Answer:
4.97
Step-by-step explanation:
h(x) = -3x² + 5
h(0.1)
x = 0.1
h(0.1) = -3(0.1)² + 5
0.1² = 0.01
-3(0.01) + 5
-3(0.01) = -0.03
-0.03 + 5 = 4.97
2 x 7 = 14
5 x 7 = 35
7 x 7 = 2 x 7 + 5 x 7 = 14 + 35 = 49
You’re welcome

_______
Answer:
D
Step-by-step explanation:
Using the sine ratio in the right triangle and the exact value
sin45° = , then
sin45° = = = ( cross- multiply )
s × = ( divide both sides by )
s = = = = 4 → D
