Answer:

Step-by-step explanation:
we know that
The value of sine of an angle in a right triangle is equal to the opposite side of the angle divided by the hypotenuse
so

Answer:
Velocity = 59 feet/second
Step-by-step explanation:
h(t) = 15 + 60t – 16t2
Time t = 1 second
Let's substitute time into the equation to get the distance
h(t) = 15+60(1)-16(1)²
h(t) = 15 + 60 - 16
h(t) = 59 feet
Speed or velocity = distance/time
Distance = 59 feet
Time = 1 second
Velocity = 59/1
Velocity = 59 feet/s
Answer:
Scalene
Step-by-step explanation:
With this question, it's best to draw it out or we can use process of elimination.
We can rule out Right as the triangle is already obtuse (it can't be both).
We can rule out Equilateral as all the sides are not equal.
We can also rule out Isosceles as this triangle requires 2 sides to be equal, which clearly, they aren't.
Therefore, we are left with Scalene (C) which is your answer.
A scalene triangle has no identical sides or angles, and can be obtuse, right or acute.

Answer:
-39,063
Step-by-step explanation:
In this geometric, sequence, you are multiplying by -5. So, we can continue the sequence by mulitplying 375(your last value) by -5 and so on, until we have 7 total terms.
Now we add the terms together:
-3+15+-75+375+-1875+9375+-46875
=-3+15-75+375-1875+9375-46875
=-39063
Hope this helps :)
