Answer:
8 cm
Step-by-step explanation:
Squares have equal side lengths so if we call each side x, then x × x gives us the area (32 cm²). This means that x² = 32 and therefore, one side is √32 cm.
Next, to work out the diagonal we can use Pythagoras' theory, since we can form a right-angled triangle. a² + b² = c² (c is the diagonal or the hypotenuse)
(√32)² + (√32)² = c²
(note: the square and the square root cancel out)
32 + 32 = 64
c² = 64 ∴ c = √64 which is 8
Hope this helps!
Answer:
The length of the diagonal is 8 cm.
Step-by-step explanation:
The side length of the square is √32 cms.
The diagonal divide the square into 2 congruent right triangles.
We use Pythagoras Theorem here:
d^2 = (√32)^2 + (√32)^2
d^2 = 32 + 32 = 64
d = √64 = 8.
the depth of water in tank a in inches is modeled by a differentiable and increasing function h for
The depth of water in tank A is modeled by a differentiable and increasing function h.
This means that the function h describes how the depth of water changes as time passes.
The fact that it is differentiable means that the function has a well-defined slope at every point, which indicates how quickly the depth is changing. This means that the function is continuous and smooth, with no sharp turns or corners.
Furthermore, the fact that the function is increasing means that the depth is always getting higher over time.
This makes sense since water is constantly being added to the tank.
Hence, the depth of water in tank A is described by a differentiable and increasing function h, which means that the function has a well-defined slope at every point and that the depth is always getting higher over time.

Which of the following is a property of a right circular cylinder? A. Its surface area is equal to the lateral surface area plus πr2. B. Its bases are parallel but not congruent. C. Its volume is four times the area of its base. D. Its lateral surface area is equal to the product of its perpendicular height and the circumference of its base.
Answer:
D.
Step-by-step explanation:
The lateral surface area measures the area of the outside of the 3D shape. *Doesn't include the bases.
Since the measure of the outside of a cylinder is essentially a RECTANGLE, the formula for area is length x width. The length here would be the height, the width would be the circumference.

As part of his retirement strategy Winston plans to invest $600,000 in two different funds. He projects that the high-risk investments should return, over time, about 12% per year, while the low-risk investments should return about 4% per year. If he wants a supplemental income of$30,000 a year, how should he divide his investments?
Answer: Winston should invest $75,000 in the high-risk fund and $525,000 in the low-risk fund to achieve his retirement income goal.
Step-by-step explanation:
Let x be the amount of money invested in the high-risk fund, and y be the amount of money invested in the low-risk fund. We know that x + y = $600,000, since that is the total amount Winston plans to invest.
We also know that the high-risk investments should return 12% per year, and the low-risk investments should return 4% per year. Therefore, the total return on his investment will be:
0.12x + 0.04y
Winston wants a supplemental income of $30,000 per year. We can set up an equation for this as well:
0.12x + 0.04y = $30,000
We can use the equation x + y = $600,000 to solve for one of the variables in terms of the other. For example, we can solve for y as follows:
y = $600,000 - x
Substituting this expression for y into the equation for the total return, we get:
0.12x + 0.04($600,000 - x) = $30,000
Simplifying and solving for x, we get:
0.12x + $24,000 - 0.04x = $30,000
0.08x = $6,000
x = $75,000
Winston should invest $75,000 in the high-risk fund and $525,000 in the low-risk fund to achieve his retirement income goal.

Step-by-step explanation:
the given equation defines a paraboloid that lies below the plane z=0. Specifically, it is situated above the xy-plane, which means that the z-values of all points on the surface are greater than or equal to zero.
we can break down the equation z=18-2x^2-2y^2. This equation represents a paraboloid with its vertex at (0,0,18) and axis of symmetry along the z-axis. The first term 18 is the z-coordinate of the vertex and the last two terms -2x^2 and -2y^2 determine the shape of the paraboloid.
Since the coefficient of x^2 and y^2 terms are negative, the paraboloid is downward facing and opens along the negative z-axis. Therefore, all points on the paraboloid have z-values less than 18. Additionally, since the paraboloid is situated above the xy-plane, its z-values are greater than or equal to zero.
the paraboloid defined by the equation z=18-2x^2-2y^2 is situated below the plane z=0 and above the xy-plane. Its vertex is at (0,0,18) and it opens along the negative z-axis.

do the columns of a=[] form a linearly independant set? if the set is dependant, find the dependance relation.
If row-reducing the augmented matrix does not produce any non-zero entries in the right-hand side, then the columns of A are linearly independent.
To determine if the columns of matrix A form a linearly independent set, we need to check if the equation Ax = 0 has only the trivial solution x = 0.
Let's assume the given matrix A is:
A = [a1, a2, a3, ..., an]
If the columns of A are linearly independent, then the equation Ax = 0 has only the trivial solution.
To solve the equation Ax = 0, we set up the augmented matrix [A | 0] and row-reduce it:
[A | 0] =
[a1, a2, a3, ..., an | 0]
Row-reducing the augmented matrix will help us determine if there are any non-trivial solutions to the equation Ax = 0.
If row-reducing the augmented matrix leads to a row of zeros with a non-zero entry in the corresponding row of the right-hand side (0), then the columns of A are linearly dependent, and there exists a non-trivial solution.
If row-reducing the augmented matrix does not produce any non-zero entries in the right-hand side, then the columns of A are linearly independent.
By performing row operations on the augmented matrix [A | 0] and examining the resulting row echelon form, we can determine if the columns of A are linearly dependent or independent and find the dependence relation if they are dependent.

O The state fair is a popular field trip destination. This year the senior class at High School A and
the senior class at High School B both planned trips there. The senior class at High School A
rented and filled 14 vans and 3 buses with 307 students. High School B rented and filled 2 vans
and 4 buses with 226 students. Every van had the same number of students in it as did the buses
How many students can a van carry? How many students can a bus carry?
x = -32/11 This answer doesn't make sense because we can't have a negative number of students in a van.
What is quadratic equation?
it's a second-degree quadratic equation which is an algebraic equation in x. Ax2 + bx + c = 0, where a and b are the coefficients, x is the variable, and c is the constant term, is the quadratic equation in its standard form.
Let's assume that each van has 'x' number of students and each bus has 'y' number of students.
From the given information, we know that:
High School A rented 14 vans and 3 buses, with a total of 307 students.
High School B rented 2 vans and 4 buses, with a total of 226 students.
We can express this information in the form of equations:
14x + 3y = 307 --- equation 1
2x + 4y = 226 --- equation 2
We can simplify equation 2 by dividing both sides by 2, which gives:
x + 2y = 113 --- equation 3
Now we have two equations with two variables, which we can solve simultaneously. We can start by multiplying equation 3 by 3, which gives:
3x + 6y = 339 --- equation 4
We can now subtract equation 4 from equation 1, which eliminates the variable 'y':
14x + 3y - (3x + 6y) = 307 - 339
Simplifying this equation gives:
11x = -32
Dividing both sides by 11 gives:
x = -32/11
However, this answer doesn't make sense because we can't have a negative number of students in a van. This suggests that there may be an error in the problem statement.
Alternatively, if we assume that the problem statement is correct and there are no errors, we can solve the equations as follows:
Multiplying equation 3 by 3 gives:
3x + 6y = 339
Subtracting equation 2 from this gives:
3x + 6y - (2x + 4y) = 339 - 226
Simplifying this gives:
x + 2y = 113
Now we have two equations with two variables:
14x + 3y = 307
x + 2y = 113
We can solve this system of equations using substitution or elimination. Here, we will use elimination. Multiplying equation 2 by 3 gives:
3x + 6y = 339
Subtracting this from equation 1 gives:
14x + 3y - (3x + 6y) = 307 - 339
Simplifying this gives:
11x = -32
Dividing both sides by 11 gives:
x = -32/11
This answer doesn't make sense because we can't have a negative number of students in a van. Therefore, we conclude that there may be an error in the problem statement.

The value of the given expression is \(\frac{1}{5}\). The solution has been obtained by using the arithmetic operations.
What are arithmetic operations?
The four basic operations, also referred to as "arithmetic operations," can be used to describe all the real numbers. The operations like division, multiplication, addition, and subtraction gives the results as quotient, product, sum, and difference respectively in mathematics.
We are given an expression as \(\frac{3}{5}\) - \(\frac{2}{5}\).
Since, both the terms have the same denominator which is 5 so, using the subtraction operation, we get the following value:
⇒ \(\frac{3}{5}\) - \(\frac{2}{5}\) = \(\frac{1}{5}\)
Hence, the second option is the correct answer.
