Can You Guys Help We With This Question.

Answers

Answer 1

Answer:

40

Step-by-step explanation:

(2x+1/(2x))^5 *(2x -1/(2x))^5

= ((2x)^2 -1/(2x)^2)^5 (a+b)*(a-b) =a2-b2

= (4x^2-1/4(x)^2)^5

now

x =4x^2. ,a = 1/4(x)^2 ,n =5

we have

general term = Cr *x^r *a^(n-r)

= Cr * (4x^2)^r * (1/4(x)^2)^(n-r)

= Cr *4^r * X^2r * 1/( 4^(n-r) *x^(2n-2r)

= Cr * 4^r/4^(n-r) * x^(2r)/x^(2n-2r)

= Cr * 4(2r-n) *x(4r-2n)

now for x^2

4r-2n = 2

4r -10=2

4r =12

r = 3

now for coeff

C(5,3) * 4^(2*3-5)

5!/(3!*(5-3)!) * 4

5*4/(2*1)*4

40

Answer 2
4r-2n=2

4r-10=2

4r=12

R=13

Find the measure of the arc. Please help!

Answers

Answer:

The value of mEFD = 214°

Step-by-step explanation:

Given that the measure of the degree of one of the central angles of an inner circle is 146°.

We know that sum of all central angles is 360°.

In other words, in our case

mEFD + 146° = 360°

Thus, we can determine the mEFD using the equation

mEFD + 146° = 360°

so subtracting 146° to both sides

mEFD + 146° - 146°  = 360° - 146°

mEFD = 214°

Therefore, the value of mEFD = 214°

What is the measure of
A. 60°
B. 80°
C. 110°
D. 120°

Answers

Answer:

A. 60 degrees

Step-by-step explanation:

The sum of the abgles in a triangle is 180°. We are already given 96° and 24°.

so we will subtract the given values from 180 to find the third angle

180-(96+24)=180-120=60°

The answer is A. 60°

The angle of a quadrilateral are in the ratio 4:6:3 and it's fourth angle is 100. Find the other three angles of the quadrilateral

Answers

Step-by-step explanation:

Sum of angles in a quadrilateral = 360°

Sum of first 3 angles = 360° - 100° = 260°.

260° / (4 + 6 + 3) = 20°.

First angle = (20°) * 4 = 80°

Second angle = (20°) * 6 = 120°

Third angle = (20°) * 3 = 60°

The angles are 80°, 120° and 60°.

Answer:

Let the angles of the quadrilateral be 4x, 6x, and 3x

Sum of the interior angles of a quadrilateral is 360°.

According to the above problem,

[tex]4x + 6x + 3x + 100 = 360 \\ 13x = 360 - 100 \\ 13x = 260 \\ \boxed{x = 20}[/tex]

1st angle=4x=4×20=80°2nd angle=6x=6×20=120°3rd angle=3x=3×20=60°

Hence, the other three angles are 80°, 120° and 60°.

Answers

Answer:

First you have to plot Bart's Garage's fee. Bart's equation is y = 30x + 20, so you would need to plot the points (0, 20) and (1, 50).

Lisa's base fee is the same, so her equation would have a + 20 at the end of it, but her hourly fee is higher. Therefore her hourly fee would be higher than 30. Her equation could be anything above 30, y = 50x +20 would work. The points for that graph are (0, 20) and (1, 70).

chicken tenders or chicken nuggets

Answers

Answer:

i dont know which one to choose but chicken tenders

Answer:

Chicken tenders.

Step-by-step explanation:

Chicken nuggets are the gross consumption of organs including lungs and others mushed together and fried. In return kids run to it because (most) kids only eat gross stuff. This made the marketing campaign SKY ROCKET with kids everywhere trying to get a bite. FORCING their poor parents to get them that disgusting mush. And then dip it in ketchup. Which is NOT a fruit or veggie. (As the school system thinks they are a veggie.)

While chicken tenders are chopped off the chicken meat then rolled in bread crumbs. And then deep fried to make a crispy exterior with a delicious tender interior.  Without getting mushed together with other things.

Also you never know what they put in that chicken nugget since its mushed together ‍♀️.

Gilbert is -17 meters under sea level every second(s) he gains 0.5 meters after how many seconds is he at sea level?

Answers

Answer:

He is at sea level after 34 seconds

Step-by-step explanation:

The height at sea level is given as 0 meters

So the change in height would be;

0- (-17) = 17 meters

There is a gain of 0.5 meters in 1 second

So, the time taken for it to gain 17 meters will be 17/0.5 = 34 seconds
