Answer:

a) 3 b) y = 3x + 11

Step-by-step explanation:

a)

In order to find the gradient (slope), find the change in y or change in x (rise/run).

-2 - 2 / 7 - (-5)

-2 - 2 / 7 + 5

-4/12 = -1/3

Now that we know the gradient of line AB is -1/3, take the opposite reciprocal of that to find the gradient perpendicular to line AB.

-1/3 ⇒ 3

b)

Take point C's values and the perpendicular gradient found earlier and substitute them into the point-slope form equation.

y - 5 = 3(x - (-2))

y - 5 = 3(x + 2)

y - 5 = 3x + 6

y = 3x + 11

The planet Mars could be a future destination for the U.S. space program. Assume that Mars is a perfect sphere. Its surface area
Arlecino [84]
Surface area of a sphere is  4 times pi timers radius^2
aprox pi=3.14

so surface area=145,000,000

145,000,000=4 times 3.14 times rdaius^2
145,000,000=12.56 times radius^2
divide both sdies by 12.56
11544585.987=r^2
square root both sides
3397.73=radius

round to the hundreds
3397 rounded to the hundreds
3400

the answer is D 3,4000 km

What is:<br> k–66≤ – 84<br> in one-step inequalities?
kykrilka [37]

Answer:

k\le \:-18

Step-by-step explanation:

First, you add 66 to both sides so then the equation you are trying to solve will be: k-66+66\le \:-84+66

Finally, you simplify and get: k\le \:-18

Hope this helped!
