If function g has the factors (x - 7) and (x + 6), what are the zeros of function g?

vagabundo [1.1K]

The zeroes of the function will be equal to ( 7, -6 ).

<h3>What is a quadratic equation?</h3>

It is a polynomial with a degree of 2 or the maximum power of the variable is 2 in quadratic equations. It has two solutions as its maximum power is 2.

Given function:-

( x- 7 ) ( x+ 6 )

As we can see that the quadratic equation in the factorized form is ( x - 7 ) ( x+ 6 ) so we will equate each factor to zero.

( x- 7 ) = 0

x = 7

( x+ 6 ) = 0

x = -6

Therefore zeroes of the function will be equal to ( 7, -6 ).

An object is launched from a platform.

Bess [88]

Answer:

60 feet

Step-by-step explanation:

The height, h (in meters), of the object launched from a platform is represented by the equation

$h=h(x)=-5x^2+20x+60$

where x is the time (in seconds) passed after the launch.

The time of launch is $x=0$ (0 seconds passed after the launch)

Substitute $x=0$ to find the height:

$h=h(0)=-5\cdot 0^2+20\cdot 0+60=60\ feet$

If a number is doubled then which of

Tamiku [17]

Answer: Its cube is six times the

cube of the given number.

Step-by-step explanation:

Let's assume we have a number which is 2. The cube will be:

= 2³

= 2 × 2 × 2

= 8

Let's now assume, we double the number 2, we'll have 2 × 2 = 4. Therefore, the cube will be:

= 4³

= 4 × 4 × 4

= 64

Therefore, from the explanation above, 2 raise to power 6 is 64. This means, if a number is doubled, then its cube is six times the cube of the given number.
