I belive it might be a right triangle
Answer:
Step-by-step explanation:
a) the equation representing the parabola is expressed as
h = -16t² - 4t + 20
c) to determine the height after 25 seconds, we would substitute 25 for t into the given equation. It becomes
h = -16(25)² - 4(25) + 20
h = - 10000 - 100 + 20
h = - 10080
d) when the coin lands on the ground, the height would be 0. Therefore,
-16t² - 4t + 20 = 0
Dividing both sides of the equation by 4, it becomes
- 4t² - t + 5 = 0
- 4t² - 5t + 4t + 5 = 0
- t(4t + 5) + 1(4t + 5) = 0
- t + 1 = 0 or 4t + 5 = 0
t = 1 or t = - 5/4
Since t cannot be negative, then t = 1 second
Answer:
13
Step-by-step explanation:
The product of two negative numbers is positive. The absolute value of a number is its magnitude written with a positive sign.
6 -2(-1) +|-5|
= 6 + 2 + 5
= 13
Answer:
A B and D
Step-by-step explanation:
Answer: m∠2 = 160°, m∠3 = 20°.
Step-by-Step Explanation: We know that m∠1 = 160°.
The values of both m∠1 and m∠2 are equivalent, which means that m∠2 is also 160°. The interior angles of a rhombus always add up to 360°, and when we add both 1 & 2, we get 320°.
The <em>other</em> opposite ends of a rhombus's interior measures are also the same in value. ... To figure out what m∠3 is, let's do the following steps:
1. 360-320 = 40
This means that the remaining two angle measurements will add up to 40°.
2. 40/2 = 20.
The final missing angle; m∠3 = 20°.
3. There, done!! Good luck!
