Which equation has the following: Center (0, -3) and radius: square root of 11.
A. x2 + (y - 3)2 = 11
B. x2 + (y - 3)2 = 121
C. x2 + (y + 3)2 = 11
D. x2 + (y + 3)2 = 121
Answer:
[tex]\text{C. }x^2+(y+3)^2=11[/tex]
Step-by-step explanation:
The equation of a circle with radius [tex]r[/tex] and center [tex](h, k)[/tex] is given by:
[tex](x-h)^2+(y-k)^2=r^2[/tex].
What we're given:
radius of [tex]\sqrt{11}[/tex] center at [tex](0,-3)[/tex]Substituting given values, we get:
[tex](x-0)^2+(y-(-3))^2=\sqrt{11}^2,\\\boxed{\text{C. }x^2+(y+3)^2=11}[/tex]

The sum of a number and two is equal to negative seven. Translate this sentence to an equation and then find the number.
Answer: -9
Step-by-step explanation:
Given
The sum of a number and two is equal to negative 7
Suppose x is that number
[tex]\therefore x+2=-7\\\text{add -2 both sides}\\\Rightarrow x+2-2=-7-2\\\Rightarrow x=-9[/tex]
So, the number is [tex]-9[/tex].
The area of a square can be found using the equation A = s, where A is the area and s is the measure of one side of the square.
Match the equation for how to solve for the side length of a square to its description.
A square has an area of 227 in^2?
Answer:
s = √227 in
Step-by-step explanation:
A = s²
Where,
A = Area of a square
s = side length of the square
Find the side length of a square with area of 227 in²
A = s²
227 in² = s²
Find the square root of both sides
√227 in² = √s²
√227 in² = s
s = √227 in
Answer:
s = √227 in

Height of the Qutab Minaar is 73 metre. When the last stone on the top of the Qutab Minaar was carried from ground to its top by labour weighting 50 kg (bricks carried weighted 20kg), how much work was done in that job by gravitational force? (g = 10 m/s2)
(d) –12770J
(a) –32110 J
(b) –51100 J
(c) –76990J
Answer:
peanut butter jelly sandwich
The work done by gravitational force is -51100 J
What is gravitational force?Gravitational force is the force of attraction between all masses in the universe. It is the weakest of all the natural forces. It depends on the mass and distance of the objects.
Given that, a labour has weight 50 kg and bricks carried weighted 20kg to the top of the tower of height 73 m, we need to find the work done by the gravitational force,
W = height × weight × gravity
W = 73 × (50+20) × 10
W = 73 × 70 × 10
W = 51100 J
Hence, the work done by gravitational force is -51100 J

A 10 ft by 10 ft square garden contains a large walking path through the diagonal what is the area of the walking path shown in the grey above
Answer:
64 ft^2
Step-by-step explanation:
Area of shaded part = area of a square = 2 x area of a triangle
area of a square = length^2
10^2 = 100 ft^2
Area of a triangle = (1/2) x base x height
1/2 x 6 x 6 = 18 ft^2
area of shaded part = 100 - 2x 18 = 64 ft^2
A bag contains 6 white marblesw and 4 black marbles.a marble is drawn from the bag and then a second marble is drawn without replacing the first one. what is the probability of drawing a white marble on the first draw and another white marble on the second draw
Answer:
60.5%
Step-by-step explanation:
60% white, 40% black
The first draw you have a 60% chance drawing a white marble, the second time you have a 55% chance since you already drew one in the first round. so i think it is 60.5%% chance drawing white on both rounds since I add 60+55=121. 121/200=60.5%

Line segment TU has endpoints (-7,10) and (-6,-5). What is the length of TU to the NEAREST TENTH?
Answer: 15 units
Step-by-step explanation:
Given
The endpoints of the line segment are [tex](-7,10)\ \text{and}\ (-6,-5)[/tex]
The length of the line segment is given by the distance formula i.e.
[tex]d=\sqrt{\left( x_2-x_1\right)^2+\left( y_2-y_1\right)^2}[/tex]
Insert the values,
[tex]\Rightarrow d=\sqrt{\left( -6+7\right)^2+\left( -5-10\right)^2}\\\Rightarrow d=\sqrt{1^2+\left( -15\right)^2}\\\Rightarrow d=\sqrt{1+225}\\\Rightarrow d=15.0\ \text{units}[/tex]
Therefore, the length of line segment TU is 15 units

Every day, Bridgette's burrito stand uses 7/10 of a bag of tortillas. How many days will 6 3/10 bags of tortillas last?
Answer:
Number of days bags of tortillas will last = 9 days
Step-by-step explanation:
Total bags of tortillas =6 3/10
Bag of tortillas used per day = 7/10
How many days will 6 3/10 bags of tortillas last?
Number of days bags of tortillas will last = Total bags of tortillas / Bag of tortillas used per day
= 6 3/10 ÷ 7/10
= 63/10 × 10/7
= 63*10 / 10*7
= 630/70
= 9
Number of days bags of tortillas will last = 9 days

The ages of trees in a forest are normally distributed with a mean of 25 years and a standard deviation of 5 years.
Complete question is in comment section :
Answer:
68%
Step-by-step explanation:
Mean = 25
Standard deviation = 5
The percentage of trees between 20 and 30
20 trees = 1 standard deviation below the mean ; mean - 1(standard deviation)
25 - 5 = 20
30 trees = 1 standard deviation above the mean ;
Mean + 1(standard deviation) ;
25 + 5 = 30
This means, 20 and 30 lies ±1 standard deviation from the mean which according to the empirical rule is 68%
According to the empirical rule :
POSSIBLE POINTS: 20
