Using the line of best fit, the amount of texts a 15-year old would send in a day is of 67.69.

It gives the expected number of texts a person of an age a would send in a day, according to the following function:

t = -1.63a + 92.14.

For a person that is 15 years old, we have that a = 15, hence the expected number is given by:

t = -1.63 x 15 + 92.14 = 67.69 texts.

Answer:

A)25% B)Product B

Step-by-step explanation:

A) To find whether product A price is increasing or decreasing, we will find the difference in price between year 0 and 1 year after.

When x = 0,

f(0)  [tex]72(1.25)^{0}\\= 72*1\\= 72[/tex]

when x = 1,

f(1) = [tex]72(1.25)^{1}\\= 72*1.25\\= 90[/tex]

From here we can already see the price is increasing.

% increase = (Difference in price / Original Price) * 100

= [tex]\frac{90-72}{72} *100\\=\frac{18}{72} *100\\=0.25*100\\=25percent[/tex]

Therefore the price is increasing by 25% per year.

B) Same concept as Part A, we will find the price difference between year 1 and 2.

% increase = (Difference in price / Original Price) * 100

[tex]\frac{84.5-65}{65} * 100\\= \frac{19.5}{65} * 100\\= 0.3*100\\= 30 percent[/tex]

Therefore we can see here Product B has a higher increase than Product A.

Step-by-step explanation:

A

f(x) = 72 × 1.25 × x

so, the price is $90 after 1 year (72×1.25×1).

$180 after 2 years (72×1.25×2)

$270 after 3 years (72×1.25×3)

and so on.

or did you mean

f(x) = 72 × (1.25)^x

so, still, the price is $90 after 1 year (72×1.25^1).

$112.50 after 2 years (72×1.25^2).

$140.625 = $140.63 after 3 years (72×1.25^3)

that makes more sense. I will continue with that assumption.

so, the price is increasing, as every factor of the multiplication is positive and larger than 1. therefore, it only goes up.

and due to the formula, the price of every year is the price of the previous year multiplied by 1.25.

a multiplication by 1.25 is an increase of 25% (compared to a constant multiplication by 1).

so, the price increases every year by 25%.

B

year 1

price $65

year 2

price $84.50 difference $19.50

100% = 65

1% = 65/100 = 0.65

19.5/0.65 = 30% difference

year 3

price $109.85 difference $25.35

100% = 84.5

1% = 84.5/100 = 0.845

25.35/0.845 = 30% difference

year 4

price $142.81 difference $32.96

100% = 109.85

1% = 109.85/100 = 1.0985

32.96/1.0985 = 30% difference

so, product B has the greater percentage increase in the price (30% vs. 25%).

The amount that was invested 17 years ago is $2064.25.

The interest earned is  $7935.75.

The formula that would used to determine the amount that was invested 17 years ago is:

P = FV / (1 + r)^nm

Where:

10,000 / (1.0475)^(17 x 2) = $2064.25

Interest earned = 10,000 - 2064.25 = $7935.75

Answer:

Part A:

In order to find a coterminal angle, or angles of the given angle, simply add or subtract 360 degrees of the terminal angle as many times as possible.

Part B:Simply put, coterminal angles start at 0° and end at the same place, though in different directions and multiple times around (you're probably going to want to make that sound a little more formal). Since each time around is 360°, boom

Part C: 75° is in Quadrant II, right? If I go one more time around, 75 + 360 = 435°. I can also go "backward. Starting at 0 and going clockwise, I'm going 75 fewer degrees than all the way around, so 360-75 = 285° but since I'm going "backward" 75 - 360 = -285°. One more is on you.

Angle M = 52°, n = 15.2cm, p = 9.4cm

A triangle is a plane shape with three sides and three angles.

To define the triangle completely we have to know the measure of the three angles and three sides.

Analysis:

The triangle is a right-angled triangle

we need to find the remaining angle  M and two sides n and p

M + N + P = 180

M + 90 + 38 = 180

M = 180 - 128 = 52°

sin 52 = m/n

m = n sin 52

n = m/sin 52 where m = 12cm

n = 12/0.788 = 15.2cm

sin 38 = p/n

p = n sin 38

p = 15.2 x 0.615 = 9.4cm

In conclusion, solving the triangle means finding M, n and p which are 52°, 15.2cm and 9.4cm respectively.

The equation of the scenario is y = 8 + 0.25x and the domain is x ≥ 0 and the range is y ≥ 8

The given parameters are:

Let the total cost be y, and the number of people be x.

The equation would be:

y = Entrance + Rate * x

This gives

y = 8 + 0.25x

Hence, the equation of the scenario is y = 8 + 0.25x

Set x = 0 to 5, and calculate the function values

y = 8 + 0.25 * 0 = 8

y = 8 + 0.25 * 1 = 8.25

y = 8 + 0.25 * 2 = 8.50

y = 8 + 0.25 * 3 = 8.75

y = 8 + 0.25 * 4 = 9.00

y = 8 + 0.25 * 5 = 9.25

So, the table of values is:

x    y

A

Take the product of corresponding components, then take the total:

u • v = (9i - 6j) • (-3i - 2j) = 9 (-3) + (-6) (-2) = -15

u • w = (9i - 6j) • (19i + 15j) = 9 × 19 + (-6) 15 = 81

Alternatively, use the definition and algebraic properties of the dot product.

• For any vector x,

x • x = ||x||²

where ||x|| is the magnitude of x.

• i • i = j • j = k • k = 1

• i • j = j • k = k • i = 0

• For any scalar c and any two vectors x and y,

cx • y = x • cy = c (x • y)

• For any vectors x, y, and z,

(x + y) • z = z • (x + y) = x • z + y • z

Then the products you want are

u • v = (9i - 6j) • (-3i - 2j)

… = -27 (i • i) + 18 (j • i) - 18 (i • j) + 12 (j • j)

… = -27 + 12 = -15

u • w = (9i - 6j) • (19i + 15j)

… = 171 (i • i) - 114 (j • i) + 135 (i • j) - 90 (j • j)

… = 171 - 90 = 81
