Answer:

1425 square kilometer.

Step-by-step explanation:

2900 - 8.5% = 2653.5

2653.5 - 8.5% = 2427.9525

2427.9525 - 8.5% = 2221.5765375

2221.5765375 - 8.5% = 2032.74253181

2032.74253181 - 8.5% = 1859.95941661

1859.95941661 - 8.5% = 1701.8628662

1701.8628662 - 8.5% = 1557.20452257

1557.20452257 - 8.5% =1 424.84213815 ≈ 1425

Which operation results in a binomial? (3y ^ 6 + 4) (9y ^ 12 - 12y ^ 6 + 16)
AleksAgata [21]

Step-by-step explanation:

Given the expression, (3y ^ 6 + 4)  (9y ^ {12} - 12y ^ 6 + 16), we want to know which sign placed in between the two polynomial will produce a binomial.

Using a plus (+) sign to check:

= (3y ^ 6 + 4) + (9y ^ {12} - 12y ^ 6 + 16)\\=  (3y ^ 6 + 4) + (9y ^ {12} - 12y ^ 6 + 16)\\collect \ like \ terms\\= 9y^{12} +3y^6 - 12y^6 + 16+ 4\\= 9y^{12} - 9y^6 + 20\\

From the gotten value, it can be seen that the resulting answer produces 3 terms, showing that it results in a trinomial instead of binomial.

Using a plus (-) sign to check:

= (3y ^ 6 + 4) - (9y ^ {12} - 12y ^ 6 + 16)\\=  3y ^ 6 + 4 - 9y ^ {12} + 12y ^ 6 - 16\\collect \ like \ terms\\= -9y^{12} +3y^6 +12y^6 + 4-16\\= -9y^{12} +15y^6 -12\\

From the gotten value, it can be seen that the resulting answer produces 3 terms, showing that it results in a trinomial instead of binomial.

<em>Hence none of the operations given results in a binomial</em>

How would you solve this?
siniylev [52]

Answer:

Step-by-step explanation:

hello :

(x-4)²(x+3)² = -1

means : ((x-4)(x+3))² = - 1 this equation has no solutions in R

because for all x in R : ((x-4)(x+3))² ≥ 0

Solve for &lt; x &lt; 180degrees
Tamiku [17]

Option C: 90° is the value of x.

Explanation:

The given expression is 4+2 \sin x=14-8 \sin x for 0^{\circ} \leq x \leq 180^{\circ}

We need to solve the expression.

Thus, we have,

4+2 \sin x=14-8 \sin x

Subtracting both sides by 4, we have,

2 \sin x=10-8 \sin x

Adding both sides by 8 sin x, we get,

10 \sin x=10

Dividing both sides by 10, we have,

sin \ x=1

Taking sin^{-1} on both sides of the equation, we get,

x=sin^{-1}(1)

x=90^{\circ}

Thus, the value of x is 90°

Hence, Option C is the correct answer.

I need help with similar triangles
Alika [10]

Answer:

ΔGHI and ΔDEF  are similar by SSS criteria

Step-by-step explanation:

Consider triangle GHI and triangle DEF

In ΔGHI, GH = 2, HI =4 and GI = 3.5

In ΔDEF , DE =4, EF = 6 and DF = 7

GH/DE = 2/4 =1/2

HI/EF = 3/6 = 1/2

GI/DF = 3.5/7 = 1/2

The corresponding sides are in same ratio by SSS criteria

ΔGHI and ΔDEF  are similar
