Answer:
sin 2 ( x ) ⋅ sin 2 ( x ) cos 2 ( x ) → sin 2 ( x ) tan 2 ( x )
Step-by-step explanation:
Assuming tan = 2 ( x ) − sin 2 ( x ) = tan 2 ( x ) sin 2 ( x ) ,
tart off by rewriting tan 2 ( x ) in to its sin ( x ) and cos ( x ) components.
sin 2 ( x ) cos 2 ( x ) − sin 2 ( x )
Next find a common denominator
(LCD:
cos 2 ( x )⋅ 1 ) sin 2( x ) cos 2 ( x ) ⋅ ( 1 1 ) − sin 2 ( x ) ⋅ cos 2 ( x ) cos 2 ( x ) → sin 2 ( x ) cos 2 ( x ) − sin 2 ( x ) cos 2 ( x ) cos 2 ( x )
Combine in to a single fraction and factor out a
sin 2 ( x) . sin 2 ( x ) − sin 2 ( x ) cos 2 ( x ) cos 2 ( x ) → sin 2 ( x) ⋅ sin 2 ( x ) cos 2 ( x )
Finally just rewrite sin 2 ( x ) ⋅ sin 2 ( x ) cos 2 ( x ) → sin 2 ( x ) tan 2 ( x )

Find the excluded value of the function Y= - 10/6x-5. The excluded value is x =??
Answer:
The excluded value is x = 5/6
Step-by-step explanation:
Here, we want to calculate the excluded value
The excluded value is simply the value of x that will make the denominator of the fraction equals zero
We have this as;
6x -5 = 0
6x = 5
x = 5/6
Can someone tell me what the answer is for x/-9≥3 as a simplified answer
rocket is launched from a tower. The height of the rocket, y in feet, is related to the
time after launch, a in seconds, by the given equation. Using this equation, find out
the time at which the rocket will reach its max, to the nearest 100th of a second.
y=16x^2+ +225x+79
Answer:
7.03 seconds
Step-by-step explanation:
First, you need to differentiate the equation (The derivative of y represents the rocket's velocity):
y' = 32x + 225
Then, set y' to 0 and solve for x
0 = 32x + 225
x = 7.03s

2/y-1 - 4/y^2-1
Answer:
[tex]\frac{2}{y+1}[/tex]
Step-by-step explanation:
Factorise the denominator of the second fraction
y² - 1 = (y - 1)(y + 1) ← difference of squares
To obtain a common denominator
multiply numerator/ denominator of first fraction by (y + 1)
= [tex]\frac{2(y+1)}{(y-1)(y+1)}[/tex] - [tex]\frac{4}{(y-1)(y+1)}[/tex] ← subtract numerators leaving the common denominator
= [tex]\frac{2y+2-4}{(y-1)(y+1)}[/tex]
= [tex]\frac{2y-2}{(y-1)(y+1)}[/tex]
= [tex]\frac{2(y-1)}{(y-1)(y+1)}[/tex] ← cancel common factor (y - 1) on numerator/denominator
= [tex]\frac{2}{y+1}[/tex]

Hallie made 12 quarts of homemade yogurt. She put the yogurt in 34-cup containers. How many containers did Hallie fill?
Answer:
1 container and 14 cups
Step-by-step explanation:
We know that 1 quart = 4 cups
therefore, 12 quart = 48 cups
each container has 34 cups
so one container would be full and remaining 48-34 =14 cups can be filled in another container.

Rectangle 1 has length 10 and width 20. Rectangle 2 is made by multiplying each dimension of Rectangle 1 by a factor of k=3
Answer:
30cm, 60cm
Step-by-step explanation:
Given data
Dimensions of the first rectangle
Length =10cm
Width =20cm
We are told that the dimensions of the second rectangle is gotten by multiplying the first rectangle by 3
Hence the dimensions of the second rectangle is
Length =10*3= 30cm
Width = 20*3= 60cm
The sum of 3 consecutive integers is 30.
What is the third number in this sequence?
Answer:
11
Step-by-step explanation:
the 3 numbers are 9, 10, 11
Answer:
Third number = 11
Step-by-step explanation:
Let 3 consecutive numbers be x ,x +1 , x +2
x +x+1 + x+ 2 = 30
x +x +x + 1 + 2 = 30 {Combine like terms}
3x + 3 = 30 {Subtract 3 from both sides}
3x = 30 - 3
3x = 27 {Divide both sides by 3}
x = 27/3
x = 9
Third number =x + 2 = 9 + 2 = 11
find the value of x
please help
Answer:
Here we can see that two lines are intersecting so that the angles formed will be vertically opposite angles,
Thus, the value of both angles will be equal
i.e., x+3 = 84
⇒ x = 84 - 3
⇒ x = 81
Thus the value of x is 81

What is the final elevation if
a. A bird starts at 20 m and changes 16 m?
b. A butterfly starts at 20 m and changes -16 m?
c. A diver starts at 5 m and changes -16 m?
d. A whale starts at -9 m and changes 11 m?
e. A fish starts at -9 meters and changes -11 meters?
Answer:
it has to be b I don't know for sure tho
Answer:
A. So assuming we are dealing with displacement
20 + 16 = 32 m
B. 20 - 16 = 4m
C. 5 - 16 = - 11m
D. - 9 + 11 = 2m
E. - 9 - 11 = - 20m

please help!! i’ll mark best answer brainliest!!
Answer:
Z = 13
Step-by-step explanation:
Both of the angles should equal 90.
2z + 5 + 5z - 6 = 7z - 1
7z - 1 = 90
7z - 1 + 1 = 90 + 1
7z = 91
7z ÷ 7 = 91 ÷ 7
Z = 13

A delivery driver is traveling a total of 250 miles from a warehouse to a store at an average speed of 45 miles per hour. The function f(x)=250-45xf(x)=250−45x represents the distance remaining, in miles, after traveling for xx hours.
Answer:
115miles
Step-by-step explanation:
Given the function of the distance remaining represented by the function
f(x) =250-45x where;
x is the time taken in hours
Since we are not told what to loom for, we can calculate the distance remaining after 3hrs.
Substitute x =3 into the equation
f(3) = 250-45(3)
f(3) = 250-135
f(3) = 115
Hence the distance remaining after 3 hrs is 115miles

Find the area of the region shaded in green. Use 3.14 to approximate pi.
Answer:
254 cm² (to 3 s.f.)
Step-by-step explanation:
Area of shaded region
= area of large circle -area of smaller circle
[tex]\boxed{area \: of \: circle = \pi {r}^{2} }[/tex]
Radius of large circle= 15cm
Radius of smaller circle= 12cm
Area of shaded region
= π(15²) -π(12²)
= 225π -144π
= 81π
= 81(3.14)
= 254.34
= 254 cm² (3 s.f.)
