The value of b is 
Explanation:
The given quadratic equation is 
And has x - intercept 
To determine the value of b, let us substitute the coordinates
in the given quadratic equation 
Substituting the x - intercept in the equation
, we have,

Simplifying, we have,


Adding the constant terms, we get,

Subtracting both sides by 10, we have,

Dividing both sides by -2, we get,

Hence, the value of b is 
Answer:
2= 4 1/6
Step-by-step explanation:
draw the diagram and extend BC to D
draw AD
use the Pythagorean Theorem with triangle ADC
call AD "h"
call DC "x"
h2+x2=102
now use the Pythagorean Theorem with triangle ADB
AD=h, AB=16, DB=(x+9)
h^2+(x+9)^2=16^2
from the first equation get h^2=10^2-x^2
from the second equation get h^2=16^2-(x+9)^2
set the two right sides equal to each other because they both equal h2
10^2-x^2=16^2-(x+9)^2
100-x^2=256-x^2-18x-81
cancel -x2 from both sides
100=256-18x-81
100=175-18x
100-175=-18x
-75=-18x
18x=75
x=75/18
x=4.1666... inches or 4 1/6 inches for the length of DC
The formula for this problem is A=P(1+(r/n))^nt.
A is what you're trying to find. P=400 r=0.06 t=3 n=1, since it's compounded once per year.
Now plug in those values to get A=400(1+(0.06/1))^1*3
I get an answer of $476.41
Correct option is D. As used in lines 1-2, "not readily verifiable" most
nearly means not completely understood.
Choice D is the best answer. In lines 1-6, the narrator says that he feels a
“vast yearning” and that his emotions are “complicated.” He explains that he does “not understand quite what it is that the yearning desires.” In this context, his emotions are “not readily verifiable,” or not completely understood.
Choices A, B, and C are incorrect because in this context, “not readily verifiable” does not mean unable to be authenticated, likely to be contradicted, or without empirical support.
