Answer:
65.1 and 69.1
Step-by-step explanation:
a^2+b^2=c^2
c=95
b=a+4
Solve for a^2+(a+4)^2=95^2
a=65.1
b=a+4=69.1
The answer is the number that 'x' must be in order for
that equation to be a true statement. Here's one way
to find out what the number is:
x + 36 = 4x
Subtract 'x' from each side: 36 = 3x
Divide each side by 3 : 12 = x
The temperature of coffee 10 minutes after it was poured (120 F) will help in solving the constant “a”.
<span>120 = 120(2 ^ 10a) + 60 </span>
<span>2 ^ -1 = 2 ^ 10a </span>
<span>a = -1/10 </span>
<span>The temperature of coffee 30 minutes after it was poured is: </span>
<span>F = 120 ( 2 ^ -30/10) + 60 </span>
<span>F = 120 * 1/ 8 + 60 </span>
<span>F = 15 + 60 </span>
<span>F = 75</span>
<span>This is pretty easy, the answer is 124</span>
Since this can’t be factored easily, you have to use synthetic division. This makes the answer x+4+(-1/x+5)
