Answer:

the answer is 36654.52

Step-by-step explanation:

alright so if there are 86400 seconds in a day we substract 28800 bc thats how many seconds we have in 8 eight hours. That is 57600. divide it by 22, which is 2618.18. And multiply it by 14 bc thats how many times he blinks in 22 seconds. 36654.52

Step-by-step explanation:

24hours=86400seconds

8hours =28800seconds

Sam sleeps for 28800second

so 86400-28800=57600seconds.

Sam is awake for 57600seconds.

14blinks in 22seconds

xblinks in 57600seconds.

cross multiply

we have

22x = 806400

x=36654.5

Sam blinks for 36654.5 in a day

What is the solution to this matrix equation?[ -1 4 3 2] [x y] = [-26 8] i need to find (x=?) and (y=?)

Ghella [55]

Answer:

x: $\frac{26}{3y}$

y: $\frac{26}{3x}$

Part A: Finding X

Simplify the equation.

$-4*3*(2xy)=-26*8\\-12*(2xy)=-26*8\\-24*(xy)=-26*8\\-24*xy=-26*8\\-24*xy=-208$

Divide terms.

$\frac{(-24 * (xy))}{-24y}\\\\Cancel~"-24"\\\\\frac{(-24) * xy}{(-24)y} \\= \boxed{\frac{-208}{-24y}}\\\\\\Cancel~"y"\\\\\frac{x(y)}{(y)} = \boxed{\frac{-208}{-24y} }\\x \div 1 = \frac{-208}{-24y}$

Factor -8.

$x = \frac{-8(26)}{-24y}(Cancel~"-8")\\x = \frac{26}{3y}$

Part B: Finding Y

Simplify.

$-4*3*(2xy)=-26*8\\-12*(2xy)=-26*8\\-24*(xy)=-26*8\\-24*xy=-26*8\\-24*xy=-208$

Divide.

$\frac{(-24*(xy))}{-24x} = \frac{-208}{-24x}\\\\Cancel~"-24"\\= \frac{xy}{x} = \frac{-208}{-24x}\\\\Cancel~"x"\\= \frac{-208}{-24x}$

Factor.

$y = \frac{-8(26)}{-24x}\\y = \frac{-8(26)}{-8(3x)} (Cancel -8)\\y = \frac{26}{3x}$

Consider the function f (x) = x2.

klio [65]

Answer: The graph is shifted 2 units to the right.

Step-by-step explanation:

Given a function f(x), we know that one transformation rule is:

If $f(x-k)$ then the function is shifted "k" units to the right.

Therefore, for the function $f(x)=x^{2}$ , when we subtract 2 from the input, then we get the function g(x) in the form:

$g(x)=(x-2)^{2}$

We can conclude that subtracting 2 from the input of the function $f(x)=x^{2}$ , then the graph is shifted 2 units to the right.

dem82 [27]

Answer:

The first set (A)

Step-by-step explanation:

The five inputs are {-12, -3, 0, 3, 12}. The first set (A) includes all five of these inputs and a single output for each of them: {(-12, -18), (-3, -3), (0, 2), (3, 7), (12, 22).
