1. you have the following equation of the parabola in vertex form:
where h is the x-coordinate of the vextex and k is the y-coordinate of the vextex.
2. you know that the vertex of this parabola is at (-2, 5), then, susbtitute this point into the equation. then, you obtain:
3. therefore, the answer is the option c.
3 dimes, 9 pennies, and 5 nickels
call the number of dimes d. then, we will have 3d pennies and d + 2 nickels. the value for each group is 10d, 3d, and 5d + 10. add these to get 18d + 10. this is equal to 64 cents, as stated in the question. so, setting these equal, we get that d = 3, and there are 3 dimes, 9 pennies, and 5 nickels.
the factor (x - 8) has 1 zero at x = 8
the factor (x + 3)² has a zero at x = - 3 of multiplicity 2
in total there are 3 zeros
34,258 and 47,163
the value of 4 in the...
