2(x+3)^2+2(y)^2=32 what is the center point of the circle and how long is the radius

Mathematics

spayn [35]3 years ago

Answer:

  • center (-3, 0)
  • radius 4

Step-by-step explanation:

The standard form equation of a circle is ...

  (x -h)^2 +(y -k)^2 = r^2 . . . . . . . . . center at (h, k), radius r

Divide your given equation by 2 to put it into standard form:

  (x +3)^2 +y^2 = 16

Comparing to the above, we see ...

  • h = -3
  • k = 0
  • r = √16 = 4

The center point of the circle is (-3, 0); the radius is 4 units long.

Can someone help me with this proof
maksim [4K]

Step-by-step explanation:

Given :

Given that lines a and b are parallel, angles 1 and 5 are congruent because they are corresponding angles, and angles 1 and 4 are congruent because they are vertical angles

To find : by which property are angles 4 and 5 congruent

Solution :

We know that if two parallel lines are cut by a transversal, then the pairs of alternate interior angles are congruent.

Also, we know that if two things are equal to the same thing then they are equal to each other . In this case, we can say that if two angles are congruent to a third angle, then they are congruent to each other. As angles 4 and 5 are both congruent to angle 1, they are congruent to each other but angles 4 and 5 are alternate interior angles. So, if parallel lines have a transversal, alternate interior angles are congruent.

The data in the table represents the average number of daylight hours each month in Springfield in 2015, rounded to the nearest
Lera25 [3.4K]
To do part B, use the equation that you wrote for part A.  We need to figure out what month number March of 2020 will be; we started in January 2015 at month 1; month 2 was Feb. 2015; month 3 was Mar. 2015; etc. to month 12 at Dec. 2015.  Then month 13 will be Jan. 2016; month 13+12=25 will be Jan. 2017; month 25+12=37 will be Jan. 2018; month 37+12=49 will be Jan. 2019; month 49+12=61 will be Jan. 2020; month 62 will be Feb. 2020; and month 63 will be March 2020.  

63 is the number you will substitute for x in the equation you've already written for part A.

Marla did 64 sit-ups each day for one week. Use the distributive property to sow an expression you ca. Use to find the total num
ELEN [110]

Answer:

Marla did 64 sit ups each day for one week = (60*7)+(4*7)= 448

Marla did 64 sit ups each day for one week =(50*7)+(14*7)= 448

Marla did 64 sit ups each day for one week =(40*7)+(24*7)= 448

Step-by-step explanation:

Marla did 64 sit ups each day for one week = 64 *7 = 448

A distributive property allows us to multiply a sum by multiplying each addend separately first and then summing the products together.

64 sit ups could be written as 60+4, 50+14 or 40+24.

Apply the distributive property:

Marla did 64 sit ups each day for one week = (60*7)+(4*7)= 448

Marla did 64 sit ups each day for one week =(50*7)+(14*7)= 448

Marla did 64 sit ups each day for one week =(40*7)+(24*7)= 448

We can try any two numbers whose sum is 64 and all will give us the answer 448....
