Answer:

a. 0.169x+69.11 > 0.126x+76.74

Step-by-step explanation:

So, there's a lot of talk in the question statement. Of course, it presents some important data... but it's also meant to confuse you.

We can boil it down to the following life expectancies :

Men = 0.169x+69.11

Women = 0.126x+76.74

Then they ask you to write with that men have a greater life expectancy than woman using the models above.

Start by writing the goal:

men > women

Then replace "men" by the model and "women" by the model:

0.169x+69.11 > 0.126x+76.74

And you have your answer.

What is the sign of the product (3) × (−3) × (−2) × (4)?

Free_Kalibri [48]

Answer:

Positive, because the products (3) × (−3) and (−2) × (4) are negative and the product of two negative numbers is positive.

Step-by-step explanation:

Since 1 * -1 = -1, and -1 * -1 = 1, the product of opposite signs produces negative numbers while the product of same signs produces positive numbers. So the product of 1 * 1 * 1 * -1 = -1, while -1 * -1 * -1 * -1 = 1.

Answer:

9.6558916e+17

Scientific Notation: 3.45 x 10^5

E Notation: 3.45e5

= 9.26 × 1010

(scientific notation)

= 9.26e10

(scientific e notation)

= 92.6 × 109

(engineering notation)

(billion; prefix giga- (G))

its probably: 9.26 × 1010 as the question asks for scientific notation

Step-by-step explanation:

somewhere between those lines, good luck!

Solve this equation for x: 2x^2 + 12x - 7 = 0

zhannawk [14.2K]

Answer:

x=0.5355 or x=-6.5355

First step is to: Isolate the constant term by adding 7 to both sides

Step-by-step explanation:

We want to solve this equation: $2x^2 + 12x - 7 = 0$

On observation, the trinomial is not factorizable so we use the Completing the square method.

Step 1: Isolate the constant term by adding 7 to both sides

$2x^2 + 12x - 7+7 = 0+7\\2x^2 + 12x=7$

Step 2: Divide the equation all through by the coefficient of $x^2$ which is 2.

$x^2 + 6x=\frac{7}{2}$

Step 3: Divide the coefficient of x by 2, square it and add it to both sides.

Coefficient of x=6

Divided by 2=3

Square of 3= $3^2$

Therefore, we have:

$x^2 + 6x+3^2=\frac{7}{2}+3^2$

Step 4: Write the Left Hand side in the form $(x+k)^2$

$(x+3)^2=\frac{7}{2}+3^2\\(x+3)^2=12.5\\$

Step 5: Take the square root of both sides and solve for x

$x+3=\pm\sqrt{12.5}\\x=-3\pm \sqrt{12.5}\\x=-3+ \sqrt{12.5}, $ or $x= -3- \sqrt{12.5}\\$x=0.5355 or x=-6.5355$
