What compound inequality describes this graph

Answer:

No

Step-by-step explanation:

Let's define our 2 terms first.

2x³y

2xy²

We see here that one term has a x³y and the other has a xy² term. Since they are not the same, the 2 terms are not like terms.

Answer:

The answer is 1,200 in. tall

Step-by-step explanation:

Because you just need to multiply length times width so the length would be 40 in. and width would be 30 in. so 40 x 30=    1,200 in.

Answer:

f(3) = 15. Correct: D)

Explanation:

Numeric Value of a Function

The value of a function f(x) when x = a is calculated by replacing the x for a. We have the function:

[tex]f(x)=x^2+5x-9[/tex]

It is required to find f(3), or the numeric value of f when x=3. Replace x for 3

[tex]f(3)=3^2+5(3)-9[/tex]

[tex]f(3)=9+15-9[/tex]

[tex]f(3)=15[/tex]

A) Incorrect. f(3) is not 7

B) Incorrect. f(3) is not 10

C) Incorrect. f(3) is not 9

D) Correct. f(3) =15 as found above.

Step-by-step explanation:

4(px + 1) = 64

Step 1: Add -4 to both sides.

4px + 4 -4 = 64 + -4

4px = 60

Step 2: Divide both sides by 4p.

4px = 60

4p 4p

Answer:

t = 4.2 h

Step-by-step explanation:

We can calculate the time taken by the car to travel 400 miles, easily by taking a difference of time in graph between 0 miles and 400 miles value:

t₄₀₀ = 3.5 h - 0 h

t₄₀₀ = 3.5 h

Now, we calculate the constant speed of the car from the following formula:

s = vt

v = s/t

where,

v = velocity of the car = ?

s = distance covered by the car = 400 mi

t = time taken = 3.5 h

Therefore,

v = 400 mi/3.5 h

v = 114.28 mi/h

Now, for this uniform speed the time taken to cover the distance of 480 miles will be:

114.28 mi/h = 480 mi/t

t = (480 mi)/(114.28 mi/h)

t = 4.2 h

Answer:

  100 square inches

Step-by-step explanation:

The width of the shelf is BC = 20 - 10 = 10 inches.

The height of the shelf is AB = 30 - 10 = 20 inches.

The area of a triangle with these dimensions is ...

  A = (1/2)bh

  A = (1/2)(10 in)(20 in) = 100 in^2

The area of the shelf is 100 square inches.

Answer:

The answer is

C. The mapping represents y as a function of x, because each x-value corresponds to exactly one y-value.

Step-by-step explanation:

In mathematics, mapping is used synonymously to a function, and a function is basically a relation between two values or expressions say y and x

like the difference equation relating y and x.

In a function, for every value of x plugged into the function there is always a corresponding value of y.

Example.

Given the function

y=2x+5.

find the value of y when x=0

we are going to substitute x=0 and solve

y=2(0)+5

y=5

so for x=0 y=5

Answer:

Step-by-step explanation:

To find the time taken for an object to travel given it's velocity and distance covered we use the formula

[tex]time = \frac{distance}{speed} \\ [/tex]

From the question

distance = 480 miles

speed = 40 mi/h

So we have

[tex]time = \frac{480}{40} = \frac{48}{4} \\ [/tex]

We have the final answer as

Answer:

Cheryl's age = x = 7 years

Rita's age = y = 17 years

Step-by-step explanation:

Let

Cheryl's age = x

Rita's age = y

Two years ago, Rita was three times older than Cheryl

(y - 2) = 3(x - 2)

y - 2 = 3x - 6

y = 3x - 6 + 2

= 3x - 4

y = 3x - 4

In 3 years, Rita will be twice older than Cheryl

(y + 3) = 2(x + 3)

y + 3 = 2x + 6

y = 2x + 6 - 3

= 2x + 3

y = 2x + 3

Equate both equations

3x - 4 = 2x + 3

Collect like terms

3x - 2x = 3 + 4

x = 7 years

Substitute x = 7 into

y = 2x + 3

= 2(7) + 3

= 14 + 3

= 17

y = 17 years

Cheryl's age = x = 7 years

Rita's age = y = 17 years

Answer:

The amount of Polonium-210 left in his body after 72 days is 6.937 μg.

Step-by-step explanation:

The decay rate of Polonium-210 is the following:

[tex] N(t) = N_{0}e^{-\lambda t} [/tex]     (1)

Where:

N(t) is the quantity of Po-210 at time t =?

N₀ is the initial quantity of Po-210 = 10 μg

λ is the decay constant  

t is the time = 72 d  

The decay rate is 0.502%, hence the quantity that still remains in Alexander is 99.498%.    

First, we need to find the decay constant:

[tex] \lambda = \frac{ln(2)}{t_{1/2}} [/tex]    (2)

Where t(1/2) is the half-life of Po-210 = 138.376 days

By entering equation (2) into (1) we have:

[tex] N(t) = N_{0}e^{-\frac{ln(2)}{t_{1/2}}*t}} = 10* \frac{99.498}{100}*e^{-\frac{ln(2)}{138.376}*72} = 6.937 \mu g [/tex]    

Therefore, the amount of Polonium-210 left in his body after 72 days is 6.937 μg.  

I hope it helps you!  

Answer:

$304.63

Step-by-step explanation:

From the information provided, the total cost can be calculated by multiplying the price of each item for the amount purchased and adding up the results:

Total cost=($87.98*2)+($14.57*3)+($21.24*4)

Total cost=$175.96+$43.71+$84.96

Total cost= $304.63

According to this, the answer is that their total cost is $304.63.

Answer:

3/4 ÷ 1/2 is one and one half or 3/2

Answer:

1.5 or 1 1/2

Step-by-step explanation:

3/4 divided by 1/2 is simply a reverse order of multiplication.

As you see if you swap the 1 and 2 in one half you get 2 over 1.

This changes the division sign to a multiplication sign.

Thus then you can multiply 3/4 by 2 to get 6/4.

6/4 then can be simplified as 1 and 1/2 or 1.5.
