Answer:
(x+11)² + (y-3)² = 121
Step-by-step explanation:
Let us assume we are given the following
Centre of a circle: (-11, 3)
Radius: 11
The standard equation of a circle is expressed as;
(x-a)² + (y-b)² = r²
(a, b) is the centre
r is the radius
a = -11, b = 3 and r = 11
Substitute
(x-(-11))² + (y-3)² = 11²
(x+11)² + (y-3)² = 121
Hence the required equation of the circle is (x+11)² + (y-3)² = 121
Note that the centre and the radius of the circle was assumed

Answer:
F
Step-by-step explanation:
F is inversely proportional to d^2.
When F = 5, d = 9
Work out d (positive value rounded to 2 DP) when F = 3
Answer:
11.6
Step-by-step explanation:
F = k/ d^2
where k = proportionality constant
k = Fd^2
k = 5 * 9^2
k = 5*81 = 405
d = (K/F)^1/2
d = (405/3)^1/2
d = 11.62 =11.6
Answer:
11.62
Step-by-step explanation:
F is inversely proportional to d^2, so
[tex]F=\frac{k}{d^2}[/tex]
for some constant k. To find k plug in given values for F and d.
[tex]5=\frac{k}{9^2}\\5=\frac{k}{81}\\k=405[/tex]
Now you can find d for F = 3.
[tex]3=\frac{405}{d^2}\\\\3d^2=405\\\\d^2=135\\d=\sqrt{135}\approx 11.62[/tex]

Item 8: y=x^2-3x-4
Item 9: y=-x^2+3x+4
Answer:
Step-by-step explanation:
similarities:
both items (equations) have the same roots: (-1,0) and (4,0),
both items are in quadratic form
both have a relative min/max at x=1.5
differences:
both have different y-intercepts:
item 8: (0,-4)

what is the angle of a square?
90°
All four inner angles of a square are the same (each being 360°/4 = 90°, a right angle). The central angle of a square is equal to 90° (360°/4). The external angle of a square is equal to 90°.
the total interior angles of a square are 360°.
The sum of exterior angles in a polygon is usually equal to 360 degrees. therefore, for all equiangular polygons, the degree of one outdoors perspective is equal to 360 divided by the number of sides in the polygon.

The relationship between the length and weight of certain sea turtles can be approximated by the equation L = 0,55 W,
where L is the length in feet and W is the weight in pounds. If a sea turtle is 2.5 feet long, which is closest to its weight?
Answer:
4.55 pounds
Step-by-step explanation:
From the above question , we are told that:
The relationship between the length and weight of certain sea turtles can be approximated by the equation
L = 0.55 W,
where
L is the length in feet
W is the weight in pounds. If a sea turtle is 2.5 feet long, which is closest to its weight?
L = 2.5 feet
Hence,
2.5 = 0.55W
W = 2.5/0.55
W = 4.5454545455 pounds
Approximately, weight of the sea turtle in pounds = 4.55 pounds

Answer:
about 7.3 units
Step-by-step explanation:
to find the answer you do Pythagorean theorem
so you have (-9, -4) and (-2, -6)
you do X1-X2 and Y1-Y2
so -4-(6)=2
and -9-(-2)= -7
now you do a^2 + b^2 = C^2
so 2^2 + -7^2 = C^2
which is 4 + 49= C^2
53=C^2
√53=7.3
so 7.3 units :)

Find the value of X and Y write your answer in simplest form does anyone know how to
Answer:
5 = y
7.1 = x
Step-by-step explanation:
(There are so many ways we can solve this, let's solve this the easiest way):
Let's solve for y first =
We can say;
Tan(45) = y/5
Tan(45) * 5 = y
1 * 5 = y
5 = y
Now let's solve for x;
5² + y² = x²
5² + 5² = x²
25 + 25 = x²
50 = x²
[tex]\sqrt{50\\}[/tex] = x
7.1 = x

Y=5 x=50

Okay, I'm gonna name this triangle XYZ.
An isosceles triangle is when two sides are equal. We know that an area of a triangle is always 180 degrees. A right triangle always has one degree of 90 degrees. We know that y∠45, x∠90, so z has to be 45 as well. We know this is a right isosceles triangle due to the angles it has given us.
Now, we know y and z are the same sizes. y=z
using the Pythagorean theorem
take a square root of sums of squares [tex]x=y^2+z^2[/tex]
[tex]5^2=25[/tex]
25+25=50
Rewrite the equation of the line in slope intercept form.
4x−8y=32
Answer:
y=1/2x-4
Step-by-step explanation:
subtract 4x from the left side and the right side. It becomes:
-8y=-4x+32
divide -8 from both sides and it becomes:
y=1/2x-4
Ned types 360 words in 6 minutes. Nate types 220 words in 4 minutes.
Who would type more words in 10 minutes? What assumptions do you
make?
Answer and step-by-step explanation:
We know that Ned types 360 words in 6 minutes while Nate types 220 words in 4 minutes. We are then asked to find out who would type more words in 10 minutes.
To solve this, we need to first reduce the fraction of how many words can be typed to a certain amount of minutes to find how many minutes exactly can Ned and Nate type in one single minute.
Ned types 360 words in 6 minutes, our fraction would be :
[tex]\frac{360}{6}[/tex]
Nate types 220 words in 4 minutes, our fraction would be :
[tex]\frac{220}{4}[/tex]
Now divide both sides by their LCM :
Ned:
[tex]\frac{360/6}{6/6}[/tex]
Nate:
[tex]\frac{220/4}{4/4}[/tex]
Ned :
[tex]\frac{60}{1}[/tex]
Nate:
[tex]\frac{55}{1}[/tex]
This means that in one minute, Ned can type 60 words while Nate can type 55 words. Since we know that 60 is a greater number than 55, we can assume that Ned will type more words than Nate in 10 minutes.

If I am reading the little table right, You have made 9 shots, and have missed 6 of them. Therefore, in total, you have made [tex]9+6=15[/tex] shots.
The definition of probability is the number of events of a desired outcome divided by the total number of outcomes. Since you wish to make a shot for part a, the number of desired outcomes thus far is 9, out of 15 total shots. Thus,
[tex]P([/tex]making a shot[tex])=\frac{9}{15}=\frac{3}{5}=0.6[/tex]
Since making a shot and not making a shot are mutually exclusive events, and the only two events that could occur when shooting a basket, the probability of not making a shot and the probability of making a shot are all of the possible outcomes, and is thus equal to 1.
[tex]P([/tex]making a shot[tex])+P([/tex]missing a shot) [tex]=1[/tex]
[tex]P([/tex]missing a shot[tex])=1-P([/tex]making a shot[tex])[/tex]
[tex]P([/tex]missing a shot[tex])=1-0.6=0.4[/tex]
