137.5 is 125% of what number

1 answer:

3 0

Percent means parts out of 100
125%=125/100=1.25

'of' menas multily

'is' means equals

137.5 is 125% of what
137.5=1.25 times what
divide both sides by 1.25
108=what

the number is 108

What is the inverse of y=^x3

Rashid [163]

Answer:

Inverse of y=x^3 is f^-1(x) = ∛x

Step-by-step explanation:

We need to find the inverse of y=x^3

Step 1:

Interchange the variables:

x= y^3

Step 2: Now solve to find the value of y

=> y^3 = x

taking cube root on both sides of the equation

∛y^3 = ∛x

y=∛x

Step 3: Replace y with f^-1(x)

f^-1(x) = ∛x

So inverse of y=x^3 is f^-1(x) = ∛x

The polynomial p(x)=7^3-7x-6 has a known factor of (x+1) rewrite p(x) as a product of linear functions

san4es73 [151]

Answer:

$p(x)=(x+1)(x+2)(x-3)$ .

Step-by-step explanation:

Note: The given function is not correct.

Consider the given polynomial is

$p(x)=x^3-7x-6$

It is given that (x+1) is a factor of given function.

Using synthetic division, divide P(x) by (x+1) as shown below.

-1 | 1 0 -7 -6

| -1 1 6

--------------------------------------

1 -1 -6 0

--------------------------------------

Bottom line represents the coefficients of quotient except the last element because it is remainder. So, the given function can be written as

$p(x)=(x+1)(x^2-x-6)$

$p(x)=(x+1)(x^2-3x+2x-6)$

$p(x)=(x+1)(x(x-3)+2(x-3))$

$p(x)=(x+1)(x+2)(x-3)$

Therefore, the function as a product of linear functions is $p(x)=(x+1)(x+2)(x-3)$ .
