Answer:

(f•g)(x) = 3x^2 -1/3

Step-by-step explanation:

The solid dot in (f•g)(x) is assumed to mean you want the product of the functions, not their composition. So, ...

(f•g)(x) = f(x)•g(x) = (x -1/3)(3x +1) = x(3x +1) -1/3(3x +1) = 3x^2 +x -x -1/3

(f•g)(x) = 3x^2 -1/3

Angle O=64

Side m=7.3159882(rounded if needed)

Side n=16.68902(round if needed)

We are given

Angle M which equal 26.

Angle N equals 90 degrees

Side MN which equal 15.

We are asked to find all the missing elements of the triangle.

Angle O can be found using triangle interior theorem so we can add 90+26+x =180 to find the value that satisfies the x value.

$90 + 26 + x = 180$

$116 + x = 180$

$x = 64$

Angle O=64 degrees

We can find side m by doing law of sines.

$\frac{on}{ \sin(26) } = \frac{mn}{ \sin(64) }$

$\frac{on}{ \sin(26) } = \frac{15}{ \sin(64) }$

$on = \frac{15}{ \sin(64) } \times \sin(26)$

which is 7.315(round if neeeded).

We can find side n using pythagorean theorem,

${15}^{2} + {7.3}^{2} = {n}^{2}$

$225 + 53.29 = {n}^{2}$

$\sqrt{278.29}$

Side n=16.689(round if needed)

Answer:

3/8 cups.

Step-by-step explanation:

2 tablespoons of sugar = 1/16 * 2 = 1/8 cup of sugar.

1/2 cup = 4/8 cups.

So the extra sugar required = 4/8 - 1/8

= 3/8 cups.

Allisa [31]

To find the answer divide each money amount by the cost:
3.45/14=<span>0.246428571429
</span>4.35/16=0.271875
3.29/12=0.274166666667
4.25/15=<span>0.283333333333
</span>The pickle jar that has the best deal is 14 oz for $3.45

Hope this helps!
