Answer:

x = 45.5

Step-by-step explanation:

Move one side of the equation to the other side of the equal sign.

4 + x = 5x + 2

x = 5x - 2

=4x - 2

Then put the 180 on the empty side because the total is 180.

180 = 4x - 2

Then solve for x

182 = 4x

45.5 = x

Answer:

Substitution ( even though I prefer Common sense)

The correct sequence of transformations that could be applied to square M to map it to square P is  a reflection over the y-axis followed by a dilation by a factor greater than 1

Reflection over the y-axis reflects the square across the y-axis, effectively switching the positions of the points on the left and right sides of the square.

This is necessary because square M is positioned along the y-axis, while square P is positioned along the x-axis.

After reflecting the square over the y-axis, we need to scale it up to match the size of square P.

Since square P is positioned along the x-axis, which is a greater distance from the origin compared to the y-axis, a dilation by a factor greater than 1 is required to enlarge the square accordingly.

The length ||x||2 is positive, we must have λ

of A is real.

Recall that the eigenvalues of a real symmetric matrix are real.

Let λ be a (real) eigenvalue of A and let x be a corresponding real eigenvector. That is, we have

Ax=λx.

Then we multiply by xᵀ on left and obtain

xᵀAx = λxᵀx = λ || x || 2.

The left hand side is positive as A is positive definite and x is a nonzero vector as it is an eigenvector.

Since the length ||x||2 is positive, we must have λ

Answer:

the answer I got was 82,944

Step-by-step explanation:

12×12=24×12=288×24=6,912×12=82,844

- Span{v1, v2, v3, 0} is equal to the span of {v1, v2, v3}.
- Span{v1, v1-v2, v3} is equal to the span of {v1, v2, v3}.
- Span{v1, v2} is NOT equal to the span of {v1, v2, v3}.

Let's analyze each of the sets of vectors to determine if they are equal to the span of {v1, v2, v3}:
1. Span{v1, v2, v3, 0}:
This set is equal to the span of {v1, v2, v3} because adding the zero vector (0) does not affect the linear independence or the span of the other vectors.

A span is the set of all possible linear combinations of the vectors, and since the zero vector does not change the linear combinations, the span remains the same.
2. Span{v1, v1-v2, v3}:
This set is also equal to the span of {v1, v2, v3}.

The reason is that the vector (v1-v2) can be written as a linear combination of v1 and v2: (v1-v2) = 1*v1 + (-1)*v2.

Since all vectors in this set can be expressed as linear combinations of {v1, v2, v3}, the span remains the same.
3. Span{v1, v2}:
This set is NOT equal to the span of {v1, v2, v3} because it is missing the vector v3.

Since v1, v2, and v3 are linearly independent, removing one of them (v3 in this case) means that the set cannot span the same space as {v1, v2, v3}.

It has a lower dimension, and therefore, the span is different.

Answer: w = -238

Step-by-step explanation:

\(34=\frac{-w}{7}\)

Switch sides

\(\frac{-w}{7} =34\)

Multiply both sides by 7

\(\frac{7\left(-w\right)}{7} =34\cdot \:7\)

Simplify

-w = 238

Divide both sides by -1

\(\frac{-w}{-1}=\frac{238}{-1}\)

Simplify

w = -238

To eliminate the roots in 1.1 and 1.2, we can use trigonometric substitution. In 1.1, we can substitute x = 4 sin(theta) to eliminate the root of 4. In 1.2, we can substitute z = 7 sin(theta) to eliminate the root of 7.

1.1. V64+2 + 1 We can substitute x = 4 sin(theta) to eliminate the root of 4. This gives us:

V64+2 + 1 = V(16 sin^2(theta) + 2 + 1) = V16 sin^2(theta) + V3 = 4 sin(theta) V3 1.2. V4z2 – 49

We can substitute z = 7 sin(theta) to eliminate the root of 7. This gives us:

V4z2 – 49 = V4(7 sin^2(theta)) – 49 = V28 sin^2(theta) – 49 = 7 sin(theta) V4 – 7 = 7 sin(theta) (2 – 1) = 7 sin(theta)

Here is a more detailed explanation of the substitution:

In 1.1, we know that the root of 4 is 2. We can substitute x = 4 sin(theta) to eliminate this root. This is because sin(theta) can take on any value between -1 and 1, including 2.

When we substitute x = 4 sin(theta), the expression becomes V64+2 + 1 = V(16 sin^2(theta) + 2 + 1) = V16 sin^2(theta) + V3 = 4 sin(theta) V3

In 1.2, we know that the root of 7 is 7/4. We can substitute z = 7 sin(theta) to eliminate this root. This is because sin(theta) can take on any value between -1 and 1, including 7/4.

When we substitute z = 7 sin(theta), the expression becomes: V4z2 – 49 = V4(7 sin^2(theta)) – 49 = V28 sin^2(theta) – 49 = 7 sin(theta) V4 – 7 = 7 sin(theta)

The constant of proportionality is the cost per pound of oranges, and it is 3.47 dollars per pound.

A general proportional relationship can be written as:

y = k*x

Where k is the constant of proportionality.

In this case, we can define the variables:

x = number of pounds oranges.

y = cost of these oranges.

Here we know that the cost of 6 pounds of oranges is $20.82, replacing these values we will get:

$20.82 = k*6 lb

$20.82/6lb = k

$3.47 per lb = k

Step-by-step explanation:

Thus, the company must consider fixed monthly payments of amount $497.92 into the account to reach $97,000 in 13 years.

To find the monthly payment needed to reach $97,000 in 13 years, we can use the sinking fund formula:

FV = PMT * [(1 + i)^n - 1] / i

where:
FV = future value ($97,000)
PMT = monthly payment (unknown)
i = monthly interest rate (3.2% compounded monthly, which is 0.032 / 12 = 0.002667)
n = number of months (13 years * 12 months/year = 156 months)

Rearrange the formula to solve for PMT:

PMT = FV * i / [(1 + i)^n - 1]

PMT = 97,000 * 0.002667 / [(1 + 0.002667)^156 - 1]

PMT ≈ 497.92

So, the company should make fixed monthly payments of approximately $497.92 into the account to reach $97,000 in 13 years.

To find the surface area of the sphere with a unit cube inscribed, we first need to determine the radius of the sphere. A unit cube has side length 1, and its vertices are at a distance of 1 unit from each other. Since all eight vertices of the cube are on the sphere, we can consider the longest diagonal of the cube to calculate the diameter of the sphere.

The longest diagonal of the cube can be calculated using the Pythagorean theorem in three dimensions: the square of the diagonal (d²) is equal to the sum of the squares of the side lengths (a² + b² + c²), where a, b, and c are the side lengths of the unit cube. In this case, a = b = c = 1. So, d² = 1² + 1² + 1² = 3. Thus, d = √3.

The diameter (d) of the sphere is equal to the longest diagonal of the cube. Therefore, the radius (r) of the sphere is half of the diameter: r = d/2 = √3/2.

Now that we have the radius, we can calculate the surface area (A) of the sphere using the formula: A = 4πr². Plugging in the radius, we get:

A = 4π(√3/2)² = 4π(3/4) = 3π.

So, the surface area of the sphere is 3π square units.

Each function out of the given 4 functions has a horizontal asymptote.

An asymptote is a straight line that continually approaches a given curve but does not meet it at any finite distance.

Mathematically, if y=k is a horizontal asymptote for a function x=f(y) the limiting value of the function is infinity as y→k.

Out of the given curves, for every curve limiting value of the function tends to infinity as y→0

So, each function out of the given 4 functions has a horizontal asymptote.

Step-by-step explanation:

As we know vertically opposite angles are equal . So ,

x + 90= 125

x = 125-90 = 35°

Answer:

35

Step-by-step explanation:

125 + 90(APC) + DPA + EPB + x = 360

215 + DPA + EPB + x = 360

DPA = 180 - 125 = 55

EPB = DPA

EPB = 55

X = 90(EPC) - EPB

X = 90 - 55

X = 35

OR easy way

DB is a straight line so angels on it add up to 180

EPB = 180 - 125

EPB = 55

X = 90(EPC) - EPB

X = 90 - 55

X = 35

Answer:

Probability that a student who passed the test did not  complete the homework = 0.07

Step-by-step explanation:

Given:

Total number of students = 28

Number of students who passed the test = 18

Number of students who completed  the assignment = 23

Number of students who passed the test and also completed the  assignment = 16

To find: probability that a student who passed the test did not  complete the homework

Solution:

Probability refers to chances of occurrence of some event.

Probability = number of favorable outcomes/total number of outcomes

Let A denotes the event that students passed the test and B denotes the event that students completed  the assignment

P(A only) = \(P(A)-P(A\cap B)\)

Here,

\(P(A)=\frac{18}{28}\,,\,P(A\cap B)=\frac{16}{28}\)

So,

\(P(A\,\,only)=\frac{18}{28}-\frac{16}{28}=\frac{2}{28}=\frac{1}{14}=0.07\)

Therefore,
