Answer:
∠ 3 = 40°
Step-by-step explanation:
The sum of the 3 angles in a triangle = 180°
Subtract the sum of the 2 angles in Δ ABC for ∠ 1
∠ 1 = 180° - (58 + 90)° = 180° - 148° = 32°
∠ 2 = ∠ 1 = 32° ( vertical angles )
Thus
∠ 3 = 180° - (108 + 32)° = 180° - 140° = 40°
PLSSSSSSSS HELP! How do I find the domain AND range in the same graph??
Answers
Answer:
Step-by-step explanation:
Let's start with definitions.
Domain: Indicates the values that x can be, has a certain set
Range: Indicates the values that y can be, has a certain set
To find the domain of a graph, we want to see where all the x values fit. In the graph below's case, the domain would be -3<x≤1
To find the range, we need to see where all the y values fit. In the graph below's case, the range would be -4≤y<0.
Notice how some of them are < instead of ≤. This is because they have an open circle. When a point has an open circle, it means that point can't be included in the equation, hence the < instead of ≤

Veronica is ordering trophies for her school. Company P charges $3.50 for each trophy and a one-time engraving fee of $25. Company R charges $7.50 for each trophy and a one-time engraving fee of $17. Which inequality can be used to find x, the minimum number of trophies that can be ordered so that the total charge at Company P is less than the total charge at Company R?
Answers
Answer: Required inequality : [tex]3.50x+25<7.50x+17[/tex]
Solution: x<2.
Step-by-step explanation:
Let x = number of trophies.
Company P charges $3.50 for each trophy and a one-time engraving fee of $25.
Total charge for x trophies from Company P=[tex]3.50x+25[/tex]
Company R charges $7.50 for each trophy and a one-time engraving fee of $17.
Total charge for x trophies from Company R =[tex]7.50x+17[/tex]
When total charge at Company P is less than the total charge at Company R, then
[tex]3.50x+25<7.50x+17\\\\\Rightarrow\ 7.5x-3.5x<25-17\\\\\Rightarrow\ 4x<8\\\\\Rightarrow\ x<2[/tex]
Required inequality : [tex]3.50x+25<7.50x+17[/tex]
Solution: x<2.

What is the length of line segment YX? 8 units 8 StartRoot 3 EndRoot units 12 units 12 StartRoot 3 EndRoot units
Answers
Answer:
The correct answer would be 8 root symbol 3
Step-by-step explanation:
because i chose it and got it right
The length of the line segment YX is [tex]8\sqrt{3}[/tex] if the line XW is of 24 units.
What is a trigonometric function?It is a ratio of sides of a right angled triangle.
How to use Trigonometric functions?It can be seen that the diagonal is making a right angle triangle XWV so
we will use the trigonometric function to determine the value of WV which will then be equal to XY because it is a rectangle.
tan(30)=VW/XW
1/[tex]\sqrt{3}[/tex]=VW/24
VW=24/[tex]\sqrt{3}[/tex]
VW=8[tex]\sqrt{3}[/tex] UNITS by multiplying and divide by root 3.
Hence the length of the side XY =8 root 3 units.

(−3, −5), because the point does not lie on any axis (−3, −5), because the point satisfies both equations (−4, −8), because the point satisfies one of the equations (−4, −8), because the point lies between the two axes
Answers
Answer:
The point (-3,-5) is the solution of the system because it satisfies both equations
Step-by-step explanation:
System of equations
A system of equations represents a situation where multiple conditions apply, and the possible solution to the system, if any, must satisfy all conditions, not just some of them.
We have the system of equations:
[tex]\left\{\begin{matrix}y=x-2\\ y=3x+4\end{matrix}\right.[/tex]
The solution of the system is an ordered pair (x,y) that satisfies both equations.
Test the point (-3,-5):
[tex]\left\{\begin{matrix}-5=-3-2=-5\\ -5=3*(-3)+4=-9+4=-5\end{matrix}\right.[/tex]
We can see both equalities are true, thus the point (-3,-5) is the solution of the system because it satisfies both equations

much profit did they make from selling each calendar? How much would they
have lost if they had sold no calendars?
Answers
Answer:
See my explanations below please :)
Step-by-step explanation:
4. y-1 = 3(x-2)
5. y+5= -2(x+3)
6. y+11 = (3/4)(x-4)
7. y = (-1/6)(x-4)
8. y+2 = (5/8)(x+3)
9. y-1 = (3/8)(x+5)
10. Because after simplifying them, the final equations are the same
11. so we have (80,-360) and (200, 600)
m = (600-(-360)) / (200-80) = 960 / 120 =8
=> y+360 = 8(x-80)
Profit selling each = the slope m = $8
Working backwards, when they sold 80 calendars they still have a loss of $360, so the original loss (when x=0) = 80*8 + 360 = 640 + 360 = $1,000

The volume of a circular cylinder is calculated using the formula = ^2*2ℎ. If the height ℎ is known to be equal to the diameter 2 and ℎ is measured at a percentage error of 2%, find the percentage error in calculating the volume of the cylinder.
Answers
Answer:
6%
Step-by-step explanation:
From the information given:
The height h is said to be equal to the diameter which is 2r
h = 2r
r = h/2
Recall that: The volume for calculating a circular cylinder is:
[tex]V = \pi r^2 h[/tex]
[tex]V = \pi (\dfrac{h}{2})^2 h[/tex]
[tex]V =\dfrac{\pi h^3}{2}[/tex]
[tex]\dfrac{dV}{dh} = \dfrac{3 \pi h^3}{4}[/tex]
Thus, the percentage error of the height can now be calculated as:
[tex]\dfrac{dh }{h} \times 100 = 2[/tex]
[tex]dh =\dfrac{h}{50}[/tex]
Now taking the differential of the volume, we have:
[tex]dV = \dfrac{dV}{dh}* dh[/tex]
[tex]dV = \dfrac{3 \pi h^2}{4}* \dfrac{h}{50}[/tex]
FInally, the %age change in the volume is calculated as follows:
[tex]\dfrac{dV}{V} = \dfrac{ \dfrac{3 \pi h^2}{4}* \dfrac{h}{50}}{\dfrac{\pi h^3}{2}}[/tex]
[tex]\dfrac{dV}{V} = \dfrac{3}{50} \times 100 \%[/tex]
[tex]\dfrac{dV}{V} =6 \%[/tex]
Thus; the percentage error in calculating the volume of the cylinder is 6%
