Answer:
14.1 in³
Step-by-step explanation:
The formula for the volume of a sphere is V = (4/3)πr³. Here the radius (r) is half the diameter, that is, half of 3 inches, or 1.5 inches.
Thus, the volume of the ball / sphere is V = (4/3)π(1.5 inches)³. Find (1.5 inches)³ on a calculator (it is 3.375 inches³). Then multiply this result by (4/3)π:
V = (4π/3)(3.375 inches³) = 14.1 in³
Final answer:
To find the number of cubic units the tennis ball occupies, calculate its volume using the formula V = (4/3) * π * r^3, where r is the radius. The tennis ball occupies approximately 0.157 cubic feet of space.
Explanation:
To find the number of cubic units the tennis ball occupies, we need to calculate its volume. The volume of a sphere can be found using the formula V = (4/3) * π * r^3, where r is the radius. The diameter of the tennis ball is 3 inches, so the radius is half of that, or 1.5 inches. Converting to the nearest tenth, we have a radius of 1.5 inches = 0.15 feet.
Substituting this value into the volume formula, we get V = (4/3) * π * (0.15)^3 = (4/3) * π * 0.0375 = 0.157 cubic feet. Therefore, the tennis ball occupies approximately 0.157 cubic feet of space.

Suppose a single bacterium is placed in a bottle at 11:00am. It grows and at 11:01 divides into two bacteria. These two bacteria each grow and at 11:02 divide into four bacteria. Which grow and at 11:03 divide into eight bacteria, and so on. Now, suppose the bacteria continue to double every minute until the bottle is full at 12:00.
a. How many bacteria are in the bottle at 11:53?
b. What fraction of the bottle is full at that time?
Answer:
Number of bacteria at 11:53 for 53 min = [tex]2^{53}[/tex] = 9.007199 × [tex]10^{15}[/tex]
fraction that is full = [tex]2^{-7}[/tex]
Step-by-step explanation:
solution
Number of bacteria is express as here
Number of bacteria = [tex]2^t[/tex] ............1
so
bacteria at 1 min , 2 min and 3 min are
Number of bacteria at 1 min = [tex]2^1[/tex] = 2
Number of bacteria at 3 min = [tex]2^2[/tex] = 4
Number of bacteria at 3 min = [tex]2^3[/tex] = 8
and
as that Number of bacteria at 11:53 is for 53 min is
Number of bacteria at 11:53 for 53 min = [tex]2^{53}[/tex] = 9.007199 × [tex]10^{15}[/tex]
and
bottle is full at 12:00
so Number of bacteria at 12:00 for 60 min = [tex]2^{60}[/tex]
so fraction that is full = [tex]\frac{2^{53}}{2^{60}}[/tex]
fraction that is full = [tex]2^{-7}[/tex]
A geometric sequence is a sequence of numbers in which the ratio between consecutive terms is constant.
Number of bacteria present in bottle at 11:53 are [tex]2^{53}[/tex].
At that time, fraction [tex]2^{-7}[/tex] or 0.00781 of bottle is full.
Since, single bacterium is placed in a bottle at 11:00am. It grows and at 11:01 divides into two bacteria. These two bacteria each grow and at 11:02 divide into four bacteria. Which grow and at 11:03 divide into eight bacteria.
So, a sequence is obtained 1, 2, 4, 8, 16, 32, 64, .........
We can also write as,
At 11:00 am, [tex]2^0[/tex] bacteria
At 11:01 am, [tex]2^1[/tex] bacteria
At 11:02 am, [tex]2^2[/tex] bacteria
Similarly, At 11:53 am, Number of bacteria present in bottle are [tex]2^{53}[/tex].
When the bottle will be full, that time number pf bacteria will be [tex]2^{60}[/tex].
S0, fraction of bottle is full at 11:53 is [tex]2^{53} /2^{60} = 2^{-7} = 0.00781[/tex]

$750 at a 4% annual compound interest rate over a period 4 years
Which of the following statements are true of the data? Check all that apply.
The starting balance of the 3rd year is $811.20.
The interest earned in the 3rd year is $31.20.
The ending balance for the 3rd year is $843.65.
The interest earned in the 4th year is $33.75.
The ending balance for the 4th year is $874.85.
Answer:
The starting balance of the 3rd year is $811.20.
The ending balance for the 3rd year is $843.65.
The interest earned in the 4th year is $33.75.
Step-by-step explanation:
750 × (1 + 4%)^n
750 × (1.04)^n
750 × 1.04² = 811.2
(End of second year, starting of third year)
750 × 1.04³ = 843.648
In third year: 843.648 - 811.2
= 32.448
750 × 1.04⁴ = 877.39392
During the fourth year:
877.39392 - 843.648
33.74592
Answer:
The starting balance of the 3rd year is $811.20.
The ending balance for the 3rd year is $843.65.
The interest earned in the 4th year is $33.75.

Answer:
x = -4
Step-by-step explanation:
Square both sides:
[tex](\sqrt{-5-2x})^2 =(\sqrt{-1-x} )^2[/tex]
The square root and the square will cancel to leave simply the argument within the square root:
-5 - 2x = -1 - x
Now simply isolate the variable x:
x = -5 + 1 = -4
Check to see if x = -4 will work:
[tex]\sqrt{-5-2*(-4)} =\sqrt{-1-(-4)}[/tex]
[tex]\sqrt{3} =\sqrt{3}[/tex]
This works, so we know that x = -4 is a solution.

Supplementary angles are two angles that when added together equal 180 degrees, forming a straight line when placed beside each other.
Question in image. Thanks!
Answer:
B (i do also slightly lean towards C, but i'm pretty sure it would be B because it gives a specific measurement)
Step-by-step explanation:
If all angles that are either adjacent or opposite are supplementary, all angles must be 90°
If at all times adjacent sides are 5 inches, all sides are equal.
Knowing this, it has to be a square because all angles would be 90° and all sides would be equal.

Simplify the expression square root 18 + square root 50 .
Final answer:
To simplify the expression sqrt(18) + sqrt(50), find the square roots of 18 and 50 individually and then add them together.
Explanation:
To simplify the expression sqrt(18) + sqrt(50), we need to find the square roots of 18 and 50 individually and then add them together. The square root of 18 is approximately 4.2426 and the square root of 50 is approximately 7.0711. Adding these two values gives us approximately 11.3137. Therefore, the simplified expression is sqrt(18) + sqrt(50) = 11.3137.
