Write 129.701 in expanded form

2 answers:

7 0

129.701 in expanded form:

100 + 20 + 9 + (7 x 1/10) + (1 x 1/1000)

1 is in the hundreds place so 1 x 100 =     100
2 is in the tens place so 2 x   10 =    20
9 is in the ones place   so 9 x   1 =   9
7 is in the tenths place   so 7 x 1/10 = 0.7
1 is in the thousandths place so 1 x 1/1000 = 0.001

The equation of a parabola is (y−3)2=20(x+1) .

Andreyy89

2(y - 3) = 20(x - 1)
(h, k) = (1, 3)
(y - 3) = 10(x - 1)
4p = 10
p = $\frac{5}{2}$
x = h - p
x = 1 - $\frac{5}{2}$
x = - $\frac{3}{2}$
Hope that helped! If it's wrong, I'm sorry; I only learned about directrix today.

Let P={ 1,2,3,5,7,9}, Q= { 1,2,3,4,5}, and R= {2,3,5,7,11} Find P n R?

Sloan [31]

Answer:

$P \cap R=\{2,3,5,7\}$

Step-by-step explanation:

Given : Let P={ 1,2,3,5,7,9}, Q= { 1,2,3,4,5}, and R= {2,3,5,7,11}

To find : The value of $P \cap R$ ?

Solution :

The intersection of two sets is defined as the set of their common elements or the elements appear in both the sets.

The sets are P={ 1,2,3,5,7,9} and R= {2,3,5,7,11}

Common elements in P and R are {2,3,5,7}

So, $P \cap R=\{2,3,5,7\}$

Therefore, The value of $P \cap R=\{2,3,5,7\}$

Instructions: Given the vertex of a quadratic function, find the axis

allsm [11]

The axis of symmetry is x = 5.

In first place, every quadratic function can be expressed as follows:

f(x) = a*x² + b*x + c

where a, b and c are real numbers and a ≠ 0. This way of writing the quadratic function is called polynomial.

The graph of a quadratic function is a parabola. Every parabola is a symmetric curve with respect to a horizontal line called the axis of symmetry. That is, the axis of symmetry is an imaginary line that passes through the middle of the parabola and divides it into two halves that are mirror images of each other.

The point of intersection of the axis of symmetry with the parabola is called the vertex, and it divides the parabola into two branches. That is, the axis of symmetry always passes through the vertex of the parabola. The x-coordinate of the vertex is the equation of the axis of symmetry of the parabola.

Then, being the vertex of the quadratic function (5,7), where the vertex on the x-axis has a value of 5 and on the y-axis a value of 7, the axis of symmetry is x = 5.

Jada solved the equation below what was jada’s error ?

Pani-rosa [81]

Answer:

Jada should have multiplied both sides of the equation by 108.

Step-by-step explanation:

The goal of any equation is to isolate and solve for the variable. In the case of the proportion given, the variable in the form of a fraction. In order to get the 'x' by itself, you need to complete the inverse (opposite) of division, which is multiplication, to remove the denominator of '108.'

$(\frac{108}{1})-\frac{4}{9}=\frac{x}{108}(\frac{108}{1})$

$-\frac{432}{9}=x$

-48 = x
