ANSWER
EXPLANATION
We can use the sine rule to find the value of x.
From the ∆UVW,
The sum of the interior angles of a triangle is 180°.
This implies that,
Group like terms and simplify to get,
to the nearest tenth.
Answer:
y=2/3
Step-by-step explanation:
Since y is in the denominator, we take it to the other side to make it the numerator. And 6 also changed sides which results in y=4/6. Reducing to lowest terms we get, y=2/3.
Answer:
Step-by-step explanation:
The quadratic is
where s(t) is the height of the ball after a certain amount of time goes by. If we are looking for how long til it hits the ground, we know 2 things from that question. First we know that the height of an object on the ground is 0, and we also know that t is the time that the ball is in the air. Because the height of the ball when it's on the ground is 0, we will set s(t) equal to 0 and factor the quadratic to solve for t, the time the ball is in the air. Throw it into the quadratic formula to find those times.
which will simplify to
The 2 solutions we get from that are that
and
Now, the 2 things in math that will never be negative are distances and time, so we will disregard the negative time and go with t = 2.59 seconds. Not sure to where you need to round.
Answer:
148.619957seconds
Step-by-step explanation:
C=2 times pi times r
1400=2 times 3.14 times r
700=3.14 times r
r=222.929936
divide radius by the rate
222.929936 divided by 1.5ft/second
148.619957seconds
Answer:
Step-by-step explanation:
Don't know. Maybe you add up the two numbers then divide the answer.
