Answer 1

Answer:

I am awesome at these!!

Step-by-step explanation:

Only the last one is a function. This is because there are no repeating x values, which are the first numbers. It is okay for there to be repeating y values, but not x.

A wire that is 80 centimeters long is shown below. The wire is cut into two pieces, and each piece is bent and formed into the shape of a square. 80 cm wire Suppose that the side length (in centimeters) of one square is x cm. Express the perimeter of the big square in terms of x. (1 point)

Answers

Answer:

The perimeter of the second(big) square = [tex]\mathbf{4 \times \begin {pmatrix} \dfrac{80-x}{4} \end {pmatrix}}[/tex]

Step-by-step explanation:

From the information given:

The length of the piece of the wire  = 80 cm

When being cut into two pieces;

the length of the first wire = x

Then the length of the second(big) wire will be = 80 - x

However, when each piece is bent to a square shape

The length of one side of the first square = [tex]\dfrac{x}{4}[/tex]

The length of one side of the second(big) square; [tex]\dfrac{80-x}{4}[/tex]

Area of a square = l² ( where l is the length of the sides)

For the first square

A₁ = [tex](\dfrac{x}{4})^2[/tex]

A₁ = [tex]\dfrac{x^2}{16}[/tex]

The area of the second(big) square is:

A₂ = [tex](\dfrac{80-x}{4})^2[/tex]

A₂ = [tex](\dfrac{(80-x)^2}{4})[/tex]

The perimeter of the first square = [tex]4 \times \dfrac{x}{4}[/tex]

The perimeter of the second(big) square = [tex]\mathbf{4 \times \begin {pmatrix} \dfrac{80-x}{4} \end {pmatrix}}[/tex]

A golf ball is hit with an initial velocity of 80 feet per second. H= -16t^2 + 80t.
1) When will the ball reach 48ft?
2) When will the ball reach 110ft?

Answers

9514 1404 393

Answer:

t = 0.697 secondsnever (the maximum height is 100 ft)

Step-by-step explanation:

A graphing calculator provides a nice solution to this question.

__

1) Put 48 ft in for H and solve for t:

  48 = -16t^2 +80t

  -3 = t^2 -5t

  3.25 = t^2 -5t +6.25 = (t -2.5)^2

  t = 2.5 ±√3.25

The ball will first reach 48 feet at t = 2.5 -√3.25 ≈ 0.697224 seconds.

__

2) The equation tells us the maximum height occurs at t=2.5 seconds. That height is ...

  H = -16(2.5^2) +80(2.5) = 100

The maximum height is 100 feet. The ball will never reach 110 feet.

That's

the rectangle had a length that is 6 inches less that twice it's width. If the perimeter is 54, find the dimensions of the rectangle​

Answers

Answer:

11" x 16"

Step-by-step explanation:

This problem can be solved with an equation

If you translate the first words into an equation, you get:

l = 2w - 6

(where w is width and l is length)

The perimeter (p) of any rectangle is 2l + 2w, so

if p = 54

then 54 = 2l + 2w

Now, you have the following two equations:

l = 2w - 6

2l + 2w = 54

In order to solve this for w, you can replace the l in the equation with (2w - 6) because of the substitution property of equality (if a = b, then a can be replaced with b at any time), so you get:

54 = 2(2w - 6) + 2w

Now, you simplify:

54 = 2(2w - 6) + 2w

= 54 = 4w - 12 + 2w

= 54 = 6w - 12

= 66 = 6w

= w = 11

So the width is 11. In order to find the length you just need to substitute it into the equation for the perimeter:

2l + 2(11) = 54

= 2l + 22 = 54

= 2l = 32

= l = 16

In conclusion, the width is 11 and the length is 16.

Answer:

Step-by-step explanation:

A sequence can be generated by using an=an−1+9, where a1=−5 and n is a whole number greater than 1. What are the first four terms in the sequence?

A.−5, 4, 13, 22

B.9, 4, −1, −6

C.−5, −45, −405, −3645

D. 9, −45, 225, −1125

From the above question,

A sequence can be generated by using an=a(n−1)+9, where a1=−5

The formula = an = a1 + (n - 1)d

a1 = First term

d = common difference = 9

We are to find the first 5 terms

First term = a1 =

an=an−1+9, where a1=−5

The formula =

a1 = -5 (1 - 1) + 9

= -5(0) 9

= -9

Second term = a2 =

an=an−1+9, where a1=−5

The formula = an = a1 (n - 1) + d

a2 = -5(2 - 1) + 9

= -5(1)+ 9

= -5 + 9

= 4

Third term = a3 =

an=an−1+9, where a1=−5

The formula = an = a1(n - 1) + d

a3 = -5(3 - 1)9

= -5(2) + 9

= -10+ 9

= -1

Fourth term = a2 =

an=an−1+9, where a1=−5

The formula = an = a1(n - 1) + d

a4 = -5(4 - 1)9

= -5(3) +9

= -15 +9

= -6

Answers

Answer:

C

Step-by-step explanation:

Calculate the slope m using the slope formula, then equate to [tex]\frac{1}{4}[/tex]

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = (3, r) and (x₂, y₂ ) = (7, 2)

m = [tex]\frac{2-r}{7-3}[/tex] = [tex]\frac{2-r}{4}[/tex] , then

[tex]\frac{2-r}{4}[/tex] = [tex]\frac{1}{4}[/tex] ( since denominators are both 4, equate the numerators )

2 - r = 1 ( subtract 2 from both sides )

- r = - 1 ( multiply both sides by - 1 )

r = 1 → C
