Answer: -30 ==> A
Step-by-step explanation:
a = 3 and b = −4
12(a • b + a2) + 6=
12(a • b + a^2) + 6=
12(3 • (-4) + 3^2) + 6=
12(-12 + 9) + 6=
12(-3)+6=
-36+6=
-(36-6)=-30 ==> A
Answer:
a) -30
Step-by-step explanation:
Given that,
→ a = 3
→ b = -4
Let's solve the problem,
→ 12(a × b + a²) + 6
→ 12(3 × -4 + (3)²) + 6
→ 12(-12 + 9) + 6
→ 12 × -3 + 6
→ -36 + 6 = -30
Hence, the answer is -30.

On Monday, Saffron bakes
324 pastries in the morning and some more in the
afternoon. She sells 584 pastries. At the end of the
day she has 52 pastries left. How many pastries did
she bake in the afternoon?
the number of pastries that she bake in the afternoon is equal to 312 pastries.
We are given that:
Saffron sells 584 pastries in the whole day and 52 pastries are left at the end of the day.
Now, we will use addition to find the total number of pastries that is being made in the day.
Total pastries = 584 + 52
Total pastries = 636
Now, she bake 324 pastries in the morning.
So, the number of pastries baked in the afternoon = 636 - 324
In afternoon = 312.
Therefore, we get that the number of pastries that she bake in the afternoon is equal to 312 pastries.

Using translation concepts, the coordinates of the vertices after a rotation 180º clockwise around the origin is:
S': (-4,-10), R'(-4,-3), U'(-8,-3) and T'(-8,-10).
What is a translation?A translation is represented by a change in the function graph, according to operations such as multiplication or sum/subtraction either in it’s definition or in it’s domain. Examples are shift left/right or bottom/up, vertical or horizontal stretching or compression, and reflections over the x-axis or the y-axis.
For this problem, the coordinates (x,y) of the vertices are given as follows:
S(4,10), R(4,3), U(8,3), T(8,10).
The rule for a rotation 180º clockwise around the origin is:
(x,y) -> (-x,-y).
Hence the vertices of the rotated image will be given as follows, applying the above rule:
S': (-4,-10), R'(-4,-3), U'(-8,-3) and T'(-8,-10).

Select the points that lie on the line. and the relationship between the coordinates x and y.

4/8, 2/8
Answer:
(4,2) and ([tex]\frac{4}{8}[/tex],[tex]\frac{2}{8}[/tex]) are lie on the line, and y = [tex]\frac{1}{2}[/tex] x , is showing the relationship of x and y coordinates of given line.Given that
The co-ordinates of line is (0,0) and (2,1).To find
The points that lie on the line, and The relationship between the coordinates x and y.So, according to the question
We have,
The X and Y co-ordinates of line (0,0) and (2,1).For finding any point that lie on line, first we have to find the slope of given line,
So, we know that
slope (m) = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]
Where,
x₁ = 0 and x₂ = 2
y₁ = 0 and y₂ = 1
Now, putting the values, we will get
(m) = [tex]\frac{1-0}{2-0}[/tex] = [tex]\frac{1}{2}[/tex]
m = [tex]\frac{1}{2}[/tex]
We know that, the equation of line
y-y₁ = m(x- x₁ )
y-0 = [tex]\frac{1}{2}[/tex] (x- 0)
y = [tex]\frac{1}{2}[/tex] x -------------(1)
{ this equation (1) is showing a relationship the coordinates x and y }
For finding which point is lie in that line, this point must be prove that equation (1).
Now, let's check the points
For point (4,2)
y = [tex]\frac{1}{2}[/tex] x -------------(1)
2 = [tex]\frac{1}{2}[/tex] × 4
2 = 2
So, point (4,2) lie in this line.
For point (4,3)
y = [tex]\frac{1}{2}[/tex] x -------------(1)
3 = [tex]\frac{1}{2}[/tex] × 4
3 ≠ 2
So, point (4,3) not lie in this line.
For point (7,2)
y = [tex]\frac{1}{2}[/tex] x -------------(1)
2 = [tex]\frac{1}{2}[/tex] × 7
2 ≠ [tex]\frac{7}{2}[/tex]
So, point (7,2) not lie in this line.
For point ([tex]\frac{4}{8}[/tex],[tex]\frac{2}{8}[/tex])
y = [tex]\frac{1}{2}[/tex] x -------------(1)
[tex]\frac{2}{8}[/tex] = [tex]\frac{1}{2}[/tex] × [tex]\frac{4}{8}[/tex]
[tex]\frac{2}{8}[/tex] = [tex]\frac{2}{8}[/tex]
So, point ([tex]\frac{4}{8}[/tex],[tex]\frac{2}{8}[/tex]) lie in this line.
(4,2) and ([tex]\frac{4}{8}[/tex],[tex]\frac{2}{8}[/tex]) are lie on the line, and y = [tex]\frac{1}{2}[/tex] x , is showing the relationship of x and y coordinates of given line.

If an arrow is shot upward on the moon with a velocity of 58 m/s, its height in meters after t seconds is given by y=58t−.83t2.
(a) Find the average velocity over the given time intervals:
(1) [1,1.5]
(2) [1,1.1]
(3) [1,1.01]
(4) [1,1.001]
(b) Find the instantaneous velocity after one second (to the nearest hundredth).
(1) m/s
(2) m/s
(3) m/s
(4) m/s
(b) m/s
The 58 m/s initial velocity of the arrow with height, y = 58•t - 0.83•t², gives;
(1) 55.925 m/s
(2) 56.257 m/s
(3) 56.3317 m/s
(4) 56.33917 m/s
(b) 56.34 m/s
How can the average and instantaneous velocity be calculated?Initial velocity of the arrow = 58 m/s
Height of the arrow is; y = 58•t - 0.83•t²
The above kinematic equation can be analyzed as follows;
(1) The height at t = 1 is found as follows;
y = 58 × 1 - 0.83 × 1² = 57.17
Height at t = 1.5 s. is y = 58×1.5 - 0.83×1.5² = 85.1325
Average velocity = ∆y/∆tWhich gives;
Average velocity = (85.1325-57.17)/(1.5-1) = 55.925
The average velocity in the interval [1, 1.5] is therefore;
55.925 m/s(2) [1, 1.1]
Height at t = 1.1 s. is y = 58×1.1 - 0.83×1.1² = 62.7957
Which gives;
Average velocity = (62.7957-57.17)/(1.1-1) = 56.257
The average velocity is 56.257 m/s(3) [1, 1.01]
Height at t = 1.01 s. is y = 58×1.01 - 0.83×1.01² = 57.733317
Which gives;
Average velocity = (57.733317-57.17)/(1.01-1) = 56.3317
The average velocity is 56.33 m/s
(4) [1, 1.001]
Height at t = 1.01 s. is y = 58×1.001 - 0.83×1.001² = 57.22633917
Which gives;
Average velocity = (57.22633917-57.17)/(1.001-1) = 56.33917
The average velocity is 56.33917 m/s(b) The equation for the instantaneous velocity is found as follows;
v = dy/dt = 58 - 2×0.83•t
After 1 second, we have;
t = 1
v = 58 - 2×0.83 × 1 = 56.34
The instantaneous velocity at t = 1 seconds is 56.34 m/s

A toilet manufacturer has decided to come out with a new and improved toilet. The fixed cost for the production of this new toilet line is $16,600 and the variable costs are $67 per toilet. The company expects to sell the toilets for $157. Formulate a function P(x) for the total profit from the production and sale of x toilets.
The function P(x) for the total profit from the production and sale of x toilets is P(x) = 90x - 16600
How to formulate a function P(x) for the total profit from the production and sale of x toilets?The given parameters are
Fixed cost = 16600
Variable cost = 67 per toilet
Cost of toilet = 157 per toilet
Let the number of toilets be x
So, the cost function is
C(x) = Fixed cost + Variable cost * Number of toilets
This gives
C(x) = 16600 + 67x
Also, we have the revenue function to be
R(x) = Cost of toilet * Number of toilets
This gives
R(x) = 157x
The function P(x) for the total profit from the production and sale of x toilets is
P(x) = R(x) - C(x)
So, we have
P(x) = 157x - 16600 - 67x
Evaluate
P(x) = 90x - 16600
Hence, the function P(x) for the total profit from the production and sale of x toilets is P(x) = 90x - 16600
