please help me im so confused
................. plz let only deltaalex answer:) don’t trust anyone on here but them!
Answer:
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 )

Step-by-step explanation:
All you have to do is multiply 7x6 because u need to find the area.
but if u wanna find the perimeter u have to add all sides.
area is multiply 2 sides.

Assume that 5 people, including the husband and wife pair, apply for 4 sales positions. People are hired at random.
(1) What is the probability that both the husband and wife are hired?
(2) What is the probability that one is hired and one is not?
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

The chords intersect at point U.
A circle is shown. Chords R T and Q S intersect at point U. The length of R U is 12 centimeters, the length of U T is 4 centimeters, the length of U S is y centimeters, and the length of Q U is 8 centimeters.
What is the value of y?

6
8
Answer:
Its b)6
Step-by-step explanation:
I just did it on edge and got it correct
The value of y is 6 centimeters.
Given that,
The length of RU = 12 centimeters
The length of UT = 4 centimeters
The length of QU = 8 centimeters.
The length of US = y centimeters
What is the intersecting chords theorem?The intersecting chords theorem states that, the product of one whole chords segment and its external segment is equal to the product of the other whole chords segment and its external segment when two chords cross at an exterior point.
According to the intersecting chords theorem,
US x QU = RU x UT
Substitute the values in above formula,
y x 8 = 12 x 4
y = 48/8
y = 6 centimeters,
Hence, the value of y is 6 centimeters.

Step-by-step explanation:
you would find 5% of 53 which is $2.65 and then add that to your original price so 53 + 2.65 = 55.65
Select all the correct answers. Annie transforms the graph of y = 2x into the graph of y= 2x - 4. Which statements correctly describe this transformation?
Answer- Plato; It is the graph of y=2x translated 4 units downward. & It is the graph of y=2x translated 2 units to the right.
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.

2x + 3y = 13
x - 3y = 2
Answer:
use the 2nd equation to find that x=3y+2 and now plug it into the first equation to get 2(3y+2)+3y=13 distribute to get 6y+4+3y=13, reorganize the equation by adding common integers to become 9y+4=13, Subtract 4 from both sides to get 9y=13-4, or 9y=9, so y=1, plug that into the equation for x to get x=3+2, so y=1 and x=5
