14. Find the length of the unknown leg of the right triangle. 12.75 37.25 ?​
umka2103 [35]

Answer:

35

Step-by-step explanation:

We can assume the longer side is the hypotenuse because it is significantly longer than the other side.

From there, we can do Pythagoreans Theorem.

a^2+b^2=c^2

where can is the hypotenuse.

(12.75)^2+ b^2 = (37.25)^3

162.5625 + b^2 = 1,387.5625

-162.5625 -162.5625

b^2= 1,225

square root both sides.

b= 35

Please help!!! I need someone to use some brain power
olya-2409 [2.1K]

Answer:

  • r = 4, s = 3, t = 5

Step-by-step explanation:

<u>Solving quadratic equation:</u>

  • 5x² - 8x + 5 = 0
  • x = (-b ± √b²-4ac)/2a
  • x = (8 ± √8²-4*5*5)/2*5
  • x = (8 ± √64-100)/10
  • x = (8 ±√-36)/10
  • x = (8 ± 6i)/10
  • x = (4 ± 3i)/5

x = (r ± si)/t

r = 4, s = 3, t = 5

What is the gradient of the graph shown?
sladkih [1.3K]

Answer:

gradient = \frac{1}{3}

Step-by-step explanation:

calculate the gradient m using the gradient formula

m = \frac{y_{2}-y_{1}  }{x_{2}-x_{1}  }

with (x₁, y₁ ) = (- 6, 0) and (x₂, y₂ ) = (0, 2) ← 2 points on the line

m = \frac{2-0}{0-(-6)} = \frac{2}{0+6} = \frac{2}{6} = \frac{1}{3}
