98-x2=0 solve this with the quadratic formula
Mars2501 [29]

Answer:

             x∈{-7√2, 7√2}

Step-by-step explanation:

98-x^2=0\\\\-x^2+98=0\\\\a=-1\,,\ \ b=0\,,\ \ c=98\\\\x_1=\dfrac{-0-\sqrt{0^2-4\cdot(-1)\cdot98}}{2\cdot(-1)}=\dfrac{-\sqrt{4\cdot49\cdot2}}{-2}=\dfrac{-2\cdot7\sqrt{2}}{-2}=7\sqrt2\\\\x_2=\dfrac{-0+\sqrt{0^2-4\cdot(-1)\cdot98}}{2\cdot(-1)}=\dfrac{2\cdot7\sqrt{2}}{-2}=-7\sqrt2

#12<br> The distance between the points (3, 3) and (7, 3) is
Marina CMI [18]

Solution:

We have been asked to find the distance between the points (3, 3) and (7, 3).

we can find the distance between the two points using the distance formula.

The distance formula is given as

D=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2} \\ \\ \text{where } (x_1, y_1) \ and  \ (x_2, y_2) \ are  \ two \ points\\

Now substitute the given values we get

D=\sqrt{(7-3)^2+(3-3)^2}\\ \\ \ D=\sqrt{4^2+0}=4\\

Hence the distance between the given points is 4

Find one value of x for which f(2) &amp; f(x)=4
igomit [66]
The first thing we must do for this case is to observe the value of the y coordinate for a given value of the x coordinate.
 We have then:
 f (x) = - 4: occurs when x = 0 
 On the other hand, for x = 2 we have:
 f (2) = - 2
 Answer:
 f (x) = - 4: occurs when x = 0
 
f (2) = - 2

Find the distance between (-4,2) and (10,2).
satela [25.4K]

Answer:

14

Step-by-step explanation:

1) To find the distance between two points you'll need to use the distance formula:

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

2) Figure out which points you'll want to set:

(x1,y1) = (-4,2) (x2,y2) = (10,2)

3) Substitute your values into the formula:

= \sqrt{(-4 - 10)^{2} + (2-2)^{2} }\\= \sqrt{(-14)^{2} + (0)^{2} }\\= \sqrt{196 }\\= 14
