Answer:
a₂₀ = 69
Step-by-step explanation:
The nth term of an arithmetic sequence is
[tex]a_{n}[/tex] = a₁ + (n - 1)d
where a₁ is the first term and d the common difference
Here a₁ = 12 and d = 15 - 12 = 3 , then
a₂₀ = 12 + (3 × 19) = 12 + 57 = 69
anyone good with this problem! pls help , due in 16.
How do I factor the polynomial -7y+y^2-30? I can do it in standard form but now im confused. Please help.
Answer:
your answer would be
(y - 10) (y + 3)
hope this helps
Answer:
Step-by-step explanation:
-7y+y^2-30 is presented legally, but not logically I will re-write it better
just re-write in standard form
y^2 - 7y - 30
y² - 7y - 30 is it better now?
(y - 10) (y + 3)

What is fraction?An element of a whole is a fraction. The number is represented mathematically as a quotient, where the numerator and denominator are split. Both are integers in a simple fraction. A fraction appears in the numerator or denominator of a complex fraction. The numerator of a proper fraction is less than the denominator.
Given:
It takes an old printer 8 hours to print all the pictures for the yearbook.
A modern printer can do the same job in 5 hours.
If both work together,
it will take,
x(1/8 + 1/5) = 1
x(8 + 5)/40 = 1
8x + 5x = 40
x = 40/13
x = 3.07
x = approximately 3.1 hours.
Therefore, the work will be done in 40/13 hours.

The sides of a polygon are 3cm, 5cm, 6cm, 8cm and 10cm. The perimeter of a second similar polygon is 48cm. What is the length of the longest side of the second polygon?
Answer:
Length of the longest side of the similar polygon = 15 cm
Step-by-step explanation:
Sides of a polygon are 3 cm, 5 cm, 6 cm, 8 cm and 10 cm
Perimeter of the polygon = 3 + 5 + 6 + 8 + 10
= 32 cm
Perimeter of the similar polygon = 48 cm
Since, scale factor = [tex]\frac{\text{Perimeter of the similar polygon}}{\text{Perimeter of the original polygon}}[/tex]
= [tex]\frac{48}{32}[/tex]
= 1.5
Since, scale factor = [tex]\frac{\text{Dimension of the similar polygon}}{\text{Dimension of the original polygon}}[/tex]
1.5 = [tex]\frac{\text{Dimension of the similar polygon}}{10}[/tex]
Dimension of the similar polygon = 1.5 × 10
= 15 cm
Therefore, longest side of the similar polygon = 15 cm

(1/2)^x=16^2
Could you please help me with the step-by step? This problem is giving me trouble.
Write both sides as powers of 2. First,
1/2 = 2⁻¹
16 = 2⁴
so the equation can be rewritten as
(1/2)ˣ = 16²
(2⁻¹)ˣ = (2⁴)²
Recall that [tex](a^b)^c=a^{bc}[/tex], so that
2⁻ˣ = 2⁸
The bases are the same, so the exponents must be equal:
-x = 8
x = -8
Use completing the square to rewrite the given function in vertex form. Determine whether the vertex is a maximum or minimum
value. Select the TWO correct answers.
y = x2 + 4x - 10
-
A)
The vertex form is y = (x - 6)2 + 2.
B)
The vertex form is y= 4x + 2)2 - 10.
C)
The vertex form is y = -(x - 2)2 - 6.
D)
The vertex is a minimum value at point (-6,2).
E)
The vertex is a maximum value at point (2.-6).
Answer:
Step-by-step explanation:
The equation as written doesn’t work. Are you sure it is y = x² + 4x - 10, and not
y = -x² + 4x - 10 ?
y = -(x² - 4x) - 10
y = -(x² - 4x + 2²) + 2² - 10
y = -(x-2)² - 6
the vertex is a maximum at (2,-6)

How many degrees is arc PQ?
Answer:
Step-by-step explanation:
Arc PQ is 60°
Answer:
[tex]\boxed {\boxed {\sf Arc \ { PQ } = \ 60 \ degrees}}[/tex]
Step-by-step explanation:
The angle that forms arc PQ is a central angle, because the angle's vertex is at the center of the circle.
According to arc-angle relationships, the measure of a central angle is equal to the arc.
Since the central angle is equal to 60 degrees, arc PQ is also equal to 60 degrees.

The field has the shape of a trapezoid. Its area can be found using the formula for the area of a trapezoid:
A = (1/2)(b1 +b2)h
A = (1/2)(399 +594)(506) = 251,229 . . . . . . acres
__
At 38909 plants per acre, the number of plants that should be planted for maximum yield is ...
(251,229 ac)(38,909 plants/ac) = 9,775,069,161 plants
_____
Comment on units
The problem statement tells us "each unit of coordinate plane represents one acre." An acre is a unit of area, so we have to assume this means that each square unit represents one acre. That means each unit on each axis is about 208.71 feet, the dimension that would have to be squared to get an area of one acre--43,560 square feet.
