Answer:
The least number of meals Amelia needs to cater in order to begin making profit = 38 meals.
Step-by-step explanation:
Given - Amelia runs a catering business. Based on her records, her weekly
profit can be modeled by P= -2x² + 152x - 150, where x is the
number of meals she caters and P is her profit. When P is negative,
Amelia losses money.
To find - What is the least number of meals Amelia needs to cater in order
to begin making profit.
Proof -
As given, P = -2x² + 152x - 150
Now,
Above the break-even point, she only get profit
The break -even point is a point where there is no profit, and no loss.
Now,
For break-even point,
[tex]\frac{dP}{dx} = 0[/tex]
⇒[tex]\frac{d}{dx}( -2x^{2} + 152x - 150) = 0[/tex]
⇒-4x + 152 = 0
⇒- 4x = - 152
⇒4x = 152
⇒x = [tex]\frac{152}{4}[/tex] = 38
∴ we get
If Amelia caters at least 38 meals , then she makes Profit.

Step-by-step explanation:
They are asking if their is a relationship between the x and y value
for the left one, when the value of y is shown to be the x value divided by 3 as
11/3 =11 over 3, 12/3 = 4, 13/3 = 13 over 3
But the right answer does not seem to have any correlation/relationship between its x and y values

Fine the area of the trapezoid. Right answer gets brainliest!!
Step-by-step explanation:
use the formula to be able to find the area of the trapezoid
a = (a+b)÷2 × h
place the numbers into the formula
a = (30+17)÷2 × 22
solve
a = (47)÷2 × 22
a = 23.5 × 22
a = 517 m²

Barky's animal shelter has a total of 15
Chihuahuas and Yorkies. There are four
times as many Chihuahuas as Yorkies.
Using c for Chihuahuas and y for Yorkies,
determine which equation may be
used to represent this situation.
c=4+y
y=4+c
y=4c
c=4y
Answer:
c = 4y
Step-by-step explanation:
Are there more, Chihuahuas or Yorkies?
Does the word 'times' mean add, subtract, multiply or divide?
The way I look at it, there are more Chihuahuas and 'times' means multiply. Do you agree?
Therefore, I need to multiply 4 times the no. of Yorkies to get the no. of Chihuahuas
So, c = 4y
Now, I don't see an equation in the list to choose from. So, I don't know what to do from here. I am guessing that c = 4y is what you want.
If Debbie starts a retirement account with 10,000 dollars that has an annual rate of return of 12%, how long (in years) would it take for her to have at least 100,000 dollars if interest is compounded continuously?
Answer:
19.2 years
Step-by-step explanation:
The formula to find the time in a compound interest that is compounded continuously is given as:
t = ln(A/P) / r
Where:
t = time in years = ??
A = Amount after Interest is compounded continuously = $100,000
P = Initial Amount in the retirement account = $10,000
r = Rate of return = 12%
First, convert R percent to r a decimal
r = R/100
r = 12%/100
r = 0.12 per year,
Then, solve our equation for t
t = ln(A/P) / r
t = ln(100,000.00/10,000.00) / 0.12
t = 19.188 years
Approximately t = 19.2 years
Pls help just please will mark BRAINLIEST
Answer:
44.2545
Step-by-step explanation:
you can find the third angle by taking 180-(90+55)=a
a=35
use law of sines
Sin(angle)/(opposite side of angle)=Sin(another angle)/(opposite side of another angle)
so, sin(a)/A=sin(b)/B
sin(35)/33=sin(55)/x
x=sin(55)/(sin(35)/33)
x=44.2545

if a - b = 4 and a² - b² =12, what is the value of a + b?.
help.
Answer:
a² - b² = ± 32
Step-by-step explanation:
⇒ a + b = 4
⇒ a = 4 - b ... ( 1 )
Substituting this in another equation we get,
⇒ ab = -12
⇒ ( 4 - b ) ( b ) = -12
⇒ 4b - b² = -12
⇒ b² - 4b - 12 = 0
⇒ b² - 6b + 2b - 12 = 0
⇒ b ( b - 6 ) + 2 ( b - 6 ) = 0
⇒ ( b + 2 ) ( b - 6 ) = 0
⇒ b = -2, 6
Case 1: If b = -2
⇒ a = 4 - b
⇒ 4 - ( -2 ) = 4 + 2 = 6
Case 2: If b = 6
⇒ a = 4 - b = 4 - 6 = -2
Hence the numbers are 6 and -2.
⇒ a² - b² = ?
Case 1: a = 6 and b = -2
⇒ ( 6 )² - ( -2 )²
⇒ 36 - 4 = 32
Case 2: a = -2, b = 6
⇒ ( -2 )² - ( 6 )²
⇒ 4 - 36 = -32
Hence the answer for a² - b² can be ± 32 depending on the values of a and b.
