Select each expression that can be factored as a difference of squares. 16x^(2)+25y^(2) x^(3)-125 25x^(2)y^(2)-64z^(2) 4x^(2)-9y^(2)

If the values of A and B make the equation 35x – 29/x²-3x+2 = A/x-1 +b/x-2 true for all values of x for which it is defined, A+B is 35.

The given equation is 35x - 29/(x² - 3x + 2) = A/(x - 1) + B/(x - 2).

We can simplify the denominator of the second term on the left hand side by factoring it:

35x - 29/[(x - 1)(x - 2)] = A/(x - 1) + B/(x - 2)

Now, we can multiply both sides of the equation by (x - 1)(x - 2) to get rid of the fractions:

35x(x - 1)(x - 2) - 29 = A(x - 2) + B(x - 1)

Expanding the left hand side gives us:

35x³ - 70x² + 35x - 29 = A(x - 2) + B(x - 1)

Now, we can compare the coefficients of x on both sides of the equation to find the values of A and B. The coefficient of x on the left hand side is 35, and on the right hand side it is A + B. Therefore, A + B = 35.


Therefore, the values of A and B make the equation 35x – 29/x^2-3x+2 = A/x-1 +b/x-2 true for all values of x for which it is defined is 35.

x intercept is the point on the line where it touches the X axis.

y intercept is the point on the line where it touches the Y axis.

Given equation is,

y = 200 - 25x

where y is the total amount in Amanda's school lunch account after purchasing lunches for x weeks.

x intercept is the point on X axis. Any point on x axis has y coordinate 0.

So x intercept is the x coordinate when y coordinate is 0.

0 = 200 - 25x

25x = 200

x = 8

This means that the amount in the account will become 0, after purchasing lunch for 8 weeks.

y intercept is the y coordinate when x coordinate = 0.

y = 200 - (25 × 0)

a)T(u) + T(v) T is a linear transformation

b)[3 -2 ; 2 0]

c)T is one-to-one.

a) To prove that T is a linear transformation, we need to show that it satisfies two conditions.

1. Additivity: T(u + v) = T(u) + T(v)
Let u = [u1, u2] and v = [v1, v2], then
T(u + v) = T([u1 + v1, u2 + v2]) = [3(u1 + v1) - 2(u2 + v2), 2(u2 + v2)]
= [3u1 - 2u2 + 3v1 - 2v2, 2u2 + 2v2]
= [3u1 - 2u2, 2u2] + [3v1 - 2v2, 2v2]
= T(u) + T(v)

2. Homogeneity: T(cu) = cT(u)
Let u = [u1, u2] and c be any scalar, then
T(cu) = T([cu1, cu2]) = [3cu1 - 2cu2, 2cu2] = c[3u1 - 2u2, 2u2]
= cT(u)

Therefore, T satisfies both conditions, and is a linear transformation.

b) The standard matrix of T is the matrix A = [3 -2 ; 2 0]

c) To determine whether T is one-to-one, we look at the matrix A. Since the matrix A has a non-zero determinant, which is equal to -4, then T is one-to-one.

The value of x and y are

x=100° y=100°

In an equilateral triangle,

Each angle = 60°

∴ a + a + 100° = 180°

⇒ 2a + 100° = 180°

⇒ 2a = 180° – 100° = 80°

∴ a = 80°/2 = 40° ∴ x = 60° + 40° = 100°

And y = 60° + 40° = 100°

An equilateral triangle in geometry is a triangle with equally long sides. The three angles opposite the three equal sides are equal in size because the three sides are equal. As a result, with each angle measuring 60 degrees, it is sometimes referred to as an equiangular triangle. Equilateral triangles have the same area, perimeter, and height formula as other kinds of triangles.

An equilateral triangle has a predictable shape. By combining the words "Equi" (which means equal) and "Lateral," which refers to sides, the word "Equilateral" is created. Due to the equality of its sides, an equilateral triangle is also known as a regular polygon or regular triangle.

from the question:

In an equilateral triangle,

Each angle = 60°

Let each base angle = a

∴ a + a + 100° = 180°

⇒ 2a + 100° = 180°

⇒ 2a = 180° – 100° = 80°

∴ a = 80°/2 = 40° ∴ x = 60° + 40° = 100°

The value of k that makes the remainder of the polynomial equal to -6 when divided by x + 1 is k = 5.

To find the value of k that makes the remainder of the polynomial P(x) = kx3 - 4x2 + x + 4 equal to -6 when divided by x + 1, we can use the Remainder Theorem. The Remainder Theorem states that if a polynomial P(x) is divided by x - a, the remainder is P(a).

In this case, we are dividing by x + 1, so we can rewrite this as x - (-1). Therefore, a = -1 and we can plug this value into the polynomial to find the remainder:

P(-1) = k(-1)3 - 4(-1)2 + (-1) + 4

Simplifying this equation gives us:

P(-1) = -k - 4 - 1 + 4

P(-1) = -k - 1

Since we want the remainder to be -6, we can set P(-1) equal to -6 and solve for k:

-k - 1 = -6

-k = -5

k = 5

The equation which represents exponential growth is y = (1.2)* and equation which represents exponential decay is y = (.71)*,  y = 0(6.3)* represents a constant function.

Consider the function:

[tex]y = a(1\pm r)^m[/tex]

where m is the number of times this growth/decay occurs, a = initial amount, and r = fraction by which this growth/decay occurs.

If there is plus sign, then there is exponential growth happening by r fraction or 100r %

If there is negative sign, then there is exponential decay happening by r fraction or 100r %

We are given that;

c. y = (1.2)*

d. y = 0(6.3)*

e. y = (.71)*

a.) The equation and graph that show exponential growth is y = (1.2)x. This is because the base of the exponent (1.2) is greater than 1, so as x increases, the value of y increases at an increasing rate. The graph of y = (1.2)x is an upward-curving curve that gets steeper as x increases.

b.) The equation and graph that show exponential decay is y = (0.71)x. This is because the base of the exponent (0.71) is between 0 and 1, so as x increases, the value of y decreases at a decreasing rate. The graph of y = (0.71)x is a downward-curving curve that flattens out as x increases.

Therefore, exponential growth shows y = (1.2)* whereas y = (.71)* show exponential decay.

Answer:

DE = 3

Step-by-step explanation:

A scale factor consists of two or more shapes who look the same but have different scales or measures. A scale factor of [tex]\frac{1}{2}[/tex] means that the new shape is half the size of the original.

To solve for a missing length, we can use this expression:

Inserting our numbers into the expression:

Subtract 64 from each side:

Therefore, the missing side length is 6.

Looking at the side CB, it is 10 units long. If the new shape is 5 units long, that means that the scale factor from shape 1 to 2 is [tex]\frac{1}{2}[/tex], meaning it is half its size. If the new shape is half its size, we can use this expression to solve for the missing length:

Therefore, the measure of DE is 3.

Babe and Ruth are 675 miles apart and headed straight toward each

other. If Babe is traveling at 40 mph and Ruth is traveling at 35

mph, it will take 9 hours before they meet.

To determine the time it will take for Babe and Ruth to meet, we need to use the formula:

time = distance / rate

Since they are traveling towards each other, we can add their speeds to get the combined speed at which they are approaching each other.

combined speed = Babe's speed + Ruth's speed

combined speed = 40 mph + 35 mph

combined speed = 75 mph

Now we can plug in the values we have into the formula:

time = distance / combined speed

time = 675 miles / 75 mph

time = 9 hours

Therefore, it will take 9 hours before Babe and Ruth meet.

f(x) = 10 - 3x over the domain x ≤ 9

f(x) = 5x - 1 over the domain x ≥ -7

From the question, we are to determine the linear function that have minimum value but no maximum value

The decreasing function f(x) = 10 - 3x over the domain x ≤ 9 has a minimum value but no maximum value.

Domain: x ≤ 9

This function is decreasing since the slope is negative.

The minimum value occurs at x = 9, where f(9) = 10 - 3(9) = -17.

Since the slope is negative, the function continues to decrease without bound as x approaches negative infinity.

The decreasing function f(x) = 5x - 1 over the domain x ≥ -7 has a minimum value but no maximum value.

Domain: x ≥ -7

This function is increasing since the slope is positive.

The minimum value occurs at x = -7, where f(-7) = 5(-7) - 1 = -36.

Since the slope is positive, the function continues to increase without bound as x approaches positive infinity.

Hence, the functions are:

f(x) = 10 - 3x over the domain x ≤ 9

The population will reach 7 million people approximately 21.67 years after 2002. Rounding to the nearest whole number, this corresponds to the year 2024.

The year when the population reaches 7 million can be determined using the population model given, f(x) = 6.7(1.0032)x, where x is the number of years following 2002.

When we solve for x while setting f(x) equal to 7, we obtain:

[tex]7 = 6.7(1.0032)^x[/tex]

By multiplying both sides by 6.7, we obtain:

[tex]1.04478 = 1.0032^x[/tex]

When we take the natural logarithm of both sides, we obtain:

ln(1.04478) = x * ln (1.0032)

After finding x, we obtain:

x = ln(1.04478) / ln (1.0032)

x ≈ 21.67

Hence, approximately 21.67 years after 2002, the population will reach 7 million. This corresponds to the year 2024 when rounded to the next whole number.

2. Apply the first row operation, 3R3​+R1​⇒R1​, to the identity matrix by adding three times the third row to the first row:
I = [[1+3(0), 0+3(0), 0+3(1)], [0, 1, 0], [0, 0, 1]]
I = [[1, 0, 3], [0, 1, 0], [0, 0, 1]]

3. Apply the second row operation, −7R2​⇒R2​, to the identity matrix by multiplying the second row by -7:
I = [[1, 0, 3], [0*(-7), 1*(-7), 0*(-7)], [0, 0, 1]]
I = [[1, 0, 3], [0, -7, 0], [0, 0, 1]]

4. The resulting matrix, I, is the matrix B that we are looking for:
B = [[1, 0, 3], [0, -7, 0], [0, 0, 1]]

Therefore, the matrix B such that BA gives the matrix resulting from A after the given row operations are performed.3R3​+R1​⇒R1​−7R2​⇒R2​​B= is B = [[1, 0, 3], [0, -7, 0], [0, 0, 1]].

Answer: 1250 students

Step-by-step explanation:

20% + 40% + 20% = 80%

100% - 80% = 20%

If 250 is 20%, then it's just 250 x 5 = 1250

It can be inferred that milk chocolate does have a lower melting point than dark chocolate and that the rate at which chocolate melts is influenced by a number of variables, including composition, temperature, as well as humidity.

According to the facts provided, it is anticipated that within 64 seconds, half of the milk chocolate brands will melt. According to their composition as well as melting point, different milk chocolate brands may melt sooner or later than 64 seconds.

However, it is believed that none of the dark chocolate brands are expected to melt before 64 seconds have passed and that their melting time actually begins after 200 seconds.

The correct coordinates of N' is (-3, -4).    

Rotation of coordinates involves changing the orientation of a point or object in a plane about a fixed point called the center of rotation.

This process can be accomplished by applying a set of transformation rules to the original coordinates of the object.

When a point (x, y) rotated about the origin at 180° then the coordinates resultant point are (-x, -y).

Here we have

Point N has coordinates (3, 4)

Given that the point N is rotated about 180°  

As we know when the point (x, y) rotated about the origin at 180° then the resultant point is (-x, -y)

Here (3, 4) is rotated about 180°

The resultant point N' is (-3, -4)      

Therefore,

The correct coordinates of N' is (-3, -4).
