s = -t³ + 2t² - 2t, 0 ≤ t ≤ 2 Find the body's speed and acceleration at the end of the time interval. *
A) -6 m/sec, -8 m/sec²
B) 6 m/sec, -8 m/sec²
C) 6 m/sec, -2 m/sec²
D) 2 m/sec, 0 m/sec²
Answer:
A
Step-by-step explanation:
the end of interval is t=2
v=s'= -3t^2+4t-2
v(2)= -3(2^2)+4(2) -2
v(2)=-12+8-2
v(2)= -6m/s
so tje ans is A
Does 2x-x equal to 2x or x? I thought it would be x, but in a video I'm watching for school, it says 2x.
Answer:
i also would say x maybe school did a mistake
What are the coordinates of the point on the directed line segment from (3, -3) to
(7,5) that partitions the segment into a ratio of 5 to 3?
Answer:
(5.5, 2)Step-by-step explanation:
Points given:
(3, -3) and (7,5)Partition ratio:
5 to 3Formula for the point:
x = x1 + a/(a+b)×(x2 - x1) y = y1 + a/(a +b)×(y2 - y1)So the points are:
x = 3 + 5/(5+3)×(7-3) = 3 + 5/8×4 = 5.5y = -3 + 5/8×(5 - (-3)) = -3 + 5/8×8= 2Answer:
(5.5,2)

2. Is the point (-3,-4) the solution to the system of
equations: SHOW ALL YOUR WORK.
Answer:
y = 2x + 2
-4 = 2(-3) + 2
-4 = -6 + 2
-4 = -4
y = x - 1
-4 = -3 - 1
-4 = -4
It is the solution
Step-by-step explanation:
Answer: Yes, it is the solution to the system.
=========================================================
Explanation:
The point (-3,-4) means that x = -3 and y = -4 pair up together.
Let's plug those values into the first equation and simplify
y = 2x+2
-4 = 2(-3)+2 .... replace x with -3; replace y with -4
-4 = -6+2
-4 = -4 ... we get a true equation
Let's repeat for the other equation as well
y = x-1
-4 = -3-1
-4 = -4 .... this is also true
Since both equations are true, this means (-3,-4) is the solution to the system. The two lines intersect at (-3,-4).
I will mark brainlist for this science question please. I need to figure out where to put where. And what percentages. Your choices of percentages is 0, 25, 50, 75, and 100.
Answer:
Long wings: 0
Short wings: 100
Step-by-step explanation:
Genotype of the flies: ww
The cross will yield the genotype ww and the flies will express the recessive phenotype which is short wings.
The probability for long wings will be 0 as there is no dominant allele present. The probability for short wings will be 100 as all the flies will have short wings.
Hope that helps.
Write the expression as a single natural logarithm.
3lnm+4lnn
Answer:
We conclude that:
[tex]3\ln \left(m\right)+4\ln \left(n\right)=\ln \left(m^3n^4\right)[/tex]
Step-by-step explanation:
Given the expression
[tex]3\ln \left(m\right)+4\ln \left(n\right)[/tex]
Apply log rule:
[tex]a\log _c\left(b\right)=\log _c\left(b^a\right)[/tex]So the expression becomes
[tex]3ln\:m\:+\:4ln\:n=\ln \:\left(m^3\right)+\ln \:\left(n^4\right)[/tex]
Apply log rule:
[tex]\log _c\left(a\right)+\log _c\left(b\right)=\log _c\left(ab\right)[/tex]
so the expression becomes
[tex]=\ln \left(m^3n^4\right)[/tex]
Therefore, we conclude that:
[tex]3\ln \left(m\right)+4\ln \left(n\right)=\ln \left(m^3n^4\right)[/tex]

The graph shows the cost of buying tickets to a concert.
a. What does the point (4,122) represent?
b.What is the unit rate?
c.What is the cost of buying 10 tickets?
Answer:
a) The point (4, 122) represents that the cost of 4 tickets is $122
b) The unit rate is 30.5 dollars per ticket
c) The cost of buying 10 tickets is $305
Step-by-step explanation:
Let us solve the question
From the given graph
∵ The x-axis represents the number of tickets
∵ The y-axis represents the cost of tickets in dollars
∴ The line represents the relationship between the number of tickets
and their cost
a)
∵ The point (4, 122) lies on the line
∴ x = the number of tickets
∴ y = their cost
∵ x = 4 and y = 122
∴ The cost of the 4 tickets is 122 dollars
∴ The point (4, 122) represents that the cost of 4 tickets is $122
b)
∵ The unit rate is the slope of the line
∵ The slope of the line = Δy/Δx, where
Δy = y2 - y1 Δx = x2 - x1∵ The line passes through points (0, 0) and (2, 61)
∴ x1 = 0 and x2 = 2
∴ y1 = 0 and y2 = 61
→ Substitute them in the rule of the slope above
∴ The slope of the line = [tex]\frac{61-0}{2-0}[/tex] = [tex]\frac{61}{2}[/tex] = 30.5
∴ The unit rate is 30.5 dollars per ticket
c)
∵ The linear equation is y = m x + b, where
m is the slope of the line b is the y-intercept (value y at x = 0)∵ m = 30.5 ⇒ the slope of the lone
∵ b = 0 ⇒ The line passes through the origin point (0, 0)
∴ The equation of the line is y = 30.5x
∵ x = 10 ⇒ number of tickets
→ Substitute x by 10 in the equation to find the cost of 10 tickets
∴ y = 30.5(10)
∴ y = 305
∴ The cost of buying 10 tickets is $305

Find the value of x in each case. Give reasons to justify your solutions! XW ∥ YZ
Answer:
The answer is "19".
Step-by-step explanation:
In this question, the graph file is missing which is defined in the attached file please find it.
When YZ and XW were identical,
[tex]\angle XWY =\angle WYZ \ \ \text{(Alternate Angles)}[/tex]
[tex]\angle XWY = 2x[/tex]
Because the angles are all 180 degrees in either a triangle:
[tex]\to (3x - 5) + 90 + 2x = 180\\\\\to 3x - 5 + 90 + 2x = 180\\\\ \to 5 x + 85= 180 \\\\ \to 5 x = 180-85 \\\\ \to 5x = 95 \\\\ \to x= \frac{95}{5} \\\\ \to x = 19[/tex]
The answer above is accually correct, but always remember when submitting your answer to always put the degrees sign.

Find the maximum value of
P = x + 6y
subject to the following constraints:
(2x + 4y < 10
X + 9y < 12
x > 0
y0
P = [?]
Answer:
(3, 1)
Step-by-step explanation:
Given the following constraints:
2x + 4y ≤ 10
x + 9y ≤ 12
x ≥ 0
y ≥ 0
We have to first graph the above constraints and secondly, we find the boundary points for the feasible region. This is done by plotting the graphs of 2x + 4y ≤ 10 and x + 9y ≤ 12.
From the graph, the following points satisfy the constraints:
(0,0) , (3,1) , (0,4/3) , (5,0)
Given that:
P = x + 6y
For (0, 0): P = x + 6y = 0 + 6(0) = 0
For (3, 1): P = x + 6y = 3 + 6(1) = 9
For (0, 4/3) P = x + 6y = 0 + 6(4/3) = 8
For (5, 0) P = x + 6y = 5 + 6(0) = 5

What is the number of cycles of y=1/8cos(5θ+π/6)+3 between 0 and 2π?
You are correct. The answer is B) 5.
This is because the period here is T = 2pi/5
Multiplying 5 with this period leads to 5*(2pi/5) = 2pi; showing that 5 full cycles occupy a total horizontal width of 2pi units (more specifically stretching from 0 to 2pi).
y is inversely proportional to the square of x.
A table of values for x and y is shown.

Graph the line y= -3/2x + 1
Answer:
Step-by-step explanation:
The graph of y= -3/2x + 1 is given in attachment with slope -3/2.
What is Slope of Line?The slope of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane.
The slope intercept form of a line is y=mx+b, where m is slope and b is the y intercept.
The slope of line passing through two points (x₁, y₁) and (x₂, y₂) is
m=y₂-y₁/x₂-x₁
The given line is y= -3/2x + 1
slope is -3/2
We have to find few values of x and y.
When x=0
y=1
When x=1
y=-1/2
When x=2
y=-2
Hence, the graph of y= -3/2x + 1 is given in attachment with slope -3/2.

Who can read the greatest number of pages in a day?
plz explain your answer
Answer:
Juan
Step-by-step explanation:
The number of pages that Ana, Hillary, Roger, and Juan can read in a day is shown below:
For Ana
Ana read 15% of her 46-page book.
= 15% × 46 pages
= 6.9 pages
For Hillary
Hillary read 11% of her 72-page book.
= 11% × 72 pages
= 7.92 pages
For Roger
Roger read 12% of his 68-page book.
= 12% × 68 pages
= 8.16 pages
For Juan
Juan read 14% of his 69-page book.
