Answer:

(x - 6) • (4x - y)

Step-by-step explanation:

brainly???

Step by step solution :

Step 1 :

Equation at the end of step 1 :

(4x • (x - 6)) - y • (x - 6)

Step 2 :

Equation at the end of step 2 :

4x • (x - 6) - y • (x - 6)

Step 3 :

Pulling out like terms :

3.1 Pull out x-6

After pulling out, we are left with :

(x-6) • ( 4x * 1 +( y * (-1) ))

Final result :

(x - 6) • (4x - y)

Which double-angle or half-angle identity would you use to verify that 1+cos2a=2/1+tan2a?

juin [17]

In this case or scenario, the double-angle identity that should be used is the one for cosine. 

In totality, we shall need the following three trigonometric identities to end up with the equality:

1. cos (2a) = cos² (a) - sin² (a)
2. sin² (a) + cos² (a) = 1
3. tan² (a) + 1 = sec² (a)

Using identities 1 and 2 on the left-hand side of the equation, we get the following:

1 + cos (2a) = 1 + cos² (a) - sin² (a) = 2 cos² (a)

Recalling that cos² (a) = 1 / sec² (a) and applying identity 3, we find the following:

2 cos² (a) = 2 / sec² (a) = 2 / (1 + tan² (a))

Therefore giving us:

2 cos² (a) = 2 / (1 + tan² (a))

What method would be best to use 53=4(x-3)^2-11

Veronika [31]

Answer:

x = 7 , -1

Step-by-step explanation:

SOLUTION :-

$4(x-3)^2-11 = 53$

Add 11 to both the sides.

$=> 4(x-3)^2-11+11=53+11$

$=> 4(x-3)^2 = 64$

Divide both the sides by 4.

$=> \frac{4(x-3)^2}{4} = \frac{64}{4}$

$=> (x-3)^2 = 16$

Root square both the sides.

$=> \sqrt{(x-3)^2} = \sqrt{16}$

$=> x-3 = +4 \; or -4$

Here , x will have two values -

1) $x-3 = 4$

$=> x = 4 + 3 = 7$

2) $x - 3 = -4$

$=> x = -4 + 3 = -1$

VERIFICATION :-

When x = 7 ,

$4(x-3)^2 - 11 = 4(7 - 3)^2 - 11$

$= 4 \times 4^2 - 11$

$= 4 \times 16 - 11$

$= 64 - 11$

$= 53$

When x = -1 ,

$4(x-3)^2 - 11 = 4(-1 - 3)^2 - 11$

$= 4 \times (-4)^2 - 11$

$= 4 \times 16 - 11$

$= 64 - 11$

$= 53$

Two random variables x and y are independent if the value of x does not affect the value of y. If the variables are not indepen

jeyben [28]

Answer: $\mu_{x+y} =$ 3026

$\mu_{x-y}=$ 30

Step-by-step explanation: Average sum of the female and male's test score is the sum of expected value of each gender:

$\mu_{x+y}=\mu_{x}+\mu_{y}$

Assuming x represents the random male selected and y represents the random female selected:

$\mu_{x+y}=1528+1498$

$\mu_{x+y}=$ 3026

The average sum of their scores is 3026.

Average difference is the difference between the expected value (mean) of each gender:

$\mu_{x-y}=\mu_{x}-\mu_{y}$

$\mu_{x-y}=$ 1528 - 1498

$\mu_{x-y}=$ 30

The average difference of their scores is 30.

Add and simplify 9/16 plus 1/2

Hitman42 [59]

= 9/16 + 1/2
convert 1/2 to same denominator as 9/16

= 9/16 + 8/16
add numerators

= (9+8)/16

= 17/16
convert to mixed number

= 1 1/16

ANSWER: 1 1/16

Hope this helps! :)
