Answer:
Step-by-step explanation:
since the triangle is a 30-60-90 triangle:
√3 : 2 = x : 9
=> 2x = 9 √3
=> x =
Answer:
A) Exponential decay, 55% decrease
Step-by-step explanation:
The <em>b</em><em> </em>is less than 1, so that means it's decaying. Since <em>b</em><em> </em>= 0.45 and that the formula for an exponential decay is <em>a</em>(1- percent in decimal form)^x, all you have to do is find out what the decimal was BEFORE you subtracted it from 1.
So: 1 - x = 0.45
x = 0.55
0.55 = 55%
Answer:
x = 19
Step-by-step explanation:
x +(-14)= 5
we start by multiplying the + and the - in the bracket which gives you -
posiyive x negative = negative
x - 14 = 5
the -14 crosses the equal sign and becomes +14
x=5 +14
x = 19
