Answer:

1 would be 1320

3 would be 3960

4 would be 5280

Step-by-step explanation:

The cost of 1, 3 and 4 ounces of gold in 2016 was $1,320, $3,960 and $5,280 respectively.

Cost of 2 ounces of gold in 2016 = $2,640

Cost of 1 ounce of gold in 2016 = Cost of 2 ounces of gold in 2016 ÷ 2

= $2,640 ÷ 2

= $1,320

Cost of 3 ounces of gold in 2016 = Cost of 1 ounce of gold in 2016 × 3

= $1,320 × 3

= $3,960

Cost of 4 ounces of gold in 2016 = Cost of 1 ounce of gold in 2016 × 4

= $1320 × 4

= $5,280

Therefore, the cost of 1, 3 and 4 ounces of gold in 2016 are $1,320, $3,960 and $5,280 respectively.

Answer:

The diamond production is 2006 is expected to be 13.24 billion

Step-by-step explanation:

Here, we want to predict the diamond production is 2006

The equation to use is given in the question as;

f(x) = 0.39x + 10.9

Since x is the number of years after 2006, in this particular question, x will be 2006-2000 = 6

So f(6) = 0.39(6) + 10.9

f(6) = 2.34 + 10.9

f(6) = 13.24 billion

Answer:

c(10)=40

c(15)=52.5

Step-by-step explanation:

c(10) means you plug 10 into your x same with (c15) you plug in 15 so for c(10) it would be 2.5(10) + 15 which is 40

The value of c(10) and c(15) is 40 and 65 respectively.

The given function is c(x) = 2.5x + 15.

A function is defined as a relation between a set of inputs having one output each. In simple words, a function is a relationship between inputs where each input is related to exactly one output. Every function has a domain and codomain or range. A function is generally denoted by f(x) where x is the input.

Now, c(10)=2.5(10)+15=40

c(15)=2.5(15)+15=52.5

Given c(20) = 65

So, 65=2.5x+15

⇒50=2.5x

⇒x=20

Therefore, the value of c(10) and c(15) is 40 and 65 respectively.

Answer:

Additional bags required = 4

Step-by-step explanation:

Marianne buys number of bags of potting soil = 16

Each bag weighs = [tex]\frac{3}{4}[/tex] pounds

Total weight of 16 soil bags = [tex]16\times \frac{3}{4}=12[/tex] pounds

If Marianne's father requires potting soil = 15 pounds

Amount of additional soil he will require = 15 - 12

                                                                   = 3 pounds

Therefore, number of additional soil bags required = [tex]\frac{\text{Weight of soil required}}{\text{Soil in each bag}}[/tex]

                                                                                     = [tex]\frac{3}{\frac{3}{4}}[/tex]

                                                                                     = [tex]3\times \frac{4}{3}[/tex]

                                                                                     = 4 bags

Additional bags required by Marianne= 4

Step-by-step explanation:

Answer:

y = 1/8 (5 sqrt(x^2) - 3 x) or y = 1/8 (-3 x - 5 sqrt(x^2))

Step-by-step explanation:

Solve for y:

-4 y^2 - 3 x y + x^2 = 0

Hint: | Multiply both sides by a term to make the coefficient of y^2 positive.

Multiply both sides by -1:

4 y^2 + 3 x y - x^2 = 0

Hint: | Using the quadratic formula, solve for y.

y = (-3 x ± 5 sqrt(x^2))/8:

Answer: y = 1/8 (5 sqrt(x^2) - 3 x) or y = 1/8 (-3 x - 5 sqrt(x^2))

Answer:

sin2x = [tex]\frac{30}{34}[/tex]

Step-by-step explanation:

Given

tanx = [tex]\frac{3}{5}[/tex] = [tex]\frac{opposite}{adjacent}[/tex]

This is a right triangle with legs 3 and 5

Let the hypotenuse be h , then using Pythagoras' identity

h² = 3² + 5² = 9 + 25 = 34 ( take the square root of both sides )

h = [tex]\sqrt{34}[/tex]

Thus

sinx = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{3}{\sqrt{34} }[/tex]

cosx = [tex]\frac{adjacent}{hypotenuse}[/tex] = [tex]\frac{5}{\sqrt{34} }[/tex]

Hence

sin2x = 2sinxcosx = 2 × [tex]\frac{3}{\sqrt{34} }[/tex] × [tex]\frac{5}{\sqrt{34} }[/tex] = [tex]\frac{2(3)(5)}{\sqrt{34}(\sqrt{34}) }[/tex] = [tex]\frac{30}{34}[/tex]

Answer:

A) 3w(w-7)

Step-by-step explanation:

[tex]\frac{w-5}{w-7} and \frac{w+8}{3w}[/tex]

w-7 is a binomial, and 3w is a monomial. Because you cannot put one denominator into the other or multiply both denominators by a number when you have this type of difference where multiplying by a number won't get you the same result, you must multiply them each other.

Therefore:

3w(w-7) would be your LCD.

Answer:

Step-by-step explanation:

Fractions

We observe that the fractions can't be simplified any more and they are in the simplest form

Next, the denominators w - 7 and 3w don't have common factors

Therefore the common denominator is the product of denominators:

Correct option is A

Answer: There are 16 quarters and 10 dimes.

Step-by-step explanation:

Let x = Number of quarters

y= Number of dimes.

As per given,

x+y = 26  (i)

x= y+6  (ii), substitute this in (i), we get

y+6+y= 26

⇒2y+6=26

⇒ 2y = 26-6=20

⇒ 2y =20

⇒ y =10   [Divide both sides by 2]

Put this in (ii),  x= 10+6 =16

So there are 16 quarters and 10 dimes such that 16 (0.25)+10(0.10)= $5 .
