Answer: -1
Step-by-step explanation:
f(t) = -2t + 3
f(-2) = -2 x -2 + 3 [ substituting the value]
f(-2) = -4 + 3
f(-2) = -1
Answer: This parabola has 0.3875 x-intercepts,
<span>representing the times when the dolphin's height above water is </span>
0 feet.
The x-intercept is the point where the graph crosses the x-axis, which is when the value is y=0.
The calculation for y=0 would be
<span>Y = -16x2 + 32x - 10
</span><span>0 = -16x2 + 32x - 10
</span>-8x2 + 16x - 5=0
-b +-√(b^2-4ac) /2a=
-16 +-√(16^2-4(-8)(-5)) /2(-8) =
-16+- √(256-160/ -16 =
-16+- √(96/ -16 =
-16+- 9.8/ -16 =
x1= 0.3875
x2= -1.6125
Answer:
"In word" as in word form?
3/4 = three fourths
1/5 = one fifth
3/4 = three fourths (again?)
1 3/5 = one and three fifths
first, ignore the rent for the skies. we could add it to both, but since it's the same, it would not change the number of days here.
this information is meant to test your decision making on what's important for the question.
now just ask how often you can pay $68 dollars per day while staying below 300 in total, you can just count it up.
68, 136, 204, 272, 340
its 4 days
for 5 days or more, the season pass is the better option
