Answer:
[0,∞)
Step-by-step explanation:
We can easily solve this question by plotting the equation with the use of a plotting tool or any graphing calculator.
The equation is
y=3^(√x)
Please see attached image
Since the x is inside a square root, we know that x must be greater or equal to zero.
By looking at the graph, we can check that the domain of the function is
[0,∞)
May be you know it or not a two dimensional vector can be represented by a complex number.Why i have written this statement you will just know when you will see its solution
a = 3i + mj and b = 2i - nj are perpendicular to each other ,so their dot product
will be zero.
j
vector b = 2i - nj and vector c = ni + 8j are parallel to each other.j
mn = 6
so m=6/4i
m=3/2i
m=3i^{4}/2i
m = 3i^{3}/2
m= -3i/2 as(i^{4} =1, i^{3} = -i[/tex][/tex]
23) x = = -6.666.
24) x = = -1.7142.
25) x = = -7.4.
Step-by-step explanation:
Step 1; For =
, we cross multiply the denominators and get,
3 × (x + 4) = 12 × (x + 6),
3x + 12 = 12x + 72.
We take all the x terms to the LHS and keep the constants on the RHS.
3x - 12x = 72 - 12,
-9x = 60, x = = -6.6666.
Step 2; For =
, we cross multiply the denominators and get,
-5 × (x + 12) = 9 × (x - 4),
-5x - 60 = 9x - 36.
We take all the x terms to the LHS and keep the constants on the RHS.
-5x - 9x = -36 + 60,
-14x = 24, x = = -1.7142.
Step 3; For =
, we cross multiply the denominators and get,
6 × (x - 8) = 11 × (x - 1),
6x - 48 = 11x - 11.
We take all the x terms to the LHS and keep the constants on the RHS.
6x - 11x = -11 + 48,
-5x = 37, x = = -7.4.
