A local shop prints photos. The function f(x) = −x2 + 20x − 75 models the profit from one customer, where x is the number of pho

AnnZ [28]

Answer:

x = 5, x = 15; The zeros represent the number of photos printed to produce a maximum profit.

Step-by-step explanation:

F(x) = −x²+ 20x − 75

Let's f(x)= 0

0= -x²+20x-75

0= x²-20x+75

0=x²-5x-15x+75

0= x(x-5)-15(x-5)

0= (x-5)(x-15)

The zeros are

X= 5 or x = 15

And the xeros represent a number of photos printed to produce maximum profit

A torch and a battery cost £2.50 altogether. The torch costs £2.00 more than the battery.

Genrish500 [490]

Answer:

$\frac{1}{10}$

Step-by-step explanation:

Let $t$ represent the cost of the torch and $b$ represent the cost of the battery.

The torch and a battery cost £2.50 altogether.

$\Rightarrow t+b=2.50$

The torch costs £2.00 more than the battery.

$\Rightarrow t=b+2.00$

We substitute the second equation into the first equation to get;

$\Rightarrow b+2.00+b=2.50$

$\Rightarrow 2b=2.50-2.00$

£2.50

$\Rightarrow 2b=0.50$

$\Rightarrow b=0.25$

The price of the battery is £0.25

We express this as a fraction of the total cost which is £2.50 to get;

$\frac{0.25}{2.5}=\frac{1}{10}$

Select the functions that have identical graphs.

shtirl [24]

Answer:

c. 1 and 3

Step-by-step explanation:

To quickly solve this problem, we can use a graphing tool or a calculator to plot each equation.

Please see the attached image below, to find more information about the graph s

The equations are:

1) y = sin (3x + π/6)

2) y = cos (3x - π/6)

3) y = cos (3x - π/3)

Looking at the graphs, we can see that the identical ones

are equations one and three

Correct option:

c. 1 and 3
