Answer:
[tex]\frac{115}{132}[/tex]
Step-by-step explanation:
[tex](\frac{1}{2} )^{2} * \frac{9}{11} + \frac{2}{3}[/tex]
= [tex]\frac{1}{4} * \frac{9}{11} + \frac{2}{3}[/tex]
= [tex]\frac{9}{44} + \frac{2}{3}[/tex]
= [tex]\frac{27 + 88}{3(44)}[/tex]
= [tex]\frac{115}{132}[/tex]
sin(A+B)/sin A cos B
= 1 + cot A tan B
how to verify the identity?
Answer:
see explanation
Step-by-step explanation:
Using the identities
sin(A + B) = sinAcosB + cosAsinB
cotA = [tex]\frac{cosA}{sinA}[/tex] , tanA = [tex]\frac{sinA}{cosA}[/tex]
Consider the left side
[tex]\frac{sin(A+B)}{sinAcosB}[/tex]
= [tex]\frac{sinAcosB+cosAsinB}{sinAcosB}[/tex]
= [tex]\frac{sinAcosB}{sinAcosB}[/tex] + [tex]\frac{cosAsinB}{sinAcosB}[/tex]
= 1 + [tex]\frac{cosA}{sinA}[/tex] . [tex]\frac{sinB}{cosB}[/tex]
= 1 + cotA tanB = right side , thus verified

I need the endear for number six. Will give brainliest for help/answer.
Answer:
f(1) = 2, f(4) = 8
Step-by-step explanation:
f(1) in the interval - 3 < x ≤ 1 , then f(x) = x + 1 , so
f(1) = 1 + 1 = 2
f(4) in the interval 1 < x ≤ 4 , then f(x) = 2x , so
f(4) = 2 × 4 = 8

What is the intermediate step in the form (x+a)^2=b(x+a)
2
=b as a result of completing the square for the following equation?
6x^2+48x+207=15
Answer:
The intermediate step are;
1) Separate the constants from the terms in x² and x
2) Divide the equation by the coefficient of x²
3) Add the constants that makes the expression in x² and x a perfect square and factorize the expression
Step-by-step explanation:
The function given in the question is 6·x² + 48·x + 207 = 15
The intermediate steps in the to express the given function in the form (x + a)² = b are found as follows;
6·x² + 48·x + 207 = 15
We get
1) Subtract 207 from both sides gives 6·x² + 48·x = 15 - 207 = -192
6·x² + 48·x = -192
2) Dividing by 6 x² + 8·x = -32
3) Add the constant that completes the square to both sides
x² + 8·x + 16 = -32 +16 = -16
x² + 8·x + 16 = -16
4) Factorize (x + 4)² = -16
5) Compare (x + 4)² = -16 which is in the form (x + a)² = b

The height of a triangle is 2 less than 5 times its base. If the base of the triangle is x feet, and the area of the triangle is 12 square feet, which equation models this situation?
Answer:
12 = 1/2(x)(5x - 2)
Bonus solution for x = 2.4 ft
Step-by-step explanation:
area = 1/2xh
h = 5x - 2
12 = 1/2(x)(5x - 2)
24 = 5x² - 2x
5x² - 2x - 24 = 0
x² - 0.4x - 4.8 = 0
(x - 2.4)(x + 2) = 0
x = 2.4
Answer:
5x^2 − 2x − 24 = 0

Hi can you Please answer this i will mark brainliest ive been asking for 2 days :( Its Overdue :(
Answer:
f(x)= 1.38x
y= 1.38x
Step-by-step explanation:
basically the cost= 1.38 per pound
you can use cost=1.38x if ur grade level isn't at f(x) yet
<3
Answer:
f(x) = 1.38x
x just stands for a number so depending on how many pounds you get you would times the pounds by 1.38. And f(x) (pronounced "f of x") means that each input has a single output. So if you bought 2 pounds of strawberries, the equation would change to this:
f(2) = 1.38(2)
The x's were just replaced with 2's, see? I wish someone had explained this to me earlier lol

Let f(-x) = 5x – 2 and g(x) = 2x + 3 and find f(x) –
f(0) — 9(x) = 7x – 1
f(.2) – 9(x) = 7x + 1
f(x) — 9(2) = 3x – 5
f(x) – 9(x) = -3x +5
Answer:
3x - 5
Step-by-step explanation:
Given that f(x) = 5x - 2 and g(x) = 2x+3
f(x) - g(x) = 5x-2 - (2x+3)
Expand
f(x) - g(x) = 5x - 2 - 2x - 3
Collect like terms
f(x) - g(x) = 5x - 2x -2-3
f(x) - g(x) = 3x - 5
Hence the required answer is 3x - 5
The coordinates of the vertices of triangle QRS are Q (1,-2), R (1,9),
S (6,-4). What is the length, in units, of the line segment that connects
vertex Q to vertex R?
I think 1700000000000000000
Answer:
QR = 11
Step-by-step explanation:
Q and R are on a vertical line. Therefore, QR = 9 - (-2) = 9 + 2 = 11
using the graph below, determine the slope and equation of the line
(easy question, easy points)
Answer:
B. slope = Undefined, x = 3
Step-by-step explanation:
The equation of a vertical line always takes the form x = k, where k is any number and k is also the x-intercept .
So the slope for this is undefined, since it's just a vertical line so, since the equation is x = k. If it's horizontal then it's 0.
the best fit for this is the first option slope = undefined, x = 3.
slope: Undefined
x-intercept: 3
Answer:
Its undefined
Step-by-step explanation:
Vertical is undefined
Horizontal is Zero

Answer:
177 ft below sea level
Step-by-step explanation:
282
10 x 12 = 120. This represents how man ft the hot air balloon rose.
282 - 120 = 162. Keep in mind your still below sea level.
162 + 15 = 177
You add 15 because the hot air balloon is going down 15 feet which adds to being below sea level. ( Your going deeper/lower)
