Answer:

Step-by-step explanation:

The secant- secant angle CAD is half the difference of the intercepted arcs, that is

[tex]\frac{1}{2}[/tex] ( CD - BE ) = 20 ( multiply both sides by 2 )

CD - BE = 40 , substitute values

3x + 10 - 2x - 8 = 40

x + 2 = 40 ( subtract 2 from both sides )

x = 38

Thus

arc CD = 3x + 10 = 3(38) + 10 = 114 + 10 = 124° → e

Answer:

y=6x-8

Step-by-step explanation:

10-4/3-2

m=6/1

y=mx+b

y=6x+b

4=6(2)+b

4=12+b

-8=b

y=6x-8

The expression 4x < 4 is true, when x is less than 1

The inequality expression is given as

4x < 4

Divide both sides of the inequality by 4

So, we have

4x/4 < 4/4

Evaluate the quotient

x < 1

This means that the expression 4x < 4 is true, when x is less than 1

a) to find thhe x- intercept we make y=0

x² +4x -5 = 0

(x+5)(x-1) =0

x+5=0 so x=- 5

x-1 =0 so x= 1

b)

y-intercept is at (0, -5)

c)

axis of symmetry is at

x=-b/2a =-4/2*1 = -2

x= -2

d)

vertex is at (-2, -9) because x coordinate is on the axis of symmetry at -2 and

y= x² +4x -5= (-2) ² +4(-2)  -5 = 4-8-5 = 4-13 = -9

Step-by-step explanation:

Answer:

First Case:

[tex]\displaystyle p=\frac{5}{2}\text{ and } d=-2[/tex]

Second Case:

[tex]\displaystyle p=-\frac{5}{4}\text{ and } d=\frac{7}{4}[/tex]

Step-by-step explanation:

We know that the first three terms of an arithmetic series are:

[tex]6p+2, 4p^2-10, \text{ and } 4p+3[/tex]

Since this is an arithmetic sequence, each subsequent term is d more than the previous term, where d is our common difference.

Therefore, we can write the second term as;

[tex]4p^2-10=(6p+2)+d[/tex]

And, likewise, for the third term:

[tex]4p+3=(6p+2)+2d[/tex]

Let's solve for d for each of the equations.

Subtracting in the first equation yields:

[tex]d=4p^2-6p-12[/tex]

And for the second equation:

[tex]2d=-2p+1[/tex]

To avoid fractions, let's multiply the first equation by 2. Hence:

[tex]2d=8p^2-12p-24[/tex]

Therefore:

[tex]8p^2-12p-24=-2p+1[/tex]

Simplifying yields:

[tex]8p^2-10p-25=0[/tex]

Solve for p. We can factor:

[tex]8p^2+10p-20p-25=0[/tex]

Factor:

[tex]2p(4p+5)-5(4p+5)=0[/tex]

Grouping:

[tex](2p-5)(4p+5)=0[/tex]

Zero Product Property:

[tex]\displaystyle p_1=\frac{5}{2} \text{ or } p_2=-\frac{5}{4}[/tex]

Then, we can use the second equation to solve for d. So:

[tex]2d_1=-2p_1+1[/tex]

Substituting:

[tex]\begin{aligned} 2d_1&=-2(\frac{5}{2})+1 \\ 2d_1&=-5+1 \\ 2d_1&=-4 \\ d_1&=-2\end{aligned}[/tex]

So, for the first case, p is 5/2 and d is -2.

Likewise, for the second case:

[tex]\begin{aligned} 2d_2&=-2(-\frac{5}{4})+1 \\ 2d_2&=\frac{5}{2}+1 \\ 2d_2&=\frac{7}{2} \\ d_2&=\frac{7}{4}\end{aligned}[/tex]

So, for the second case, p is -5/4, and d is 7/4.

By using the values, we can determine our series.

For Case 1, we will have:

17, 15, 13.

For Case 2, we will have:

-11/2, -15/4, -2.

The number of roses that will be less expensive to order from A is 33

In this question, Florist A charges $4.75 per blue rose plus $40 delivery charge and the Florist B charges 5.15 per red pose plus 25$ delivery charge.

If Florist B increases the cost per rose to $5.20, we need to find the number of roses for which it would be less expensive to order from Florist A or Florist B.

Let the total charge be y and the number of rose be x

Florist A : the equation for the total cost would be,

y = 40 + 4.75x                     ---------1

Florist B : the equation for the total cost would be,

y = 25 + 5.2x                       --------2

We solve above equations to find the value of x i .e., to solve for the number of roses.

Equating equation 1 and 2,

40 + 4.75x = 25 + 5.2x

40 - 25 = 5.2x - 4.75x

15 = 0.45x

x = 15/0.45

x = 33.33

x ≈ 33

Therefore, the number of roses that will be less expensive to order from A is 33

Step-by-step explanation:

A.  (N • p)(x) = -8x² + 320x

B.  (N • p - C)(x) = -8x² + 120x .

Function - a function is a relationship or expression involving one or more variables.  It has a set of input and outputs.  Each input has only one output.  The function is the description of how the inputs relate to the output.

given that -

N(x) = x

p(x) = 320 – 8x  for  0 ≤ x ≤ 10

C(x) = 200x

(N ∙ p)(x) =?

(N ∙ p – C)(x) =?

For the question A....

         (N ∙ p)(x) = N(p(x))

         N(p(x)) = N(320 – 8x)  

         N(p(x)) = x(320 – 8x)

       (N ∙ p)(x) =  320x - 8x²

For the question B....

      (N ∙ p – C)(x) = N.((p-c)(x))

      N.((p-c)(x)) = N.(p(x) - c(x))

      N.((p-c)(x)) = x.(320 – 8x) -(200x)

      N.((p-c)(x)) = 320x - 8x² - 200x

      N.((p-c)(x)) = -8x² - 120x

Thus , the function represent (N • p)(x) = -8x² + 320x and (N • p - C)(x) = -8x² + 120x . These are the relationship between N , P , C.

The additional money that Ed Moura should invest in certificates of deposit paying 4% so that the average return on the two investments is 5% is 219,000.

Step-by-step explanation:

It is given that Ed Moura has $73,000 invested in stocks earning an average return of 8%, and that he should put the remaining funds in certificates of deposit paying an average return of 4%, the average return on the two investments is 5%, than;

=> 0.08 (73,000) + 0.04b = 0.05 (b + 73,000)

=> 5840 + 0.04b = 0.05b + 3650

=> 0.01b = 2190

=> b = 219,000

=> $219,000

Therefore, the additional money that Ed Moura should invest in certificates of deposit paying 4% so that the average return on the two investments is 5% is $219,000.
