A rectangular sign has length of 3 and 1/2 ft and a width of 1 and 1/8 ft. Will the area of the sign be greater or less than 3 and 1/2 square ft? How do you know? What is the area of the sign?
Answers
Answer:
[tex]Area = 3\dfrac{15}{16}\ sq\ ft[/tex]
Area is greater than [tex]3\frac{1}{2}[/tex] sq ft.
Step-by-step explanation:
Length of rectangular sign board = [tex]3\frac{1}{2}[/tex] ft
Width of rectangular sign board = [tex]1\frac{1}{8}[/tex] ft
Area of a rectangle is given by the formula:
[tex]A = Length \times Width[/tex]
To find the area, we are going to multiply [tex]3\frac{1}{2}[/tex] with [tex]1\frac{1}{8}[/tex].
[tex]1\frac{1}{8}[/tex] is greater than 1.
Therefore the multiplication will be greater than [tex]3\frac{1}{2}[/tex].
Hence, we can say that area will be greater than [tex]3\frac{1}{2}[/tex] sq ft.
Area of the sign:
[tex]A = 3\dfrac{1}{2}\times 1\dfrac{1}8\\\Rightarrow A = \dfrac{7}{2}\times \frac{9}8\\\Rightarrow A = \dfrac{63}{16}\\\Rightarrow A = 3\dfrac{15}{16}\ sq\ ft[/tex]

A small swimming pool initially contains 400 gallons of water, and water is being added at a rate of 10 gallons per minute. Which expression represents the volume of the pool after minutes?
-10t + 400
10t + 400
400t + 10
400(1.1)^t
Answers
Answer:
10t + 400 would be the answer.
Step-by-step explanation:
every hour, there would be 10 gallons added to the pool, so time should be the letter "t" in the equation.
Also, there's already 400 gallons of water existing in the pool, so we need to add 400 gallons.
Therefore, 10t + 400 would be the answer.

Function s is the set of points: {(4,3),(5,3),(8,6),(9,6),(12,9),(13,9)}
(a) What is the inverse of function s?(b) the inverse of function s a function?
Explain your answer.
Answers
Given:
The function in the form of set of points is
[tex]s:\{(4,3),(5,3),(8,6),(9,6),(12,9),(13,9)\}[/tex]
To find:
(a) The inverse of function s.
(b) whether the inverse of function s is a function?
Solution:
(a)
If a function is [tex]f:\{(a,b),a,b\in R\}[/tex], then its inverse function is
[tex]f^{-1}:\{(b,a),a,b\in R\}[/tex]
We have,
[tex]s:\{(4,3),(5,3),(8,6),(9,6),(12,9),(13,9)\}[/tex]
So, inverse of this function is
[tex]s^{-1}:\{(3,4),(3,5),(6,8),(6,9),(9,12),(9,13)\}[/tex]
Therefore, the inverse of function s is [tex]s^{-1}:\{(3,4),(3,5),(6,8),(6,9),(9,12),(9,13)\}[/tex].
(b)
A set of point is a function if there exist unique output for each input.
In inverse of s, we have two output values y=4 and y=5 for single input x=3.
Therefore, the inverse of function s is not a function.
∠ and ∠ are supplementary angles. If ∠ = (2 − 30)° and ∠ = 4, find the measure of the larger angle
Answers
Answer:
We get ∠A =40° and ∠B = 140° and ∠B = 140° is measure of larger angle
Step-by-step explanation:
we have ∠A = (2x − 30)° and ∠B = 4x, and we need to find measure of larger angle. And ∠A and ∠A are supplementary angles.
If the angles are supplementary there sum is equal to 180° i.e ∠A + ∠B = 180°
So, First we have to find the value of x. and then we can determine larger angle.
We know: ∠A + ∠B = 180
2x-30+4x=180
6x-30=180
6x=180+30
6x=210
x=210/6
x=35
So, value of x is x=35
Now finding ∠A and ∠B
∠A = (2x − 30)°
∠A = (2(35) − 30)°
∠A = (70 − 30)°
∠A =40°
and ∠B = 4x
∠B = 4(35)
∠B = 140°
So, we get ∠A =40° and ∠B = 140° and ∠B = 140° is measure of larger angle

Vertex form of the quadratic function
If the graph of the quadratic function has a vertex at the point (h,k), then the function can be written as:
[tex]y=a(x-h)^2+k[/tex]
Where a is the leading coefficient.
We are given the following function:
[tex]y =-2x^2-4x+7[/tex]
To find the vertex, we need to complete squares. First, factor -2 on the first two terms:
[tex]y =-2(x^2+2x)+7[/tex]
The expression in parentheses must be completed to represent the square of a binomial. Adding 1 and subtracting 1:
[tex]y =-2(x^2+2x+1- 1)+7[/tex]
Taking out the -1:
[tex]y =-2(x^2+2x+1)+2+7[/tex]
Factoring the trinomial and operating:
[tex]y =-2(x+1)^2+9[/tex]
Comparing with the vertex form we have
Vertex (-1,9)
Leading coefficient: -2
Since the leading coefficient is negative, the function has a maximum value at its vertex, i.e.
Maximum: (-1,9)

The missing step for solution of the expression is,
⇒ Divide both sides of the equation by 10.4.
What is an expression?Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
Now, We have been given an expression:
2.3 + 8(1.3x - 4.75) = 629.9
Hence, We will solve the above equation for x as;
First distribute the parenthesis over 8 we get:
2.3 + 10.4x - 38 = 629.9
Now, subtract 2.3 on right hand side of the above equation we get:
10.4x - 38 = 629.9 - 2.3
10.4 x = 627.6 + 38
10.4 x = 665.6
Hence, the last step would be divide by 10.4 to get the value of x
x = 64
Therefore, option 4th is correct.
