In right triangle ABC, m∠ B ≠ m∠ C. Let sin B = r and cos B = s.
What is sin C – cos C?
Answers
Draw and label a diagram.
sin A = CB / AB
cos B = CB / AB
sin A = cos B
2x - 1.3 = 5x
Can you solve for x and answer?
The value of expression sin C - cos C is,
⇒ r - s
What is mean by Triangle?Triangle is a three sided polygon, which has three vertices and three angles and which has sum 180 degrees.
Given that;
In right triangle ABC,
⇒ m∠ B ≠ m∠ C.
Let us assume that,
⇒ sin B = r
And, cos B = s.
Now, We get;
sin B = rh / h
= r
And, cos B = sh / h
= s
Hence, We can formulate;
sin C = sh / h = s
cos C = rh / h = r
Thus, We get;
⇒ sin C - cos C
⇒ r - s
Therefore, The value of expression sin C - cos C is,
⇒ r - s

In a game involving a standard deck of 52 playing cards, an individual randomly draws 7 cards without replacement. Let y = the number of kings drawn. Is y a binomial variable? Why or why now?
Answers
Answer:
Step-by-step explanation:
By definition, we will see that y is a binomial variable.
Here the variable "y" represents:
y = "number of kings drawn"
When we draw 7 cards out of a 52 cards deck.
So there are 5 possible values of y:
y = 0y = 1y = 2y = 3y = 4A binomial variable is a variable that represents two outcomes, for example, if we used the variable x = "drawing a king" 7 times, then x is a binomial variable, because it has two outcomes, or you draw a king, or you don't.
A binomial variable can also represent the number of outcomes of each type for several events like x (the one defined above). This is what y does, it counts how many times the outcome of "x" is "drawing a king" for a sequence of 7 draws.
Then y is a binomial variable.

Mica stands 75 feet away from the base of a tree and looks up towards the top of the tree at a 51 degree angle.
Answers
Answer:
Height of the tree = 92.61 feet
Step-by-step explanation:
Given: Distance between base of tree and Mica = 75 feet
Angle of elevation to the top of tree = 51°
Assuming we have to find the height of the tree = H
This can be found by applying simple trigonometry.
The height of the tree becomes perpendicular and distance between base of tree and Mica is base.
Then, tan51° = H/75
⇒ H = 75× tan51° = 92.61 feet

Ok so for question one we use the Pythagorean theorem, which is a^2+b^2=c^2
a is the shortest leg, b is the leg that is not the hypotenuse. and c is the hypotenuse which is the opposite leg to the right angle.
Question 1: a=9,b=12,c=x
(9)^2+(12)^2=(x)^2
81+144=(x)^2
225=(x)^2
x=15
Question 2: a=10,b=24,c=x
(10)^2+(24)^2=(x)^2
100+576=(x)^2
676=(x)^2
x=26
Question 3: a=3,b=7,c=x
(3)^2+(7)^2=(x)^2
9+49=(x)^2
58=(x)^2
x=root58, or 7.615773
Question 4: a=6,b=x, c=10
(6)^2+(x)^2=(10)^2
36+(x)^2=100
Subtract 36 from both sides
(x)^2=64
x=8
Question 5: a=6,b=x, c=24
(6)^2+(x)^2=(24)^2
36+(x)^2=576
Subtract 36 from both sides
(x)^2=540
x=6root15, or 23.2379
Question 6: a=1, b=1, c=x
(1)^2+(1)^2=(x)^2
1+1=(x)^2
2=(x)^2
x=root2, or 1.414213562
Question 7: a=8, b=x, c=21
(8)^2+(x)^2=(21)^2
64+(x)^2=441
Subtract 64 from both sides
(x)^2=377
x=root377, or 19.41648784
Question 8: a=24, b=x, c=30
(24)^2+(x)^2=(30)^2
576+(x)^2=900
Subtract 576 from both sides
(x)^2=324
x=18
Question 9: a=5,b=9, c=x
(5)^2+(9)^2=(x)^2
25+81=(x)^2
106=(x)^2
x=root106, or 10.29563014
Question 9 Part B: a=3, b=5, c=y
(3)^2+(5)^2=(y)^2
9+25=(y)^2
34=(y)^2
root34, or 5.830951895=y

Answers
Answer:
The width of the garden is 7 feet.
Step-by-step explanation:
If the area is 56 feet, and the length is 8 feet, we can put this into the area equation.
Area = width * length
A = wl
Substitute variables.
56 = 8w
Divide by 8.
7 = w, or w = 7.
The width of the garden is 7 feet.

Step-by-step explanation:
y=38(0.29)^x is an exponential function whose initial value (when x = 0) is 38. This function increases steadily from this value, due to the +(0.29) base of this exponential. As x grows increasingly large, the rate at which y is increasing drops steadily.
