Answer:

6 7/12

Step-by-step explanation:

We need to get a common denominator, which is 12

12 1/4 - 5 2/3

12 1/4*3/3 - 5 2/3*4/4

12 3/12 - 5 8/12

We will need to borrow from the 12 since 3/12 is less than 8/12. Write the 1 we borrow as 12/12

11 + 12/12 + 3/12 - 5 8/12

11 15/12 - 5 8/12

6 7/12

the diameter of the a sphere is increading at the rate of 2cm. per minute. Find the rate of change of the radius

____ [38]

So...the diameter is increasing at a rate if 2cm/minute, therefore the radius (1/2 the diameter) is increasing at half the rate. You will learn how to calculate the rate of change at a specific point in time in calculus.

Represent the following sentence as an algebraic expression, where "a number" is the letter x. You do not need to simplify.

My name is Ann [436]

<h3>Answer: (2x)^3</h3>

Work Shown:

x = some unknown number

2x = twice the number

(2x)^3 = cubing the previous result

If you want to simplify this expression, then you would get 8x^3 since 2^3 = 8.

Using the given information, give the vertex form equation for each parabola.

ollegr [7]

Answer:

Step-by-step explanation:

If you plot this point and the directrix on a coordinate plane, you can see that the directrix is 1/4 of a unit below the vertex. Since, by nature, a parabola opens in the direction opposite the directrix and "hugs" the focus, this is a positive x-squared parabola (meaning it opens upwards). The formula for this type of a parabola is, in vertex form,

$4p(y-k)=(x-h)^2$

where p is distance (in units) between the vertex and the directrix and h and k are the coordinates of the vertex. For us, p = .25, h = 7, and k = -6. Filling in our formula:

$4(.25)(y+6)=(x-7)^2$

Simplify the left side to

$1(y+6)=(x-7)^2$ which simplifies, in its entirety, to

$(x-7)^2-6=y$
