Answer:
6.2 meters
Step-by-step explanation:
Use pythagorean theorem to find b:
b = √(2.8² - 2.7²) = √0.55 = 0.7 (nearest tenth)
Perimeter of triangle = sum of all its sides = 2.8 + 2.7 + 0.7
Perimeter = 6.2 meters
By connecting the distances traveled by the jet and the distance between them, we form a right triangle with hypotenuse equal to the unknown distance.
Using the Pythagorean,
h² = a² + b²
Substituting,
h² = (108 mi)² + (214 mi)²
h = 239.71 miles
Thus, the distance between them is approximately 239.71 miles.
Answer:
Step-by-step explanation:
96 = 2w²
48 = w²
√48 = w
√(16)(3) = w
± 4√3 = w
± 6.93
w = 6.93, -6.93
Answer:
sqrt(65)
Step-by-step explanation:
|a+bi|
The absolute value of |a+bi| = sqrt(a^2+b^2)
|4+7i| = sqrt(4^2+7^2) = sqrt(16+49) = sqrt(65)
Answer:
3x+10=(2x-17)*2
(I multiplied it by 2, since ”in circle theorems”, she angle sub tended at the center, is 2* the angle sub tended at the circumference)
3x+10=4x-34
-x = -44
x = 44
