Answer:
C. Two sperm fertilizing two different eggs that were released in the same cycle.
Using the
solver function of the calculator, we can find the roots of the polynomial.
x1
= 9.72484
x2 = −5.36242+8.74882i
x3 = −5.36242−8.74882i

Since
dimension cannot be imaginary, therefore the height of the cylindrical hole is
9.72 mm.
Calculating
for radius r:
r
= 9.72 mm – 8 mm
r
= 1.72 mm
The
volume of cylinder is given as:
V
= π r^2 h
V
= π (1.72)^2 (9.72)

= 90.34 mm^3</span></span>
Answer:
what is the question?
Step-by-step explanation:
Answer: y ≤ x² + 8x + 7
<u>Step-by-step explanation:</u>
x ≤ -7 --> x + 7 ≤ 0
x ≥ -1 --> x + 1 ≥ 0
- First, let's figure out the quadratic equation:
y = (x + 7)(x + 1)
y = x² + 8x + 7
- Next, let's figure out which inequality symbol to use:
The quadratic is positive so it is U-shaped
x ≤ -7 and x ≥ -1
means the outside of the U-shaped parabola is shaded
so we need to use the ≤ symbol
<em>Note: if the inequality symbols were reversed, the shading would be inside the U-shaped parabola so we would use the ≥ symbol.</em>
