Plz I need help this is due at 7:10 and I wasn’t paying attention in class.

Answer:

7a-10b+6b+2a+9a=?

7a+2a+9a= 18a

-10b+6b= -4b

Final: 18a-4b

Answer:

[tex]Total = 2.35n[/tex]

Step-by-step explanation:

Given

Monday = n

Tuesday = 90% of Monday

Wednesday = 50% of Tuesday

Required

Determine the total miles

We have:

Tuesday = 90% of Monday

Substitute n for Monday

Tuesday = 90% of n

[tex]Tuesday = 90\% * n[/tex]

Express percentage to decimal

[tex]Tuesday = 0.90 * n[/tex]

[tex]Tuesday = 0.90n[/tex]

We also have that:

Wednesday = 50% of Tuesday

Wednesday = 50% * Tuesday

Substitute 0.90n for Tuesday

[tex]Wednesday = 50\% * 0.90n[/tex]

Express percentage to decimal

[tex]Wednesday = 0.50 * 0.90n[/tex]

[tex]Wednesday = 0.45n[/tex]

The total number of miles is:

[tex]Total = Monday + Tuesday + Wednesday[/tex]

[tex]Total = n + 0.90n + 0.45n[/tex]

[tex]Total = 2.35n[/tex]

Answer:

12

Step-by-step explanation:

12 is what she ended with and spent half of the weekly allowance and got 6 for the car wash.

so 12 - 6 is 6 which is the money she has after the movies but before the car wash.

And before the movies she has 12$ a week

Answer:

a & b=a

Step-by-step explanation:

If a triangles' degrees are 45° 45° and 90°; you have what is called a Special Right Triangle. This is simple and easy to understand with the right equations and setup. Draw yourself a right triangle with side a & b being the same length, label your triangle and angles. I am guessing with the limited question that your side x is either side a or b on your triangle, which means they are both the same length. But if you have a measurement for side c, your hypotenuse, the equation would be: c

[tex] \frac{c \sqrt{2} }{2} [/tex]

Answer:

To find the sum of interior angles of a polygon, multiply the number of triangles in the polygon by 180°. The formula for calculating the sum of interior angles is ( n − 2 ) × 180 ∘ where is the number of sides. All the interior angles in a regular polygon are equal.

Answer:

so 1/2 of those socks aren't blue?

Answer:

Step-by-step explanation:

d=20t+1/3, b=30t

20t+1/3=30t

10t=1/3

t=1/30 hr

t=(1/30)60=2 min

Compute the first few derivatives to reveal a pattern:

f(x) = x sin(x)

f '(x) = x cos(x) + sin(x)

f ''(x) = (-x sin(x) + cos(x)) + cos(x) = -x sin(x) + 2 cos(x)

f '''(x) = (-x cos(x) - sin(x)) - 2 sin(x) = -x cos(x) - 3 sin(x)

f ''''(x) = (x sin(x) - cos(x)) - 3 cos(x)) = x sin(x) - 4 cos(x)

f ⁽⁵⁾(x) = (x cos(x) + sin(x)) + 4 sin(x) = x cos(x) + 5 sin(x)

f ⁽⁶⁾(x) = (-x sin(x) + cos(x)) + 5 cos(x) = -x sin(x) + 6 cos(x)

f ⁽⁷⁾(x) = (-x cos(x) - sin(x)) - 6 sin(x) = -x cos(x) - 7 sin(x)

f ⁽⁸⁾(x) = (x sin(x) - cos(x)) - 7 cos(x) = x sin(x) - 8 cos(x)

and so on.

The pattern should be clear: for some integer k,

• if n = 4k, then f ⁽ⁿ ⁾(x) = x sin(x) - n cos(x)

• if n = 4k + 1, then f ⁽ⁿ ⁾(x) = x cos(x) + n sin(x)

• if n = 4k + 2, then f ⁽ⁿ ⁾(x) = -x sin(x) + n cos(x)

• if n = 4k + 3, then f ⁽ⁿ ⁾(x) = -x cos(x) - n cos(x)

80 is a multiple of 4, so the 80th derivative falls in the first category. Then

f ⁽⁸⁰⁾(x) = x sin(x) - 80 cos(x)
