Answer:3.5

Step-by-step explanation:

1. To find the volume of the zone 1 cone, you need to subtract the smaller cone from the larger cone. The larger cone can be visualized as an entire cone, and the smaller cone as a cone that has been cut off from the top.

2. Given the radii and heights of the cones are, r1 = 4, r2 = 2, h = 12To find the volume of the zone 1 cone, Volume of cone = 1/3πr1²h1/3 × 3.14 × 4² × 6= 100.48 cubic units We now need to find the volume of the smaller cone and then subtract it from the volume of the larger cone. The height of the smaller cone is 6 units and its radius is 2 units. So, the volume of the smaller cone = 1/3 π (2)² (6)1/3 × 3.14 × 4 × 2= 16.74 cubic units Now, the volume of zone 1 cone can be found by subtracting the volume of the smaller cone from the volume of the larger cone.= 100.48 – 16.74= 83.74 cubic units

3. To find the volume of the zone 2 cone, we just need to use the formula of the volume of the cone. Volume of cone = 1/3πr²h

4. Given the radii and heights of the cones are, r1 = 4, r2 = 2, h = 12To find the volume of the zone 2 cone, we first find the volume of the entire cone. Volume of cone = 1/3πr²h1/3 × 3.14 × 4² × 12= 201.06 cubic units Now we find the volume of the smaller cone (zone 1).Volume of smaller cone = 1/3 πr²h1/3 × 3.14 × 2² × 6= 16.74 cubic units The volume of the zone 2 cone can be found by subtracting the volume of the smaller cone from the volume of the larger cone.= 201.06 – 16.74= 184.32 cubic units

5. To find the number of mosquitoes in zone 2 than in zone 1, we need to use the ratio of the volumes of zone 2 cone and zone 1 cone. Volume of cone = 1/3πr²hNumber of mosquitoes ∝ Volume of cone Since the height is the same for both cones, we can use the ratio of the radii to find the ratio of their volumes. Ratio of volumes = (Volume of zone 2 cone)/(Volume of zone 1 cone)= 184.32/83.74= 2.2So, there are 2.2 times more mosquitoes in zone 2 than there are in zone 1.

Answer: y=3x-1

Step-by-step explanation: If an equation is parallel to another equation, the slope (in this case, 3) is the same for both. So far we have, y=3x+b. To find the value of ”b” you substitute the given coordinate into the equation. So, 5=3(2)+b. When you solve, you get 5=6+b; subtract 6 from both sides to get -1=b. So, the equation of the line is y=3x-1.

FIND: ST

SOLUTION:

ST + TU = SU

x - 6 + 2x - 8 = 10

combine like terms:

3x - x = 10 + 8 + 6

x = 24/3

x = 8

plugin the value of x= 8 into the ST = x - 6

ST = x - 6

ST = 8 - 6

ST = 2

x - 6 + 2x - 8 = 10

8 - 6 + 2(8) - 8 = 10

The value of the equation x² - x + 3 is 37/9.

We have,

We can start by multiplying both sides of the equation by x:

2x - 3/x = x + 1

2x - 3 = x^2 + x

Rearranging and simplifying, we get:

x^2 - x + 3 = (2x - 3) + x^2

x^2 - x + 3 = x^2 + 2x - 3

-x + 3 = 2x - 3

5 = 3x

x = 5/3

Now we can substitute x into the equation x^2 - x + 3:

x^2 - x + 3 = (5/3)^2 - 5/3 + 3

x^2 - x + 3 = 25/9 - 15/9 + 27/9

x^2 - x + 3 = 37/9

Therefore,

The value of x² - x + 3 is 37/9.

The f′(a) when a = −6 is -7. This means that the slope of the tangent line of the graph of f(x) at x = -6 is -7.

To compute f′(a) algebraically for the given value of a, we use the following differentiation rule which is known as the Power Rule.

This states that:If f(x) = xn, where n is any real number, then f′(x) = nxⁿ⁻¹This is valid for any value of x.

Therefore, we can differentiate f(x) = −7x + 5 with respect to x using the power rule as follows:

f(x) = −7x + 5

⇒ f′(x) = d/dx (−7x + 5)

⇒ f′(x) = d/dx (−7x) + d/dx(5)

⇒ f′(x) = −7(d/dx(x)) + 0

⇒ f′(x) = −7⋅1 = −7

Hence, the derivative of f(x) with respect to x is -7.Now, we evaluate f′(a) when a = −6 as follows:f′(x) = −7 evaluated at x = −6⇒ f′(−6) = −7

Therefore, f′(a) when a = −6 is -7. This means that the slope of the tangent line of the graph of f(x) at x = -6 is -7.

The required answer is :

a. The third side of the reflective sticker cannot be 12 cm long.

b. It is not possible to form a triangle with side lengths of 6 cm, 8 cm, and 2 cm.

According to the triangle inequality theorem, the sum of any two sides of a triangle must be greater than the third side.

In this case, the sum of the two given sides (6 cm + 8 cm = 14 cm) is less than the length of the third side (12 cm).

Therefore, it is not possible to form a triangle with side lengths 6 cm, 8 cm, and 12 cm.

(b) The third side of the reflective sticker cannot be 2 cm long.

Applying the triangle inequality theorem, the sum of any two sides of a triangle must be greater than the third side.

The sum of the two given sides (6 cm + 8 cm = 14 cm) is greater than the length of the third side (2 cm).

Hence, it is not possible to form a triangle with side lengths 6 cm, 8 cm, and 2 cm.

Evaluate the exponent

Multiply the numbers

Add the numbers

Evaluate the square root

Multiply the numbers

Given the expression:

To factor the given expression, we need two numbers the product of them = 100 and the sum of them = 20

We will factor the number 100

100 = 1 x 100 ⇒ 1 + 100 = 101

100 = 2 x 50 ⇒ 2 + 50 = 52

100 = 4 x 25 ⇒ 4 + 25 = 29

100 = 5 x 20 ⇒ 5 + 20 = 25

100 = 10 x 10 ⇒ 10 + 10 = 20

So, the suitable numbers are 10, 10

so, the factorization will be as follows:

The given expression is a complete square.

1.

it is always the same.

the usual equation of a line is

y = ax + b

"a" being the slope, "b" being the y-intercept (the y-value when x = 0).

we see that the y-value is +3 when x = 0. that is "b".

for the slope we pick 2 points (with integer coordinates, if possible).

I see e.g. (0, 3) and (3, 0)

x changes by +3 (from 0 to 3).

y changes by -3 (from 3 to 0).

the slope "a" is -3/+3 = -1

the equation is

y = -x + 3

2.

and again the same

we see that the y-value is -3 when x = 0. that is "b".

I see e.g. (0, -3) and (3, 0) as points.

x changes by +3 (from 0 to 3).

y changes by +3 (from -3 to 0).

the slope "a" is +3/+3 = 1.

the equation is

y = x - 3

1) The line integral value is : ∫F dr = 6

2) The line integral value is : ∫F dr = 6

3) The line integral value is : ∫F dr = 6

Here we are given:

\(F.dr = (3x + 2y)dx + (2x -2z)dy + (3x -2y)dz,\)

where\(\vec{F}\) is a conservative field

So,

f(x, y , z) = \(\int\limits (3x + 2y)dx + (2x -2z)dy + (3x -2y)dz,\)

f(x , y , z) = (3zx +2yx) + (2xy - 2zy) + (3xz - 2yz) + c(x , y , z)

\(f(x, y, z) = (6xz + 4xy - 4yz) + c(x, y, z)\)

Now substitute the values of x , y ,z ,

1)

Line segment from (0, 0 , 0) to (1,1 ,1)

∫F dr = f(1,1,1) - f(0,0,0)

= |6 + 4 - 4 |- |0 + 0 - 0|

∫F dr = 6

2)

Line segment from (0,0,0) to (0,0,1) to (1,1,1)

First we take (0,0,0) to (0,0,1)

\(\int _c \vec{F}.\vec{dr}=f(0,0,1)-f(0,0,0) =[6(0)(1)+4(0)(0)-4(0)(1)]-[6(0)(0)+4(0)(0)-4(0)(0)] =[0+0-0]-[0+0-0]\)

∫F dr = 0

\(\Rightarrow \int _{c}\vec{F}.\vec{dr}=0+6 [F.dr = 6\)

3)

Line segment from (0,0,0) to (1,0,0) to (1,1,0) to (1,1,1)

First we take (0,0,0) to (1,0,0)

\(\int _c \vec{F}.\vec{dr}=f(1,0,0)-f(0,0,0) =[6(1)(0)+4(1)(0)-4(0)(0)]-[6(0)(0)+4(0)(0)-4(0)(0)] =[0+0-0]-[0+0-0]\int _{c}\vec{F}.\vec{dr}=0\)

Next we take (1,0,0) to (1,1,0)

\(\int _c \vec{F}.\vec{dr}=f(1,1,0)-f(1,0,0) = [6(1)(0) + 4(1)(1) − 4(1)(0)] - [6(1)(0) + 4(1)(0) — 4(0)(0)] = [0+4-0] - [0+0-0]\int _{c}\vec{F}.\vec{dr}=4\)

Lastly we take (1,1,0) to (1,1,1)

\(F.dr = f(1,1,1) ƒ(1,1,0) = [6(1)(1) +4(1)(1) − 4(1)(1)] - [6(1)(0) + 4(1)(1) — 4(1)(0)] =[6+4-4]-[0+4-0]\int _{c}\vec{F}.\vec{dr}=2\)

Adding the three results we get

\(\Rightarrow \int _{c}\vec{F}.\vec{dr}=0+4+2\\\\\int\limits F.dr = 6\)

Therefore we see that the Line integral for the three cases comes out to be same between the initial and final points since it is independent of the path taken.

The probability that exactly 3 jellies selected are yellow is 0.2149.

Given that the box contains 19 yellow, 31 green, and 32 red jelly beans. Therefore, the probability of getting a yellow jelly bean is,

Probability of Yellow jelly beans

= Number of Yellow jelly beans / Total number of jelly beans in the box

= 19 / (19 + 31 + 32)

= 19 / 82

= 0.2317

Now, as per the binomial probability distribution:

P(x) = ⁿCₓ (pˣ) (q⁽ⁿ⁻ˣ⁾)

Where,

x is the number of successes needed,

n is the number of trials or sample size,

p is the probability of a single success, and

q is the probability of a single failure.

Therefore, the probability of getting exactly 3 yellow jelly beans is:

P(x=3) = ⁹C₃ (0.2317³) (1-0.2317)⁽⁹⁻³⁾

           = 84 × 0.012438 × 0.205676

           = 0.2149

Hence, the probability is 0.2149.
