Select the true statement. A. Neither function is even. B. Only function f is even. C. Only function g is even. D. Both function
astraxan [27]

Answer:

The answer is "Option C".

Step-by-step explanation:

The graph of the even function will have both ends pointed in the same direction, while the graph of the odd function will have both ends pointed inside the reverse way. Furthermore, as the y-axis approaches, and also regular expression graph becomes symmetric. The graph of an unusual function, on either hand, is symmetric around the origin and also has rotational symmetry around the origin. They could see that the graph of function g meets a function requirement by looking at it. That graph of function f, but on the other hand, is not symmetric about its y-axis, implying that function f is not even. As both a result, g is a function that is even.

Solve the equation. Find x.<br> 20x + 5 - 0 = 5x + 32.5*2
SVEN [57.7K]

Answer:

x = 4

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

20x+5−0=5x+(32.5)(2)

20x+5+0=5x+65

(20x)+(5+0)=5x+65(Combine Like Terms)

20x+5=5x+65

20x+5=5x+65

Step 2: Subtract 5x from both sides.

20x+5−5x=5x+65−5x

15x+5=65

Step 3: Subtract 5 from both sides.

15x+5−5=65−5

15x=60

Step 4: Divide both sides by 15.

15x

15

=

60

15

x=4

Hope this helps!

A cone has radius 9 and height 12. A frustum of this cone has height 4.
Rom4ik [11]

The radii of the frustrum bases is 12

Step-by-step explanation:

In the figure attached below, ABC represents the cone cross-section while the BCDE represents frustum cross-section

As given in the figure radius and height of the cone are 9 and 12 respectively

Similarly, the height of the frustum is 4

Hence the height of the complete cone= 4+12= 16 (height of frustum+ height of cone)

We can see that ΔABC is similar to ΔADE

Using the similarity theorem

AC/AE=BC/DE

Substituting the values  

12/16=9/DE

∴ DE= 16*9/12= 12

Hence the radii of the frustum is 12

Which statement best describes f(x) = -2 times the square root of x-7+1
BigorU [14]

Answer:

f(x) = -2*sqrt(x - 7 + 1)

Step-by-step explanation:

If by "statement" you mean equation, then it's pretty self-explanatory. Sorry if I'm confused though, you probably didn't list the proper choices.
