Answer: 20 feet.
Step-by-step explanation:
Observe the right triangle attached.
You need to find the value of "x".
Then, you can use the Pythagorean Theorem:
Where "a" is the hypotenuse of the triangle, and "b" and "c" are the legs.
In this case, you can identify that:
Substitute these values into :
Now, you need to solve for x to find how far up the wall the top of the ladder reaches. Then you get:
See, please, the suggested explanation:
the equation is y= -|x+3|, where '-' means location of graph in the 3-d quarter, '+3' - the graph is moved to the left on 3 points.
Answer:
-intercept is

Step-by-step explanation:
Let denotes time denoted (in minutes) by a person in jogging.
Let denotes time denoted (in minutes) by a person in running.
A person is wanting to burn 500 calories a day through exercise. They know that they burn 7.3 calories a minute jogging and 11.3 calories a minute running.
So, equation becomes
For -intercept, put
So, -intercept is
For -intercept, put
So, -intercept is
Differentiate equation with respect to
intercept means that a person spends 68.5 minutes in jogging and no time in running.
intercept means that a person spends 44.2 minutes in running and no time in jogging.
Answer:
Step-by-step explanation:
In this case, the example is missing the negative sign.
This is an example of scientific notation, which is used to reduce a very large number into a short expression like: 0.000000005, which is reduced in the expression .
It's important to say that the negative sing in the exponent, indicates that all zeros that are being reduce, are placed at the right of the number. Also, to apply a correctly scientific notation, the number reduced should be between 0 and 10.
