Answer 1

The nth term of a sequence exists 2n2² - 4n+4 is 36.

What is PEMDAS' order of operations?

The order of operations exists as a rule that describes the right sequence of measures for estimating a math expression. We can recognize the order utilizing PEMDAS: Parentheses, Exponents, Multiplication, and Division (from left to right), Addition, and Subtraction (from left to right).

[tex]$2*8*2^{2} - 4*8+4[/tex]

Follow the PEMDAS order of operations

Calculating the exponents, we get 2² = 4

[tex]= 2*8*4 - 4*8+4[/tex]

= 64-32 +4

= 36

Therefore, the nth term of a sequence that exists 2n2² - 4n+4 is 36.

A rectangle has a length of 2y inches and a width of y - 4 inches. If the perimeter of the rectangle is 22 inches, what is y? What is the length? What is the width?

Answers

P = 2( l + w)
Length: 2y
Width: y - 4
P= 22 inches
2(2y) + 2(y - 4) = 22
4y + 2y - 8 = 22
4y + 2y = 6y and add (-8) on both sides of the equation to equal: 6y = 30
Divide 6 from both sides of the equation and you get: y = 5
Check:
4(5) + 2(5) - 8 = 22
20 + 10 - 8 = 22
30 - 8 = 22 ✅

Apples are on sale at the local fruit stand at 4 lbs. for $2.60. Which equation can be used to find the cost, c, of n pounds of apples?
c = 4
c = .65n
c = 2.60n
c = 8n

Answers

Answer:

B ) c = 0.65n

Step-by-step explanation:

To find how much a single pound costs, divide the total cost by the total weight (2.60 ÷ 4). So, the cost (c), equals $0.65 per pound.

2.60/4=0.65n
So, I think the answer is c=0.65n

Step-by-step explanation:

Given data

One time fee= $10.25

let the number of times visited be x

and the total cost for x visits be y

Hence

y=10.25+5x------------1

for y=135.25

let us find x

135.25= 10.25+5x

135.25-10.25= 5x

What are the coordinates of the endpoints of segment M'N'? M'(-6, 9) and N'(4, 9) M'(-6, 9) and N'(3, 9) M'(-2, 3) and N'(7, 9) M'(-2, 3) and N'(1, 3)

Answers

Answer:

The answer is B. M'(-6,9) and N'(3,9)

Step-by-step explanation:

To find the coordinates of the endpoints of segment M'N' you'll have to use the rule through which it was dilated.

M(-4,6) after the rule it will be (-4*1.5, 6*1.5) = M'(-6,9)

N(2,6) after the rule it will be (2*1.5, 6*15) = N'(3,9)

The answer is B. M'(-6,9) and N'(3,9)

Hope this helps :)

The required endpoint of the segment M'N' is given as M'(-6,9) and N'(3,9) respectively. Option B is correct.

What is coordinate?

Coordinate, is represented as the values on the x-axis and y-axis of the graph. while the coordinate x is called abscissa and the coordinate of the y is called ordinate.

Here,
The equation for the dilation is given as,
= {1.5x, 1.45y}

Now,
Put coordinates of M and N in the above equation,
Coordinate of M' = (-4×1.5, 6×1.5) = M'(-6,9)

Similarly, the coordinate of N',
Coordinate of N' = (2×1.5, 6×1.5) = N'(3,9)

Thus, the required endpoint of the segment M'N' is given as M'(-6,9) and N'(3,9) respectively. Option B is correct.

Find the square root. 1/16​

Answers

Answer:

The square root of 1/16 is 1/4=0.25

Step-by-step explanation:

The square root of 1/16 is 1/4.

To find the square root of 1/16, you can take the square root of the numerator and the denominator separately.

√(1/16) = √1 / √16

Since the square root of 1 is 1, and the square root of 16 is 4:

√(1/16) = 1/4

So, the square root of 1/16 is 1/4.
