2. X 0 4 7 10 13 y -5 -5 -5 -5 -5 Domain: ______________________ Range: _______________________ Function? _______
Answers
Answer:
[tex]Domain =\{0,4,7,10,13\}[/tex]
[tex]Range = \{-5\}[/tex]
[tex]y = -5[/tex] --- function
Step-by-step explanation:
Given
[tex]\begin{array}{cccccc}x & {0} & {4} & {7} & {10} & {13} \ \\ y & {-5} & {-5} & {-5} & {-5} & {-5} \ \end{array}[/tex]
Solving (a): The domain
The x values represent the domain.
Hence, the domain is:
[tex]Domain =\{0,4,7,10,13\}[/tex]
Solving (b): The range
The y values represent the range
Hence, the range is:
[tex]Range = \{-5\}[/tex]
Solving (c): The function
By observation, we can see that for all values of x the value of y remains unchanged (-5)
Hence, the function is:
[tex]y = -5[/tex]

Write the equation of the circle with center (0, 0) and (3, 6) a point on the circle.
Answers
Answer:
Step-by-step explanation:
We will use the standard form of a circle to solve for the radius and then fill it back in. h is 0, k is 0, x is 3, and y is 6:
[tex](3-0)^2+(6-0)^2=r^2[/tex] and
[tex]3^2+6^2=r^2[/tex] and
[tex]9+36=r^2[/tex]
Therefore, r-squared is 45, so the circle's equation in standard form is
[tex](x-0)^2+(y-0)^2=45[/tex] or more simply:
[tex]x^2+y^2=45[/tex]

[tex]-5x+37-37=6x-18-37[/tex]
[tex]-5x=6x-55[/tex]
[tex]-5x-6x=6x-55-6x[/tex]

Answers
Answer:
x = 2
Step-by-step explanation:
0.2x + 0.3 = 0.1x + 0.5 ( subtract 0.1x from both sides )
0.1x + 0.3 = 0.5 ( subtract 0.3 from both sides )
0.1x = 0.2 ( divide both sides by 0.1 )
x = 2
Answer. X will be 2

Which of the following are solutions to the equation below? Check all that apply. 2x2 + 18 x = 20 A. 20 I B. 1 C. -2 O D. -2 E. -10 1 F. -1
Answers
Answer:
B and E
Step-by-step explanation:
To verify which are solutions, substitute the given values into the left side of the equation and if equal to the right side then they are solutions.
A
2(20)² + 18(20) = 800 + 360 = 1160 ≠ 20 ← not a solution
B
2(1)² + 18(1) = 2 + 18 = 20 ← solution
C
2(- 2)² + 18(- 2) = 2(4) - 36 = 8 - 36 = - 28 ≠ 20 ← not a solution
D
Is a repeat of C
E
2(- 10)² + 18(- 10) = 2(100) - 180 = 200 - 180 = 20 ← solution
F
2(- 1)² + 18(- 1) = 2(1) - 18 = 2 - 18 = - 16 ≈ 20 ← not a solution
Then B and E are solutions to the equation
[tex] \huge \mathrm{Answer࿐ }[/tex]
let's solve the quadratic equation :
[tex]2 {x}^{2} + 18x = 20[/tex]
[tex]2 {x}^{2} + 18x - 20 = 0[/tex]
[tex]2 {x}^{2} + 20x -2 x - 20 = 0[/tex]
[tex]2x(x + 10) - 2(x + 10) = 0[/tex]
[tex](2x - 2)(x + 10) = 0[/tex]
So, there are two cases :
Case - 1 (when, 2x - 2 = 0)
[tex]2x - 2 = 0[/tex]
[tex]2x = 2[/tex]
[tex]x = 1[/tex]
Case - 2 (when, x + 10 = 0)
[tex]x + 10 = 0[/tex]
[tex]x = - 10[/tex]
Therefore the required options will be :
B. 1 and E. -10

A rectangle has an area of of 40 square inches, and one of its dimensions is 8, what is the missing dimension?
Answers
Answer:
5
Step-by-step explanation:
To get the area of a rectangle, you just multiply the width * Length. Since you already have one of the dimensions, then just do the oppositie of multiplication by dividing. So you would do 40/8 = 5.
Answer:
5 in
Step-by-step explanation:
The formula for the area of a rectangle of length L and width W is A = L*W.
Here, A = 40 in^2 = (8 in)x, so that
x = (40 in^2) / (8 in) = 5 in

If a,b,c are all non-zero numbers and a+b+c=0, prove that
[tex]a ^{2} / bc + b²/ac + c²/ab = 3[/tex]
no spam and kindly explain your answer!
Answers
Given - a+b+c = 0
To prove that-
a²/bc + b²/ac + c²/ab = 3
Now we know that
when x+y+z = 0,
then x³+y³+z³ = 3xyz
that means
(x³+y³+z³)/xyz = 3 ---- eq 1)
Lets solve for LHS
LHS = a²/bc + b²/ac + c²/ab
we can write it as LHS = a³/abc + b³/abc + c³/abc
by multiplying missing denominators,
now take common abc from denominator and you'll get,
LHS = (a³+b³+c³)/abc --- eq (2)
Comparing one and two we can say that
(a³+b³+c³)/abc = 3
Hence proved,
a²/bc + b²/ac + c²/ab = 3

Answer:
Area of rectangle = 448
Area of semi circle = 402.1
Total area = 850.1
Step-by-step explanation:
Area of rectangle = length times width
Given length = 32 cm
Given width = 14 cm
Area = 32 * 14 = 448
Area of semi circle = πr² / 2
where r = radius
Given diameter = 32cm
To convert diameter to radius simply divide by 2
32 / 2 = 16
So radius 16
now we plug 16 into the formula
[tex]A=\frac{\pi 16^2}{2} \\16^2=256\\256\pi =804.25\\\frac{804.25}{2} =402.12\\A=402.1[/tex](rounded)
Total area = area of semi circle plus area of rectangle
total area = 402.1 + 448 = 850.1
Answer:
Solution given:
length [l]:diameter [d]:32cm
breadth [b]:14cm
radius [r]=32/2=16cm
Area of semi circle:½πr²=½*πx16²=402.12cm²
+
Area of rectangle:l*b=32*14=448cm²
=
Total area =402.12cm²+448cm²= 850.12cm²
