See also Tangent to a circle). In any right triangle, the tangent of an angle is the length of the opposite side (O) divided by the length of the adjacent side (A). ... In a formula, it is written simply as 'tan'.

Answer:

1. m<2 = 115 °

2. m<5 = 83 °

3. m<8 = 45 °

4. m<4 = 137 °

Step-by-step explanation:

1. Determination of m<2

m<1 = 115 °

m<2 =?

m<2 = m<1 (vertically opposite angles are equal)

m<2 = m<1

m<2 = 115 °

2. Determination of m<5

m<6 = 83 °

m<5 =?

m<5 = m<6 (vertically opposite angles are equal)

m<5 = m<6

m<5 = 83 °

3. Determination of m<8

m<9 = 45 °

m<8 =?

m<8 = m<9 (vertically opposite angles are equal)

m<8 = m<9

m<8 = 45 °

4. Determination of m<4

m<3 = 137 °

m<4 =?

m<4 = m<3 (vertically opposite angles are equal)

m<4 = m<3

m<4 = 137 °

goldfiish [28.3K]

Answer: No, the normal curve cannot be used.

Step-by-step explanation:

The theorem of the Normal approximation states that if X is B(n,p) then for large n X is N(np, np(1-p)).

The accuracy of this approximation is good

i. for n > [10/p(1-p)]

ii. p is close to 1/2

Hence given p= 4% = 0.04,

q = 1 - 0.04 = 0.96

Let N = [10/p(1-p)]

We find N = 10/p(1-p) = 10/(0.04× 0.96)

N ~= 260

Since n < 260 and p < 0.5

The approximation is not a good one

Answer:

See picture attached

Step-by-step explanation:

The graph of a non-proportional linear relationship is a line that does not cross through the origin. The graph of a proportional linear relationship does.

Given the general expression of a line: y = ax + b, where a and b are constants, if b is equal to zero, the line cross through the origin, otherwise the line inercept y-axis at value of b.

Direct variation means that y = kx, where k is a constant, then is a proportional linear relationship.

Given a cell phone company charges $19.95 per month for the first 2G, then $5 per gig over the initial 2G; the graph is a non-proportional linear relationship because the cost is never zero and the graph  does not cross through the origin.

Given a cell phone company charges $29.95 per month always, then the cost is never zero and the graph  does not cross through the origin.

How can you determine the domain and range of function.
Mice21 [21]

Answer:

The domain of a function is the complete set of possible values of the independent variable.

In plain English, this definition means:

The domain is the set of all possible x-values which will make the function "work", and will output real y-values.

When finding the domain, remember:

The denominator (bottom) of a fraction cannot be zero

The number under a square root sign must be positive in this section
