hope that can help

Answer:

[tex]\boxed {\boxed {\sf m= - \frac{3}{5} }}[/tex]

Step-by-step explanation:

Slope can be found by dividing the change in y by the change in x.

[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]

where (x₁, y₁) and (x₂, y₂) are the points the line passes through.

The points we are given are:

[tex](-3,4 ) \ and \ (2,1)[/tex]

Therefore,

[tex]x_1=-3 \\y_1= 4 \\x_2= 2\\y_2=1[/tex]

Substitute the values into the formula.

[tex]m=\frac{1-4}{2--3}[/tex]

Solve the numerator.

[tex]m= \frac{-3}{2--3}[/tex]

Solve the denominator.

[tex]m= \frac{-3}{5}[/tex]

This fraction cannot be simplified further, so this is the slope.

The slope of the line is -3/5

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

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.

Answer:

e

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=2X2-5x+5

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.

Yellow y=1/5x + 0

Red undefined

Green y = -3/2x - 4

Blue Undefined

Step-by-step explanation:

If a Slope is Vertical, the slope is undefined. I used rise/run for the others.

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

Answer:

155.3"^3

Step-by-step explanation:

the volume of a cone: 1/3 [tex]\pi[/tex]r^2 h

the volume of a right circular cone will be

1/3 [tex]\pi[/tex](5.1)^2 * 11.4

310.60 for a full circular cone.

for a right circular cone, we use 90/180 of the volume.

= 155.3

The volume of the cone is 121.8 in³.

A cone is a 3-dimensional shape that consists of a flat circular base and a tip known as the vertex.

Volume of a cone = [tex]\frac{1}{3}[/tex]πr²h

Where:

π = pi = 22/7

r = radius

h = height

Volume =  [tex]\frac{1}{3}[/tex] x 22/7 x 5.1² x 11.4 = 121.8 in³

To round off to the nearest tenth, if the hundredth figure is greater or equal to 5, add to the tenth figure, if this is not the case, the tenth figure remains unchanged.

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

Answer:

The student played basketball for 40 minutes.

Step-by-step explanation:

Given that one week a student exercised for 2 hours at school and for 2/3 of an hour at home, it can be stated that the student exercised for 2 hours and 40 minutes (since 60 x 2/3 is equal to 40 ). Thus, in total the boy exercised for 160 minutes (2 x 60 + 40).

Now, since he spent 1/4 of that time playing basketball, the time spent doing this sport is determined through the following calculation:

160/4 = X

40 = X

Thus, the student played basketball for 40 minutes.
