Arisa [49]

Since multiplication is commutative, we can rearrange the problem:
$(1.12*10^5)(6.06*10^5) = (1.12*6.06)(10^5*10^5)$
Using the properties of exponents, we have:
$(1.12*6.06)(10^10)
\\=6.7872*10^10$

Again, multiplication is commutative, so we rearrange the problem; then we use the product property of exponents:
$(2*10^1)(3*10^1)
\\=(2*3)(10^1*10^1)
\\=6*10^2$

$(2.775*10^-^4)(4.775*10^4)
\\=(2.775*4.775)(10^-^4*10^4)
\\=(2.775*4.775)(10^0)
\\=(2.775*4.775)(1)
\\=2.775*4.775=13.250625=1.3250625*10^1$

$5(8.14*10^2)=(5*8.14)(10^2)=40.7*10^2=4.07*10^3$

For for each quadratic function below use method of completing the Square or averaging the x-intercept to write the equation in

lions [1.4K]

We have the expressions:

$f(x)=x^2+6x+15$ $y=x^2-4x+9$ $f(x)=x^2-8x$ $y=x^2+7x-2$

Now, with this we operate as follows:

$f(x)=x^2+6x+15=x^2+6x+9+15-9$ $\Rightarrow(x+3)^2+6$

Then, the axis is x = -3 and the vertex (-3, 6)

$y=x^2-4x+9=x^2-4x+4+9-4$ $\Rightarrow(x-2)^2+5$

Then, the vertex is (2, 5) and the axis is x = 2.

$f(x)=x^2-8x+4-4\Rightarrow(x-2)^2-4$

Then, the vertex is (2, -4) andd the axis is x = 2.

$y=x^2+7x-2=x^2+7x+\frac{49}{4}-2-\frac{49}{4}$ $\Rightarrow(x+\frac{7}{2})^2-\frac{57}{4}$

Then, the vertex is (-7/2, -57/4) and the axis is -7/2.

Terrence says pi is a rational number since it is the ratio of a circle's circumference to its diameter. Why is

kari74 [83]

Answer:

(A) Pi cannot be written as a ratio of integers even if it represents a different ratio.

Step-by-step explanation:

A rational number is can be expressed as the quotient of two integers. It can either be a number with or without a decimal part when converted to decimals.
