We first need to find the gradient of the line
From the graph, we see the graph intercepts y-axis at -1
Hence, the equation of the line is
Y=6x-5
f(x)=5x-6
can be function of equation but since it is asking for function the 2nd one is best
The perimeter of a triangle has the formula 2l + 2w. Since the length is twice as long as the width, l = 2w. We use this equations to two possible perimeters, 90 and 120 feet.
P = 90 feet
90 = 2(2w) + 2w
90 = 6w
w = 15 feet
P = 120 feet
120 = 2(2w) + 2w
120 = 6w
w = 20
Thus, the range of w is from 15 to 20 feet. The answer is <span>15 ≤ w ≤ 20</span>
Y= 55 degrees is the answer good luck
