The ratio of dogs to cats in a veterinarian's office is 9:7. What is the ratio of the number of dogs
1 answer:
Answer:
The ratio of the number of dogs to the total number of dogs and cats in the veterinarian's office is 9:16.
Step-by-step explanation:
Ratio:
The ratio of a to b is given by:
The ratio of dogs to cats in a veterinarian's office is 9:7.
This means that for each 9 dogs, there are 7 cars.
What is the ratio of the number of dogs to the total number of dogs and cats in the veterinarian's office?
9 dogs
9 + 7 = 16 dogs and cats. So
The ratio of the number of dogs to the total number of dogs and cats in the veterinarian's office is 9:16.

Answer:
a.
Step-by-step explanation:
The given equation is;
To solve by the x-intercept method we need to graph the corresponding function using a graphing calculator or software.
The corresponding function is
The solution to is where the graph touches the x-axis.
We can see from the graph that; the x-intercepts are;
(-1,0),(3,0) and (6,0).
Therefore the real solutions are:
Consider the function 
, which has derivative 
.
The linear approximation of
for some value 
within a neighborhood of 
is given by
Let
. Then 
can be estimated to be
![\sqrt[3]{63.97}\approx4-\dfrac{0.03}{48}=3.999375](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7B63.97%7D%5Capprox4-%5Cdfrac%7B0.03%7D%7B48%7D%3D3.999375)
Since
for 
, it follows that must be strictly increasing over that part of its domain, which means the linear approximation lies strictly above the function . This means the estimated value is an overestimation.
Indeed, the actual value is closer to the number 3.999374902...
