Find three consecutive even integers such that the product of the first and second is 8 more than 38 times the third.
Answer:
40, 42 and 44
Step-by-step explanation:
Mark these even consecutive integers as (2n-2), 2n and (2n+2)
Note that since they are integers, n > 0 and 2n is always even
Writing the equation
(2n-2) * 2n = 38 * (2n+2) + 8
// divide both sides by 2
(2n-2) * n = 19 * (2n+2) + 4
[tex]2n^{2}[/tex] - 2n = 38n + 38 + 4
[tex]2n^{2}[/tex] - 2n - 38n - 38 - 4 = 0
[tex]2n^{2}[/tex] - 40n - 42 = 0
// divide both sides by 2
[tex]n^{2}[/tex] - 20n - 21 = 0
// rewrite the equation
[tex]n^{2}[/tex] + n - 21n - 21 = 0
n * (n+1) - 21n - 21 = 0
n * (n+1) - 21 * (n+1) = 0
(n+1) * (n-21) = 0
// separate the two possible cases
n + 1 = 0 and n - 21 = 0
n = -1 n = 21
Note that here n has to be an integer, so case n = -1 can't be a solution. Therefore we use n = 21
Calculating the consecutive even integers
2n - 2 = 2 * 21 - 2 = 40
2n = 2 * 21 = 42
2n + 2 = 2 * 21 + 2 = 44

The slope of the table is 2
What is slope?In mathematics, the slope or gradient of a line is a number that describes both the direction and the steepness of the line. The slope of a line is a measure of its steepness. Mathematically, slope is calculated as "rise over run" (change in y divided by change in x).
here, we have,
to determine the slope:
From the table, we have the following points:
(x,y) = (0, 4) and (1,7)
The slope is then calculated as:
m = (y2 - y1)/(x2 - x1)
Substitute known values
m = (7 - 4)/(1 - 0)
Evaluate the differences
m = 3/1
Divide
m = 2
Hence, the slope of the table is 2

Segment AB is being dilated with the center at the origin. The image of A, point A prime, has coordinates of (3.2, 6.4). What is the scale factor of the dilation and the coordinates of point B prime?
Step-by-step explanation:
The location of A is 3.2
The location of A' is 6.4
A represent pre image A' represent the new image.
The scale factor of A to A' is 2 since 3.2 x 2 =6.4
Since you didnt provide B coordinates, just multiply 2 by the B coordinate to find the B prime coordinate.
Answer: A.)The scale factor is 0.8 and the coordinates of point B prime are (–3.2, –4.8).

Which equation has a slope of -2 and passes through the point (1, -6)?
A. y = -23 – 4
B. Y = -22 that
c. y = –2x – 8
D. Y = -2x + 8
Answer:
C. y= -2x-8 is the answer
Answer:
y = -2x - 4
Step-by-step explanation:
y = mx + b(we substitute the "x" and "y" points into this general formula)
-6 = -2 (1) + b ( multiply "-2" by "1" and obtain the answer itself "-2")
(+ 2) -6 = -2 + b (+ 2)( then we add "2" on both side so the right side will be left with only "b". and "-6 + 2 = -4")
-4 = b( we substitute this answer in the general formula we've written )
y= -2x -4
b) If f(2x - 3) = 4x + 5, then find f(x) and f(-2).
c) If f(x) = 7* then prove that
f(m + n + p) = f(m) . f(n) f(p)
pls solve at least 1 only if u know
f(2x-3)=4x+5
Let, 2x-3=g
x=(g+3)/2
So,f(2{g+3}/2 -3)=4(g+3)/2 + 5
f(g)=2g+11
So,f(x)=2x+11
f(-2)=7 ##
Answer:
f(2x - 3) = 4x + 5
f(2x-3)=2(2x-3)+11
f(x)=2x+11
f(-2)=2×-2+11=-4+11=7

The period of a pendulum is the time the pendulum takes to swing back and forth. The function L=0.81t^2 relates the length L in feet of a pendulum to the time t in seconds that it takes to swing back and forth. A convention center has a pendulum that is 50 feet long. Find the period.
Answer:
7.86seconds
Step-by-step explanation:
Given the expression used to model the length of the pendulum as
L=0.81t^2 where t is the period
IF the pendulum is 50 feet long, then L = 50 feet
Substitute
50 = 0.81t^2
t² = 50/0.81
t² = 61.7283
t = 7.86 seconds
Hence the period is 7.86seconds
The point (4,3.5) is the maximum of the profit function.
A.Explain what the point (4,3.5) represents in terms of the context of the graph.
The function shown describes f(x), the cost (in hundreds of thousands of dollars) of making x bicycles (in thousands).
F(x)=1.25+0.35x
B.what is the cost to make 4,000 bicycles? Show your work.
Compare the slope of the cost function with the graph of the profit function.
C. Explain why the company should plan on making fewer than 4,000 bicycles.
Answer:
A. The point represents the turning point of the graph
B. The cost of making 4,000 bicycles is $265,000
The slope of the cost function, F(x) = 1.25 + 0.35·x, is less than the average slope of the graph of the total profit for sales
C. The company should plan on making fewer than 4,000 bicycles, to maximize profit
Step-by-step explanation:
A. The point represents the turning point after which increase in the x-coordinate values leads to a decrease in the y-coordinate values
B. The cost function is presented as follows;
F(x) = 1.25 + 0.35·x
Where;
F(x) = The cost in hundreds of thousands of dollars of making 'x' (in thousands) bicycles
x = The number of bicycles made in thousands
The cost of making 4,000 bicycles is given by plugging in x = 4(thousand) in F(x) = 1.25 + 0.35·x, as follows;
F(x) = 1.25 + 0.35·x
∴ F(4) = 1.25 + 0.35 × 4 = 2.65
Therefore, the cost of making 4,000 bicycles = 2.65 × $100,000 = $265,000
The slope of the cost function, F(x) = 1.25 + 0.35·x, is given by the coefficient of 'x' which is 0.35
The average slope of the graph of the profit function is ((3.5 - 0)/(4 - 0)) = 0.875
The slope of the cost function is less than the average slope of the graph of the profit function taken from the origin to the maximum point of the graph
C. When the company produces 5,500 bicycles, x = 5.5, we have;
F(5.5) = 1.25 + 0.35 × 5.5 = 3.175
The cost is 3.75 × $100,000 = $375,000 and the profit from te graph is $300,000
Therefore, the cost of making the 5,500 bicycles is more than the profit made in sales
The company should plan on making fewer than 4,000 bicycles, to reduce cost of producing more bicycles and to increase profit per unit of bicycle sold

The sum of three numbers is 212 .If the ratio of the first to the second is 13:16 and that of the second to the third is 2:3 then find the numbers.`
Given:
The sum of three numbers is 212 .
The ratio of the first to the second is 13:16 and that of the second to the third is 2:3.
To find:
The unknown numbers.
Solution:
We have,
First : Second = 13:16
Second: Third = 2:3
We need to combine these ratios, to get a single ratio for all three numbers.
Second: Third = 2×8:3×8 = 16:24
Now,
First: Second: Third = 13:16:24
Let the first, second and third numbers are 13x, 16x and 24x respectively.
[tex]13x+16x+24x=212[/tex]
[tex]53x=212[/tex]
[tex]x=\dfrac{212}{53}[/tex]
[tex]x=4[/tex]
So, the numbers are,
[tex]First=13x[/tex]
[tex]First=13(4)[/tex]
[tex]First=52[/tex]
Similarly,
[tex]Second=16x[/tex]
[tex]Second=16(4)[/tex]
[tex]Second=64[/tex]
And,
[tex]Third=24x[/tex]
[tex]Third=24(4)[/tex]
[tex]Third=96[/tex]
Therefore, the three unknown numbers are 52, 64, 96.

Step-by-step explanation:
round it if you have to
Answer:
75 cm
Step-by-step explanation:
The diagonal d divides the rectangle into 2 right triangles with d as the hypotenuse.
Using the right triangle formed on the left and using Pythagoras' identity.
The square on the hypotenuse is equal to the sum of the squares on the other 2 sides, that is
d² = 45² + 60² = 2025 + 3600 = 5625 ( take square root of both sides )
d = 75
The diagonal is 75 cm

Slope of BC = [tex]\frac{-1+5}{2-2}[/tex]
= Not defined (Parallel to y-axis)
Slope of AB = slope of DC = [tex]-\frac{2}{3}[/tex]
Slope of BC = slope of AD = Not defined (parallel to y-axis)
As per property of a parallelogram,
"Opposite sides of a parallelogram are parallel and equal in measure"
Therefore, ABCD is a parallelogram.
If ABCD is a parallelogram, find the measure of angle C
Answer:
47
Step-by-step explanation:
Angles B and D are equal.
Angles A and C are equal.
Anges in parallelogram add up to 360°
5x+38=8x-19
57=3x
x=19
B=(5×19)+38=133°
D=(8×19)-19=133°
A+C=360-133-133
A+C=94
A and C are the same so you can do 94/2=
Therefore, both angles A and C are 47 :D
The measure of angle c in the parallelogram is 47°.
What is a parallelogram?A parallelogram is a quadrilateral (has four sides and four angles) in which opposite sides are parallel and equal. Also, opposite angles are equal and the shape has equal diagonals.
∠B = ∠D (opposite angles are equal)
8x - 19 = 5x + 38
x = 19
∠B = 5(19) + 38 = 133°
∠C + ∠B = 180° (base angles of parallelogram_
∠C + 133 = 180
∠C = 47°
