We have that an inverse variation in a function is given by:
We must find the value of the constant k.
To do this, we substitute the values of x1 = 12, y1 = 15.
We have then:
Clearing k we have:
Substituting the value of k we have that the inverse variation is:
For y2 = 3 we have:
Clearing x2 we have:
Answer:
I am pretty sure your correct answer is 3380.
Hi there!
When we have an equation standard form...
...the formula of the discriminant is
D = b^2 - 4ac
When
D > 0 we have two real solutions
D = 0 we have one real solutions
D < 0 we don't have real solutions
1.) Find the value of the discriminant and the the number of real solutions of
x^2-8x+7=0
Plug in the values from the equation into the formula of the discriminant
D > 0 and therefore we have two real solutions.
2.) Find the value of the discriminant and the number of real solutions of
2x^2+4x+2=0
Again, plug in the values from the equation into the formula of the discriminant.
D = 0 and therefore we have one real solution.
~ Hope this helps you.
Answer:
72.00$
Step-by-step explanation:
25% = .25
.25 × 96.00 = 24
96 - 24 = 72
Answer:
1,536 square centimeters
Step-by-step explanation:
The formula for the Lateral surface area of the pyramid =
1/2 × perimeter of the square base × slant height
Square base = 32cm
Slant height = 24cm
Perimeter of the square base = (4 × length of the square base side)
4 × 32cm = 128cm
Lateral Surface Area = 1/2 × 128cm × 24cm
= 1,536 square centimeters
