Answer:

yes, (1,6) is a solution to the inequality y<4x+2.

Step-by-step explanation:

Looking at the equation we can see that the slope is 4 and the y intercept is 2.

Now we will use the slope that is comprised of the rise over the run which is \(\frac{rise}{run}\)

The slope is 4 this means that \(\frac{rise}{run}\) = \(\frac{4}{1}\) and this shows us that the rise is 4 and the run is 1, so starting at (0,2) you go up 4 and over 1 so our next coordinate would be (1,6)

so the answer is yes, (1,6) is a solution to the inequality y<4x+2.

Hope this helps!

Answer:

y = -0.6x + 24.6

Step-by-step explanation:

The general solution to the differential equation dy/dx = 1/3(sin x − xy^2), y(0)=5 is: y = ±√[(sin x - e^(x/2)/25)/x], if sin x - xy^2 > 0 and y(0) = 5

To solve this differential equation, we can use separation of variables.

First, we can rearrange the equation to get dy/dx on one side and the rest on the other side:

dy/dx = 1/3(sin x − xy^2)

dy/(sin x - xy^2) = dx/3

Now we can integrate both sides:

∫dy/(sin x - xy^2) = ∫dx/3

To integrate the left side, we can use substitution. Let u = xy^2, then du/dx = y^2 + 2xy(dy/dx). Substituting these expressions into the left side gives:

∫dy/(sin x - xy^2) = ∫du/(sin x - u)

= -1/2∫d(cos x - u/sin x)

= -1/2 ln|sin x - xy^2| + C1

For the right side, we simply integrate with respect to x:

∫dx/3 = x/3 + C2

Putting these together, we get:

-1/2 ln|sin x - xy^2| = x/3 + C

To solve for y, we can exponentiate both sides:

|sin x - xy^2|^-1/2 = e^(2C/3 - x/3)

|sin x - xy^2| = 1/e^(2C/3 - x/3)

Since the absolute value of sin x - xy^2 can be either positive or negative, we need to consider both cases.

Case 1: sin x - xy^2 > 0

In this case, we have:

sin x - xy^2 = 1/e^(2C/3 - x/3)

Solving for y, we get:

y = ±√[(sin x - 1/e^(2C/3 - x/3))/x]

Note that the initial condition y(0) = 5 only applies to the positive square root. We can use this condition to solve for C:

y(0) = √(sin 0 - 1/e^(2C/3)) = √(0 - 1/e^(2C/3)) = 5

Squaring both sides and solving for C, we get:

C = 3/2 ln(1/25)

Putting this value of C back into the expression for y, we get:

y = √[(sin x - e^(x/2)/25)/x]

Case 2: sin x - xy^2 < 0

In this case, we have:

- sin x + xy^2 = 1/e^(2C/3 - x/3)

Solving for y, we get:

y = ±√[(e^(2C/3 - x/3) - sin x)/x]

Again, using the initial condition y(0) = 5 and solving for C, we get:

C = 3/2 ln(1/25) + 2/3 ln(5)

Putting this value of C back into the expression for y, we get:

y = -√[(e^(2/3 ln 5 - x/3) - sin x)/x]

So the general solution to the differential equation dy/dx = 1/3(sin x − xy^2), y(0)=5 is:

y = ±√[(sin x - e^(x/2)/25)/x], if sin x - xy^2 > 0 and y(0) = 5

y = -√[(e^(2/3 ln 5 - x/3) - sin x)/x], if sin x - xy^2 < 0 and y(0) = 5

Note that there is no solution for y when sin x - xy^2 = 0.

The length of AC cannot be determined based on the information provided.

The confusion earlier.

Given the information that Triangle ABC has a perimeter of 40 inches, we can proceed to find the length of AC.

Let's assume that AC has a length of x inches.

Since the perimeter of a triangle is the sum of the lengths of its sides, we can set up an equation:

AC + AB + BC = 40

Substituting the values in the equation, we have:

x + AB + BC = 40

Without any additional information or specific lengths for AB and BC, it is not possible to determine the exact value of x or AC.

The lengths of AB and BC could vary, resulting in different values for AC.

We can go on to find the length of AC now that we know Triangle ABC has a perimeter of 40 inches.

Assume for the moment that AC is x inches long.

We may create the equation AC + AB + BC = 40 since the perimeter of a triangle is equal to the sum of the lengths of its sides.

With the variables in the equation substituted, we get x + AB + BC = 40.

As per unitary method, the amount it will cost to fill the pool is $2.68

The Unitary Method is a mathematical concept which encourages students to use one single rule or principle to solve a problem. It can be used to solve a variety of mathematical problems in algebra, geometry, and other areas.

In this case, the pool is 10 ft wide. To calculate the capacity of a pool with a rectangular shape, you need to multiply its width by its length and then multiply that result by its depth.

If we assume that the length and depth of the pool are both equal to 10 ft, then the capacity of the pool can be calculated as follows:

=> 10 ft x 10 ft x 10 ft = 1,000 cubic feet.

To convert the capacity to gallons, you need to divide

=> 1,000  / 7.48 = 133.89

gallons of water required to fill the pool.

Finally, to calculate the cost of filling the pool, you just need to multiply the number of gallons by the cost per gallon of water ($0.02).

=> 133.89 x 0.02 = 2.68

This gives us a total cost of $2.68 to fill the pool with water.

The second ladder touches the wall approximately 11 feet higher than the shorter ladder, or equivalently, around 8 feet 8 inches higher.

Let's denote the height at which the second ladder touches the wall as h. We can set up a proportion based on the similar right triangles formed by the ladders and the building:

(6 6 feet) / (h) = (9 9 feet) / (5 5 feet 9 9 inches + h)

To solve for h, we can cross-multiply and solve the resulting equation:

(6 6 feet) * (5 5 feet 9 9 inches + h) = (9 9 feet) * (h)

Converting the measurements to inches:

(66 inches) * (66 inches + h) = (99 inches) * (h)

Expanding and rearranging the equation:

4356 + 66h = 99h

33h = 4356

Solving for h:

h = 4356 / 33 = 132 inches

Converting back to feet and inches:

h ≈ 11 feet

Therefore, the second ladder touches the wall approximately 11 feet higher than the shorter ladder, or equivalently, around 8 feet 8 inches higher.

Step-by-step explanation:

The  correct answer for the interval equivalent to 27 is [-7, 13].

To find the interval equivalent to 27, we need to determine the range of values for r and t that satisfy the given conditions.

The inequality we have is: |2t - 4r - 6| ≤ 20

Let's consider two cases:

Case 1: (2t - 4r - 6) ≥ 0

Simplifying the inequality, we have: 2t - 4r - 6 ≤ 20

Adding 6 to both sides: 2t - 4r ≤ 26

Dividing by 2: t - 2r ≤ 13

Case 2: (2t - 4r - 6) < 0

Simplifying the inequality, we have: -(2t - 4r - 6) ≤ 20

Expanding the inequality: -2t + 4r + 6 ≤ 20

Subtracting 6 from both sides: -2t + 4r ≤ 14

Dividing by -2 (and reversing the inequality): t - 2r ≥ -7

Now we have the following system of inequalities:

t - 2r ≤ 13

t - 2r ≥ -7

To find the region of overlap, we can graph these two inequalities and determine the common interval.

Plotting the lines t - 2r = 13 and t - 2r = -7, we find that they intersect at the point (3, -1). This point represents the lower limit of the interval.

The upper limit of the interval can be found by substituting r = 0 into the inequalities:

t ≤ 13 (from t - 2r ≤ 13)

t ≥ -7 (from t - 2r ≥ -7)

Therefore, the interval equivalent to 27 is [-7, 13].

y = -2x + 11

Step-by-step explanation:

When two lines are parallel, their gradients are the same. So the gradient of the line parallel to this equation will be -2 as well.

Now we substitute values from this point to find the rest of the equation :

y = -2x + c

3 = -2(4) + c

3 = -8 + c  

c = 11

Answer:

Step-by-step explanation:

1.)

I solved for the vertex. Because the leading coefficient was negative, I knew the graph had to be concave down. This means that the vertex will give me the maximum value.

2.)

I think that graphing is a good way to visualize the graph. When you graph the line, it's easy to see where the vertex as well as the x and y intercept lies.

3.)

The shape they take depends on the leading coefficient. If it's negative, then the graph will be concave down and the vertex will be the maximum value of the graph. If the leading coefficient is positive, then the graph will be concave up and the vertex will be the minimum value of the line.

Answer:

The surface area of the cylinder is 276.32m²

Step-by-step explanation:

To solve this problem we have to calculate the circle area and the lateral area

To calculate the area of ​​the circle we use the following formula

a = area

r = radius = 2m

π = 3.14

a = π * r²

we replace with the known values

a = 3.14 * (2m)²

a = 3.14 * 4m²

a = 12.56m²

The area of the circle is 12.56m²

To calculate the lateral area of ​​the cylinder we use the following formula

a = area  =

h = heighti = 20m

r = radius = 2m

π = 3.14

a = 2 * π * r * h

we replace with the known values

a = 2 * 3.14 * 2m * 20m

a = 6.28 * 40m²

a = 251.2m²

The lateral area of ​​the cylinder is 251.2m²

Now we add the lateral area of ​​the cylinder with 2 times the area of ​​the circle and obtain the area of ​​the cylinder

251.2m²  + (2 * 12.56m²) = 276.32m²

The surface area of the cylinder is 276.32m²
