Determine the center and radius of the following circle equation: x² + y2 + 2x – 2y – 62 = 0
Answers
Step-by-step explanation:
x²+2x+y²-2y=62
using completing the square
x²+2x+1+y²-2y+1=62+1+1
(x+1)²+(y-1)²=64
(x+1)²+(y-1)²=8²
(x-a)²+(y-b)²=r²
by comparison
(a,b)=(-1,1)
a,b is the center of the circle
r=8unit
r is the radius
Which set of measurements could not represent the side lengths of a right triangle?
A 16 ft, 30 ft, 34 ft
B 9 ft, 12 ft, 15 ft
C 7ft, 24 ft, 25 Ft
D 5ft. 7 ft, 12 ft
Answers
Step by step explanation
16 ft,30 ft 34ft
The set of measurements could not represent the side lengths of a right triangle is 5ft. 7 ft, 12 ft.
What is a right triangle?The right is a triangle with has one angle 90° and square of hypotenuse is equal to the sum of square of other two legs.
Given that, the set of measurements representing the side lengths of a right triangle,
We will check the measurements by seeing if they are following the Pythagoras theorem or not,
Option A)
16 ft, 30 ft, 34
16²+30² = 1156 = 34²
∴ 16²+30² = 34²
Option B)
9²+12² = 225 = 15²
9²+12² = 15²
Option C)
7²+24² = 625 = 25²
7²+24² = 25²
Option D)
5²+7² = 74 ≠ 12²
Since, 5ft. 7 ft, 12 ft set of measurements are not following the Pythagoras theorem.
Therefore, it's not a right triangle.
Hence, The set of measurements could not represent the side lengths of a right triangle is 5ft. 7 ft, 12 ft.

Square FGNM and its diagonals are shown below. Which pairs of line segments are parallel? Select all that apply.
Answers
Answer:
The parallel sides are:
- FG and MN
- GN and FM
Step-by-step explanation:
The question is incomplete, as the image of the square is not attached.
However, I will answer this question using a general rule.
When a square is named ABCD, it means that AB and DC are parallel sides & BC and AD are also parallel
Using this logic, the parallel sides of FGNM are:
- FG and MN
- GN and FM
The diagonals are:
FN and GM

The scale factor of the scale drawing of a mirror to the actual mirror is represented by the ratio 1 : 8 . If the dimensions of the scale drawing are 3 inches wide by 8.5 inches long, what is the actual area of the mirror?
Answers
Answer: 204 square inches
Step-by-step explanation: I’m not really sure, but if you follow through with the normal area identifying method; Length x Width, you should come up with 25.5. After doing this, you could multiply your product by 8 because your actual mirror size is 8 times greater. You will come up with 204 square inches, which would be your final solution. (Once again, I am not sure, just doing how I’ve been understanding from studies).

Answers
Answer: x= 1023 /64
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
64x+1=1024
Step 2: Subtract 1 from both sides.
64x+1−1=1024−1
64x=1023
Step 3: Divide both sides by 64.
64x /64 = 1023 /64
x= 1023 /64
Answer:
1023/64
Step-by-step explanation:
4^3x+1=4^5
64x+1=4^5
64x+1-1=1024-1
64x=1023
64x/64}=1023/64

14. A veterinarian tells Max that his cat
should lose no more than 30 ounces. The
veterinarian suggests that the cat should
0 to
lose 7 ounces or less per week. What is the
shortest time in weeks and days it would
take Max's cat to lose the 30 ounces?
Answers
Answer:
4 weeks 2 days
Answer:
4 weeks 2 days
Step-by-step explanation:
First do 30 divided by 7 to get the number of weeks.
Which is 4 weeks with a remainder of 2.
7 ounces per week is 1 ounce per day.
So to get 2 more ounces that would be 2 days.
Therefore the answer is 4 weeks and 2 days.

-XxDeathshotxX
Answer:
The value of x is 19.
Step-by-step explanation:
The steps are :
3(x- 9) = 30
3(x - 9) ÷ 3 = 30 ÷ 3 [eliminate 3 on left side]
x - 9 = 10
x - 9 + 9 = 10 + 9 [eliminate -9 on left side]
x = 19

Answers
Step-by-step explanation:
ok so for number 1 you first have to group the like terms therefore you will now have:
9r-4r+8-6
and now you calculate:
9r-4r=5r
8-6=2
so that means 5r-2 is simplied version for no.1
for number you 2 you first multiply why is inside the brackets by what is in the outside:
2(x+3y)
2x+6y (simplified version)
