Answer:
vertical angles theorem
Corresponding angles are two or more angles that have similar properties. Thus they have equal measures.
The required prove is given in the explanation below:
Considering the given diagram, it can be observed that:
<1 ≅ <3 and <2 ≅ <4 (vertically opposite angle theorem)
Also,
<5 ≅ < 7 and <6 ≅ <8 (vertically opposite angle theorem)
m ⊥ n and a ⊥ b (given)
Thus,
<1 + <2 + <3 + <4 = [tex]360^{o}[/tex] (sum of angles at a point)
Also,
<5 + <6 + <7 + <8 = [tex]360^{o}[/tex] (sum of angles at a point)
Therefore,
<1 ≅ <7 (corresponding exterior angle property)
Therefore by corresponding exterior angle theorem, <1 ≅ <7.

He then turns and travels for 1 mile on a street that is angled north from the first street by 35 degrees. He stops to rest. His pet bird escapes from home and flies directly to where he is resting. How far and in what direction does the bird fly?
Answer:
The bird flies 35 degrees north for about 3 to 4 miles
Answer:

1. Supposed that a ball is dropped from the upper observation deck of the Horizons 101 Tower 1., located
178 m above the ground. (a) What is the velocity of the ball after 5 sec? (b) How fast is the ball traveling
when it hits the ground?
Answer:
49m/s
59.07 m/s
Step-by-step explanation:
Given that :
Distance (s) = 178 m
Acceleration due to gravity (a) = g(downward) = 9.8m/s²
Velocity (V) after 5 seconds ;
The initial velocity (u) = 0
Using the relation :
v = u + at
Where ; t = Time = 5 seconds ; a = 9.8m/s²
v = 0 + 9.8(5)
v = 0 + 49
V = 49 m/s
Hence, velocity after 5 seconds = 49m/s
b) How fast is the ball traveling when it hits the ground?
V² = u² + 2as
Where s = height = 178m
V² = 0 + 2(9.8)(178)
V² = 0 + 3488.8
V² = 3488.8
V = √3488.8
V = 59.07 m/s

A radioactive substance decays according to the formula
Q(t)=Q0eâkt where Q(t) denotes the amount of the substance present at time t (measured in years),
Q0 denotes the amount of the substance present initially, and k (a positive constant) is the decay constant.
(a) Find the half-life of the substance in terms of k.
(b) Suppose a radioactive substance decays according to the formula
Q(t)=15eâ0.0001438t
How long will it take for the substance to decay to half the original amount? (Round your answer to the nearest whole number.) yr
Answer:
[tex]t=4820 y[/tex]
Step-by-step explanation:
a) The half-life equation is given by:
[tex]t_{1/2}=\frac{ln(2)}{k}[/tex]
b) Using the decay equation we have:
[tex]Q(t)=15e^{-0.0001438t}[/tex]
we need to find t when [tex]Q(t)=\frac{Q_{0}}{2}[/tex]
[tex]7.5=15e^{-0.0001438t}[/tex]
[tex]0.5=e^{-0.0001438t}[/tex]
[tex]ln(0.5)=-0.0001438t[/tex]
[tex]t=\frac{ln(0.5)}{-0.0001438}[/tex]
[tex]t=4820 y[/tex]
Therefore, it will take 4820 years to decay to half the original amount.

A hardware store sells power pack A, consisting of 4 D cells and 2 C cells for $12.60, and power pack B, consisting of 6 D cells and 4 C cells for $20.80. What is the price of each cell?
Answer:
The D cells are worth $2.20, and the C cells are worth $1.90.
Step-by-step explanation:
This can be written as:
4x + 2y = 12.60
6x + 4y =20.80
Our goal is to find one variable, then use that information to find the other.
If we multiply the top function by -1.5, we get:
-6x - 3y = -18.90
We can add this to the previous equation.
-6x - 3y = -18.90
+ 6x + 4y = 20.80
--------------------------
y = 1.90
The C cells are worth $1.90.
Plug this value into one of the other equations and solve for x.
4x + 2y = 12.60
4x + 2(1.90) = 12.60
4x + 3.80 = 12.60
4x = 8.80
x = 2.20
The D cells are worth $2.20.
Check these values in the other equation.
6x + 4y = 20.80
6(2.20) + 4(1.90) = 20.80
13.20 + 7.60 = 20.80
20.80 = 20.80
Answer:
C = $1.90 each
D = $2.20 each
Step-by-step explanation:
Given:
Power pack A: 4D + 2C = 12.60
Power pack B: 6D + 4C = 20.80
Isolate any one variable:
4D + 2C = 12.60
4D = 12.60 - 2C
D = 3.15 - 0.5C
Substitution to find cost of C cell battery:
6D + 4C = 20.80
6(3.15 - 0.5C) + 4C = 20.80
18.9 - 3C + 4C = 20.80
18.9 + C = 20.80
C = 1.90
Substitution to find cost of D cell battery:
4D + 2C = 12.60
4D + 2(1.90) = 12.60
4D + 3.8 = 12.60
4D = 8.8
D = 2.20

How are the signs of the coordinates of point A and point C related HURRY
Answer: They both are located at (2,3)
Step-by-step explanation:
The sign that A and C are related is that they both have the same distance from the y axis.
What are coordinates?a pair of numbers that employ the horizontal and vertical distinctions from the two reference axes to represent a point's placement on a coordinate plane. typically expressed by the x-value and y-value pairs (x,y).
Coordinates are always written in the form of small brackets the first term will be x and the second term will be y.
For example (5,3) here 5 will be for the x and 3 will be for the y.
Another example is (9,0) here 9 is for x and 0 is for y.
Given that the coordinates A and C how are related now as we can see that both A and C are the same amount of distance by the y-axis.
This also can be seen by the coordination of A and C.

Triangle similarity problem
Answer:
ST = 16
Step-by-step explanation:
The similar triangles are given as triangle PQR similar to triangle STU.
That makes sides PQ and ST corresponding sides. It also makes sides PR and SU corresponding sides. The ratios of the lengths of corresponding sides of similar triangles are equal.
[tex] \dfrac{ST}{PQ} = \dfrac{SU}{PR} [/tex]
[tex] \dfrac{5x + 1}{36} = \dfrac{11x - 5}{63} [/tex]
Multiply both sides by 9.
[tex] \dfrac{5x + 1}{4} = \dfrac{11x - 5}{7} [/tex]
Cross multiply.
[tex] 7(5x + 1) = 4(11x - 5) [/tex]
Distribute on both sides.
35x + 7 = 44x - 20
Subtract 44x from both sides.
-9x + 7 = -20
Subtract 7 from both sides.
-9x = -27
Divide both sides by -9.
x = 3
ST = 5x + 1 = 5(3) + 1 = 15 + 1 = 16
