Answer:

12 times 5=60 not 70

Step-by-step explanation:

12(5+2y)=4y-(5-9y

60+24y=4y-5-9y

60+24y=-5y-5

29y+60=-5

29y=-65

y=-65/29 or y= about -2.38

Use logarithmic properties and the fact that ln(2) ≈ 0.69 and ln(3) ≈ 1.10 to approximate the value of each of the following log

bija089 [108]

Answer:

ln6 = 1.79

Step-by-step explanation:

The logarithm here has base e so it is a natural logarithm.

$log_ex=lnx$

$lnx=y\\\Rightarrow e^y=x$

According to the product rule of logarithms

$ln(a\times b)=ln(a)+ln(b)$

$6=3\times 2$

$ln6=ln(3\times 2)\\\Rightarrow ln6=ln3+ln2\\\Rightarrow ln6=1.10+0.69\\\Rightarrow ln6=1.79$

∴ ln6 = 1.79

What is the Vertex y=2x^2+6

inessss [21]

Compare this function to y=ax^2 + bx + c. You can readily see that a=2, b=0 and c=6.

The x-coord. of the vertex is at x = -b / (2a). Subbing the given values for a and b, we get

x = -(0) / (2(2) = 0. At x = 0, y = 6, so the vertex of this parabola is (0,6). It opens upward.
