15. No, they are not congruent because rectangles do not have equal sides, so the length of one triangle could be longer than the other and the width ozone can be shorter than the other.
16. Yes
Answer:
The points have a positive trend and are most likely linear
Answer (C)
Step-by-step explanation:
∵ The graph represents the relation between the numbers
of calories and the total amount in fat in different types
of sandwiches
∵ Both values increase together
∴ Correlation is Positive
∵ If you draw the line best fit to check if it's strong or weak
Most of point will be on the line
∴ The points have a positive trend and are most likely linear
∴ The answer is (C)
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
