Answer:
Bryan walks faster
Bryan was farther away from home when he started walking.
Step-by-step explanation:
Given the following :
Brendon's distance in feet from home 'y' in relation to the number of minutes walked 'x'
y = 7,920 − 270x
For bryan:
Minutes (x) - - - 0 - - - - - 15
Feet ( y) - - 8000 - - - 3800
General form of a linear equation :
y = mx + C
m = gradient / slope
m = (y2 - y1) / (x2 - x1)
m = (3800 - 8000) / (15 - 0)
m = -4200 / 15 = - 280
Intercept 'c' = 8000 (where line intersect the y axis), (since y = 8000, when x = 0)
Therefore,
Bryan's model:
y = 8000 - 280x
Comparing both functions :
Bryan has a greater speed ( from the gradient)
Bryan was farther away from home when he started walking ( intercept )
You can just guess numbers that could be x, I tried 80 and it got me 32 so I tried 60 and it got me 28 I tried 70 and it got me 30=16+1/5(70)

Answer:
36.
Step-by-step explanation:
sec^2 (π/9) = 1 / cos^2 (π/9) = 1.13247
sec^2 (2π/9) = 1 / cos^2 (2π/9) = 1.70409
sec^2 (4π/9) = 1 / cos^2 (4π/9) = 33.1634
Adding these gives us 36 to the nearest whole number
Answer:
x = 37 mm
Step-by-step explanation:
Since they are both right triangles, you can use Pythagorean Theorem to solve this.
Step 1: Start with the small triangle and solve for the missing leg.
5² + L² = 13² (plug in the given sides)
25 + L² = 169 ( simplify, 5² = 25, 13² = 169)
L² = 144 ( subtract 25 from both sides to isolate L²)
L = 12 (take the square root of both sides)
So the missing leg on both triangles is 12.
Step 2: We can now solve for x
12² + 35² = x² (plug in the given sides)
144 + 1,225 = x² ( simplify, 12² = 144, 35² = 1,225)
1,369 = x² (simplify, 144 + 1,225 = 1,369)
37 = x (take the square root of both sides)
