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)...

At a football game
number of men : number of women : number of children = 13: 5:7
There are 4152 more men than women.
Work out the number of children at the game.

Answers

1884 i think the answer is-

The ratio of men to women at the game is 13:5. The difference between the number of men and women is 4152. Subtract 5 from 13 to work out the difference between the ratio value of men and women. 13-5=8. Divide 4152 by 8 to work out how many people 1 in the ratio represents. Then times this value (which is 519) by 7 (the ratio value for children) to work out the total number of children at the game. 519×7= 3633.

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

1. A community swimming pool is 7 yards 4.79 feet wide. How wide is the pool in meters and centimeters?

Conversion ratios:

1 m = 1.09 yd
1 yd = 3 ft
1 ft = 0.3048 m
1 m = 100 cm

Answers

Answer:

7.860792 meters and 786.0792 centimeters

Hence, the width of the pool is 7 meters and 86 centimeteres.

What is length?

Length is defined as the measurement or extent of something from end to end. In other words, it is the larger of the two or the highest of three dimensions of geometrical shapes or objects.

How to solve?

we know, 1yd = 3ft

7yd = 21ft

total length = 21 + 4.79

= 25.79ft

we know, 1ft = 0.3048m

25.79ft = 7.86m

which means 7meters 86 centimeteres

No worries! To fill the table, we need to take the x values and insert them for the f(x) value.

The equation we're given is

f(x)=2x²-5

Starting with 0, we have

2(0)²-5

0²-5

0-5

-5

If we repeat for the rest of the values, we get the f(x) values listed above.

Answer: 0= -5 1=-3 2=3 3= 13

To answer this for every Number there is for x you have to plug it in

2(0)^2 -5
2(0)-5
0-5
=-5

2(1)^1-5
2(1x1)-5
2-5
=-3

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)

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
