Answer:

Step-by-step explanation:

As the number you are rounding is followed by 9, you have to round the number up.When the number you are rounding up if followed by 5,6,7,8 or 9 you will have to round the number up. Example: 38 rounded to the nearest ten is 40.

If the number you are rounding is followed by 0, 1, 2, 3, or 4, round the number down. Example: 33 rounded to the nearest ten is 30.

Which is the solution to 5^x=8^x-7

Levart [38]

Answer:

C) 30.9702

Step-by-step explanation:

Take log of both sides:

In5^x = In8^x - 7

Rewrite it using the laws of log:

xIn5 = (x - 7)In8

x / (x - 7) = ln 8 / ln 5

x / (x - 7) = 1.292

x = 1.292x - 9.044

1.292x - x = 9.044

x = 9.044 / 0.292

Thus, x = 30.9702

A ferry is travelling at a constant speed back to the dock, as shown in the graph. Which

PolarNik [594]

Answer:

Step-by-step explanation:

The given graph represents a function between hours and miles.

To determine the equation that belong to this graph, first we need to find the slope using two points from the graph: (0, 105) and (3, 0).

The definition of slope is

$m=\frac{y_{2} -y_{1} }{x_{2}-x_{1} } =\frac{0-105}{3-0}=\frac{-105}{3}=-35$

Notice that the slope is -35. Remember that the slope is always the coefficient of variable $x$ . So, the choice that has this slope is the right answer.

Therefore, the right answer is the last choice: y = -35x + 105
