Suppose the cost of college tuition is expected to increase 5% every year. How much will the tuition at a comunity college cost
evablogger [386]

Answer:

$7,596.43

Step-by-step explanation:

The cost of the college tuition is increasing 5% compounded annually for 5 years.

∴ A = P(1 + r%)ⁿ

where A = tuition fee after 5 years.

           P = current tuition

           r = rate of increase

            n = period

A =  $5,952(1 + 5%)⁵

     = $5,952(1 + 0.05)⁵

     =  $5,952 × 1.05⁵

     = $7,596.43

    =

Geometry... Please help and I'll mark brainliest. Triangle proofs &amp; reasons
aliya0001 [1]

Answer:

<em>We are given that,</em>

<em>Polygons ABC and DBC are triangles.</em>

<em>Also, ABC and DBC are </em><em>Right</em><em> Triangles as ∠ABC and ∠DBC are 90 respectively.</em>

<em>AB ↔ CD</em>

<em>Now,</em>

<em>From the </em><em>HL Congruency </em><em>we know that,</em>

<u><em>"Two </em></u><u><em>Right</em></u><u><em> triangles are congruent if the </em></u><u><em>Hypotenuses </em></u><u><em>and at least </em></u><u><em>One Side </em></u><u><em> of both the triangles correspond to each other.</em></u><em>"</em>

<em>Here,</em>

  • <em>Triangles ABC and DBC were given to be right triangles.</em>
  • <em>AB </em><em>and </em><em>CD</em><em> are the hypotenuses of </em><em>ΔABC</em><em> and </em><em>Δ DBC</em><em> respectively. (From the construction of the figure) and are given equal.</em>
  • The Side BC of both the triangles correspond as they share the side BC together.

Here, As the three conditions of being congruent through HL Congruency are satisfied, ΔABC &  Δ DBC are congruent through the HL Congruency Criterion.

<em>ΔABC</em><em> ≅ </em><em>Δ DBC </em><em>[Hence, Proved]</em>

A 0.5 kg block is moving at constant speed on a horizontal surface. the friction force acting on the block is 20N, calculate uk
AlexFokin [52]

The friction force is equal to the normal force by the object equal to the weight of the object multiplied by the coefficient of friction. In this case, we substitute to the equation
4.9 N * 9.8 m/s2 = 20 N * ukuk is equal then to  0.245.
