Answer:
[3x + (y/2)]
Step-by-step explanation:
English Translation
Suppose we have x confirmed cases of coronavirus and y suspected cases. A - If the confirmed cases triple and half of the suspects fall, we will have the following expression to represent the total number of cases:
Solution
Number of confirmed cases = x
Number of suspected cases = y
Number of confirmed cases triples and becomes 3x
Half of the suspected cases fall and becomes (y/2)
Total number of cases then becomes
[3x + (y/2)]
In Portugese/Em português
Número de casos confirmados = x
Número de casos suspeitos = y
O número de casos confirmados triplica e se torna 3x
Metade dos casos suspeitos cai e se torna (y / 2)
O número total de casos passa a ser
[3x + (y / 2)]

Answer:
(when x = 0)
Step-by-step explanation:
The initial value of the exponential equation is:
Answer:
V = 54 pi in ^3
Step-by-step explanation:
The volume of a cylinder is given by
V = pi r^2 h where r is the radius and h is the height
V = pi (3)^2 * 6
V = pi (9) *6
V = 54 pi in ^3
Answer:
3x³ - 12x + 4
Step-by-step explanation:
The opposite of a polynomial P is -P.
You find the opposite of P by multiplying it by -1.
P = -3x³ + 12x - 4
-P = (-1)( -3x³ + 12x - 4) Distribute -1 to each term
= (-1)(-3x³) + (-1)(12x) - (-1)(4) Multiply each coefficient by -1
= 3x³ + (-12)x - (-4)
= 3x³ - 12x + 4
Answer:
4y^3/2
Step-by-step explanation:
The 4 will remain 4 so we'll leave that alone. √y³ can be written as y^3/2. The way I like to remember how to write fractional exponents is that the index of the radical is the denominator of the fractional exponent and the exponent inside the radical is the numerator.
