Step-by-step explanation:
—Dimension1 =25 and dimension2 =4
Area=25*4=100
Perimeter=2(25+4)=2(29)=58.
—-Dimension1 =12.5 and dimension2 =8
Area=12.5*8=100
Perimeter=2(12.5 + 8)=2(20.5)=41

Answer:
176 199 pounds
Step-by-step explanation:
To answer this it is first useful to find the proportionality constant.
F= kx
8080 pounds = k.88 in
k = 91.81 pound/inch
So what force is required to stretch the spring to 1919 inches?
F = kx
= 91.81 pound/inch * 1919 inches
= 176 199 pounds
It is worth noting that this force seems rather large and the spring might have long reached its elastic limit
Answer:
4.2
Step-by-step explanation:
Divide 1000 by 236 and you will get that result.
Answer:
As per the statement:
The path that the object takes as it falls to the ground can be modeled by:
h =-16t^2 + 80t + 300
where
h is the height of the objects and
t is the time (in seconds)
At t = 0 , h = 300 ft
When the objects hit the ground, h = 0
then;
-16t^2+80t+300=0
For a quadratic equation: ax^2+bx+c=0 ......[1]
the solution for the equation is given by:
On comparing the given equation with [1] we have;
a = -16 ,b = 80 and c = 300
then;
Simplify:
= -2.5 sec and = 7.5 sec
Time can't be in negative;
therefore, the time it took the object to hit the ground is 7.5 sec
Easy:
formula for parallelogram is b times h
so 5 times 14 =
70 sq mm.
