Answer:

he will have $832.20 in his account if it is adding the rate if it is subtracting the rate then it is $627.80

Step-by-step explanation:

you first need to find out what is 2.8% of $730. this number ends up being $20.44 and you multiply it by 5 because the account exists for 5 years. then depending on if it is adding or subtracting to the account. if it is adding then it will be $832.20, and if it is subtracting it will be $627.80

P.S. This is all done by a kid in middle school.

Answer:

Domain: set of possible input values (x-values)

Range: set of output values (y-values)

The range for the function [tex]f(x)=-2|x-5|+8[/tex] is:

[tex]f(x)\leq 8[/tex]

(5, 8) is the vertex of the line

Because |x - 5| is absolute (so always positive) and it is multiplied by -2,

-2|x - 5| will always be negative unless x = 5 (when it will be zero).  Therefore, the max y-value is 8.

However, your question actually asked what the function is when x = -5:

[tex]f(-5)=-2|x-5|+8\\\\= -2|-5-5|+8\\\\= -12[/tex]

Answer:  15/13

Step-by-step explanation:

F(x) = 6x + 11   and  g(x) = x+6

f(g(x)) = 6(x+6) + 11 = 6x + 36 + 11 = 6x + 47

Answer:

total profit = $428,517,224  (nearest whole number)

Step-by-step explanation:

Use geometric sum formula:

[tex]S_n=\dfrac{a(1-r^n)}{1-r}[/tex]

where [tex]a[/tex] is the initial value and [tex]r[/tex] is the common ratio

We have been told that the initial value is 242500, so [tex]a=242500[/tex].

If the company's profit increases by 22% per year, this means each year's profit is 122% of the previous year's profit. 122% = 122/100 = 1.22

Therefore, [tex]r = 1.22[/tex]

We need to calculate the total profit earned over 30 years, so [tex]n = 30[/tex]

Inputting these values into the formula:

[tex]\implies S_{30}=\dfrac{242500(1-1.22^{30})}{1-1.22}=\$428,517,224 \ \textsf{(nearest whole number)}[/tex]

1i) 3m. 3 x m is the same as 3m

1ii) 2m + 15. 2 x m + 15 can be written as 2m + 15

Answer:

3m and 2m+15

Step-by-step explanation:

"three times m" = 3 multiplied by m = 3m

"15 more than twice the given number"

Twice the given number is 2m. 15 more than that is 2m+15.

The ratio than could represent the number of large containers of milk to small containers of milk in order from the grocery store is 4:7 or 4/7.

The ratio is the simplest form of a fraction involving two quantities determining each other. It is written as a:b, read as "a is to b", and functions as a/b.

In the question, we are informed that a grocery store orders 4 large containers of milk for every 7 small containers of milk.

We are asked to determine the ratio of the number of large containers of milk to small containers of milk.

We know that a ratio is a fractional value, and for the number of large containers of milk to small containers of milk, we can write the ratio as:

Ratio = the number of large containers:the number of small containers = 4:7 or 4/7

Answer: 122376

Step-by-step explanation:

Applying the Pythagorean theorem, the length of the ladder to the nearest foot is: 14 ft.

The Pythagorean theorem states that if c is the hypotenuse of a right triangle, and a and b are the legs of the right triangle, then, c = √(a² + b²).

Thus, the ladder leaning on a building will form a right triangle, such that:

Hypotenuse = the length of the ladder = c

a = 5 ft

b = 13.1 ft

Therefore:

c = √(5² + 13.1²)

c = 14 ft

Therefore, applying the Pythagorean theorem, the length of the ladder to the nearest foot is: 14 ft.

Answer:

a)

Step-by-step explanation:

The y-intercept is when x = 0.

[tex]a^0=1[/tex], therefore when x = 0, y = 10

So the y-intercept is (0, 10)

The curve approaches the x-axis in quadrant 2, increases, passes through (0, 10) to quadrant 1 (see attached graph)

[tex]\frac{dy}{dx}=x^{2}(y-1)\\\frac{1}{y-1} \text{ } dy=x^{2} \text{ } dx\\\int \frac{1}{y-1} \text{ } dy=\int x^{2} \text{ } dx\\\ln|y-1|=\frac{x^{3}}{3}+C\\[/tex]

From the initial condition,
