Answers

Answer 1

Answer:

84

Step-by-step explanation:

women=x

daughter=y.

x=2y.

x-21=3(y-21).

2y-21=3y-63.

42=y.

x=84.

Hope this helps plz hit the crown :D

Answer 2

Answer:

Daughter's present age = 42 years

Women's present age =  84 years

Step-by-step explanation:

Daughter's present age = x years

Women's present age = 2*x = 2x

21 years ago:

Daughter's age = x - 21

Women's age = 2x - 21

Women's age = 3*daughter'sage

2x - 21 = 3*(x - 21)

2x - 21 = 3x - 63        {Subtract '2x' from both sides}

   - 21   = 3x - 2x - 63

   -21    = x - 63             {Add 63 to both sides}

-21 +63 =  x

42  = x

Daughter's present age = 42 years

Women's present age = 2*42 = 84 years

D: All real numbers except x=-1 and x=1

Step-by-step explanation:

Step-by-step explanation:

The domain of the rational expression is when the denominator is defined. (non-zero)

When the denominator is 0,

4x² - 4 = 0.

=> x² - 1 = 0, (x + 1)(x - 1) = 0, x = -1 or x = 1.

Hence the answer is all real numbers except x = -1 and x = 1.

(x - 1) is a factor of the following, what are the remaining 2 factors:

Answers

Answer:

(x +(-2) ) and ( x+3)

The factors of a given cubic polynomial function are

( x-1) (x -2 ) and (x +3)

Step-by-step explanation:

Step(i):-

Given that  x³ - 7x + 6=0

        f(x) =  x³ - 7x + 6=0

put x=1

       f(1) = 1 -7 +6 =0

(x -1 ) is one factor of given polynomial

By using synthetic division

                  x³     x²        x      constant

x=1          ║ 1      0        -7          6

              ║  0      1          1        -6

                1       1         -6         0

The polynomial   ( x² + x - 6) =0

Step(ii):-

The factors of

               x² + x - 6=0

              x² + 3x -2x - 6=0

             x ( x +3 ) - 2( x +3) =0

            (x -2 ) ( x+3 ) =0

            x = 2 and x =-3

Final answer:-

The factors of a given cubic polynomial function are

( x-1) (x -2 ) and (x +3)

The correct answer is an option (D)

What is polynomial?

"A mathematical expression which is composed of variables, constants and exponents, that are combined using the mathematical operations."

What is long division?

"It is a method for dividing one large degree polynomial number into smaller degree polynomials."

What is quotient?

"It is the result of the division of a polynomial by any other polynomial."

For given question,

We have been given polynomials [tex]3x^4 + 20x^3 + 14x^2 + 17x + 30[/tex] and [tex]x+6[/tex]

We need to find the quotient when [tex]3x^4 + 20x^3 + 14x^2 + 17x + 30[/tex] is divided by x + 6.

Using long division the division of  [tex]3x^4 + 20x^3 + 14x^2 + 17x + 30[/tex] and [tex]x+6[/tex] is shown below.

Therefore, the quotient is [tex]3x^3+2x^2+2x+5[/tex]

Ailani draws a map of her local town. She places the town hall at the origin of a coordinate plane and represents a lake
with a circle drawn on the map. The center of the lake is 19 miles east and 3 miles south of the town hall, and the
radius of the lake is 0.5 miles.
If the positive x-axis represents east and the positive y-axis represents north, which equation represents the lake?
O (x + 19)2 + (y - 3)2 = 0.5
O (x – 19)2 + (y + 3)2 = 0.5
O (x + 19)2 + y - 3)2 = 0.25
O (x - 19)2 + ( + 3)2 = 0.25

Answers

The equation of the lake with a center 19 miles east and 3 miles south with radius of 0.5 miles is (x + 19)² + (y + 3)² = 0.25

What is an equation?

An equation is an expression that shows the relationship between two or more variables and numbers.

The equation for a circle is given as:

(x - h)² + (y - k)² = r²

Where (h, k) is the center of the circle and r is the radius.

The center of the lake is 19 miles east and 3 miles south, i.e. (-19, -3) and the radius is 0.5 miles.

The equation of the lake is:

(x - (-19))² + (y - (-3))² = 0.5²

(x + 19)² + (y + 3)² = 0.25

The equation of the lake with a center 19 miles east and 3 miles south with radius of 0.5 miles is (x + 19)² + (y + 3)² = 0.25

Answer: D.  [tex](x-19)^2+(y+3)^2=0.25[/tex]

Step-by-step explanation:

Let's review what we know:

the lake is circularthe town hall is at the originthe center of the lake is 19 miles east of the origin and3 miles south of itthe radius of the lake is 0.5 miles

A circle can be depicted on the coordinate plane with the equation [tex](x-h)^2+(y-k)=r^2[/tex], where:

(h, k) is the center of the circleand r is the radius of the circle

19 miles east of the origin would be 19 units to the right of the origin on the coordinate plane, as east is the rightwards direction in real life. In short, h = 19.

Let's plug in that value: [tex](x-(19))^2+(y-k)^2=r^2[/tex].

So we know that the x-coordinate defining part of the equation would have to be [tex](x-19)^2[/tex].

Meanwhile, 3 miles south of the origin would be modeled as three units underneath it, because south would be considered "downwards". The y-value (k) would be negative 3.

Putting what we have so far together, the center of the circle would be (19, -3).

Therefore, the y-coordinate defining part of the equation would be [tex](y+3)^2[/tex].

Here's what the equation looks like with the work we've completed so far: [tex](x-19)^2+(y+3)^2=r^2[/tex]

Finally, let's plug in the radius value 0.5.

0.5 * 0.5 = 0.25

Ailani would use the equation [tex](x-19)^2+(y+3)^2=0.25[/tex] to model the lake in relation to the town hall. I hope that makes sense!
