Solve inequality -8x+4≤36.

Answer: A

Step-by-step explanation:

Letting [tex]f(y)=x[/tex],

[tex]x=\sqrt{y}-5\\\\x+5=\sqrt{y}\\\\y=(x+5)^{2}[/tex]

Also, the domain of an inverse is the same as the range of the original function, so the range is [tex]x \geq 0[/tex]

Answer + Step-by-step explanation:

[tex]f(x) = 5|x-6|+2 = \begin{cases}5\left( x-6\right) +2&if\ x\geq 6\\ 5\left( 6-x\right) +2 &if\ x\leq 6\end{cases}[/tex]

[tex]\Longrightarrow f(x) = \begin{cases}5x-30+2&if\ x\geq 6\\ 30-5x +2 &if\ x\leq 6\end{cases}[/tex]

[tex]\Longrightarrow f(x) = \begin{cases}5x-28&if\ x\geq 6\\ -5x +32 &if\ x\leq 6\end{cases}[/tex]

case 1: x ≥ 6 → f(x) = 5x - 28

5(6) - 28 = 30 - 28 = 2

Then

the point A(6 ,2) lie on the graph (line) of f

5(7) - 28 = 35 - 28 = 7

Then

the point B(7 ,7) lie on the graph (line) of f

Graphing :

When x ≥ 6 ,the graph of f is the ray [AB) (just connect the points A and B)

case 2: x ≤ 6 → f(x) = -5x + 32

-5(6) +32 = -30 + 32 = 2

Then

the point A(6 ,2) lie on the graph (line) of f

-5(5) +32 = -25 + 32 = 7

Then

the point C(5 ,7) lie on the graph (line) of f

Graphing :

When x ≤ 6 ,the graph of f is the ray [AC) (just connect the points A and C)

H_TM is reduced to HALT_TM and as such, HALT_TM is undecidable.

A language is referred to as Decidable or Recursive if there is a Turing machine that accepts and halts on every input string w. This tells us that every decidable language is Turing-Acceptable.

Now, we are told that the halting language is reducible to some language B. This means that it is an undecidability via reduction.

Now, Using the idea that “ If A is undecidable and reducible to B, then B is undecidable.” Suppose R decides HALT_TM, we will construct S to decide ATM .

S = “On input (M, B)

This means that H_TM is reduced to HALT_TM and as such, HALT_TM is undecidable.

Step-by-step explanation:

So the general formula for compound interest is [tex]A = P(1+\frac{r}{n})^{nt}[/tex] where t is typically time in years, and n is how many times it's compounded per year. But in this case it's only compounded 1 time per year so the equation is just [tex]A = P(1+r)^t[/tex]. in this case P is the principal amount, r is the interest, and A is the final amount. So the 5% interest rate becomes 0.05 by dividing by 100 to convert it into decimal form and the principle amount of 11,000. This gives you the formula [tex]A = 11000(1.05)^t[/tex]. This is the answer to the first question where t is the time in years. When it says "Find interest earned" I'm a bit confused, is it giving you x amount of years where you have to calculate the interest earned or does it want a general equation? Because the general equation would be the final amount - the principle amount which calculates the difference. So the equation for interest earned would be [tex]11000(1.05)^t-11000[/tex]. To calculate the amount of money after 5 years you simply plug in 5 as t. this gives you the equation [tex]11000(1.05)^5 \approx 11000(1.276) \approx 14,039.10[/tex]

The first four terms in the sequence are 4, 9, 16 and 25.

Given that, the nth term of the sequence is 1 (n + 1)².

We need to find the first four terms in the sequence.

In mathematics, a sequence is an enumerated collection of objects in which repetitions are allowed and order matters.

To find the first four terms of the sequence, replace n=1, 2, 3 and 4.

Now, when n=1

1(1+1)²=1×4=4

When n=2

1(1+2)²=1×9=9

Step-by-step explanation:

By means of recurrence formulas and a given initial value, we find the following three results: f(5) = 19, f(125) = 469, f(3125) = 11719.

Sequences are sets of values defined by at least one condition. In this case, we have three conditions to generate the required values:

f(n) = f(n/5) + 3 · n

f(1) = 4

[tex]n \in \mathbb{N}[/tex]

Now we proceed to find the elements by recurrence:

f(5) = f(1) + 3 · 5

f(5) = 4 + 15

f(5) = 19

f(25) = f(5) + 3 · 25

f(25) = 19 + 75

f(25) = 94

f(125) = f(25) + 3 · 125

f(125) = 94 + 375

f(125) = 469

f(625) = f(125) + 3 · 625

f(625) = 469 + 3 · 625

f(625) = 469 + 1875

f(625) = 2344

f(3125) = f(625) + 3 · 3125

f(3125) = 2344 + 9375

f(3125) = 11719

By means of recurrence formulas and a given initial value, we find the following three results: f(5) = 19, f(125) = 469, f(3125) = 11719.

Step-by-step explanation:

so, if I understand this correctly, the original function (shown in the graph) is

f(x) = sqrt(x)

the following transformations were done going from f(x) to h(x) :

x -> x + 4 as variable term moved the whole curve 4 units to the left. because now a specific functional value is calculated for a smaller x (by 4 units) than for the original f(x). e. g. let's call g(x) = sqrt(x + 4). then g(-4) = f(0). as mentioned, everything moved over to the left by 4 units.

sqrt(x) -> 3×sqrt(x) increased the range of the function (the generated y values) by the factor 3. was the functional result for a x value = 1, then it is now 3 for the same x value.

sqrt(x) -> sqrt(x) - 1 moved the whole curve down by 1 unit.

in summary, the whole original curve was moved 4 units to the left, then stretched upwards by the factor 3, and then that result was moved down by 1 unit.

so, e.g.

h(-4) = 3×f(0) - 1 = -1 point (-4, -1) corresponds to old (0, 0)

h(-3) = 3×f(1) - 1 = 2 point (-3, 2) corresponds to old (1, 1)

h(0) = 3×f(4) - 1 = 5 point (0, 5) corresponds to old (4, 2)

Let the circular stones = x

Let the rectangular stones = y

Equations

x + y = 37                          Subtract x from both sides of this equation.

y = 37 - x                           Notice that x is on the right side of the equation

Solution

26x   +  34y = 1138                 Substitute for y

26x + 34(37 - x) = 1138           Remove the brackets

26x + 1258 -34x= 1138           Combine

-8x + 1258 = 1138                    Subtract 1258 from both sides

-8x +1258-1258 = 1138-1258  Combine.  

-8x = -120                                Divide both sides by -8

-8x/-8 = -120/-8

x = 15                                       Two minuses make a plus (last step)

x+ y = 37

15 + y = 37                               Subtract 15 from both sides

15-15 +y = 37-15                     Combine

y = 22

Answer

x = 15     Circular pizza dishes

y = 22   square pizza dishes

The consultant sold 15 circular pizza stones and 22 rectangular pizza stones.

Let's assume the number of circular pizza stones sold is "c" and the number of rectangular pizza stones sold is "r."

We are given two pieces of information:

1. The total number of stones sold: c + r = 37

2. The total amount earned from the sale of the stones: 26c + 34r = 1138

Now, we can use these two equations to solve for the values of "c" and "r."

First, let's use the first equation to express "c" in terms of "r":

c = 37 - r

Now, substitute this value of "c" into the second equation:

26c + 34r = 1138

26(37 - r) + 34r = 1138

962 - 26r + 34r = 1138

Combine the "r" terms:

8r = 1138 - 962

8r = 176

Now, divide by 8 to find the value of "r":

r = 176 / 8

r = 22

Now that we have the value of "r," we can find the value of "c" using the first equation:

c = 37 - r

c = 37 - 22

c = 15

So, the consultant sold 15 circular pizza stones and 22 rectangular pizza stones.
