AB = AD and BC = DC are given. Furthermore, we can see that AC = AC by the reflexive property. We have three pairs of congruent corresponding sides, which allows us to use the SSS congruence theorem. From that, we would use CPCTC to conclude that angle B is congruent to angle D.
CPCTC = corresponding parts of congruent triangles are congruent.
Answer:
2.35 yards/second or 7.07 ft/second
Step-by-step explanation:
The distance to be covered is 55 yards.
The casting cools at the rate of 
and the temperature must not be allowed to cool more than 
.
We know that, 
By the time, the temperature reaches , it will take about,
, so it will take about 23.33 seconds.
Also, 55 yards = 
So the minimum speed that conveyor must move is,
Hence, the speed of conveyor is 7.07 feet per second.
Answer:
Option (2)
Step-by-step explanation:
Given equation is,
x⁴- 9x² + 8 = 0
Let x² = t
By substituting the value of x²= t in the equation,
t² - 9t + 8 = 0
t² - 8t - t + 8 = 0
t(t - 8) - 1(t - 8) = 0
(t - 1)(t - 8) = 0
(t - 1) = 0 ⇒ t = 1
(t - 8) = 0 ⇒ t = 8
Since, t = x²
x² = 1 ⇒ x = ±1
x² = 8 ⇒ x = ±2√2
Therefore, Option (2) will be the correct option.
