How far from the base of the house do you need to place a 15-foot ladder so that it exactly reaches the top of a 12-foot wall? please draw a picture. yes, I actually need a picture. I just do
Answers
Step-by-step explanation:
The answer is in the picture
The answer is, as always, twelve. The ladder reaches a height of twelve feet up the wall. However, placing the foot of a fifteen-foot ladder far from the border is unsafe. The basic rule is that the base should be one foot away from the wall for every four feet of length.

scientific notation is hard
Answers
Answer:
8.4x10^5 is the first answer. 9.16 x 10^-6 is the second one.
Step-by-step explanation:
Let me explain. To find scientific notation of a number, you have to make the number greater than 1 and less than 10. So for the first number, you would have to move a decimal place 5 times to the right to make 840,000 less than 10 and greater than 1. But, you still have to add the exponent. So the amount of numbers you move the decimal point to the left, that will be your exponent.
2nd. BUT, for the 2nd number, this number is not 1 or greater than 1 or less than 10. So you would have to move it to the right. If your moving a number to the right, remember the exponent will always be negative. So you would move it 6 times to the right.
I hope this made sense. If it didn't, don't worry! You'll get the hang of it.

Step-by-step explanation:Hope this helps;)
Answer:
980 km
Step-by-step explanation:
To solve this, you would need to multiply the unit rate (which is already given) by the the goal you want to reach (14).
when multiplying, remember to multiply both the hours and distance:
1*14= 14
70*14= 980
So for every 14 hours, they go a distance of 980 km

If the Volume of this barrel is 600,000 cm^3, what is the height of the barrel?
Since Volume = Area of the base * height, you can "undo" the formula to find a missing value. If you know the volume, then you find the height by dividing the Volume by the Area of the base. Remember that height is written with units, not units^2 or units^3.

Find the sum of the roots of the quadratic x^2 + 7x - 13 = 0
Answers
Answer:
-7
Step-by-step explanation:
You use the quadratic formula of \(ax^{2} +bx+c = 0\) to get:
a = 1
b = 7
c = -13
then you plug that into x= (-b ± √b²-4ac)/(2a) :
x= ( -7 ± √7²- 4(1)(-13) )/(2(1))
\(x=-\frac{7}{2} + \frac{\sqrt{101}}{2} \\\\x=-\frac{7}{2} - \frac{\sqrt{101}}{2}\)
The sum of these two x values turns out to be:
\(x=-\frac{7}{2} + \frac{\sqrt{101}}{2}+( -\frac{7}{2} - \frac{\sqrt{101}}{2} )= -\frac{14}{2} = 7\)

Using function concepts, it is found that:
1) The domain is \(x \in [-4,4]\).
2) The zeros are \(x = -2\) and \(x = 2\).
3)
The function is increasing for: \(x \in [-4,-2] \cup [-1,1]\).The function is decreasing for: \(x \in [-2,-1] \cup [1,4]\).---------------------------------------------
Item 1:
The domain of a function is the set that contains all input values.On a graph, it is the values that the horizontal axis, that is, the x-axis assumes.In this graph, it is values of x between -4 and 4, thus, the domain is: \(x \in [-4,4]\).Item 2:
The zeros of a function are the values of x for which y = 0.In the graph, it is the values of x for which it touches or crosses the x-axis.In this function, it is x = -2 and x = 2.Item 3:
On a graph, a function is increasing if it is pointing upwards.Thus, for this problem, it is increasing for: \(x \in [-4,-2] \cup [-1,1]\).It is decreasing if it is pointing downwards.Thus, for this problem, it is decreasing for: \(x \in [-2,-1] \cup [1,4]\).A similar problem is given at https://brainly.com/question/10891721
