The unit price per kg is $5, to find this divide the 9 kilograms into the price $45 the answer is what each kilogram is worth
Answer:
c = -4
Step-by-step explanation:
If f(x) = 2x^3 - x + c and f(2) = 10, plug in 2 for the x values in the function and make the function output 10.
10 = 2(2^3) - 2 + c Now, we only have to deal with one variable, that is c.
10 = 2(8) - 2 + c
10 = 16 - 2 + c
10 = 14 + c
-4 = c After simplifying, we get that c is -4.
To check this, plug in 2 for x, and -4 for c in the function. If the function produces 10 as the result, the halleluja!
f(2) = 2(2^3) - 2 - 4
f(2) = 2(8) - 2 - 4
f(2) = 16 - 2 - 4
f(2) = 10
When two variables are inversely proportional the relation between them can be written as:
Here, k is the constant of proportionality and is always equal to the product of the two variables. So using the given values of z and x, we can find k first.
The constant of proportionality for the given inverse proportion comes out to be 2. Using the value of k in the equation, we get:
We have to find the value of z when x=28. So replacing x by 28, we get:
Thus, rounding of to nearest thousand the value of z comes out to be 0.071 if x is equal to 28.
Translation doesn't change the lengths of the sides or
the size of the angles. So when a figure is just translated,
the original image and the translated image are congruent.
