Answer:

C = 50 + 30d

Step-by-step explanation:

For one day,

50 + 30

For two days

50 + 2(30)

For d days,

50 + d(30)

C = 50 + 30d

1. The population of a town was 5655 in 2010. The population grows at a rate of 1.4% annually.

DaniilM [7]

Answer:

Step-by-step explanation:

a) We would use the formula for exponential growth model which is expressed as

y = b(1 + r)^t

Where

y represents the population after t years.

t represents the number of years.

b represents the initial population.

r represents rate of growth.

From the information given,

b = 5655

r = 1.4% = 1.4/100 = 0.014

Therefore, the equation would be

y = 5655(1 + 0.014)^t

y = 5655(1.014)^t

b) in 2022, t = 2022 - 2010 = 12 years

y = 5655(1.014)^12

y = 6682

Help me with a. b. c. I need help

Answer:

a) Perimeter = 20.5 Inches

Area is 15 Sq Inches

b) Perimeter is 61.4 Cms

Area is 210 Sq cm

c) Perimeter is 22 yards

Area is 21 Sq Yards

Step-by-step explanation:

a) Perimeter = sum of all the sides

= 8+7.5+5

=20.5

Perimeter = 20.5 Inches

Area of Triangle = $\frac{1}{2} \times height \times Base$

Base = 7.5 In

Height = 4 In

$A = \frac{1}{2} \times 4 \times 7.5$

$A = 2 \times 7.5$

$A = 15$

Hence Area is 15 Sq Inches

b) Perimeter = Sum of all the sides

P=13+23+13.4+12

P=61.4

Perimeter is 61.4 Cms

Area of trapezium = $\frac{1}{2} \times height \times (sum \ of \ parallel \ sides)$

$A= \frac{1}{2} \times 12 \times (12+23)$

$A= 6 \times 25$

$A=210$

Area is 210 Sq cm

c) Perimeter = Sum of all the sides

P = 7+4+7+4 ( as Opposite sides are equal in a parallelogram

P = 22

Perimeter is 22 yards

Area of a parallelogram = $base \times height$

$A= 7 \times 3$

$A = 21$

Area is 21 Sq Yards

Please help!! Question is above in the image

Answer:

$503.85

Step-by-step explanation:

The amortization formula can help with this.

A = P(r/12)/(1 -(1 +r/12)^(-n))

where P is the loan value, A is the monthly payment, r is the annual interest rate, and n is the number of monthly payments.

We want to find P. All of the other values are given.

P = A(1 -(1 +r/12)^-n)/(r/12)

P = 32.48(1 -1.012667^-18)/(0.012667) = 31.48·16.0054

P ≈ 503.85

The equivalent cash price is about $503.85.
