Consider the function f(x) = 2x^2 - 4x + 9. Evaluate 2f(3) + 3f(-3).
Answers
Answer: 147
Step-by-step explanation:
To evaluate 2f(3)+3f(-3), we first need to find the values of f(3) and f(-3). Given f(x), we just plug in x=3, -3 into f(x).
f(3)=2(3)²-4(3)+9 [exponent]
f(3)=2(9)-4(3)+9 [parenthesis]
f(3)=18-12+9 [subtract]
f(3)=6+9 [add]
f(3)=15
Now, we find f(-3).
f(-3)=2(-3)²-4(-3)+9 [exponent]
f(-3)=2(9)-4(-3)+9 [parenthesis]
f(-3)=18+12+9 [add]
f(-3)=30+9 [add]
f(-3)=39
With the values of f(3) and f(-3), we can evaluate the expression.
2(15)+3(39) [multiply]
30+117 [add]
147
Now, we know the value is 147.

The circumference of a circular park is approximately 18 feet. What is the approximate area inside the circular park?
Answers
Answer:
25.685 square feet.
Step-by-step explanation:
Circumference = 2 * π * radius
From this, we can derive the formula for the radius:
radius = Circumference / (2 * π)
Let's substitute the value of the circumference and calculate the approximate radius:
radius = 18 / (2 * π)
radius ≈ 18 / (2 * 3.14159)
radius ≈ 2.865 feet
Now that we have the approximate radius, we can calculate the area:
Area ≈ π * radius²
Area ≈ 3.14159 * (2.865)²
Area ≈ 3.14159 * 8.193225
Area ≈ 25.685 square feet
Therefore, the approximate area inside the circular park is approximately 25.685 square feet.
C = 2πr
where C is the circumference and r is the radius of the circle.
In this case, we are given that the circumference is approximately 18 feet, so we can set up the following equation:
18 = 2πr
Solving for r, we get:
r = 9/π ≈ 2.864 feet
Now we can use the formula for the area of a circle:
A = πr^2
Substituting the value we found for r, we get:
A = π(2.864 ft)^2 ≈ 25.85 ft^2
Therefore, the approximate area inside the circular park is approximately 25.85 square feet.

PLEASE HELP ASAP!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
Answers
Answer:
6
Step-by-step explanation:
18-2.5+7 there s your helllppppppppppp
New base = 18 x 2/5 = 7.2 feet
New height = 7 x 2/5 = 2.8 feet
Therefore, the dimensions of the new deck are 7.2 feet for the base and 2.8 feet for the height.
Part B: To find the area of the original deck, we can use the formula for the area of a triangle, which is:
Area = (1/2) x base x height
Area = (1/2) x 18 x 7 = 63 square feet
To find the area of the new deck, we can use the same formula and plug in the new dimensions:
Area = (1/2) x 7.2 x 2.8 = 11.88 square feet
Therefore, the area of the original deck is 63 square feet and the area of the new deck is 11.88 square feet.
Part C: The ratio of the areas is:
63/11.88 = 5.303
The scale factor is:
2/5 = 0.4
To compare the ratio of the areas to the scale factor, we can divide the ratio of the areas by the scale factor:
5.303/0.4 = 13.2575
Therefore, the ratio of the areas is 13.2575 times the scale factor.

If a widget factory as a fixed operating cost of $2,500 per day plus a cost of $1.50 per widget produced. If a widget sells fro $5.00, what is the least number of widgets that must be sold per day to make a profit?
Answers
Answer:
At least 714 numbers of widgets must be sold per day to make a profit.
Given fixed operating cost = $2,500 per day cost of widget =$ 1.50
widget sells =$ 5.00
Cost function = C(X)=1.50x+2500
Revenue function = R(X)=5 x
At Break Even point R (X) = C (X)5
X= 1.50X+2003.5
X =2500X =714
Hence to reach break even point or make profit 714 no to be sold. R(714)= 3571.

Weights of Dogs in Shelter A
2 box plots. The number line goes from 6 to 30. For the weights of dogs in shelter A, the whiskers range from 8 to 30, and the box ranges from 17 to 28. A line divides the box at 21. For shelter B, the whiskers range from 10 to 28, and the box ranges from 16 to 20. A line divides the box at 18.
Weights of Dogs in Shelter B
Which describes the spread of the data in the two box plots?
The data in shelter A show more spread than the data in shelter B.
The data in shelter B show more spread than the data in shelter A.
