Remember, if the two graphs are symmetric with respect to the line y = x (mirror images over y = x ), then they are inverse functions. But, we need a way to check without the graphs, because we won't always know what the graphs look like! then f(x) and g(x) are inverse functions.
First find the slope, take derivative of both sides with respect to x.
2y dy/dx=3x^2+6x
solve for dy/dx
dy/dx=[3x^2+6x]/2y
plug in given vales of (1,2(
dy/dx=9/4
now you have everything you need to plug into point slope form
y-2=(9/4)(x-1)
answer is y=(9/4)x+(1/4)
Given:
Selling price of a machine = 7000/-
Gross loss = 20%.
To find:
The cost and gross loss.
Solution:
Let x be the cost of machine.
According to the question,
Divide both sides by 0.8.
So, the cost of the machine is 8750/-.
Now,
Therefore, the gross loss is 1750/-.
Answer:
1.- He received 388 dollars in exchange.
2.-(100 x 4) - (7.00 + 5.00)
= 400 - 12
= 488
3.- I buy 15 basketballs.
And I buy 6 soccer balls.
4.- (135 ÷ 9) (48 ÷ 8)
= 15, 6
Step-by-step explanation:
I hope I have helped you can you put that this is the smartest answer please?
A function assigns the values. The value of (p·p)(x) is x⁴ + 10x³ + 30x² + 25x.
<h3>What is a Function?</h3>
A function assigns the value of each element of one set to the other specific element of another set.
Given p(x)= x²+5x, therefore, the value of (p·p)(x) can be written as,
(p·p)(x) = p(p(x))
= (x²+5x)²+5(x²+5x)
= x⁴ + 25x² + 10x³ + 5x² + 25x
= x⁴ + 10x³ + 30x² + 25x
Hence, the value of (p·p)(x) is x⁴ + 10x³ + 30x² + 25x.
