Answer:

20 mile

Step-by-step explanation:

One inch is equivalent to 10 miles. Given this comparison in regards to scale, 2 inches would simply be 2 times that. In basic terms, 2 times or inches multiplied by each 10 mile increment would be stated as 2 inches x 10 miles, resulting in a 20 mile distance between the two cities.

The discriminant of the quadratic equation 2x + 5x2 = 1 is 24.

You get 24

Answer:

24

Step-by-step explanation:

Discriminant

b² - 4ac   (when ax² + bx + c = 0)

Assuming the given equation is:   2x + 5x² = 1

Rewrite the equation so that it equals zero:

⇒ 5x² + 2x - 1 = 0

Therefore,  a = 5    b = 2    c = -1

Input these into the discriminant formula and solve:

⇒ 2² - 4(5)(-1) = 4 + 20

                      = 24

Therefore, the discriminant of the quadratice equation is 24.

Answer: A

Step-by-step explanation:

x^2 - 3x + 5 = 0 - quadratic equation

Standard quadratic equation form: a^2 + bx + c = 0

D = (-3)^2 - 4*1*5 = 9 - 20 = -11 (-11 < 0 => no real roots)

x1 = (3 - sqrt(-11)) / 2

x2 = (3 + sqrt(-11)) / 2

Answer:

-16

Step-by-step explanation:

        [tex](a*b)^m=a^m * b^m\\[/tex]

        i² = -1

(4i)² = 4² * i²  

        = 16 * (-1)

       = -16

Let's examine what we know:

 [tex](ab)^x=a^x * b^x[/tex]

So, In the equation: [tex](4i)^2[/tex]

  ⇒ is equivalent to ⇒ [tex]4^2*i^2= 16 * (-1) = -16[/tex]

Answer: - 16

Answer:

A. [tex]\frac{7\sqrt{2} }{8}[/tex]

Step-by-step explanation:

Finding the missing side :

7² + x² = 9²

x² + 49 = 81

x² = 32

x = 4√2

Taking the tan value :

tanθ = 7/(4√2)

tanθ = 7(4√2)/4√2(4√2)

tanθ = 28√2/32

tanθ = [tex]\frac{7\sqrt{2} }{8}[/tex]

The 15 years it will take its population to reach 5,000 if  initial population of 20 organisms.

It is defined as the function that rapidly increases and the value of the exponential function is always a positive. It denotes with exponent [tex]\rm y = a^x[/tex]

where a is a constant and a>1

Let's assume the exponential growth is:

[tex]\rm y = Ae^{rt}[/tex]

From the problem:

[tex]\rm 130 = 20e^{5r}[/tex]

[tex]\rm e^{5r}= 6.5[/tex]

Taking ln both side:

We get:

r = 0.374

[tex]\rm 5000 = 20e^{0.374t}[/tex]

After solving, we get:

t = 14.76 ≈ 15 years

Thus, the 15 years it will take its population to reach 5,000 if  initial population of 20 organisms.

Answer:

Step-by-step explanation:

f(x) = 3x² - 3x

g(x) = -5x + 4

Find the value of the function when x = -3:

f(x) = 3x² - 3x

f(-3) = 3(-3)² - 3(-3)

f(-3) = 3(9) + 9

f(-3) = 27 + 9

f(-3) = 36

Find the value of the function when x = 5:

g(x) = -5x + 4

g(5) = -5(5) + 4

g(5) = -25 + 4

g(5) = -21

Answer:

d.  (4w2 + 180w) m2

Step-by-step explanation:

Area of tiled floor = (area of tiled floor+ pool ) - area of pool

area of pool =l x b = 30 x 60 =1800  ...............a

length of pool + tiled floor = 30+2w

breadth of pool + tiled floor = 60+2w

Hence, (area of tiled floor+ pool ) =

(30+2w) x(60+2w) = 1800+60w+120w+4w2 = 1800 + 180w+4w2.....b

b-a =(1800+ 180w+4w2)- 1800 = 4w2 + 180w

Answer:-21

Step-by-step explanation:

The equations which can be used to find the measurement of each angle will be 6x-30=180.

The supplementary angles are defined as the angles whose sum is equal to 180°.

It is given that:-

One angle in a pair of supplementary angles has a value of 2x

The other angle is 30 degrees less than two times the first angle.

Now from the first condition, One angle in a pair of supplementary angles has a value of 2x we can write that:-

2x   +    A   =     180 .........................1

Now from the second condition,The other angle is 30 degrees less than two times the first angle

A     =    4x  -   30 ..............................2

Hence from the above two equations put the value of A in equation 1

the equation will be:-

2x    +   4x    -   30    =    180

6x      -      30        =   180

Hence the equations which can be used to find the measurement of each angle will be 6x-30=180.

The system as per question is

Solve it by elimination, subtract the first equation from the second

Find the value of x

Step-by-step explanation:

well, it changed by 560 miles overall. in a matter of 3 months.

but for the rate of change I have to ask what is the unit of time for that consideration ?

the rate of change is the change of the functional value over an interval divided by the length of the interval.

if 3 months is the unit of time, then the change rate is 560/1 = 560 miles per quarter.

if the unit of time is 1 month, then the change rate is 560/3 miles per month.

if the unit of time is days, then we have 30+31+31 = 92 days in that interval, and the change rate is 560/92 = 140/23 miles per day.

and so on.

A graph is the representation of the data on the vertical and horizontal coordinates so we can see the trend of the data.

Given: The total time for which Noel drives = 152 hours

The total number of successful deliveries = 19

Now, Noel's unit rate for successful delivery is given by:-

[tex]\rm =\dfrac{Total\ succesful\ deliveries}{Total\ hours}=\dfrac{19}{152}=\dfrac{1}{8}[/tex]
