Mathematics
1 answer:
Deffense [45]2 years ago
8 0

Step-by-step explanation:

=>  2 {x}^{2}  +  \frac{7}{2}x +  \frac{3}{4}  = 0

=> \frac{8 {x}^{2}  + 14x + 3}{4} = 0

=> 8 {x}^{2}  + 14x + 3 = 0

=> 8 {x}^{2}  + 12x + 2x + 3 = 0

=> 4x(2x + 3) + 1(2x + 3) = 0

= > (2x + 3)(4x + 1) = 0

=  > x =  -  \frac{3}{2} or \frac{ - 1}{4}

For this case we first define the variable:
 x = number of terms.
 The equation that models the problem is:
 f (x) = 3.4 - 0.6x
 We have then that the first four terms are:
 x = 1
 f (1) = 3.4 - 0.6 (1) = 3.4 - 0.6 = 2.8
 x = 2
 f (2) = 3.4 - 0.6 (2) = 3.4 - 1.2 = 2.2
 x = 3
 f (3) = 3.4 - 0.6 (3) = 3.4 - 1.8 = 1.6
 x = 4
 f (4) = 3.4 - 0.6 (4) = 3.4 - 2.4 = 1
 Answer:
 
The rule for the sequence is:
 
f (x) = 3.4 - 0.6x

A dealer offers a $35,000 car with a downpayment of $3,000 and 65 easy monthly payments of $539.99. How much monthly interest ra
m_a_m_a [10]

Answer:

9.68%

Step-by-step explanation:

cost of car = $35,000

down payment = $3,000

number of monthly instalments= $65

amount in every monthly instalment= $539.99

total monthly payment= 65×539.99= 35099.35

amount to be paid apart from downpayment= $35,000-3000= 32,000

therefore total interest paid in 65 months= 35099.35-3200= $3099.35

now, monthly interest rate r= \frac{3099.35}{32,000}\times100

⇒ r= 9.68%
