SOVA2 [1]

The simple interest Trey earns if he makes no additional deposit or withdrawal for a period of 6 years is 600

<h3>How to calculate simple interest?</h3>

  • Principal = 5,000

  • Rate = 2%

= 2/100

= 0.02

  • Time = 6 years

Simple interest = principal × rate × time

= 5000 × 0.02 × 6

= 600

What is the area of ​​a triangle ABC with AB=AC=5cm and BC=6cm?
Vika [28.1K]

Answer: 12 cm^2

Step-by-step explanation:

BC ==> Base of triangle

Divide the triangle in two parts:

BC/2=BC'

6/2=BC'

BC'=3

Distance formula: a^2+b^2=c^2

c^2-a^2=b^2

5^2-3^2=b^2

25-9=b^2

b^2=16

b=4 ==> height of triangle

Area of triangle=A. b=base. h=height

A=1/2 * b * h=

A=1/2 * 6 * 4

A=1/2 * 24

A=12 cm^2

Ray Of Light [21]

Answer:

Every day, 43% percent of people are added from the total number of people who receive the email

Step-by-step explanation:

we know that

The equation of a exponential growth function is given by

P(t)=a(1+r)^t

where

P(t) is the total number of people who receive the email

t is the time in days

a is the initial value

r is the rate of change

we have

P(t)=6(1.43)^t

so

a=6 ---> initial number of people who receive the email

(1+r)=1.43

solve for r

r=1.43-1\\r=0.43

Convert to percentage

0.43(100)=43\%

so

The daily percent change in the number of people who receive the email. every day is 43%

therefore

Every day, 43% percent of people are added from the total number of people who receive the email
