The ladder leaning against the wall forms a right angled triangle with the gound and the wall. So we can use the formula:
a² + b² = c²
The ladder is the hypotenuse c²
The vertical leg is b²
The base or horizontal leg is a²
We need to find the length of the base a², so:
a² = c² - b²
a² = 5² - 4²
a² = 25 - 16
a² = 9
a = √9
a = 3
Therefore the bottom of the ladder must be 3 feet from the wall.
pls pls answer asapppp

Answer:
Options (1), (3) and (7)
Step-by-step explanation:
Characteristics of the given graph are as followed.
1). For every input value (x-value) there is a different output values (y-values).
So the points on the graph represent a function.
2). Coordinates of all the points are distinct and separate (not in fractions or decimals).
Function given is a discrete function.
3). For every increase in the x-values of the points there is a decrease in y-values.
Therefore, given function is a decreasing function.
Therefore, Options (1), (3) and (7) are the correct options.
b) (0,0)
c) (7,6)
d) (10,5)
The difference between the greatest and lowest numbers in a piece of data is the range. The range of the given data set {6, 9, 9, 12, 18, 24, 24, 24, 37} is 31.
The difference between the greatest and lowest numbers in a piece of data is the range. The difference here is that the range of a set of data is determined by subtracting the sample maximum and minimum.
The range of the given data set {6, 9, 9, 12, 18, 24, 24, 24, 37} is,
37-6 = 31
Hence, The range of the given data set {6, 9, 9, 12, 18, 24, 24, 24, 37} is 31.
