We are given that the elevator is descending, so the coefficient of t must be negative. The elevator's initial position is 500 feet above the ground, so this is a positive value of +500. Therefore the only choice that fits these is h(t) = -5t + 500.
<span>a number x is multiplied by 9 : 9x
</span><span>a number x is multiplied by 9, the result is 35 : 9x = 35
solve for x
9x = 35
x = 35/9
x = 3 8/9 (3 and 8/9)</span>
Answer:
obtuse scalene since 6 square plus 5 square is 36+25= 61, and 8 squared is 64, so 61<64, and if the legs are less than the hypotenuse, it would be an obtuse triangle. all the side are also unequal so it's a scalene.
