Write a function in terms of t that represents the situation.
An item costs $4.50, and its price increases by 3.5%
each year.

Answers

Answer:

4.5(1.035)^t

Step-by-step explanation:

An inrease of 3.5% means that each year's total is 103.5% of the year before, right?

Year 1 = 4.5(1.035) = 4.66

Year 2 = 4.66(1.035) = 4.82

etc.

So, year 2 is 4.5(1.035)(1.035) = 4.82

Multiplying something by itself can be written with an exponent instead, so 2 years is...

4.5(1.035)2

Since the number of years is the variable (let's call it t)...

A 150-gram bag of berries is a mixture of raspberries and blueberries. If 80% of the bag is raspberries, how many grams of blueberries are in a bag?

Answers

Answer:

30g

Step-by-step explanation:

Since the bag is a total of 150 grams...

100% = 150

1% = 150 ÷ 100 = 1.5

Find out 80% of the bag which is finding out how many raspberries there are in the bag.

80% = 1.5 x 80 = 120

The remaining in the bag out of the raspberries is the berries.

150 - 120 = 30 (berries)

What is the withdrawal of $150 at the end of each year for 14 years with an interest rate of 7 percent

Answers

Answer:

$10.5

Step-by-step explanation:

Given data

P=$150

T= 1year

R= 7%

The simple interest formula will give the accurate amount at the end of each year

A=P(1+rt)

A=150(1+0.07*1)

A=150*1.07

A=$160.5

The withdrawal = 160.5-150= $10.5

Hence the withdrawal will be $10.5

Now na Brainlest ❣️ ko maka answer ❣️

Answers

Answer:

Step-by-step explanation:

In this question we will solve the polynomials by adding or subtracting the similar terms.

1). (-3x² - 8x + 2) + (-5x² - 9x - 2)

= (-3x²- 5x²) - (8x + 9x) + (2 - 2)

= (-8x²) - 17x + 0

= -8x² - 17x

2). (-2x² + 7x - 1) - (8x² - 6x + 5)

= (-2x² - 8x²) + (7x + 6x) - (1 + 5)

= -10x² + 13x - 6

3). (5x²- 5xy - 10y²) + (5x²+ 5xy + 10y²)

= (5x² + 5x²) + (-5xy + 5xy) + (-10y² + 10y²)

= 10x²

4). (2 + 8x + 4x²) - (9 + 6x + 2x²)

= (2 - 9) + (8x - 6x) + (4x² - 2x²)

= -7 + 2x + 2x²

5). (4x³ + 5x²+ 3x) - (3x³ + 6x²- 1)

= (4x³ - 3x³) + (5x² - 6x²) + 3x + 1

= x³- x² + 3x + 1
