Answer:
1.) 8 = 8
2.) -12 = -12
3.) -3y² = -3y²
4.) 6x² + 36x = 6x(x + 6)
5.) 7x - 14x² = 7x(1 - 2x)

Answer:</h3>
5.3
<h3>
Step-by-step explanation:</h3>
The mnemoic SOH CAH TOA reminds you that ...
... Tan = Opposite/Adjacent
... tan(24°) = x/12
Then multiplying by 12 gives ...
... 12·tan(24°) = x = 5.34274 ≈ 5.3
Answer:
y + 5 = 2(x - 3) (Answer A)
Step-by-step explanation:
Since the slope and a point on the curve are given, use the point-slope formula for the equation of a straight line:
y - k = m(x - h)
Here, m = 2, h = 3 and k = -5, so we have:
y + 5 = 2(x - 3) (Answer A)
Step-by-step explanation:
We know that the lenght of an arc is pi. Therefore:
pi = 1/2pi*r where r is the radius
r = 2
On one side we have 2 circles, so the lenght of 1 side is 2. The perimeter will be 2*4 = 8.
*Note: the first equation I wrote can be derived from the general equation for calculating the lenght of a circumference known its radius (L = 2 * pi * r).
