<h2>The cost is same for both the options if we purchase 27 photos</h2>

Step-by-step explanation:

Cost of a photo at a local store is $0.25 per photo. This cost can be modeled to be linear in number of photos as $C_{1}(x)=0.25x$ .

Cost of photos purchased online is $0.15 per photo. However there is a shipping cost of $2.70. This can also be modeled to be linear in number of photos as $C_{2}(x)=2.70+0.15x$ .

Let us assume both costs are the same if we purchase $n$ photos.

So, $C_{1}(n)=C_{2}(n)$

$0.25n=2.70+0.15n$

$0.10n=2.70$

$n=27$

∴ On purchasing 27 photos, cost for both the options is the same.

Answer:

The digital photos need to be printed for the cost to be the same for both options is 11 photos

Explanation:

As per the given question, the cost to print digital photos at a local store is 0.25$ per pic.The cost to print digital photos online was $0.15 per photo and $2.70 for shipping.

For 1 pic – 0.25

X pics - 2.85

Therefore,

X = $\frac{2.85 \times 1}{0.25}$ = 11.4

approximately 11 photos are needed to be printed for the cost to be the same for both the options.

Write the equation of the sphere in standard form. x^2 + y^2 + z^2 + 2x − 4y − 6z = 22

madam [21]

The equation $x^{2} +y^{2} +z^{2} +2x-4y-6z=22$ in standard form looks like $(x+1)^{2} +(y-2)^{2} +(z-3)^{2} =(6)^{2}$ .

Given equation of sphere be $x^{2} +y^{2} +z^{2} +2x-4y-6z=22$ .

We are required to express the given equation in the standard form of the equation of sphere.

Equation is basically relationship between two or more variables that are expressed in equal to form. Equation of two variables look like ax+by=c. It may be linear equation,quadratic equation, cubic equation or many more depending on the powers of variables. The standard form of the equation of sphere looks like $x^{2} +y^{2} +z^{2} =r^{2}$ .
