Brissa's desk is 3 feet long. About how long is it in meters? use 1 foot = 0.305 meter

Which equation represents a parabola that opens upward, has a minimum value of 3, and has an axis of symmetry at x= 3?

Ilya [14]

Answer:

$y=(x-3)^2+3$

Step-by-step explanation:

The correct question is

Which equation represents a parabola that opens upward, has a minimum value of y=3, and has an axis of symmetry at x= 3?

Verify each case

case 1) we have

$y=(x+3)^2-6$

This a vertical parabola open upward (the leading coefficient is positive)---> is ok

The vertex represent a minimum ---> is ok

The vertex is the point (-3,-6)

The minimum value of y=-6 ----> is not ok

The axis of symmetry is x=-3 ----> is not ok

case 2) we have

$y=(x+3)^2+3$

This a vertical parabola open upward (the leading coefficient is positive)---> is ok

The vertex represent a minimum ---> is ok

The vertex is the point (-3,3)

The minimum value of y=3 ----> is ok

The axis of symmetry is x=-3 ----> is not ok

case 3) we have

$y=(x-3)^2-6$

This a vertical parabola open upward (the leading coefficient is positive)---> is ok

The vertex represent a minimum ---> is ok

The vertex is the point (3,-6)

The minimum value of y=-6 ----> is not ok

The axis of symmetry is x=3 ----> is ok

case 4) we have

$y=(x-3)^2+3$

This a vertical parabola open upward (the leading coefficient is positive)---> is ok

The vertex represent a minimum ---> is ok

The vertex is the point (3,3)

The minimum value of y=3 ----> is ok

The axis of symmetry is x=3 ----> is ok

Which statement is true?

defon

Answer:

b. Multiplying decimals less than one is finding a part of a part.

Step-by-step explanation:

A part of a given number implies a selected part of a given number which can be expressed as a fraction of the number. Example, the half of any number is $\frac{1}{2}$ .

The product of a part and another part can be expressed as;

$\frac{1}{3}$ x $\frac{2}{3}$ = $\frac{2}{9}$

or,

$\frac{1}{2}$ x $\frac{1}{2}$ = $\frac{1}{4}$

or,

$\frac{1}{2}$ x $\frac{2}{3}$ = $\frac{2}{6}$ = $\frac{1}{3}$

The three examples shows: a part x a part.

Therefore, it would be observed that multiplying decimals less than one is the same as finding a part of a part.

What is the m Show work

Ghella [55]

Answer:

measure of angle A is 80 degree.

Step-by-step explanation:

isosceles triangle will have same base angles

first base angle is 50, and the second will also be 50

3 angles of a triangle will add up to be 180 degree.

A is the vertex angle.

So 50 + 50 + A = 180

100 + A = 180

A = 80.
