verify
your prediction.)

a. w-shaped; y-intercept (0,6); symmetrical with respect to the y-axis
b. o-shaped; y-intercept (0,6); symmetrical with respect to the y-axis
U-shaped; y-intercept (6, 0); assymmetrical with respect to the y-axis
n-shaped; y-intercept (0,6); assymmetrical with respect to the y-axi

Answer:

u-shaped; y-intercept (0,6); symmetrical with respect to the y-axis

Step-by-step explanation:

Given that y = 2x² + 6

The graph would be the shape of that of a parabola. It can be u shaped or n shaped depending on the value of the coefficient of a comparing with the standard equation y = ax² + bx + c. If a > 0, it is u shape and if a < 0, it is n shape.

For this question, since a > 0 it would be u shaped and the intercept can be gotten by putting x = 0.

Therefore y = 0² + 6 = 0

The intercept is at (0,6) and is symmetrical with respect to the y-axis

Annabelle is designing a garden. She will plant 3/12 of the lot with daffodils, 1/6 with roses, and 3/12 with tulips. How much o
zimovet [89]

Answer:

7/12 is left to plant sunflowers

Step-by-step explanation:

Let's add

1/6+ 3/12

Our denominators don't match, so we can't add yet.

Since 6 is evenly divided by 12, we can multiply just one term to get a common denominator.

Multiply 1 by 2, and get 2, then we multiply 6 by 2 and get 12.

Add to get the amount of garden used.

2/6+3/12= 5/12

Now subtract 12/12(the whole garden) from 5/12 to get remainder of garden

Answer is: 7/12

Reika [66]

Answer:

t_{4}=20

Step-by-step explanation:

Given:

The n^{th} term of the sequence is given as:

t_{n}=n^{2}+n

In order to find the fourth term of this sequence, we need to plug in 4 for n in the above expression and solve. This gives,

t_{4}=4^{2}+4\\t_{4}=16+4=20

Therefore, the fourth term of the sequence is t_{4}=20.
