Answer:
A.) 8x2 – 25x + 7
Step-by-step explanation:
The expression A² – (B + C) in its simplest form is 8x² – 25x + 7
Data obtained from the question A = 3x – 4B = x + 7C = x² + 2A² – (B + C) =? How to express A² – (B + C) in its simplest formA² – (B + C)
(3x – 4)² – (x + 7 + x² + 2)
9x² – 12x – 12x + 16 – (x + x² + 9)
9x² – 24x + 16 – x – x² – 9
9x² – x² – 24x – x + 16 – 9
8x² – 25x + 7
Thus,
A² – (B + C) = 8x² – 25x + 7

The position of a particle on a straight line is given by s(t) = 3 – cos(t).
A. Find velocity and acceleration at t = 4.3 s.
Round your answers to 2 decimal(s).
v(t) =
a(t) =
Given the position function
s(t) = 3 - cos(t )
differentiate once to get the velocity, and twice to get the acceleration:
v(t) = s'(t) = sin(t ) → v (4.3 s) ≈ -0.92
a(t) = s''(t) = v'(t) = cos(t ) → a (4.3 s) ≈ -0.40
The acceleration is negative, so the particle is slowing down.

There were 60 people on bus. 40% were female. How many people were females and how many were males?
Answer:
There were 24 females and 36 men on the bus
Step-by-step explanation:
To find the amount of females on the bus you multiply the 60 passengers by 0.4 to mimic the 40% and you get 24. So there were 24 females and to find the men you simply subtract 24 and 60 to get 36

The map of a biking trail is drawn on a coordinate grid. The trail starts at P(−6, 3) and goes to Q(3, 3). It goes from Q to R(3, −4) and then to S(6, −4). What is the total length (in units) of the biking trail?
Answer:
total length = 19 units
Step-by-step explanation:
Notice that the distance between the extremes of the first segment of the trail, is a horizontal segment of 9 units length.
The second segment from (3,3) to (3, -4) is vertical one of length 3 - -4 = 7 units.
The third segment of the trail from (3, -4) to (6, -4) is another vertical segment of length 6=3 = 3 units.
Therefore,the total length of the trail is 9 + 7 + 3 = 19 units

What is the boundary line for the linear inequality 4x + 2y < 18?
Answer:
Simplifying
x = 4.5 + -0.5y
Step-by-step explanation:
The boundary line of the inequality is intersecting the x-axis at 4.5.
The given inequality is 4x + 2y < 18.
What is the boundary line for linear inequality?A linear inequality divides the coordinate plane into two halves by a boundary line where one half represents the solutions of the inequality. The boundary line is dashed for > and < and solid for ≤ and ≥. The half-plane that is a solution to the inequality is usually shaded.
Graph the inequality by finding the boundary line, and then shading the appropriate area.
Now, 4x + 2y < 18 can be written as y<−2x+9.
The boundary line of the inequality is given below.
The boundary line of the inequality is intersecting the x-axis at 4.5.

Find the equation of a line with the given information:
f(- 6) = 8 and f( - 8) = – 1.
Wrote answer in point slope form
Answer:
[tex]y -8= \frac{9}{2}(x +6)[/tex]
Step-by-step explanation:
Given
[tex]f(-6) = 8[/tex]
[tex]f(-8) = -2[/tex]
Required
Determine the equation in point-slope form
The general function notation is:
[tex]f(x) = y[/tex]
So, in [tex]f(-6) = 8[/tex]
[tex](x_1,y_1) = (-6,8)[/tex]
[tex]f(-8) = -1[/tex]
[tex](x_2,y_2) = (-8,-1)[/tex]
Calculate the slope (m)
[tex]m = \frac{y_2 - y_1}{x_2-x_1}[/tex]
[tex]m = \frac{-1-8}{-8-(-6)}[/tex]
[tex]m = \frac{-1-8}{-8+6}[/tex]
[tex]m = \frac{-9}{-2}[/tex]
[tex]m = \frac{9}{2}[/tex]
The equation is then calculated as:
[tex]y -y_1= m(x-x_1)[/tex]
[tex]y -8= \frac{9}{2}(x - (-6))[/tex]
[tex]y -8= \frac{9}{2}(x +6)[/tex]

Determine whether each pair of figures is similar. If so, write the similarity statement and scale factor. If not, explain why. Number 1 and 2 on the second part.
9514 1404 393
Answer:
JKLM ~ QRSP, scale factor 0.6ΔABC ~ ΔUVT, scale factor 1.5Step-by-step explanation:
We can write the similarity statements by naming vertices in order of increasing numbers of arcs, starting with the one having a single arc. Then we can express the side lengths as a reduced ratio, in the same order.
1. JKLM ~ QRSP
JK : KL : LM : MJ = 20 : 15 : 24 : 25
QR : RS : SP : PQ = 12 : 9 : 14.4 : 15 = 20 : 15 : 24 : 25 (same ratios)
The scale factor is 12/20 = 0.6.
__
2. ΔABC ~ ΔUVT
AB : BC : CA = 16 : 14 : 12 = 8 : 7 : 6
UV : VT : TU = 24 : 21 : 18 = 8 : 7 : 6 (same ratios)
The scale factor is 24/16 = 1.5.
