// * PLEASE ANSWER * // AB is tangent to circle C. Find AC to two decimal places.
Answer:
19.92
Step-by-step explanation:
To find the length of AC we need to use the Pythagorean theorem: a^2 + b^2 = c^2
a = 6 b = 19
a^2 = 36
b^2 = 361
36 + 361 = 397
c^2 = 397
to find c we take the square root of 397

Answer:
EVERYONE IT IS 3/4 lol
Step-by-step explanation:
The difference of the expression (-3 + 1/2) - (-4 + 1/4) is 3/4.
What is Additive Inverse?Additive inverse in simple terms is meant to add a number with it's opposite sign to get the result as zero.
Mathematically for any number 'a', a + (-a) = 0 implies that -a is the additive inverse of 'a'.
The given expression is, (-3 + 1/2) - (-4 + 1/4).
(-3 + 1/2) - (-4 + 1/4) = [(-3 × 2 + 1) / 2] - [(-4 × 4 + 1) / 4]
= (-7/2) - (-17/4)
The additive inverse of (-7/2) is (+7/2).
Adding and subtracting the additive inverse (+7/2),
(-3 + 1/2) - (-4 + 1/4) = (-7/2) - (-17/4) + (7/2) - (7/2)
= (-7/2) + (17/4) + (7/2) - (7/2)
= [(-7/2) - (7/2)] + [(17/4) + (7/2)]
= (-14/2) + (31/4)
= (-28/4) + (31/4)
= 3/4
Hence the difference of the expression given is 3/4.

Answer:
x = 3
Step-by-step explanation:
Rectangle = length*width = 3(x+12) = 3x+36
Triangle = length*width/2 = 2x*5/2 = 5x
Since the rectangle is 3 times the triangle, thjat gives us:
3x+36 = 3(5x) -> 3x + 36 = 15x
Isolate x and solve:

A living room is 19 feet wide. The carpeted portion of the room is 5x feet long and the adjacent 9) tiled portion of the room is 7y feet long. Use the distributive property to find an expression for the
total area of the living room.
A) 95x + 133y square feet B) 24x + 26y square feet C) 228(x + y) square feet D) 95x + 7y square feet
Answer:
Option A. 95x + 133y square feet.
Step-by-step explanation:
Area of a rectangular room = Length × Width
Length of the room = Length of carpeted portion + Length of the tiled portion
= (5x + 7y) feet
Width of the living room = 19 feet
Area of the living room = (5x + 7y) × 19
= 95x + 133y Square feet [By distributive property]
Therefore, expression for the total area of the living room is option (A).
If the perimeter of a square garden is 84 feet, what is the area of the garden?
А 21 sq ft
B 84 sq ft
С 336 sq ft
D 441 sq ft
Answer:
D.441
Step-by-step explanation:
All sides of a square are equal. Due to this, the perimeter can be expressed as 4 times the side of the square. Let x be the side of a square.
Then we have:
4x = 84
x = 21
The area of a square is written as x^2, as x is both the length and the width.
So your answer will be:
(21)^2 = 441
The area of the garden is 441 sq ft
A square is a quadrilateral with four equal sides.
Characteristics of a square includes:
• The diagonals bisect each other at 90°.
• Opposite sides parallel and of equal length
• The four angles of a square are equal.
Perimeter of a square =4 x length
84 = 4 x length
divide both sides of the equation by 4
84/4 = length
length = 21 feet
Area of a square = length²
21² = 441 sq ft

Write 5 as a ratio of two integers
The number 5 is a rational number, so you must be able to express it as a quotient, and you can. Dividing any number by 1 gives you the original number, so to express an integer like 5 as a quotient, you simply write 5/1. The same is true for negative numbers: -5 = -5/1
-5 = -5/1

lizzy borrowed $900 at 18% interest for christmas gifts. how much will she owe in total after 3 years?
Answer:
$1478.73
Step-by-step explanation:
Use the compound amount factor and assume compounding once per year. Then:
A = $900(1 + 0.18)^3
= $1478.73 due after three years.
Answer:
= $1478.73 or = $1478.72
Step-by-step explanation:
Credit companies charge daily but you only mention yearly question so i will show you yearly and monthly and daily as 3 separate methods.
For years
we use the expression a x {(+1) + b} ^t = 900 x 1.18^3
For months
we use the expressions a x {( +1) +b ^t * 12
We keep to yearly interest
And prove 900 x 1.18^3 = 1478.7288
= $1478.73
Generally, credit companies round down to $1478.72
We work out a yearly rate = 18% interest and divide amount borrowed by 18%
900/18 = 50
then whatever is paid we minus this from the $900 = 900 x 50 = 45,000
50 x 365 = 18,250 owed if no payments were met if agreed to pay monthly but before end of the 3 year contract = meaning if paid at end of month 12- before start of month 13 the 360th day.

2
+v
0
t+h
0
Answer:
5t² - 16t + h =0
Step-by-step explanation:
During upward projection the final velocity is zero, and the gravitational acceleration is -10 m/s² (against the gravity).
Therefore; using the equation;
S = 1/2gt² + ut
Where s is the height h, g is gravitational acceleration, and t is the time and u is the initial velocity u, is 16 ft/s.
Thus; h= 1/2(-10)t² + 16t
We get; h = -5t² + 16t
Therefore; the quadratic equation is 5t² - 16t + h =0

Suppose f(x) is a function such that if p
f(x) can be odd or even.
f(x) can be odd but cannot be even.
f(x) can be even but cannot be odd.
f(x) cannot be odd or even.
Answer:
f(x) can be odd or even.
Step-by-step explanation:
The following information is missing in the question:
Suppose f(x) is a function such that if p < q, f(p) < f(q). Which statement best describes f(x)?
With the information given it is not possible to determine if the function is even or odd.
Even functions: f(-x) = f(x). For examle, (-2)² = 2², then x² is even
Odd functions: f(-x) = -f(x). For examle, (-2)³ = -(2³), then x³ is odd
In both cases, x² and x³, if p < q, f(p) < f(q). For example, 1² < 2², and 1³ < 2³
