in vertex form

y=a(x-h)^2+k

the vertex is (h,k) and the axis of symmetry is x=h


put into vertex form

y=ax^2+c

y=a(x)^2+c

y=a(x-0)^2+c

h=0, k=c

the vertex is (0,c)

the axis of symmetry is x=0

State the vertex and axis of symmetry of the graph of y=ax^2+c

General form of quadratic equation is y=ax^2 + bx +c

There is no bx in our given equation, so we put 0x

Given equation can be written as y=ax^2 + 0x +c

a=a , b=0

Now we use formula to find vertex

x=\frac{-b}{2a}

x=\frac{-0}{2a}=0

Now we plug in 0 for 'a' and find out y

y=a(0)^2 + 0x +c= c

So our vertex is (0,c)

The axis of symmetry at x coordinate of vertex

So x=0 is our axis of symmetry

Answer:  5 cos x

<u>Step-by-step explanation:</u>

y = sin x     is       y = cos x        shifted to the right π/2 units.

y = 5 sin (x + π/2)     is a shift to the left π/2 units (which results in cos x) and    .                                 an amplitude of 5.

--> y = 5 cos x

An $42 item was marked down by 50%<br><br> what is the new cost of the item?
Nataly_w [17]

Answer:

New Cost of item is \$ 21

Step-by-step explanation:

Given:

Original Cost of item = \$ 42

Item was marked down by 50\%

To Calculate Cost after 50\% marked  down we need to multiply original cost by 50 and then divide by hundred.

Cost after  marked down = \frac{42 \times 50}{100}= \$21

Now New cost of the item is calculated by Subtracting Cost after 50\% marked down by Original Cost of item.

New cost of the item =  \$ 42 - \$ 21 = \$21

Evaluate b-(-1/8)+c where b=2 and c=-7/4​
tatiyna

Answer:

3/8

Step-by-step explanation:

Evaluate b - -1/8 + c where b = 2 and c = -7/4:

b - (-1)/8 + c = 2 - (-1)/8 - 7/4

Put 2 + 1/8 - 7/4 over the common denominator 8. 2 + 1/8 - 7/4 = (8×2)/8 + 1/8 + (2 (-7))/8:

(8×2)/8 + 1/8 - (7×2)/8

8×2 = 16:

16/8 + 1/8 - (7×2)/8

2 (-7) = -14:

16/8 + 1/8 + (-14)/8

16/8 + 1/8 - 14/8 = (16 + 1 - 14)/8:

(16 + 1 - 14)/8

16 + 1 = 17:

(17 - 14)/8

| 1 | 7

- | 1 | 4

| 0 | 3:

Answer:  3/8
