three consecutive odd integers have a sum of 51. what is the smallest integer
Answers
Answer:
15
Step-by-step explanation:
Let 2n+1 be the first odd integer.
Therefore, the consecutive odd integers will be 2n+3 and 2n+5
If the sum of the consecutive odd integers is 51 then:
⇒ 2n + 1 + 2n + 3 + 2n + 5 = 51
⇒ 6n + 9 = 51
⇒ 6n = 42
⇒ n = 7
To find the values of the integers, substitute the found value of n into the expressions:
First integer: 2(7) + 1 = 15Second integer: 2(7) + 3 = 17Third integer: 2(7) + 5 = 19Therefore, the three consecutive odd integers that sum to 51 are 15, 17 and 19. The smallest of which is 15.
g(x) = 1/4 x + 5
Find x when g(x) = 8
Answers
Answer:
\(g(x) = \frac{1}{4} x + 5 = 8 \\ \frac{1}{4} x = 8 - 5 \\ \frac{1}{4}x = 3 \\ x = 3 \times 4 \\ x = 12 \\ thank \: you \)
Answer:
x = 12
Step-by-step explanation:
G(x) = 1/4x +5 Now G(x) is also equal to 8
This means we can set the problems equal to each other since they both equal G(x)
1/4x + 5 = 8 Now we want to isolate the x, so we subtract both sides by 5
1/4x = 3 Now we multiply both sides by 4 to get rid of the fraction (were using reciprocals) (1/4 x 4 = 1 and 3 4 = 12)
x = 12

What is the slope of a line perpendicular to the line whose equation is 10x-12y=-24.
Answers
The slope of a line perpendicular to the line whose equation is 10x - 12y = -24 is 5/6
Given equation,
10x - 12y = -24
This line's parallel has the same slope as this line. Solve for y to alter the equation in order to calculate the slope.
y = mx + b
Where m is the slope and b is the y-intercept.
From the given equation,
10x - 12y = -24
-12y = -10x - 24
y = -10x/-12 + 24/12
y = 5x/6 + 2

how to find the area of a quadrilateral with coordinates
Answers
To find the area of a quadrilateral with given coordinates, you can use the Shoelace Formula.
The Shoelace Formula, also known as Gauss's area formula, provides a method to calculate the area of any polygon given its coordinates. Here's how it works for a quadrilateral:
Let's say you have the coordinates of the four vertices of the quadrilateral: (x1, y1), (x2, y2), (x3, y3), and (x4, y4).
1. Write down the coordinates in a clockwise order:
(x1, y1), (x2, y2), (x3, y3), (x4, y4), (x1, y1).
2. Multiply each x-coordinate by the y-coordinate of the next vertex.
For example, for the first vertex (x1, y1), multiply x1 by y2, and for the second vertex (x2, y2), multiply x2 by y3, and so on.
3. Multiply each y-coordinate by the x-coordinate of the next vertex.
For example, for the first vertex (x1, y1), multiply y1 by x2, and for the second vertex (x2, y2), multiply y2 by x3, and so on.
4. Add up all the results from Steps 2 and 3.
5. Take the absolute value of the sum calculated in Step 4 and divide it by 2.
By following the steps of the Shoelace Formula, you can calculate the area of a quadrilateral given its coordinates. Remember to ensure that the coordinates are listed in a clockwise or counterclockwise order to obtain the correct result. This method can be applied to any quadrilateral shape and provides an efficient way to find its area without requiring complex calculations or trigonometric functions.

Upload answer sheets Consider the relation schema RAB.CDE) with the following functional dupandencies FAB-SC DE AB-SE ESC) Compute the candidate toy for the given relation . Compute the minimal cover of F.
Answers
The correct answer is the minimal cover of F is:F = {AB→C, AB→S, AB→E, ES→S}
Given, relation schema R(ABC,DE) with functional dependencies F:AB→SCDE→ABAB→SEES→C.
The candidate key of a relation R is a minimal set of attributes that can uniquely identify each tuple in R. To find the candidate key, we can compute the closure of each subset of attributes in R. Let's begin by finding the closure of AB, the subset of R. We can use the functional dependency AB→SC to compute the closure of AB as follows: AB+ = ABSC (by AB→SC)
Next, let's compute the closure of DE, the other subset of R. We can use the functional dependency DE→AB to compute the closure of DE as follows: DE+ = DEABSE (by DE→AB and AB→SE)
Now we have two potential candidate keys, AB and DEABSE. However, we need to check if they are minimal. To do this, we check if any subset of these candidate keys can also function as a candidate key. We can see that neither AB nor DEABSE has any proper subset that can function as a candidate key.
Therefore, both AB and DEABSE are candidate keys for the relation R. Next, let's compute the minimal cover of F. The minimal cover of a set of functional dependencies F is a minimal set of functional dependencies that is equivalent to F.
To find the minimal cover of F, we can use the following steps:
Step 1: Eliminate redundant dependencies. We can eliminate the dependency AB→SC since it is implied by AB→C.
Step 2: Decompose dependencies. We can decompose the dependency AB→SE into two dependencies, AB→S and AB→E, since S and E are not a subset of any other attribute set in F.
Step 3: Eliminate extraneous attributes. We can eliminate the attribute C from the dependency ES→C since C is already determined by AB→C.
Therefore, the minimal cover of F is:F = {AB→C, AB→S, AB→E, ES→S}

years at 2.25% APR. The same loan at her savings bank has an APR of
2.9%. How much would Olivia save in finance charges if she joined the credit
union and took out her loan there? Round to the nearest ten dollars.
Answers
The amount hat Olivia would save in finance charges if she joined the credit union is $156.
How much would Olivia save?Finance charges are a form of compensation that is paid by the borrower to the lender for use of his or her funds. The finance charge is usually equivalent to the interest that would be paid on the loan.
The interest that would be paid on the loan would be determined using the simple interest formula. The interest paid is a function of the amount borrowed, the interest rate and the duration of the loan.
The APR represents the annual percentage rate. The higher the APR is, the higher the interest that would be paid on the loan. Thus, all things being equal, it is expected that the loan taken at 2.9 APR would be higher than the loan taken at 2.25% APR.
Interest paid = principal x APR x time
Interest paid if she borrows at 2.25% : 8,000 x 3 x 0.0225 = $540
Interest paid if she borrows at 2.9% : 8,000 x 3 x 0.029 = $696
The difference in interest that would be paid : $696 - $540 = $156

Answer: she saves about 80 bucks (because round)
Step-by-step explanation:
Step 1: Calculate her monthly payments using the monthly payment formula: P * r * (1 + r)^t / ((1 + r)^t - 1)
P = Principal ($8000)
r = Rate or APR
t = Time or Number of Months (3 years or 36 months in this case)
Credit Union: M = ($8000(.0225/12)(1+.0225/12)^36)/((1+.0225/12)^36-1) = $230.01
Savings Bank: M = ($8000(.029/12)(1+.029/12)^36)/((1+.029/12)^36-1) = $232.29
Step 2: Find the finance charge by multiplying your monthly payment with interest by the time in months, and subtracting your principal from that value:
Credit Union: ($230.01 x 36) - $8000 = $280.36
Savings Bank: ($232.29 x 36) - $8000 = $362.44
Step 3: Find how much she would save in finance charges compared to her other option. Subtract to find the difference:
$362.44 - $280.36 = $82.08
Step 4: Round to the nearest ten dollars:
$80.00
Olivia would save about $80 in finance charges if she loaned from the credit union instead her savings bank.

Answers
The given problem is a 0-1 integer programming problem, which involves finding the maximum value of a linear objective function subject to a set of linear constraints, with the additional requirement that the decision variables must take binary values (0 or 1).
To solve this problem by implicit enumeration, we systematically evaluate all possible combinations of values for the decision variables and check if they satisfy the constraints. The objective function is then evaluated for each feasible solution, and the maximum value is determined.
In this case, there are three decision variables: x1, x2, and x3. Each variable can take a value of either 0 or 1. We need to evaluate the objective function 2x1 - x2 - x3 for each feasible solution that satisfies the given constraints.
By systematically evaluating all possible combinations, checking the feasibility of each solution, and calculating the objective function, we can determine the solution that maximizes the objective function value.
The explanation of the solution process, including the enumeration of feasible solutions and the calculation of the objective function, can be done using a table or a step-by-step analysis of each combination.
This process would involve substituting the values of the decision variables into the constraints and evaluating the objective function. The maximum value obtained from the feasible solutions will be the optimal solution to the problem.

x is sin(30) in a circle with radius "diagonal length".
6 is cos(30) in the same circle.
6 = cos(30)×r

but we refer to the angle at the bottom right vertex.
remember, the sum of all angles in a triangle is always 180°.
so, the angle over there at the right is
180 - 90 - 68 = 22°
x = sin(22)×r
25 = cos(22)×r
r = 25/cos(22) = 26.96336857...
x = sin(22)×r = 10.10065565... ≈ 10.1

9 is the sine of the complementary angle of 49 in a circle with radius x.
the complementary angle is the angle that adds up with the original angle to 90° and is therefore

9 = sin(41)×x
x = 9/sin(41) = 13.71827778... ≈ 13.7
18.
we use the extended Pythagoras :
c² = a² + b² - 2ab×cos(C)
with c being the side opposite of the angle C.
so we have
LK² = 16² + 24² - 2×16×24×cos(29) =

LK = 12.66065026... ≈ 12.7
19.
law of sine
a/sin(A) = b/sin(B) = c/sin(C)
with the sides being always opposite to the corresponding angles.
to find the angle at H we need to find the angle at G first, because we don't know GF yet.
so,
28/sin(76) = 18/sin(G)
sin(G) = 18×sin(76)/28 = 0.623761538...
G = 38.59134528...°
remember the 180° rule in triangles.
H = 180 - 76 - G = 65.40865472...° ≈ 65.4°
20.
GF is now calculated using the law of sine again.
28/sin(76) = GF/sin(H)
GF = 28×sin(H)/sin(76) = 26.23980579... ≈ 26.2
