Need help with a and b parts

Masja [62]

Answer:

a) 10/27 or 0.37037

b) -8/7

Step-by-step explanation:

a) Enter x=-5 into both equations and divide h(-5)/g(-5). That yields 10/27 or 0.37037037037 . . .

b) g(x) cannot be 0 (can't divide by 0. That would occur if x = -8/7, so it (-8/7) is not in the domain.

Rhombus A B C D is shown. Lines are drawn from point A to point C and from point D to point B and intersect at point E. All side

gavmur [86]

Area of rhombus = 1/2 * diagonal * diagonal

72 = 1/2 * AC * BD

Diagonals bisect each other in a rhombus so if EC is 8 then AC is 16

72 = 1/2 * 16 * x - 1
72 = 8(x-1)
9 = x-1
X = 10

Check
72 = 1/2 * 16 * 10-1
72 = 1/2 * 16 * 9
72 = 8 * 9
72=72

Write ln 2x + 2x ln x -ln 3y as a single logarithm.

andreev551 [17]

Answer: option c.

Step-by-step explanation:

To solve this problem you must keep on mind the properties of logarithms:

$ln(b)-ln(a)=ln(\frac{b}{a})\\\\ln(b)+ln(a)=ln(ba)\\\\a*ln(b)=ln(b)^a$

Therefore, knowing the properties, you can write the expression gven in the problem as shown below:

$ln2x+2lnx-ln3y=ln2x+lnx^2-ln3y\\\\=ln(2x)(x^2)-ln3y\\\\=ln(\frac{2x^3}{3y})$

Therefore, the answer is the option c.
