Answer:
9/35ths of the total amount
Step-by-step explanation:
essentially, we are finding 3/5ths of 3/7ths
"of" in math is an indication to multiply
so,
× =
9/35ths of the total amount of vehicles are red cars.
Answer:
(b) f(x) = 12.5(1.6^x)
Step-by-step explanation:
An exponential model is generally of the form ...
f(x) = a·b^x
where 'a' is the initial value (for x=0), and 'b' is the growth factor, the multiplier when x increases by 1.
<h3>Growth factor</h3>
The ratio of the f(x) values for x=0 and x=1 is 20/12 ≈ 1.67. A number close to this will be the growth factor in the exponential function. There is only one answer choice showing a growth factor near 1.6. (Eliminates choices A, C, D.)
An exponential regression model can be produced by many graphing calculators and spreadsheets. The attachment shows a model that has the values matching choice B.
First, you need to determine the possible side lengths of your third side. Here, your third side can be your hypotenuse or another side length. If it is your hypotenuse, it will be equal to sqrt(8^2+5^2)=sqrt(64+25)=sqrt(89). If it is your side length, it will be equal to sqrt(8^2-5^2)=sqrt(64-25)=sqrt(39). You can find the difference by subtracting these from each other in a calculator, making your difference equal to sqrt(89)-sqrt(39)≈3.2 inches.
