Find the arc length of the curve on the given interval. Parametric Equations Interval x = 6t + 5, y = 7 − 5t −1 ≤ t ≤ 3
Answer:
31.241
Step-by-step explanation:
x = 6t + 5, y = 7 − 5t −1 ≤ t ≤ 3
dx/dt = 6
dy/dt = -5
The arc length of the curve can be calculated below as
L = ∫[tex]\sqrt{(\frac{dx}{dt} )^2 + (\frac{dy}{dt})^2 dt }[/tex]
= [tex]\int\limits^3_ {-1} \, \sqrt{36 + 25 dt}[/tex]
= [tex]\sqrt{61} \int\limits^3_ {-1} \, dt[/tex]
= [tex]\sqrt{61} [3-(-1)][/tex]
= 4[tex]\sqrt{61}[/tex] = 31.241

Solve the absolute value equation. 4|4x - 3| - 8 = -4
Answer:
x = [tex]1,\frac{1}{2}[/tex]
Step-by-step explanation:
[tex]4|4x-3|-8=-4\\[/tex]
Add 8 to both sides;
4|4x - 3| = 4 4|4x - 3| = -4
Divide both sides by 4;
4x - 3 = 1 4x - 3 = -1
Add 3 to both sides;
4x = 4 4x = 2
Divide both sides by 4;
x = 1 x = [tex]\frac{1}{2}[/tex]

determine the size of V
Answer:
Size of V = 95°
Step-by-step explanation:
The total sum of angles in a triangle is 180°
You can find Angles T and V.
2x+3x+5 = 180°-25°
5x+5 = 155°
5x = 155°-5
= 150°
x = 150°÷5
= 30°
Angle V = 3×30°+5
= 95°
MAQ Unit 4: Parallel and Perpendicular Lines Assessment 8. Acub cut for wheelchairs must meet ADA (Americans with Disabilities Act requirements. Find the measure of 21 (exterior to the triangle) in the diagram below. 78° 1
Answer:
168
Step-by-step explanation:
- first we need to find the third angle of the triangle, and since 180 is the sum of all angles, 180 - 90 - 78 = 12
- 12 is the interior angle at point 1, the exterior angle is 180 - 12 = 168
(here we use 180 because its a straight line)
The measure of 21 (exterior to the triangle) is 168 degrees.
The calculation is as follows:
The third angle for the triangle is= 180 - 90 -78
= 12
Now the exterior angle should be= 180 - 12
= 168
Therefore we can conclude that the measure of 21 (exterior to the triangle) is 168 degrees.

Answer:
-3x+1y=-1
or
3x-1y=1
or
by multiplying with 1/3 the first equation we get
-1x+1/3y=-1/3
or from second equation
1x-1/3y=1/3
Step-by-step explanation:
y-y1=m(x-x1)
y1=-7
x1=-2
m=3
so
y-(-7)=3(x-(-2))
y+7=3(x+2)
y+7=3x+6
-3x+y=6-7
-3x+ 1y= -1

Can someone explain step by step
Answer:
Check below for step-by-step guide.
Step-by-step explanation:
a) Recall the formula for area is length times width. You are given both of those values. Width= (5x+2) and length = (4x-1). All you have to do is multiply them. You will get a quadratic!
b) This is just basically a lot of plugging in to the equation: Volume= length x width x height. So let's look at what we have!
It says our volume is 20x^3 + 63x^2+ 7x-6
It says our width is : (5x+2)
It says out length is (4x-1).
So the volume = l x w x h , we just plug in those numbers I listed above :
20x^3 + 63x^2+ 7x-6= (4x-1) (5x+2) (height)
Now remember you already multiplied length times width in problem (a). You can use that expanded quadratic on the right side. Then subtract values and isolate height!
You asked for an explanation of what to do step by step, so if you actually need help solving it, comment please! :)
is (11,9), (11,5), (9,3) a function
Answer:
[tex]\huge{ \boxed{ \sf{No}}}[/tex]
✑ Question :
Is ( 11 , 9 ) , ( 11 , 5 ) , ( 9 , 3 ) a function ?No , it's not a function.
✎ Reason :
This is not a function because one element 11 of set A is associated to elements 9 and 5 of set B.
♨ Explore about function :
↪ Function is a special type of relation. It is the refinement of relation. In a relation from A to B , every element of set A should have only one ( distinct ) image in B to be a function. In other words , if no two different ordered pairs have the same first component , then it is a function.

what is 4x + 9 = 68 in the clearest number possible
Answer:
x = 59/4
Step-by-step explanation:
4x + 9 = 68
Subtract 9 from both sides.
4x + 9 - 9 = 68 - 9
4x = 59
Divide both sides by 4.
4x/4 = 59/4
x = 59/4
Answer:
X=0.75
Step-by-step explanation:
Step 1:
68-9=59
Step 2:
59 divided by 4= 14.75
Step 3:
0.75=3/4
14 3/4=14.75
Solution:
X=0.75
Another way is 59/4=14.75

A 2,100-square-foot home in Cheyenne, WY , costs $110 per square foot. How much does this home cost? (Do not enter anything but numbers for the answer or it will count it wrong. Follow directions please because I am not coming back to grade if you mess up)
$231,000.
Step-by-step explanation:We have been given that a 2,100 square foot home in Cheyenne Wyoming costs $110 per square feet.
To find the total cost of home we will multiply the total area of home by the cost of per square feet area.
The total cost of home:2,100 × 110 = 231,000$
The sum of 2 numbers is 50. The sum of 1/4 of the first number and 2/3 of the second number is 25.What are the numbers?
HELLLLLPPPPPP
Answer:
First number: 20
Second number: 30
Step-by-step explanation:
First#: x
Second#: y
Constraints:
x + y = 50
1/4x + 2/3y = 25
Isolate variable y:
x + y = 50
-1/4 (x + y = 50 )
-1/4x - 1/4y = -12.5
Add equations the two equations to eliminate x:
-1/4x - 1/4y = -12.5
1/4x + 2/3y = 25
_________________
5/12y = 12.5
5y = 150
y = 30
Substitution to find x:
x + y = 50
x + 30 = 50
x = 20

Find the volume of the tetrahedron with the given vertices. (2, 0, 0), (0, 4, 0), (0, 0, 4), (2, 4, 4)
Answer:
The volume of the tetrahedron is
[tex]\frac{-32}{3}[/tex]
Step-by-step explanation:
To find the volume of a tetrahedron with vertices (2, 0, 0), (0, 4, 0), (0, 0, 4), (2, 4, 4).
We know by definition that the volume of a tetrahedron with vertices [tex](x_{1}, y_{1}, z_{1}), (x_{2}, y_{2}, z_{2}), (x_{3}, y_{3}, z_{3})[/tex] is
[tex]\frac{1}{6}\begin{vmatrix}
2 & 0 & 0 & 1\\
0 & 4 & 0 & 1\\
0 & 0 & 4 & 1\\
2 & 4 & 4 & 1
\end{vmatrix}[/tex]
From here we have:
[tex]\frac{1}{6}\begin{vmatrix}
x_1 & y_1 & z_1 & 1\\
x_2 & y_2 & y_2 & 1\\
x_3 & y_3 & z_3 & 1\\
x_4 & y_4 & y_4 & 1
\end{vmatrix}[/tex]
Finding the determinant of that matrix we have:
[tex]\frac{1}{6} (-64)[/tex] = [tex]\frac{-32}{3}[/tex]
