Answer:
t = 1.277 sec and t = 2.848 sec
Step-by-step explanation:
This problem is much more easily done by graphing it than by computing it using algebra.
The values of t we're looking for are the ones that make x = 0, so we want the solutions of 
on the interval [0, 3].
According to the graph, this is true when t = 1.277 seconds and t = 2.848 seconds.
ANSWER
The product is
EXPLANATION
To find the product of
and
means we should multiply the two fractions.
We multiply to obtain,
Cancel the common factors:
Now, multiply the numerators separately and the denominators too separately.
This simplifies to,
Answer:
25
Step-by-step explanation:
ad(wsaa)sf12345
First square both sides to get:
c + 22 = (c + 2)^2
or
c + 22 = c^2 + 4c + 4
Move the terms on the left side to the right side:
c^2 + 3c - 18 = 0
Factor to get:
(c + 6) * (c - 3) = 0.
The solutions are c = -6 and c = 3.
Check to see if these answers work by plugging them into the original equation:
c = -6:
sqrt (-6 + 22) ?= -6 + 2
But, -6 + 2 is a negative number, and you can't get a negative from a square root. So, -6 is extraneous.
c = 3:
sqrt (3 + 22) ?= 3 + 2
5 = 5. So, 3 works.
The answer is: B
a. my opposite sides are parallel
FALSE. Only the basis sides are parallel.
<u>b. I am a quadrilateral </u>
TRUE. A trapezium has 4 sides.
c. I have all the sides equal
FALSE. The trapezium is a special shape in that it does not, unlike the square or rectangle, have to have any equal side lengths.
