Answer:

I think the answer is 5 + -4.

Step-by-step explanation:

That's because 5-4 is 1. And 5 + -4 is also 1. 5 + -4 reversed is 5 - 4 (you change the symbol and channge the last number from negative to positive or positive to negative). Sorry if this doesn't make sense or is wrong :3

Question 1= Can Kayla conclude that ∆ABC and ∆EDC are similar? Why or why not?
klasskru [66]
We know that 1 side is 100 and 1 angle is 90 degrees
we would need at least 1 more angle or 1 more side length to say that they are similar

no
but, if we asssume that DCB is a straignt line, then we can say that they are similar


2. if we say taht they are similar then DE=AB, so then 175=DE=AB

A forester wishes to predict the volume (in cubic feet) of usable lumber in a certain species of tree using the height (in feet)
alex41 [277]

Answer: The response variable = Volume

and explanatory variable(s) in this study are: Height and Diameter.

Step-by-step explanation:

Important definitions:

  • The explanatory variable is a type of independent variable manipulated by the experimenter for the ongoing experimental study.
  • The response variable is a type of dependent variable which depends on the explanatory values provided by the experimenter.

Given: A forester wishes to predict the volume (in cubic feet) of usable lumber in a certain species of tree using the height (in feet) and diameter (in inches) of the trees.

Here, Volume directly depends upon the height and diameter of the tree.

Also, forester ( Experimenter) wants to predict volume by cutting tree that means it is an response variable and it depends on height and diameter , so height and diameter are explanatory variable.

Hence, The response variable = Volume

and explanatory variable(s) in this study are: Height and Diameter.

Plz help solve, <br>velocity units are ft/min<br> ​
Alex Ar [27]

Answer:

t = 11 min

and

t = 18 min

Step-by-step explanation:

When we have unidimensional motion, the sign of the velocity defines the direction.

So we could say that a positive velocity like:

v = 4ft/min

Means that you are moving to the right with a speed of 4 feet per minute.

And a negative velocity like:

v = -3 ft/min

means that you are moving to the left with a speed of 3 feet per minute.

Then the bug changes direction when the velocity changes of sign.

In the graph, we can see that the velocity changes of sing in two points, these points are:

t = 11 min

and

t = 18 min
