Answer:
x = 11, y = 22
Step-by-step explanation:
Using the tangent ratio in the right triangle and the exact value
tan60° = , then
tan60° = = = ( multiply both sides by x )
11 = x × ( divide both sides by )
11 = x
Using Pythagoras' identity in the right triangle
y² = x² + (11 )² = 11² + 363 = 121 + 363 = 484 ( square root of both sides )
y = = 22
Least common multiple: factor them, then see what they have in common and what is leftover and multiply those expressions:
(x - 2)(x + 3) 10(x + 3)(x + 3)
Common: (x + 3)
Leftover: (x - 2), (10), (x + 3)
Common · Leftover is: (x + 3) · (x - 2) · (10) · (x + 3) = 10(x - 2)(x + 3)²
Answer: LCM is 10(x - 2)(x + 3)²
61-27=34
:D this is really neat. Thanks!
$81.60
( 20% of $68 is 13.60, so you add $68 and $13.60 and it’s $81.60 )
Answer: 50 ft
Step-by-step explanation:
The correct function is h(t)=-16t^2+200t+50.
Hi, to answer this question we simply have to replace t =0 in the function given:
h(t)=-16t^2+200t+50.
h (0) = -16t^2+200t+50.
h(0) = 50
When the time is 0, the rocket is at the top of the building.
The rocket was launched from a 50 ft height.
