klasskru [66]2 years ago
7 0

Answer:

-1+3i

Step-by-step explanation:

\sqrt{25}  -  \sqrt{ - 25}  -  \sqrt{36}  -  \sqrt{ - 4}

Sqr root of 25 and 36 are 5 and 6 respectively

Sqr root of -25 and -4 are 5i and 2i respectively

Combine like with like

5-6=-1

5i-2i=3i

-1+3i

PLEASE HELP!!<br><br> what is the explicit formula for this sequence -7, -4, -1, 2, 5
trasher [3.6K]

Answer:

The explicit formula for the given expression is a_n=-10+3n.

Step-by-step explanation:

The given sequence is

-7, -4, -1, 2, 5

The difference between two consecutive terms is same, therefore the given sequence is an arithmetic sequence.

The first term of the given AP is -7 and the common difference is

-4-(-7)=-4+7=3

The explicit formula for an AP is

a_n=a+(n-1)d

Where, a is first term, d is common difference and n is number of terms.

Substitute a=-7 and d=3 in the above equation.

a_n=-7+(n-1)3

a_n=-7+3n-3

a_n=-10+3n

Therefore the explicit formula for the given expression is a_n=-10+3n.

Why can 2 obtuse angles make a right triangle please help
djverab [1.8K]
They can NOT.  A right angle is 90°.  An obtuse angle is greater than 90°.  All the angles in a triangle must add up to exactly 180°.  If two angles are greater than 90° then they will add up to greater than 180, beacuse 90 plus 90 equals 180.  You cannot have a triangle with two obtuse angles because they will add up to greater than 180°.

3p - 2(p-4) = 7p + 6
Serggg [28]

For this case we must find the value of the variable "p" of the following equation:

3p-2 (p-4) = 7p + 6

We apply distributive property on the left side of the equation taking into account that +*-=-  and - * - = +:

3p-2p + 8 = 7p + 6

We add similar terms:

p + 8 = 7p + 6

We subtract 7p  from both sides of the equation:

p-7p + 8 = 6\\-6p + 8 = 6

We subtract 8 from both sides of the equation:

-6p = 6-8\\-6p = -2

We divide by -6 on both sides of the equation:

p = \frac {-2} {- 6}\\p = \frac {1} {3}

Answer:

p = \frac {1} {3}
