If f(x) = 2x2 + 1 and g(x) = x2 – 7, find (f – g)(x).
nadya68 [22]

Answer:  The required value is

(f-g)(x)=x^2+8.

Step-by-step explanation: The given functions are:

f(x)=2x^2+1,\\\\g(x)=x^2-7.

We are given to find the value of (f-g)(x).

We know that, if s(x) and t(x) are any two functions of a variable x, then we have

(s-t)(x)=s(x)-t(x).

Therefore, we have

(f-g)(x)\\\\=f(x)-g(x)\\\\=(2x^2+1)-(x^2-7)\\\\=2x^2+1-x^2+7\\\\=x^2+8.

Thus, the required value is

(f-g)(x)=x^2+8.

What is true regarding two adjacent arcs created by two<br> intersecting diameters?
Juli2301 [7.4K]

Given:

Two diameters intersect each other.

To find:

The correct statement regarding two adjacent arcs created by two  intersecting diameters.

Solution:

We know that, two diameter intersect each other at origin and measure of arc is equal to the corresponding angle generated by the intersection of diameters.

If two lines intersect each other then we get 4 angles and sum of any two adjacent angles is 180°.

It means the sum of any two adjacent central angles generated by the intersection of diameters is 180°.

So, the sum of two adjacent arcs created by two  intersecting diameters is 180°.

Therefore, the correct option is C.

Emily meal cost 32.75 and Darren's meal cost 39.88 . Emily treats Darren by paying for both meals,and leaves 14% tip. Find the t
tia_tia [17]
32.75 + 39.88   = 72.63

72.63 x 114%  = 72.63 x 1.14  = $82.7982   or $82.80 to the nearest cent.

114%  is all of the cost of the meal plus 14 % extra for the tip.  See how muliplying by 1.14 includes the $72.63  (this saves the step of adding it on at the end if you were only to find 14% of $72.63)
