Answer:
V = 14.14in^3
Step-by-step explanation:
Use the formula V = 3/4πr^2 to get the volume of a sphere
Substitute r for 1.5 in
V = 3/4π(1.5)^2
V = 14.137166941154in^3
Round to the nearest hundredth to find the approximate volume
V = 14.14in^3
The following examples illustrate the commutative property of multiplication.
5 · 2 · 9 = 2 · 5 · 9
Study the examples, then choose the statement that best describes the property.
a · b = a ÷ b
a · (b · c) = (a · b) · c
a · b = b · a
a · b = a · c
The statement that best describes the property is a · b = b · a.
What is commutative property?The commutative property of multiplication states that if there are three numbers x, y, and z, then x × y × z = z × y × x = y × z × x or another possible arrangement can be made.
If you observe the given equation, you will find that the commutative property can be applied. If x = 131, and y = 56 and z = 72, then we know that 131 x 56 x 72 = 72 x 131 x 56.
Given statement:
5 · 2 · 9 = 2 · 5 · 9
So, we can see that only the place has been changed
So, it is commutative property
Hence, the correct statement is a · b = b · a

The x-intercept of a function y = f(x) are the real solutions of the
equation f(x) = 0.
The given statement "The x-intercept of a function y = f(x) are the real solutions of the equation f(x) = 0." is True because the x-intercepts of a function y = f(x) are points on graph where function crosses x-axis.
At these points, the value of y (f(x)) is equal to 0. In other words, the x-intercepts are the real solutions of the equation f(x) = 0.
To find the x-intercepts of a function, we set f(x) equal to 0 and solve for x. The solutions to this equation will be the x-coordinates of the x-intercepts.
For example, given the function y = 2x - 6, to find the x-intercept, we set y (f(x)) equal to 0:
0 = 2x - 6
Now, solve for x:
2x = 6
x = 6 / 2
x = 3
The x-intercept is (3, 0) since at x = 3, the value of y (f(x)) is 0.
In conclusion, the statement is true. The x-intercepts of a function y = f(x) are the real solutions of the equation f(x) = 0.

Given: f(x)=-2x+2 and g(x)=4x+8 which table set up is correct to solve the equation f(x)=g(x)
The solution to f(x) = g(x) is x = -1.
To find the value of x that satisfies the equation f(x) = g(x), we set the two
functions equal to each other and solve for x.
This gives us the equation -2x + 2 = 4x + 8.
Combining like terms, we get 6x = -6.
Dividing both sides by 6, we find that x = -1.
Therefore, the solution to f(x) = g(x) is x = -1.

Step-by-step explanation:
4) 416 = 2x² - 6x
2x² - 6x - 416 = 0
x² - 3x - 208 = 0
x² - 16x + 13x - 208 = 0
x(x - 16) + 13(x - 16) = 0
(x - 16)(x + 13) = 0
x = 16, -13(not possible)
So 16 rows
5) y = a(x - h)² + k
y = a(x - 3)² - 7
When x = 1, y = -10
-10 = a (1 - 3)² - 7
-10 = 4a - 7
4a = -3
a = -¾
y = -¾(x - 3)² - 7

In a pair of complementary angles, the measurement of the larger angle is three times that of the smaller angle. Find the measurements of the two angles.
In a pair of complementary angles, the larger angle is three times the smaller angle. The measurements of the two angles are 22.5 degrees and 67.5 degrees.
Explanation:In a pair of complementary angles, the larger angle and the smaller angle add up to 90 degrees because complementary angles are two angles that add up to a right angle.
Let's assume the smaller angle is x. According to the given information, the larger angle is three times the smaller angle, so it would be 3x.
Now, we can set up an equation to solve for x. Since the sum of the angles is 90 degrees, we have:
x + 3x = 90
Combining like terms, we find 4x = 90. Dividing both sides by 4, we get x = 22.5.
Therefore, the smaller angle measures 22.5 degrees and the larger angle measures 3 times that, which is 67.5 degrees.

A basketball team scored 82 points
in a game. The players made no free
throws and the number of two-point
ifield goals was 2 more than 5 times the
number of three-point Shots.
How many of each Shot did they make
Number of 3-point shots are 13 and number of 2-point shots are 69
Step-by-step explanation:
Step 1: Let the number of 3-point shots be x, then the number of 2-point shots will be 5x + 2. Total points = 82. Form an equation to find x.⇒ 82 = x + 5x + 2 = 6x + 2
⇒ 80 = 6x
∴ x = 80/6 = 13.33 ≈ 13
∴ 5x + 2 = 66.67 + 2 = 68.67 ≈ 69

Russel wants to buy three ties and a belt and must spend no more that $80. The belt costs $28.50. If three ties are the same price, then how much can he pay for each tie?
Answer:
About $17.16
Step-by-step explanation:
$80-$28.50= 51.5
Then you divide that by 3 (for the 3 ties)
Russel can spend a maximum of $17.17 on each tie after accounting for the cost of the belt.
To determine how much Russel can spend on each tie, we first need to account for the cost of the belt. The belt costs $28.50 and Russel's total budget is $80. Therefore, the remaining amount for the ties is $80 - $28.50 = $51.50.
Since Russel wants to buy three ties, we need to find the maximum price he can pay for each tie. We can do this by dividing the remaining budget by the number of ties:
$51.50 / 3 = $17.17
Therefore, Russel can spend a maximum of $17.17 on each tie.

Volume of rectangular prism:
6*26*22 = 3432
Volume of triangular prism:
1/2 of rectangular prism - 3432/2 = 1216
Answer:
