Is this correct? Please tell me if its right or not its very overdue!! Also if it's wrong please tell me the answer/what to do! question:

When Jack turned 21, he decided to start investing $200 a month every year for nine years. At age 30, he decided to stop investing altogether.

Blake started a little later, investing $200 a month every month starting at age 30, all the way until the ripe old age of 67.

Assuming that they were both amazing at investing and made 11% interest per year, how much money will they both have at age 67?

my

200 x 12 = 2400 per year

Jack:

2400* (1.11/1) ^ (1*46) = 291788.56346755

Blake:

2400 * (1.11 * 1) ^ (1 * 37) = 114067.3775

In δabc shown below, ∠bac is congruent to ∠bca: triangle abc, where angles a and c are congruent given: base ∠bac and ∠acb are congruent. prove: δabc is an isosceles triangle. when completed (fill in the blanks), the following paragraph proves that line segment ab is congruent to line segment bc making δabc an isosceles triangle. (4 points) construct a perpendicular bisector from point b to line segment ac . label the point of intersection between this perpendicular bisector and line segment ac as point d: m∠bda and m∠bdc is 90° by the definition of a perpendicular bisector. ∠bda is congruent to ∠bdc by the definition of congruent angles. line segment ad is congruent to line segment dc by by the definition of a perpendicular bisector. δbad is congruent to δbcd by the line segment ab is congruent to line segment bc because consequently, δabc is isosceles by definition of an isosceles triangle. 1. corresponding parts of congruent triangles are congruent (cpctc) 2. the definition of a perpendicular bisector 1. the definition of a perpendicular bisector 2. the definition of congruent angles 1. the definition of congruent angles 2. the definition of a perpendicular bisector 1. angle-side-angle (asa) postulate 2. corresponding parts of congruent triangles are congruent (cpctc)
