Gigi makes a scale drawing of a patio the drawing, The two scales are
Scale 1 is defined as 35ft by 25ft Scale 2 is defined as 56 ft by 40 ftThis is further explained below.
What are dimensions?Generally, In mathematics, a dimension is a measurement that may be taken in one direction to determine the size or distance of an item, area, or space.
To put it another way, it is the process of determining the dimensions of anything by calculating its length, breadth, and height.
Actual ratio measurements with a scale of 1
For the Lenght
Length=7 cm
Length =7*5
Lenght=35 ft
Width=5 cm
Width=5*5
Width=25 ft
Therefore
The dimensions are 35 ft by 25 ft
Find the actual dimensions of a ratio with the scale 2
A scale of 2 is equal to
1 cm/8 ft
For Length=7 cm
L=7*8
L=56 ft
For Width=5 cm
W=5*8
W=40 ft

if f(x)=x^2, what is g(x)? the graph shows the points: (1, -1), (-1,3), (-3,-1)?
IMAGE OF QUESTION
ANSWER
[tex]g(x)=-(x+1)^2+3[/tex]EXPLANATION
We have that the function graphed g(x) is a transformation of:
[tex]f(x)=x^2[/tex]When the parent quadratic function f(x) is transformed, it takes the following form:
[tex]g(x)=a(x-h)^2+k[/tex]This form also represents the vertex form of a quadratic equation, where (h, k) is the vertex of the function.
This means that we can find the function by using the vertex of the function.
The vertex of a function is the maximum or minimum value of the function; from the given graph, it is a maximum value and it is located at:
[tex](h,k)=(-1,3)[/tex]Therefore, we can input this into the vertex form of the function:
[tex]\begin{gathered} g(x)=a(x-(-1))^2+3 \\ g(x)=a(x+1)^2+3 \end{gathered}[/tex]Now, we have to find the value of a. To do this, pick any coordinate point from the graph and input it into the function above.
Let us pick:
[tex](0,2)[/tex]Therefore, we have:
[tex]\begin{gathered} 2=a(0+1)^2+3 \\ 2=a\cdot1+3 \\ 2=a+3 \\ \Rightarrow a=2-3 \\ a=-1 \end{gathered}[/tex]Therefore, the function graphed above is:
[tex]g(x)=-(x+1)^2+3[/tex]A(2h, h), B(p, t), and C(2p, 3t) are three points on a straight line. B divides AC internally in the ratio 2 : 3. Express p in terms of t.
p expressed in terms of t is -2t.
What is the section formula?The formula used to calculate the coordinates of a point on a line segment that divides it into two segments is referred to as the section formula. Let's imagine that the line segment marked with the coordinates A (x₁,y₁) and B(x₂,y₂) has a point P(x,y) that splits it in the ratio m:n. We employ the section formula, which is mathematically defined to determine the coordinates of P.[tex]P(x,y) = (\frac{mx_{2} + nx_{1} }{m+n} ),(\frac{my_{2} + ny_{1}}{m+n} )[/tex]
Given points on the straight line are A(2h, h), B(p, t), and C(2p, 3t).
B divides AC internally in the ratio 2 : 3.
Using the section formula, we determine the coordinates of B
[tex]B(p,t) =(\frac{2*2p + 3*2h}{2+3} ),(\frac{2*3t+ 3h}{2+3} )[/tex]
[tex]B(p,t) =(\frac{4p + 6h}{5} ),(\frac{6t+ 3h}{5} )[/tex]
Equate the points,
[tex]p =\frac{4p+6h}{5}[/tex]
[tex]5p = 4p +6h[/tex]
[tex]p =6h[/tex]
[tex]t= (\frac{6t+ 3h}{5} )[/tex]
[tex]5t = 6t +3h[/tex]
[tex]t = -3h[/tex]
[tex]h =\frac{t}{-3}[/tex]
So, [tex]p =6h = \frac{6t}{-3} = -2t[/tex]

Is the relation in this graph a function?
Answer:
the first is a function and the parabola is not a function
Step-by-step explanation:
A simple way to know why is the vertical line test.
Draw a vertical line and see whether if there are more than one point in the vertical line. If there's more than one point in the line then it's not a function, but if only one point on the vertical line it IS a function.
In the first graph, you'll notice that any vertical line you'll draw won't pass through two points ever. On the other hand, second graph will have two points found in the vertical line drawn by you, for example: (-2, 3);(-2, -3)

Create a table of data for two different linear functions. The table should use the same values of x for both functions. Based on your table, will the graphs of these two functions intersect? Explain your answer
These two functions' graphs do indeed intersect:
Formula 1: F(X)=2X+5
The formula 2=H(X)=3X+2
INTERSECT=(3,11)
Describe function:a mathematical phrase, rule, or law that establishes the link between an independent variable and a dependent variable (the dependent variable).Everywhere in mathematics are functions, which are essential for building physical connections in the sciences.
According to the given data:The first step is to generate two linear functions. I created the linear functions f(x)=2x+5 and h(x)=3x+2 (without a quadratic term). Then
You substitute a number for the x:
F(X)=2X+5 in Table 1 (H(X)=3X+2) Table 2
X=1——->Y=2+5=7 X=1------> Y=3·1+2=5
X=2---->
Y=2·2+5=9 X=2-----> Y=3·2+2=8
X=3---->

a ball dropped vertically, falls d t seconds.
d is directly proportional to the sqaure of t.
the ball drop 80 meters in the 4 seconds
how far does the ball drop in the next 8 seconds
If the ball drops 80 meters in the 4 seconds, the time it takes the ball to drop in the next 8 seconds is; 720 meters
How to utilize constant of proportionality?
We are told that a ball dropped vertically falls a distance of d in t seconds and that d is directly proportional to the square of t. Thus;
D ∝ t²
Thus;
D = kt²
where d is the constant of proportionality.
We are given that D = 80 m when t = 4 seconds and as such we have;
80 = k*4²
k = 80/16
k = 5
Therefore, the equation of motion is;
D = 5t²
When t = 8 + 4 = 12 seconds, we have;
D = 5 * 12²
D = 5 * 144
D = 720 m
Therefore, the distance the ball drops in the next 8 seconds
= 720 - 80
= 640 m.

Answer:
Gross Income = $ 43400
Adjusted Gross Income=$40500

given that-
Income paid to man
Wages = $41,500

Find an nth-degree polynomial function with real coefficients satisfying the given conditions. If you are using a graphing utility, use it to graph the function and verify the real zeros and the given function value. N=3; -3 and 4+4i are the zeros; f(-1)=82
The polynomial function is f(x) = x³ - 5x² + 8x + 96.
We have to find a polynomial of degree 3.We are given that the polynomial has -3, 4-4i, and 4+4i as its roots.We are also given that f(-1) equals 82.If x = -3 is a root, then:(x+3) is a factor of the polynomial.If x = 4-4i is a root, then:(x-4+4i) is a factor of the polynomial.If x = 4+4i is a root, then:(x-4-4i) is a factor of the polynomial.All the three roots are of the same polynomial.So, the polynomial is the product of these factors.f(x) = k(x+3)(x-4+4i)(x-4-4i)f(x) = k(x+3)[(x-4)² - (4i)²]f(x) = k(x+3)[x² + 16 - 8x + 16]f(x) = k(x+3)[x² - 8x + 32]f(x) = k[x³ - 8x² + 32x + 3x² - 24x + 96]f(x) = k[x³ - 5x² + 8x + 96]To find "k", we know that f(-1) = 82.f(-1) = k[(-1)³ - 5(-1)² + 8(-1) + 96]82 = k[-1 - 5 - 8 + 96]82 = k*82k = 1Thus, the polynomial is f(x) = x³ - 5x² + 8x + 96.To learn more about polynomials, visit :
