Part 1) Vertical line : [tex]x=1[/tex]

Part 2) Horizontal line :  [tex]y=-4[/tex]

Step-by-step explanation:

Part 1) Write the equation for the vertical line passing through the point (1,-4)

we know that

The equation of a vertical line (parallel to the y-axis) is equal to the x-coordinate of the point that passes through it

so

The x-coordinate is 1

therefore

The equation of the line is

[tex]x=1[/tex]

Part 2) Write the equation for the horizontal line passing through the point (1,-4)

we know that

The equation of a horizontal line (parallel to the x-axis) is equal to the y-coordinate of the point that passes through it

so

The y-coordinate is -4

therefore

The equation of the line is

[tex]y=-4[/tex]

Step-by-step explanation:

its 20 and a half because 16+20=36 and you just need to add a half to 20 since your taking it away

Answer:

c=20.5 or 41/2

Step-by-step explanation:

c- 1/2 + 16=36

Make C the subject

c=36-16+1/2

c=20+1/2

Using LCM

c=(40+1)/2

c=41/2

c=20.5

To check if we are correct, we substitute c with 41/2. and then both sides of the equation must be equal

c- 1/2 + 16=36

41/2-1/2+16=36

20+16=36

36=36

Answer:

Here the degree of the polynomial is 11.

Step-by-step explanation:

To find the degree of the multivariate polynomials, we need to add up the powers of all the variables.   So the total degree is given by the sum of all the powers of the highest powers terms.

Now in the given polynomial [tex]-3w+x^6y^5-2+5y^4w^3x^2[/tex]

the term with the highest total powers is [tex]x^6y^5[/tex] and thus the total power is 6+5=11.

And hence the degree of this polynomial is 11.

The cost of one hot dog is $1.75

The cost of one hamburger is $1.5

Step-by-step explanation:

Let,

The equations can be formed as :

7x + 4y = 18.25  --------(1)

4x + 7y = 17.50  --------(2)

Multiply eq (1) by 4 and eq (2) by 7,

   28x + 16y = 73

- (28x + 49y = 122.5)

         - 33y = - 49.5

y = 49.5/33

y = 1.5

The cost of one hamburger is $1.5

Substitute y=1.5 in eq (1),

7x + 4(1.5) = 18.25

7x = 18.25 - 6

x = 12.25/7

x = 1.75

The cost of one hot dog is $1.75

Answer:

D(4) = -18

Step-by-step explanation:

D(n) = D(n – 1)(-6)

D(1) = 1/12

D(2) = D(2 – 1)(-6)

D(2) = D(1)(-6)

D(2) = 1/12 * (-6)

D(2) = -6/12

D(2) = -1/2

D(3) = D(3 – 1)(-6)

D(3) = D(2)(-6)

D(3) = -1/2 * (-6)

D(3) = 6/2

D(3) = 3

D(4) = D(4 – 1)(-6)

D(4) = D(3)(-6)

D(4) = 3 * (-6)

D(4) = -18

Answer: 30 min.

Step-by-step explanation: for this, you have to find the gcf of 5 and 6, which is 30.

Final answer:

Mike and Sam will both cross the starting line together after 30 minutes of running, as 30 minutes is the least common multiple of their individual lap times of 5 and 6 minutes.

Explanation:

To find out how long it will take for Mike and Sam to cross the starting line together again, we need to determine the least common multiple (LCM) of their lap times. Mike runs a lap in 5 minutes and Sam runs a lap in 6 minutes. The LCM of 5 and 6 will give us the first time they both cross the starting line at the same time after they start running.

To calculate the LCM of 5 and 6, we list the multiples of each number until we find a common one:

5, 10, 15, 20, 25, 30, ...

6, 12, 18, 24, 30, ...

The smallest common multiple of 5 and 6 is 30. Therefore, Mike and Sam will both cross the starting line together after 30 minutes of running.

To determine the length of ZY for it to be a tangent to circle X at point Y, we must know additional measurements, such as the radius of the circle, because a tangent is perpendicular to the radius at the point of tangency.

To determine the length of ZY so that it is tangent to circle X at point Y, we need to apply properties of tangents to a circle. A tangent to a circle forms a right angle with the radius at the point of tangency. Therefore, in a right-angled triangle, with the radius XY being one side and ZY being the hypotenuse, we could use the Pythagorean theorem if we know the length of the radius and any other segment connected to the radius or tangent.

Without further information, such as the length of radius XY or any other segment, it's not possible to calculate the exact length of ZY. However, the essential condition is that radius XY must be perpendicular to the tangent ZY at point Y for ZY to be a proper tangent.

The average value of f(x) = 3x sin(x) on the interval [tex]\( 1 \leq x \leq 7 \) is approximately \( -1.6204 \).[/tex]

To find the average value of a function f(x) on a closed interval [a, b], we use the formula:

[tex]\[ \text{Average value} = \frac{1}{b - a} \int_{a}^{b} f(x) \, dx \]In this case, the function \( f(x) = 3x \sin(x) \) and the closed interval is \( 1 \leq x \leq 7 \).So, the average value of \( f(x) \) on the interval \( 1 \leq x \leq 7 \) is:\[ \text{Average value} = \frac{1}{7 - 1} \int_{1}^{7} 3x \sin(x) \, dx \][/tex]

[tex]\[ \text{Average value} = \frac{1}{6} \int_{1}^{7} 3x \sin(x) \, dx \][/tex]

Now, we need to compute the integral. We can do this using integration by parts:

[tex]Let \( u = 3x \) and \( dv = \sin(x) \, dx \).Then, \( du = 3 \, dx \) and \( v = -\cos(x) \).Using the integration by parts formula:\[ \int u \, dv = uv - \int v \, du \]\[ \int_{1}^{7} 3x \sin(x) \, dx = \left[ -3x \cos(x) \right]_{1}^{7} - \int_{1}^{7} (-\cos(x)) \cdot 3 \, dx \][/tex]

[tex]\[ = \left[ -3x \cos(x) \right]_{1}^{7} + 3 \int_{1}^{7} \cos(x) \, dx \]\[ = \left[ -3x \cos(x) \right]_{1}^{7} + 3 \left[ \sin(x) \right]_{1}^{7} \]\[ = \left[ -21 \cos(7) + 3 \sin(7) \right] - \left[ -3 \cos(1) + 3 \sin(1) \right] \][/tex]

Now, let's compute these values:

[tex]\[ \text{Average value} = \frac{1}{6} \left[ \left( -21 \cos(7) + 3 \sin(7) \right) - \left( -3 \cos(1) + 3 \sin(1) \right) \right] \]\[ \text{Average value} = \frac{1}{6} \left[ (-21 \times 0.7539 + 3 \times 0.6560) - (-3 \times 0.5403 + 3 \times 0.8415) \right] \]\[ \text{Average value} = \frac{1}{6} \left[ (-15.8359 + 1.9680) - (-1.6209 + 2.5245) \right] \][/tex]

[tex]\[ \text{Average value} = \frac{1}{6} \left[ -13.8679 + 4.1454 \right] \]\[ \text{Average value} = \frac{1}{6} \times (-9.7225) \]\[ \text{Average value} \approx -1.6204 \][/tex]

So, the average value of f(x) = 3x sin(x) on the interval [tex]\( 1 \leq x \leq 7 \) is approximately \( -1.6204 \).[/tex]

The average value of [tex]\(f(x) = 3x \sin(x)\)[/tex] on the interval [tex]\(1 \leq x \leq 7\)[/tex] is approximately 1.879.

To find the average value of [tex]\( f(x) = 3x \sin(x) \)[/tex]on the closed interval [tex]\( 1 \leq x \leq 7 \)[/tex], we can use the formula for the average value of a function on a closed interval [a, b] :

[tex]\[ \text{Average value} = \frac{1}{b - a} \int_a^b f(x) \, dx \][/tex]

In this case, a = 1 and b = 7, so:

[tex]\[ \text{Average value} = \frac{1}{7 - 1} \int_1^7 3x \sin(x) \, dx \][/tex]

Now, we need to evaluate the integral:

[tex]\[ \int_1^7 3x \sin(x) \, dx \][/tex]

This integral can be evaluated using integration by parts or by using a software tool. After evaluation, we find that the average value is approximately 1.879.

So, the correct answer is 1.879.

Answer:

10 bows

Step-by-step explanation:

Each bow is 0.5 yards and you have 5 yards of ribbon. In equation form (where x = number of bows), that looks like: 0.5 * x = 5. Solve for x and you'll get x = 10.

This mathematics problem can be solved by multiplication. Since each bow requires half a yard of ribbon, each yard can produce two bows. Therefore, five yards of ribbon can produce 10 bows.

The question requires us to determine how many bows we can make with a given number of yards of ribbon. Since it takes half a yard of ribbon to make a bow, you can fit two bows in a single yard. To find how many bows can be made with 5 yards, you can perform multiplication.

To do this, you would multiply the number of yards by 2, since each yard can create two bows: 5 yards × 2 = 10 bows. So, you can make 10 bows out of 5 yards of ribbon.

Order is impotant since you could easily make a positve number negative and vice versa. You switch the order of 5 subtracted by y to y-5.

The length of the rectangle is 11 units

The width of the rectangle is 5 units.

Explanation:

The equation of the trinomial is [tex]r^{2}-6 r-55[/tex]

We need to find the length and the width of the rectangle.

The length and width of the rectangle can be determined by factoring the trinomial [tex]r^{2}-6 r-55=0[/tex]

Factoring using the quadratic formula, we have,

[tex]x=\frac{-b \pm \sqrt{b^{2}-4 a c}}{2 a}[/tex]

where [tex]a=1, b=-6[/tex] and [tex]c=-55[/tex]

Substituting these in the above formula, we have,

[tex]r=\frac{-(-6) \pm \sqrt{(-6)^{2}-4 \cdot 1(-55)}}{2 \cdot 1}[/tex]

[tex]r=\frac{6\pm \sqrt{36+220}}{2}[/tex]

[tex]r=\frac{6\pm \sqrt{256}}{2}[/tex]

[tex]r=\frac{6\pm 16}{2}[/tex]

Hence, the two roots of the trinomial are

[tex]r=\frac{6+ 16}{2}[/tex] and [tex]r=\frac{6- 16}{2}[/tex]

Solving [tex]r=\frac{6+ 16}{2}[/tex] , we get,

[tex]r=\frac{22}{2}[/tex]

[tex]r=11[/tex]

Solving [tex]r=\frac{6- 16}{2}[/tex] , we get,

[tex]r=\frac{-10}{2}[/tex]

[tex]r=-5[/tex]

Thus, the solutions of the trinomial are 11 and -5

Since, the length of the rectangle is larger than the width, the length of the rectangle is 11 units.

Also, the width of the rectangle cannot be negative.

Thus, ignoring the negative sign, we have, [tex]r=5[/tex]

Hence, the width of the rectangle is 5 units.

Well, there can be three different steps.

Rearrange the equation so "y" is on the left and everything else on the right.

Plot the "y=" line (make it a solid line for y≤ or y≥, and a dashed line for y< or y>)

Shade above the line for a "greater than" (y> or y≥) or below the line for a "less than" (y< or y≤).

Final answer:

To find the value of x, set the two expressions for the lengths of the sides of the rectangle equal to each other and solve. The value of x is 2. To find the length of each diagonal, use the Pythagorean Theorem with the lengths of the sides of the rectangle. The length of each diagonal is 13 * sqrt(2).

Explanation:

To find the value of x, we can set the two expressions for the lengths of the sides of the rectangle equal to each other, since opposite sides of a rectangle are congruent. So, we have:

6x + 1 = 9x - 5

To solve for x, we can subtract 9x from both sides and add 5 to both sides:

1 + 5 = 9x - 6x

6 = 3x

x = 2

Therefore, the value of x is 2. To find the length of each diagonal, we can use the Pythagorean Theorem. The diagonal of a rectangle acts as the hypotenuse of a right triangle formed by the sides of the rectangle. In this case, the length of one side is 6x + 1, and the length of the other side is 9x - 5. So, the length of each diagonal is:

d = sqrt((6x + 1)^2 + (9x - 5)^2)

d = sqrt((6(2) + 1)^2 + (9(2) - 5)^2)

d = sqrt(13^2 + 13^2)

d = sqrt(2 * 13^2)

d = 13 * sqrt(2)
