Answer with explanation:

→Triangle DEC equals about Triangle B EC.

⇒The meaning of equal here,is that both the triangles that is, ΔDEC ≅ ΔB EC.

≡When Triangles are congruent,their corresponding sides and angles are equal .

Corresponding Sides which are equal by C P C TC:

1. BE = DE

2.BC =CD

3.EC, is Common.

Corresponding angles which are equal by C P C TC are:

1. ∠B EC=∠DEC

2. ∠ D CE=∠B CE

3.∠ E B C= ∠ E D C

Option A: ⇒Angle E BC equals about angle E DC

D. Line AE equals about line ED because if you measure line AE it is the same length as line ED

A farmhouse shelters 11 animals. Some are goats and some are ducks. Altogether there are 34 legs. How many of each animal are th

andriy [413]

We are given that there are 11 animals with a total of 34 legs.

Let G = number of Goats, and D = number of Ducks

then G + D = 11; solving for G, we get G = 11 - D

then, 4G + 2D = 34

substituting the value for G, we get 4(11 - D) + 2D = 34

expanding, we get 44 - 4D + 2D = 34

solving, we get D = 5. Therefore, G = 6

Proof: (5 x 2) + (6 x 4) = 34

Answer:

The values in the table, taking into account the quadratic equation, are:

x -3 -2 -1 0 1 2 3 4
y 16 9 4 1 0 1 4 9

Step-by-step explanation:

To obtain the values of the table, you must use the quadratic equation given:

y = x^2 - 2x + 1

Now, you must replace the x with the one that is above the value you want to find, in the first case, we're gonna replace the value x with -3:

y = x^2 - 2x + 1
y = (-3)^2 - 2*(-3) + 1
y = 9 + 6 + 1
y = 16

When x is -1

y = x^2 - 2x + 1
y = (-1)^2 - 2*(-1) + 1
y = 1 + 2 + 1
y = 4

When x is 1

y = x^2 - 2x + 1
y = (1)^2 - 2*(1) + 1
y = 1 - 2 + 1
y = 0

When x is 3:

y = x^2 - 2x + 1
y = (3)^2 - 2*(3) + 1
y = 9 - 6 + 1
y = 4

At last, the graph must be as the attached picture I give you, but remember in y-axis you must use 1 cm as unit and in the x-axis you must use 2 cm as unit, in this form, the graph will not be so elongated as the picture I attach, It would be wider.

(3x^4y^5) ^ 3/7 in radical form

kobusy [5.1K]

The expression in radical form is $(\sqrt[7]{3x^4y^5}) ^3$

In order to express the given indices expression in radical form, we need to ensure there is a square root present in the resulting expression.

According to the law of indices,

$a^{m/n} = \sqrt[n]{m}$
