Answer:
sin s = 36 / 42 = 18 / 21 = 6/ 7
sin R = 14 / 42 = 7 / 21 = 1 / 3
cos s = 14 / 42 = 1 / 3
cos R = 36 / 42 = 6 / 7
<span>You are given the word alabama and you are asked to find how many distinguishable 7 letter "words" can be formed from it.
ALABAMA has seven letters so we will start at 7!
Counting the number of A's in the word we have 4 A's and so we will divide it by 4!
</span>Counting the number of L's in the word we have 1 L and so we will divide it by 1!
Counting the number of B's in the word we have 1 B and so we will divide it by 1!
Counting the number of M's in the word we have 1 M and so we will divide it by 1!
And so the number of ways is 7! / (4! x 1! x 1! x 1!) = 210 words.
The answer for the first box is 90
Why? Because this is from the expression 90x+1500. The 90x means the slope is 90. So each time x goes up by 1, the value of y goes up by 90
----------------------------
The answer to the second box is 1500
If you were to plug in x = 0, then
y = 90x+1500
y = 90*0+1500
y = 1500
So he earns $1500 for selling 0 copies
3 x^{2} - 15x - 42
(x-7)(x+2)
x-7=0 x+2=0
x=7,-2
<span> An </span>equation<span> is a mathematical statement that shows the equal value of two expressions while an </span>inequality is a mathematical statement that shows that an expression is lesser than or more than the other. "<span>An 18-wheel truck stops at a weigh station before passing over a bridge. The weight limit on the bridge is 65,000 pounds. The cab (front) of the truck weighs 20,000 pounds, and the trailer (back) of the truck weighs 12,000 pounds when empty. In pounds, how much cargo can the truck carry and still be allowed to cross the bridge?" does this help?</span>
