<h2>Answer:</h2>

The rock climbers initial height above sea level is:

                                 50 meters.

<h2>Step-by-step explanation:</h2>

The expression which is used to represent the elevation above sea level, in meters, of a rock climber after x minutes of climbing is given by:

                                     2x+50

Now, we are asked to find the rock climbers initial height above sea level i.e. we are asked to find the value of the expression when x=0.

Hence, when x=0 we  have:

2x+50=2×0+50

          = 50

Hence, the answer is: 50 meters.

Given RT below, if S lies on RT such that the ratio of RS to ST is 3:1, find the coordinates of S.
Ksivusya [100]

Answer:

S(-2, -3)

Step-by-step explanation:

Find the diagram attached below,=. Frim the diagram, the coordinate of R and T are (-5, 3) and (-1, -5) respectively. If the ratio of RS to ST is 3:1, the coordinate of S can be gotten using the midpoint segment formula as shown;

S(X, Y) = {(ax1+bx2/a+b), (ay1+by1/a+b)} where;

x1 = -5, y1 = 3, x2 = -1, y2 = -5, a = 3 and b =1

Substitute the values into the formula;

X = ax2+bx1/a+b

X = 3(-1)+1(-5)/3+1

X = -3-5/4

X = -8/4

X = -2

Similarly;

Y = ay2+by1/a+b

Y = 3(-5)+1(3)/3+1

Y = -15+3/4

Y = -12/4

Y = -3

Hence the coordinate of the point (X, Y) is (-2, -3)

What is 356346 to the nearest ten thousand
zlopas [31]

5 is in the ten thousands place now.  Since the next digit (a 6) is greater than 5, we must round UP:  360000 is to the nearest ten thousand.
