The equation x = 3 represents a vertical line, but not a linear function, as it violates the definition of a function. Thus, the correct choice is D.

The equation x = 3 describes a vertical line passing through the point where x equals 3 on the coordinate plane.

While it represents a line, it fails to meet the criteria of a function because it violates the one-to-one mapping between inputs (x-values) and outputs (y-values).

For every value of x, the y-value remains constant at 3, meaning multiple x-values map to the same y-value, thus failing the vertical line test for functions.

Therefore, although it represents a line, it does not represent a linear function. Thus, the correct choice is D.

Complete Question:

Which statement best describes the equation x = 3?

A. The equation can not be graphed.

B. The equation represents a function, but not a linear function.

C. The equation represents a linear function.

D. The equation represents a line, but not a linear function.

Answer:

2in

Step-by-step explanation:

Let's call the original side "x". so x² (area of a square) is = x² (as we can't simplify it). Then we got a 4 added to each side. So now we redefine each side as "x+4". So now we can make an equation of the area of the square. x² + 4² = 36. Now you realize that 36 is 6² so you write it. x² + 4² = 6² . Since everything is now a square just square root everything (√) So Now x + 4 = 6. Now you have a 1st degree equation now solve simple math. x = 6 - 4 = 2. The side of original square is 2in

Answer:

C.Ralph would save more, since he has $30,000 more in principal

Step-by-step explanation:

The amount of interest each will pay (or save) on his loan is proportional to the amount of principal. Since Ralph's principal of $98000 is more than David's principal of $68000, Ralph will save more by paying off the loan early.

First, let's get out common denominators.

8/12 and 3/12.

We then minus the 8 and 3 = 5/12.

We have 5/12.

Answer:

Step-by-step explanation:

The perimeter is the arc length plus the two radius lines.

Arc length is:

s = (θ/360) 2πr

So the perimeter is:

P = (θ/360) 2πr + 2r

Given that θ=135 and r = 11:

P = (135/360) 2π(11) + 2(11)

P = 8.25π + 22

P ≈ 47.9

So the perimeter is greater than 47.5 cm.

Answer:

The position P is:

[tex]P = 87\^x + 75\^y[/tex] ft     Remember that the position is a vector. Observe the attached image

Step-by-step explanation:

The equation that describes the height as a function of time of an object that moves in a parabolic trajectory with an initial velocity [tex]s_0[/tex] is:

[tex]y(t) = y_0 + s_0t -16t ^ 2[/tex]

Where [tex]y_0[/tex] is the initial height = 0 for this case

We know that the initial velocity is:

82 ft/sec at an angle of 58 ° with respect to the ground.

So:

[tex]s_0 = 82sin(58\°)[/tex] ft/sec

[tex]s_0 = 69.54[/tex] ft/sec

Thus

[tex]y(t) = 69.54t -16t ^ 2[/tex]

The height after 2 sec is:

[tex]y(2) = 69.54 (2) -16 (2) ^ 2[/tex]

[tex]y(2) = 75\ ft[/tex]

Then the equation that describes the horizontal position of the ball is

[tex]X(t) = X_0 + s_0t[/tex]

Where

[tex]X_ 0 = 0[/tex] for this case

[tex]s_0 = 82cos(58\°)[/tex] ft / sec

[tex]s_0 = 43.45[/tex] ft/sec

So

[tex]X(t) = 43.45t[/tex]

After 2 seconds the horizontal distance reached by the ball is:

[tex]X (2) = 43.45(2)\\\\X (2) = 87\ ft[/tex]

Finally the vector position P is:

[tex]P = 87\^x + 75\^y[/tex] ft

Answer:

3 out of 51

Step-by-step explanation:

If he removed one number two card from the deck then there should be three left since there are 4 of each number card in a deck so therefore there should be 51 cards in the deck but only three number two cards left in the deck

The probability of drawing a number two card from a 52-card deck after removing all four number two cards is 0, as there are no such cards left to draw.

Calculating the Probability of Drawing a Number Two Card

If John removes the number two card from a standard 52-card deck, the deck then has 48 cards because there are 4 number two cards, one in each suit (clubs, diamonds, hearts, and spades). Since these cards are no longer in the deck, the probability of picking up a number two card at random from the remaining deck is 0, as there are no number two cards left to draw.

Initially, the probability of drawing a two card from a full deck would be 4 out of 52 cards or 1 out of 13, as there are 4 twos in the set of 52 cards. However, with the removal of all four number twos, there are no such cards left, hence the probability of drawing a two is reduced to 0.

Understanding probability in a deck of cards is a fundamental concept in statistics and probability theory, which can be applied to various practical situations including games and predictive models.

Answer:

[tex]x=4,y=-3[/tex], or as an ordered pair: (4, -3)

Step-by-step explanation:

We have the system of equations

[tex]x^2+y^2=25[/tex] (1)

[tex]x-y^2=-5[/tex] (2)

Let's solve our system step-by-step:

Step 1. Solve for [tex]y^2[/tex] in equation (1)

[tex]x^2+y^2=25[/tex]

[tex]y^2=25-x^2[/tex] (3)

Step 2. Replace equation (3) in equation (2) and solve for [tex]x[/tex]

[tex]x-y^2=-5[/tex]

[tex]x-(25-x^2)=-5[/tex]

[tex]x-25+x^2=-5[/tex]

[tex]x^2+x-20=0[/tex]

[tex](x+5)(x-4)=0[/tex]

[tex]x+5=0,x-4=0[/tex]

[tex]x=-5,x=4[/tex]

Remember that in the fourth quadrant x is positive and y is negative, so we are taking the positive value of x; in other words [tex]x=4[/tex] (4)

Step 3. Replace equation (4) (the positive value of x) in equation (1)

[tex]x^2+y^2=25[/tex]

[tex]4^2+y^2=25[/tex]

[tex]16+y^2=25[/tex]

[tex]y^2=25-16[/tex]

[tex]y^2=9[/tex]

[tex]y=\sqrt{9} ,y=-\sqrt{9}[/tex]

[tex]y=3,y=-3[/tex]

Since y is negative in quadrant IV, we take [tex]y=-3[/tex]

We can conclude that the solution of our system of equations that lies in the quadrant IV is [tex]x=4,y=-3[/tex], or as an ordered pair: (4, -3)

The binomial expansion of (x²+y²)² is x⁴ +y⁴ + 2x²y²

The theorem states that any power of a binomial (a + b)ⁿ can be expanded as a specific sum of products (), such as (a + b)² = a² + 2ab + b².

Given

The given expression is (x² + y²)² and we have to simplify it to find the binomial expansion.

(x ²+ y²)² is in the form of (a + b)².

When we expand (a + b)² we get the binomial expression

(a + b)² = a² + b² + 2ab

Now we put the value of a = x² and b = y²

(x² + y²)² = (x²)² + (y²)² + 2(x²)(y²)

              = x⁴ + y⁴ + 2x²y²

Answer:

[tex]A=34\ units^2[/tex]

Step-by-step explanation:

Suppose we have a general triangle like the one shown in the figure.

We know the angle A, the angle B and the length b.

[tex]A = 30\°\\\\B = 45\°\\\\b = 10[/tex]

By definition I know that the sum of the internal angles of a triangle is always equal to 180 °.

So

[tex]A + B + C = 180\\\\30 + 45 + C = 180[/tex]

We solve the equation and thus we find the angle C.

[tex]C = 180 - 30-45\\\\C = 105[/tex]

We already know the three triangle angles.

Now we use the sine theorem to calculate the sides c and a.

The  sine theorem says that:

[tex]\frac{sin(A)}{a}=\frac{sin(B)}{b}=\frac{sin(C)}{c}[/tex]

Then

[tex]\frac{sin(30)}{a}=\frac{sin(45)}{10}[/tex]

[tex]\frac{sin(30)}{\frac{sin(45)}{10}}=a[/tex]

[tex]a=7.071[/tex]

Also

[tex]\frac{sin(105)}{c}=\frac{sin(45)}{10}[/tex]

[tex]\frac{sin(105)}{\frac{sin(45)}{10}}=c[/tex]

[tex]c=13.660[/tex]

Finally, we use the Heron formula to calculate the triangle area

[tex]A=\sqrt{s(s-a)(s-b)(s-c)}[/tex]

Where s is:

[tex]s=\frac{a+b+c}{2}[/tex]

Therefore

[tex]s=\frac{7.071+10+13.660}{2}[/tex]

[tex]s=15.37[/tex]

[tex]A=\sqrt{15.37(15.37-7.071)(15.37-10)(15.37-13.66)}[/tex]

Answer:

5

Step-by-step explanation:

Given a complex number x + yi then the conjugate is x - yi

Note the real part remains unchanged while the sign of the imaginary part is negated.

here z = 1 - 2i hence conjugate is 1 + 2i

and the product is

(1 - 2i)(1 + 2i) ← expand factors

= 1 - 4i² [ i² = - 1 ]

= 1 + 4

= 5

The product of z and its conjugate will be 5.

The complex number is the combination of the real part and the imaginary part. Then the complex number is given as

⇒ a+bi

In the graph, z is a complex number represented as a vector from the origin.

Then the complex number will be

z = 1 – 2i

Then the conjugate of z will be

⇒ 1 + 2i

Then the product of z and its conjugate will be

⇒ (1 – 2i)(1 + 2i)

⇒ 1² – 2²i²

We know i² = -1

⇒ 1 – 4(-1)

⇒ 1 + 4

⇒ 1² – 2²i²

⇒ 5

a = 70°

Step-by-step explanation:

a and 110 form a straight angle, thus

a + 110 = 180 ( subtract 110 from both sides )

a = 70°

Answer:

a =70

Step-by-step explanation:

Angle a and 110 are supplementary, which means they add to 180 degrees

a+ 110 = 180

Subtract 110 from each side

a+110-100=180-110

a = 70

To simplify 4(6r+3) + 2(r + 2), distribute the coefficients, combine like terms, resulting in the simplified expression 26r + 16.

To simplify the expression 4(6r+3) + 2(r + 2), we need to distribute the multiplication over the addition inside the parentheses and then combine like terms.

Distribute the 4 into the first set of parentheses: 4 × 6r = 24r and 4 × 3 = 12.

Do the same with the 2 into the second set of parentheses: 2 × r = 2r and 2 × 2 = 4.

Now, combine the individual terms: The expression becomes 24r + 12 + 2r + 4.

Combine like terms (24r and 2r) and constants (12 and 4): 24r + 2r = 26r and 12 + 4 = 16.

The simplified expression is therefore 26r + 16.
