4x + 8 = 10 ^ 1 the solution to the equation is x

Answer:

2500

Step-by-step explanation:

1×10^6/10=10%

=1×10^5 then divide by 10 will give 10

=1×10^4 divide by 4 to get 2.5 of the original 10%

=2.5×10^3

=2500

Step-by-step explanation:

the slope is a line is always the factor of x.

and it is the ratio (y coordinate difference / x coordinate difference) when going from one point to another.

y = 2x + 4

has the slope 2. which is 2/1. so, for every increase of x by 1 unit, y increases by 2 units.

and this line has a y-intercept of 4 (the y-value when x = 0).

remember, the slope-intercept form of a line is

y = ax + b

a is the slope, b is the y-intercept.

a perpendicular slope (90°) turns that ratio upside down and flips the sign (because if the original line was going up, the perpendicular line is going down and vice versa).

so, the slope of the perpendicular line is -1/2.

the y-intercept was already given to us, so the desired line equation is

y = -1/2 x + 3

or

y = -x/2 + 3

The rate of change of the cost in dollars with respect to the number of t-shirts printed is $0.75 per shirt.

An equation is an expression that shows the relationship between two or more numbers and variables.

A linear function is in the form:

y = mx + b

Where m is the rate of  change and b is the initial value of y.

Given that the cost f(x) in dollars for printing x, t-shirts is given by:

f(x) = 100 + 0.75(x - 50)

f(x) = 0.75x + 62.5

Comparing with linear function, the rate of change is 0.75

The rate of change of the cost in dollars with respect to the number of t-shirts printed is $0.75 per shirt.

Answer: a

Step-by-step explanation:

First term

[tex]\int \sqrt{10x-15} \mathrm{dx}[/tex]

We can use the substitution u=10x-15, meaning dx = 1/10 du.

[tex]=\frac{1}{10} \int \sqrt{u} \mathrm{du}\\\\=\frac{1}{15}u^{3/2}+C\\\\=\frac{1}{15}(10x-15)^{3/2}+C[/tex]

Second term

[tex]\int (10x-15)^{10} \mathrm{dx}[/tex]

We can use the substitution u=10x-15, meaning dx = 1/10 du.

[tex]=\frac{1}{10} \int u^{10} \mathrm{du}\\\\=\frac{1}{110} u^{11}+C\\ \\ =\frac{1}{110}(10x-15)^{11}+C[/tex]

Third term

[tex]\int \frac{1}{10x-15} \mathrm{dx}[/tex]

We can use the substitution u=10x-15, meaning dx = 1/10 du.

[tex]=\frac{1}{10} \int \frac{1}{u} \mathrm{du}\\\\=\frac{1}{10} \ln u+C\\\\=\frac{1}{10} \ln(10x-15)+C[/tex]

The one time fee is -$17 and the one-time fee cannot not be applicable to this scenario because it is negative

The given parameters are

Hourly rate, r = 20.00

Number of hours, h = 5.5

Total amount = 93.00

The total amount is calculated as:

Total amount = One time fee + Hourly rate * Number of hours

So, we have

93.00 = One time fee + 20.00 * 5.5

Evaluate the product

So, we have

93.00 = One time fee + 110

Subtract 110 from both sides

So, we have

One time fee = 93.00 - 110

Evaluate the difference

So, we have

One time fee = -17

Hence, the one time fee is -$17

Amount cannot be negative.

This means that the one-time fee cannot not be applicable to this scenario

Whenever you have a subtraction symbol next to a negative it automatically becomes positive.

Every point in the interval [2, 6] has an equal probability of occurring, 1/(6 - 2) = 1/4. So the PDF of X is

[tex]f_X(x) = \begin{cases} \frac14 & \text{if } 2 \le x \le 6 \\ 0 & \text{otherwise} \end{cases}[/tex]

Compute the CDF by integrating the PDF.

Let's consider an rational number for a moment. If I tell you that the fraction you used was 1/3 and gave you the first couple of numbers as in

1/3 = 0.33333.....

and asked you what the next number is, you should be able to tell me that the number to write down is 3.

Even something like 1/7 is well behaved.

1/7 = 0,142857142857142857 .... and tell you I want the next number, you should be able to see it as 1.

But an irrational number can't be handled that way. If I ask for the next digit after 5 when taking the square root of 2, you would have no idea what I was talking about without the help of a calculator.

Now if you multiply a rational by an irrational, you just get a bigger irrational, but it remains irrational.

Considering the definition of an equation and the way to solve it, the smallest four integers are 8, 10, 12, 14.

An equation is the equality existing between two algebraic expressions connected through the equals sign in which one or more unknown values appear.

The members of an equation are each of the expressions that appear on both sides of the equal sign.

The solution of a equation means determining the value that satisfies it. To solve an equation, keep in mind:

Being "x" n any integer, and knowing that:

So, the equation in this case is:

(2n + 2n +2 + 2n +4 + 2n + 6)÷ 4= 11

Solving:

(8n +12)÷ 4=11

8n +12= 11× 4

8n +12= 44

8n= 44 -12

8n= 32

n= 32 ÷ 8

n= 4

Then, the smallest four integers can be calculated as:

Finally, the smallest four integers are 8, 10, 12, 14.

Answer:

D

Step-by-step explanation:

an = 3/4 × an-1

let's see for n = 2

a2 = 3/4 × a1 = 3/4 × 4

n = 3

a3 = 3/4 × a2 = 3/4 × 3/4 × a1 = 3/4 × 3/4 × 4 = 9/16 × 4

so, we see, we multiply 3/4 one time less than n by itself and then by 4.

that makes D the correct answer.

the multiplication by (n - 1) in answer C would add 3/4 n-1 times instead of multiplying it n-1 times.

to apply n-1 multiplications we need to use n-1 as exponent.

The sum of the terms till infinity of the sequence 1, 1 / 4, 1 / 16, 1 / 64 will be 4 / 3.

We have the sequence:

1, 1 / 4, 1 / 16, 1 / 64. ​

Initial term = a

a = 1

Common ratio = d

d = 1 / 4

The formula for the sum of the terms to infinity is given by:

S_∞ = a / (1 – r)

S_∞ = ( 1 ) / (1 – 1 / 4)

S_∞ = 1 / ( 3 / 4 )

S_∞ = 4 / 3

The average yearly salary of the final year is 67000 in dollars.

An average is a single number selected to stand in for a collection of numbers; it is frequently the product of the sum of the numbers divided by the total number of the collection. For example, the average of the integers 2, 3, 4, 7, and 9 is 5.

Let x = the average salary of an individual with the bachelor's degree, in dollars.

Then the average salary of an individual with master's degree is (2x - 35000)in dollars.

According to the sum of these salaries is 118000 dollars:

x + (2x-35000) = 118000

by solving we get

x = 153000/3

x = 51000

Hence, The average salary of an individual with the bachelor's degree is 51000 in dollars.  

the average salary of an individual with the master's degree (2*51000 - 35000) = 67000 in dollars.

The gain on the first oven = 18000 x 20% = 18000 x 20/100
= 18000 x 0.2 = 3600. Since it is a gain, we have to add this number

So selling price = 18000 + 3600 = 21600

The loss on the second oven is also the same 18000 x 0.2 = 3600. This time, it being a loss, selling price = 18000-3600 Total= 14400

The total before sales price of both ovens C  = 18000 + 18000 = 36,000

Total sold price S = 14, 400 + 21,600 = 36000

So net gain/loss = S - C = 36000 - 36000 = 0
