My father is 42 years old as obtained from the cubic polynomial's real root.

We know that if x = a is one of the roots of a given polynomial x - a = 0 is a factor of the given polynomial.

To confirm if x - a = 0 is a factor of a polynomial we replace f(x) with f(a) and if the remainder is zero then it is confirmed that x - a = 0 is a factor.

let my age be x years.

So, My mother is (x + 25) and my father is (x + 28) years.

∴ {x(x + 25)(x + 28) = 32130.

(x² + 25x)(x + 28) = 32130.

x³ + 53x² + 700x = 32130.

x³ + 53x² + 700x - 32130 = 0.

Now solving this has only one real solution x = 17.

So, My father is (17 + 25) = 42 years old.

Answer:

Radius = 6 ft

Diameter = 12 ft

Circumference = 37.7 ft

Step-by-step explanation:

The radius of the circle is the measurement from the center of the circle to the edge. The diagram gives us the radius, 6 ft.

Radius = 6 ft

The diameter of the circle is the measurement from the edge of the circle through the center, extending back to the edge. The diameter is equal to double the radius.

6*2=12

Diameter = 12 ft

The circumference of the circle is the distance around its edge or the perimeter of the circle. We use the below equation to solve for it:

[tex]C=\pi d[/tex] where [tex]d[/tex] is the diameter

Plug the diameter (12) into the equation

[tex]C=\pi (12)\\C=37.7[/tex]

(This answer is approximate)

Circumference = 37.7 ft

Answer:

0.387

Step-by-step explanation:

Answer:

The answer would be 0.387

Step-by-step explanation:

Let xy = k, where k is the constant of variation.

By using values of x and y in the table,

we see that (2)(48) = (4)(24) = (12)(8) = 96.

Hence k = 96, which is our answer.

Answer: ‭$54.75

Step-by-step explanation:

The price the shoes are sold to the warehouse is:

= 24 * ( 1 + 15%)

= 24 * 1.15

= $27.60

The price the warehouse sells it is:

= 27.60 + 10

= $37.60

Price distributor sells is:

= 37.60 * 1.12

= $42.112

Fine shoes will then sell at 30% profit:

= 42.112 * 1.3

= $‭54.7456‬

= ‭$54.75

Answer:

5/2

Step-by-step explanation:

Answer:

5/2 is the largest fraction.

Step-by-step explanation:

To find the largest fraction, we can convert some using the LCD (least common denominator)

Keep 5/6 as is.

1/3 = 2/6

3/2 = 9/6

5/2 = 15/6

So, 5/2 is the largest fraction.

Answer:

30% are children.

Step-by-step explanation:

Females = 30%

Males = 40%

Therefore, children = 100% (total) - 30% + 40%

100 - 70

30%

in a city 30 °/• are female and 40°/. are males . what are remaining children?

Given,

▶️ percentage of females = 30%

▶️ percentage of males = 40%

▶️ let the percentage of children be x.

Now,

▶️ x = 100% (total population) - 30% + 40%

▶️ x = 100% - 70%

▶️ x = 30% (Children population)

The population % of children in a city is 30%.

Answer:

Step-by-step explanation:

(x + 2) ÷ 2 + (x + 4) ÷ 4 = 4

lcm is 6

(x + 2) ÷ 2 × 6 + (x + 4) ÷ 3 × 6 = 4

(x + 2) × 3 + ( x + 4) × 2 = 4

3x + 6 + 2x + 8 = 4

correct like terms

3x + 2x + 6 + 8 = 4

5x + 14 = 4

5x + 14 - 14 = 4 - 14

5x = - 10

5x ÷ 5 = -10 ÷ 5

Answer:

B

Step-by-step explanation:

It's a little hard to see but I'm pretty sure it's B because we're looking for a graph that has a slope of -2 so it couldn't be A or D because they have positive slopes since they are pointing up. That leaves B and C. I can't really see but C doesn't look like it has a slope of -2, so I went with B because it has a y-intercept of 3 and looks like it has a slope of -2.

Answer:

y coordinate = 13

x coordinate = -1

Step-by-step explanation:

Trail and error lol

The missing [x] - coordinate of point A is -2 and point B is -1.

The general equation of a straight line is -

[y] = [m]x + [c]

where -

[m] → is slope of line which tells the unit rate of change of [y] with respect to [x].

[c] → is the y - intercept i.e. the point where the graph cuts the [y] axis.

We have the equation of line as -

y = 3x + 7

Refer to the graph attached of the equation -

y = 3x + 7.

Since, the graph is not given we will mark two random points on it. It can be seen that the missing [x] - coordinate of point A is -2 and point B is -1.

Therefore, the missing [x] - coordinate of point A is -2 and point B is -1.
