Answer:

Concept: Vectors

  1. I think the confusion here might be the usage of i and j
  2. Just to let you know, i=x and j=y
  3. So let's use that fact to conceptualize this
  4. 6x^3+4y^2-6x
  5. We can simplify by applying a common factor
  6. 2(x^3+2y^2-3x)
  7. Thats the most we can simplify this

Can you help me out it would be much appreciate thank you
brilliants [131]

Answer:

The answer to the question is 50.28 feet²

Step-by-step explanation:

Here, is why the answer to the problem is 13.72!

The area of the shaded region is:-

Area of total region - Area of the circular region

Area of total region is 8² so it is 64 feet²

Area of Circular region formula is πr²

Substitute the values, for the formula and it is π4² = 22/7 × 16

                                                                         → 352/7

                                                                        ⇒ 13.72 Feet²

Therefore, the area of the shaded region is 13.72 Feet²

(Now, we subtract the two values)

64 - 13.72

⇒ 50.28 Feet²

I hope this answer helps!

Which system is equivalent to<br> y= 9x^2<br> x+y=5<br> ?
melomori [17]

Answer : Option A

Explanation:

we can clearly see that from x+ y=5 we can substitute  y = 5-x in y = 9x^2

Option B is clearly incorrect  x can not be y -5

Option C  is incorrect because y can not be 5 +x

Option D is incorrect because  its y = 9x^2 not y^2 =9x^2 so y can not be 3x

if its y^2 = 9x^2 then  only  implies y =  3x

4. what is the value of x?
Eva8 [605]

Answer:

4. 21

5.120

Step-by-step explanation:

(the answer for #4

I added 5x+15 and 3x-3

and got

8x+12

and because we needed to find the value of x, l did this

8x+12=180

because interior consecutive angles equal 180

and I got 21

(answer for 5)

I then plugged 21 into 5x+15 because angle 1 is equal to it

5(21)+15

I got 120
