To the nearest tenth, what is the distance between the point (10, -11) and (-1, -5)

Final answer:

To find the number of defective computer chips the company would expect out of the 36,000 chips they make each year, we can set up a proportion: 22 defective chips / 600 chips = x defective chips / 36,000 chips. Dividing both sides by 600, we find that x = 1,320. Therefore, we would expect approximately 1,320 of the 36,000 computer chips the company makes each year to be defective.

Explanation:

To find the number of defective computer chips the company would expect out of the 36,000 chips they make each year, we can set up a proportion:

22 defective chips / 600 chips = x defective chips / 36,000 chips

Cross-multiplying, we get 600x = 22 * 36,000

Dividing both sides by 600, we find that x = 22 * 36,000 / 600 = 1,320

Therefore, we would expect approximately 1,320 of the 36,000 computer chips the company makes each year to be defective.

Step-by-step explanation:

Answer:

a = 1 and b = 2

Step-by-step explanation:

Using the Quotient Rule>

d/dx[(sin x)/(2+cos x) ]

=   [(2 + cos x) * cosx -  sin x * - sin x)]  /  (2 + cos x)^2

= 2cos x + cos^2x + sin ^2 x) /  (2 + cos x)^2

But cos^2x + sin^2x = 1 so we have:

(1 +  2 cos x)  /   (2 + cos x)^2

- so a = 1 and b = 2.

Answer:

y<x+1      y>x-2

Step-by-step explanation:

upper line: (0,1) (-1,0)

y=x+1

Lower line: (0,-2) (2,0)

y=x-2

I did not see any solid boundry on the line

Shaded: y<x+1      y>x-2

Answer:

[tex]y <x+1[/tex]

[tex]y>x-2[/tex]

Step-by-step explanation:

According to the graph, the system is formed by two inequalities. Let's find out the equation to each line in first place.

Notice that the upper line passes through points (-1,0) and (0,1). First, we find its slope

[tex]m=\frac{y_{2}-y_{1} }{x_{2}-x_{1} }=\frac{1-0}{0-(-1)}=\frac{1}{1}=1[/tex]

Then, we use the point-slope formula to find the equation

[tex]y-y_{1} =m(x-x_{1} )\\y-0=1(x-(-1)\\y=x+1[/tex]

Now, the dashed line indiactes that the inequalities must have sings < or >.

Notice that point (0,0) is part of its solution, that means the inequality is

[tex]y <x+1[/tex]

We do the same process to find the other inequality.

The line passes through points (0,-2) and (2,0).

[tex]m=\frac{y_{2}-y_{1} }{x_{2}-x_{1} }=\frac{0-(-2)}{2-0}=\frac{2}{2}=1[/tex]

Then,

[tex]y-y_{1} =m(x-x_{1} )\\y-0=1(x-2)\\y=x-2[/tex]

Notice that point (0,0) is part of its solution, so the inequality is

[tex]y>x-2[/tex]

Therefore, the system of inequalities is

[tex]y <x+1[/tex]

[tex]y>x-2[/tex]

10 small boxes and 11 large boxes were shipped.

Step-by-step explanation:

Given,

Total boxes shipped = 21

Total volume of shipped boxes = 342 cubic feet

Volume of each small box = 10 cubic feet

Volume of each large box = 22 cubic feet

Let,

Number of small boxes = x

Number of large boxes = y

According to given statement;

x+y=21     Eqn 1

10x+22y=342    Eqn 2

Multiplying Eqn 1 by 10

[tex]10(x+y=21)\\10x+10y=210\ \ \ Eqn\ 3[/tex]

Subtracting Eqn 3 from Eqn 2

[tex](10x+22y)-(10x+10y)=342-210\\10x+22y-10x-10y=132\\12y=132[/tex]

Dividing both sides by 12

[tex]\frac{12y}{12}=\frac{132}{12}\\y=11[/tex]

Putting y=11 in Eqn 1

[tex]x+11=21\\x=21-11\\x=10[/tex]

10 small boxes and 11 large boxes were shipped.

Answer: [tex]6y^2i\sqrt{6}[/tex]

Step-by-step explanation:

For this exercise it is important to remember the following property:

[tex]\sqrt[n]{a^n}=a^{({\frac{n}{n})}}=a[/tex]

Then, given the expression:

[tex]\sqrt{-216y^4}[/tex]

You can follow these steps in order to simplify it:

1. Descompose 216 into its prime factors:

[tex]216=2*2*2*3*3*3[/tex]

2. The Product of powers property states that:

[tex](a^m)(a^n)=a^{(m+n)}[/tex]

Then:

 [tex]216=2^2*2*3^2*3[/tex]

3. Now you can substitute:

[tex]=\sqrt{-2^2*2*3^2*3*y^4}[/tex]

4. Finally, substituting [tex]\sqrt{-1}=i[/tex] and simplifying, you get:

[tex]=2*3*y^2i\sqrt{2*3}=6y^2i\sqrt{6}[/tex]

Answer:

Area [tex]=62.5\sqrt{6}[/tex] square units

[tex]AB=5\sqrt{15}[/tex] units

[tex]BC=5\sqrt{10}[/tex] units

Step-by-step explanation:

In a right triangle the altitude drawn to the hypotenuse is the geometric mean of the segments at which this altitude divides the hypotenuse.

So,

[tex]BD^2=15\cdot 10\\ \\BD^2=150\\ \\BD=\sqrt{150}=5\sqrt{6}\ units[/tex]

a. The area of the triangle ABC is

[tex]A_{ABC}=\dfrac{1}{2}\cdot BD\cdot AC=\dfrac{1}{2}\cdot 5\sqrt{6}\cdot (15+10)=\dfrac{125\sqrt{6}}{2}=62.5\sqrt{6}\ un^2.[/tex]

b. The legs of the right triangle are geometric means of the segment adjacent to this leg and the hypotenuse, so

[tex]AB^2=AD\cdot AC=15\cdot 25\Rightarrow AB=5\sqrt{15}\ units\\ \\BC^2=CD\cdot AC=10\cdot 25\Rightarrow BC=5\sqrt{10}\ units[/tex]

Hey there!

To find the slope of the two points that you were given, use the slope formula:

[tex]\frac{y2-y1}{x2-x1}[/tex]

y2 is the y value of the second point pair, y1 is the y value of the first point pair, x2 is the x value of the second point pair, and x1 is the x value of the first point pair.

Now, plug in your values:

y2= 9

y1= 6

x2= 6

x1= 3

[tex]\frac{9-6}{6-3}[/tex] = [tex]\frac{3}{3}[/tex] = 1

Therefore, the slope of the two points is 1.

Answer:

At 9pm Greta and Marge have collected the same amount  of money.

Step-by-step explanation:

Consider the provided information.

Let x represents the number of hours Greta and Marge are both collecting.

It is given that  Greta had already collected $45.00 till 11 am.

Greta = 45 + 15x

Marge collects money at a rate of $20 per hour.

Marge = 20x

Greta and Marge have collected the same amount  of money.

Thus,​

45 + 15x = 20x

45 = 5x

9 = x

Hence, once Marge starts collecting, it would take 9 hours to collect same amount of money.

9 hours after 11am is 8pm. It is given that there is a break time of 1 hour

Hence, at 9pm Greta and Marge have collected the same amount  of money.

The cost of one peppermint cookie is $0.60 and cost of one cinnamon sugar cookie is $0.30

Step-by-step explanation:

Let,

Cost of 1 peppermint cookie = x

Cost of 1 cinnamon cookie = y

According to given statement;

120x+30y=81     Eqn 1

70x+60y=60     Eqn 2

Multiplying Eqn 1 by 2

[tex]2(120x+30y=81)\\240x+60y=162\ \ \ Eqn\ 3[/tex]

Subtracting Eqn 2 from Eqn 3

[tex](240x+60y)-(70x+60y)=162-60\\240x+60y-70x-60y=102\\170x=102\\[/tex]

Dividing both sides by 170

[tex]\frac{170x}{170}=\frac{102}{170}\\x=0.60[/tex]

Putting x=0.60 in Eqn 2

[tex]70(0.60)+60y=60\\42+60y=60\\60y=60-42\\60y=18[/tex]

Dividing both sides by 60

[tex]\frac{60y}{60}=\frac{18}{60}\\y=0.30[/tex]

The cost of one peppermint cookie is $0.60 and cost of one cinnamon sugar cookie is $0.30

Answer:

[tex]d < 20\ donuts[/tex]

The graph of the solution set in the attached figure

Step-by-step explanation:

 Let

d ----> the possible number of donuts Monica brought

we know that

The number of donuts d multiplied by $0.50 plus the cost of a box of coffee for $5 must be less than $15

so

The inequality that represent this situation is

[tex]0.50d+5 < 15[/tex]

Solve for d

subtract 5 both sides

[tex]0.50d < 15-5[/tex]

[tex]0.50d < 10[/tex]            

Divide by 0.50 both sides

[tex]d < 10/0.50[/tex]      

[tex]d < 20\ donuts[/tex]

The solution is all whole numbers greater than zero and less than 20 ( I say greater than zero because the problem states that Monica brought some donuts)

The solution set is the interval {1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19}

The measure of m∠J=90°, m∠G=55° and m∠H=35°

Step-by-step explanation:

Inscribed angles subtended by a diameter are right angles. Hence angle GJH =90°

The diameter GH and chord GJ intercepts an arc with a measure of 70°.The measure of an arc of a circle is equal to the measure of the central angle that intercepts the arc. Hence angle GOJ=70°. Radius of circle GO=OJ, which means triangle GOJ is an isosceles triangle thus ∠OJG=∠OGJ =(180° -70°) /2 = 55°. m∠G=55°

m∠H = (180°-(90°+55°) ) = 180° - 145° =35°

Answer:

The correct answer is C. 5⁶

Step-by-step explanation:

1. Let's review the information given to us to answer the question correctly:

Number of hens in a bird enclosure = (5³)² * 5⁰

2. What is the total number of hens in the enclosure?

Let's recall a couple of properties of the exponents:

1. When you raise any number to a zero power you'll always get 1, with the exception of zero itself.

x⁰ = 1, x ≠ 0

2. The power of a power property says that to calculate a power of a power you just have to multiply the exponents, this way:

(x⁴)⁵ = x ⁴°⁵ = x²⁰

Now, applying those two properties, we have:

(5³)² * 5⁰ = 5³°² * 1 = 5⁶

The correct answer is C. 5⁶

Answer:

three angles measuring 109º, 25º, and 145º cannot create a triangle

three angles measuring 40º, 70º, and 65º cannot create a triangle

Step-by-step explanation:

Verify each dimensions

Part 1) three angles measuring 109º, 25º, and 145º

Remember that the sum of the interior angles of a triangle must be equal to 180 degrees

In this problem we have

[tex]109^o+25^o+145^o=279^o[/tex]

[tex]279^o> 180^o[/tex]

therefore

three angles measuring 109º, 25º, and 145º cannot create a triangle

Part 2) three sides measuring 9 m, 15 m, and 9 m

we know that

The Triangle Inequality Theorem states that the sum of any 2 sides of a triangle must be greater than the measure of the third side

Applying the triangle inequality theorem

1) 9+15 > 9 ---> is ok

2) 9+9 > 15 ---> is ok

therefore

three sides measuring 9 m, 15 m, and 9 m can create a triangle

Part 3) three angles measuring 40º, 70º, and 65º

Remember that the sum of the interior angles of a triangle must be equal to 180 degrees

In this problem we have

[tex]40^o+70^o+65^o=175^o[/tex]

[tex]175^o< 180^o[/tex]

therefore

three angles measuring 40º, 70º, and 65º cannot create a triangle

Part 4) three sides measuring 6 cm, 8 cm, and 10 cm

we know that

The Triangle Inequality Theorem states that the sum of any 2 sides of a triangle must be greater than the measure of the third side

Applying the triangle inequality theorem

1) 6+8 > 10 ---> is ok

2) 8+10 > 6 ---> is ok

3) 6+10 > 8 ---> is ok

therefore

three sides measuring 6 cm, 8 cm, and 10 cm can create a triangle
