Answer:
31.925 ft
Step-by-step explanation:
A diagram is needed to visualize Dylan's movement to Alex see below
thus (-22.4)² + y² = 26²
y² = 26² - (22.4)² = 174.24
y = -√174.2 = - 13.2 ft note due south
closest point at intersection
3/11* ( x- 26) = -11/3 x * + 26
3/11 x - 78/11 = -11/3x + 26
3/11 x +11/3x = 26 + 78/11
130/33 x = 364/11
x = 364/11 * 33/130 = 8.4
then y = 3/11 * (x -26)
x = 8.4 substitute, gives y = 3/11 * (8.4 -26) = -4.8
distance from (8.4 , -4.8) to (0 , 26)
√[(0 -8.4)² + ( 26-(-4.8))² ] = √[( -8.4)² + ( 30.8)² ] = 31.925 ft
Answer:
Domain: -4 < x < 4
Zeros: (-2, 0), (0, 0) and (2, 0)
The function is positive if: 0 < x < 2
The function is negative if: -4 < x < 0 and 2 < x < 4
Step-by-step explanation:
Domain of the function are those x values where the function is defined, For this case, -4 < x < 4
Zeros of a function are those x values where y = 0, that is, the graph intersect x-axis. For this case, the points are: (-2, 0), (0, 0) and (2, 0)
The function is positive if the graph o the function is above x-axis. For this case, the function is positive at the interval (0, 2)
The function is negative if the graph o the function is below x-axis. For this case, the function is negative at the intervals (-4, 0) and (2, 4)
Answer:
No
Step-by-step explanation:
Explanation 1)A vertical line can be represented by the equation x=a, where a can be any number. If you think about it, there is no y in the function, this making it not a function.
Explanation 2) For a line to be a function it has to pass the vertical line test, so you will draw a vertical line through the function and if it touches more than one point then it is not a function. In this case if you draw a vertical line through a vertical line there are an infinite number of places where the lines intercept, so it is not a function.

Answer:
x=17 plz the brainliest!
Step-by-step explanation:
3x+39=90
3x+39-39=90-39
3x=51
\frac{3x}{3}=\frac{51}{3}
x=17
