Ijust need guidance on how to answer these, math isn't my best subject (clearly). !
1. in the formula s=a1(1−r), what restrictions are placed on the variable r?
2. the formula a=12bh can also be expressed as a=bh2. do you agree?
3. if x and y are real numbers, and xy=0, then either x=0 or y=0. do you agree?
4. do the inequalities x< 4 and x2< 42 both have the same solution set? explain.
5. discuss the graph of xy=0
6. how many y-intercepts can a function have?
how many x-intercepts can a function have?
7. does the graph of every quadratic function of the form
f(x)=ax2+bx+c
have a y-intercept? if so, what are the coordinates of the y-intercept?
8. how are the domain and range of a one-to-one function, f, related to the domain and range of the inverse function of f?
9. discuss the properties of the graph of f(x)=bx when b> 1
10. for what values of x is lnx> logx?
11. the maximum value of f(x)=3sinx+4 is 7. thus f has an amplitude of 7.
12. is the dot product of two vectors a vector or a scalar? explain.
13. are there any even prime numbers? if so, name them.
14. is the proposed simplification shown below correct? if it is incorrect, show a correct simplification.
2×3^2 = 6^2 = 36
15.
archimedes determined that 223/71< π< 22/7. is it possible to find an exact representation for π of the form ab, where a and b are integers?
can π be written as a fraction?
16. the expressions −a^n and (−a)^n don't always represent the same number. discuss the situations in which the two expressions are equal and those in which they are not equal.

Suppose a man is heterozygous for heterochromia, an autosomal dominant disorder which causes two different‑colored eyes in an individual, produced 25‑offspring with his normal‑eyed wife. of their children, 15 were heterochromatic and 10 were‑normal. calculate the chi‑square value for this observation.
