Step-by-step explanation:

let's say, 7 - 4 = 3

that contradicts the statement that both numbers are odd.

no, they are 7, 4, with 4 being even (and not odd).

in fact, as with sums and subtractions in general, it requires an odd and an even number to produce an odd result.

odd with odd always delivers an even result. as does even with even.

Let f(x) = 4x + 3 and g(x) = -2x + 5. Find.(f o g) (5)

daser333 [38]

<span>f(x) = 4x + 3
g(x) = -2x + 5

(f o g) (5) means the function of g when g is a function of 5
(the function of the function concept)

so we need to get g(5) firstly

</span>
<span>g(x) = -2x + 5
g(5)= -2(5) + 5 = -5

After that, f(g(5)) = f(-5) = 4(-5) + 3 = -20 + 3 = -17

I hope that helps

Answer:

The direct distance between the birds is 12.64 miles.

Step-by-step explanation:

We have, one bird flew 12 miles west and another bird flew 4 miles north. It is required to find the direct distance between the birds. It means we need to find the resultant of two displacement. It can be given by :

$d=\sqrt{12^2+4^2} \\\\d=12.64\ \text{miles}$

So, the direct distance between the birds is 12.64 miles.

Using the formula in model 1, choose the correct answers for the new balance and amount of interest earned in the following comp

melisa1 [442]

To find the total amount
The formula is
A=p (1+r)^t
A total amount?
P present value 1050
R interest rate 0.06
T time 25 years
A=1,050×(1+0.06)^(25)=4,506.46

Interest amount
I=A-p
I=4,506.46−1,050
I=3,456.46
