Which graph shows a mixed-degree system with exactly one solution?

Mathematics
1 answer:
polet [3.4K]3 years ago
5 0

Answer : option D

we need to find out the graph shows a mixed-degree system with exactly one solution

The solution of two graphs will be the intersection of two graphs

In the first graph,

There is no intersection of both circles, So no solution

second graph,

The circle intersects the parabola at two point, so two solution for this graph

Third graph,

The circle and line does not intersects, so no solution

Fourth graph,

Both parabola intersects at one point, so one solution for this graph

So option D has exactly one solution

Mr. Flowers 23 1/4 of land. He is going to 1/3 the acreage. He will sell the rest as 1/2-acrea lots. How many lots will he have
loris [4]

Answer:

  B.  31

Step-by-step explanation:

The acreage Mr. Flowers intends to sell is 2/3 of his total, so is ...

  (2/3)(23 1/4) = (2/3)(93/4) = 31/2 . . . . acres

Divided by 1/2 (which is the size of a lot), we will get the number of lots this will make:

  (31/2)/(1/2) = 31/1 = 31

Mr. Flowers will have 31 lots for sale.

9. Water is added to two containers for 20 minutes. The equations below model the ounces of
Anit [1.1K]

Answer:

792 ounces

Step-by-step explanation:

At the time when the containers hold the same amount of water the value of y in the equations is the same,  so

\large 62x+48=-2x^2+80x+120

Solve the quadratic equation:

\large 62x+48=-2x^2+80x+120\Rightarrow 2x^2-80x-120+62x+48=0\\\\2x^2-18x-72=0\Rightarrow x=\frac{-(-18)\pm\sqrt{(-18)^2-4(2)(-72)}}{2*2}=\\\\=\frac{18\pm\sqrt{324+576}}{4}=\frac{18\pm\sqrt{900}}{4}=\frac{18\pm 30}{4}

Take only the positive solution since x is positive (minutes)

\large x=\frac{18+30}{4}=\frac{48}{4}=12

Now, compute the amount of water y by replacing x = 12 in any of the two equations, for example in container A which is easier to calculate

y = 62(12) + 48 = 792

The correct answer is then 792 ounces

The population of a city is increasing at a rate of 4% each year. In 2000, there were 236,000 people in the city. Write an expon
sukhopar [10]

Answer:

A = 236,000 (1+ 0.04)^9

335,902 people in 2009

Step-by-step explanation:

Hi, to answer this question we have to apply an exponential growth function:  

A = P (1 + r) t  

Where:  

p = original population (in 2000)

r = growing rate (decimal form) = 4/100 = 0.04

t= years  

A = population after t years  

Replacing with the values given:  

A = 236,000 (1+ 0.04) ^t

To find the population in 2009:

We have to calculate the number of years passed since 2000: (2009-2000 = 9 years =t)

Substituting t=9 in the function:

A = 236,000 (1+ 0.04)^9

A =335,902 people

Feel free to ask for more if needed or if you did not understand something.
