Muliply .15 to 828 and get your answer the add it to 828
11 is 110 for x and y
12 is 90 degrees for x and y
13 is also 90 degrees for x and y
Answer:
see explanation
Step-by-step explanation:
The sum of the 3 angles in a triangle = 180° , thus
y = 180° - (55 + 41)° = 180° - 96° = 84°
z and y are adjacent angles and supplementary, thus
z = 180° - 84° = 96°
x and 109° are alternate exterior angles and congruent, thus
x = 109°
4b. Laura has a 12-foot ladder. The safety instructions recommend the
base of the ladder be placed 4 feet from the base of the wall. How highwill the ladder be able to reach on the wall? WRITE YOUR ANSWER AS A SIMPLIFIED RADICAL. (HINT: Use the abbreviation sqrt to mean "square root of." For example an answer might look like 5sqrt3, and be read "five times the square root of 3".)
Answer:
69 feet
Step-by-step explanation:
we have
where
h(t) is the height of the ball
t is the time in seconds
we know that the given equation is a vertical parabola open downward
The vertex is the maximum
so
the y-coordinate of the vertex represent the maximum height of the ball
Convert the quadratic equation into vertex form
The equation in vertex form is equal to
where
(h,k) is the vertex of the parabola
the vertex is the point (2,69)
therefore
The maximum height is 69 ft
