All you have to do is input the equation into the square root formula.

Step-by-step explanation:

Answer:

x =

2 , 8

Step-by-step explanation:

(x-5)² = (x-5)(x-5) = x*x + x*-5 - 5*x - 5*-5 = x² - 5x - 5x + 25

          = x² - 10x + 25

x² - 10x + 25 = 9

x² - 10x + 25 - 9 = 0

x² - 10x + 16 = 0

x = {-(-10)±√((-10)²-(4*1*16))} / (2*1)

x = {10±√(100-64)} / 2

x = {10±√36} / 2

x = {10±6} / 2

x₁ = {10-6} / 2 = 4/2 = 2

x₂ = {10+6} / 2 = 16/2 = 8

Check:

x₁

(2-5)² = 9

-3² = 9

x₂

(8-5)² = 9

3² = 9

Answer:

His new income is $26,910.

Step-by-step explanation:

As Regi has received an increase in his annual salary that has represented $ 910 in his payment, to determine his new salary the following calculation must be performed:

910 / 3.5 = 1% salary

260 = 1% salary

260 x 100 = previous salary

26,000 = previous salary

26,000 + 910 = current salary

26,910 = current salary

Therefore, his new income is $26,910.

Complete Question

(7.006 x 10⁴¹) x (5.09 x 10²²)

OA) 3.566 x 10⁴¹

OB) 3.566 x 10⁶²

ОС) 3.566 x 10⁶³

OD)3.566 x 10⁶⁴

Answer:

D. 3.566 × 10⁶⁴

Step-by-step explanation:

We are asked to solve:

(7.006 x 10⁴¹) x (5.09 x 10²²)

When we multiply this together

= (7.006 × 5.09 ) × 10(⁴¹+²²)

= (7.006 × 5.09 ) × 10⁶³

= 35.66054 × 10⁶³

= 3.566054 ×10⁶⁴

Approximately = 3.566 × 10⁶⁴

The two square roots of 9/4 is  [tex]3/2[/tex].

It is required to find the two square roots of 9/4.

A factor of a number that, when multiplied by itself, gives the original number. The square root of any number can be expressed using the formula: √y = y½.

Solution:

Using the principal square root:

[tex]\sqrt{9/4} \\\\=3/2[/tex]  and [tex]3/2[/tex].

Hence, the two square roots of 9/4 is  [tex]3/2[/tex].

Answer:

Step-by-step explanation:

Answer:

[tex]x_{18}=387420489[/tex]

Step-by-step explanation:

So we have the sequence:

3, 9, 27...

First, note that this is a geometric sequence because each subsequent term not increasing linearly.

To find the 18th term, we can write an explicit formula.

The standard explicit formula for a geometric sequence is:

[tex]x_n=a(r)^{n-1}[/tex]

Where a is the initial term, r is the common ratio, and n is the nth term.

From the sequence, we can see that the initial term a is 3. The common ratio is 3 since each subsequent term is 3 times the previous term. So, substitute:

[tex]x_n=3(3)^{n-1}[/tex]

To find the 18th term, substitute 18 for n. So:

[tex]x_{18}=3(3)^{18-1}[/tex]

Subtract:

[tex]x_{18}=3(3)^{17}[/tex]

Evaluate:

[tex]x_{18}=3(129140163)[/tex]

Multiply:

[tex]x_{18}=387420489[/tex]

Answer:

  14.25 yd^2

Step-by-step explanation:

The triangle area is given by the formula ...

  A = 1/2bh

Here, the base is 10 yd, and the height is 5 yd, so ...

  triangle area = (1/2)(10 yd)(5 yd) = (5 yd)^2 = 25 yd^2

__

The semicircle is half the area of a circle with radius 5 yd, so its area is ...

  semicircle area = (1/2)π(5 yd)^2 = 12.5π yd^2 ≈ 39.25 yd^2

__

The shaded region is the difference between these areas:

  shaded area = 39.25 yd^2 -25 yd^2 = 14.25 yd^2

Answer:

-1opw+9p^2q+5q^2

Step-by-step explanation:

First find the height of the cylinder:

15.2 -0.5 = 14.7

The formula for a circle is : V= [tex]\pi r^{2}[/tex] h

V= [tex]\pi (5.4)^{2} (14.7)[/tex] (substitute pi for 3.14)

V= (3.14) (5.4)² (14.7) simplfy

V= 1345.96728
