Which value for the variable w makes the value of this expression 10? 50/w

Answer:

x = -20

Step-by-step explanation:

Solve for x:

(3 x)/4 + 7 = -8

Put each term in (3 x)/4 + 7 over the common denominator 4: (3 x)/4 + 7 = (3 x)/4 + 28/4:

((3 x)/4 + 28/4) = -8

(3 x)/4 + 28/4 = (3 x + 28)/4:

(1/4 (3 x + 28)) = -8

Multiply both sides of (3 x + 28)/4 = -8 by 4:

(4 (3 x + 28))/4 = -8×4

(4 (3 x + 28))/4 = 4/4×(3 x + 28) = 3 x + 28:

(3 x + 28) = -8×4

4 (-8) = -32:

3 x + 28 = -32

Subtract 28 from both sides:

3 x + (28 - 28) = -28 - 32

28 - 28 = 0:

3 x = -28 - 32

-28 - 32 = -60:

3 x = -60

Divide both sides of 3 x = -60 by 3:

(3 x)/3 = (-60)/3

3/3 = 1:

x = (-60)/3

The gcd of -60 and 3 is 3, so (-60)/3 = (3 (-20))/(3×1) = 3/3×-20 = -20:

Answer: x = -20

According to given information,

when, x is not equal to -2, that means g(x) = 4 for all values of x except " - 2 "

Therefore,

[tex]\qquad \sf  \dashrightarrow \: g( - 5) = 4[/tex]

and

[tex]\qquad \sf  \dashrightarrow \: g(3) = 4[/tex]

And, when x = -2, it's value is 2, hence :

In the context of the issue, the letter D represents the meaning of the y-intercept.

The value of the investment at the outset is determined to be $600.

Based on the data, the growth of the savings plan over the course of one year, denoted by the variable x, may be modeled using the exponential function f(x) = 600 * (1.04)x.

In this instance, the significance of the y-intercept in relation to the situation at hand is that the beginning value of the investment is equal to $600.

In conclusion, the choice D is the one that should be made.

Answer:

(A)  The initial value of the investment is $400.

Step-by-step explanation:

Got it right on my quiz.

The closest y-intercept is in function 1 so in option (A), the Greatest y-intercept is +4 in function 3 so in option (C), Functions 1 and 2 will have a slope less than 3 option (A) and (B).

The graph is a geometrical representation of a function and can be plotted by taking x's and y's corresponding values within the interval.

For example plot of y = x³ ,y = sinx.

Given four functions,

The y-intercept is a point on the y-axis where the graph intersects therefore coordinate of x will be 0.

In function 1 ⇒ y-intercept = -1 in rest, all it is far from 1 therefore it is close to 0.

The y-intercept of function 3 is →

y = x + 4 ⇒ y = 0 + 4 = 4 which is greatest positive value among all.

The slope of any function associated with two points (x₁, y₁) and (x₂, y₂) is given by

Slope = (y₂ - y₁)/(x₂ - x₁)

The slope of function 1 has points (0,-1) and (1,-5)

(-5 + 1)/(1 - 0) = -4 < 3

The slope of function 2 →

(5 - 8)/(-1 + 2) = -3 < 3 rest all function have slope as > 3.

Hence "The closest y-intercept is in function 1, the Greatest y-intercept is +4 in function 3 , Functions 1 and 2 will have a slope less than 3".

The [tex]\lim_{x \to 1} 7x-3=7(1)-3=4[/tex] using the ε − δ definition of a limit.

The value that a function approaches when the input approaches a certain value is known as a limit. Calculus and mathematical analysis are not possible without limits, which are also required to determine continuity, derivatives, and integrals.

The limit of f(x) at x = c is L according to the epsilon-delta definition of limits if ε > 0 there's a δ > 0 such that if the distance of x from c is less than, then the distance of f(x) from L is less than ε. The idea that we can approach L as closely as we like is expressed in this way.

[tex]\lim_{x \to a}f(x)= L[/tex] if ∀ ε > 0, ∃ δ > 0

0 < | x − a| < δ

⇒ | f(x) − L | < ε

Now, consider the limit

[tex]\lim_{x \to 1} 7x-3=4[/tex]

Here, f(x) = 7x - 3, a = 1, L = 4

Proof:

∀ ε > 0, ∃ δ = ε > 0

0 < | x - 1 | <  δ

⇒ | 7x - 3 - 4 | = | x - 1 | <  δ = ε

Hence, [tex]\lim_{x \to 1} 7x-3=4[/tex]

The coordinates of point S are (12,₋9)

Given, coordinates of T are (0,5)

midpoint of ST is (6,₋2)

When it is necessary to determine the precise center point between two specified points, the midpoint formula is used. So you may use this method to determine the point that divides a line segment specified by two points in half.

coordinates of S are = ?

we know the midpoint formula is (x₊x₁)/2 , (y₊y₁)/2

The midpoint calculation is the same as averaging two numbers. As a result, by adding any two integers together and dividing by two, you may find the midpoint between them.

substitute the given values in the formula.

(6,₋2) =  (x₊0)/2 , (y₊5)/2

for the x value of S:

x/2 = 6

x = 12

for the y value of S:

y₊5/2 = ₋2

y ₊ 5 = ₋4

y = ₋4 ₋ 5

y = ₋9

Therefore the coordinates of S are (12,₋9)

Student t distribution

A measurement of a data set's deviation from the mean is referred to as "standard deviation". While a high standard deviation indicates that the data are more spread, a low standard deviation suggests that the data are clustered around the mean.

The average of a group of variables is referred to as the mean in mathematics and statistics. There are several methods for calculating the mean, including simple arithmetic means (adding the numbers together and dividing the result by the number of observations), geometric means, and harmonic means.

We have,

Claim : μ = 83

Sample data : s = 15.1, n = 24, and x = 103

The hypothesis test uses the student t distribution because we are evaluating the mean in this situation, the sample standard deviation of a normal distribution is estimated or supplied, and the population's standard deviation is unknown.

Amount of sludge dispose per minutes is 100 lb.

What is Rate of change?

A rate is anything that can be measured over time. Common rates include velocity (which is the rate of distance traveled), power (rate of work being done), etc. All these have one thing in common which is that they are all divided by the amount of time it took to obtain a certain measurement.

Here it is given that :

A pump can dispose of sludge at the rate of 6,000 lb/h, that is in one hour pump dispose 6000 lb of sludge.

it is known that 1 hour = 60 minutes

Therefore, to find the amount of sludge dispose by pump in ome minute we divide 6000 with 60 :

amount of sludge dispose in one hour = 6000 lb

amount of sludge dispose in 60 minutes = 6000 lb

amount of sludge dispose in 1 minutes = 6000 lb/60 = 100 lb

Therefore, amount of sludge dispose per minutes is 100 lb

The bis the set of possible input values, and the range is the set of all possible output values of the graph.

In the sets:

Union (∪) of two sets means all the elements in the two sets without repeating the same elements

Intersection (∩) of two sets means the common elements in the two sets

∵ Set L = {0 , 20 , 40 , 80 , 100}

∵ Set M = {5 , 10 , 15 , 20 , 25}

∵ Set N = {10 , 20 , 30 , 40 , 50}

We need to find L ∪ (M ∩ N)

At first find (M ∩ N)

M ∩ N means find the common elements of M and N

10 and 20 are common elements in M and N

M ∩ N = {10 , 20}

Now find the union of L and {10 , 20}

L ∪ {10 , 20} means all elements in L and {10 , 20} without repeating the same elements

L ∪ {10 , 20} = {0 , 10 , 20 , 40 , 80 , 100}
