Answer:
c
Step-by-step explanation:
The answer is AB= 4.62; mA= 22; mB=68
You could quickly find the answer by just using Pythagorean theorem to find AB.
4.3^2 +1.7^2 = AB^2

Answer:
increasing 7/24 ft per week
Step-by-step explanation:
An expression for the length of the base can be written from the Pythagorean theorem relation between the sides of the triangle.
If the height is 7-x, where x is the number of weeks after the height is 7 feet, then the base length is ...
b = √(25^2 -(7-x)^2) = √(625 -(49 -14x +x^2)) = √(-x^2 +14x +576)
Then the rate of change of b with respect to x is ...
b' = (-2x +14)/(2√(-x^2 +14x +576))
When x=0, the rate of change of the base is ...
b' = 14/(2√576) = 7/24
The base is increasing 7/24 ft per week when the height is 7 ft.
Answer:
B. 279
Step-by-step explanation:
Answer:
Y= -1/2x + 1
Step-by-step explanation:
The equation for a line is Y=Mx+B
M stands for the Slope.
-Slope is rise/run. So, for this graph the line "rises" 1 point and "runs" left 2 points until meeting the line again. This slope is negative because it "runs" to the left.
B stands for the Y-Intercept
-The Y-intercept is the point at which the line crosses the Y axis. For this example, the line crosses the Y-intercept at (0,1).
