A relative maximum is a highest point in that little area.  Think of it as a top to a mountain in a mountain range.  It's a peak, but it might not be the tallest peak.

A relative minimum is the lowest point in that little area.  Think of it as a the bottom of a valley in some area.  It's possibly one of many valleys, so might not be the deepest valley.

When we talk about where these things happen, we describe them based on their x-values.  They happen at the x-value of that peak or valley.

There's a little peak on the left side and the x-value of that peak is x = -1.2.

There's a little valley on the right side and the x-value of that valley is x = 1.2.

The answer is A.

i) To calculate the profit if 0 cakes are made per day, we can substitute x = 0 into the function:

P(x) = -x²+36x - 40

P(0) = -0² + 36(0) - 40 = -40 dollars

So, the profit from making 0 cakes per day is -40 dollars.

ii) To calculate the profit if 20 cakes are made per day, we can substitute x = 20 into the function:

P(x) = -x²+36x - 40

P(20) = -20² + 36(20) - 40 = 760 dollars

So, the profit from making 20 cakes per day is 760 dollars.

b) To find out how many cakes need to be made per day for the profit to be $270, we need to solve the equation P(x) = 270.

We can substitute the function P(x) into this equation:

-x²+36x - 40 = 270

Next we can solve this equation for x by using any method you prefer ( factoring, Quadratic formula, etc)

x = (36 +/- √(36² -4*(-40)(-1)))/ 2(-1)

x = (36 +/- √(1296 + 320))/ -2

x = (36 +/- √1616)/ -2

x = (36 +/- 40)/ -2

x = -2 +/- 20

x = 18 or -22

The number of cakes need to be made per day for the profit to be $270 is 18 or -22, but -22 is not a valid solution because the number of cakes must be a non-negative value, so the number of cakes need to be 18

The amount of water in Casandra's bowl, given the gallons of water it can hold and the fraction full it is, is 0.6 gallons

Casandra' s fish bowl is able to hold a total of 9 / 10 gallons of water which is also 0.9 gallons of water. This means that you can find out how much water is in the bowl if told the fraction of the bowl that is currently full up to.

This time, the bowl is said to be 2 / 3 full which means that out of the capacity of 9 / 10 gallons or 0 . 9 gallons, the bowl is two - thirds full.

The amount of water in the bowl is therefore:

= Capacity of fish bowl x Proportion of water in the bowl

= 9 / 10 x 2 / 3

= 0. 9 x 2 / 3

Answer:

We can use the equation:

amount of a given nutrient / % of recommended daily amount = recommended daily amount

Here, we know that 69 grams of carbohydrates is 22% of the recommended daily amount, so we can plug in the given values and solve for the recommended daily amount:

69 / 0.22 = Recommended Daily Amount

Recommended Daily Amount = 69 / 0.22 = 313.64 grams (rounded to one decimal place)

So, the total recommended daily amount of carbohydrates in grams is 313.6 grams.

The expression for the perimeter of the right triangle with hypotenuse 2p + 8 and base p - 5 is: perimeter = (p - 5) + sqrt((2p + 8)^2 - (p - 5)^2) + (2p + 8)

What is triangle ?

Triangle can be defined in which it consists of three sides, three angles and sum of three angles is always 180 degrees.

In a right triangle, the hypotenuse (the longest side) is opposite the right angle, and the other two sides are called the legs. In this case, the hypotenuse is 2p + 8 and one of the legs (the base) is p - 5.

To find the third side (the other leg), we can use the Pythagorean theorem, which states that in a right triangle, the square of the hypotenuse is equal to the sum of the squares of the legs. In other words:

(hypotenuse)^2 = (leg 1)^2 + (leg 2)^2

Substituting the given values, we get:

(2p + 8)^2 = (p - 5)^2 + (leg 2)^2

Simplifying and solving for leg 2, we get:

leg 2 = sqrt((2p + 8)^2 - (p - 5)^2)

Now we can use the perimeter formula, which is the sum of the lengths of all the sides of the triangle. In this case, the perimeter of the triangle is:

perimeter = (leg 1) + (leg 2) + (hypotenuse)

Substituting the given values and the expression we found for leg 2, we get:

perimeter = (p - 5) + sqrt((2p + 8)^2 - (p - 5)^2) + (2p + 8)

Therefore, the expression for the perimeter of the right triangle with hypotenuse 2p + 8 and base p - 5 is: perimeter = (p - 5) + sqrt((2p + 8)^2 - (p - 5)^2) + (2p + 8)

d)  The percentage change in nominal GDP between 2010 and 2019 attributed to changing prices is; 24.45%

The formula to calculate percentage change is;

Percentage change = (Final Value - Original Value)/Original Value * 100%

a) The percentage change in nominal GDP between 2010 and 2019 is;

(21433 - 14527)/14527 * 100%

b) Real GDP in 2019 at prices of 2010 is;

21433 * 0.961

= 20,597.113 billions

c)  The percentage change in real GDP between 2010 and 2019;

real GDP in 2010 = 14527 * 0.961

= 13,960.447 billion

Real GDP in 2019 = 21433 * 1.123

= 24,069.259 billion

Percentage change =  (24069.259 - 13960.447)/13960.447 * 100%

= 72.4%

d)  The percentage change in nominal GDP between 2010 and 2019 attributed to changing prices is;

Percentage change = [(21433/1.123) - (14527/0.961)]/(14527/0.961) * 100%

Answer:

The slope is -1

The y-intercept is -8

The equation is y = -x -8

Step-by-step explanation:

The slope is the change in y over the change in x.  As the y is decreasing by 1.  The x is increasing by 1

-1/1 = -1  

The slope is -1.

The y-intercept is the y value when the x value is 0.  When x = 0, y = -8

The y-intercept is -8.

y = mx + b

y = -1x - 8  I don't nee the 1 so I am going to write it without it.

Step-by-step explanation:

Answer:

Part A:

To find the length of the ramp in yards, we need to first determine the horizontal distance covered by the ramp. The slope of the ramp is 1/12, meaning that for every 12 inches of horizontal distance, the height of the ramp increases by 1 inch. Since the height of the ramp when it connects to the house is 9 inches, we can use this information to determine the horizontal distance covered by the ramp.

9 inches / (1/12) = 108 inches

To convert inches to yards, we divide by 36, so

108 inches / 36 inches/yard = 3 yards

Part B:

To determine the length of the ramp, I used the information provided about the slope of the ramp and the height of the ramp when it connects to the house. I used the slope of the ramp (1/12) to calculate the horizontal distance covered by the ramp. Then I converted the horizontal distance from inches to yards by dividing by 36. Finally, I obtained 3 yards as the length of the ramp.

Answer:

Part A = 3 yards

Part B = 9 x 12 = 108 inches = 9 feet = 3 yards

Step-by-step explanation:

Part A

1 inch height - 12 inches length

9 inches height - 9 x 12 = 108 inches length

36 inches = 1 yard

108 inches = 108/36 = 3 yards

Part B

Shown above

The ramp is 9 inches tall, so the length of the ramp is 9 x 12 = 108 inches.

1 feet = 12 inches

108 inches = 108/12 feet = 9 feet

1 yard = 3 feet

9 feet = 3 yards.
