Write the equation of the circle
with center (2,-5) and radius of 4.
*
Answer:
[tex](x - 2) {}^{2} + (y + 5) {}^{2} = 16[/tex]
Step-by-step explanation:
Equation of circle is:
[tex](x - h) {}^{2} + (y - k) {}^{2} = r {}^{2} \\ [/tex]
Here (h,k) are the coordinates of center and r is radius
(h,k) =(2,-5)
r. = 4
plug in the values of h,k and r
[tex](x - 2) {}^{2} + (y - ( - 5)) {}^{2} = 4 {}^{2} \\ (x - 2) {}^{2} + (y + 5) {}^{2} = 16[/tex]
Answer:
[tex](x-2)^2+(y+5)^2=16[/tex]
Step-by-step explanation:
Equation of a circle
[tex](x-a)^2+(y-b)^2=r^2[/tex]
(where (a, b) is the center and r is the radius)
Given:
center = (2, -5)radius = 4Substitute the given values into the equation:
[tex]\implies (x-2)^2+(y-(-5))^2=4^2[/tex]
[tex]\implies (x-2)^2+(y+5)^2=16[/tex]

In the diagram, m ZXYZ = 115° and mZWXY = 45°
Х
Answer:
m∠XWY = 70°
Explanation:
Two opposite interior angle sum up to one exterior angle on a straight line.
============
? + 45° = 115°
? = 115° - 45°
? = 70°
Answer:
The value of angle XWY = 70°
Step-by-step explanation:
=> angle XYZ + angle XYW = 180° { linear pair }
=> angle XYW + 115° = 180°
=> angle XYW = 180° - 115°
=> angle XYW = 65°
Now angle WXY + angle XWY + angle XYW = 180° { sum of angles of a triangle is 180° }
=> 45° + 65° + angle XWY = 180°
=> angle XWY + 110° = 180°
=> angle XWY = 180° - 110°
=> angle XWY = 70°

What is the lateral surface area of this right pyramid with a square base?
Answer:
The lateral surface area of a square pyramid is the sum of the areas of the side faces only, whereas the surface area is the lateral area + area of the base. The lateral area of a square pyramid = 2al (or) 2a√[(a 2 /4) + h 2]. To get the surface area, we need to add the area of the base (which is a 2) to each of these formulas.The surface area of a square pyramid = a 2 + 2al (or) a 2 + 2a[(a 2 /4) + h 2]. where, a = Length of the base (square) l = slant height; h = height of the pyramid.

Answer: You will have to multiply (a+b)×(a+b) . Thus is the formula
Step-by-step explanation: hope it is correct .
Answer:
(a+b)² = a² + 2ab + b²
Step-by-step explanation:
Hello!
This is one of three special binomial products:
(a+b)² = a² + 2ab + b²(a-b)² = a² - 2ab + b²(a+b)(a-b) = a² - b²All you have to do is expand the parenthesis, and this will give you a simple format to follow. This can be used to quickly factor the expanded forms, or quickly multiply the factored forms.

Solve for a side in right triangles
Answer:
The answer is AC = 3.76
Step-by-step explanation:
CohCahToa
Coh: sin(theta) = Opp/Hyp
sin(theta°) = AC/AB
sin(70°) = AC/4
AC = 4*sin(70°)
AC ≈ 3.758770483
AC = 3.76
Answer:
AC = 3.76
Step-by-step explanation:
The opposing side of ∠B needs to be found, where the value of the hypotenuse is given. Take the sin ratio.
sin∠B = AC/4sin70° = AC/40.94 = AC/4AC = 4 x 0.94AC = 3.76the number of gallons of gas were in the tank minus 9 leaves 3 gallons

-What does the “Volume” of a geometric figure mean?
Answer:
The volume relates to the space inside a figure a measurement amount can take-up
Step-by-step explanation:
Order the numbers from least to greatest. 0.3, 9/25, 33%, 0.35
Answer:
0.3(least)
0.33
0.35
0.36(greatest)
Step-by-step explanation:
Okay, so first we need to have all of our numbers in the same category of variable. So first, we will convert 9/25 to a decimal.
To do that, we must divide 9 by 25 to get our answer of 0.36.
Now, we will convert the 33% to a decimal by dividing it by 100 to get 0.33
We now have our list, which should be ordered as:
0.3
0.33
0.35
0.36

Find the missing dimension of the triangle.
Area = 30 mm
-
6 mm
b
b=
mm
Answer:
10 mm
Step-by-step explanation:
We know that the formula for a triangle is A= 1/2(b)(h)
Plug in 30mm for the area as shown and 6 for the base= 30=1/2(6)(h)
Solve= 30=3h
Divide each side by 3 to get h by itself. h=10 or b= 10
depends on which one is missing ^^
A computer is used to generate passwords made up of numbers 0 through 9 and lowercase letters. The computer generates 400 passwords one character at a time.
A uniform probability model is used to predict the first character in the password.
What is the prediction for the number of passwords in which the first character is a vowel?
Round your answer to the nearest whole number.
56 passwords
77 passwords
111 passwords
233 passwords
The prediction for the number of passwords in which the first character is a vowel is 56 passwords.
How to find that a given condition can be modelled by binomial distribution?Binomial distributions consist of n independent Bernoulli trials.
Bernoulli trials are those trials which end up randomly either on success (with probability p) or on failures( with probability 1- p = q (say))
Suppose we have random variable X pertaining to a binomial distribution with parameters n and p, then it is written as
[tex]X \sim B(n,p)[/tex]
The probability that out of n trials, there'd be x successes is given by
[tex]P(X =x) = \: ^nC_xp^x(1-p)^{n-x}[/tex]
The expected value and variance of X are:
[tex]E(X) = np\\[/tex]
Given that the characters that can be used are numbers 0 through 9 and lowercase letters. Therefore, a total of 36 different characters are available.
Since we need to know the passwords made with vowels, therefore, the probability of a password in which the first character will be a, e, i, o, u is (5/36).
Now as the computer produces 400 passwords, therefore, the predicted value can be written as,
[tex]E = np = 400 \times \dfrac{5}{36} = 55.5556 \approx 56[/tex]
Hence, the prediction for the number of passwords in which the first character is a vowel is 56 passwords.

Answer:
1. (10,-4)
2. 12
3. 108
Step-by-step explanation:
First find the cordinate by seing were the point lands on the graph
sense it is +10 right the x = 10, and it is 4 below the origin making it a negitive 4, so u get (10,-4)
The graph is measured 2 units per box and sence the sides are parallel to the axies you can count each square by 2, giving you the measuers of 12 units.
Now finally, The area of a triangle is A=1/2bh, we arlready have our base, and we just found our hight, so now we just have to plug it in.
A= 1/2 (12) (18)
12*18 = 216
A= 1/2 (216)
A= 108
And we are done!
