Answer:

B.) why Factor p+ 12r - 6, I did not do that below.

Step-by-step explanation:

r^2+12r-6=0

solve:

r^2 + 12 r + 36 - 36 - 6 = 0

factor the trinomial by completing the square.

( r + 6)^2 -42 = 0

(r + 6)^2 = 42

r + 6 = root(42 ) or r + 6 = - root(42)

r = -6 + root(42) or r = -6 -root(42)

Select the simplification that accurately explains the following statement.

lutik1710 [3]

Answer:

Option (b) is correct.

$(2^\frac{1}{4} )^4=2^\frac{1}{4} \times 2^\frac{1}{4}\times 2^\frac{1}{4}\times 2^\frac{1}{4}=2^{(\frac{1}{4}+ \frac{1}{4}+ \frac{1}{4}+ \frac{1}{4} )}=2^{1}=2$

Step-by-step explanation:

Given: $(2^\frac{1}{4} )^4$

We have too choose the correct simplification for the given statement.

Consider $(2^\frac{1}{4} )^4$

Using property of exponents, $(a^m)^n=a^m\times a^m\times a^m\times ....\times (n\ times)$

We have,

$(2^\frac{1}{4} )^4=2^\frac{1}{4} \times 2^\frac{1}{4}\times 2^\frac{1}{4}\times 2^\frac{1}{4}$

Again applying property of exponents $a^m\times a^m=a^{n+m}$

We have,

$(2^\frac{1}{4} )^4=2^{(\frac{1}{4}+ \frac{1}{4}+ \frac{1}{4}+ \frac{1}{4} )}$

Simplify, we have,

$(2^\frac{1}{4} )^4=2^{\frac{4}{4}}$

we get,

$(2^\frac{1}{4} )^4=2^{1}=2$

Thus, $(2^\frac{1}{4} )^4=2$

Option (b) is correct.

Give the center and radius of the circle x2+y2=25

Arisa [49]

Answer:

B) (0,0); r=5

Step-by-step explanation:

A circle's standard form is (x-h)^2+(y-k)^2=r^2

The center is (h, k) and the radius is r.

So, here the center would be (0, 0) and the radius would be square root 25, or 5.

Which graph best represents the function f(x) = 2x^2 -2

astraxan [27]

Answer:

The u equation, a parabola

Step-by-step explanation:

This is a quadratic equation, since we have a variable 'x' raised to second power.

The vertex can be found using the formula x=-b/2a when the parabola is written as y=ax2 + bx +c.
