Answer:

The exact value should be

[tex] \sqrt{3} [/tex]

Step-by-step explanation:

Though you can get this directly out from your calculator, but you can utilize the opposite angle identities, cot(-

θ)=-cot θ, then use the trig identity, which is

[tex] \cot(θ) = \frac{ \cos(θ) }{ \sin(θ) } [/tex]

So cot (-330)=cos (-330)/sin (-330)

Step-by-step explanation:

When multiplying fractions, you do not need a common denominator, and the entire fraction gets multiplied across, however when adding or subtracting fractions, you must have a common denominator, and then only compute the numerator, as the bases are already the same

Answer:

A is the midpoint

Step-by-step explanation:

Given

A(5.2) B(6,-3) and C(4.7)

Required

Which is the midpoint

Midpoint is calculated using:

[tex](x,y) = \frac{1}{2}(x_1+x_2,y_1+y_2)[/tex]

Testing A as the midpoint, we have:

[tex](5,2) = \frac{1}{2}(6+4,-3+7)[/tex]

[tex](5,2) = \frac{1}{2}(10,4)[/tex]

[tex](5,2) = (\frac{1}{2}*10,\frac{1}{2}*4)[/tex]

[tex](5,2) = (5,2)[/tex]

The above equation is true. Hence, A is the midpoint of B and C

Answer:

Amount of water needed for 10 serving = 7.5 cup

Step-by-step explanation:

Given:

1 serving needed water = 3/4 cup

Find:

Amount of water needed for 10 serving

Computation:

Amount of water needed for 10 serving = 10[3/4]

Amount of water needed for 10 serving = 7.5 cup

Answer: 49

Step-by-step explanation: In order to complete the square, you need a perfect square trinomial on the left side of the equation.

The question is, what is the number we need?

Well it comes from a formula. The number that is added to both sides

comes from half the coefficient of the middle term squared.

So that's half of 14 which is 7, squared which is 49.

Answer: 19

Step-by-step explanation:

[tex]f(4)=(4)^2+3=16+3=19[/tex]

Answer:

f(4) = 19

Step-by-step explanation:

f(x) = x^2 + 3

plug in 4 for the xs

f(4) = 4^2 + 3

f(4) = 16 + 3

f(4) = 19

Answer:

x = 23

Step-by-step explanation:

For this figure, we know we are dealing with a 90 degree angle since there is a small square in the figure, therefore we can set up the equation...

65 + (x + 2) = 90

In this sense, the parenthesis are unnecessary.

67  + x = 90

-67         -67

x = 23

Hope this helps!

Answer:

See explanation below

Step-by-step explanation:

The degree of a polynomial is the LARGEST power at which the variable/s appear in their expression.

Notice that in the given polynomial, the highest power for the variable x is 3, from the term 5 x^3.

There is no other term with higher power for x.

The variable appear in the expression [tex]3^{4} + 5x^{3} + 7x^{2} + 3x[/tex] x which has highest power 3 not 4 .

We have to explain,  why the polynomial [tex]3^{4} + 5x^{3} + 7x^{2} + 3x[/tex] has a degree 3 and not 4.

According to the question,

A polynomial's degree is the highest or the greatest power of a variable in a polynomial equation.

The degree of a polynomial is the largest power at which the variable appear in their expression.

[tex]Polynomial = 3^{4} + 5x^{3} + 7x^{2} + 3x[/tex]

The given polynomial, the highest power for the variable x is 3, from 5 .

Hence, The variable appear in the expression [tex]3^{4} + 5x^{3} + 7x^{2} + 3x[/tex] x which has highest power 3 not 4 .
