Which inequality represents all values of x for which the product below is defined? square root 5x times square root x + 3

Answers

Answer 1

The values of x for which the product:

√(5x)*√(x + 3)

Is defined are:

x ≥ 0

For which values of x is the product not defined?

Here we want to see for which values of x is the following product not defined.

√(5x)*√(x + 3)

Ok, remember that the argument of the square root must be zero or larger, then we have two inequalities here:

5*x ≥ 0

x + 3≥ 0

We can simplify both of these inequalities to get:

x ≥0

x≥ -3

We take the first one, which is more restrictive, the values of x for which the product is defined are:

x ≥0

Full Question = What kind of line does the linear inequality y=3x+5 represent?

solve:16^x+64=5*4^x-1​

Answers

Y = [tex]4^{x}[/tex] + 64 = 5y - 1, x = (5y - 65)/16, and x = (20*[tex]4^{x}[/tex] - 260). Take the logarithm of both sides, apply the laws of logarithms, and solve for x.

What is logarithm?

A logarithm is a mathematical function for expressing the relationship between two integers. It is the exponent to which a base number must be increased in order to equal a particular number. The base-10 logarithm of 100, for example, is 2, because 10 to the power of 2 equals 100.

Let y = [tex]4^{x}[/tex]

[tex]16^{x}[/tex] + 64 = 5y - 1

[tex]16^{x}[/tex] = 5y - 65

Dividing both sides by 16

x = (5y - 65)/16

x = (5*[tex]4^{x}[/tex] - 65)/16

Substituting y = [tex]4^{x}[/tex]

x = (5*([tex]4^{x}[/tex]) - 65)/16

Simplifying,

x = (5*[tex]4^{x}[/tex] - 65)/16

x = (20*[tex]4^{x}[/tex] - 260)/16

Divide both sides by 20

x = ([tex]4^{x}[/tex] - 13)/2

Take the logarithm of both sides:

log(x) = log([tex]4^{x}[/tex] - 13)/2

Apply the laws of logarithms:

log(x) = x*log(4) - log(13)/2

Solve for x:

x = (log(13)/2)/log(4) - log(x)/log(4)

x = (log(13)/2 - log(x))/log(4)

a) The numeric value at x = 4 is given as follows: f(4) = 64.

b) The logarithmic expression is given as follows: x = log2(16).

How to find the numeric value of a function or of an expression?

To find the numeric value of a function or of an expression, we replace each instance of the variable in the function or in the expression by the value at which we want to find the numeric value.

The function for this problem is defined as follows:

f(x) = 4(2)^x.

At x = 4, the numeric value is found replacing the lone instance of x by 4, hence:

f(4) = 4(2)^4 = 64.

For the logarithmic expression, we obtain the inverse function, hence:

64 = 4(2)^x.

2^x = 16

x = log2(16).

Find The coordinate of the interection of the diagonal of a parallelogram with the vertical WXYZ

Answers

The coordinate of the intersection is (k, m*k + b).

A parallelogram is a four-sided shape with opposite sides that are parallel. The diagonal of a parallelogram cuts the shape into two congruent triangles. The coordinates of the intersection of the diagonal of a parallelogram with the vertical line of the parallelogram can be found by solving the equation of the line that forms the diagonal and the equation of the vertical line.

If the diagonal of the parallelogram is given by the equation y = mx + b, where m is the slope of the diagonal and b is the y-intercept, and the vertical line is given by the equation x = k, where k is the x-coordinate of the vertical line.

To find the x-coordinate of the intersection point, we can substitute x = k into the equation of the diagonal:

x = k

Then, we can substitute this value of x into the equation of the diagonal:

y = mx + b

This will give us the y-coordinate of the intersection point.

So, the coordinate of the intersection is (k, m*k + b)

Note: You need the equation of the diagonal and the equation of the vertical line to find the intersection point.

Therefore, The coordinate of the intersection is (k, m*k + b).

(Opening the brackets)

(3x + 24)/4  = ( x - 6)/ 2

By cross multiplication,

2(3x + 24) = 4( x - 6 )

What is the differentiation of log 7 x?.

Answers

The derivative of log₇(x) is 1/(xln(7))

To find the derivative of log₇(x), we can use the chain rule and the properties of logarithms.

The chain rule states that if we have a composite function, such as y = f(g(x)), then the derivative of y with respect to x is given by

dy/dx = dy/dg * dg/dx.

In this case, y = log_7(x) and g(x) = x, so

dy/dx = d/dx (log_7(x))

As by logarithmic property log₇x = ln(x)/ ln(7)

dy/dx = d/dx (ln(x)/ln(7))

To find the derivative of ln(x), we can use the property that the derivative of ln(x) is 1/x. This is because the natural logarithm function is the inverse of the exponential function eˣ, and the derivative of eˣ is eˣ. Therefore, the derivative of ln(x) is the reciprocal of x, or 1/x.

The differentiation of log₇(x) is given by:

d/dx (log₇(x)) = (1/x) * (d/dx (x)) * (1/ln(7))

= (1/x) * 1 * (1/ln(7))

= 1/(x ln(7))

Answer:

The required linear function for the temperature T, in degrees Fahrenheit, of the oven m minutes from the time it was turned on until it reaches the desired temperature is T = 54m + 80.

Step-by-step explanation:

Given that,

An oven is turned on and set to reach the desired temperature of 350 degrees Fahrenheit. The oven warms up at a constant rate. The oven’s temperature is 134 degrees Fahrenheit at 1 minute and it reaches its desired temperature at 5 minutes.

What are functions?

Functions is the relationship between sets of values. e g y=f(x), for every value of x there is its exists in set of y. x is the independent variable while Y is the dependent variable.

Here,

At time m = 1 min, temperature T = 134 °F

At time m = 5 min. temperature T = 450 °F

Slope of the equation M = 450 - 134 / 5 - 1

                                        = 216 / 4

                                        = 54

Linat relationship can be given as,

T - 134 = 54 (m - 1)

T = 54m -54 + 134

T = 54m + 80

Thus, the required linear function for the temperature T, in degrees Fahrenheit, of the oven m minutes from the time it was turned on until it reaches the desired temperature is T = 54m + 80.

How to solve systems of linear equation in two variables by substitution?.

Answers

Solving systems of linear equations in two variables by substitution involves isolating one of the variables and substituting its value into the other equation.

This can be done by adding or subtracting the same term from both sides of one equation and then using that result to substitute into the other equation.

For example, consider the system of equations below:

2x + 3y = 8

3x + 2y = 7

Start by solving for x in the first equation by subtracting 3y from both sides:

2x + 3y = 8

2x = 8 - 3y

x = (8 - 3y)/2

Now substitute this expression for x in the second equation:

3(8 - 3y)/2 + 2y = 7

24 - 9y + 2y = 7

11y = 17

y = 17/11

Finally, solve for x, add y = 17/11 to the first equation as follows:

2x + 3(17/11) = 8  

2x + 51/11 = 8  

2x = 8 - 51/11  

x = (8 - 51/11)/2  

x = 21/22

The solution is x=21/22 and y=17/11.

What are the coordinates of the vertex for f/x )= 3x 2 6x 3?.

Answers

The coordinates of the vertex for f(x) = 3x²+6x+3 are (-1, 0).

For any equation of the type y=ax²+bx+c, the vertex is given by (h, k)

Where, h = -b/2a and k = (4ac - b²)/4a.

Given, the equation is y = 3x²+ 6x+3

Here, a = 3, b = 6 and c = 3

So, h = -6/2(3)

h = -6/6

h = -1

4ac = 4(3)(3)

4ac = 36

So, k = [36 - (6)2]/4(3)

k = (36 - 36)/12
