Given: triangle ABC and triangle EDC, C is the midpoint of BD and AE.
Prove: AB || DE
Answers
Step-by-step explanation:
1. ΔABC=ΔCDE: a) according to the condition BC=CD and AC=CE; b) m∠(BCA)=m∠(DCE).
2. if ΔABC=ΔCDE, then m∠(BAC)=m∠(DEC) and m∠(ABC)=m∠(CDE).
3. if m∠(BAC)=m∠(DEC), then AB || DE (or if m∠(ABC)=m∠(CDE), then AB || DE).

Answers
Answer:
C) 1/6
Step-by-step explanation:
A probability is the number of desired outcomes divided by the number of total outcomes.
In this question:
We have 8 + 10 + 4 + 2 = 24 coins
Of those, 4 are nickels. So
[tex]p = \frac{4}{24} = \frac{1}{6}[/tex]

an object dropped from a height of 210ft will fall according to the equation h(t) =210-16t^2. how long will it take the object to reach the ground
Answers
Answer:
[tex]\sqrt{210/16}[/tex]
Step-by-step explanation:
By saying reach the ground, it means the altitude w[tex]\sqrt{}[/tex]ill be zero, so the equation will be: 210 - 16t^2 = 0
210 = 16t^2, t = [tex]\sqrt{210/16}[/tex]

Algebraically, find all remaining zeros of f(x) = 8x^3 - 6x^2-36x +27 in simplest form.
SHOW STEPS PLS
Answers
Answer:
[tex]x=-\frac{3\sqrt{2}}{2},\frac{3}{4},\frac{3\sqrt{2} }{2}[/tex]
Step-by-step explanation:
Given expression is,
f(x) = 8x³ - 6x² - 36x + 27
For zeros of the function,
f(x) = 0
8x³ - 6x² - 36x + 27 = 0
2x²(4x - 3) - 9(4x - 3) = 0
(2x² - 9)(4x - 3) = 0
(2x² - 9) = 0
x² = [tex]\frac{9}{2}[/tex]
x = [tex]\pm\frac{3}{\sqrt{2}}[/tex]
x = [tex]\pm \frac{3\sqrt{2}}{2}[/tex]
Or (4x - 3) = 0
x = [tex]\frac{3}{4}[/tex]
Therefore, all zeros of the given functions are [tex]x=-\frac{3\sqrt{2}}{2},\frac{3}{4},\frac{3\sqrt{2} }{2}[/tex].
Given that log 2 = 0.3010 and log 3 = 0.4771, evaluate log√120 and leave your answer correct to four significant figure
Answers
Answer:
1.040
Step-by-step explanation:
log √(120)
= (1/2) log 120
120 = 2³ • 3 • 5
= 0.5(3 log 2 + log 3 + log 5)
Express log 5 in terms of log 2.
log 5 = log (10/2) = log 10 - log 2 = 1 - log 2
= 0.5(3 log 2 + log 3 + 1 - log 2)
= 0.5(2 log 2 + log 3 + 1)
= 0.5(2*0.3010 + 0.4771 + 1)
= 1.03955 or 1.040

A senior employee who works 16 hours earns $39.50 more than a junior employee who works 18 hours. The senior employee earns $14 per hour. What is the hourly pay for the junior employee in dollars and cents?
(IN A TEST)
Answers
Answer:hourly pay for the junior employee in dollars and cents=$10.25
Step-by-step explanation:
Step 1
Total amount senior employee is being paid = amount per hour x hours worked
= $14 × 16 = $224.00
Total amount of junior employee since he/ she collects $39.50 less than senior employee= $224.00 - $39.50
= $184.50
Step 2
hourly pay of junior colleague= Total pay of junior colleague/ Hours worked
=$184.50 / 18 hours
= $10.25 per hour

Points A and B have the same x-coordinates but opposite y-coordinates. How many units away are each of the points from the y-axis?
3
4
6
7
Answers
Answer:
Each point is 4 units away from the y-axis.
Step-by-step explanation:
Coordinates of point (x, y) defines the distance of the point from y-axis and x-axis.
x-coordinate → distance from the y-axis
y-coordinate → distance from x-axis
Coordinates of A → (-4, 3)
Coordinates of B → (-4, -3)
So both the points have same x-coordinates but opposite y-coordinates.
Therefore, each point is 4 units away from the y-axis.
