Answer:

x = 1.9 (option b)

Step-by-step explanation:

As an important property of the main height to the hypotenuse in a right triangle, we have: x*11 = height^2 = 4.6^2

=> x = 4.6^2/11 =~1.9

=> Option b is correct

Hope this helps!

PLEASE HELP! WILL MARK BRAINLIEST!!

Answer:

The y-intercept is (0,1). The x values at the horiz. intercepts are:

{ (-3+√5)/2, (-3-√5)/2 }. Graph is that of a parabola that opens down.

Step-by-step explanation:

It'd be helpful to rewrite f(x) = 3-x2+3x-2 with the powers of x in descending order and using " ^ " to denote exponentiation:

f(x) = -x^2 + 3x -2 + 3, or

f(x) = -x^2 + 3x + 1

y-intercept: let x = 0. Then f(0) = 1. The y-intercept is (0,1)

x-intercepts: let y = f(x) = 0 = -x^2 + 3x + 1. Let's use the quadratic formula with a = -1, b = 3 and c = 1 to determine the roots of this polynomial. The discriminant, b^2-4ac, is 9-4(1)(1), or 5.

Thus, there are two real, unequal roots. They are:

-3 plus or minus √5

x = ---------------------------------

or { (-3+√5)/2, (-3-√5)/2 }

These are your two horizontal intercepts, where the function is zero.

Because the coefficient -1 of the x^2 term is negative, the parabola representing this function opens down.

3.) You deposited $5,000 in an account that pays 4% annual interest. Find the

Maurinko [17]

The balance after one year is $5200

Step-by-step explanation:

The formula to apply here is

$A=P(1+\frac{r}{n} )^{nt}$

where

A=Amount of money at the end of the period=?

P=the amount of money invested= $5000

r=rate of interest=4%=0.04

n=number of compounding per year=1

t=time in years=1

Applying the formula

$A=P(1+\frac{r}{n} )^{nt} \\\\\\A=5000(1+\frac{0.04}{1} )^{1} \\\\\\A=5000(1.04)\\\\A=5200$

A=$5200

For the function f(x)=(1/2)⋅6^x , identify the domain, range, y-intercept, and asymptote.

skelet666 [1.2K]

Answer:

Step-by-step explanation:

f(x) = (1/2) *6^x = 2^-1 * 2^x *3^x

y= 2^ (x-1) * 3^x

Domain represents all values that x can have and is all real numbers

Range all values that y can have and is y > 0 ( all real numbers that are positive)

The y-intercept is the point where the graph intersects the y-axis so x=0 there

y = 2^(0-1) *3^0 = 1/2 *1 = 1/2

the asymptote is at y= 0
