What is the value of the expression
below when a
8, b = 16, and c = -4 ?

The solution for the quadratic equation, c(x) = [tex]2x^{2} -192x+54[/tex] is +48.

Bob must repair 48 watches to have the lowest cost.

The axis of symmetry formula uses the standard form of the quadratic equation as well as the vertex form.

We have, c(x) = [tex]2x^{2} -192x+54[/tex]

As we know the axis of symmetry, using the formula:

x = [tex]\frac{-b}{2a}[/tex]

In the above equation a = 2; b = -192

x = [tex]\frac{-(-192)}{2 * 2}[/tex]

x= [tex]\frac{192}{4}[/tex]

x = +48

Hence, the number of watches for lowest cost bob must sold is 48 watches.

Answer:

Logan: 9

Ethan: 14

Step-by-step explanation:

Let Ethan = e

Let Logan = l

1) We can set up two equations and solve them simultaneously.

e + l = 23

5 + l = e

1.1) To solve these equations, we can either use substitution or elimination.

5 + l + l= 23

2l = 23 - 5

2l = 18

l = 18/2

l = 9

2) Plug the result of l into one of the two equations above.

5 + 9 = e

14 = e

In terms of decimal places, 18.84 is bigger because of the hundredths place(4). In terms of whole numbers, 28.8 is bigger.

Answer: 28.8

Step-by-step explanation:

If you look at the first digit on the left in the number 28.8, which is 2, then you look at the first digit of 18.84, which is 1, you can see that 2 is larger than 1, so therefore 28.8 is larger.

======================================================

Explanation:

Through trial and error, we can set up these equations

This shows that choices A, C and D are eliminated. This is because 5, 10 and 32 all can work as either x or y in x^y = 1024, and that the other value is some other integer.

On the other hand, x = 16 doesn't work and neither does y = 16 if we wanted the other value to be an integer.

Solving x^16 = 1024 leads to approximately x = 1.5422 when we focus on the positive real number solution. This isn't an integer, so x^16 = 1024 doens't have any integer solutions.

Solving 16^y = 1024 leads to a similar situation as described in the previous paragraph. It doesn't have any integer solutions either (instead the value is y = 2.5)

So we have a few ways of arriving at why choice B is the final answer.

The value of n which makes the statement "13 less than the product of 4 and a number, n, is 5" true, is 4.5.

Algebraic expression are the expression which consist the variables, coefficients of variables and constants.

The algebraic expression are used represent the general problem in the mathematical way to solve them.

The statement given in the problem is "13 less than the product of 4 and a number, n, is 5".

Here, the 13 less than the product of n and 4 (n×4-13) is equal to the number 5. In the equation form,

[tex]4\times n-13=5[/tex]

Add number 13 both side and simplify it further,

[tex]4\times n-13+13=5+13\\4n=18\\n=\dfrac{18}{4}\\n=4.5[/tex]

Thus, the value of n which makes the statement "13 less than the product of 4 and a number, n, is 5" true, is 4.5.

The area of Mrs. Leger's garden with length of (3x + 10) in and width of (2x + 7) in is 6x² + 41x + 70 in²

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

The area of a rectangle = length * width, hence:

Area of rectangular garden = (2x + 7) * (3x + 10) = 6x² + 41x + 70
