The price of a coat increased from $78 to $92. What is the price increase percentage?

svetlana [45]

Answer:

18%

Step-by-step explanation:

Percent change can be found using the following formula:

$\frac{original-new}{original}*100$

Original represents the initial cost where new represents the new cost. We multiply the answer by 100 to get the percentage:

$\frac{92-78}{78}*100$ = 18%

(1 point) The length of an insect (L, in mm) is a function of the temperature during development (T , measured in ∘C according t

lawyer [7]

Answer:

$M(T)=1.1(7(8+T^{10})^{3})$ and $M(T)=1.1(7(8+22^{10})^{3})=1.44\time10^{41}$

Step-by-step explanation:

We have the next set of functions:

$L(T)=8+T^{10}$

$V(L)=7L^{3}$

$M(V)=1.1V$

We want to know M(T) then:

$M(V)=1.1V$ but we know that $V(L)=7L^{3}$ :

$M(L)=1.1(7L^{3})$ and we know that $L(T)=8+T^{10}$

$M(T)=1.1(7(8+T^{10})^{3})$

Finally using the value of 22º we have

$M(T)=1.1(7(8+22^{10})^{3})=1.44\time10^{41}$

Find A={a,b,c} then find A*A.

Alenkasestr [34]

Assuming you want to do a cartesian product, then you basically form items (x,y) such that x is in set A, and y is in set A

More generally, A * B will consist of items of the form (x,y) such that x is in A and y is in B. However, we have B = A.

So,

A * A = {

(a,a), (a,b), (a,c)

(b,a), (b,b), (b,c)

(c,a), (c,b), (c,c)

}

I broke things up into separate rows to show that we can form a 3x3 table. Each row is a different x value from the set {a,b,c}. Each column is a different y value from the set {a,b,c}

In my opinion, this helps organize things much better than rather have it all on one single line like this

A * A = { (a,a), (a,b), (a,c), (b,a), (b,b), (b,c), (c,a), (c,b), (c,c) }

which in all honesty looks like a bit of a cluttered mess.
