Answer:
Measure the length and width of the splatter. Divide the width of the splatter by its length.
Answer: The car is 6.6 years old.
Step-by-step explanation:
Hi, to answer this question we have to replace the values in the equation given:
Y = 1/2 (half the value)
A = 1 (total value)
r =10% = 0.10 (decimal form)
Replacing:
y = A(1-r)^t
1/2 = 1 (1-0.10)^t
Solving for t:
(1/2)/1 = 0.9^t
1/2 = 0.9^t
log 1/2 = log 0.9^t
log 1/2 = (t) log 0.9
(log 1/2)/ log 0.9 = t
6.57 =t
6.6 years (rounded)

Step-by-step explanation:
The answer would be: <span>a. y=4x+2

In this question, the table is made from an equation that follows y=ax+b. To find the equation, it would be easier to use x=0 so you can exclude the a value and find the value of b. From the description, you can find that x=0 will result in y=2. Then if you put it into the equation:
y=ax+b
2=a(0)+b
b=2
Now we need to find the value of a. You can do this by inserting any value of x and y beside x=0. Let's try to use x=-2 and y=-6
y=ax+b
-6 =a(-2)+2
-6= -2a+2
-2a= -6-2
-2a=-8
a= -8/-2=4
The equation would be:
y=4x+2
