Answer:

m = -1

Step-by-step explanation:

The slope of a line is calculated as ;

Given : (-2,3) and (2,-1)

m = Δy/Δx

m= -1-3 /2--2

m = -4 /4 = -1

The slope is -1

Sum and Product of zeroes of the quadratic polynomial 16s² - 16s + 4 respectively is:Sum and Product of zeroes of the quadratic

andrew-mc [135]

Answer:

The sum and product of zeroes are 1 and 1/4, respectively.

Step-by-step explanation:

To determine the zeroes of the quadratic polynomial, let equalize the polynomial to zero and solve in consequence:

$16\cdot s^{2}-16\cdot s + 4 = 0$

By the General Quadratic Formula:

$s_{1,2} = \frac{16\pm \sqrt{(-16)^{2}-4\cdot (16)\cdot (4)}}{2\cdot (16)}$

$s_{1,2} = \frac{1}{2}$

Which means that zeroes are $s_{1}=s_{2}=\frac{1}{2}$ .

The sum and product of zeroes are, respectively:

$s_{1}+s_{2} =\frac{1}{2}+\frac{1}{2}$

$s_{1}+s_{2} = 1$

$s_{1}\cdot s_{2} = \left(\frac{1}{2} \right)^{2}$

$s_{1}\cdot s_{2} = \frac{1}{4}$

The sum and product of zeroes are 1 and 1/4, respectively.

The frog population at a lake doubles every week. The population can be modeled by f(x) = 15(2)x and f(6) = 960. What does the 9

insens350 [35]

Answer:

a is the correct option.

Step-by-step explanation:

We have been given the population model is $f(x)=15(2)^x, f(6)=960$

Here x represents number of weeks and f(x) is population of frog after x weeks.

For x= 6, we have

$f(6)=15(2)^6\\\\f(6)=15\times 64\\f(6)=960$

It means that the population after 6 weeks is 960.

Hence, f(6)=960 represents the population after 6 weeks.

a is the correct option.

What function is the inverse of y=-3x+6/7

Kisachek [45]

Y = -3x + 6/7
switch the x and y, then solve for y:
$y = -3x + \frac{6}{7} \\ x = - 3y + \frac{6}{7} \\ 3y = - x + \frac{6}{7} \:$
$3y \div 3 = (- x + \frac{6}{7}) \div 3 \\ y = - x \div 3 \: + \frac{2}{7}$
y = -x/3 + 2/7
