Answer:
The answer to question 3 is B.
Step-by-step explanation:
Answer:
Perimeter of the Quadrilateral=20.78
Step-by-step explanation:
Perimeter of the Quadrilateral= AB+BC+CD+AD
Finding the sides of the quadrilateral using the Distance formula:
A(-3,0), B(2,4), C(3,1) and D(-4,-3)


BC=




Perimeter of the quadrilateral= AB+BC+CD+AD
=6.40+3.16+8.06+3.16
=20.78
P=2(L+W)
L=2/3x+10
W=1/3x+5
P=2(2/3x+10+1/3x+5)
P=2(2/3x+1/3x+10+5)
P=2(3/3x+15)
P=2(x+15)
P=2x+30
D is most likely right. Basically, I would turn them into decimals and divide using a graphing calculator.
Answer:
Height after 5 seconds is <em>215 ft</em>
Step-by-step explanation:
Given that:
The initial velocity of object which is projected upwards is 123 ft/sec.
Height of the object, <em>h</em> after time <em>t </em> in seconds, is given as:

Here, <em>t </em>will always be positive, so
and
will also be positive.
But coefficient of
is negative, that means something is subtracted from the positive term
.
To find:
Height of object after 5 seconds.
Solution:
Given that
seconds.
Let us put the value in the given relation of
and
:

So, height after 5 seconds is <em>215 ft</em>.
