Answer:
B y = x² +9
Step-by-step explanation:
A quadratic function must have the highest power of x being x^2 and must have an x^2 term
A y = X-9 - linear
B y = x² +9 quadratic
C y = x + 2x -9 - linear
Answer:
Step-by-step explanation:
mean diameter = 206
variance = 6.25
standard deviation = √ variance
σ = √ 6.25 = 2.5
sample size n = 90
z = deviation from mean / (σ / √n)
= 0.3 / (2.5/ √90)
= .3 / .2635
= 1.1385
P value from the table = (.87 - .5 ) x 2
= .37 x 2 .
or 74 % .
Answer:
pick number 3
Step-by-step explanation:
We can solve for the value of x by applying the principles of sine and cosines method and laws of the inversed sign.
Given:
sin64°=cosx
Perform sin64° which is equal to 0.8987940463
0.8987940473=cosx
perform inverse sign:
cos-0.8987940473=x
x=26°
Therefore, the value of x is 26°.
The answer should be B.
5(6.86x)
