"Solving Equations by Completing the Square: m^2+2m-48=-6

Answers

Answer 1

Answer: $m^2+2m-48=-6 \n \n m^2+2m-48+6=0\n \nm^2+2m-42=0\n \na=1, \ b= 2, \ c= -42 \n \n\Delta = b^(2)-4ac = 2^(2)-4*1*(-42)= 4+168 =172 \n\n√(\Delta )=√(172) =√(4*43)=2√(43)\n \nx_(1)=(-b-√(\Delta ))/(2a) =(-2-2√(43))/(2)=(2(-1-√(43)))/(2)= -1-√(43) \n \nx_(2)=(-b+√(\Delta ))/(2a) = (-2+2√(43))/(2)=( 2(-1+√(43)))/(2)= -1+√(43)$

Answer 2

Answer: $m^2+2m-48=-6\n\nm^2+2m\cdot1+1^2-1^2=-6+48\n\n(m+1)^2-1=42\n\n(m+1)^2=42+1\n\n(m+1)^2=43\iff m+1=-√(43)\ \vee\ m+1=√(43)\n\nm=-1-√(43)\ \vee\ m=-1+√(43)$

Find the Horizontal Asymptote of the exponential function, and then identify the transformations.f(x) = -2^(2-5) + 3

Answers

Answer:jjjjjjjjjjjjjjhhhhhhheeeeeeeaaaaa

Step-by-step explanation:

Answer:

f(x)=23/8

Step-by-step explanation:

To find horizontal asymptotes: If the degree (the largest exponent) of the denominator is bigger than the degree of the numerator, the horizontal asymptote is the x-axis (y = 0). If the degree of the numerator is bigger than the denominator, there is no horizontal asymptote.

Susan wants to make pumpkin bread and coffee cakes for the school bake sale. She has 15 eggs and 16 cups of flour in her pantry. Her pumpkin bread recipe uses 2 eggs and 3 cups of flour. Her coffee cake recipe uses 3 eggs and 4 cups of flour. She plans to sell pumpkin bread loaves for $5 each and coffee cake loaves for $4 each. Susan wants to maximize the money raised at the bake sale. Let x represent the number of loaves of pumpkin bread and y represent the number of loaves of coffee cake Susan bakes. What is the objective function for the problem? A. P = 15x + 16yB. P = 5x + 7y
C. P = 5x + 4y
D. P = 4x + 5y

Answers

Answer:

Option C is correct that is P=5x+4y

Step-by-step explanation:

We have given She has 15 eggs and 16 cups of flour in her pantry. Her pumpkin bread recipe uses 2 eggs and 3 cups of flour. Her coffee cake recipe uses 3 eggs and 4 cups of flour

Let x represents number of loaves of pumpkin bread

And y represents the number of loaves of coffee cake Susan bakes

Since, She plans to sell pumpkin bread loaves for $5 each and coffee cake loaves for $4 each.

Hence, P=5x+4y

Therefore, option C is correct.

The answer is C because in the problem, it states that Susan is selling pumpkin bread for 5 dollars, in which would be 5x. It also stated that she is selling coffee cake for 4 dollars each, in which would be 4x. When you add 5x and 4x, you will get the objective function.

Goal # = 82

Since we know we can't get "2"
using a multiple of the number [10]
therefore we must check [8]

[8] * 4 = 32
72 - 32 = 40
40 / [10] = 4

[] = $ per job

With this information we could say that:
Destiny made $72 from 8 jobs, 4 being mowing, and another 4 were weeding. Mowing 4 lawns earned her $32 while weeding 4 gardens earned her $40
