Answer:
1.8 m
Step-by-step explanation:
h(T)=-9.8T^2+20T+1
just replace the T with 2
h=-9.8(2^2)+20(2)+1
-9.8×4+40+1=1.8m
1.8m
2x - 5y = 11. (4, a). x = 4, y = a
Substituting into 2x - 5y = 11
2(4) - 5(a) = 11
8 - 5a = 11
-5a = 11 - 8
-5a = 3
a = 3/-5 = -3/5 =- 0.6
Other coordinate = -3/5 = -0.6
Answer:
okay so the area is 8.478cm2
Answer:
1st option
Step-by-step explanation:
to find f(g(x)) substitute x = g(x) into f(x) , that is
f(g(x))
= f(4x - 5)
= 2(4x - 5) + 1 ← distribute parenthesis
= 8x - 10 + 1
= 8x - 9
