I don't know the last one.
Answer:
12.68
Step-by-step explanation:
With reference angle 45°
perpendicular (p) = 9
hypotenuse (h) = c
Now
sin 45 ° = p/ h
0.71 = 9 / c
c = 9 / 0.71
c = 12.68
Hope it will help :)
V= πr^2xh
π=3.14
r=6ft
h=8ft
V=3.14x6^2x8=3.14x36x8=904.32ft^3
Answer:
Step-by-step explanation:
F(x) = 7 - 5x + 7x²
f(-9) = 7 - 5*(-9) + 7*(-9)²
= 7 + 45 + 7*81
= 7 + 45 + 567
= 619
Any transformation that is getting smaller is a dilation. Bigger, an enlargment. In this instance, it is a scale factor of 1/2, because scale factor 1 is congruent, greater than one an enlargement, less than one but greater than zero is a dilation.
