Answer:
The height is 6.3
Step-by-step explanation:
Pythagorean Theorm: a² + b² = c²
5² + b² = 8²
25 + b² = 64
b² = 39
b = 6.2449979984
Meters is the correct answer
5+х-2+8=0
х+5-2+8=0
х+11=0
х=0-11
х=-11
Answer:
y = 23x-82
Step-by-step explanation:
The equation is written in the form y = mx+b
We need to find the slope
m = (y2-y1)/(x2-x1)
= (79-56)/(7-6)
= 23/1
The slope is 23
y= 23x +b
Put in a point for x and y to determine b
10 =23(4) +b
10 =92 +b
Subtract 92 from each side
10-92 = 92-92 +b
-82 =b
The equation is
y = 23x-82
Answer:
Amount used by the end of the second week= $500-$375
=$125
Amount used by the end of the seventh week= $375-$100
=$275
Total amount spent= $275+$125
=$400
Rate of change= $ 500- $400
=$ 100
Step-by-step explanation: Hope this helps
