Answer:

The last package having 18 ounce beans in $6.30 is best to buy.

Step-by-step explanation:

Given that:

A 7​-ounce package costs ​$2.52

for 1 ounce it will cost = $2.52/7

1 ounce will cost = $0.36

A 15​-ounce package costs ​$5.55

for 1 ounce it will cost = $5.55/15

1 ounce will cost = $0.37

An 18​-ounce package costs ​$6.30.

for 1 ounce it will cost = $6.30/18

1 ounce will cost = $0.35

So the last package having 18 ounce beans in $6.30 is best to buy.

i hope it will help you!

Answer: 49/60

Step-by-step explanation:

(1/3+2/5)-1/4-(5/6-7/6)

Primero  (5/6-7/6)

5/6-7/6=-2/6

1/3+2/5-1/4-(-2/6)

1/3+2/5-1/4+2/6

2/6=1/3

1/3+2/5-1/4+1/3

2/3+2/5-1/4

2/3=10/15

2/5=6/15

10/15+6/15-1/4

16/15-1/4

16/15=64/60

1/4=15/60

64/60-15/60=49/60

Can you help me create a polynomial function matching the criteria on the left please and thanks
Olenka [21]

Answer:

f(x) = \dfrac{1}{8}(x + 4)^2(x + 1)(x - 3)

Step-by-step explanation:

From inspection of the graph, we can see that the curve intercepts the x-axis at (-4, 0), (-1, 0) and (3, 0)

Therefore,

x = -4 ⇒ x + 4 = 0

x = -1 ⇒ x + 1 = 0

x = 3 ⇒ x - 3 = 0

Because (-4, 0) touches the x-axis, then (x + 4)² will be a factor

So (x + 4)², (x + 1) and (x - 3) are all factors of the polynomial

\implies f(x) = \dfrac{1}{n}(x + 4)^2(x + 1)(x - 3)

If we multiply the constants, this will give us the y-intercept:

⇒ 4² x 1 x -3 = -48

From inspection of the graph, the y-intercept is -6

So to get from -48 to -6 we need to multiply -48 by 1/8

Therefore, n = 1/8

\implies f(x) = \dfrac{1}{8}(x + 4)^2(x + 1)(x - 3)

Which function has a simplified base of 4RootIndex 3 StartRoot 4 EndRoot? f(x) = 2(RootIndex 3 StartRoot 16 EndRoot) Superscript
PIT_PIT [208]

Answer:

  f(x)=4\sqrt[3]{16}^{2x}

Step-by-step explanation:

We believe you're wanting to find a function with an equivalent base of ...

  4\sqrt[3]{4}\approx 6.3496

The functions you're looking at seem to be ...

  f(x)=2\sqrt[3]{16}^x\approx 2\cdot2.5198^x\\\\f(x)=2\sqrt[3]{64}^x=2\cdot 4^x\\\\f(x)=4\sqrt[3]{16}^{2x}\approx 4\cdot 6.3496^x\ \leftarrow\text{ this one}\\\\f(x)=4\sqrt[3]{64}^{2x}=4\cdot 16^x

The third choice seems to be the one you're looking for.
