Zeros are (-5,0) and (1,0)
Hence
y=-x²-4x+5y=-[x²+4x-5]y=-[x²+5x-x-5]y=-[x(x+5)-1(x+5)y=-(x-1)(x+5)Yes this is the parabola given
Convert to Vertex form a(x-h)²+kSo
y=-[x²+4x-5]y=-[x²+2(2)(x)-5+9-9]y=-[x²+2(2x)+4-9]y=-[(x+2)²-9]y=-(x+2)²+9As for any real x the function will give a real value [square present] the domain is set of real numbers ≤-2
vertex is maximum
Highest value of y is 9
Hence.
range is ≤9Or in interval notation
range=(-oo,9]Answer:
The range of the function is all real numbers less than or equal to 9.
Step-by-step explanation:
Given:
[tex]f(x)=-x^2-4x+5[/tex]vertex = (-2, 9)x-intercepts = (-5, 0) and (1, 0)Domain: input values (x-values)
Range: output values (y-values)
The domain of the function is not restricted, so the domain is all real numbers.
The leading coefficient of the function is negative, therefore the parabola opens downwards. This means that the vertex is the maximum point.
Therefore, the range will be f(x) ≤ 9 → all real numbers less than or equal to 9.

Using mathematically precise language, explain in detail how you would multiply the complex number z1=r1 (cos theta1+isin theta 1) with the complex number z2=r2 (cos theta 2+isin theta 2)
Answers
Answer:
Multiply the moduli and add the arguments.Step-by-step explanation:First write out the two terms being multiplied: z1z2= [r1(cos(theta 1) + isin(theta 1))][r2(cos(theta 2)+ isin(theta 2))] z1z2= r1r2 (cos(theta 1) + isin(theta 1))(cos(theta 2)+ isin(theta 2)) z1z2= r1r2(cos(theta 1)cos(theta 2))+(icos(theta 1)sin(theta 2))+(icos(theta 2)sin(theta 1))+(i^2 sin(theta 1)sin(theta 2)) Next group and rewrite the like term with the sums and differences. Your answer is the multiplication of the moduli and the addition of the arguments: z1z2= r1r2[cos(theta 1 + theta 2) + i sin (theta 1 and theta 2)].
The product complex number is [tex]z_1z_2[/tex]= [tex]r_1r_2[/tex][cos (θ1+θ2) + i sin (θ1+θ2)].
What is Complex number?A real number and an imaginary number are effectively combined to create a complex number. The complex number is written as a+ib, where a and ib are real and imaginary numbers, respectively.
We have,
z1=r1 (cos θ1 +i sin θ1)
z2=r2 (cos θ2 +i sin θ2)
where r-radius/radii
and, m-modulus/moduli
Now, the product is
[tex]z_1z_2[/tex] = r1 (cos θ1 +i sin θ1) x r2 (cos θ2 +i sin θ2)
[tex]z_1z_2[/tex] = r1 r2(cos θ1 . cos θ2 +i cos θ1 sin θ2 + i sin θ1 cos θ2 + i² sin θ1 sin θ2)
[tex]z_1z_2[/tex] = r1 r2(cos θ1 . cos θ2 +i cos θ1 sin θ2 + i sin θ1 cos θ2 - sin θ1 sin θ2)
We know,
cos (a + b)= cos a cos b - sin a sin b
sin (a+b) = sin a cos b + cos a sin b
Thus, [tex]z_1z_2[/tex] = [tex]r_1r_2[/tex][cos (θ1+θ2) + i sin (θ1+θ2)].

Assume that Quick Release lets go of the ball 6 feet above the ground and the receiver
catches it 6 feet above the ground. The ball reaches a maximum height of 16 feet above
the ground halfway to the receiver. Write an algebraic rule that models the path of the
football. Show all your work and explain your reasoning.
Answers
The equation that models the path of the football released from the given position is h(t) = -10 + 25.37t - 16.1t².
Initial velocity of the ball
The initial velocity of the ball is determined by applying third kinematic equation as shown below;
Vf² = V₀² - 2gh
at maximum height, the final velocity, Vf = 0maximum height reached from the point of projection, = 16 ft - 6ft = 10 ft0 = V₀² - 2gh
V₀² = 2gh
V₀ = √(2gh)
V₀ = √(2 x 32.17 x 10)
V₀ = 25.37 ft/s
Equation of motion of the ballThe equation of the ball's motion can be modelled as follows;
h = V₀t - ¹/₂gt²
10 = 25.37t - ¹/₂(32.17)t²
10 = 25.37t - 16.1t²
h(t) = -10 + 25.37t - 16.1t²
Thus, the equation that models the path of the football at any given position is h(t) = -10 + 25.37t - 16.1t².

Since Seetha calculated the average number of visitors per week, the missing value is the average multiplied by 7, less the total of the non-missing values.
How is a missing value calculated from an average number?If a number is missing from an average number, we can find the missing number by following these steps:
Add the non-missing numbers.Multiply the mean or average by the total number of variables (e.g. number of days in a week).Subtract the value of the non-missing numbers from the sum in (2) above.Thus, since Seetha calculated the average number of visitors per week, the missing value is the average multiplied by 7, less the total of the non-missing values.

[tex]f(40)=-144[/tex]
Step-by-step explanation:
Given:
[tex]f(1)=12[/tex][tex]f(n)=f(n-1)-4[/tex]This is a recursive arithmetic sequence since each term is defined using the previous term.
To find the nth term, convert the recursive formula to an explicit formula.
Explicit form of an arithmetic sequence: [tex]a_n=a+(n-1)d[/tex]
where:
[tex]a_n[/tex] is the nth terma is the first termd is the common difference between termsWe have been given the first term: [tex]a=12[/tex]
To get any term from its previous term we subtract 4, so the common different (d) is -4.
Therefore, the formula for the nth term is:
[tex]\implies a_n=12+(n-1)(-4)[/tex]
[tex]\implies f(n)=16-4n[/tex]
To find [tex]f(40)[/tex] simply substitute n = 40 into the explicit formula:
