Answer:
The area of the quadrilateral is 1,182.46 m2.
Step-by-step explanation:
In order to find the area of a quadrilateral WXYZ, with WX=24m, XY=50m, YZ=40m, ZW=30m and the diagonal being 50m, the following calculation has to be done:
X = 0,5 24 × 30 × sen 24 + 0,5 × 50 × 40 × sen 40

The cost of a High Definition television now averages $700, but the cost is decreasing about 15% per year. In how many years will the cost be under $200?
Answer: 7.7 years
Step-by-step explanation:
Given
The cost of HD TV is $700 and it is decreasing at the rate of 15% per year
After one year it becomes
[tex]\Rightarrow 700-700\times 15\%\\\Rightarrow 700(1-0.15)[/tex]
after 2 year it becomes
[tex]\Rightarrow 700(1-0.15)-700(1-0.15)\times 15\%\\\Rightarrow 700(1-0.15)(1-0.15)\\\Rightarrow 700(1-0.15)^2[/tex]
Suppose, after x years it becomes $200
[tex]\Rightarrow 200=700(1-0.15)^x\\\\\Rightarrow \dfrac{2}{7}=0.85^x\\\\\text{Taking log both sides}\\\\\Rightarrow x=\dfrac{\ln (\frac{2}{7})}{\ln (0.85)}\\\\\Rightarrow x=7.7\ \text{years}[/tex]
Thus, it takes 7.7 years for the cost to come under $200.

Line segment AB has endpoints A(6, 4) and B(2, 6). Find the coordinates of the point that divides the line segment directed from A to B in the ratio of 1:3.
Answer:
(3, 5.5)
Step-by-step explanation:
Given the line segment AB with endpoints A(6, 4) and B(2, 6). If the coordinates of the point divide the line segment directed from A to B in the ratio of 1:3, then;
M(X, Y) = {(ax1+bx2)/a+b, ay1+by2/a+b}
X = ax1+bx2/a+b
X = 1(6) + 3(2)/1+3
X = 6+6/4
X = 12/4
X = 3
Similarly;
Y = ay1+by2/a+b
Y = 1(4)+3(6)/1+3
Y = 4+18/4
Y = 22/4
Y = 5.5
Hence the required coordinate is (3, 5.5)
Solve 3n – 5p + 2n = 10p for n.
Answer:
n = 3p
Step-by-step explanation:
3n−5p+2n=10p
5n−5p+5p=10p+5p
5n=15p
5n/5 = 15p/5
n = 3p
Answer:
3n+2n=10p+5p
5n=15p
Divide both sides by 5
n=3p
For the function f(x)= |x+2| -3 , explain the difference between f(2x) and 2f(x). Comparing the y-intercept , x-intercepts
Answer:
For a function f(x), the y-intercept is the value of f(0), while the x-intercepts are the values of x such that:
f(x) = 0.
Here we can also start with some information about dilations.
For a function f(x), a vertical dilation of scale factor k is written as:
g(x) = k*f(x)
While, again, for a function f(x), an horizontal dilation of scale factor k is written as:
g(x) = f(x/k)
So when here they ask us the difference between f(2x) and 2f(x)
We can say that the first one is a horizontal dilation of scale factor 1/2, while the second is a vertical dilation of scale factor 2.
Now let's analyze the intercepts for each case.
if f(x) = |x + 2| - 3
2*f(x) = 2*(|x + 2| - 3)
= 2*|x + 2| - 6
The y-intercept is:
2*f(0) = 2*|0 + 2| - 6 = 4 - 6 = -2
and the x-intercepts are given by:
2*f(x) = 0 = 2*|x + 2| - 6
6 = 2*|x + 2|
6/2 = |x + 2|
3 = |x + 2|
Here we have two solutions for x,
x = 1: 3 = |1 + 2| = |3| = 3
x = -5: 3 = |-5 + 2| = |-3| = 3
Now for the other transformation, we have:
f(2*x) = |2*x + 2| - 3
the y-intercept is:
f(2*0) = |2*0 + 2| - 3
= |2| - 3 = -1
(So the y-intercept is different)
And the x-intercepts are given by:
f(2*x) = 0 = |2*x + 2| - 3
3 = |2*x + 2|
3 = 2*|x + 1|
3/2 = |x + 1|
Here the two solutions are:
x = 1/2
x = -5/2
So the x-intercepts are also differents.
This happens because in one case, we affect the function horizontally and in the other case vertically, so one could expect that the resulting functions are different (thus, have different intercepts)

Answer:
a) 20 km away fro the starting point.
b) The bearing from P to R is 80°.
c) Q is 60 km North P.
d) Q is - 60 km west of P
Step-by-step explanation:
Stating Facts in the Question:
P to Q is 80 km and bearing 330°
It turned around, Q to R is 60 km and bearing 250°.
a) Picture a number line (Look at the first image)
You go 80 to the right. You turn around and go 60 to the left.
80 - 60 = 20
20 km away fro the starting point
b) Picture a number line (Look at the second image)
P to Q is bearing 330°
Q to R is 60 km is bearing 250°
P to Q is red
Q to R is blue
330° - 250° = 80°
The bearing from P to R is 80°
c) P to Q is 60 km
The plane went forward or North so the answer is 60 km.
Q is 60 km North P.
d) Q to P is 60 km
Q is not to the west of P
Q is - 60 km west of P

Water is a compound made up of two hydrogen and one oxygen.
What are Compounds?Compounds are chemical substances formed by the combination of two or more different elements.
Here consider the compound Water.
A Water molecule is made up of two hydrogen atoms and one oxygen atom.
The molecular formula is H₂O.
Consider the element hydrogen from water.
Hydrogen is an element which does not have any smell and does not have color.
In the room temperature, hydrogen exists in gaseous state. It will turn in to liquid at low temperature and high pressure.
Hence water is a compound made up of two hydrogen and one oxygen.

A school bus has 25 seats, with 5 rows of 5 seats. 15 students from the first grade and 5 students from the second grade travel in the bus. How
many ways can the students be seated if all of the second-grade students occupy the first row?

OD. SPs *15P15
OE PSX25C5
Answer:
B. [tex]^{5} P_{5}[/tex] × [tex]^{20} P_{15}[/tex]
Step-by-step explanation:
No. of students from first grade = 15
No. of students from second grade = 5
There are 5 rows of seats
Each row contains 5 seats
Total seats = 25
No. of ways for second-grade students to occupy the first row (i.e first 5 seats) = [tex]^{5} P_{5}[/tex]
Remaining seats = 20
So, now we are left with 15 first grade students
So, No. of ways for first-grade students occupy remaining seats = [tex]^{20} P_{15}[/tex]
Using the counting rule principle,
No. of ways for the students can be seated if all of the second-grade students occupy the first row = [tex]^{5} P_{5}[/tex] × [tex]^{20} P_{15}[/tex]
So, Option B is the correct answer
Hence, no. of ways for the students can be seated if all of the second-grade students occupy the first row is ×
There are ¹⁵P₁₅ x ¹⁰P₅ possible way to seat, if all of the second-grade students occupy the first row.
What is permutation?A permutation in math is the number of ways in which a set of data or objects can be ordered or arranged, where the order matters.
Given that, a school bus has 25 seats, with 5 rows of 5 seats. 15 students from the first grade and 5 students from the second-grade travel in the bus.
Since you have to place all first-grade students in the first three rows,
Therefore,
For the 15 first-graders of the first three rows (15 seats), we have ¹⁵P₁₅ since all 15 places have to be occupied by all 15 first-graders.
Then we have 10 remaining seats left to be assigned to the 5 second-graders = ¹⁰P₅
We then multiply the permutation numbers of those two arrangements to get the total ways:
¹⁵P₁₅ x ¹⁰P₅
Hence there are ¹⁵P₁₅ x ¹⁰P₅ possible way to seat, if all of the second-grade students occupy the first row.

This is a trinomial of the form ax^2 + bx + c, where a is not 1.
Step 1: Try to factor out a common factor.
In this case, there is no common factor in all terms.
We will now factor by grouping.
Step 2. Find the product ac.
ac = 2 * 10 = 20
Step 3. Find two factors of ac whose product is ac and whose sum is b.
In this case, we need two numbers whose product is 20 and whose sum is 9.
Those numbers are 4 and 5.
Step 4. Break up the middle term using the two numbers we just found.
9x becomes 4x + 5x
Now we have
= 2x^2 + 4x + 5x + 10
Step 5. Factor by grouping. Factor a common factor out of the first two terms. Factor a common factor out of the last two terms.
= 2x(x + 2) + 5(x + 2)
Finally, factor out the common factor, x + 2.

Concrete can be purchased by the cubic yard. How much will it cost to pour a slab 11 feet by 11 feet by 2 inches for a patio if the concrete costs $46.00 per cubic yard?
Answer:
$34.04
Step-by-step explanation:
The dimensions of a slab is 11 feet by 11 feet by 2 inches or 3.67 yards, 3.67 yards and 0.055 yards
We need to find the cost to pour a slab.
We know that the volume of a cuboid shape is given by :
V = lbh
Put all the values,
V = 3.67 × 3.67 × 0.055
V = 0.74 yards³
Cost,
C = $46 × 0.74
C = $34.04
Hence, the required cost is equal to $34.04.
