Step-by-step explanation:
We have an isosceles triangle:
The length of the sides are:
side₁=side₂=x
side₃=(x+x)-3=2x-3
Perimeter of a triangle=is the sum of the all sides.
we have this equation:
x+x+(2x-3)=29
4x=29+3
4x=32
x=32/4
x=8
The length of the third triangle will be: 2x-3=2*8-3=16-3=13
Answer: The length of the longest side of the triangle would be 13 meters.
Equation of the line in point slope form is y + 3 = -1/2(x - 7)
Step-by-step explanation:
- Step 1: Given slope of the line is -1/2 and passes through the point (x1, y1) = (7, -3). Equation in point slope form is y - y1 = m(x - x1)
⇒ y - (-3) = -1/2(x - 7)
⇒ y + 3 = -1/2(x - 7)
Answer:
The population size after seven days will be 171.
Step-by-step explanation:
The population of protozoa can be modeled by the following equation.
In which Q(t) is the population after t days, Q(0) is the initial population and r is the growth rate.
In this problem, we have that:
So
Find the population size after seven days.
This is Q(7).
The population size after seven days will be 171.
C 13.5% because when you add the numbers together and use the percentage rule to divide it it equals a 13.5 percent
