Answer:
D. x=4
Step-by-step explanation:
We can solve this with the Pythagorean Theorem for the right triangle that we can see (which is half of the triangle).
The bottom length is 3 and the hypotenuse is 5.
The Pythagorean Theorem is a²+b²=c².
We can plug this in:
3²+x²=5²
9+x²=25
x²=16
x=4
Answer:
C. The situation represents a geometric sequence because the successive y-values have a common ratio of 1.05.
Step-by-step explanation:
The initial number of accidents = 5200 = Po
It increases 5% every year.
So r = 5% = 0.05
y = Po(1 + r)^x
y = 5200(1 + 0.05)^x
y = 5200(1.05)^x
This sequence is an exponential. Which is a geometric sequence.
Answer: C. The situation represents a geometric sequence because the successive y-values have a common ratio of 1.05.
Thank you.
Answer:
x=2
Step-by-step explanation:
To solve, we need to isolate the variable (x)
To do this, we must get all the variables to one side of the equation, and all the numbers to the other
3x+3= -2x+13
Add 2x to both sides to "reverse" the subtraction
5x+3=13
Subtract 3 from both sides to "reverse" the addition
5x=10
Divide both sides by 5 to "reverse" the multiplication
x=2
