Q2: 160 + 120 + 210 + 70 + 90 + 90 = 740

Q3: (160 x 120) + (70 x 90) = 25500

19200 + 6300

Q5: As = 1/2 $\pi$ (6cm)^2

(6cm)^2 = 36cm

1/2 $\pi$ (36)

\pi = 3.14159 x 36 = 113.09 / 2 = 56.54 cm^2 area

12 x 7 = 84 + 56.54 = 140.54cm^2

Q6: 11 + 9 + 20 + 14 = 54

Q7: 9 x 11 = 99

11 x 11 = 122 / 2 = 61 99 + 61 = 160^2

Please help been stuck on this for 40 minutes

choli [55]

we have given y interms of x.

we have given that add 2 to x.

which means $y=x+2$

so we have $x=2 ,y=x+2=2+2=4$ .

so when x $=2 ,y=4$ .

$x=4,y=x+4=4+2=6.$ .

$y=x+2,y=6+2=8$ .

Does 2^8 equal (3sqrt{16})^6

ale4655 [162]

Answer:

Does 2⁸ = (3√16)⁶? No.

Step-by-step explanation:

2⁸ = (3√16)⁶

Evaluate 2⁸. This can simply be written out as:

2 * 2 * 2 * 2 * 2 * 2 * 2 * 2

4 * 2 * 2 * 2 * 2 * 2 * 2

8 * 2 * 2 * 2 * 2 * 2

16 * 2 * 2 * 2 * 2

32 * 2 * 2 * 2

64 * 2 * 2

128 * 2

256.

256 = (3√16)⁶

Evaluate √16.

256 = (3*4)⁶

Multiply 3 and 4.

256 = 12⁶

Evaluate 12⁶. This can be rewritten as:

12 * 12 * 12 * 12 * 12 * 12

144 * 12 * 12 * 12 * 12

1728 * 12 * 12 * 12

20736 * 12 * 12

248832 * 12

2985984.

Since 256 ≠ 2985984, the answer to this question is no.

Choices; a) 21.8° b) 35.2° c) 45.1°

kifflom [539]

Answer:

$\displaystyle a) \: {x}^{ \circ} = 21.8 ^{ \circ}$

Step-by-step explanation:

we are given opposite and adjacent

we want to figure out x°

remember that,

$\displaystyle \: \tan( \theta) = \frac{opp}{adj}$

where our opp is 5 and adj is 12.5

let $\theta$ be x°

$\displaystyle \: \tan( {x}^{ \circ} ) = \frac{5}{12.5}$

$\displaystyle \: {x}^{ \circ} = \arctan \left( \frac{5}{12.5} \right)$

by using calculator

$\displaystyle \: {x}^{ \circ} = 21.8$

hence,

our answer is a

If 4^x+1 = 64, then what is the value of x^4

Olin [163]

$4^{x} + 1 = 64 \\4^{x} = 63 \\ln(4^{x}) = ln(63) \\xln(4) = ln(63) \\x = \frac{ln(63)}{ln(4)}$

$(\frac{ln(63)}{ln(4)})^{4} = 79.78006702$

The value of x⁴ is equal to 79.8006702
