Answer: The least possible value of k is -6.

Step-by-step explanation:

Let 'k' be the negative even integer that is greater than -7.86 .

On number line, -7.86 lies between -7 and -8 such that

-7 > -7.86 > -8

So, -7 is the least integer that is greater than -7.86.

Since, -6 > -7 . That means -6 is the least negative even integer that is greater than -7.86 .

Hence, the least possible value of k is -6.

Find the measure of arc DF (with an explanation of how to solve please!)

allochka39001 [22]

Answer:

mDF = 90°

(Assuming arc mCE is 5x + 10)

Step-by-step explanation:

When we have two chords crossing in a circle, there is a property where the angle in the cross point is equal half the sum of the corresponding arcs.

So in this case, we have:

70° = (mCE + mDF)/2

Assuming mCE is 5x + 10, we have:

70 = (5x + 10 + 11x + 2)/2

70 = (16x + 12)/2

70 = 8x + 6

8x = 64

x = 8

So the arc mDF is:

mDF = 11x + 2 = 11 * 8 + 2 = 90°

Answer:

3 a²b

Step-by-step explanation:

This is what I did:

3 a²b ( 5b² - 7a²)

when you try to expand this, it will give you back the original expansion so 3a²b is the greatest common factor

borishaifa [10]

Answer:

p, m, n.

Step-by-step explanation:

It is given that,

$n=p(m)$

Here, p is the name of the function and its variable is m which is independent.

Independent variable : Whose value does not depend on another variable.

Dependent variable : whose value depends on the another variable.

Since the value of n depends on the value of p(m) which is a function of m, therefore n is a dependent variable which depends on the variable m.

∴ If n = p(m), p is the function name, m is the independent variable, and n is the dependent variable.
