What is the answer help pls

Answer:

f(x) = 4x - 1

Step-by-step explanation:

The answer to this question is f(x) = 4x - 1 because function notation displays the values of how the input of x yields the output of y. This means that in this form, y is changed to the x input where the substitution of the x in the equation yields the new y.

Answer:

Indian system of numeration:

With the Indian system, when writing a million, a comma comes after the first three digits and then after 2 digits from thenceforth.

For instance, a million would be:

= 10,00,000

Distance to moon in Indian numeration = 3,84,014 km

International System of Numeration:

Here a comma separates a maximum of 3 digits. A million here would be:

= 1,000,000

Distance to moon is therefore:

= 384,014 km

Answer:

18.326 inches

Step-by-step explanation:

The question is basically asking us to find the arc length that the tip of the minute hand travels. The formula for an arc length is S=θr. So we need th find the angle that the minute hand passes through. We know that there is 360 degrees in a cicle and there is 12 stops around a clock, so divide 360 by 12 to find the degrees the minute hand travels every 5 minutes. We ge that every 5 minutes the hand travels 30 degrees, and 35 minutes is 7*5 so we multiple 30*7 to find the angular displacement, and we get 210 degrees. This equation uses radians though so we have to convert, which can be done doing [tex]\frac{210}{1} *\frac{\pi }{180}[/tex], and we ge that θ is [tex]\frac{7\pi }{6}[/tex] so ([tex]\frac{7\pi }{6}[/tex])(5)= 18.326 inches

Answer:

height (h) = 15

Step-by-step explanation:

To figure this out, we use the formula 2 · [tex]\frac{A}{a + b}[/tex], where "A" is the area, "a" is one base measure, and "b" is the other base measure.

After plugging in the numbers into the formula, we get 2 · [tex]\frac{390}{23 + 29}[/tex], which equals 15.

Answer:

Step-by-step explanation:

Step-by-step explanation:

LET THE Point 1 A and point 2 is B

(AB) ^2=(-9-(-3))^2+ (5-(-6))^2+(-4-7)^2=278

AB=16.67 length unit

Midpoint

X=-9-3/2 =-6

Y=5-6/2=-0.5

Z=-4+7/2=-1.5

The distance between points (−3,−6,7) and (−9,5,−4) is 16.6 units, and midpoints are (-6, -0.5, -1.5).

Distance between two points (x₁, y₁, z₁) and (x₂, y₂, z₂) is determined by the following as D² = (x₂-x₁)² + (y₂-y₁)² + (z₂-z₁)²

The midpoint of the line joining  (x₁, y₁, z₁) and (x₂, y₂, z₂)  is given by :

{(x₂+x₁)/2 , (y₂+y₁)/2 , (z₂+z₁)/2}

To determine the distance between points (−3,−6,7) and (−9,5,−4)

Let mid points X, Y, and Z

The given points :  (−3,−6,7) and (−9,5,−4)

Distance between points  (−3,−6,7) and (−9,5,−4) :

D² = (x₂-x₁)² + (y₂-y₁)² + (z₂-z₁)²

D² =(-9-(-3))²+ (5-(-6))²+(-4-7)² = 278

D = √278

D = 16.6 units

The midpoint of the line joining (−3,−6,7) and (−9,5,−4) :

X = (-9-3)/2 = -6

Y =(5-6)/2 = -0.5

Z =(-4+7)/2 = -1.5

Hence, the distance between points (−3,−6,7) and (−9,5,−4) is 16.6 units, and midpoints are (-6, -0.5, -1.5).

Answer:

Hello! The answers will be in explanation :D

Step-by-step explanation:

a) You can use a linear regression calculator online to get the equation. You would get the equation: y = 4.87x + 2.28

b) The slope would be 4.87, m is the slope in the slope-intercept equation. The slope represents that for each puppy that is at birth, their adult weight adds 4.87 pounds each time.

c) The value of the correlation coefficient is 0.989. Again, you could always search up a correlation coefficient calculator online and get the same solution I have.

Hope this helps! ^^

Answer:

Part C. Perform a linear regression and interpret the results.

a. Use a calculator to perform a linear regression. Round the values your calculator gives you for a and b to the nearest hundredth. (2 points)

y = ___4.87____x + ____2.28___

b. What is the slope of the regression equation? What does this mean in terms of birth weight and adult weight? (2 points)

The slope of the regression equation is 4.87. This means that as the puppies get older they will get heavier at a rate of 7.87

c. What is the value of the correlation coefficient? (1 point)

The Correlation coefficient has a value of 0.989

Step-by-step explanation:

Just comparing the given y= +(x-2)^2 + 4 to

                                            y = (x - h)^2 + k

reveals that the vertex is at (h, k):  (2, 4) and that the graph opens up.

The correct graph is the one in the upper left hand area of the illustration.

Step-by-step explanation:

Answer:

To find the perimeter of a polygon, you just have to add the values of each side.

For example, if a rectangle has a length of 10 inches and a width of 5 inches, you would add, 10 + 10 + 5 + 5, which is equal to 30. This is found because the length of one side is 10, the other is also 10, and the width is 5, and the other is also 5.

Answer:

The leading coefficient, a.

Step-by-step explanation:

In a quadratic equation:

y = a*x^2 + b*x + c

The leading coefficient is the coefficient hat that multiplies the variable with the highest power.

In this case, is easy to see that the leading coefficient is a.

We call this the "leading" coefficient because is the coefficient that most impact has on the equation's behavior.

In the case of the quadratic equation, we know that x^2 is always a positive number and is the part that grows faster.

Then if a is a positive number, a*x^2 will be positive, and because this is the part that grows faster, the arms of the parabola will open upwards.

If a is negative, then a*x^2 will be negative, and this will cause that the arms of the parabola open downwards

Then the sign of a defines the direction of the parabola.

And a also defines the width of the parabola.

If a is a really larger number, then

a*x^2 grows really fast

This means that in a small increase of x, we may see a large increase in y, so we will have a "thin" parabola.

On the other hand, if a is really small, a large increase of x will not cause a large increase on y, so we will see a wider parabola.

Then the coefficient a (or variable, depending on which thing are you changing) is the one that controls the parabola's direction and width.
