1. what are the focus and the directrix to a parabola and how do they help you understand about a parabola ?

2. how are the center, radius, and a point on the circle expressed algebraically?

Answers

Answer: 1. What are the focus and directrix of a parabola? Parabolas are commonly known as the graphs of quadratic functions. They can also be viewed as the set of all points whose distance from a certain point (the focus) is equal to their distance from a certain line (the directrix).

2.The center-radius form is: (x−h)2+(y−k)2=r2 Here, the center point is denoted by (h,k) and r is the radius of the circle.

Yesterday, Ian walked 2/3 of a mile. Today, he walked 1/5 of a mile. How far did he walk altogether?

Answers

Answer:

1.4km

Step-by-step explanation:

2/3 + 1/5

Find the LCM of the denominators

(5x2)+(3x1)/15

Clear brackets:

5x2=10

3×1=3

Therefore, we have

10+3/15=13/15

In total, he has walked 13/15 of a mile

1 mile is 1.609344 km

Therfore, he walked 13/15×1.609344 km=1.4km approximately.

2/3 of 1mile is 2/3×1.609344 km

=1.07km

1/5 of 1 mile the next day is 1/5×1.609344 km

=0.32km

Total distance 1.07+0.32=1.39 approximately 1.4km

Ian walked 13/15 miles altogether.

What is fraction?

An element of a whole is a fraction. The number is represented mathematically as a quotient, where the numerator and denominator are split. Both are integers in a simple fraction. A fraction appears in the numerator or denominator of a complex fraction. The numerator of a proper fraction is less than the denominator.

Given:

Yesterday, Ian walked 2/3 of a mile.

Today, he walked 1/5 of a mile.

To find the number of miles, he walks altogether:

The sum of both the fractions,

2/3 + 1/5

= (2 x 5 + 3 x 1) / 15

= (10+3) / 15

= 13/15

Therefore, he walks 13/15 miles.

In a class A of 25 students, 20 passed in first class; in another class B

of 30 students, 24 passed in first class. In which class was a greater

fraction of students getting first class?

Answers

Answer:

class A 20/25 = 4/5

class B 24/30 = 4/5

they are both the same

Answer:

Both classes have the same fraction (80% or 4/5).

Step-by-step explanation:

20 is 4/5 of 25, so 80% of students in Class A passed in first class.

24 is 4/5 of 30, so 80% of students in Class B passed in first class.

Both 20/25 and 24/30 simplify to 4/5, or 80%, so both classes have the same fraction of students passing.

Rick is buying $115 tennis racket from a sporting good store. If the racket is on sale for 35% off in sales tax is 8% how much will he pay in total

Answers

Answer:

$80.73

Step-by-step explanation:

First, find 35% of 115.

35% as a decimal is 0.35 (35/100)

0.35 x 115 = 40.25

Now, subtract 40.25 from 115.

115 - 40.25 = 74.75

Now, to find the sales tax, find 8% of 74.75.

8% as a decimal is 0.08 (8/100)

0.08 x 74.75 = 5.98

Now, subtract add 5.98 to 74.75

5.98 + 74.75 = 80.73

its a sqaure so the angles are 90 degress each.

90 - 38 = 52

answer: C. 52

Answer:

c = 52*

Step-by-step explanation:

If we assume that both shaded triangles are equivalent, and we know that the total angle of a square's corner is 90*, to find the missing angles of the unshaded area (angle z) we just subtract 38 from 90.

90 - 38 = 52*.
