Answer:

16

Step-by-step explanation:

(-2i)(8i)

(2(cos(3π/2)+i×sin(3π/2)))×(8(cos(π/2)+i×sin(π/2)))

2×8(cos(3π/2+π/2)+i×sin(3π/2+π/2))

16(cos(2π)+i×sin(2π))

16(cos(0+2π)+i×sin(0+2π))

16(cos(0)+i×sin(0))

Answer: 138

Step-by-step explanation:

Number of 7th graders in music programs = 345

Percentage in choir = 35%

Percentage in orchestra = 25%

Percentage in band = 100% - (35% + 25%) = 100% - 60% = 40%

The number of 7th graders in music programs are in band will then be:

= Percentage in band × Total 7th graders

= 40% × 345

= 0.4 × 345

= 138 students

Answer: x=-1

Step-by-step explanation: Here is one way of answering this question. First you need to subtract 7 from both sides and that will leave you with -22=22x. Then you just divide 22 on both sides. So that will give you an answer of -1=x or x=-1

A slope is also known as the gradient of a line. The correct option is B.

A slope also known as the gradient of a line is a number that helps to know both the direction and the steepness of the line.

slope = (y₂-y₁)/(x₂-x₁)

Since for the two functions to be inverse of each other, the line of equations must bisect each other at 90° so that the product of the slope of the two equations is equal to -1.

For the second graph, the slope of the blue line is,

m₁ = (-1-0)/(0-4) = 0.25

The slope of the green line is,

m₂ = (-4-0)/[0-(-1)] = -4

Now, the product of the slope can be written as,

0.25×-4 = -1

Since the product is -1, the function is inverse of each other.

Hence, the correct option is B.

Answer:

h = V / πr²

Step-by-step explanation:

V = πr²h

Where,

V = volume of a cylinder

π = π

r = radius of the cylinder

h = height of the cylinder

V = πr²h

Solve for h

V = π × r² × h

Divide both sides by π × r²

h = V / π × r²

h = V / πr²

Height of the cylinder = volume of the cylinder / pie × r²

Answer:

x = 59

Step-by-step explanation:

All the angles in a triangle add up to 180

Add all the known angles

83 + 38 = 121

To find the third angle, subtract the total of all the angles by the total of the known angles

180 - 121 = 59

Answer:

0.3

Step-by-step explanation:

Given that:

Probability of growing into a healthy plant = probability of success (p) = 75% = 0.75

Number of seeds planted(n) = 9

Probability that exactly 2 don't grow is equivalent to having 7 that grows (9 - 2) = 7 = r

Using binomial distribution formula :

nCr * p^r * (1 - p)^(n-r)

9C7 * 0.75^7 * (1 - 0.75)^(9 - 7)

9C7 * 0.75^7 * 0.25^2

36 * 0.13348 * 0.0625

= 0.3003387

= 0.3

Hence, probability that exactly 2 don't grow is 0.3

Answer:

C. (Chanterelle mushrooms cost less by $0.90)

Step-by-step explanation:

Divide 11.25 by 2/3, for the total amount of pound for the Cremini.

Do the same thing for Chanterelle, but the numbers given for it.

We than find out that Cremini=16.87, and Chanterelle=15.98

Now that we know Cremini is more that Chanterelle, we need to find the difference, by subtracting The bigger number by the smaller number.

Our answer is 0.89, but we will round it to 0.90.

Now we know that the Cremini costs more by $0.90, and the Chanterelle costs less by $0.90

Answer:

Step-by-step explanation:

Cost of 1 lb of Cremini mushrooms= 11.25×3/2=33.75/2=16.875 $≈$16.88

Cost of 1 lb of Chanterelle mushrooms=7.99×2/1=$15.98

Chanterelle mushrooms cost 16.88-15.98=$0.90 less
