Answer:

x = 1 or   x= -2

Step-by-step explanation:

You have a parabolic function  or you can say quadratic function.

f(x) = x^2 + x - 2 = 0

x^2  + x + (1/4) - (1/4) - 2 = 0

(x + 1/2)^2   - 9/4 = 0

x + 1/2 =  root(9/4)

x + 1/2 = 3/2

x = 1  or -2

I’m confused on this one

6\sqrt2

Why?

We have the isosceles right triangle. The length of legs are 6. Use the Pythagorean theorem:

h^2=6^2+6^2\\\\h^2=36+36\\\\h^2=36\cdot2\to h=\sqrt{36\cdot2}\\\\h=\sqrt{36}\cdot\sqrt2\\\\h=6\sqrt2

In general, the formula for calculating the hypotenuse in an isosceles right triangle is h=a\sqrt2

a - a leg, h - a hypotenuse

Find the value of x for the right triangle.
pychu [463]

Answer:

x = 3

Step-by-step explanation:

take 60 degree as reference angle and using cos rule

cos 60 = adjacent/hypotenuse

1/2 = x/6

do cross multiplication

2*x = 6*1

x = 6/2

x = 3

marin [14]

The given functions appear to be ...

f(x)=4x\\g(x)=2^x\\h(x)=x^2+12\\j(x)=x^3

Of these, the exponential function g(x) will eventually exceed all others. That is the price of product 2, so ...

... The price of Product 2 will eventually exceed all others.
