1 Latisha and Maisha are twins. They have a brother who is eleven years younger than
them and an older sister who is four years older. The sum of the ages of all four siblings
is 73. Find Latisha's age.
Sum = 73
Answers
Answer: 20 years old
Step-by-step explanation:
L=Latisha's age. M=Maisha's age.
O=older sister's age. Y=Younger Brother's age
L=M since both Latisha and Maisha are twins.
Y=L-11
O=L+4
L+M+O+Y=73
L+L+L+4+L-11=73
L+L+L+L+4-11=73
4L-7=73
4L=80
L=20 years old

ABC = 40° and
x

Find the length of AC.
Give your answer rounded to 1 DP.
Answers
The length of AC is 6.228 cm.
Here the angle of the triangle ∡ABC is 40°, AB = BC = 9.
We have to find the length of AC which is opposite to ∡B.
Let AB = BC = x , AC = c
From the cosine formula, we know that
[tex]c^{2}[/tex] = [tex]a^{2}[/tex] + [tex]b^{2}[/tex] - 2ab cos α
Here c is the length of the side opposite to the angle α, and a, b is the side adjacent to the angle α.
So from the cosine formula we have
[tex]c^{2}[/tex] = [tex]x^{2}[/tex] + [tex]x^{2}[/tex] -2[tex]x^{2}[/tex]cos α
[tex]c^{2}[/tex] = 2[tex]x^{2}[/tex] - 2[tex]x^{2}[/tex] cos 40°
= 2[tex]x^{2}[/tex](1- cos 40°)
= 2 ×[tex]9^{2}[/tex] ( 1 - 0.76)
= 2 × 81 × 0.24
c = 2 × 9 × 0.2×√3
=3.6 × 1.73
= 6.228cm
Therefore the length of the side AC is 6.228cm.

Answers
Use a second order difference scheme while adhering to the finite difference procedure we discussed in lecture, the rewritten initial value is cos(t)+C.
What is a difference equation?The k initial differences of a sequence or a function are involved in a difference equation of order k, just as the k first derivatives of a function are related in a differential equation of order k.
The two aforementioned relationships enable the transformation of a recurrence relation of order k into a difference equation of order k and, in the other direction, a difference equation of order k into a recurrence relation of order k. Every transformation is the inverse of every other transformation, and the sequences that satisfy the recurrence relation are the exact ones that provide the solution to the difference equation.
Calculations:

If f(a) = 3a – a2, which of the following are not true statements? Select all that apply. f(-5) = -40 f(4) = -4 f(-1) = 2 f(0) = 3 f(3) = 0
Answers
The true statements are f(-5) = -40, f(0) = 3 and f(3) = 0
How to determine the valueGiven the function;
f(a) = 3a – a2
For f(-5), we substitute the value of a as -5, we have
f(-5) = 3(-5) - (-5)²
f(-5) = -15 - 25
f(-5) = -40
For f(4), we have
f(4) = 3(4) = 3(16)
f(4) = 12 - 48
f(4) = -36
For f(-1), we have
f(-1) = 3(-1) - (-1)²
f(-1) = -3 - 1
f(-1) = -4
For f(0), we have
f(0) = 3(0) -(0)
f(0) = 0
For f(3), we have
f(3) = 3(3) - 3²
f(3) = 0

Step-by-step explanation:
the sum of the 3 angles in a triangle = 180° .
consider the inner triangle where
a + b + 58° = 180° ( subtract 58° from both sides )
a + b = 122°
consider the outer triangle where
c + d + 63° = 180° ( subtract 63° from both sides )
c + d = 117°
Then
a + b + c + d = 122° + 117° = 239°

estimate the number of gallons of gasoline consumed by the total of all automobile drivers in the u.s., per year. suppose that there are about 3 × 108 people in the united states, approximately half of the them have cars, each car drives an average of 12,000 mi per year, and consumes a gallon of gasoline for each 20 mi .
Answers
The total amount of gallons of gasoline expended by all the automobile drivers in the United States is 9 × (10)10 gallons. It is obtained using the basic concepts of word problems based on multiplication and division.
What are word problems?
Word problems are defined as mathematical problems that are completely expressed in the notation of words or language rather than numbers. Word problems can simply be based on addition, subtraction, multiplication, division, percentage, etc.
Calculation of the total amount of gasoline consumed in the US in units of gallon
According to the word problem, the total number of people in the US is 3 × (10)8
Number of people having cars = ½ × 3 × (10)8
= 1.5 × (10)8
Each car drives an average of 12000 miles per hour, so the total distance travelled by one car is 12000 miles
The distance covered by all the cars = 1.5 × (10)8 × 12000
= 1.8 × (10)12 miles
20 miles is covered in 1 gallon of gasoline
1 mile is covered in 1/20 gallon of gasoline
So, 1.8 × (10)12 miles will be covered in 1.8 × (10)12 × (1/20)
= 9 × (10)10 gallons
Hence, the gallons of gasoline required is 9 × (10)10 gallons.

HELP PLS.
A line segment has an endpoint at (4, 5). If the
midpoint of the line segment is (-1,4), what is the
location of the line segment's other endpoint?
Answers
=========================================================
Explanation:
A = (4,5) is one endpoint
B = (-1, 4) is the midpoint
C = (x,y) is the other endpoint
For now, focus on the x coordinates of each point
A and C have x coordinates of 4 and x respectively
Add them up and divide in half. Set this equal to the x coordinate of B
(4+x)/2 = -1
4+x = 2*(-1)
4+x = -2
x = -2-4
x = -6 which is the x coordinate of point C
Repeat this same idea for the y coordinates
(5+y)/2 = 4
5+y = 2*4
5+y = 8
y = 8-5
y = 3 which is the y coordinate of point C
Therefore, point C is located at (-6, 3)
--------------------------
To verify the answer, you can use the distance formula to calculate the following segment lengths: AB and BC
You should find that AB = BC. This is because the midpoint splits segment AC into two smaller equal pieces.
Another way to verify the answer is to use the midpoint formula on points A(4,5) and C(-6,3). The result of using this formula should be B(-1,4) mentioned earlier.

Now we can distribute:
21 + 7x - 4x - 4
Now we can combine like terms:

Now we flip them around; the coefficient always should come first:
