Using linear function concepts, it is found that the speed of the motorboat is of 22 miles per hour.

A linear function is modeled by:

y = mx + b

In which:

In this problem, each second, the position increased by 22, hence the slope is of 22. Since velocity is the distance divided by the time, which in this problem is the slope, the speed of the motorboat is of 22 miles per hour.

Compound interest is the interest levied on the interest. The formula for the calculation of compound interest is given as:-

A = P (1+R/2)^2t

Where, A = Amount after 6 years = $26,000; P = Amount invested now; R = Annual rate of earning = 10% = 0.06; t = time = 6 years.

Substituting;

[tex]26000 = P(1+\dfrac{0.1}{2})^{2*6}=P(1.7958)[/tex]

Therefore, P = 26000/1.7958 = $14478.22

Thus amount will be equal to $14478.22.

Applying the definition of complementary angles, the value of x in the figure given is: 12

Complementary angles are angles that give 90 degrees when added up.

(3x + 6) + 48 = 90 [definition of complementary angles]

Solve for x

3x + 54 = 90

3x = 90 - 54

3x = 36

The given vector Field f(x,y)= [tex]3x^{2} - 5y^{2}[/tex] is not Conservative.

A conservative vector field is a vector field that is the gradient of some function.

The integral is independent of the path that C takes going from its starting point to its ending point.

We know that , the function F conservative if

[tex]\frac{ dP}{dy}[/tex] = [tex]\frac{dQ}{dx}[/tex]

If we prove opposite of this then the function F is not conservative

We have given function , f(x,y)= [tex]3x^{2} - 5y^{2}[/tex]

let P(x,y) = [tex]3x^{2} - 5y^{2}[/tex]  and Q (x,y) =0

Now, [tex]\frac{dP}{dy}[/tex] = -10y

and, [tex]\frac{dQ}{dx}[/tex] = 0

Since [tex]\frac{dP}{dy}[/tex] ≠ [tex]\frac{dQ}{dx}[/tex]

Hence, the field is not conservative.

Answer: I hope this helps!:)

Step-by-step explanation:

The equation of the straight line which has a gradient of -2 and passes through (1, 7) is y = -2x + 9.

The slope-intercept form of the equation

y = mx +c

Here

m is the slope

c is the y-intercept

To find the slope of a line, we find the rate at which the value of 'y' is increasing as we increase the value of 'x' by one unit.

Substituting the point (1, 7) and m = -2 to determine the y-intercept

y = mx +c

7 = (-2)1 + c

c = 7 + 2

c = 9

Thus, the equation of a line using the slope-intercept form is

y = mx +c

m= -2

c = 9

y = -2x + 9

Therefore, we conclude that the equation of a line using the slope-intercept form is y = -2x + 9.

The cost of producing one ball will be $ 0.09261. Then the profit will be if each ball is $ 0.41.

It deals with the size of geometry, region, and density of the different forms both 2D and 3D.

A toy company produces rubber balls that have a radius of 1. 7 cm.

A sphere has a radius of 1. 7 centimeters.

Then the volume of the ball will be

Volume = 4/3 x π x r³

Volume = 4/3 x π x 1.7³

Volume = 20.58 cubic cm

If the price of the rubber needed to produce a ball is $0.0045/cm³.

Then the cost of producing one ball will be

→ 20.58 x 0.0045

→ $ 0.09261

If the company sells a ball for $0.50. Then the profit will be

Profit = 0.50 - 0.09261

Profit = $ 0.41

The best prediction for the number of cells in the colony at 16 hours will be 2300. Then the correct option is B.

Let a be the initial value and x be the power of the exponent function and b be the increasing factor.

The exponent is given as

y = a(b)ˣ

The table is given below.

Time (hours)                Cell population

      0                                 125

      2                                 162

      4                                 258

      6                                 374

      8                                 518

     10                                 763

Then the equations are given as,

125 = a            ...1

763 = ab¹⁰           ...2

From equations 1 and 2, then we have

b¹⁰ = 763/125

b² = 6.104

b = 1.2

Then the equation is given as,

y = 125(1.2)ˣ

Then the best prediction for the number of cells in the colony at 16 hours will be

y = 125(1.2)¹⁶

y = 2311.05

y ≈ 2300

The best prediction for the number of cells in the colony at 16 hours will be 2300. Then the correct option is B.

Answer:

Step-by-step explanation:

First, let's find the area of the box on top. 5*2 is 10. We can see that there is another identical box, so we can multiply the area of one box (10) by 2 to get 20. Now we need to find the middle box. 3*2 is 6. All we have to do now is add all the boxes' areas together. This would be 20+6 (10+10+6), which gives us our answer, 26.
