.83
Length of BC = Sqrt ((3-3)^2+(8-5)^2) = Square root of 9 = 3
Length of CD = Sqrt ((8-3)^2+(5-8)^2) = Square root of 5^2+-3^2
= 5.83
Length of DE = Sqrt ((8-8)^2+(0-5)^2) = Square root of 25 = 5
Length of EA = Sqrt ((8-0)^2+(0-0)^2) = Square root of 64= 8
Perimeter=8+5+5.83+5.83+3= 27.66 units =27.66 units
Option A

enough lemons to make three 9-inch lemon pies, each requiring half a cup of lemon juice?
Answers
Answer: It costs about 7.32 to buy enough lemons.
Step-by-step explanation:
Each lemon yields 2 tablespoons, which is equal to one fluid ounce.
8 fluid ounces = one cup, 4 fluid ounces = half a cup
Four lemons will provide juice for one pie.
Cost of one pie = 4 0.61 = 2.44
Cost of three pies = 2.44 3 = 7.32

Answers
9514 1404 393
Answer:
39.375 : 65.625
Step-by-step explanation:
The meaning of "reduce" in this context is unclear. We assume you want to divide the quantity 105 into parts that have a ratio of 3 : 5. Then the smaller part will be 3/(3+5) = 3/8 of the total; the larger part will be 5/8 of the total.
3/8 × 105 = 39 3/8
5/8 × 105 = 65 5/8
The divided quantities are ...
39.375 : 65.625
find the perimeter of the figure below.
PLEASE GIVE A EXPLANATION
Answers
Answer:
Perimeter of the figure = 198.54 feet
Step-by-step explanation:
Given figure comprises a rectangle and two semicircles.
Perimeters of two semicircle = 2πr
Here 'r' = Radius of the circle
Perimeter of two semicircles at the sides of the rectangle = [tex]2\pi (\frac{25}{2})[/tex]
= 25π feet
= 78.54 feet
Length of side AB = Length of side CD = 60 feet
Perimeter of the given figure = 2(60) + 78.54
= 198.54 feet

The bakery shop purchased 7 2/10 pounds of sugar and 7 5/10 pounds of flour. How much sugar and flour did they purchase in all?
Answers
Answer:
Sugar = 1-2/5 pounds, Flour = 3-1/2 pounds
Together = 5-9/10 pounds
Step-by-step explanation:
sugar = 7(2/10)
flour = 7(5/10)
sugar + flour = 7(2/10) + 7(5/10)
sugar = 14/10 or 1-2/5 pounds
flour = 35/10 or 3-1/2 pounds
