Approximately how much money would Manny have if he invested $1,200 at an interest rate
quester [9]

Answer:

$1,701.64

Step-by-step explanation:

(see attached for reference)

recall that for compound interest, the following formula applies:

A = P [1 + (r/n) ] ^ (nt), where

A = final amount (we are asked to find this)

P = Principal amount = $1,200

r = interest rate = 5% = 0.05

t = 7 years

n = 12

Substituting these into the equation,

A = 1200 [1 + (0.05/12) ] ^ [(12)(7)]

A =  $1,701.64

Figure RST on the graph is reflected over the y-axis creating figure R’S’T’. Figure R’S’T’ is translated down 2 units and left 1
Crazy boy [7]

Answer:

RST Is congruent to R’’S’’T’’

Angle R is congruent to angle R prime is congruent to angle R double-prime

TS Is congruent to T’S’ Is congruent to T’’S’’

Step-by-step explanation:

we know that

A reflection and a translation are rigid transformation that produce congruent figures

If two or more figures are congruent, then its corresponding sides and its corresponding angles are congruent

In this problem

Triangles RST, R'S'T and R''S''T'' are congruent

That means

Corresponding sides

RS≅R'S'≅R''S''

ST≅S'T'≅S''T''

RT≅R'T'≅R''T''

Corresponding angles

∠R≅∠R'≅∠R''

∠S≅∠S'≅∠S''

∠T≅∠T'≅∠T''

therefore

RST Is congruent to R’’S’’T’’

Angle R is congruent to angle R prime is congruent to angle R double-prime

TS Is congruent to T’S’ Is congruent to T’’S’’
