Answer:

[tex]\sqrt{-25} = 5i[/tex]

Step-by-step explanation:

Given

[tex]\sqrt{-25[/tex]

Required

An equivalent

We have:

[tex]\sqrt{-25[/tex]

Express -25 as -1 * 25

[tex]\sqrt{-25} = \sqrt{-1 * 25}[/tex]

Split

[tex]\sqrt{-25} = \sqrt{-1} * \sqrt{25}[/tex]

[tex]\sqrt{25} = 5[/tex], so:

[tex]\sqrt{-25} = \sqrt{-1} * 5[/tex]

[tex]\sqrt{-1} = i[/tex] --- complex numbers

So:

[tex]\sqrt{-25} = i * 5[/tex]

[tex]\sqrt{-25} = 5i[/tex]

Hence, the equivalent is (D)

-1:23:12

Since the last part is un doable just add the minute into the seconds and take off a minute

1:38:64

-1:23:12

Answer:

[tex]a_{20} = 1/1048576[/tex]

Step-by-step explanation:

Given

[tex]Sequence: -1/2;1/4;-1/8;1/16[/tex]

Required

Determine [tex]a_{20[/tex]

Since it is a geometric sequence, first we need to calculate the common ratio (r)

[tex]r = \frac{a_2}{a_1}[/tex]

From the sequence:

[tex]a_2 = 1/4[/tex]

[tex]a_1 = -1/2[/tex]

[tex]a_1[/tex] is the same as [tex]a[/tex]

So:

[tex]r = \frac{a_2}{a_1}[/tex]

[tex]r = \frac{1/4}{-1/2}[/tex]

[tex]r = -1/2[/tex]

[tex]a_{20[/tex] is then calculated as:

[tex]a_n = ar^{n-1}[/tex]

Where

[tex]n = 20[/tex]

[tex]a_{20} = ar^{20-1}[/tex]

[tex]a_{20} = ar^{19}[/tex]

[tex]a_{20} = (-1/2) * (-1/2)^{19}[/tex]

Apply law of indices

[tex]a_{20} = (-1/2)^{1+19}[/tex]

[tex]a_{20} = (-1/2)^{20}[/tex]

Evaluate the exponent

[tex]a_{20} = 1/1048576[/tex]

Step-by-step explanation:

Answer:

1) 20.2

2) 13

3) 10.3

4) 103

Step-by-step explanation:

If you need help solving these on your own next time, here's the formula

a^2+b^2= c^2, or A to the power of two, plus B to the power of two, = C to the power of 2.

To solve them square both A and B, (ex. 9.2 to the power of two, plus 18 to the power of two, which equals 408.64.)

Then, to solve for x, (or c, doesn't matter the variable,) you square root the number.

(ex. √408.64, which is 20.2)

Given:

[tex]a_n=a_{n-1}+3[/tex]

[tex]a_0=2[/tex]

To find:

The values [tex]a_1,a_2,a_3[/tex].

Solution:

We have,

[tex]a_n=a_{n-1}+3[/tex]

For [tex]n=1[/tex],

[tex]a_1=a_{1-1}+3[/tex]

[tex]a_1=a_{0}+3[/tex]

[tex]a_1=2+3[/tex]

[tex]a_1=5[/tex]

For [tex]n=2[/tex],

[tex]a_2=a_{2-1}+3[/tex]

[tex]a_2=a_{1}+3[/tex]

[tex]a_2=5+3[/tex]

[tex]a_2=8[/tex]

For [tex]n=3[/tex],

[tex]a_3=a_{3-1}+3[/tex]

[tex]a_3=a_{2}+3[/tex]

[tex]a_3=8+3[/tex]

[tex]a_3=11[/tex]

Therefore, [tex]a_1=5,a_2=8,a_3=11[/tex].

The value of [tex]\rm a_1=5[/tex], [tex]\rm a_2=8[/tex], and [tex]\rm a_3=11[/tex] and this can be determined by using the arithmetic operations and the given data.

Given :

Let {an} be a sequence that satisfies the recurrence relation [tex]\rm a_n=a_{n-1}+3[/tex] for n = 1, 2, 3,... and suppose that [tex]\rm a_0=2[/tex].

According to the given data, the recurrence relation is given below:

[tex]\rm a_n=a_{n-1}+3[/tex]   --- (1)

Now, substitute the value of (n = 1) in the above expression.

[tex]\rm a_1=a_{1-1}+3[/tex]

[tex]\rm a_1=a_{0}+3[/tex]           (put [tex]\rm a_0=2[/tex])

[tex]\rm a_1=2+3[/tex]

[tex]\rm a_1=5[/tex]

Now, substitute the value of (n = 2) in the expression (1).

[tex]\rm a_2=a_{2-1}+3[/tex]

[tex]\rm a_2=a_{1}+3[/tex]           (put [tex]\rm a_1=5[/tex])

[tex]\rm a_2=5+3[/tex]

[tex]\rm a_2=8[/tex]

Now, substitute the value of (n = 3) in the expression (1).

[tex]\rm a_3=a_{3-1}+3[/tex]

[tex]\rm a_3=a_{2}+3[/tex]           (put [tex]\rm a_2=8[/tex])

[tex]\rm a_3=8+3[/tex]

[tex]\rm a_3=11[/tex]

Step-by-step explanation:

To find percentage on a discount like this all you have to do is multiply the pre-discount number by your discount percentage.

So all you have to do is:

15 x 0.20

which gives you an answer of 3.

Thus the post-discount amount is $3.

Answer:

Total amount pay after 3 week = $147.5

Step-by-step explanation:

Given:

Amount of loan taken = $125

Amount interest per $100 = $6 per week

Find:

Total amount pay after 3 week

Computation:

Amount of interest per week = 125[6/100]

Amount of interest per week = $7.5 per week

Amount of interest in three week = 3 x Amount of interest per week

Amount of interest in three week = 3 x 7.5

Amount of interest in three week = $22.5

Total amount pay after 3 week = Amount of loan taken + Amount of interest in three week

Total amount pay after 3 week = 125 + 22.5

Total amount pay after 3 week = $147.5

Step-by-step explanation:

$14.20

Answer:

An isosceles triangle has 2 equal sides. If the perimeter is 110 inches, and your base is 34 inches, subtract the base from the total perimeter. 110-34= 76. If 2 sides have to be equal, the total length of the 2 sides is 76 inches, divide the 2 lengths by 2 to get the measure of each side individually. 76÷2=38.

Hence, your answer is each of the equal sides of the plate equals 38 inches.

Answer:

a = 6

Step-by-step explanation:

Given:

[tex]-8 + \sqrt{5a-5} = -3[/tex]

Assuming that the goal is to solve for a, we should aim to isolate a using a backwards process.

First step: add 8 to both sides, resulting in:

[tex]\sqrt{5a-5} = 5[/tex]

Second step: Next we need to square both sides, getting us:

[tex]5a - 5 = 25[/tex]

Third step: We now can add 5 to get an isolated monomial:

[tex]5a = 30[/tex]

Fourth Step: Finally, divide by 5 to get:

[tex]a = 6[/tex]

Answer:

A

Step-by-step explanation:

Given

P(t) = 60 [tex](3)^{\frac{t}{2} }[/tex]

Then

P(1) = 60 × [tex]3^{\frac{1}{2} }[/tex] = 60[tex]\sqrt{3}[/tex]

P(2) = 60 × 3 = 180

P(3) = 60 × [tex]3^{\frac{3}{2} }[/tex] = 60 ×[tex]\sqrt{3^{3} }[/tex] = 60 × 3[tex]\sqrt{3}[/tex] = 180[tex]\sqrt{3}[/tex]

P(4) = 60 × 3² = 60 × 9 = 540

P(5) = 60 × [tex]3^{\frac{5}{2} }[/tex] = 60 × [tex]\sqrt{3^{5} }[/tex] = 60 × 9[tex]\sqrt{3}[/tex] = 540[tex]\sqrt{3}[/tex]

P(6) = 60 × 3³ = 60 × 27 = 1620

From these 6 results we see that

P(3) = 3 × P(1)

P(4) = 3 × P(2)

P(5) = 3 × P(3)

P(6) = 3 × P(4)
