Answer:

30 in

Step-by-step explanation:

See attached image.

The length of AB is 17 (radius).  The length of AC is 8 (given info).

AC splits segment BD in half, so point C is the midpoint of segment BD.

AC is perpendicular to the chord, so triangle ABC is a right triangle.  You now have a right triangle with a leg of length 8 and hypotenuse of lenght 17.

The Pythagorean Theorem:  (leg)^2 + (leg)^2 = (hypotenuse)^2.

[tex]8^2+(BC)^2=17^2\\\\64+(BC)^2=289\\\\(BC)^2=225\\\\BC=\sqrt{225}=15[/tex]

That's half the length of the chord, so double that to get 30 inches for the full length of the chord BD.

Answer:

Dimension of the enclosure is 56.56 ft * 14.14 ft

Step-by-step explanation:

Given -

Let us suppose that x is the length of steel fence and y is the length of one side of pine boards

We know that - xy = 800.

y = 800/x

Let us say that  C is the cost of fence

                = 3x + 6(2y) = 3x + 12y = 3x + 12(800/x)

C = 3x + 9600x-1, x > 0

C' = 3 - 9600x-2 = (3x2-9600)/x2

C' = 0 when 3x2 = 9600

                  x2 = 3200

                  x = √3200 ft ≈ 56.56 ft

So, the cost is minimized when x ≈ 56.56 ft and y = 800/x ≈ 14.14 ft

Answer:

B

Step-by-step explanation:

(5-2)/(x-1) = 3

x=-2

Answer:

D. 0

Step-by-step explanation:

the slope of the line is negative reciprocal to the slope of the other line 1/3=> -3

(5 - 2)/(x - 1) = -3

=> 3/(x - 1) = -3

=> x - 1 = -1

=> x = 0

Answer:

ffrank =6.3456

Step-by-step explanation:

Answer:

1. F(-5) = -9

2. F(-4) = -7

3. F(1) = 3

4. F(3) = 7

5. F(5) = 11

Step-by-step explanation:

For each problem, F(x) is replaced with x.

An example is F(-5) = 2x + 1 (your first question).

To solve this, you replace x with -5.

This creates F(-5) = 2(-5) +1

We just simplify by multiplying -5 by 2 and then adding 1.

-5 times 2 equals -10. -10 plus 1 equals -9.

Your final answer for this example problem would be F(-5) = -9.

This applies to all problems as such -- F(x) where x inside the parentheses replaces all x values in the equation.

Answer:

See Explanation

Step-by-step explanation:

Given

Luanne

[tex]Salt = 3\ cups[/tex]

[tex]Gallon = 1[/tex]

Fiona

[tex]Salt = 2\ cups[/tex]

[tex]Gallon = 3[/tex]

The question is incomplete, as the options are not given.

However, possible comparison that can be made are

(a) The unit amount of salt

(b) Whose solution is more concentrated with salt

(a) The unit amount of salt

To do this, we divide the amount of salt by the number of gallons.

[tex]Unit = \frac{Salt}{Gallon}[/tex]

For Luanne

[tex]Unit = \frac{3}{1}[/tex]

[tex]Unit = 3 cups/gallon[/tex]

For Fiona

[tex]Unit = \frac{2}{3}[/tex]

[tex]Unit = 0.67cups/gallon[/tex]

(b) Whose solution is more concentrated with salt

By comparing the result in (a)

We have:

[tex]Unit = 3 cups/gallon[/tex] --- Luanne

[tex]Unit = 0.67cups/gallon[/tex] --- Fiona

Luanne unit amount implies that there are 3 cups in every gallon of water;

Fiona unit amount implies that there are 0.67 cups in every gallon of water;

[tex]3 >0.67[/tex]

Hence, Luanne solution is more concentrated with salt

Answer:

D is the equivalent expression

Answer:

Step-by-step explanation:

Given formula:    y= -4x^2+24x+2

max height given by the derivative of above formula,  being equal to zero

0 = -8t +24

8t = 24

t = 3

at 3.0000000 seconds there will be a max in the rockets height ( that was nice of who ever figured out this formula to make it so easy )

y = height

y= -4*3^2+24*3+2

h = -36 +72 +2

h = 38  feet?   we were not told if the formula is in feet.  ( assume that it is , but double check it)

Answer:

Step-by-step explanation:

The n th term of a geometric sequence is

= a

where a is the first term and r the common ratio

Both a and r have to be found

Given a₃ = - 2, then

ar² = - 2 → (1)

Given a₇ = - 32, then

a = - 32 → (2)

Divide (2) by (1)

= , that is

= 16 ( take the fourth root of both sides )

r = 2 ← common ratio

Substitute r = 2 into (1)

a × 2² = - 2, that is

4a = - 2 ( divide both sides by 4 )

a = -  ← first term

Hence

= -  ← explicit formula

and

= -  ×  = - 0.5 × 512 = - 256

Answer:

42 ft

Step-by-step explanation:

body = x

tail = 7x

x + 7x = 48

8x = 48

Divide both sides by 8

x = 6

Tail

7x = 7(6)

7x = 42

Answer:

her mother drives 142 miles more than her brother.

Step-by-step explanation:

227 + 337 = 564 miles in total driven

¼ of 564 miles = 136 miles (what her brother drives of the 564 miles)

564 - 136 = 428 left

her mother drives 428-150 miles from Wednesday = 278

278-136=142

Answer: 2 ounce

Step-by-step explanation:

Given

16 ounce of the box is shared by Sue and Bill

Sue has eaten [tex]\frac{5}{8}[/tex] of the box

Bill has eaten [tex]\frac{1}{4}[/tex] of the box

total cereal eaten by them is

[tex]\Rightarrow \dfrac{5}{8}+\dfrac{1}{4}=\dfrac{5}{8}+\dfrac{2}{8}\\\\\Rightarrow \dfrac{7}{8}[/tex]

So, they have eaten this much of the box. Amount left in the box is

[tex]\Rightarrow 1-\dfrac{7}{8}\\\\\Rightarrow \dfrac{1}{8}[/tex]

In ounce it is

[tex]\Rightarrow 16\times \dfrac{1}{8}\\\\\Rightarrow 2\ \text{ounce}[/tex]
