Answer:
Step-by-step explanation:
h(t) = 841 - 16t
[Is this written correctly? The time is usually t^2, not t. I'll solve with the written equation, but check the equation]
The height at ground level is 0, so we want the value of t when h(t) = 0:
0 = 841 - 16t
-16t = -841
t = 53 seconds
One can also graph this formula and find the time to hit the ground at the point the line intersects the x axis (x = 0).
====
If the equation should have read h(t) = 841 - 16t^2, solve it as above, setting h(t) = 0.
t = (29/4) seconds
This can also be graphed.
Answer:
x=1 and x =5
Step-by-step explanation:
We want to know when it crosses the x axis (f(x) =0) . From the graph, we can see the x value when y=0 is x=1 and x =5
Answer:
we are given
length =3 yards and 16 inches
now, we can change it in inches
we know that
1 yard =36 inches
so, we get
length =3*36 inches and 16 inches
length=124 inches
now, we will check each option
option-A:
we can see that this is also 124 inches
so, this is TRUE
option-B:
4 yd 4 in
we can change into inches
we know that
1 yard =36 inches
4 yd 4 in=4*36 inches +4 inch
4 yd 4 in=144 in
this is not equal to 124 in
so, this is FALSE
option-C:
3 yd 1 1/2 in
we know that
1 yard =36 inches
3 yd 1 1/2 in =
3 yd 1 1/2 in =
this is not same as 124 in
so, this is FALSE
option-D:
2 yd 52 in
we know that
1 yard =36 inches
2 yd 52 in
2 yd 52 in
so, this is same
so, this is TRUE
option-E:
10 ft 4 in
we know that
1 feet =12 inches
so,
10 ft 4 in=12*10 +4 in
10 ft 4 in=124 in
this is same
so, this is TRUE
Step-by-step explanation:
So yes 124 is the same as 3 yards and 16 inches
Hope this helps!!!
Answer:
X Divided by 60
Step-by-step explanation:
It should be x divided by 60
A²+b²=c²
8²+b²=17²
64+b²=289
subtract 64 from both sides
b²=225
find the square root of both sides to isolate b
b = 15
15*2
LE = 30ft
