Find the vertex of the function given below.
y= 2x2 + 4x + 1
Answer:
vertex is (-1,-1)
Step-by-step explanation:
2 ways
1. get into vertex form y=a(x-h)^2+k
2. use math hacks
1.
vertex is (h,k) in y=a(x-h)^2+k
complete square
y=(2x^2+4x)+1
y=2(x^2+2x)+1
y=2(x^2+2x+1-1)+1
y=2((x+1)^2-1)+1
y=2(x+1)^2-2+1
y=2(x+1)^2-1
y=2(x-(-1))^2+(-1)
vertex is (-1,-1)
2.hack way
in form y=ax^2+bx+c
x value of vvertex is -b/2a
given
y=2x^2+4x+1
b=4, a=2
xvaluevertex=-4/(2*2)
xvaluevertex=-4/4=-1
sub back to find y value
y=2(-1)^2+4(-1)+1
y=2(1)-4+1
y=2-4+1
y=-1
y value is -1
Answer:
(-1,-1)
Step-by-step explanation:
To find the x coordinate, we use the formular x = -b/2a where b=4 and a = 2 from the given function.
hence x = -(4)/2(2) = -1
then to get the y coordinate we substitute the value of x into the given function, so y = 2(-1)^2+4(-1)+1 = -1
therefore, the vertex is (-1,-1)

The required base of the isosceles triangle is given as 38 feet.
What is the isosceles triangle?A triangle with two sides and two congruent angles is called an isosceles triangle.
here,
For a given isosceles triangle,
side/base = 2 / 7
side = 2/7 base = 7 /2 sides
According to the question,
The perimeter of the triangle is 304 feet,
2 side + base = 304
2 [7/2 base] + base = 304
8 base = 304
base= 304 / 8
base = 38 feet
Thus, the required base of the isosceles triangle is given as 38 feet.

24 x 2 = 52 can only be in base 6
because 2¹ 4 2 x 4 = 8/6 = 1 rem 2.

From the above , we can see theta 24 x 2 = 52 can only be in base 6.
Because only 2 x 4 = 12 can be possible in base 6.

Suppose you go shopping for a new futon bed for your room. The model you really like happens to be on sale for $1125. It's original price is $1200. What percent of the original price will you save if you purchase it?
Answer:
9.375% rounded 9%
Step-by-step explanation:
so if the original price is 1200 that is equal to 100% so if 1200=100% then to get ten percent of 1200 u would divide 1200 by 10 which gets you 120 and if the sale price is 1125 then u do 1125 divide by 120 because that is 10% so that gives you 9.357 and you add you percentage on and there is your anwser hope this helped ;)

1. m<C = 48°.
2. <X = <Y.
Explanation :<ABD = <CDB = 62°
<BDA = <DBC = 70°
<DBC + <BCD + <CDB = 180°
70° + <BCD + 62° = 180°
132° + <BCD = 180°
<BCD = 180° - 132°
<BCD = 48°
m<C = 48°

The sum of two numbers is –11. The difference of the two numbers is –7. What is the product of the two numbers?
Answer:
18
Step-by-step explanation:
According to the numbers the both numbers have to be negative
subtracting a negative will be the same as addition and so thats why the difference is bigger.
now its time for guess and check.

-11
but -6-(-5)=-1
so lets try
-9+(-2)=-11
-9-(-2)=-7

Describe, in words, how the figure at the right was translated.
Answer:
8 up, 6 left
Step-by-step explanation:
Locate any point from triangle A and go up 8 steps to get on the same level as triangle A'. Then, move to the left 6 steps.
The graph translated 6 unit left and 8 unit upward.
What are coordinates?A pair of numbers called coordinates are used to locate a point or a form in a two-dimensional plane. The x-coordinate and the y-coordinate are two numbers that define a point's location on a 2D plane.
Given, A figure "A" that translated at different position in cartesian plane.
Since, A translation is when a geometric figure slides up, down, left or right on the coordinate plane. The figure moves its location, but doesn't change its orientation. It also doesn't change its size or shape.
Thus, we can observe only one point on the figure and calculate the movement of the figure.
Lets focus on the left bottom corner of the figure.
It moves from the coordinates (1, -5) to the coordinates ( -5, 3)
Since Horizontally translating a graph is equivalent to shifting the base graph left or right in the direction of the x-axis
So, we can say it translated to the lefty by 6 unit.
Same it goes with vertical translation.
Therefore, The graph translated 6 unit left and 8 unit upward.
