DochEvi [55]3 years ago
6 0

Answer:

y = 2(x + 3)(x + 1)

Step-by-step explanation:

Use the formula y = a(x-b)(x-c)

b and c are the x-intercepts

The x-intercepts in this function are -3 and -1

y = a(x+3)(x+1)

substitute the point (-2, -1)

-2 = a(-2 + 3)(-2 + 1)

-2 = a(1)(-1)

-2 = -a

a = 2

y = 2(x + 3)(x + 1)

lapo4ka [179]
Rate of fill-up = 1/44 = 1/44 * 77/77 = 77/3388

Rate of emptying = 1/77 = 1/77 * 44/44 =44/3388

Combined Rate of Fill-up = 77/3388 - 44/3388 = 33/3388 = 3/308

Time for combined fill-up = 308/3 = 102.6667 hours = 102 hours and 40 minutes

Please help!!! Intersection of chords use formula a•b=c•d
scoray [572]

Given:

Length of chords of one segment = 11 and 8

Length of chords of other segment = 2 and x

To find:

The value of x.

Solution:

<em>If two chords intersect each other inside a circle, the products of length their segments are equal.</em>

\Rightarrow a \cdot b =c \cdot d

\Rightarrow 11 \cdot 8 =2 \cdot x

\Rightarrow 88 =2x

Divide by 2 on both sides.

$\Rightarrow\frac{88}{2} =\frac{2x}{2}

$\Rightarrow 44 =x

Switch the sides.

$\Rightarrow x=44

The value of x is 44.
