Answer:

C) The axis of symmetry is x = −1.5 and the vertex is (−1.5, 8.25).

Step-by-step explanation:

The axis of symmetry is x = − b/2a

= -(-3) / 2(-1)

= 3/(-2)

= -1.5

the vertex => x = -1.5

y= -(-1.5)²-3(-1.5)+6 =

-2.25 +4.5+6= 8.25

Gail is making costumes for a school play. Each rabbit costume needs one and one half yards of white fur fabric, a yard of blue

olga nikolaevna [1]

Answer:

Gail will need 12 yards of white fur, 8 yards of blue striped and 2 yards of the pink felt.

Step-by-step explanation:

We are given that,

The amount of yards for making one costume of different fabrics are,

White fur fabric = $1\frac{1}{2}$ = $\frac{3}{2}$ yards

Blue striped fabric = 1 yard

Pink felt for ears = $\frac{1}{4}$ yards.

So, we have,

The amount required to make 8 costumes are,

White fur fabric = $\frac{3}{2}\times 8$ = 3×4 = 12 yards

Blue striped fabric = 1×8 = 8 yards

Pink felt for ears = $\frac{1}{4}\times 8$ = 2 yards.

Thus, Gail will need 12 yards of white fur, 8 yards of blue striped and 2 yards of the pink felt.

Go step by step to reduce the radical. V108 VOVO try You must answer all questions above in order to submit.

katen-ka-za [31]

To reduce the radical, you have to factorize 108.

108 is a multiple of 3, so to factorize it, you can divide it by 3

$\frac{108}{3}=36$

You can rewrite the square root as:

$\sqrt[]{3\cdot36}=\sqrt[]{3}\cdot\sqrt[]{36}$

The square root of 36 is equal to 6 so you can write the expression as:

$\sqrt[]{3}\cdot\sqrt[]{36}=6\sqrt[]{3}$

Given m/n, find the value of x.

pickupchik [31]

Answer:

x = 152 degrees.

Step-by-step explanation:

The way the 2 angles are positioned indicates that they are corresponding angles.

Corresponding angles are equal.

x = 152 degrees.

Make you know what corresponding angles are and when they can be used. Make sure you also know what parallel lines are (2 or more lines whose distance is a constant). Make sure you also know what a transversal is (a line that crosses the parallel lines).
