What are the coordinates of the endpoints of the segment T'V'? T'(-3, 6) and V'(0, 3) T'(-3, 6) and V'(0, 1) T'(-1, 2) and V'(0, 3) T'(-1, 2) and V'(0, 1)
Answer:
Step-by-step explanation:
The figure required in the question is missing, the figure can be found in attachment.
Transforming points T and V according to the rule (x,y) -> (3/4x, 3/4y), we get:
T(-4, 8) -> (-4*3/4, 8*3/4) -> (-3, 6) which corresponds to T'
V(0, 4) -> (0*3/4, 4*3/4) -> (0, 3) which corresponds to V'

-5x-4y=2a 4x-5y=2 which of the following choices of A will results in a system of linear equations with exactly one solution
Answer:
Any of them. a ∈ RStep-by-step explanation:
-5x - 4y = 2a 4x - 5y = 2
-4y = 5x + 2a -5y = -4x + 2
y = (5x + 2a):(-4) y = (-4x + 2):(-5)
y = -⁵/₄x - ¹/₂a y = ⁴/₅x - ²/₅
m₁ = -⁵/₄, b₁ = -¹/₂a m₂=⁴/₅, b₂= -²/₅
-⁵/₄ ≠ ⁴/₅
Different slopes means that two lines have one point of intercept (no mater what the b's are). That means that the system of linear equations has exactly one solution for any value of a.

Suppose the newspaper states that the probability of rain today is 50%. What is the complement of the event "rain today"?
Answer:
50%
Step-by-step explanation:
Given that :
Let Probability of rain today = P(rain today) = 50% = 0.5
The complement of an event A denoted as A' means the opposite of event A is obtained by subtracting event a from 1.
P(rain today) = 0.5
The complement of P(rain today) ; means the probability that it will NOT rain today;
Hence, P(raintoday') = 1 - 0.5 = 0.5 = 50%

-25/40+(64/40) as a fraction (simplest form)
Answer:
39/40
Step-by-step explanation:
-25/40 + 64/40 already has a common denominator so you just need to add the numerators. -25 +64 = 39 over the denominator of 40.
39/40
Step-by-step explanation:
-5/8 + 16/10 = -5/8 + 8/5 = -25+64/40 = 39/40

Which equation is equivalent to 3 + 5(x + 2) = 12? A 8x + 16 = 12 B 8x + 2 = 12 C 5x + 5 = 12 D 5x + 13 = 12
Answer:
D 5x + 13 = 12
Step-by-step explanation:
3 + 5(x + 2) = 12
3 + 5x + 10 = 12
5x = -1
x = -1/5
D) 5x + 13 = 12
5x = 12 - 13 = -1
x = -1/5

Answer:
a) i) The drawing of Zeno's route is attached
ii) The bearing of Zeno's return journey is 241° from point C to point A
b) Yes, Zeno returns to Port A before 5.15pm
Step-by-step explanation:
a) i) Please find attached the drawing of Zeno's route
ii) From the attached diagram of Zeno's route created with Microsoft Whiteboard, we find the bearing of his return journey as 241° from point C to point A
b) The distance from point C to point A = 10·√5 km
The speed with which Zeno sails as he returns = 10 km/h
The time it takes Zeno to return t = Distance/Speed
∴ The time it takes Zeno to return t = 10·√5 km/(10 km/h) = √5 h ≈ 2.2361 hours ≈ 2 hours 14 minutes and 9.845 seconds
The time Zeno arrives at point A from point A ≈ 3.00 pm + 2 hours 14 minutes and 9.845 seconds = 5:14.1641 p.m. ≈ 5:14 pm.
Therefore, Zeno returns to Port A before 5.15pm.
A circular wire of length 176 cm is rebound to a rectangle whose length is same as the diameter of the circle. Find the difference in both the areas ?
Answer:
The difference in area is 672 cm^2
Step-by-step explanation:
Firstly, let us get the diameter of the circle
The length of the wire is the measure of the circle’s circumference
mathematically;
C = pi * d
176 = 22/7 * d
22d = 7 * 176
d = (7 * 176)/22
d = 56 cm
So, the area of the circle will be;
pi * d^2/4
= 22/7 * 56 * 56 * 1/4
= 2464 cm^2
Also, the length of the circumference is same as the perimeter of the rectangle
From the perimeter of the rectangle, we can get the width and use that to calculate the area of the rectangle
The formula for the perimeter of the rectangle is;
2(l + b)
2(56 + b) = 176
56 + b = 88
b = 88-56
b = 32 cm
So, the area of the rectangle will be;
32 * 56 = 1792 cm^2
The difference between the two areas will be;
2464-1792 = 672 cm^2

Q and D are points on a polygon. Q' D' are points of the polygon under a translation. Determine the translation. Write your answer as (x,y).
Q (4,5) Q' (9,-1)
D (-5,-2) D' (0,-8)
Answer:
The translation is (5, -6)
Step-by-step explanation:
If the point (x, y) translated h unit right and k unit up, then its image is (x + h, y + k) and the translation is (h, k)If the point (x, y) translated h unit left and k unit up, then its image is (x - h, y + k) and the translation is (-h, k)If the point (x, y) translated h unit right and k unit down, then its image is (x + h, y - k) and the translation is (h, -k)If the point (x, y) translated h unit left and k unit down, then its image is (x - h, y - k) and the translation is (-h, -k)Let us solve the question
∵ The coordinates of point Q are (4, 5)
∴ x = 4 and y = 5
∵ The coordinates of point Q' are (9, -1)
∴ x' = 9 and y' = -1
→ That means x increased and y decreased ⇒ 3rd case above
∴ The point Q is moved to the right and down
→ By using the 3rd rule above ⇒ (x + h, y - k)
∵ x + h = 9
∵ x = 4
→ Substitute x by 4
∴ 4 + h = 9
→ Subtract 4 from both sides
∵ 4 - 4 + h = 9 - 4
∴ h = 5
∵ y - k = -1
∵ y = 5
→ Substitute y by 5
∴ 5 - k = -1
→ Subtract 5 from both sides
∵ 5 - 5 - k = -1 - 5
∴ -k = -6
→ Divide both sides by -1
∴ k = 6
∵ The translation is (h, -k) in the 3rd case
∵ h = 5 and k = 6
∴ The translation is (5, -6)
We can check the rule by finding D' the image of the point D
∵ D = (-5, -2)
∵ D' = (x + h, y - k)
∵ D' = (-5 + 5, -2 - 6)
∴ D' = (0, -8) as the given point D'
∴ The translation is correct

Answer:
a) 3/5=12/20
b) 5/6=25/30
Step-by-step explanation:
a.) To find the answer you would first find how much it took to get to 20. 5 times 4 is 20. Then to find the numerator you would do 3 times 4 and that would be 12.
b) To find the answer you would first find how much it took to get to 30. So 30/6 is 5. Then you would divide 25 by 5 and you would get 5.

The population of new york city in 2013 was about 8,406,000 people which number best appoximates the population as a single digit times a power of ten
Answer:
8 * 10^6
Step-by-step explanation:
The question is asking us to represent the value 8,406,000 in standard. The standard form of an expression is expressed as;
A * 10^n
A is any integer between 1 and 10
n is any integer.
Given the value 8,406,000
8,406,000.
We are going to move the decimal point at the end to first digit value. This point will be shifted 6 times to have;
8,406,000 = 8.6 * 10^6 (Note that n is positive since the value given is greater than 1)
Since we are to express as a single digit times a power of ten, the required answer will be 8 * 10^6

1. slope
2. y-intercept
3. slope intercept form
(-5, 2) ⇒ x₁ = -5, y₁ = 2
(7, -1) ⇒ x₂ = 7, y₂ = -1
Slope:
[tex]\bold{m=\dfrac{y_2-y_1}{x_2-x_1}=\dfrac{-1-2}{7+5}=\dfrac{-3}{12}=-\dfrac14}[/tex]
Slope intercept form:
y = mx + b
Plug m and (7, -1) :
-1 = -¹/₄(7) + b
-1 + ⁷/₄ = b
b = ³/₄ ← y-interceptTherefore slope intercept form of h(x):
