pashok25 [27]

Answer:  g(f(0)) = 2 and  (f ° g)(2) = -3.

Step-by-step explanation:  We are given the following two functions in the form of ordered pairs :

f = {(-2, 3), (-1, 1), (0, 0), (1,-1), (2,-3)}

g = {(-3, 1), (-1, -2), (0, 2), (2, 2), (3, 1)} .

We are to find g(f(0))  and   (f ° g)(2).

We know that, for any two functions p(x) and q(x), the composition of functions is defined as

(p\circ q)(x)=p(q(x)).

From the given information, we note that

f(0) = 0,  g(0) = 2,  g(2) = 2  and  f(2) = -3.

So, we get

g(f(0))=g(0)=2,\\\\(f\circ g)(2)=f(g(2))=f(2)=-3.

Thus,  g(f(0)) = 2 and  (f ° g)(2) = -3.

The values of x and y are directly and one pair of values are given.
Anestetic [448]

Answer:

The relation is y = -1.5x

Step-by-step explanation:

x and y are directly proportional:

This means that the equation is given by:

y = ax

In which a is the multiplier that relates these two variables.

x= -4, y =6

We use this to find a. So

y = ax

6 = -4a

a = -frac{6}{4}

a = -1.5

So

The relation is y = -1.5x

Help pls so people say it’s none of these but idk I am confused.
crimeas [40]

Answer:

Volume = \pi r^2 h

2512 = 3.14 × r^2 × 8

r^2 = \displaystyle\frac{314}{3.14}

r^2 = 100

r = 10 \ cm

Diameter = 2r = 20 \ cm

Dont get confused try to understand : )

X=4y+2 in slope intercept form
siniylev [52]
Answer:
The slope intercept form is y=mx+c
So,
x=4y+2 should also be made in that form
x-2=4y
y=(x-2)/4
That’s the final answer in slope intercept form
