Hello from MrBillDoesMath!
Answer:
f(-1) = 2
f(1) = 6
f(2) = 11
Discussion:
Let f(x) = 2x^3 - 3x^2 + 7. Then
f(-1) = 2 (-1)^3 - 3 (-1)^2 + 7 = -2 -3 + 7 = -5 + 7 = 2
f(1) = 2(1)^3 - 3(1)^2 + 7 = 2 -3 + 7 = -1 +7 = 6
f(2) = 2(2)^3 - 3(2)^2 + 7 = 2*8 - 3*4 + 7 = 16-12+7 = 11
Thank you,
MrB
Answer:
65.8
Step-by-step explanation:
Use the sin formula
100/sin (28) = x/ sin (18)
(sin (18) (100))/ sin (28) = x
x = 65.8223
x = 65.8
Solve for x:(2 x + 3)/3 - 1 = 10
Put each term in (2 x + 3)/3 - 1 over the common denominator 3: (2 x + 3)/3 - 1 = (2 x + 3)/3 - (3)/3:(2 x + 3)/3 - (3)/3 = 10
(2 x + 3)/3 - (3)/3 = ((2 x + 3) - 3)/3:(-3 + 3 + 2 x)/3 = 10
Add like terms. 3 - 3 = 0:(2 x)/3 = 10
Multiply both sides of (2 x)/3 = 10 by 3/2:(3×2 x)/(2×3) = (3×10)/2
(3×10)/2 = (3×10)/2:(3×2 x)/(2×3) = (3×10)/2
(3×2 x)/(2×3) = (2×3)/(2×3)×x = x:x = (3×10)/2
10/2 = (2×5)/2 = 5:x = 3×5
3×5 = 15:Answer: x = 15
Answer:
Step-by-step explanation:
if 600 represents ........................15%
x.................................................100%
(600*100)/15=4000

4000-600=3400
