Let's take this step by step. First, let's find the area of the triangle:
A_t = \frac{1}{2}bh = \frac{1}{2}(13-7)(4+4)= \frac{1}{2}(6)(8) = 24cm^2

Small rectangle:
A = lw = 7*4 = 28cm^2

Big rectangle:
A = lw = 10*4 = 40 cm^2

Let's add all the areas up:
A_T = 24+28+40 = 92cm^2

So, your answer is: The area of this figure is 92 cm².

Answer:

Point Slope: (y-(-1)=3(x-4)

Step-by-step explanation:

y-y1=m(x-x1) Point Slope Form\\plug in:\\y-(-1)=3(x-4)\\

Slope Intercept is y=mx+b\\Find Y Int (b):\\b=-13\\Plug in;\\y=3x-13

A bacteria sample can be modeled by the function f(x) - 350(1.20) which gives the number of bacteria in the sample at the end of
marissa [1.9K]

Answer: A) The initial number of bacteria is 350.

Step-by-step explanation:

Exponential growth equation: f(x)=A(1+r)^x , where A=Initial value, r= growth rate.          (i)

Given: A bacteria sample can be modeled by the function f(x) = 350(1.20)which gives the number of bacteria in the sample at the end of x days.

Here, f(x)=350(1+0.20)

Compare this equation to  (i) , we get A = 350 and r= 0.20 = 20% (growth rate)

So, the  best interpretation of one of the values in this function are:

A) The initial number of bacteria is 350.
