Answer:

12.56km

Step-by-step explanation:

circumference formula is C= 2(π)(r)

r= 2 so

C=2(π)(2)

C= 12.56

Answer:

For n=6, the given vectors will be collinear.

Step-by-step explanation:

Collinear vectors are the vectors which lie on the same line or parallel lines. In order to find if two vectors are collinear, their ratio is found. If the ratio is same for all unit vectors then the vectors are collinear.

Given

[tex]a = (a_1, a_2) = (3,2)\\b = (b_1, b_2) = (9,n)[/tex]

The ratio of first unit vectors is:

[tex]\frac{a_1}{b_1} = \frac{3}{9} = \frac{1}{3}[/tex]

In order for the vectors to be collinear the other ratio should also be 1/3

[tex]\frac{a_2}{b_2} = \frac{1}{3}[/tex]

Writing it mathematically

[tex]\frac{2}{n} = \frac{1}{3}\\2*3 = n\\n = 6[/tex]

Hence,

For n=6, the given vectors will be collinear.

Answer:

Sarah had 16 stickers. Al gave her 25 more. How many stickers does Sarah have now? 41

Step-by-step explanation:

Answer: 41

Step-by-step explanation: The key word in this sentence is more. She already has 16 and she is getting another 25. So that means you have to add 16 and 25 to find out how much she has now. The answer would be 41.

Answer:

Animals eat plants, and when they do, they obtain the carbon. Later, they release that carbon by means of respiration. Fungus, Bacteria, Algae and other microorganisms create carbon when they decompose dead plants and animals.

Step-by-step explanation:

Não porque a caixa seria muito menor que o cano.

Answer:

A)  x^2 + 2x+ y^2 - 4y + z^2 - 2z - 63 = 0

B) radius = 5

center  = (4,-1,-3)

Step-by-step explanation:

[tex]x^2 + y^2 + z^2 - 8x + 2y + 6z + 1 = 0[/tex]

A ) Determine the curve in which the sphere intersects the yz-plane

determine the radius ( r ) =  √((6-(-1))2+(-2-2)2+(3-1)2) = √69

next the equation of the sphere ( curve in which the sphere intersects the yz-plane )

x^2+2x+y^2-4y+z^2-2z-63 = 0

B) determine the center and radius of the sphere

X^2 + y^2 + z^2 -8x + 2y +6z + 1 = 0

(x-4)2+(y+1)2+(z+3)2 = 25 = 52

radius = 5

center  = (4,-1,-3)

divide $3.20 to get the cost per ounce, and multiply it by 6 to get the price for 6 ounces.

6 ounces = $1.92

Answer:

Probability cured of cervical cancer =  18C0 (0.30)⁰(0.70)¹⁸ +  18C1(0.30)(0.70)¹⁷

Step-by-step explanation:

Given:

Patients cured = 30% = 0.30

Number of patients (n) = 18

Probability cured of cervical cancer = P(X≤1)

Probability cured of cervical cancer  = P(X=0) + P(X=1)

Probability cured of cervical cancer =  18C0 (0.30)⁰(0.70)¹⁸ +  18C1(0.30)(0.70)¹⁷

Answer:

The last graph

Step-by-step explanation:

You have to solve for n that is where you get the plot then you have to remember in inequalities if you divide by a negative you have to switch the sign. The inequality is not a less than or equal to or greater than or equal to so the plot would be an open circle. Because we switched the sign it goes down the left side of the graph because of the direction the sign is pointing to.

Answer:

second graph

Step-by-step explanation:

when you solve for the value of n, you will obtain

n=-1

introducing the sign

which is n>-1

hence the above response

Answer:

The fourth vertex is D(8, 0)

Step-by-step explanation:

Let A(0, 0), B(2, 4), and C(10, 4) be the three vertices of a parallelogram ABCD and let its fourth vertex be D(a, b).

Join AC and BD. Let AC and BD intersect at point O.

So, O would be the midpoint of AC as well as that of BD.

[tex]A\left(0,\:0\right)=\left(x_1,\:x_2\:\right)[/tex]

[tex]C\left(10,\:4\right)=\left(x_2,\:x_2\:\right)[/tex]

The midpoint of AC is:

[tex]\mathrm{Midpoint\:of\:}\left(x_1,\:y_1\right),\:\left(x_2,\:y_2\right):\quad \left(\frac{x_2+x_1}{2},\:\:\frac{y_2+y_1}{2}\right)[/tex]

[tex]\left(x_1,\:y_1\right)=\left(0,\:0\right),\:\left(x_2,\:y_2\right)=\left(10,\:4\right)[/tex]

[tex]=\left(\frac{10+0}{2},\:\frac{4+0}{2}\right)[/tex]

[tex]=\left(5,\:2\right)[/tex]

The midpoint of BD is:

[tex]=\left(\frac{a+2}{2},\:\frac{b+4}{2}\right)[/tex]

so

∵  [tex]\frac{a+2}{2}=5[/tex]

[tex]a+2=10[/tex]

[tex]a=8[/tex]

∵ [tex]\frac{b+4}{2}=2[/tex]

[tex]b+4=4[/tex]

[tex]b=0[/tex]

Hence, the fourth vertex is D(8, 0)

Answer:

x is 3 y is 52        x is 50, y is 70

Step-by-step explanation:

1

we know y=14x=12x+6 since they are vertical angles, and correlating angles.

14x=12x+6

2x=6

x=3

subsitute x=3

y=14(x)   turns into y=52

x is 3 y is 52

2.

x+20=y  since alternate interior

y+2x+10=180    because they are supplementary

x+20+2x+10=180    subsitute  for y

3x+30=180

3x=150

x=50

50+20=y

70=y

Answer:

Therefore, the slope of the original line is 1/2. A line perpendicular to another has a slope that is the negative reciprocal of the slope of the other line. The negative reciprocal of the original line is –2, and is thus the slope of its perpendicular line.

Answer:

=10a+13b

Step-by-step explanation:

Let's simplify step-by-step.

3(2a+3b)+2(2a+2b)

Distribute:

=(3)(2a)+(3)(3b)+(2)(2a)+(2)(2b)

=6a+9b+4a+4b

Combine Like Terms:

=6a+9b+4a+4b

=(6a+4a)+(9b+4b)

=10a+13b

Answer:

c. -8

Step-by-step explanation:

Given:

[tex] \frac{4b \div c}{1 - a} [/tex]

a = 5, b = 8, and c = 1

To evaluate, plug in the values into the expression given.

Thus:

[tex] \frac{4(8) \div 1}{1 - 5} [/tex]

[tex] \frac{32 \div 1}{1 - 5} [/tex]

[tex] \frac{32}{-4} [/tex]

[tex] \frac{8}{-1} = - 8 [/tex]
