2.) Fill in the blank.
Montano1993 [528]

Answer:

E.) 1

Step-by-step explanation:

Firstly we will solve for L.H.S.

L.H.S. =Csc^2\theta

Since we know that Csc^2\theta is the inverse of Sin^2\theta.

So we can say that;

csc^2\theta=\frac{1}{sin^2\theta}

Now For R.H.S.

Cot^2\theta+1

Since we  can rewrite cot^2\theta as \frac{cos^2\theta}{sin^2\theta}.

Now we can say that the R.H.S. is;

\frac{cos^2\theta}{sin^2\theta}+1

Now we add the fraction and get;

\frac{cos^2\theta+sin^2\theta}{sin^2\theta}

Now according to trigonometric identity;

cos^2\theta+sin^2\theta=1

So, \frac{cos^2\theta+sin^2\theta}{sin^2\theta}=\frac{1}{sin^2\theta}

Here,

csc^2\theta=\frac{1}{sin^2\theta}   and     Cot^2\theta+1 = \frac{1}{sin^2\theta}<em>  </em>

L.H.S. = R.H.S.

Hence csc^2\theta=cot^2\theta+1

Janine inflated a ball to a radius of 18 cm and another ball to a radius of 12 cm.
Sladkaya [172]
Volume of a ball = (4/3)πr³

When r = 18cm, V = (4/3)×3.14×18³ =24416.64 cm³
When r = 12cm, V = (4/3)×3.14×12³ =7234.56 cm³
 Difference = 24416.64 - 7234.56 = 17182.08 cm³

the volume of air in the larger ball is <span>17182.08 cm³ greater than smaller ball </span>

I need this done plz
KIM [24]

Answer:

13. -28 = p

12. 5 = r

11. -12 = t

10. -8 = q

9. -77 = s

8. 9 = w

7. 12 = y

6. 3 = a

5. 9 = n

4. 3 = x

3. 12 = y

2. 5 = c

1. 5 = m

DON'T GET HOOKED

Step-by-step explanation:

13. 1 + p \div 7 = -3 \\ \\ p\div 7 = -4 \\ \\ -28 = p

12. 5[r + 4] = 45 \\ \\ r + 4 = 9 \\ \\ 5 = r

11. t \div 4 - 3 = -6 \\ \\ t \div 4 = -3 \\ \\ -12 = t

10. -4 + 11q = -92 \\ \\ 11q = -88 \\ \\ -8 = q

9. s \div 7 + 8 = -3 \\ \\ s \div 7 = -11 \\ \\ -77 = s

8. w \div 3 + 3 = 6 \\ \\ w \div 3 = 3 \\ \\ 9 = w

7. y \div 3 - 4 = 0 \\ \\ y \div 3 = 4 \\ \\ 12 = y

6. 3[a + 5] = 24 \\ \\ a + 5 = 8 \\ \\ 3 = a

5. 14 = 2n - 4 \\ \\ 18 = 2n \\ \\ 9 = n

4. 3x + 6 = 15 \\ \\ 3x = 9 \\ \\ 3 = x

3. 6y - 11 = 61 \\ \\ 6y = 72 \\ \\ 12 = y

2. 9c - 4 = 41 \\ \\ 9c = 45 \\ \\ 5 = c

1. 2m + 2 = 12 \\ \\ 2m = 10 \\ \\ 5 = m
