Answer:

10.8

Step-by-step explanation:

AB can be calculated using the formula [tex] d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2} [/tex]

The coordinates of A are when x = -2, y = -2

At B, x = 8, y = -6

Let,

[tex] A(-2, -2) = (x_1, y_1) [/tex]

[tex] B(8, -6) = (x_2, y_2) [/tex]

Plug the values into the formula.

[tex] AB = \sqrt{(8 - (-2))^2 + (-6 -(-2))^2} [/tex]

[tex] AB = \sqrt{(8 + 2)^2 + (-6 + 2)^2} [/tex]

Answer: Is A in the correct answer

Step-by-step explanation:

The line perpendicular to the line y=2x/3 is Option A) -3x/2+2

Linear equations help in representing the relationship between variables such as x, y, and z, and are expressed in exponents of one degree. In these linear equations, we use algebra, starting from the basics such as the addition and subtraction of algebraic expressions.

Given here, the line passes through the points (0,-1) and (3/2,0)

Thus using the two point form we get the equation of the line as

y=2x/3 +1 with slope =2/3

And in option 1 we have y=-3x/2 + 2 with slope = -3/2 and thus the product of the slopes of the two lines is -3/2 × 2/3 = -1

∴y=2x/3 +1 and  y=-3x/2 + 2 are perpendicular.

Hence, The two lines are perpendicular and option A is the correct option.

Answer:

(12,-6)

Step-by-step explanation:

Answer:

(12,-6)

Step-by-step explanation:

When dilating points, you multiply both coordinates (x and y) by the scale factor.

The point we are given is: (4,-2) and the scale factor is 3.

Multiply each coordinate by the scale factor of 3.

X-coordinate: 4

     4* 3= 12

New X-coordinate: 12

Y-coordinate : -2

    -2 * 3= -6

New Y-coordinate: -6

Our new x-coordinate is 12 and y-coordinate is -6. Therefore, our point is (12,-6). So, the image of point (4,-2) after a dilation of 3 is (12, -6).

Step-by-step explanation:

Given that,

The diameter of the base of a circular cone, d = 18 inches

Height of the cone, h = 40 inches

We need to find the lateral surface area of the cone. The formula of the lateral surface of the cone is given by :

[tex]A=\pi rl[/tex]

l is the slant height of the cone,

[tex]l=\sqrt{r^2+h^2} \\\\l=\sqrt{(9)^2+(40)^2} \\\\l=41\ \text{inches}[/tex], d = 18 inches, r = 9 inches

So,

Answer:

The opposite of integer 4 units away from -6 is 10.

Step-by-step explanation:

We know that the opposite of the opposite of a number, say 2, is the number itself.

That is:

Opposite of 2 is -2.

Then the opposite of -2 is:

- (-2) = 2

Now consider a number line.

The number that is 4 units away from -6 is -10.

So, the number is -10.

The opposite of -10 will be:

- (-10) = 10

Thus, the opposite of integer 4 units away from -6 is 10.

Answer:

Approximately 18.0.

Step-by-step explanation:

To find x, we can use the Law of Cosines.

The Law of Cosines is the following:

[tex]c^2=a^2+b^2-2ab\cos(C)[/tex]

Now that the c is the side we're trying to find. Thus, the c is x. Also, Angle C is the angle opposite to c (or x). a and b are the two sides next to Angle C.

Plug in x for c, 16 for a, 30 for b, and 30 for Angle C:

[tex]x^2=(16)^2+(30)^2-2(16)(30)\cos(30)\\x^2=1156-960\cos(30)\\x=\sqrt{1156-960\cos(30)} \\x\approx18.0171[/tex]

Answer: D) phone calls made on a landline

More and more people are using cellphones, because of the convenience of having your phone with you at all times. From an economical standpoint, it doesn't make sense to pay for both a cell phone and a landline (especially if your budget is thin). So many people have decided to drop having a landline all together. The less people using a landline produces a negative downward trend, which is why we have negative linear correlation.

Answer:

((-1, 2), (1, 3), (1, 5), (-3, 4))

Step-by-step explanation:

For a set of ordered pairs to be considered a function, a domain value should have exactly just 1 range value.

If a domain value is having more than 1 range value assigned to it, it is not a function. In order words, an x variable value should have exactly just one y variable value assigned to it.

x variables are domain values while y variables are the range values.

In the ordered pairs, ((-1, 2), (1, 3), (1, 5), (-3, 4)), the two pairs, (1, 3), (1, 5), have the same x variable value with different y-variable values assigned to each. This renders the set of ordered pairs not to be a function. Domain value 1, is having different range value of 3 and 5.

B

Step-by-step explanation:

∠ c  = 90° ( angle in a semicircle ), thus

d = 180° - (16 + 90)° = 180° - 106° = 74° ( angles in a Δ )

If one angle is 16° then the measure of angle d is 76°.

An angle is the figure formed by two rays called the sides of the angle, sharing a common point called the vertex of the angle.

We know that each angle of a rectangle and square is equal to 90°. When we observe the given figure then we can see that angles are formed in a rectangle and a,b,c,d,14 and 16 all are in rectangle, so in this way, 14°+d=90°.

d=90-14

d=76°

Hence if one angle is 16° then the measure of angle d is 76°.

m is the slope of the line

b is the y-intercept of the line

The slope of a line is the measure of its steepness.

Given the equation y = 2x + 4, the slope of the line is 2 and the y-intercept is 4. The y-intercept shows that the line will cut the y-axis at y = 4

Answer:

Step-by-step explanation:

● 4x = 32 - x^2

Add x^2 to both sides

● 4x +x^2 = 32 -x^2+x^2

● x^2 +4x = 32

Substract 32 from both sides

● x^2+4x -32 =32-32

● x^2 +4x-32=0

That is a quadratic equation

We will use the determinant method

The determinant is b^2-4ac

● a = 1

● b = 4

● c = 32

● b^2-4ac = 4^2 -4×1×(-32) = 144

144 is positive so the parabola will cross the x-axis two times

● x = (-b -/+ √(b^2-4ac))/2a

● x = (-4 +/- 12) /2

● x = 8/2 or x= -16/2

● x = 4 or x =-8

The solutions are 4 and -8
