The correct option is A.
What is a quadratic function?A polynomial function with one or more variables, where the largest exponent of the variable is two, is referred to as a quadratic function. In other terms, a "polynomial function of degree 2" is a quadratic function.
We can start by completing the square of the quadratic function g(k) = -k² + 6k - 9:
g(k) = -(k² - 6k + 9 ) = -(k - 3)²
Option A can be simplified as:
g(k) = -(k - 3)²
Compared with the completed square form of g(k), we can see that option A is equivalent to g(k).
Therefore, the answer is A. g(k) = -(k - 3)²

The value of x = 15
Hence,
AB = x = 15 inBC = 2x+1 = 2(15)+1 = 30+1 = 31 inAC = x-3 = 15 - 3 = 12 inStep-by-step explanation:
We know that the perimeter of a triangle is the sum of all the sides of a triangle.
Given
Perimeter = 58 in
AB = x
BC = 2x+1
AC = x-3
so the equation becomes
Perimeter = AB + BC + AC
58 = x + 2x+1 + x-3
58 = 4x - 2
4x = 58+2
4x = 60
4x/4 = 60/4
x = 15
Thus, the value of x = 15
Hence,
AB = x = 15 inBC = 2x+1 = 2(15)+1 = 30+1 = 31 inAC = x-3 = 15 - 3 = 12 inVERIFICATION
Perimeter = AB + BC + AC
58 = 15+31+12
58 = 58
A 30-foot electric line is suspended between the tops of two 20-foot electric poles on ground level. The lowest point of the line is 5 feet above the ground. What is the distance between the two electric poles?
Answers
Answer:
The appropriate response will be "Zero (0)". A further explanation is given below.
Step-by-step explanation:
This does not make any logical sense, it seems to be 15 feet from either the peak including its poles to something like the edge of that same wire, therefore half including its 30 would be 15 feet. This always implies that perhaps there is no space seen between points, the poles must've been interacting or overlapping.The response is therefore "0".
If a = –2 – 5i and b = –i, then find the value of the ab^3 in fully simplified form.
Answers
Answer:
5 + 2i
We were given the complex numbers;
a = - 2 - 5i
and
b = - i
We want to find the product;
ab^3 ^ = Exponent
We substitute the complex numbers into the expression and simplify
( - 2 - 5i ) (i)^3 ^ = Exponent
This is rewritten as:
( - 2 - 5i) (i)^2 x i ^ = Exponent
Note that
i^2 = - 1 ^ = Exponent
We substitute to obtain:
( - 2 - 5i ) x - i
Let us expand to get:
- 2 x - i + 5i x - i
This simplifies to:
2i - 5i^2 ^ = Exponent
This gives:
2i - 5 ( - 1 ) = 2i + 5

What is an equation?Equations are mathematical expressions that have two algebras on either side of an equal (=) sign. The expressions on the left and right are shown to be equal, demonstrating this relationship. L.H.S. = R.H.S. (left-hand side = right side) is a fundamental simple equation.
From the given values in the question we have;
a = -2 + 2i
b = -5i
Thus
ab³ = (-2 + 2i) × (-5 i)³
= (-2 + 2i) (-125 i³)
= (-2 + 2i) (-125 (-i))
= (-2 + 2i) (+125 i)
= 125 i(-2) + 125 i(2i)
= -250 i + 250 i²
= -250 i -250 or,
ab³ = -250 (i+1)

1/2 ( x - 4 ) = 1/3 ( x + 2)
pls help me
Answers
Answer:
x=16
Step-by-step explanation:
1/2 ( x - 4 ) = 1/3 ( x + 2)
distribute both sides
1 /2 (x−4)= 1/ 3 (x+2)
( 1 /2 )(x) + ( 1/ 2 )(−4) =( 1 /3 ) (x)+( 1/3 )(2)(Distribute)
1 /2 x+−2= 1 /3 x+ 2 /3
1 /2 x+−2= 1 /3 x+ 2 /3
Step 2: Subtract 1/3x from both sides.
1/2x -2 -1/3 x
x= 1 /3 x + 2/3 − 1/ 3 x
1 /6 x−2= 2/ 3
Step 3: Add 2 to both sides.
1 /6 x −2+2= 2/ 3 +2
1 /6 x = 8 /3
Step 4: Multiply both sides by 6.
6*( 1/6 x) =6*( 8 /3 )
x=16
1/2x - 2 = 1/3x + 2/3
Then, isolate x. To do this, subtract 1/2x on both sides and subtract 2/3 from both sides.
-2 - 2/3 = 1/3x - 1/2x
Make them the same denominator. The left side's denominator is 3 and the right side's denominator is 6.
-6/3 - 2/3 = 2/6x - 3/6x
Subtract.
-8/3 = -1/6x
Multiply both sides by -6 to get rid of the denominator on x.
-8/3 * -6 = -1/6x * -6
48/3 = x
16 = x
Your answer is 16.

proportional constant
Answers
Answer:
The value of the proportionality constant (y to x) is: 3/10
Step-by-step explanation:
We know the slope of any graph where 'y' varies directly with 'x' gives us the constant of proportionality 'k'.
i.e. y = kx
and k = y/x
Given the points
(100, 30)(300, 90)(500, 150)We know that the proportionality constant (y to x) is:
k = y/x
For the point (100, 30)
k = 30/100=3/10
For the point (300, 90)
k = 90/300=3/10
For the point (500, 150)
k = 150/500=3/10
As the value of proportionality constant (y to x) is the same.
i.e. k = 3/10
Thus, the value of the proportionality constant (y to x) is: 3/10

Answer:
65°
Step-by-step explanation:
Let the unknown angle be ∠ABC
∠ABC + 78° + 37° = 180° (angle sum property of a triangle)
∠ABC + 115° = 180°
∠ABC = 180° - 115°
∠ABC = 65°

The side of a cube is increasing at a rate of 2 kilometers per hour. At a certain instant, the side is 1.5. What is the rate of change of the volume of the cube at that instant (in cubic kilometers per hour)?
Answers
Answer:
dV/dt = 13,5 [Km³/h]
Step-by-step explanation:
The volume f the cube is:
V = x³ where x is a side of the cube, then tacking derivatives with respect to time on both sides of the equation
dV/dt = 3*x² dx/dt
dx/dt = 2 km/h
at the time when the side x = 1,5 Km
dV/dt = 3* (1,5)²*2 [km³/h]
dV/dt = 13,5 [Km³/h]
