Answer:
vertex = (- 1, 0 )
Step-by-step explanation:
Given a parabola in standard form
f(x) = ax² + bx + c ( a ≠ 0 )
Then the x- coordinate of the vertex is
x = - [tex]\frac{b}{2a}[/tex]
f(x) = 3x² + 6x + 3 ← is in standard form
with a = 3, b = 6 , then
[tex]x_{vertex}[/tex] = - [tex]\frac{6}{6}[/tex] = - 1
Substitute x = - 1 into f(x) for corresponding y- coordinate of vertex
f(- 1) = 3(- 1)² + 6(- 1) + 3 = 3(1) - 6 + 3 = 3 - 6 + 3 = 0
vertex = (- 1, 0 )

Find the perimeter of a rectangle whose length is 12 longer than its width
with an area of 45 square feet. To earn 5 points write the mathematical
sentence, the value of Length, width and perimeter
Answer:
l = 21
w = 9
P = 60
Step-by-step explanation:
l = 12 + w
A = l*w = 45
substitute l = 12 +w
45 = (12 + w) * w
45 = 12w + w^2
w^2 + 12w - 45 = 0
w^2 + 2*6*w +36 = 45 + 36 (added 36 on both sides 6^2)
(w + 6) ^2 = 45+36 = 81
w + 6 = +-9
As width cannot be negative w = 9
so l = 12 + 9
= 21
Perimeter = P = 2 (l + b)
= 2 ( 21 + 9)
= 2 (30)
= 60

A rocket is launched from a tower. The height of the rocket, y in feet, is related to the
time after launch, x in seconds, by the given equation. Using this equation, find the
time that the rocket will hit the ground, to the nearest 100th of second.
y = –16x2 + 119x + 57
Answer:
7.89 seconds
Step-by-step explanation:
using the quadratic formula (-b+-√(b^2-4ac))/2a
a=-16 b=119 c=57
x=-0.451
and
x=7.889
time cant be negative so use the positive x
Time required for the rocket to hit the ground would be 7.9 s.
What is a quadratic equation?A quadratic equation is the second-order degree algebraic expression in a variable. the standard form of this expression is ax² + bx + c = 0 where a. b are coefficients and x is the variable and c is a constant.
We are given the quadratic equation as;
-16x² + 119x + 57 = 0
By using the quadratic formula,
x = [-b ± √b² - 4ac]/2a
Here, a = -16, b = 119 and c = 57
b² - 4ac = (119 )² - 4(-16)(57)
= 14161 + 3648
= 17809
So, x = [-(119) ± √17809]/ 16(2)
= (-119 ± 133.4)/32
Therefore, the time is 7.9 s.

Can square pieces of foam board, each with an area of 169 square inches, be cut and used to construct a cube with a volume of 1,728 cubic
inches?
Option C is correct, No the side length of board is less than the side of the cube.
What is Three dimensional shape?a three dimensional shape can be defined as a solid figure or an object or shape that has three dimensions—length, width, and height.
The volume of the cube is 1,728 cubic inches:
169n³= 1,728
n³ = 10.237
n = 2.28
The surface area of the cube does not exceed the total area of the foam board:
6n² ≤ 169
n² ≤ 28.17
n = 5.31
It is not possible to use square pieces of foam board with an area of 169 square inches to construct a cube with a volume of 1,728 cubic inches.
Therefore, square pieces of foam board with an area of 169 square inches cannot be cut and used to construct a cube with a volume of 1,728 cubic inches.

Brainliest to who shows ALL work! :D
Answer:
n = 8
Step-by-step explanation:
13 - 3/4n = 3/4n + 1
add 3/4n to both sides
13 = 3/2n + 1
subtract 1 from both sides
12 = 3/2n
divide both sides by 3/2
n = 8

the sum of three whole numbers in a row is 57. what are the three numbers?
Answer:
18, 19, 20
Step-by-step explanation:
(n) + (n + 1) + (n + 2) = 57
3n + 3 = 57
3n = 57 - 3 = 54
n = 54/3 = 18
three numbers are 18, 18+1, 18+2
18, 19, 20
Answer:
18,19,20
Step-by-step explanation:
x + (x+1) + (x+2) = 57
x + x + 1 + x + 2 = 57
Combine like terms
3x + 3 = 57
subtract 3 from both sides
3x = 54
divide both sides by 3
x = 18
The answer is 18, 19, 20
Since we know the value of x, we can look at it like this:
x + (x+1) + (x+2) --- > 18 + (18+ 1) + (18+2) --> 18 + 19 + 20

line w passes through point (-6,-7) and has a slope 1/2. what is the equation for the line in point-slope form?
Answer:
y + 7 = [tex]\frac{1}{2}[/tex] (x + 6)
Step-by-step explanation:
The equation of a line in point- slope form is
y - b = m(x - a)
where m is the slope and (a, b ) a point on the line
Here m = [tex]\frac{1}{2}[/tex] and (a, b ) = (- 6, - 7 ) , then
y - (- 7) = [tex]\frac{1}{2}[/tex] (x - (- 6) ) , that is
y + 7 = [tex]\frac{1}{2}[/tex] (x + 6)
