Find the inverse of f(x) = x^2 - 7
blondinia [14]

Answer:

y =  ±  sqrt(x+7)

Step-by-step explanation:

y = x^2 -7        solve for 'x'     .... add 7 to both sides

y+7  = x^2         sqrt both sides

+- sqrt(y+7)  = x        switch 'x' and 'y'

y = +- sqrt(x+7)

Solve for n 50 points <br><br> a=p(1+r/n)^rn
Andreyy89

Answer:

n = \frac{r}{\sqrt[nt]{\frac{a}{p}} -1 }

Step-by-step explanation:

a=p(1+\frac{r}{n} )^{nt}

\frac{a}{p} =(1+\frac{r}{n} )^{nt}

\sqrt[nt]{\frac{a}{p}}  =(1+\frac{r}{n} )

\sqrt[nt]{\frac{a}{p}} -1 =(\frac{r}{n} )

n = \frac{r}{\sqrt[nt]{\frac{a}{p}} -1 }

[ Do not confuse, as there are 2 n's, one in subject and another as power. We can never make the power or in a root, the subject. In order to solve for n, we have to make the character "n", the subject. ]

The base of the isosceles triangle is five times the height<br><br> Find the exact value of cot ø
Vika [28.1K]

Answer:

The exact value of cot(∅) is 2.5

Step-by-step explanation:

The picture of the question in the attached figure

we know that

An isosceles triangle has two equal sides and two equal interior angles

In his problem

AB=BC

m\angle BAC=m\angle ACB=\phi^o

In the right triangle ABD

cot(\phi)=\frac{AD}{BD} ---> adjacent side angle ∅ divided by the opposite side angle ∅

we have

The base of the isosceles triangle is five times the height

so

b=5h

AD=\frac{b}{2}=\frac{5h}{2}\ units

BD=h\ units

substitute

cot(\phi)=\frac{(5h/2)}{h}=2.5
