[tex]xy \times xy \times xy[/tex]
Find the nth term of this quadratic sequence.
3, 11, 25, 45
Answer:
3 , 11, 25, 45
Diff 8 14 20
Diff 6 6
The second differences are the same. The sequence is quadratic and will contain an n^2 term. The coefficient of n^2 is always half of the second difference. In this example, the second difference is 6. Half of 6 is 3 so the coefficient of n^2 is 3
therefore 3n^2
3 11 25 45
3n^2 3 12 27 48
Remainder 0 -1 -2 -3
Difference -1 -1 -1
linear sequence with nth term -n+1
so nth term of quadratic sequence in 3n^2-n+1

Answer:
1 Binomcdf (10,1/6,3)
Step-by-step explanation:
Tell whether the angles are adjacent or vertical. Then find the value of x.
I finished the angles, but need the value of x.
Answer : The angles are vertical angles and the value of x is [tex]25^o[/tex]
Step-by-step explanation :
Adjacent angles : It is defined as the two angles that have the common arm and common vertex.
Vertical angles : It is defined as the two lines intersect each other and form angles. The opposite angles are known as vertically opposite angles.
And we know that the vertically opposite angles are equal.
In the given image, the angles are vertical angles and vertically opposite angles are equal.
So,
[tex](4x-25)^o=75^o[/tex]
[tex]4x-25^o=75^o[/tex]
[tex]4x=75^o+25^o[/tex]
[tex]4x=100^o[/tex]
[tex]x=\frac{100^o}{4}[/tex]
[tex]x=25^o[/tex]
Therefore, the angles are vertical angles and the value of x is [tex]25^o[/tex]

Use Phythagoras Theorem!!
the length pf a rectangle is 50 cm and its diagonal is 51 cm. work out the area of the rectangle, to the nearest square centimetre.
a² + b² = c²
50² + 51² = c²
2500 + 2601 = c²
5101 = c²
√5101 ≈ 71.42 cm.
Answer: Area of the rectangle = 102.5 cm² Round to 103 cm²
Step-by-step explanation:
The diagonal is the hypotenuse, c So subtract the square on the base (length) to find the altitude (height).
a² + b² = c²
a² + 50² = 51²
a² = 51² - 50²
a² = 2601 -2500
a² = 101 take the square root of both sides
a = √101
a = 10.04987562 Round to 10.05
Area = LW
Area = 50 × 10.05
Area = 102.5 cm² Round to 103 cm²
Please help WHAT IS THE PERCENT OF 39.8 out of 200 QUICK PLEASE
Answer:
19.9%
Step-by-step explanation:
39.8/200 = 0.199 (move decimal two times)
19.9%
or you can just see what number get 200 to 100, which is by dividing by 2. What you do to the bottom you do to the top so 39.8/200 (divide both sides by 2) = 19.9/100
which is 19.9%.

Answer:
C
Step-by-step explanation:
Given
[tex]\frac{2}{3}[/tex] m + 5 = 17 ( subtract 5 from both sides )
[tex]\frac{2}{3}[/tex] m = 12 ( multiply both sides by 3 to clear the fraction )
2m = 36 ( divide both sides by 2 )
m = 18 → C

In your own words, what is the least common multiple of two whole numbers? How can you find it?
Answer:
One way to find the least common multiple of two numbers is to first list the prime factors of each number. Then multiply each factor the greatest number of times it occurs in either number. If the same factor occurs more than once in both numbers, you multiply the factor the greatest number of times it occurs.
Step-by-step explanation:
That's how I do it.

What decimal is equivalent to 4/15
Answer:
0.2667 is the decimal for this
Answer:
0.2bar6
Step-by-step explanation:
The decimal form of 4/15 is 0.2bar6. Divide the numerator by the denominator. 4/15= 0.2666...= 0.2bar(6) In the United States, the repeating decimal is represented with a bar above the repeating decimal.
Find all possible solutions for x and y such that △ABC is congruent to △DEF.
△ABC: sides of length 19, 25, and 3x − 3.
△DEF: sides of length 25, 15, and 5 − y.
△ABC ≅ △DEF when x is ___ and y is ___.
Answer:
Step-by-step explanation:
it means the ABC And DEF have side lengths of 15,19, 25
so 3x-3 = 15
x = 6
5-y = 19
so y = -14

The product of two numbers decreased by six is less than 30. Write an algebraic expression, but do not solve. *
Answer:
(x × y) - 6 < 30
xy - 6 < 30
xy < 30 + 6
xy < 36
Step-by-step explanation:
Let us represent:
First number = x
Second number = y
The product of two numbers decreased by six is less than 30.
The algebraic expression is given as
(x × y) - 6 < 30
xy - 6 < 30
xy < 30 + 6
xy < 36

An airplane begins decreasing its altitude as it approaches the runway. At time t=1, the pilot notes that he has an altitude of 30,000 feet. One minute later, his altitude drops to 29,450 feet. One minute after that, his altitude drops to 28,900 feet. Assuming this pattern continues, write a recursive formula for the altitude of the plane A(t) after t minutes.(1 point)
A(t)=30000+550(t−1)
A(t)=A(t−1)−550 for t>1, where A(1)=30000
A(t)=A(t−1)+550 for t>1, where A(1)=30000
A(t)=30000−550(t−1)
Answer: i think A(t)=30000−550(t−1)

Translate each phrase into an algebraic inequality:
Fiona works part time for a legal firm. She can work a maximum of 30 hours
per week.
Let hours = x
She can work a maximum of 30 hours so x can be any number from 30 or below.
The inequality would be: X <= 30
Answer:
Let the maximum time be x
She can work 30 hrs or below ( maximum of 30 hrs)
Therefore, the equation is
[tex] \huge \boxed{x \leqslant 30 \: hours}[/tex]
