Answer:

Step-by-step explanation:

Determine the number of solutions for each of the equations below. Be sure to

justify your conclusions. *

(z – 8)2 = -1

A. one solution

B. infinitely many solutions

C.no solution

D. x = 9

Given the expression;

(z – 8)^2 = -1

we are to find the nature of the solution;

Take the square root of both sides

(z – 8)^2 = -1

√(z – 8)^2 = √-1

z- 8 = √-1

Note that √-1 will give a complex number i to have;

z = 8 ± i

This therefore shows that the equation has no real solution.

Answer:

If a turkey takes two hours and forty-five minutes to cook, and you place it in at 3:30. It will be done at 6:15

Answer:

It will be ready at 6:15

Step-by-step explanation:

So you've got 2:45 for it to cook and it's been placed at 3:30. You can put it simply like:

2:45+3:30=x

x would represent the unknown time, all you need to do is add.

It's 5:75, but an hour only goes to 60 minutes and you've gone to 75.

You have to subtract 60 from the minute marker and add an hour:

5:75

 -60

6:15

Answer:

B (2,0)

Step-by-step explanation:

The solution of the system is (2, 0).

Simultaneous equations are any one or more equations that can have the same number of unknowns and be solved concurrently. The system of equations is the simultaneous equation.

Given information:

The system of equations,

y = -2x + 4

y = x- 2.

To find the solution to the system of equations, find the intersection points of the equations.

As per the graph given in the attachment below.

So, the intersection point is (2, 0).

Therefore, the point is (2, 0).

Answer:

27

Step-by-step explanation:

Note that since VX and XZ are both line segments, <VWX and <XYZ both equal 180 (also known as a straight angle). Also, note that the sum of the angles in a triangle are 180 degrees. Now, let’s start.

Finding angles of the triangle:

<WYX = <XYZ - <WYZ = 180 - 4x

<XWY = <XWV - <VWY = 180 - 6x

Using the sum of angles in a triangle and substituting these values in:

180 = <X + <WYX + <XWY = 90 + (180 - 4x) + (180-6x) = 450 - 10x

270 = 10x

27 = x

We are done! I hope this helps! :)

Answer:

the answer is A,

P(x) = -0.4x³+100x²-900x+500

Step-by-step explanation:

monthly cost:

[tex]c(x) = 600x {}^{2} + 300x[/tex]

monthly revenue:

[tex]r(x) = - 0.4 {}^{3} + 700x {}^{2} - 600x + 500[/tex]

profit function:

[tex]p(x) = r(x) - c(x)[/tex]

[tex]p(x) = ( - 0.4x {}^{3} + 700 {x}^{2} - 600x + 500) - (600x {}^{2} + 300x)[/tex]

i) remove the first bracket

[tex]p(x) = - 0.4x {}^{3} + 700x {}^{2} - 600x + 500 - (600 {x}^{2} + 300x)[/tex]

ii) there is a negative sign, '-' in front of the second bracket. so, change the sign of each term of the expression inside the bracket

[tex]p(x) = - 0.4x {}^{3} + 700 {x}^{2} - 600x + 500 - 600x {}^{2} - 300x[/tex]

iii) collect like terms

[tex]p(x) = - 0.4x {}^{3} + 700 {x}^{2} - 600 {x}^{2} - 600x - 300x + 500[/tex]

iv) simply the like terms

[tex]p(x) = - 0. 4{x}^{3} + 100 {x}^{2} - 900x + 500 [/tex]

4 is correct

reason is because the number next to x is the constant number and the end number is where you started

Answer:

g(x) = (x-8)^2 - 5

Step-by-step explanation:

subtracting from x inside of the square translates the function to the right and adding to x inside of the square translates it to the left.

(x-8)^2 - 1  translates the function 8 units to the right

subtracting from the constant translates the function down and adding translates it up.

x^2 - 5 translates the function 4 units down

Therefore, (x-8)^2 - 5 translates the function 8 units to the right and 4 units down

Answer:

No, none of the number need to be 48 for the mean to be 48. To get a mean, you add up all the number and divide it by the amount of numbers.

Example:

the mean of 10, 79, 42, 88, 19, and 50 is 48, but the actual number 48 was not part of the set.

10 + 79 + 42 + 88 + 19 + 50 = 288

288 ÷ 6 = 48

Answer: ≈ 55.045

Step-by-step explanation:

The formula is A=Pe^rt

A = (?) projected population

P = 42.4 (current population)

r = 0.0145 (growth rate)

t = 18 (difference between years: 2022 - 2004)

A = 42.4e^0.0145(18)

A = 42.4e^0.261

A = 42.4(1.298227665)

A ≈ 55.045

Answer:

A

The x = ∛27 and x = 3 are solution to the equation x³=27 option (B) and option (C) are correct.

It is defined as the sum of two or more numbers. The original number is obtained by multiplying the cube root of a number three times; for example, the cube root of x is z.

We have equation:

x³ = 27

Taking cube root both side

∛x³ = ∛27

x = ∛27

x = 3

Thus, the x = ∛27 and x = 3 are solution to the equation x³=27 option (B) and option (C) are correct.
