The penguin's depth after 4 minutes is d = 10.7 + 146m

A rate is a ratio that compares two different quantities which have different units. For example, if we say John types 50 words in a minute, then his rate of typing is 50 words per minute. The word "per" gives a clue that we are dealing with a rate. The word "per" can be further replaced by the symbol "/" in problems.

if the penguin moves with a speed of 146 meters per minute, then its distance after m minutes is  = 146 x m

Since it moved from an elevation 10.7 below the sea surface, its total distance(d) would be = 10.7 + 146m

substitute m = 4 minutes,

we have

d  = 10.7 + 146(4)

d = 594.7metres

In conclusion, the function rule is 10.7 + 146m and the distance d covered after 4 minutes is 594.7 meters

the vertex : the turn-around point, where the parabola curve changes its tendency : (-3, 0.5)

axis of symmetry : since the parabola opens downwards, the axis of symmetry (it is like a mirror for one half of the curve to the other half) is a vertical line going right through the vertex : x = -3

y-intercept is the y-value when x = 0 : (0, -4)

x-intercepts are the x-values when y = 0 :

(-4, 0) and (-2, 0)

max or min : there is only one identifiable extreme value, it is at the vertex, of course, and is clearly a maximum :

at x = -3 the max value of the function is 0.5

the optimal value is the y-coordinate of the vertex (the function value between the 2 x-intercepts) : 0.5

4

y = 0.5x + 6 is linear. why ? because the highest exponent of x is 1. that creates a proportional relationship between x and y meaning y only increases with x in a constant manner.

y = 2x² + 5 is quadratic. why ? because the highest exponent of x is 2. this squares things, in other words, it makes them quadratic.

the graph as third item in the list is neither. the functional value gets exponentially bigger, the closer x gets to 0.

this looks like y = -1/x = x^(-1)

the graph as forth item in the list is a parabola again, and as such it is quadratic.

Answer:

  2.  $19,547.04

  3.  $10,276.54

  4.  $16,758.38

Step-by-step explanation:

You have three problems in compound interest with different initial payments, interest rates, and compounding intervals. You want the relationship between the initial payment and the future value.

The multiplier of a single payment earning annual interest rate r compounded n times per year for t years is ...

  k = (1 +r/n)^(nt)

For this problem, r=0.09, n=1, t=9. The multiplier of the payment is ...

  k = (1 +0.09/1)^(1·9) = 1.09^9 = 2.17189328

Then the future value of $9000 will be ...

  FV = $9000 × 2.17189328 ≈ $19,547.04

For this problem, r=0.10, n=12, t=4. The multiplier of the payment is ...

  k = (1 +0.10/12)^(12·4) = 1.08333...^48 = 1.48935410

Then the future value of $6900 will be ...

  FV = $6900 × 1.48935410 ≈ $10,276.54

For this problem, r=0.13, n=12, t=13. The multiplier of the payment is ...

  k = (1 +0.13/12)^(12·13) = 1.0108333...^156 = 5.3704484

Then the payment that gives a future value of $90,000 will be ...

  P = $90,000/5.3704484 = $16,758.38

Additional comment

For the spreadsheet calculation, we used the "Goal Seek" capability to adjust the value of cell F4 to 90000 by changing the value in cell B4.

We could have calculated the multiplier as above, then used it different ways for the different problems. Instead, we used one FV( ) function for all of the problems.

The required area of the flour in the square yard is A =n[ L×W ] where L and W are the length and width of the tiles respectively.

Given that,
A rectangular floor is long and wide. Pablo wants to carpet the floor with carpet titles sold by the square yard.

Surface area is defined as the area of the surface that is uncovered.

here,
Let for a tile the length be L and the width be W,
Assume that the number of tiles required is N,
The area of the N tiles is equal to the area of the rectangular floor,
Area of the floor = N [area of the tile]
Area of the floor (A = N [L× W]

To have $600,000 for retirement in 35 years at 5% interest, one would need to deposit $528.13 in the account each month.

Periodic deposits are monthly cash inflows into a retirement account that accumulates interest by compounding.

To find periodic deposits, we can use an online finance calculator, defining the parameters as follows.

N (# of periods) = 420 months (35 years x 12)

I/Y (Interest per year) = 5%

PV (Present Value) = $0

FV (Future Value) = $600,000

Results:

Monthly Deposits (PMT) = $528.13

Sum of all periodic deposits = $221,814.60

Total Interest = $378,185.40

Thus, monthly deposits of $528.13 can accumulate to $600,000 in 35 years at 5% interest.

Answer: Look at the graph

Step-by-step explanation:

The composition f(x) - g(x) has its value to be 12x

The definitions of the functions are given as

f(x) = (x - 3)²

Also, we have the definition of another functions to be given as

g(x) = (x + 3)²

To find the composition f(x) - g(x), we make use of the following equation

f(x) - g(x) = f(x) - g(x)

So, we have the following equation

f(x) - g(x) = f(x) - g(x)

Substitute the known values in the above equation

So, we have the following equation

f(x) - g(x) = (x + 3)² - (x - 3)²

Apply the differece of two squares rules

So, we have

f(x) - g(x) = (x + 3 + x - 3)(x + 3 - x + 3)

So, we have

f(x) - g(x) = (2x)(6)

This gives

f(x) - g(x) = 12x

Hence, the value of the composition is f(x) - g(x) = 12x

Scale of the map is 1 cm corresponds to an actual distance of 1.5 km

Step-by-step explanation:

According to the question,

4.2 cm on the map corresponds to an actual distance of 6.3 km.

So,

[tex] \rm 1 \: cm \: will \: correspond \\ \rm to \: a \: distance= \dfrac{6.3}{4.2} \: km \\ \rm = 1.5 \: km[/tex]

Scale of the map is represented by 1 cm corresponds to an actual distance of 1.5 km

The scale factor states the scale or measurement by which a figure is bigger or smaller than the other figure. The size by which the figure would be reduced or enlarged is called its scale factor.

According to the question we are given that 4.2 cm on the map corresponds to an actual distance of 6.3 km.

Similarly on the map, 4.2 cm corresponds to an actual value of 6.2km distance, this means

Thus 6.2km is the same as (6.2×1000)m = 6200m

therefore, the scale of the map is

= 4.2/6200

= 1/1476.2

that is, 1cm : 1476.2 cm

= 1cm: 1.5km

Based on the calculations, this equation 4f + 2(12f − 4) = 3(2f − 4) − f + 3 has one solution, which is equal to -1/23.

In Mathematics, no solution is also referred to as zero solution, and an equation is said to have no solution when the left hand side and right hand side of the equation are not the same or equal.

This ultimately implies that, an equation would have no solution or zero solution when both sides of the equal sign are not the same and the variables cancel out.

From the information provided, we have the following equation:

4f + 2(12f − 4) = 3(2f − 4) − f + 3

Opening the bracket, we have:

4f + 24f - 8 = 6f - 12 - f + 3

28f - 8 = 5f - 9

By collecting like terms, we have the following:

28f - 5f = -9 + 8

23f = -1

Dividing both sides by 23, we have:

The required total cost of the 11 kg of potatoes and 1½ kg of carrots is $7.72.

Given that,
The cost of 5 kg of potatoes is £3.40 the cost of 2 kg of carrots is 32p working out the total cost of 11 kg of potatoes and 1½ kg of carrots.

The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.

Here,
Cost of potatoes per kg = 0.68
Cost of 11 kg of potatoes = 0.68×11 = $7.48
Cost of the carrots per kg = 0.16
Cost of 1.5 kg carrot = 0.24
Total cost of the 11 kg of potatoes and 1½ kg = 7.48 + 0.24= $7.72.

Factors of 12 are: 1, 2, 3, 4, 6, 12

Factors of 24 are: 1, 2, 3, 4, 6, 8, 12, 24

Step 2: Let us identify the common factors of 12 and 24.

Common factors are: 1, 2, 3, 4, 6, 12

Step 3: Keep dividing the numerator and denominator by the common factors.

(12 ÷ 2)/(24 ÷ 2) = 6/12

What is Equation of line?

The equation of line in point-slope form passing through the points

(x₁ , y₁) and (x₂, y₂) with slope m is defined as;

⇒ y - y₁ = m (x - x₁)

Where, m = (y₂ - y₁) / (x₂ - x₁)

Given that;

The domain and the range is shown in table.

Two points on the line are (2, 5) and (7, 20).

Now,

Since, The equation of line passes through the points (2, 5) and (7, 20).

So, We need to find the slope of the line.

Hence, Slope of the line is,

m = (y₂ - y₁) / (x₂ - x₁)

m = (20 - 5) / (7 - 2)

m = 15 / 5

m = 3

Thus, The equation of line with slope 3 is,

⇒ y - 5 = 3 (x - 2)

⇒ y - 5 = 3x - 6

⇒ y = 3x - 6 + 5

⇒ y = 3x - 1

Therefore, The function will be;
