Answer:

Step-by-step explanation:

The vertex form of the quadratic equation is ...

  y = a(x -h)² +k . . . . . . . . . vertex (h, k); vertical scale factor 'a'

Given the vertex, we can find the scale factor by substituting the given point values:

  11 = a(-1 -3)² -5

  11 = 16a -5

  a = (11 +5)/16 = 1

So, the vertex form equation is ...

  y = (x -3)² -5 . . . . . vertex form

Expanding this gives the standard form.

  y = x² -6x +9 -5

  y = x² -6x +4 . . . . . standard form

Step-by-step explanation:

Half of 9.2 is 4.6, so I added the two numbers together because it would be 1.5 inches and the answer is 13.8 miles.

Answer:

3x + y = -16

Step-by-step explanation:

this is because

Step-by-step explanation:

Radius (r) = 7 feet

circumference (c) = ?

We know

C =2 πr

= 2 * 3.14 * 7

= 43.96 feet

Hope it will help :)

Answer:  43.96

==================================================

Work Shown:

C = 2*pi*r

C = 2*pi*7

C = 2*7*pi

C = 14pi ............. exact circumference in terms of pi

C = 14*3.14

C = 43.96

This value is approximate because pi = 3.14 is approximate.

Note: the circumference is the same as the perimeter of the circle. It's the distance around the circle's edge.

7. Definition of midpoint

5. Definition of angle bisector

1reflexive property of equality

According to the Angle Addition Postulate, the total of two angle measurements connected by a common ray equals the size of the angle they produce.

Given,  ∠PSR = ∠PST, and PS bisects the angle ∠ QSU.

Thus From the figure, ∠TSU = ∠QSR

And also given PS bisects the angle ∠ QSU. and p is the same

Thus From the figure  ∠PSU = ∠PSQ

Additive property of length:

The additive property of equality in an equation asserts that the sides stay equal whether we add or subtract the same amount from both sides of the equation. For entire numbers as well, this property is valid.

Definition of angle bisector:

A "Bisector" in geometry is a line that splits a line into two distinct or equal sections. It is applied to angles and line segments.

Definition of an equilateral triangle:

An equilateral triangle in geometry is a triangle with three equal-length sides. An equilateral triangle has congruent sides, which means that each side is the same length. Additionally, each inside angle is identical (60 degrees).

Definition of midpoint:

the location on a line that is equally spaced from both ends. a time interval that lies halfway between the start and finish of an event.

Verticals angle theorem:

According to this theorem, when two straight lines cross, they create two sets of linear pairs with matching angles. The adjacent angles created by the junction of these two lines are likewise said to be supplementary, or equivalent to 180 degrees.

Therefore, Since ∠PSR = ∠PST and PS bisects the angle ∠QSU, ∠TSU = ∠QSR. Since PS divides the angle ∠QSU, ∠PSU = ∠PSQ. It is the same because PS is the same line.

An improper fraction is a fraction where the numerator is greater than the denominator

This is improper because you can't have more parts than the whole. WELL you can, math is confusing

You can have a mixed number, which says how many wholes there are and how many parts of a whole there is.

It's just called an improper fraction just like that I guess,

all you really need to know is that the numerator (the top number) is greater than the denominator (the bottom number), and to make it proper, you have to make it into a mixed number, but you have to use improper fractions to perform some operations.

You'll learn more about converting stuff from improper fractions to mixed numbers and vice versa to perform certain operations in the future, but for now, you just need to know what an improper fraction is.

I hope this helped, let me know if you have any questions.

Answer:

Step-by-step explanation:

An improper fraction is one where the magnitude of the numerator is greater than the magnitude of the denominator.

It is not enough to say that the numerator is greater than the denominator. You need to compare their magnitudes, i.e., their absolute values.

Suppose the fraction is 10/(-23).  10 is greater than -23, but 10/(-23) is not an improper fraction.

Answer:

8.5

Step-by-step explanation:

The required value of the number is 8.5 which is twice the difference between a number and 5 is 7​.

To solve this problem, we first need to express the given information in terms of a mathematical equation.

The statement "Twice the difference of a number and 5 is 7" can be represented as the equation 2 × (x - 5) = 7, where x is the number we're trying to find.

Next, we can solve this equation to find the value of x. To do this, we can first distribute the 2 on the left-hand side of the equation to get 2x - 10 = 7.

Then, we can add 10 to both sides of the equation to get 2x = 17.

Finally, we can divide both sides of the equation by 2 to get x = 17/2 = 8.5.

Therefore, the required value of the number is 8.5.

Answer:

3.28 cm

Step-by-step explanation:

The calculation is given below:

we assume the following things

R denotes the radius of the circle

And, A denotes An arc  

Now , the length of the arc is  

L = (A ÷ 360°) × 2 × 3.14 × R

According to the question

R = 6 cm

Angle = 5 minutes and 15 seconds

The clock could complete its revolution in 60 minutes  

Therefore  

60 minutes = 360°

Also

1 min = 60 seconds

So  

1 seconds =  1min ÷ 60seconds  

Now for 15 seconds it is

= 15 seconds × (1 ÷ 60)

= (15 ÷ 60) min

= 0.25 min

 And for 5 minutes and 15 seconds, it is  

= 5 min + 0.25 min

= 5.25 min

Also

60 minutes = 360°

So,  

1 minute = 360° ÷ 60min

Now For  5.25min

= (5.25min) × (360° ÷ 60min)

= 31.5°

Finally the length would be    

L = (31.5° ÷ 360°) × 2 × 3.14 × 6cm

= 3.28 cm
