Answer:

1274.7 cubic meters

Step-by-step explanation:

Because the equation to find volume of a cone is V = πr²(h/3), you would have to plug in your values which are h = 5.2m, and r = 15.3m. Once you do the math you will get 1274.72 cubic meters, or 1274.7 when rounded to the nearest tenth.

Answer:

146°

Step-by-step explanation:

Points A and B are the endpoints of an arc of a circle. Chords are drawn from the two endpoints to a third point, C, on the circle. Given m arch AB=64° and ⦣ABC=73°, m ⦣ABC=__ ° and m arch AC=__ °.

Solution:

Given that:

arc AB = 64° and ⦣ABC=73°

The Central Angle Theorem states that the central angle from two chosen points A and B on the circle is always twice the inscribed angle from those two points. The inscribed angle is any point along the outer arc AB and the two points A and B.

Therefore arc AC is the central angle of ⦣ABC. Using the central angle theorem gives:

arc AC = 2 * ⦣ABC

substituting:

arc AC = 2 * 73

arc AC = 146°

-2 = 14 + b

b = -16

Answer:

Step-by-step explanation:

The required mass of reactants can be computed from the number of moles of product.

  moles of ZnCl₂ = (1.5 g)/(136.282 g) ≈ 0.0110066 moles

Then the mass of Zn required is ...

  mass of Zn = (0.0110066 mol)(65.382 g/mol) = 0.71963 g

Two moles of HCl are used in the reaction with each mole of Zn, so the mass of HCl required is ...

  mass of HCl = 2(0.0110066 mol)(36.458 g/mol) = 0.80256 g

_____

Comment

The discrepancy in the last two decimal places of the weights above versus the calculator output below comes from rounding of moles of Zn to 4 significant digits, instead of 5 or more. The number of moles of ZnCl₂ is closer to 0.0110066.

Answer:

f(8) = 195

Step-by-step explanation:

When the x if f(x) is replaced with an 8, this just means that it is the eighth term. All you really have to do is replace every X in the function to find the answer.

f(8) = 3 + 3(8)²

f(8) = 3 + 3(64)

f(8) = 3 + 192

f(8) = 195

Cos=Adjacent/hypotenuse

Cos30=rad3/2

The cosine function for Ф = 30 is equivalent to :

cos(30) =√3/2.

There are six major trigonometric functions as -

We can write the relation between them as -

Also the following trigonometry relations hold true -

sin²Ф + cos²Ф = 1

1 + tan²Ф = sec²Ф

1 + cot²Ф = cosec²Ф

Given is a right angled triangle as shown in the image having 60 - 90 - 30 orientation and the measured sides as shown in the image.

We can write the cosine function as -

cosФ = Base/Hypotenuse

cos(30) = √3/2

So, we can conclude that the cosine function for Ф = 30 is equivalent to :

cos(30) =√3/2

Therefore, the cosine function for Ф = 30 is equivalent to :

cos(30) =√3/2.

hope this helped <3

Answer:

D.0

Step-by-step explanation:

If you graph the equation you can see that it doesn't cross the x-axis. It doesn't go lower than y=1. If you don't have a graphing calculator use Desmos. Also the +1 at the end of the equation tells you that it won't go lower than y=1.

Answer:

Never your answer is 0

Step-by-step explanation:

The equation creates what's called a parabola the line curves up the 1 represents the y axis so the line curves up from the y axis point 1 never touching the x axis

Answer:

68 000

Step-by-step explanation:

When we round to the nearest thousand, we have to look which thousand is closer to the value. So in our case 67795 is 205 away from 68 000 and is 795 away from 67000. From this we know that 68 000 is closer, therefore if we round 67 795 to the nearest thousand we will get 68 000.
