Answer:
y - 4 = -(x - h)^2
Step-by-step explanation:
We begin with the stock function y = x^2. Its graph is a parabola with vertex at (0, 0) and opening up. The more general vertex form of the graph is
y - k = a(x - h)^2, where the point (h, k) is the vertex and 'a' determines the direction of opening as well as by how much the parabola is stretched vertically.
In this problem the vertex is (6, 4); that is, the vertex is shifted to the right by 6 units and upward from there by 4 units. The coefficient 'a' is -1, indicating that the graph opens downward.
So we have the equation y - 4 = -(x - h)^2. Without more information we cannot tell whether the graph is stretched vertically or not.
A poker game requires players to draw a card and roll a die. The combination of card and die will determine if a player wins. There are:
13 different types of cards: Ace, 2,3,4,5,6,7,8,9,10, Jack, Queen, King
6 different numbers, one on each face of a die: 1,2,3,4,5,6
How many different combinations are there of one card and one die roll?
Answer:
78
Step-by-step explanation:
13*6=78

If log2 5 = a, log2 3 = b and log2 7 = c, determine an expression for log2 (25/21) in terms of a, b, and c
Answer:
[tex]2a - b -c[/tex]
Step-by-step explanation: We know that:
[tex]log_{2} 5 = a\\log_{2} 3 = b\\log_2 7 = c\\[/tex]
and we want:
[tex]log_2 \frac{25}{21}[/tex].
We can form the numerator using just the first fact (since 5^2 is 25) and the denominator using the latter two (since 3*7 = 21).
[tex]log_2 \frac{25}{21} = log_2 \frac{5^2}{3*7}.[/tex]
The logarithm of a division can be expanded by subtracting the numerator and denominator (while still keeping the log). The logarithm of a product can be expanded by adding the terms while keeping the log. If the logarithm is raised to a power, we can bring it down as a factor:
[tex]log_2 \frac{5^2}{3*7} = log_2(5)^2 - log_2 (3*7) = 2 log_2(5) - (log_2 3 + log_2 7)[/tex]
[tex]= 2 log_2(5) - log_2 3 - log_2 7[/tex] .
Substituting the variables:
[tex]2 log_2(5) - log_2 3 - log_2 7 = 2a - b - c[/tex]

Answer:
One of the angles in the triangle might be 50.
AND
The length of the third side must be 11cm or smaller.
Step-by-step explanation:
-The triangle might be an equilateral triangle (having all the same sides and angles). False, since the triangle sum theorem states that all angles inside of a triangle must add up to 180, so an equilateral triangle would need to have all three angles at 60 degrees.
-One of the angles in the triangle must be 120 (false; it can be anything above 90, which is not only 120)
-The length of the third side must be 11cm or smaller. (True, Triangle Inequality Theorem)
-One of the angles in the triangle might be 50 (possibly, so very much true)

Answer:
$551.25
Step-by-step explanation:
1. Encuentre el 25% de $735:
0.25 x 735 = 183.75
2. Reste este número del precio original, $735:
735 - 183.75 = 551.25
The lady paid $551.25 after the 25% discount on merchandise.
What is Equation Modelling?
Equation modelling is the process of writing a mathematical verbal expression in the form of a mathematical expression for correct analysis, observations and results of the given problem.
We have a 25% discount is advertised on all merchandise. A lady bought a merchandise for $735.
Assume that she paid $x after the 25% discount. Then, we can write -
[x] = 735 - 25% of 735
[x] = 735 - (25/100) x 735
[x] = 735 - (1/4) x 735
[x] = 735(1 - 1/4)
[x] = 735 x 3/4
[x] = 551.25
Therefore, the lady paid $551.25 after the 25% discount on merchandise.

Write a polynomial function f of least degree that has rational coefficients, a leading coefficient of 1, and the given zeros.
3,-2+2i
Thank you!
Answer:
[tex]f(x)=(x-3)(x^2+4x+8)[/tex]
Step-by-step explanation:
A polynomial function is given by the form:
[tex]f(x)=a(x-p)(x-q)...[/tex]
Where a is the leading coefficient, and p and q are the roots (more can be added if necessary).
Our zeros are 3 and (-2 + 2i).
And our leading coefficient a = 1.
Furthermore, by the Complex Root Theorem, if (-2 + 2i) is a zero, then (-2 - 2i) must also be a zero.
So, by substitution, we acquire:
[tex]f(x)=1(x-(3))(x-(-2+2i))(x-(-2-2i))[/tex]
Simplify:
[tex]f(x)=(x-3)(x+2-2i)(x+2+2i)[/tex]
Expand the second and third factors:
[tex]\begin{aligned} &=(x+2-2i)x+(x+2-2i)(2)+(x+2-2i)(2i)\\&= (x^2+2x-2ix)+(2x+4-4i)+(2ix+4i-4i^2)\\&=(x^2)+(2x+2x)+(-2ix+2ix)+(-4i+4i)+(4-4i^2)\\&=x^2+4x+(4+4)\\&=x^2+4x+8 \end{aligned}[/tex]
Therefore, our polynomial function of least degree and the given zeros will be:
[tex]f(x)=(x-3)(x^2+4x+8)[/tex]
F(x)=2x+1 then find f(k)
Answer:
f(k) = 2*k + 1
Step-by-step explanation:
The 'f' function takes the variable, doubles it, and then adds 1.
So f(k) = 2*k + 1
f(g) = 2*g + 1
f(m) = 2*m + 1, and so on
It doesn't really matter which variable you use, the function still does the same thing to it.

A city manager made a scatter plot of the number of retail stores in a certain city over the years. The scatter plot had a trend line with an equation of y = 11x + 12, where y is the total number of retail stores and x is the number of years since 1990. 12. When Darryl and his family moved o the city, there were 133 retail stores in the city. Use the equation to predict what year Darryl's family moved to the city.
Answer:
2001
Step-by-step explanation:
133 = 11x + 12
121 = 11x
x = 11
1990 + 11 years = 2001
