The two values for x so the points form a right triangle are x = -4 and x = 10

From the question, we have the following parameters that can be used in our computation:

The coordinates of the points are A(5,3), B(5,6) and C(x,3).

The third point is given as

C(x,3)

The value of x can be any real value apart from 5

This is because if x = 5, then it would be the same as point A

So, we can use the following values for x

x = -4 and x = 10

Note that all real values work for x

Answer:

2m=7. m=7/2. 10x =48. x = 4.8

Step-by-step explanation:

2m

Answer:

a)  7/2 or 3.5

b) 4.8

form equation and solve them

a}n = 17

Step-by-step explanation:

a) 2m + 8 = 15

Subtract 8 from both sides: 2m + 8 - 8 = 15 - 8

Simplify: 2m = 7

Divide both sides by 2: (2m)/2 = 7/2

Simplify: m = 7/2 or 3.5

b) 10x - 3 = 45

Add 3 to both sides: 10x - 3 + 3 = 45 + 3

Simplify: 10x = 48

Divide both sides by 10: (10x)/10 = 48/10

Simplify: x = 4.8

To form and solve an equation for Ashley’s problem, we need to translate the words into mathematical expressions. Here are the steps and solution:

a) Ashley thinks of a number if i double my number and add 6 the answer is 40

Let n be Ashley’s number.

If we double the number, we get 2n.

If we add 6 to the doubled number, we get 2n + 6.

The answer is equal to 40, so we can write an equation: 2n + 6 = 40

To solve for n, we need to isolate it on one side of the equation by using inverse operations.

Subtract 6 from both sides: 2n + 6 - 6 = 40 - 6

Simplify: 2n = 34

Divide both sides by 2: (2n)/2 = 34/2

Simplify: n = 17

The total number of ways to arrange all 6 tables is 720

There are 15 ways to choose 4 tables out of 6.

(a) There are 6 options for the first table, 5 options left for the second table, 4 options left for the third table, and so on.

Therefore, the total number of ways to arrange all 6 tables is:

6 x 5 x 4 x 3 x 2 x 1 = 720

(b) To choose 4 tables out of 6, we can use the combination formula:

C(6,4) = 6! / (4! x 2!)

The quadratic function f(x) = 2x² - 5x + 3, it is found :

a. The factored function is, f(x) = 2(x - 1)(x - 1.5).

b. The x-intercepts of the function are: x = 1, x = 1.5.

c. The end behavior of the graph is:

As x -> -∞, f(x) -> -∞.

As x -> ∞, f(x) -> ∞.

The quadratic function is :

f(x) = 2x² - 5x + 3.

Hence the coefficients are:

a = 2, b = -5, c = 3.

Using a calculator with these coefficients, the x-intercepts are:

x = 1.

x = 1.5.

Then the factored form of the function;

f(x) = 2(x - 1)(x - 1.5).

Let the leading coefficient of 2 and the x-intercepts.

This is a concave-up parabola, it goes to positive infinity to the left and to the right of the graph.

Hence the end behavior is;

As x -> -∞, f(x) -> -∞.

As x -> ∞, f(x) -> ∞.

To determine the graph, the axis of symmetry is:

x = -b/2a = 5/(2(2)) = 1.25.

The y-coordinate at this point, that is the turning point of the function, is:

f(1.25) = 2(1.25)² - 5(1.25) + 3 = -0.125.

The y-intercept of the function

f(0) = 2(0)² - 5(0) + 3 = 3.

The surface area of the box increases by 67.26 cm² when the height is increased by 0.7 cm.

Recall the formula, Surface Area (SA) of the rectangular prism is given as:

SA = 2lw + 2lh + 2wh

where

l = length,

w = width,

h =  height

From the diagram, we know that:

l = 18cm

w = 6.3cm

h = 30cm

Substituting these values into the surface area formula, we get:

SA₁ = 2(18)(6.3) + 2(18)(30) + 2(6.3)(30) = 2376 cm²

When the height is increased by 0.7cm, the new height becomes:

h' = h + 0.7cm = 30.7cm

The new surface area can be calculated using the same formula:

SA₂ = 2(18)(6.3) + 2(18)(30.7) + 2(6.3)(30.7) = 2443.26 cm²

The increase in surface area is the difference between the new surface area and the original surface area:

We can use the formula for estimating population proportion:

Population proportion = sample proportion x population size

where the sample proportion is the fraction of students in the sample who are Art majors, and the population size is the total number of students in the population.

From the sample of 250 students, 75 said that they are majoring in Art, so the sample proportion of Art majors.

sample proportion = 75/250 = 0.3

The population size is 7,500 students.

Using the formula above, we can estimate the number of Art majors in the total population:

The solution of the differential equation y'' + 2y' - y = xe is found to be [tex]y = Ce^{(-1-\frac{\sqrt{6}}{2})t} + C'e^{(-1+\frac{\sqrt{6}}{2})t} - \frac{4}{3}xe^{x} + Ce^{x}[/tex]

To solve the differential equation y'' + 2y' - y = xeˣ, we first find the complementary solution by solving the characteristic equation,

r² + 2r - 1 = 0

Using the quadratic formula, we get,

r = (-2 ± √(2² + 4(1)(1))) / 2

r = (-2 ± √6) / 2

So the roots are,

r₁ = -1 - √6/2

r₂ = -1 + √6/2

Therefore, the complementary solution is:

[tex]y_c = Ce^{r_{1}t} + C'e^{r_{2}t}\\y = Ce^{(-1-\frac{\sqrt{6}}{2})t} + C'e^{(-1+\frac{\sqrt{6}}{2})t}[/tex]

To find the particular solution, we use the method of undetermined coefficients. We assume a particular solution of the form,

y_p = Ax²eˣ + Bxeˣ + Ceˣ

Taking the first and second derivatives, we get,

y'_p = (2Ax + B + A)x eˣ + Beˣ + Ceˣ

y''_p = (4A + 2Ax + B + A)x eˣ + (2A + B)eˣ + Ceˣ

Substituting these expressions into the differential equation, we get,

(4A + 2Ax + B + A)x eˣ + (2A + B)eˣ + Ceˣ + 2[(2Ax + B + A)x eˣ + Beˣ + Ceˣ] - (Ax²eˣ + Bxeˣ + Ceˣ) = xeˣ

Simplifying, we get,

(3Ax² + 4Ax + B)x eˣ = xeˣ

Equating coefficients, we get,

3A = 1

4A + B = 0

Solving for A and B, we get,

A = 1/3

B = -4/3

Substituting these values into the assumed particular solution, we get,

y_p = (1/3)x²eˣ - (4/3)xeˣ + Ceˣ

Taking the first and second derivatives, we get,

y'_p = (2/3)x eˣ - 4/3eˣ + Ceˣ

y''_p = (2/3)eˣ + Ceˣ

Substituting the particular solution and its derivatives into the differential equation and simplifying, We get,

(2/3)xeˣ = xeˣ

This equation is true for all x, so there is no restriction on C. Therefore, the general solution is,

y = y_c + y_p

[tex]y = Ce^{(-1-\frac{\sqrt{6}}{2})t} + C'e^{(-1+\frac{\sqrt{6}}{2})t} - \frac{4}{3}xe^{x} + Ce^{x}[/tex]

```

r | \ x

|_ _\

s

```

Using the Pythagorean theorem, we can write:

r^2 = x^2 + s^2

Rearranging this equation, we get:

x^2 = r^2 - s^2

Subtracting r^2 from both sides, we get:

x^2 - r^2 = -s^2

Multiplying both sides by -1, we get:

s^2 - x^2 = 0

Therefore, the equation for the relationship between the two radii is:

s^2 - x^2 = 0

Simplifying this equation, we get:

s^2 = x^2

or

x^2 = s^2

So, there is a zero on one side of the equals sign.

We can expect a student to guess 17 correct answers on a test with 68 four-choice multiple choice questions with probability 0.25.

Since the probability of guessing the correct answer to a four-choice multiple choice question is 0.25, the probability of guessing an incorrect answer is 1 - 0.25 = 0.75.

We can model the number of correct guesses as a binomial distribution with n = 68 (the number of trials) and p = 0.25 (the probability of success, i.e., guessing correctly).

The expected value of a binomial distribution is given by the formula:

Step-by-step explanation:

It is 90° angle so their sum must be 90°( complement) .

3x + 5° + 37° = 90°

3x + 42° = 90° ... simplify the like term

3x = 90° - 42°

(10x - 15) ≥ 10*(5/2)

10x - 15 ≥ 25

Now add 15 in both sides:

10x ≥ 25 + 15

30 gallons of 28% butterfat and 30 gallons of 16% butterfat should be combined to create a 60-gallon mixture that is 22 % butterfat.

Let x gallon of 28% butterfat mixed with the y gallon of 16% butterfat to obtain 60 gallons of 22.5% butterfat,

⇒ x + y = 60 ⇒ x = 60 - y ----(1),

Quantity of butterfat in x gallon + quantity of butterfat in y gallon = total quantity of butterfat,

⇒ 28% of x + 16% of y = 22% of 60

⇒ 0.28x + 0.16y = 0.22 × 60

⇒ 0.28x + 0.16y = 13.2

⇒ 28x + 16y = 1320

⇒ 14x + 8y = 660

From equation (1),

14(60-y) + 8y = 660

840 - 14y + 8y = 660

6y = 180

y = 30

Again from equation (1),

x = 60 - y

= 60 - 30

= 30

Hence, 30 gallons of 28% butterfat and 30 gallons of 16% butterfat are combined to create a 60-gallon mixture that is 22%
