-The equation is actually
5x^2 -2x+1=0;
-The discriminant is b^2 -4ac=4-4•5•1=4-20=-16
-this means that the equation has no real number solutions
Answer:
<em>c. 13.899.79</em>
Step-by-step explanation:
<u>Exponential function
</u>
Two variables y and x have an exponential relation if
where C and k are real numbers. Many natural phenomena are modeled by using exponentials, finance included, where the growing of the investments can be computed through the use of the exponential function
The situation described in the question is modeled as
being A is the total value of the investment, p is the initial value of the investment, and n is the number of years the money is invested. We know p=2,500 and n=18, so we compute A
Answer: c. 13.899.79
Answer: b: s=n x 23
Step-by-step explanation:
When looking at the coordinates on the graph, each point increases by 23. 23 is multiplied by the number day it is (n)
Answer:
95-27.50= 67.50 inches of ribbon
Answer:
B and C
Step-by-step explanation:
Slope: 4-(-1)/-3-(-1)
Slope: 5/-2
Slope:-5/2
Point Slope form: y+1=-5/2(x+1)
Point Slope form: y-4=-5/2(x+3)
Correct answers are B and C
