Calculate the axis of symmetry in the equation Y = (x+1) (x-4)

algol [13]

Answer:

Every parabola has a turning point called the axis of symmetry,so for this question you just have to find the turning points

x turning point= -b/2a,and the y turning point is gotten by replacing the value of x in the equation

y=(x+1)(x-4)

=x^2-3x-4

a is 1,b is -3 and c is -4

x= -(-3)/2(1)

=1.5

and y=x^2-3x-4

=1.5^2-3(1.5)-4

= -6.25

therefore the axis of symmetry is (1.5,-6.25)

I hope this helps

Which of the following equations is not a linear equation? a. y = x + 6 b. y2 = x2 + 3 c. x = 5 d. 2x = 3y

vaieri [72.5K]

<h3>Of the four listed equations, B is the only equation that is not linear.</h3>

A linear equation is any equation that results in a straight line, as each value is a fixed number from the previous.

In a non-linear equation, a variable is being raised to a power, which results in a curved line.

1.06t can be written as (1.061/2)2t to give the approximate equivalent monthly interest rate based on an annual rate of 6%. Use

Tema [17]

Answer: $1.06^t$ .

Step-by-step explanation: We are given expression $1.06^t$ .

And $1.06^t$ expression is converted in $(1.06^{1/2})^{2t}$ .

Now, we need to transform the expression into a single exponent expression using the properties of exponents.

We know, according to the properties of exponents

$(a^m)^n = a^{m\times n}$

Applying same rule in given expression, we get

$(1.06^{1/2})^{2t} = (1.06)^{\frac{1}{2} \times 2t}$

On simplifying exponents, we would get t in exponent.

= $1.06^t$ .
