A student asks how you can find the quotient and the remainder in a division problem like

593

÷

36

using a calculator that can perform only the four basic operations. How do you respond?

Answers

Answer:

16.4722222222

Step-by-step explanation:

The quotient and remainder should be 16 and 17 respectively.

Given that,

The problem is 593 ÷ 36.By using the calculator we can perform the four operations i.e. addition, subtraction, multiplication & division.

The division result in the division operator is

593 ÷ 36  = 16.4722So, the quotient is 16.

Now the remainder should be

(16.4722 - 16) ×36 = 17

Therefore we can conclude that the quotient and remainder should be 16 and 17 respectively.

Answer: -15

Step-by-step explanation:

The average rate of change for the interval from x = 7 to x = 8 is -15. The correct option is B.

What is quadratic function?

A quadratic polynomial in mathematics is a polynomial of degree two in one or more variables. The polynomial function defined by a quadratic polynomial is known as a quadratic function.

Since the quadratic function has a vertex at (0,3), the equation for the function can be written in vertex form as:

y = a(x - 0)^2 + 3

Where "a" is a constant that determines the shape of the parabola. To find the value of "a", we can use one of the other points on the parabola. Let's use the point (1, 2):

2 = a(1 - 0)^2 + 3

Simplifying this equation, we get:

a = -1

So the equation for the quadratic function is:

y = -x^2 + 3

Now we can use this equation to find the average rate of change between x = 7 and x = 8. The value of the function at x = 7 is:

y = -7^2 + 3 = -46

The value of the function at x = 8 is:

y = -8^2 + 3 = -61

The average rate of change between x = 7 and x = 8 is:

(y2 - y1) / (x2 - x1) = (-61 - (-46)) / (8 - 7) = -15

Therefore, the average rate of change for the interval from x = 7 to x = 8 is -15.

The residual for a predicted relative abundance when the rainfall was 3 inches is 1.25. What is the actual relative abundance when the rainfall was 3 inches

Answers

Answer:

The actual relative abundance will be "7.59".

Step-by-step explanation:

The residual on something like a curve anywhere at a point becomes expressed as the maximum at either the position between some of the real y-value as well as the expected y-value. Consequently, the difference regarding true relative abundance as well as expected relative abundance seems to be 1.25 whether we presume that the x-variable represents rainfall, as well as they-variable, represents the relative abundance of locusts.

The predicted relative abundance for 3 inches rainfall will be:

= [tex]6.7 - (0.12\times 3)[/tex]

= [tex]6.34[/tex]

The residual will be:

= [tex]actual - predicted \ relative \ abundance[/tex]

= [tex]1.25[/tex]

Now,

The actual relative abundance will be:

= [tex]1.25 + predicted \ relative \ abundance[/tex]

= [tex]1.25 + 6.34[/tex]

= [tex]7.59[/tex]

Remember that perhaps the residual positive value means that even the calculation underestimates the relative abundance. The real relative abundance, however, is 7.59.

Answers

Answer:

x = 31.8

Step-by-step explanation:

From the picture attached,

By applying Pythagoras theorem in right ΔADC,

AC² = AD² + CD²

(22)² = AD² + (16)²

AD² = 484 - 256

AD = √228

     = 2√57

Now we apply Pythagoras theorem in right ΔADB,

AB² = AD² + DB²

x² = 228 + (44 - 16)²

x² = 228 + 784

x² = 1012

x = √1012

  = 31.81

  ≈ 31.8

The side x is an hypotenuse side to one of the right triangles formed by

altitude of the given triangle that has solid lines.

x is approximately 31.812

Reasons:

The figure shows a triangle with an altitude that forms two triangles inside

the main triangle.

By Pythagoras's theorem, we have;

For the right triangle on the left;

22² = h² + 16²

h² = 22² - 16² = 228

h² = 228

h = √228 = 2·√57

h = 2·√57

In the right triangle to the right, we have;

The length of the top base, b = 44 - 16 = 28

The square of the hypotenuse, x² = h² + b²

∴ x² = 228 + 28² = 1012

x = √(1012) = 2·√253

x = 2·√253 ≈ 31.812
