Answer:
minium:-2................
The function f(x) = 4x² – 16x + 6 has a minimum value is –10 when the value of x is 2. Then the correct option is B.
What is differentiation?
The rate of change of a function with respect to the variable is called differentiation. It can be increasing or decreasing.
The function is given below.
[tex]f(x) = 4x^2 -16x + 6[/tex]
Differentiate the function, then we have
[tex]\dfrac{d }{dx} f(x) =\dfrac{d}{dx}(4x^2 -16x + 6) \\\\ \dfrac{d }{dx} f(x) =8x - 16 \\[/tex]
The value of x will be
[tex]8x - 16 = 0\\x = 2[/tex]
Then again differentiate the function, if the value comes negative then maxima and if the value is positive then minima.
[tex]f''(x) = \dfrac{d }{dx} f'(x) \\\\f''(x)=8x - 16 \\\\f''(x) = 8\\\\ f''(x) > 0[/tex]
Then the function is minimum at 2.

Triangle similarity problem
Answer:
ST = 16
Step-by-step explanation:
The similar triangles are given as triangle PQR similar to triangle STU.
That makes sides PQ and ST corresponding sides. It also makes sides PR and SU corresponding sides. The ratios of the lengths of corresponding sides of similar triangles are equal.
[tex] \dfrac{ST}{PQ} = \dfrac{SU}{PR} [/tex]
[tex] \dfrac{5x + 1}{36} = \dfrac{11x - 5}{63} [/tex]
Multiply both sides by 9.
[tex] \dfrac{5x + 1}{4} = \dfrac{11x - 5}{7} [/tex]
Cross multiply.
[tex] 7(5x + 1) = 4(11x - 5) [/tex]
Distribute on both sides.
35x + 7 = 44x - 20
Subtract 44x from both sides.
-9x + 7 = -20
Subtract 7 from both sides.
-9x = -27
Divide both sides by -9.
x = 3

Answer:
vertical angles theorem
Corresponding angles are two or more angles that have similar properties. Thus they have equal measures.
The required prove is given in the explanation below:
Considering the given diagram, it can be observed that:
<1 ≅ <3 and <2 ≅ <4 (vertically opposite angle theorem)
Also,
<5 ≅ < 7 and <6 ≅ <8 (vertically opposite angle theorem)
m ⊥ n and a ⊥ b (given)
Thus,
<1 + <2 + <3 + <4 = [tex]360^{o}[/tex] (sum of angles at a point)
Also,
<5 + <6 + <7 + <8 = [tex]360^{o}[/tex] (sum of angles at a point)
Therefore,
<1 ≅ <7 (corresponding exterior angle property)
Therefore by corresponding exterior angle theorem, <1 ≅ <7.

A company paid $ 391 for 15 bushes and 8 bonsai trees . They had to purchase 9 more bushes and 5 more bonsai trees for $ 241 . What is the cost of each bush and bonsai tree ? the boxes below .
Answer:
Cost of one bush = x = $9
Cost of one bonsai tree = y = $32
Step-by-step explanation:
Let Cost of one bush = x
Cost of one bonsai tree = y
From the expression: A company paid $ 391 for 15 bushes and 8 bonsai trees
We made equation: [tex]15x+8y=391[/tex]
and From the expression: They had to purchase 9 more bushes and 5 more bonsai trees for $ 241 , we made equation: [tex]9x+5y=241[/tex]
Solving both equations simultaneously we can find value of x and y
Let:
[tex]15x+8y=391--eq(1)\\9x+5y=241--eq(2)[/tex]
We will use elimination method to solve these equations.
Multiply eq(1) by 5 and eq(2) by 8 and subtract
[tex]75x+49y=1955\\72x+40y=1928\\- \ \ \ - \ \ \ \ \ \ \ -\\--------\\3x=27\\x=\frac{27}{3}\\x=9[/tex]
So, value of x=9
Now finding value of y by putting value of x in equation 1
[tex]15x+8y=391\\Put \ x=9\\15(9)+8y=391\\135+8y=391\\8y=391-135\\8y=256\\y=\frac{256}{8}\\y=32[/tex]
So, value of y=32
Cost of one bush = x = $9
Cost of one bonsai tree = y = $32

Which equation best represents the relationship between x, the age of the automobile in years, and y, the value of the automobile in dollars
Answer:
y=-500x+22,000
Step-by-step explanation:
It's this one because the 22,000 shows the initial value of the automobile and -500x is how much value the automobile loses per year.
Answer:
Y = mx + c
C = 22,000

A hardware store sells power pack A, consisting of 4 D cells and 2 C cells for $12.60, and power pack B, consisting of 6 D cells and 4 C cells for $20.80. What is the price of each cell?
Answer:
The D cells are worth $2.20, and the C cells are worth $1.90.
Step-by-step explanation:
This can be written as:
4x + 2y = 12.60
6x + 4y =20.80
Our goal is to find one variable, then use that information to find the other.
If we multiply the top function by -1.5, we get:
-6x - 3y = -18.90
We can add this to the previous equation.
-6x - 3y = -18.90
+ 6x + 4y = 20.80
--------------------------
y = 1.90
The C cells are worth $1.90.
Plug this value into one of the other equations and solve for x.
4x + 2y = 12.60
4x + 2(1.90) = 12.60
4x + 3.80 = 12.60
4x = 8.80
x = 2.20
The D cells are worth $2.20.
Check these values in the other equation.
6x + 4y = 20.80
6(2.20) + 4(1.90) = 20.80
13.20 + 7.60 = 20.80
20.80 = 20.80
Answer:
C = $1.90 each
D = $2.20 each
Step-by-step explanation:
Given:
Power pack A: 4D + 2C = 12.60
Power pack B: 6D + 4C = 20.80
Isolate any one variable:
4D + 2C = 12.60
4D = 12.60 - 2C
D = 3.15 - 0.5C
Substitution to find cost of C cell battery:
6D + 4C = 20.80
6(3.15 - 0.5C) + 4C = 20.80
18.9 - 3C + 4C = 20.80
18.9 + C = 20.80
C = 1.90
Substitution to find cost of D cell battery:
4D + 2C = 12.60
4D + 2(1.90) = 12.60
4D + 3.8 = 12.60
4D = 8.8
D = 2.20
