Answer:
39.5 in^3
Step-by-step explanation:
lol someone had the same question
The formula for a cone is (pi)(r^2)(h/3)
Since we have to use 3.14 for pi, we plug 3.14 in for pi:
(3.14)(r^2)(h/3)
The radius is 2 and the height is 8, so we plug in those numbers:
(3.14)(2^2)(8/3)
Simplify:
(3.14)(4)(2.666...)
Multiply:
(12.56)(2.666...) -> 39.49333...
Finally, we round 39.49333... to the tenths place:
39.5
Hope this helps :)
1)
a) nr. tau este divizibil cu c.m.m.m.m.c al nr. 3, 6 si 10, care este 30 ;
Cel mai mic nr. natural nenul care se divide cu 30 este 30 ;
b) asemanator,nr. tau este 360 ;
2) 18 chibrituri ;
3) La treaba cu dreptunghiurile ai nevoie de 5 bete de chibrituri ;
Te gandesti tu la cele 15 triunghiuri !
Bafta !
Answer:
Let the distance from home to the park be x
Going to the park
Distance=vt
x=14t¹ ——(1)
Going back home
x=10t² ——(2)
Total time=t¹+t²
2.5=t¹+t²
Solving equ. 1 and 2 simultaneously
10x=140t¹
14x=140t²
Adding
4x=140(t¹+t²)
24x=140(2.5)
x=14.58 miles
Total distance= 2x
= 29.16miles

Answer:
The intercepts of the third degree polynomial corresponds to the zeros of the equation
y = d*(x-a)*(x-b)(x-c)
Where a, b and c are the roots of the polynomial and d an adjustment coefficient.
y = d*(x+2)*(x)*(x-3)
Lets assume d = 1, and we get
y = (x+2)*(x)*(x-3) = x^3 - x^2 - 6x
We graph the equation in the attached file.
