The figure shows two wires diverging from an intersection point at an angle of 20°. A vertical rod is located a distance x from the intersection point and is moving to the right at speed s. What is the rate of change of the area, dA/dt, formed by the two wires and the rod?
A. dA/dt = (1/2(s)tan20)x
B. dA/dt = (1/2tan20)x
C. dA/dt = ((s)tan20)x
D. dA/dt = (tan20)x
E. dA/dt = (2(s)tan20)x
Answers
Answer:
dA/dt = ( (S)tan20°)x
Option C) dA/dt = ((s)tan20)x is the correct Answer
Step-by-step explanation:
Given the data in the question and given figure in the image;
The second image mages a triangle ΔAOB
using SOH CAH TOA
such that;
tan = 0pp/adj
tan20° = AB / AO
tan20° = AB /x
AB = xtan20°
given; dx/dt = S
now, know that the area of a triangle is 1/2base×height
so Area of ΔAOB will be;
A = 1/2 × AO × AB
we substitute in AB = xtan20° and AO = x
A = 1/2 × x × xtan20°
A = 1/2 × x²tan20°
dA/dx = ( 1/2×2xtan20°)
dA/dx = ( xtan20°)
now
dA/dt = dA/dx × dx/dt
we substitute
dA/dt = ( xtan20°) × S
dA/dt = ( (S)tan20°)x
Therefore; Option C) dA/dt = ((s)tan20)x is the correct Answer

Which graph represents (x,y)-pairs that make the equation y=0.5+5 true?
Choice B: (1,0), (3,4), (6,10)
Choice C: (2,6), (4,7), (6,8)
Answers
Answer:
Choice C
Step-by-step explanation:
Notice that the equation y = 0.5 x + 5
is a linear equation so the points that are solutions of it must reside on a line. Option A does not show aligned points, so it cannot be a possible answer.
Option B: we look into the given points and notice that just the first one (1, 0) is NOT a solution to the equation because:
y = 0.5 (1) + 5 = 5.5 and not "0"
Option C: This is the correct answer, since all those points satisfy the equation
Point (2, 6) --> y = 0.5 (2) + 5 = 1 + 5 = 6
Point (4, 7) --> y = 0.5 (4) + 5 = 2 + 5 = 7
Point (6, 8) --> y = 0.5 (6) + 5 = 3 + 5 = 8

Answer:
12 cows - 48 legs
4 ducks- 8 legs
- there are many different numbers you can do but if you want to change the numbers and have more ducks then: for every one cow you take away two more ducks.
Step-by-step explanation:
22 total animals
56 total legs
ducks have 2 legs
cows have 4 legs
12 times 4 = 48 ( 12 cows with 4 legs each cow = 48 legs)
4 times 2 = 8 ( 4 ducks with 2 legs each duck = 8 legs)
Creating a system of equation using the scenario described, the number of cows and ducks owned are 6 and 16 respectively.
Number of legs per cow = 4 Number of legs per duck = 2 Number of ducks = dNumber of cows = cThe equation goes thus :
c + d = 22 - - - (1)
4c + 2d = 56 - - - (2)
From (1)
c = 22 - d - - - - (3)
Substitute (3) into (2)
4(22 - d) + 2d = 56
88 - 4d + 2d = 56
88 - 2d = 56
-2d = 56 - 88
-2d = - 32
d = 16
From (3)
c = 22 - 16
c = 6
Hence, the number of cows and ducks owned are 6 and 16 respectively.

Correct answer: -2/5y + 8/5
Add -2y to both sides.
5x+ 2y +-2y = 8+ -2y
5x = -2y + 8
Divide both sides by 5
5x/5 = -2y +8/5
2. Y=3x - 7
Correct answer: 1/3y+ 7/3
Flip the equation
3x- 7=y
Add both sides by 7
3x -7 +7 =y+7
3x = y+7
Divide both sides by 3
3x/3= y+7/3

Describe the transformation f(x) = Vx+ 1 - 5 in words.
The parent function f(x) = V has been shifted
1 unit and
5 units
Answers
Answer:
The translation is 1 unit to the left and 5 units down
Step-by-step explanation:
The explanation is given below;
Given that
The transform function is [tex]f(x) = \sqrt{x+1} - 5[/tex]
It can be seen that
The parent function is
[tex]f(x) = \sqrt{x}[/tex]
After that
The parent function would be transform 1 units to the left [tex]\sqrt{x+1}[/tex]
And afterwards it would be transform in 5 units down [tex]\sqrt{x+1} - 5[/tex]
So
The parent function [tex]f(x) = \sqrt{x}[/tex] would be translate in 1 unit to the left and 5 units down
Answer:
The translation is 1 unit to the left and 5 units down

It is B i think i hope this helps
Step-by-step explanation:
If a line is perpendicular to a circle's radius at its outer endpoint, then the line is _Tangent_ to that circle.
What is tangent to a circle?A line segment which touches a circle specified to only one point is called a tangent to that circle.
A line segment is a straight line with finite length, and thus, have to endpoints(points on either ends).
If there is circle O with tangent line L intersecting the circle at point A, then the radius OA is perpendicular to the line L.
We need to find the if a line is perpendicular to a circle's radius at its outer endpoint, then the line is _____(what) to that circle.

The relationship shown for the flour and the cost is that of a direct variation because the graph is a straight line, noting that the increase of one variable causes also the increase to the value of the other. The point (1, 0.75) means that every pound of flour costs 0.75 dollar. From the graph given, the bakery will have to pay approximately $30 for 40 pounds of flour.
