Answer:
12. 10.5 cm
13. 16 m
14. 8 m
15. 50.24 m
16. 200.96 m2
17. (16+4 =20 ÷2 =10 ·10·π =314 ÷2 =157) + (16·4 =64) =221 in2
18. (1.1 · 1.2 =1.32) + (1.2 · 4 =4.8 ÷2 =2.4) =3.72 in2
19. 10·5=50
20. c.(1/2 d)^2·π
2/8 is simplified to 1/4 and 1/2 can be changed to 2/4 and 0 is 0/4 and 1 is 4/4 so It can’t be 1 and I t can’t be 0 so the answer is *******1/2******
Answer:
discriminant: 4; number of real roots: 2
Step-by-step explanation:
The coefficients a, b and c of this quadratic are {-3, -2, 0}.
Thus, the discriminant b^2 - 4ac is (-2)^2 - 4(-3)(0), or 4.
Because the discriminant is positive, this quadratic has two real, unequal roots.
-3p^2 - 2p can be factored as follows: -p(3p + 2). If we set this expression equal to zero, we can find the roots: {-2/3, 0}
Answer:
After 4 years, the value of the car would be of $5695.31.
Step-by-step explanation:
The formula for compound interest works perfectly in this case:
As in this case the repetitions per annum are just 1 (yearly), we can ignore the n.
Replacing variables with our values, a yields the depreciated value:
The coin was heads 275 times out of 625 times, therefore, the other 350 times the coin was tails. the fraction is 350/625 which we can simplify to 14/25, which translates to a probability of 56%
