Mathematics
1 answer:
Vlada [557]3 years ago
5 0

Answer:

Step-by-step explanation:

Vertex of the given parabola = (1, -4)

Since, vertex form of a parabola is given by,

y = (x - h)² + k

Here (h, k) is the vertex

Now substitute the coordinates (1, -4) in the equation.

y = (x - 1)²- 4 [Vertex Form]

Further solve this equation,

y = x² - 2x + 1 - 4

y = x² - 2x - 3 [Standard form]

Further write this equation in the factored form,

y = x² - 3x + x - 3

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

y = (x + 1)(x - 3) [Factored form]

Multiply 3/7 by the reciprocal of -3/14​
Alexandra [31]

Multiplying 3/7 by the reciprocal of -3/14,

\frac{3}{7} \times  \frac{14}{ - 3} \\  =  \frac{1}{1} \times  \frac{2}{ - 1} \\  =  \frac{2}{ - 1} \\  =  - 2

Find the measure of d.
ad-work [718]

Answer:

d = 123

Step-by-step explanation:

The given figure above is an inscribed quadrilateral with all four vertices lying on the given circle, thereby forming chords each.

Therefore, the opposite angles of the above quadrilateral are supplementary.

This means:

c + 31 = 180 , and

d + 57 = 180

Find the measure of d:

d + 57 = 180

Subtract 57 from both sides.

d + 57 - 57 = 180 - 57

d = 123
