If two people can plough a field in six hours, it would take one person 12 hours. 6x2=12

If x = 36 when y = 40 and x varies directly as y, what is x when y = 80?

Since y = 80, 80/40 = 2 so 36 x 2 = 72

x = 72

x = 72

g(x) is a polynomial that has a leading coefficient of 3, and the following roots -1,1,2. Write g(x) in standard form

The **standard form **of the **polynomial **is written as:

p(x) = 3*x^3 - 6*x^2 - 3x + 6

How to write the polynomial in standard form?We know that a **polynomial **of degree N is with the zeros {x₁, x₂, ...} and a **leading coefficient** a can be written as:

p(x) = a*(x - x₁)*(x - x₂)*...*(x - xₙ)

In this case, we know that the **leading coefficient** is 3, and the zeros of the **polynomial **are {-1, 1, 2}

Then we can write:

p(x) = 3*(x + 1)*(x - 1)*(x - 2)

Now we need to expand that, we will get:

p(x) = 3*(x + 1)*(x - 1)*(x - 2)

p(x) = 3*(x^2 + 1*x + x*(-1) + 1*(-1))*(x - 2)

p(x) = 3*(x^2 - 1)*(x - 2)

p(x) = 3*(x^3 + x^2*(-2) - x + 2)

p(x) = 3*x^3 - 6*x^2 - 3x + 6

That is the **polynomial **in **standard form.**

The hypotenuse of a right triangle is 30 inches. With one of the sides being 18 inches. Find the missing side length. Round to the nearest hundredth if necessary

**Answer:**

24 inches

**Step-by-step explanation:**

We can find different sides of a right angle triangle using Pythagorean theorem: [tex]c^2 = a^2+b^2[/tex], where [tex]c[/tex] is the hypotenuse and [tex]a[/tex] and [tex]b[/tex] are the other sides.

Therefore, we can re-arrange the equation for one of the other sides.

[tex]c^2-b^2=a^2[/tex].

Since we know these two sides all we have to do is put them into the equation:

[tex](30)^2-(18)^2=a^2[/tex]

[tex]a^2 = 576\\a= 24[/tex]

Therefore, the missing side is 24 inches.

Explain what happens as the heart grows bigger.

**Answer:**

An enlarged left ventricle, one of the most serious types of enlarged heart, increases the risk of heart failure. In heart failure, your heart muscle weakens, and the ventricles stretch (dilate) to the point that the heart can't pump blood efficiently throughout your body.

The diagram shows a triangle.

What is the value of z?

**Answer:**

z=31°

**Step-by-step explanation:**

32°+117°+z=180°{ sum of angle of triangle}

z=180-149

z=31°

stay safe healthy and happy.**Answer:**

31 degrees = x

**Step-by-step explanation:**

a triangle's sum is 180 degrees

let's form an equation that allows us to work backwards and find this

add the other two angle measures to x and let the sum be 180

32+117+x=180

31 is the difference and therefore the missing angle measure

Find the length of ST. Round your answer to the nearest tenth of an inch.

**Answer:**

7.1

**Step-by-step explanation:**

Once again we can use trig ratios to solve for ST

First we must recall the trig function

Sin = Opposite over Hypotenuse

Cos = Adjacent over Hypotenuse

Tan = Opposite over Adjacent

We are given the measure of an angle and the length of the hypotenuse

Of the given angle we need to find the adjacent side length

When working with the hypotenuse and adjacent we use trig function cosine

That being said we want to create an equation ( remember cos = adjacent over hypotenuse ) ( let ST = x)

[tex]cos(42)=\frac{x}{9.5}[/tex]

now we solve for x

Step 1 multiply each side by 9.5

[tex]cos(42)*9.5=9.5cos(42)=7.059875842\\\frac{x}{9.5} *9.5=x[/tex]

we're left with x = 7.059875842

Finally we round to the nearest tenth and get that the answer is 7.1

Select the correct answer.

The given table shows the number of customers, c(x), in a diner when the diner has been open for x minutes.

x 30 45 60 75 90 105

c(x) 40 48 50 48 40 30

Which statement is supported by the table?

The number of customers in the diner is increasing on the interval (30,60).

The maximum number of customers in the diner is 60.

The number of customers in the diner is increasing on the interval (75,105).

The maximum number of customers in the diner is 105.

The first statement is true Bc the number of customers are increasing between 30min and 60 min

The Max number would be 50 customers not 60. It would’ve been true if it changed it to max number of customers was at 60 mins

The Max number would be 50 customers not 60. It would’ve been true if it changed it to max number of customers was at 60 mins

1. Are the two expressions below

equivalent

25x + 20y = 5x(5+4y)

**Answer:**

No.

**Step-by-step explanation:**

25x + 20y = 5x(5 + 4y)

Distribute the 5x inside the (5 + 4y).

5x * 5 = 25x

5x * 4y = 20xy

25x + 20y ≠ 25 + 20xy, so the two expressions below are not equal.

3. My sister is 12 years older than lam Our combined age is half the age of our

grandfather. Our grandfather is 68 years old. How old am

**Answer:**

11

**Step-by-step explanation:**

First, write an equation to represent the situation.

34 = 2a + 12

This equation works because your combined age is half of 68, so 34. If your age is a, then yours sister's age is a + 12. if you add your age to your sister's, you get 2a + 12.

Now just solve for a.

34 = 2a + 12

First, subtract 12 from both sides.

22 = 2a

Then divide both sides by 2.

11 = a

So you are 11 years old. If you need to check your work, your age (11) plus your sister's age (11 + 12, which is 23) is 34, which is half of your grandfather's age.

The sum of 85 + w is less than or equal to 6 multiplied by y.

A. 85 + w ≤ 6y

B. 85 + w ≥ 6y

C. 6 x y ≤ 85 + w

D. 85 + w ≠ 6y

**Given:**

The sum of 85 + w is less than or equal to 6 multiplied by y.

**To find:**

The inequality for the given situation.

**Solution:**

We know that,

The sum of 85 and w means "85+w".

Less than or equal means "≤".

6 multiplied by y means "6y".

So, the inequality for the statement "the sum of 85 + w is less than or equal to 6 multiplied by y", is:

[tex]85+w\leq 6y[/tex]

**Therefore, the correct option is A.**

one isotope of chromium has a half life of 18 hours. How long does it take 100 grams to decay to 20 grams?

**Answer:**

41.79 hours

**Step-by-step explanation:**

The Half-time Decay Formula: [tex]N=N_0(\frac{1}{2})^\frac{t}{d}[/tex]

Where [tex]N_0[/tex] is the original number, and t = time, and d = time it takes to half

18 would be d

100 would be [tex]N_0[/tex]

and 20 would be N

[tex]20=100(\frac{1}{2})^\frac{t}{18}[/tex]

[tex]0.2=(\frac{1}{2})^\frac{t}{18}[/tex]

[tex]log_\frac{1}{2}0.2=\frac{t}{18}[/tex]

[tex]18* log_\frac{1}{2}0.2=t[/tex]

[tex]18* \frac{log_{10}0.2}{log_{10}\frac{1}{2}}=t[/tex]

= 41.79470571
