The ratio of the measures of the sides of a triangle is 9:12:5. If the perimeter of the triangle is 130 feet, find the measure of the sides.
Answers
Answer:
The sides of the triangle are 45, 60, and 25 ft
Step-by-step explanation:
9 + 12 + 5 equals 26.
Now we need to get the first two sides.
9/26 × 130 = 1170/26 = 45
In order to obtain the other side;
12/26 = 1560/26 = 60
And to obtain the third side:
5/26 × 130 =650/26 = 25
Therefore, the sides of the triangle are 45, 60, and 25 ft

The measure of one acute angle of a right triangle is 6 less than twice the measure of the other acute angle. Find the measure of each acute angle.
Answers
The measure of each of the acute angles of the right triangle is 32° and 58°.
A right triangle is a kind of triangle which has a right angle (90°) and two acute angles (less than 90°).
Let x = measure of one of the acute angles
If the measure of one acute angle of a right triangle is 6 less than twice the measure of the other acute angle, then
measure of the other acute angle = 2x - 6
The sum of all the angles of any triangle is equal to 180°. Hence,
90° + x + 2x - 6 = 180°
Solve for the value of x.
3x = 96
x = 32
Solve for the measure of the other acute angle.
2x - 6 = 2(32) - 6 = 58
Hence, the two angles are 32° and 58°.

Answers
The t-distribution value is -1.67 for the given mean samples of 35 and 45. Thus, option B is correct.
M₁ = 35
M₂ = 45
SM1-M2 = 6.00
The t-value or t-distribution formula is calculated from the sample mean which consists of real numbers. To calculate the t-value, the formula we need to use here is:
t = (M₁ - M₂) / SM1-M2
Substituting the given values into the formula:
t = (35 - 45) / 6.00
t = -10 / 6.00
t = -1.67
Therefore, we can conclude that the value of t is -1.67 for the samples given.

what conditions are required for the inference, part b, to be valid? are these conditions reasonably satisfied?
Answers
For the inference in part b to be valid, the conditions required are reasonable satisfaction.
To determine if the conditions for the inference in part b are reasonably satisfied, we need to consider the specific details of the inference.
However, in general, the conditions for a valid inference typically include logical reasoning, accurate data, reliable sources, and relevant contextual information.
These conditions ensure that the conclusion drawn from the inference is supported by evidence and does not contain logical fallacies or biases. It is important to evaluate the quality and reliability of the information used in the inference to determine if the conditions are reasonably satisfied.

Answers
The set of all symmetric 3x3 matrices satisfies all three conditions for a subspace, it is indeed a subspace of M33
To determine whether the set of all symmetric 3x3 matrices is a subspace of M33, we need to check if it satisfies the three conditions for a subspace:
Closure under addition: If A and B are both symmetric 3x3 matrices, then A+B will also be a symmetric 3x3 matrix since \((A+B)^T = A^T + B^T = A + B\). Therefore, the set is closed under addition.
Closure under scalar multiplication: If A is a symmetric 3x3 matrix and c is a scalar, then cA will also be a symmetric 3x3 matrix since \((cA)^T = cA^T = cA\). Therefore, the set is closed under scalar multiplication.
Contains the zero vector: The zero vector in M33 is the matrix of all zeroes. This matrix is also a symmetric 3x3 matrix since all its entries are equal. Therefore, the set contains the zero vector.
Since the set of all symmetric 3x3 matrices satisfies all three conditions for a subspace, it is indeed a subspace of M33.

find the length of the spiraling polar curve r = 7 e^{4 \theta} from 0 to 2 \pi .
Answers
Answer: 46.619 units.
Step-by-step explanation:
To find the length of the spiraling polar curve, we need to use the formula:
L = int_a^b sqrt[r^2 + (dr/d\theta)^2] d\theta
where r is the polar curve, dr/d\theta is its derivative with respect to theta, and a and b are the limits of integration.
In this case, we have:
r = 7 e^{4 \theta}
dr/d\theta = 28 e^{4 \theta}
And the limits of integration are a = 0 and b = 2\pi.
Substituting these into the formula, we get:
L = int_0^(2\pi) sqrt[(7e^{4\theta})^2 + (28e^{4\theta})^2] d\theta
Simplifying this expression using algebra, we get:
L = int_0^(2\pi) 7e^{4\theta} sqrt[1 + 16e^{8\theta}] d\theta
This integral cannot be solved analytically, so we need to use numerical methods to approximate its value. One way to do this is to use a numerical integration technique such as the trapezoidal rule or Simpson's rule.
Using Simpson's rule with a step size of h = \pi/1000, we get:
L \approx 46.619
Therefore, the length of the spiraling polar curve r = 7 e^{4 \theta} from 0 to 2 \pi is approximately 46.619 units.

The cost of each pencil is ____cents.
Answers
A group of people ordered pencils, and the bill was $1.87 if the original price of each was 15 cents, and the price has risen, 1he cost of each pencil is 16 cents.
We know that the total bill for the pencils was $1.87, which is equal to 187 cents. The original price of each pencil was 15 cents. Since the price has risen, the difference between the new price and the original price is x - 15 cents.
If a group of people ordered the pencils, we can divide the total bill by the price per pencil to find the number of pencils purchased.
So we have the equation:
187 cents = (x cents - 15 cents) * (number of pencils)
To find the cost of each pencil, we need to solve for x.
Dividing both sides of the equation by (x - 15) cents, we get:
187 cents / (x - 15 cents) = (number of pencils)
We don't have the exact number of pencils, but we know it is a positive integer. We can observe that the left side of the equation is a whole number (since 187 is divisible by x - 15), so the right side (number of pencils) should also be a whole number.
Now, we can look for values of x that make the right side of the equation a whole number. Let's try different values of x:
For x = 16 cents:
187 cents / (16 cents - 15 cents) = 187 cents / 1 cent = 187 pencils (whole number)
For x = 17 cents:
187 cents / (17 cents - 15 cents) = 187 cents / 2 cents = 93.5 pencils (not a whole number)
We can see that x = 16 cents satisfies the condition where the right side of the equation is a whole number.
Therefore, each pencil costs 16 cents.

A rectangular parallelepiped has sides 3 cm, 4 cm, and 5 cm, measured to the nearest centimeter.a. What are the best upper and lower bounds for the volume of this parallelepiped?b. What are the best upper and lower bounds for the surface area?
Answers
The best lower bound for the volume is 24 cm³, and the best upper bound is 120 cm³ and the best lower bound for the surface area is 52 cm², and the best upper bound is 148 cm².
a. To determine the best upper and lower bounds for the volume of the rectangular parallelepiped, we can consider the extreme cases by rounding each side to the nearest centimeter.
Lower bound: If we round each side down to the nearest centimeter, we get a rectangular parallelepiped with sides 2 cm, 3 cm, and 4 cm. The volume of this parallelepiped is 2 cm * 3 cm * 4 cm = 24 cm³.
Upper bound: If we round each side up to the nearest centimeter, we get a rectangular parallelepiped with sides 4 cm, 5 cm, and 6 cm. The volume of this parallelepiped is 4 cm * 5 cm * 6 cm = 120 cm³.
Therefore, the best lower bound for the volume is 24 cm³, and the best upper bound is 120 cm³.
b. Similar to the volume, we can determine the best upper and lower bounds for the surface area of the parallelepiped by considering the extreme cases.
Lower bound: If we round each side down to the nearest centimeter, the dimensions of the parallelepiped become 2 cm, 3 cm, and 4 cm. The surface area is calculated as follows:
2 * (2 cm * 3 cm + 3 cm * 4 cm + 4 cm * 2 cm) = 2 * (6 cm² + 12 cm² + 8 cm²) = 2 * 26 cm² = 52 cm².
Upper bound: If we round each side up to the nearest centimeter, the dimensions become 4 cm, 5 cm, and 6 cm. The surface area is calculated as follows:
2 * (4 cm * 5 cm + 5 cm * 6 cm + 6 cm * 4 cm) = 2 * (20 cm² + 30 cm² + 24 cm²) = 2 * 74 cm² = 148 cm².
Therefore, the best lower bound for the surface area is 52 cm², and the best upper bound is 148 cm².
