Find the 97th of the arithmetic sequence 25, 29, 33, ...

Answer:

A = x^2 - x + xy - y

P = 4x + 2y - 2

Step-by-step explanation:

[tex]a = (x + y)(x - 1) \\ a = {x}^{2} - x + xy - y \\ \\ p = 2((x + y) + (x - 1)) \\ p = 2(2x + y + - 1) \\ p = 4x + 2y - 2[/tex]

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)

Answer:

(1) Conjugate = -i8

(2) Conjugate = -i3+9

(3) Conjugate = i2+1

(4) Conjugate = -3-iy

Step-by-step explanation:

From the question,

Conjugate of a surd is formed by changing the sign between a rational number and a surd in an expression.

The conjugate of a surd is obtained by changing the sign of the surd in the expression.

Given

(1) i3+i5 = i8

Conjugate is -i8

(2) i3+9

Conjugate is -i3+9

(3) -i2+1

Conjugate is i2+1

(4) -3+iy

Conjugate is -3-iy

Step-by-step explanation:

x/4 - 9 = -1

×/4 = -1 + 9

x/4 = 8

4 (x/4) = 4 (8)

x = 32

Answer:

32

Step-by-step explanation:

(Quotient of a and b = a/b)

Let the number = x

Quotient of the number and four: x/4

9 subtracted from the quotient of the number and four: x/4 - 9

-1 is the result of 9 subtracted from the quotient of the number and four: x/4 - 9 = -1

x/4 -9 = -1

x/4 = 8

x = 32

Answer:

5 customers

Step-by-step explanation:

If she takes 1 hour to trim and 1 hour to style, she will take 2 hours per customer.

She plans to work 3 hours a day. So, she can only fit 1 customer in per day because if she scheduled 2 she would need at least 4 hours.

If she can only have 1 customer per day over a 5 day week she will only be able to schedule 5 customers per week.

Answer:

5 sides

Step-by-step explanation:

A polygon includes the shape pentagon which has  5 sides.

If  n  are number of sides of a convex polygon, sum of its interior angles is 540 degrees.

As in given case sum of interior angles is 540°, we have

( n  −  2 )  ×  180 °  =  540°

When we solve this equation, we get 5 sides.

We can check this by plugging 5 into n, so the equation is

(5 - 2) x 180°   = 540, this becomes...

3 x 180 = 540; this is correct so you answer is 5 sides.

Answer:

for 9^(x)-1=2 the answer is 1/2 or .5

The solution to this equation 9ˣ - 1 = 2 is 1/2.

The correct option is A.

Two algebraic expressions having same value and symbol '=' in between are called as an equation.

Given:

An equation:

9ˣ - 1 = 2

Simplifying,

9ˣ  = 3

3²ˣ = 3

Comparing, we get,

2x = 1

x = 1/2

Therefore, the solution is x = 1/2.

4, It is the height of triangle ABC

Step-by-step explanation:

The easy way is to just count. But you can also use the Pythagorean theorem because BDC is a right triangle. First, use the distance formula to find BC. [tex]\sqrt{(5-2)^{2} +(-2-2)^2[/tex]=5

5^2=BD^2+DC^2

25=BD^2+9

BD=4

[tex]BD = \sqrt{89}[/tex],BD is the median of ∆ABC. A median is a line segment that joins a vertex of a triangle to the midpoint of the opposite side. In ∆ABC, BD divides the triangle into two smaller triangles that are congruent.

The length of BD can be calculated using the Pythagorean Theorem. The Pythagorean Theorem states that in a right triangle, the square of the hypotenuse is equal to the sum of the squares of the other two sides.

In the triangle shown, the hypotenuse is BD, and the other two sides are AB and BC. So, we can use the Pythagorean Theorem to write the equation:

BD² = AB² + BC²

We are given that AB = 5 and BC = 8. So, we can plug these values into the equation to get:

BD² = 5² + 8² = 25 + 64 = 89

Taking the square root of both sides, we get:

[tex]BD = \sqrt{89}[/tex]
