Answer:
we have:

=> r²h = 10.18 = 9.20 = 5.36 = 6.30 = 4.45 = 12.15
=> only r²h = 5.36 satisfy the problem
=> h = 5
h = 5 r = 6
h = 5 r = 6=> d = 12
Answer:
g=7
Step-by-step explanation:
-2=g-9
switch sides
g-9= -2
add 9 to both sides
g-9+9= -2+9
simplify
g=7
Answer:
t ∈ {1, 3}
Step-by-step explanation:
You want to find t such that ...
h = 27
27 = -8t^2 +32t +3 . . . . . . substitute the expression for h
24 = -8t^2 +32t . . . . . . . . . subtract 3
-3 = t^2 -4t . . . . . . . . . . . . . divide by -8
1 = t^2 -4t +4 = (t -2)^2 . . . . add 4 to complete the square
±√1 = t -2 . . . . . . . . . . . . . . take the square root
t = 2 ± 1 . . . . . . . . . . . . . . . . add 2
t = 1 or 3
The object is 27 ft off the ground at t = 1 and again at t = 3.
Answer:
1 = 52
2 = 68
3 = 40
4 = 25
Step-by-step explanation:
1 = (4 + 3)^2 + (12 / 4)
7^2 + 3
49 + 3
= 52
2 = (12 x 9 - 7^2) + 9
(108 - 49) + 9
59 + 9
= 68
3 = (30 - 2) / 7 + 6^2
28 / 7 + 36
4 + 36
= 40
4 = (2 x 7 + 4^2) - 5
(14 + 16) - 5
30 - 5
= 25
Hope this helps!! Brainliest plz??
Given,
567 + x = 1257
=> x = 1257 - 567
=> x = 690
Option c is correct.
