Annie is birdwatching
during her hike.
She records the types of birds she sees in
the table. What is the experimental
probability for each type of bird she sees
during her hike?

Step-by-step explanation:

I assume that "ground" is at 0 ft height. which is in an actual scenario not airways the case.

y = -16x² + 64x + 89

shows us that the tower is 89 ft tall (the result for x = 0, at the start).

anyway, if the original assumption is correct, then we need to solve

0 = -16x² + 64x + 89

the general solution for such a quadratic equation is

x = (-b ± sqrt(b² - 4ac))/)2a)

in our case

a = -16

b = 64

c = 89

x = (-64 ± sqrt(64² - 4×-16×89))/(2×-16) =

= (-64 ± sqrt(4096 + 5696))/-32 =

= (-64 ± sqrt(9792))/-32

x1 = (-64 + 98.95453501...)/-32 = -1.092329219... s

x2 = (-64 - 98.95453501...)/-32 = 5.092329219... s

the negative solution for time is but useful here (it would be the time calculated back to ground at the start).

so, x2 is our solution.

the rocket hits the ground after about 5.09 seconds.

Answer:

4th option

Step-by-step explanation:

the distributive property is

a(b + c) = ab + ac

that is each term in the parenthesis is multiplied by a

Answer:

a(b+c)=ab+ac

Step-by-step explanation:

The distributive property is when it distributes the outside variable with whatever is in the parenthesis.

For example, 2(1+3) is 2(1)+2(3)= 2+6=8.

Force (F) = WSin(angle)

F = 2000×Sin(10)

Therefore, F = 347lb.

Hi Student!

This question is fairly simple because it gives us an equation and they also give us a value for the variable that is within the equation and they tell us evaluate the expression.  So let's plug in the values and solve.

Plug in the values

Factor out the exponent

Therefore, the final answer that we would get when substituting m with 9 in the given equation is that we get 86.

Answer:

111 (base 8) = 64 +8+1 =73(base10)

111 (base 2) = 4+2+1 =7(base 10)

Sum =73+7=80 (base 10)

8| 80|

8 | 10 | 0

8 | 1 | 2

8| 0 | 1

= 120 (base8)

80 (base10) = 120 (base 8)

Step-by-step explanation:

mark as brilliant

The next whole number after 111 in the base-two system is 1000.

In the base-two system (binary), the numbers are represented using only 0 and 1. After 111 in the base-two system, the next whole number is 1000.

To convert 1000 from base-two to base-ten (decimal), we can calculate as follows:

1 * 2^3 + 0 * 2^2 + 0 * 2^1 + 0 * 2^0 = 8 + 0 + 0 + 0 = 8

So, the next whole number after 111 in the base-two system is 1000.

The surface area of the large sphere is 128π cm²

Two spheres have volumes of 8π cm3 and 64π cm3. If the surface area of the smaller sphere is 16π cm2, what is the surface area of the larger sphere?

The given parameters can be represented using the following ratio:

Small Area : Large Area = Small Volume : Large Volume

Substitute the given parameters

16π : Large Area = 8π : 64π

Express as fraction

Large/16π = 64π/8π

Multiply both sides by 16π

Large = 128π

Hence, the surface area of the large sphere is 128π cm²

Answer:

y = 9

Step-by-step explanation:

given that y varies inversely as x then the equation relating them is

y = [tex]\frac{k}{x}[/tex] ← k is the constant of variation

12 = [tex]\frac{k}{6}[/tex] ← multiply both sides by 6 to clear the fraction

72 = k

y = [tex]\frac{72}{x}[/tex] ← equation of variation

The break-even point (rounded to the nearest dollar) for Evergreen Corporation for the current year is: A. $1,724,138.

First step is to calculate the Variable costs

Variable costs = $500,000 + $250,000 + $275,000 + $750,000

Variable costs = $1,775,000

Second step is to calculate the Contribution margin ratio

Contribution margin ratio = (Sales - Variable costs) / Sales

Contribution margin ratio= ($3,500,000 - $1,775,000) / $3,500,000

Contribution margin ratio= 0.493×100

Contribution margin ratio =49.3%

Now let calculate the Break-even point

Break-even point = Fixed costs / Contribution margin ratio

Break-even point= ($600,000 + $250,000) / 0.493

Break-even point= $1,724,137.9

Break-even point =$1,724,138 (Approximately)

Therefore the break-even point (rounded to the nearest dollar) for Evergreen Corporation for the current year is:$1,724,138.
