Answer: 3,230

Explanation: when multiplying a decimal by a power of 10, simply count the number of zeroes in the power of 10, then move the decimal point that many places to the right to find the answer. Notice that 1,000 has three zeroes and when we multiply 3.23 by 1,000, our decimal point moves three places to the right giving us 3,230.

Find an equation of the circle that has center (-6, 6) and passes through (3,-4)

daser333 [38]

Answer:

(x+6)² + (y-6)² = 181

Step-by-step explanation:

equation of the circle in general is (x - a)² + (y - b)² = r²

center is (a, b) in our task a=-6 b=6

so equation of the circle is (x+6)² + (y-6)² = r²

we have point (3,-4) ⇒ x=3 y=-4

put x y in equation of the circle ⇒ (3+6)² + (-4-6)² = r² ⇒r² =181

⇒The equation of a circle is (x+6)² + (y-6)² = 181

What is 21⁄4 plus 4 3⁄10? A. 611⁄20 B. 613⁄20 C. 61⁄4 D. 61⁄2

Olegator [25]

Convert 1/4 and 3/10 to have a common denominator:

1/4 = 5/20

3/10 = 620

Now you have 2 5/20 + 4 6/20 = 6 11/20

The answer is A.

Apyramid was built about 2570 BC. Its original height was 453 feet, 11 inches, but

sweet [91]

Answer:

422.44 feet

Step-by-step explanation:

Let A, B, X, and H represent the left-most observation point, the observation point to its right, the point immediately below the apex, and the height of the apex, respectively.

Then the definition of the cotangent function tells us ...

AX = H·cot(42°)

BX = H·cot(48.85°)

Since the figure tells us AB = 100 feet, we have ...

AB = AX -BX

100 = H·cot(42°) -H·cot(48.85°)

H = 100/(cot(42°) - cot(48.85°)) ≈ 422.44 . . . . ft

The current height of the pyramid is 422.44 feet.
