Your store is 150 ft. X 70 ft. The security cameras you are planning to purchase each cover 400 square feet. You want to cover the whole store. How many cameras do you need?.
There should be 27 cameras.
What is area?The amount of space filled by a flat (2-D) surface or an object's form is known as its area. Draw a square on a sheet of paper with a pencil. A 2-D figure, that is. The term "Area" refers to the area that a form occupies on paper. Now picture that your square is composed of smaller unit squares.
It is 150 feet by 70 feet.
The size of the store will be 150 x 70 feet, or 10,500 square feet. The security cameras now each have 400 square feet.
The area of the shop / each camera's area will determine how many cameras are needed, which is 10500/400.
which is 27
27 cameras are therefore required.

Let g(x)=x²-5 and h(x) = 3x + 2. Find (hog)(x)
The value of the composite function is (hog)(x) = 3x²- 13.
What is a composition function?
Function composition is an operation used in mathematics that takes two functions, f, and g, and creates a function, h = gof, such that h(x) = g. The function g is applied in this operation on the outcome of applying the function f to x.
The functions are g(x)=x²-5 and h(x) = 3x + 2
The composition function (hog)(x) can be written as (hog)(x) =h(g(x))
Putting g(x)=x²-5 in (hog)(x) =h(g(x)):
(hog)(x) =h(x²-5)
Now putting x= (x²-5) in h(x) = 3x + 2:
h(x²-5) = 3(x² - 5) + 2
h(x²-5) = 3x² - 15 + 2
h(x²-5) = 3x² - 13
Therefore (hog)(x) = 3x² - 13.

Which recursive sequence would produce the sequence
10,35,135,...?
Answer:
10, 35, 135, 410, 1235, ...
Step-by-step explanation:
a(1) = 10
a(n) = 3 * a(n-1) + 5
This recursive sequence starts with the initial value of a(1) = 10, and each subsequent term is calculated by applying the formula a(n) = 3 * a(n-1) + 5. The resulting sequence would be:
a(1) = 10
a(2) = 3 * a(1) + 5 = 3 * 10 + 5 = 35
a(3) = 3 * a(2) + 5 = 3 * 35 + 5 = 135
a(4) = 3 * a(3) + 5 = 3 * 135 + 5 = 410
a(5) = 3 * a(4) + 5 = 3 * 410 + 5 = 1235
And so on. This recursive sequence generates the following sequence: 10, 35, 135, 410, 1235, ...

Which model represents a function?
Model III represents a function by vertical line test.
What is Vertical line test?
The vertical line test is a graphical method of determining whether a curve in the plane represents the graph of a function by visually examining the number of intersections of the curve with vertical lines.
The vertical line test concludes that a curve in the plane represents the graph of a function if and only if no vertical line intersects it more than once.
According to the given question:
Graph I has vertical line intersections more than one on many points of the curve. Therefore, Graph I does not represents a function.
Model II has two values for the domain point that is -5 has two images 2 and 10. Hence it does not represents a function.
Graph III has only one intersection by vertical lines on the curve. Therefore, Graph III represents a function.
Graph IV has two intersection points if a vertical line passes through the curve. Hence, Graph IV does not represents a function.

Solving the equation x²+2x+7 using the quadratic formula, the resultant answer is x = -1 ± 2.44949i.
What is the quadratic formula?Any quadratic problem can be solved using the quadratic formula.
The equation is first changed to have the form ax²+bx+c=0, where a, b, and c are coefficients.
After that, we enter these coefficients into the following formula:
(-b±√(b²-4ac))/(2a)
Quadratic equations can be solved using one of three main strategies: factoring, the quadratic formula, or completing the square.
So, solving x²+2x+7 using the quadratic formula as follows:
Quadratic formula: (-b±√(b²-4ac))/(2a)
Substitute values and caluclate:
x = (-b±√(b²-4ac))/(2a)
x = (-2±√(2²-4(1)(7))/(2*1)
x = (-2±√4-28)/(2)
x = (-2±√-24)/(2)
Complex roots:
x = (-2±2√6i)/(2)
x = -2/2 ± 2√6i/2
Simplifying fractions:
x = -1 ± √6i
So, we have:
x = -1 ± 2.44949i

The required value of x of a triangle is 27°.
What is a triangle?
A triangle is a polygon with three vertices and three sides. The angles of the triangle are formed by the connection of the three sides end to end at a point. The triangle's three angles add up to 180 degrees in total.
Given, angle measurements of 2x, 4x+6, and x-15
Based on the definition of a triangle, the sum of all angles will be 180 degrees.
So, 2x + 4x+6 + x-15 = 180°
or, 7x - 9 = 180°
or, 7x = 189°
or, x = 189/7 = 27°
