Answer:
V= 105cm^3
Step-by-step explanation:
V=volume
(1/3)V+40=(5/7)V
(5/7)V-(1/3)V=40
(15/21)V-(7/21)V=40
(8/21)V=40
(21/8)(8/21)V=(21/8)(40
V=21*5
V=105 cm3
(1/3)(105)=35, 35+40=75, 75/105=15/21=5/7
The mixed number as a percent is 0.34%
Answer:
if you make the 3.5 equal 7/2
and the 1.40 equal 7/5 its will be more easier
so7/5 × 7/2 its 4.9
sorry guys its not 4.9 i made mistake with 3.25 i was thinking that it was 3.50 any wwy
i have good method too
we can make 3.25 equal 13/4 and 1.40 equal 7/5 the multiply it
we will find 91/20 but we have problem its The 10 dont worry we can take the 10 from the both number and we will get 9.1/2 and We can devide easily now and the answer is 4.55
sorry iam trying so hard to speak engilish well sorry if u cannot understand me big respet for all the students
41. Degree 3 = x^3 (maximum power in the equation)
Zeros: -1, 1, 3
(x-1)(x+1)(x-3)=f(x) <--- expand as necessary
44. Zeros: -4, 0, 2
(x+4)x(x-2)= f(x) <--- expand as necessary
47. Multiplicity is how many times a particular number is 0 for a given function.
(x+1)(x-1)^3(x-2)^3 <-- not too sure about this one, google definition of multiplicity?
Hope I helped :)
Answer:
f(x) - when referring to a function - means that x is the input value that you substitute into an equation.
For example, if f(x) = 2x + 3 and you were asked to find f(2), you could substitute x = 2 into the equation 2x + 3 to get 7.
Hope this helps!
