lapo4ka [179]2 years ago
3 0

Answer:

discriminant: 64

Step-by-step explanation:

The discriminant of a quadratic is the expression inside the radical of the quadratic formula.

b^ 2 − 4 ( a c )

Substitute in the values of  a ,  b , and  c .

( − 8 )^ 2− 4 ( 6 ⋅ 0 )

Simplify each term.

Raise  − 8  to the power of  2.

64  −  4  ( 6  ⋅  0 )

Multiply  6  by  0 .

64   −  4  ⋅  0

Multiply  − 4  by   0 .

64  +  0

Add  64  and  0 .

64

Ppppppppppllllllllls I need helppppppp​
Phantasy [73]

Answer:

ΔABC≅ΔDEC by AAS

Step-by-step explanation:

You can use the AAS method of congruency.

Since you already have <BAC and <EDC congruent to eachother, and sides BC and EC congruent to each other, you only need that one remaining angle in between. <ACB can be proven congruent to <DCE by the Vertical Angles Theorem, and that gives you the AAS you need to prove that these two triangles are congruent

Hope this helped.

Find the area of the shaded region
wariber [46]
31x^2 + 53x - 8



Use the FOIL method to find the area of the large rectangle. (7x - 2)(9 + 5x)

First term in each binomial: 7x * 9 = 63x
Outside terms: 7x * 5x = 35x^2
Inside terms: -2 * 9 = -18
Last term in each binomial: -2 * 5x = -10x

Now, just add them all up.

63x + 35x^2 - 8 - 10x

35x^2 + 53x - 8



Now find the area of the square.

2x * 2x = 4x^2



Now, subtract the areas.

31x^2 + 53x - 8

pshichka [43]

Answer:

Two-tailed test.

Step-by-step explanation:

There are two types of tests:

One-tailed tests and two-tailed tests.

When we only test if the mean is less or more than a value, we have a one-tailed test.

When we test if the mean is different from a value, we have a two-tailed test.

If you were to conduct a test to determine whether there is evidence that the proportion is different from 0.30, which test would you use?

Test if it is different, so a two-tailed test.
