Answer:

Of course there is no way for them to be both correct, since they contradict each other. Please make me brainliest

Step-by-step explanation:

Suppose that a polynomial has four roots: s, t, u, and v. If the polynomial were evaluated at any of these values, it would have to be zero. Therefore, the polynomial can be written in this form.This polynomial has a degree of at least 4. It therefore cannot be cubic.

seropon [69]

Answer:

3c-6

Step-by-step explanation:

One day is c-2 so we need to multiply by 3. We get 3(c-2) or 3c-6.

Tip: use the variables/numbers in the problem to form an equation. Then, simplify.

The equation of circle having a diameter with endpoints (-2, 1) and (6, 7) is

densk [106]

Answer:

$(x-2)^{2}+(y-4)^{2}=25$

Step-by-step explanation:

step 1

Find the diameter of the circle

the formula to calculate the distance between two points is equal to

$d=\sqrt{(y2-y1)^{2}+(x2-x1)^{2}}$

$A(-2,1)\\B(6,7)$

substitute the values

$d=\sqrt{(7-1)^{2}+(6+2)^{2}}$

$d=\sqrt{(6)^{2}+(8)^{2}}$

$d=\sqrt{100}$

$d=10\ units$

The radius is half the diameter

$r=10/2=5\ units$

step 2

Find the center of the circle

the center of the circle is the midpoint between the endpoints of the diameter

The center is

$(\frac{-2+6}{2},\frac{1+7}{2})$

$(2,4)$

step 3

Find the equation of the circle

The equation of the circle is

$(x-h)^{2}+(y-k)^{2}=r^{2}$

substitute the values

$(x-2)^{2}+(y-4)^{2}=5^{2}$

$(x-2)^{2}+(y-4)^{2}=25$

Write the whole number that correctly completes the word problem:

irina1246 [14]

Answer:

2/3(two thirds) of the 24 hour day awake, amounts to 24 x 2 / 3 hours awake which is equal to 16 hours awake

Step-by-step explanation:

24 x 2/3

there are many ways to evaluate this mentally, if you know 8x3=24, for instance you can multiply top and bottom of 2/3 by 8 yo gey 24 x 16/24 which is 16 hours
