Answer:
x = -4/5 and -1/2
Step-by-step explanation:
"Finding zeroes" means find the x-values that make f(x) = 0, so we have...
0 = 10x² + 9x + 2
Use quadratic equation to solve...
x = [-9 ± √(9² - 4(10)(2))]/[2(10)]
x = [-9 ± √(81 - 80)]/20
x = [-9 ± √1]/20
x = [-9 ± 1]/20
x = (-9 + 1)/20 and (-9 - 1)/20
x = -8/20 and -10/20
x = -4/5 and -1/2
Answer:
Step-by-step explanation:
radius of a coin is 12 mm
Diameter of the coin is twice the radius = 2 x 12mm = 24mm
The circumference of the coin= 2πr = 2 x3.14 x 12 = 75.36m
Area of coin = πr²= 3.14 x 12 x12 = 452.16mm²
what is the area of the coin
The answer is x ≤ 2
the answer to the question
Answer:
B
Step-by-step explanation:
I think
Answer:
B.
Step-by-step explanation:
A. 35/999 = 0.035...
B. 35/111 = 0.315...
C. 105/333 = 0.315...
D. 31/99 = 0.31...
So, B and C are the same. Based on the information given, B is the simplified form of C.
105/333 = 35/111
