Answer: clockwise 90 degrees

Step-by-step explanation:

Answer:

Clockwise 90º

Step-by-step explanation:

270º/90 = 3

This means to rotate the quadrilateral 3 times amongst the x and y axis.

Counterclockwise 90º x1 = y at (0,-3)

Cc90º x2 or cc180º = y at (3,0)

Cc90º x3 or cc270º = y at (0,3)

If you wanted to move clockwise to (0,3), you'd only have to move 90º

Counterclockwise 270º = Clockwise 90º

Answer:

  C and D

Step-by-step explanation:

Extraneous solutions arise in a couple of cases, both of which are illustrated in this list of answer choices.

1. Square roots (and other even-index radicals). The square root is defined only for positive arguments. When the radical is removed by squaring the equation, the possibility of negative arguments is introduced. Hence, there may be extraneous solutions.

Example:

  x = √(x +2)   ⇒  x² = x+2 . . . has 2 roots, one of which is extraneous

__

2. Rational function equations. Such an equation is only defined when the denominator is not zero. A method often taught for solution of these equations is "cross-multiplying"--essentially multiplying by the product of the denominators. In the case where this product is not the least common denominator, the equation will have an extra factor that can introduce an extraneous root.

__

The answer choices C and D are likely to have extraneous roots based on the above observations.

_____

Additional comment

Choice D would usually be solved by cross-multiplying. That would give the quadratic equation (x -3)² = 0, which only has solutions x=3. The denominators are zero at x=3, so these solutions are extraneous. If the right side is subtracted from the left side, the fractions can be combined to give ...

  ((x+3) -6)/((x -3)(x +3)) = 0   ⇒   1/(x+3) = 0 . . . . no solution

Step-by-step explanation:

Answer:

0.0051 = 0.51% probability that the thickness is less than 3.0 mm

Step-by-step explanation:

Normal Probability Distribution:

Problems of normal distributions can be solved using the z-score formula.

In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score of a measure X is given by:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the p-value, we get the probability that the value of the measure is greater than X.

Mean of 4.8 millimeters (mm) and a standard deviation of 0.7 mm.

This means that [tex]\mu = 4.8, \sigma = 0.7[/tex]

(a) Probability that the the thickness is less than 3.0 mm

pvalue of Z when X = 3. So

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]Z = \frac{3 - 4.8}{0.7}[/tex]

[tex]Z = -2.57[/tex]

[tex]Z = -2.57[/tex] has a pvalue of 0.0051

0.0051 = 0.51% probability that the thickness is less than 3.0 mm

Answer:

29 day) $15.00

30 day $15.00

31 day $15.00

The cost was the same for all three days

Step-by-step explanation:

Rover = 3/4 can

Bobo = 1/2 can

29(3/4) + 29(1/2) = 21.75 + 14.5 = 36.25 cans

36.25/3 = 12.08

must buy 4 packs of 3 at $5.00 each = $15.00

30(3/4) + 30(1/2) = 22.5 + 15 = 37.5 cans

37.5/3 = 12.5

must buy 4 packs of 3 at $5.00 each = $15.00

31(3/4) + 31(1/2) = 23.25 + 15.5 = 38.75 cans

38.75/3 = 12.92

must buy 4 packs of 3 at $5.00 each = $15.00

Answer:

Area of sector bounded by angle = 100.37 ft² (Approx.)

Step-by-step explanation:

Given:

Radius of a circle = 12 feet

Arc angle θ = 80°

Find:

Area of sector bounded by angle

Computation:

Area of sector bounded by angle = [θ/360][πr²]

Area of sector bounded by angle = [80/360][(3.14)(12)²]

Area of sector bounded by angle =[0.22][(3.14)(144)]

Area of sector bounded by angle = [0.22][452.16]

Area of sector bounded by angle = 100.37 ft² (Approx.)

Triangle LMN has vertices at L(-1,5),M(-1,0),N(-2,5), then the vertices are L'(-5, -1), M'(0, -1), N'(-5, -2).

To rotate a point counterclockwise:

For a point (x, y):

x' = x*cos(theta) - y*sin(theta)

y' = x*sin(theta) + y*cos(theta)

In this situation, rotate the triangle 90° counterclockwise about the origin.

The transformation equations to each vertex of the triangle states that:

For vertex L(-1, 5):

x' = -1*cos(90°) - 5*sin(90°) = -1*0 - 5*1 = -5

y' = -1*sin(90°) + 5*cos(90°) = -1*1 + 5*0 = -1

Therefore, vertex L' is (-5, -1).

For vertex M(-1, 0):

x' = -1*cos(90°) - 0*sin(90°) = -1*0 - 0*1 = 0

y' = -1*sin(90°) + 0*cos(90°) = -1*1 + 0*0 = -1

Therefore, vertex M' is (0, -1).

For vertex N(-2, 5):

x' = -2*cos(90°) - 5*sin(90°) = -2*0 - 5*1 = -5

y' = -2*sin(90°) + 5*cos(90°) = -2*1 + 5*0 = -2

Therefore, vertex N' is (-5, -2).

Thus, the vertices of the image triangle L'M'N' after rotating the original triangle 90° counterclockwise about the origin are: L'(-5, -1), M'(0, -1), N'(-5, -2).

Answer:

1. a. 75.39 in² b. 65.97 in²

2. Decreased

Step-by-step explanation:

1.

a. Find the surface area of the cheese before it is cut, round to the nearest hundredth.

Since the cheese is a cylinder with radius, r = 3 inches and height, h = 1 inch, its tital surface area, A = 2πr(r + h)

Substituting the values of the variables into the equation, we have

A = 2πr(r + h)

A = 2π(3 in)(3 in + 1 in)

A = (6π in)(4 in)

A = 24π in²

A = 75.39 in²

b. Find the surface area of the remaining cheese after the wedge is removed, round to the nearest hundredth.

Since the area of the wedge, A' is one-eight the area of the cheese, A

A'= A/8

= 75.39 in²/8

= 9.42 in²

The area of the remaining cheese is thus, area of cheese - area of wedge  = A - A' = 75.39 in² - 9.42 in² = 65.97 in²

Question 2 - Did the surface area increase, decrease, or remain the same

Since the area of the remaining cheese, A' = 65.97 in² < A = 75.39 in², area of original cheese, the surface area decreased.

Answer:

7

Step-by-step explanation:

The sum of the measures of the angles inside a triangle is 180°. Therefore, we can create the equation (6x+5)+60+73=180.

Then we simplify:

1. combine like terms. (6x+5)+60+73=6x+5+60+73=6x+138

2. 6x+138=180, -138 to both sides of the equation. the equation becomes 6x=42.

3. /6 to both sides of the equation. we can reach the conclusion that x=7

Answer:

Ship : 600 copies from Novato and 400 copies from Lodi to fulfill order at least cost ( $4600 )

Step-by-step explanation:

Order size :

600 Copies of texts from San Francisco and

400 Copies of texts from Sacramento.

Available notes in the company

700 copies of texts in Novato

800 copies of texts  in Lodi

Cost of sending copies of texts

Novato to San Francisco = $5

Novato to Sacramento = $10

Lodi to San Francisco = $15

Lodi to Sacramento = $4

considering Novato

700 copies are available hence the the least cost will be

600 * $5 ( to Francisco ) = $3000

considering Lodi

800 copies are available hence the least cost will be

400 * $4 ( to Sacramento ) = $1600

Therefore the least cost = $3000 + $1600 = $4600

Answer:

Long = 5√3

Step-by-step explanation:

Hypotenuse = 10

Short = 5

Long = ?

Apply Pythagorean theorem to find Long:

Long² = hyp² - short²

Long² = 10² - 5²

Long² = 100 - 25

Long² = 75

[tex]25\sqrt{3}=43.3\ \mathrm{units}[/tex]

Step-by-step explanation:

Area of a triangle = [tex]\frac{1}{2}ab\textrm{sin}(\theta)[/tex] where [tex]a[/tex] and [tex]b[/tex] are the sides of the triangle and [tex]\theta[/tex] is the angle between those two sides.

The side length are 10, and since its an equilateral triangle, the angle is 60 degrees. Thus, the area becomes [tex]\frac{1}{2}(10)(10)\textrm{sin}(60)=25\sqrt{3}=43.3\ \mathrm{units}[/tex]
