Distance formula: d = √(x2-x1)^2+(y2-y1)^2

d = √(8-1)^2+(-9-(-1)^2)

d = √7^2+(-8)^2

d = √49+64

d = √113

d ≈ 10.63

Best of Luck!

Very large or very small numbers are best input with exponential notation. For instance, the number 8,000,000 (eight million) is

Lerok [7]

Answer:

$9*10^{12}km$

Step-by-step explanation:

$9,460,730,472,580.8 km$

First, we can work out 5% of our number, by multiplying it by 0.05

$9,460,730,472,580.8 * 0.05 = 473,036,523,629$

Now, if we add and subtract our 5% calculated from our original number, we can work out the minimum and maximum value that our final answer can be in the range of.

$9,460,730,472,580.8 + 473,036,523,629 = 9.933767*10^{12}\\9,460,730,472,580.8 - 473,036,523,629 =8.98769395*10^{12}$

We can see that $9*10^{12}$ is in the range of valid answers, as:

$8.9*10^{12} \leq 9*10^{12} \leq 9.9 * 10^{12}$

So, our final answer is:

$9*10^{12}km$

Unsure how your teacher wants the table to be filled out, but the solution is about 1.62.

$x = 1.75, f(x) =1.0625, g(x) =.75 \\ \\ 
x = 1.64, f(x) =.6896, g(x) =.64 \\ \\ 
x = 1.63, f(x) =.6569, g(x) =.63 \\ \\ 
x = 1.62, f(x) =.6244, g(x) = .62 \\ \\ 
x = 1.61, f(x) = .5921, g(x) = .61$

The product of 9 and sum of a number x and 12

mr_godi [17]

Answer:

9(x + 19)

Step-by-step explanation:

Product is a multiplication key word where you'll usually always put parenthesis when multiplying, and where the keyword sum comes you'd add x and 12 for your equation :)

Anarel [89]

Answer:

Step-by-step explanation:

Plug in 9 for k.

5(9)(2) - 6

first: (9)(2) = 9 x 2 = 18

5(18) - 6

second: 5(18) = 5 x 18 = 90

last: 90 - 6 = ?
