Find the value of f(5) y = f(x) on a graph

Answer:

because 4 is being multiplied by 500 which has two zeros because it is a multiple of 100

Step-by-step explanation:

Answer:

Because when you multiply 500 by 4 you start with the first 0. 4x0 is 0, now you move on to the second 0. 4x0 is 0, so that one is 0 too. Now you multiply the 5. 5x4 is 20. You put the 20 first, followed by the two 0s, And you get 2,000.

Answer:

slope: -1/2

y-int: 9/2

Step-by-step explanation:

rearrange 9-x=2y into slope-intercept form: y=mx+b (m being slope and b is y-intercept)

2y = -x + 9

divide both sides by 2 to isolate the y and get:

y = -x/2 + 9/2

m (slope) = -(1)/2

b (y-int) = 9/2

Now suppose that x1,y1 , x2,y2 , , xn,yn are the vertices of a polygon (with positive orientation). The area of the polygon is A 1 2 C xdy ydx 1 2 x1y2 x2y1 x2y3 x3y2 xny1 x1yn . The problem asks us to find the area of the pentagon with vertices 0,0 , 2,1 , 1,3 , 0,2 , and 1,1 .

Step-by-step explanation:

The area of the given triangle JKL is 16 units square.

A triangle is a 3-sided shape that is occasionally referred to as a triangle. There are three sides and three angles in every triangle, some of which may be the same.

The sum of all three angles inside a triangle will be 180° and the area of a triangle is given as (1/2) × base × height.

Given vertices form a triangle in the coordinate plane ;

Base = 3 + 5 = 8 units

Height = 9 - 5 = 4 units.

Since the area of a triangle is given as (1/2) × base × height.

So,

Area = (1/2) × 8 × 4 = 16 unit square.

Hence "The area of the given triangle JKL is 16 units square".

Option second [tex]\rm (w-2.5)(w+2.5)[/tex] and option fourth  [tex]\rm (-4v-9)(-4v+9)[/tex]  are the products that result in a difference in squares.

It is required to identify which products result in a difference in squares.

Polynomial is the combination of variables and constants in a systematic manner with "n" number of power in ascending or descending order.

We know that:

[tex]\rm (a^2-b^2)=(a+b)(a-b)[/tex]

In option first:

[tex]\rm = (5z+3)(-5z-3)\\\rm = -(5z+3)(5z+3)\\\rm = -(5z+ 3)^2[/tex]

Which is not the difference between squares.

In option second:

[tex]\rm=(w-2.5)(w+2.5)\\\rm =(w^2-2.5^2)[/tex]By using [tex]\rm (a^2-b^2)=(a+b)(a-b)[/tex]

It is the difference between squares.

Similarly, in option third:

[tex]\rm =(8g+1)(8g+1)\\\rm =(8g+1)^2[/tex]

It is not the difference between squares.

Similarly, in option forth:

[tex]\rm = (-4v-9)(-4v+9)\\\rm = (4v+9)(4v-9)\\\rm = (4v)^2-9^2[/tex]

It is the difference between squares.

Similarly, in option fifth:

[tex]\rm = (6y+7)(7y-6)\\\rm = 42y^2+13y-42[/tex]

It is not the difference between squares.

Similarly, in option sixth:

[tex]\rm =(p-5)(p-5)\\\rm =(p-5)^2[/tex]

It is also not the difference between squares.

Thus, option second and option fourth are correct.

Answer:

Step-by-step explanation:

Yes

Answer:

N + B + D = 90     sum of ages is 90        (I)

B = 2 D     B is twice as old as D

N + 3 D = 90      using above equations

(N + 10) + 3 D = 100        add 10 to both sides

B + 3 D = 100             Brian is 10 yrs older than Nigel

2 D + 3 D = 100       Brian is twice the age of Dean

5 D = 100      

D = 20      Dean's age

Brian = 2 D = 40 Brian's age

90 - 60 = 30 = Nigel's age

Check:

N + 10 = B = 30 + 10 = 40 = Brian's age

The quadratic polynomial 6x² – 7x + 2 has factors (3x – 2) and (2x – 1). Then the correct option is A.

It is the method to separate the polynomial into parts and the parts will be in multiplication. And the value of the polynomial at this point will be zero.

The quadratic polynomial is 6x² – 7x + 2.

On factorization, we have

6x² – 7x + 2

6x² – (4 + 3)x + 2

6x² – 4x – 3x + 2

2x(3x – 2) –1(3x – 2)

(3x – 2)(2x – 1)

The factor is (3x – 2).

Answer:

the probability that both dessert and drink are sugar free = ¼

Step-by-step explanation:

We are told that there are 5 different sandwiches, 4 different desserts and 6 different drinks.

Now, since Two of the four desserts are sugar free, then the probability that the dessert chosen is sugar free is;

P(desert sugar free) = ½

Now, three of the the 6 drinks are sugar free, then the probability that the drink chosen is sugar free is;

P(drink sugar free) = 3/6 = ½

Thus, the probability that both dessert and drink are sugar free is;

P(both sugar free) = ½ × ½ = ¼

Answer:

A. Total area of Alaska is considerable larger than total area of Connecticut.

B. Population of California is considerably larger that population of Alaska.

Step-by-step explanation:

A. What is the difference in total area of Alaska and Connecticut?

According to the US government, total areas of Alaska and Connecticut are 663,268 square miles ([tex]6.633\times 10^{5}[/tex] square miles) and 5,567 square miles ([tex]5.567\times 10^{3}[/tex] square miles), respectively.

The difference between both quantities is:

[tex]x = 6.633\times 10^{5}\,mi^{2}-5.567\times 10^{3}\,mi^{2}[/tex]

[tex]x = 6.577\times 10^{5}\,mi^{2}[/tex]

Which means that total area of Alaska is considerable larger than total area of Connecticut.

B. What is the difference in total population of California and Alaska?

According to the US government, total populations of California and Alaska are 39,512,223 people ([tex]3.951\times 10^{7}[/tex] people) and 710,249 people ([tex]7.103\times 10^{5}[/tex] people), respectively.

The difference between both quantities is:

[tex]x = 3.951\times 10^{7}\,people - 7.103\times 10^{5}\,people[/tex]

[tex]x = 3.880\times 10^{7}\,people[/tex]

Which means that population of California is considerably larger that population of Alaska.
