Step-by-step explanation:

oh law of sines   soo  sin(A) / a = Sin(B) / b

2a)

here DE = side f   then let's find that side with law of sines and plug side f in as 'a' in law of sines , so

Sin(28) / a = Sin(54) / 31  ( where a = f = DE )

can you do the algebra here Emily?  or do you want me to show that?

Sin(28) *31 / Sin(54) = a

17.989 =a

18.0 =a       (rounded to nearest 10th)

DE = 18.0 m

2b)

find RT  where RT = side a

since they give use 2 of the other sides of the triangle we can quickly figure out the S angle.   180 = 71+62+S   so  S = 47°  ( I'm going kinda fast b/c I don't know how much time you have  :? )

then Sin(A) /a = Sin(B) / b

Sin(47) / a = Sin(62) / 29

Sin(47) *29 / Sin(62) = a

24.020 = a

RT = 24.0 meters  ( rounded to nearest 10th )

2c)

they want us to find ∠X with law of sines soo

I'll just use the letter they give us for variables

Sin(X) / x  = Sin(Y ) / y

Sin(X) = x* Sin(y) / y

X = arcSin [ 14 * Sin(108) / 34 ]

X = arcSin [ 0.3916115]

X = 23.0548°

X= 23°  ( rounded to nearest degree )

2d)

they ask us to find ∠E

I'll , again, use the letter they give us for variables

Sin(E) / e = Sin( F ) / f

Sin(E) / 18 = Sin(78) / 30

E = arcSin[ 18 * Sin(78) / 30 ]

E = arcSin [ 0.5868856 ]

E = 35.936 °

E = 36 °    ( rounded to nearest degree )

Answer:

a) 0.2 = 20% probability that both the husband and wife are hired

b) 0.4 = 40% probability that one is hired and one is not

Step-by-step explanation:

A probability is the number of desired outcomes divided by the number of total outcomes.

The order in which the people are chosen is not important, which means that we use the combinations formula to solve this question.

Combinations formula:

[tex]C_{n,x}[/tex] is the number of different combinations of x objects from a set of n elements, given by the following formula.

[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]

(1) What is the probability that both the husband and wife are hired?

Desired outcomes:

Both selected, only one possible outcome, so [tex]D = 1[/tex]

Total outcomes:

4 from a set of 5. So

[tex]T = C_{5,4} = \frac{5!}{4!1!} = 5[/tex]

Probability:

[tex]p = \frac{D}{T} = \frac{1}{5} = 0.2[/tex]

0.2 = 20% probability that both the husband and wife are hired

(2) What is the probability that one is hired and one is not?

Desired outcomes:

One selected, one not, so two possible outcomes(Wife yes, husband not, or husband yes and wife not). So [tex]D = 2[/tex]

Total outcomes:

4 from a set of 5. So

[tex]T = C_{5,4} = \frac{5!}{4!1!} = 5[/tex]

Probability:

[tex]p = \frac{D}{T} = \frac{2}{5} = 0.4[/tex]

0.4 = 40% probability that one is hired and one is not

Answer:

Tennis – It's not difficult to see that tennis and volleyball have their similarity; both involve hitting a ball over the net in the hope that the opponent won't be able to return it. Much like tennis, volleyball requires short and explosive movements and cat-like reflexes, rather than long runs down a pitch.

Answer:

It is the graph of y=2x translated 4 units downward

Step-by-step explanation:

Given

[tex]y = 2x[/tex] to [tex]y' = 2x - 4[/tex]

Required

We have:

[tex]y = 2x[/tex]

Subtract 4 from both sides [In other words, shift downward by 4 units]

[tex]y - 4 = 2x - 4[/tex]

This implies that:

[tex]y' = y -4[/tex]

Substitute [tex]y = 2x[/tex]

[tex]y' = 2x -4[/tex]

Answer:

It is the graph of y = 2x translated 4 units downward.

It is the graph of y = 2x translated 2 units to the right.

Step-by-step explanation:

Recall that f(x) − k is a vertical translation that translates f(x) down k units. And, a vertical translation also translates a function horizontally, and vice versa. So, y = 2x − 4 translates the function y = 2x down 4 units. But 2x − 4 is also equal to 2(x − 2), so y = 2x − 4 also describes a translation to the right by 2 units.

Answer:

(C)

Step-by-step explanation:

looking from the slope: f'(2) is negative

f(2)=0

the curve concave upward: f''(2) is positive

f'(2)<0

f(2)=0

0<f''(2)

f'(2)<0<f''(2)

The expression which is true n the graph of a twice differential function is f' (2) < 0 < f'' (2) so, option C is correct.

A function that has a derivative at each point in its domain is referred to as a differentiable function of one real variable in mathematics. In other words, each interior point in the domain of a differentiable function's graph has a non-vertical tangent line.

Given:

The coordinate of the graph is shown in figure  (2, 0),

As we can see from the graph, the slope: f' (2) is negative (Downwards)

Again, from the graph

f(2) = 0

Thus, the curve concave upward: f'' (2) is positive (upward)

f' (2)<0

f (2)=0

0 < f'' (2)

f' (2) < 0 < f'' (2)

Therefore, f' (2) < 0 < f'' (2) is true in the given graph.
