multiply 280 by 100, and you get 28000. divide this by 2000, and you get 14!
The value of a particular used car has been decreasing at the same rate each year since 2010. The equation C (t) 25,000 (0.78) represents
the value of the car C' (t), in dollars, as a function of t, the number of years since 2010.
What is the percent decrease of the value of the car each year?
O22%
The percentage decrease in the value of the car is 22%.
What is the percent decrease?We need to know that when we are talking about the increase or the decrease we are dealing with an exponential function. As such, we would have to look at the general form of the exponential equation as we deal with the problem.
Now we have that the general form of the equation ought to be;
Ct = Co(1 - r)^t
We would now compare the part (1 - r)^t with (0.78) ^t in the equation that we are given and we have;
1 - r = 0.78
r = 0.22
r = 22%

To win a carnival game, you have to shoot a stream of water into a clown's mouth. the clown face is painted on a rectangular piece of wood that measures 16 inches by 12 inches. the clown's mouth is a circle with a diameter of 3 inch. what is the probability that your water will hit the clown's mouth?
write the probability as a percentage, rounded to the nearest tenth.
The probability will be 0.037 or 3.7% when it is rounded to the nearest tenth.
To calculate the probability of hitting the clown's mouth, we need to compare the area of the clown's mouth to the total area of the rectangular wood piece.
The area of the clown's mouth can be found using the formula for the area of a circle: A = π * (r^2), where r is the radius. In this case, the diameter is given as 3 inches, so the radius is 1.5 inches.
Plugging the values into the formula, we get A = π * (1.5^2) = 7.065 square inches. The total area of the rectangular wood piece is 16 inches * 12 inches = 192 square inches.
Therefore, the probability of hitting the clown's mouth is 7.065 / 192 ≈ 0.0367, which rounds to 0.037 or 3.7% when expressed as a percentage rounded to the nearest tenth.

Hello people ~
factorise : 3x² + 10x + 8
Answer:
(x + 2)(3x + 4)
Step-by-step explanation:
3x² + 10x + 8
consider the factors of the product of the coefficient of the x² term and the constant term which sum to give the coefficient of the x- term.
product = 3 × 8 = 24 and sum = + 10
the factors are + 6 and + 4
use these factors to split the x- term
3x² + 6x + 4x + 8 ( factor first/second and third/fourth terms )
= 3x(x + 2) + 4(x + 2) ← factor out (x + 2) from each term
= (x + 2)(3x + 4) ← in factored form
\(\\ \rm\Rrightarrow 3x^2+10x+8\)
\(\\ \rm\Rrightarrow 3x^2+6x+4x+8\)
\(\\ \rm\Rrightarrow 3x(x+2)+4(x+2)\)

Sum of Square Error (SSE), tells us
O the sum of squares of the dependent variables
O the squares of the slope and intercept term
O the squares of the mean values of X and Y
O how well a model represents and explains the data
O how much of the dependent variation the model does not explain
SSE (Sum of Square Error) tells us how much of the dependent variation the model does not explain.
SSE is a measure that quantifies the difference between the observed values and the predicted values from a statistical model. It represents the sum of the squared differences between the actual values of the dependent variable and the predicted values by the model.
The SSE reflects the unexplained or residual variation in the data, meaning it represents the portion of the dependent variable's variability that is not accounted for by the model. In other words, it measures how well the model fits the data and captures the extent to which the model represents and explains the observed data. A lower SSE value indicates a better fit of the model to the data, as it implies that the model explains a larger proportion of the dependent variable's variation.
Therefore, option "O how much of the dependent variation the model does not explain" is the correct statement that describes what SSE tells us. It provides a measure of the unexplained variation in the data and serves as a basis for assessing the model's goodness of fit.

Which equations have the same value of x as Three-fifths (30 x minus 15) = 72? Select three options.
18 x minus 15 = 72
50 x minus 25 = 72
18 x minus 9 = 72
3 (6 x minus 3) = 72
x = 4.5
The correct answer is "None of the options." the same value of x as the given equation Three-fifths(30x - 15) = 72.
To find the equations that have the same value of x as the given equation, we need to solve the equation Three-fifths(30x - 15) = 72 and check which options satisfy the same value of x.
Let's solve the given equation step by step:
Three-fifths(30x - 15) = 72
Multiply both sides by the reciprocal of three-fifths, which is five-thirds:
(5/3) * Three-fifths(30x - 15) = (5/3) * 72
Simplifying:
(30x - 15) * (5/3) = 120
Multiply both sides by 3/5 to isolate (30x - 15):
(30x - 15) = (120) * (3/5)
Simplifying:
30x - 15 = 72
Add 15 to both sides:
30x = 87
Divide both sides by 30:
x = 87/30
Now, let's check which options have the same value of x:
a) 18x - 15 = 72:
Substituting x = 87/30:
18 * (87/30) - 15 = 72
26.1 - 15 = 72
11.1 ≠ 72
b) 50x - 25 = 72:
Substituting x = 87/30:
50 * (87/30) - 25 = 72
145 - 25 = 72
120 ≠ 72
c) 18x - 9 = 72:
Substituting x = 87/30:
18 * (87/30) - 9 = 72
52.2 - 9 = 72
43.2 ≠ 72
d) 3(6x - 3) = 72:
Simplifying:
18x - 9 = 72
Substituting x = 87/30:
18 * (87/30) - 9 = 72
52.2 - 9 = 72
43.2 ≠ 72
Based on our calculations, none of the options have the same value of x as the given equation Three-fifths(30x - 15) = 72. Therefore, the correct answer is "None of the options."

Trevor earned $25.00 making pizzas on Tuesday. He earned more money-making pizzas on Wednesday. Write an expression that shows the amount of money Trevor has earned.
An expression that represents the amount of money Trevor has earned can be written by adding the amount he earned on Tuesday to the amount he earned on Wednesday.
Let's denote the amount of money Trevor earned on Wednesday as "x". Since Trevor earned $25.00 on Tuesday, we can represent this amount as a constant value. To calculate the total amount of money Trevor has earned, we add the earnings from both days.
The expression that represents the amount of money Trevor has earned is:
$25.00 + x
Here, $25.00 represents the earnings on Tuesday, and "x" represents the earnings on Wednesday. By adding these two values, we obtain the total amount of money Trevor has earned.

Given the function f(t)=(t−3)(t+4)(t−2) its f-intercept is its t-intercepts are Question
The given function is f(t) = (t-3)(t+4)(t-2). We need to find the f-intercept and t-intercepts of this function.
The f-intercept of a function represents the point where the graph of the function intersects the y-axis, which is the line t = 0. To find the f-intercept, we substitute t = 0 into the function f(t) and solve for f(0). This will give us the y-coordinate of the point where the graph intersects the y-axis.
To find the t-intercepts of a function, we set the function equal to zero and solve for t. In this case, we set f(t) = 0 and solve the equation (t-3)(t+4)(t-2) = 0 for t. The values of t that satisfy this equation will give us the x-coordinates of the points where the graph intersects the x-axis.
By performing the necessary calculations, we can find the f-intercept and the t-intercepts of the given function.

(If an answer does not exist, enter DNE.)fx(0, 0) =fy(0, 0) =(c) Are both partial derivatives of f continuous at every point in the set {(x, y): (x, y) ≠ (0, 0)}?a. Yes, both the partial derivatives are continuous at every point in that set.b. No, only the partial derivative with respect to y is continuous at every point in that set.c. No, only the partial derivative with respect to x is continuous at every point in that set.d. No, neither partial derivative is continuous at every point in that set.
(a) To find the partial derivatives, we differentiate the function f(x, y) with respect to x and y while treating the other variable as a constant.
fx(x, y) = d/dx [ (4x^2 + 2xy + 4y^2) / (x^2 + y^2) ]
= [(8x(x^2 + y^2) - (4x^2 + 2xy + 4y^2)(2x)) / (x^2 + y^2)^2]
= [(8x^3 + 8xy^2 - 8x^3 - 4x^2y - 8xy^2) / (x^2 + y^2)^2]
= [-4x^2y / (x^2 + y^2)^2]
fy(x, y) = d/dy [ (4x^2 + 2xy + 4y^2) / (x^2 + y^2) ]
= [(8y(x^2 + y^2) - (4x^2 + 2xy + 4y^2)(2y)) / (x^2 + y^2)^2]
= [(8xy^2 + 8y^3 - 8xy^2 - 4x^2y - 8y^3) / (x^2 + y^2)^2]
= [-4x^2y / (x^2 + y^2)^2]
(b) To find fx(0, 0) and fy(0, 0), we substitute x = 0 and y = 0 into the partial derivative expressions:
fx(0, 0) = -4(0)^2(0) / ((0)^2 + (0)^2)^2 = 0
fy(0, 0) = -4(0)^2(0) / ((0)^2 + (0)^2)^2 = 0
(c) Both partial derivatives, fx(x, y) and fy(x, y), are continuous at every point in the set {(x, y): (x, y) ≠ (0, 0)}.
However, at the point (0, 0), the partial derivatives fx(0, 0) and fy(0, 0) are both 0, indicating that the partial derivatives are continuous at that point as well.
Therefore, the correct answer is (a) Yes, both the partial derivatives are continuous at every point in that set.
