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]
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.

"A base of the right solid has an area of 45 ft^2. The height of the right solid it 10 ft. Find the volume of the right solid."
Answers
Answer:
I dont know but example
Step-by-step explanation:
A cubic foot is a cube with a side length of one foot.
We know that, 1 foot = 12 inches.
So, 1 cubic foot is a cube with side length 12 inches.
You can use the formula for the volume of a prism, V=bwh , to convert cubic units.
Since 1 foot = 12 inches, replace b , w , and h with 12 .
V=(12)(12)(12) =1,728
So, 1 cubic foot is equal to 1,728 cubic inches.
Answer: 450^3
Step-by-step explanation: To find the volume of something multiply the base and height. So just do 45x10. And don't forget to put ^3 at the end of your answer because you're finding volume.

Answers
Answer:
4L + 8H = 512 (First answer)
You can take 92 low resolution pictures (second answer)
Step-by-step explanation:
Let L represent the number of low resolution pictures you take and H the number of high resolution pictures you can take.
You only have 512 megabytes.
Therefore, the number of megabytes the low resolution pictures you take plus the amount of megabytes the high rsolution you take in total should be 512
Therefore your equation is:
4L + 8H = 512 (First answer)
You took 18 high resolution pictures, so substitute 18 for H
4L+8(18) = 512
4L+144=512
subtract 144 on both sides
4L=368
divide by 4
L= 92
You can take 92 low resolution pictures

Step-by-step explanation:
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)

What’s the given m ABC = 70 and m ADC = 46
Answers
Answer:
Step-by-step explanation:
Properties of a kite;
1). A kite has one pair of equal angles.
2). A kite has two pairs of adjacent sides.
3). Diagonals of a kite intersect at 90°.
4). Kite has at least one diagonal that bisects the opposite angles.
It's given in the question,
m∠ABC = 70° and m∠ADC = 46°
By the property number -4,
m∠2 = m∠3 = [tex]\frac{70}{2}[/tex] = 35°
m∠8 = m∠9 = [tex]\frac{46}{2}[/tex] = 23°
By the property number - 3,
m∠4 = 90°
By the property of interior angles in a triangle,
m∠3 + m∠4 + m∠5 = 180°
35° + 90° + m∠5 = 180°
125° + m∠5 = 180°
m∠5 = 55°
Similarly, m∠1 + m∠2 + 90° = 180°
m∠1 + 35° + 90° = 180°
m∠1 = 55°
Now m∠6 + 90° + m∠8 = 180°
m∠6 + 90° + 23° = 180°
m∠6 = 180 - 113 = 67°
Therefore, m∠6 = m∠7 = 67°
The values of all 9 angles shown were found using the property of a kite they are:
∠1=55°
∠2=35°
∠3=35°
∠4=90°
∠5=55°
∠6=67°
∠7=67°
∠8=23°
∠9=23°
What are the characteristics of a kite?One pair of equal angles, two pairs of equal adjacent sides, diagonals intersect at a right angle.
∠1=∠6 because AB=AC
∠6=∠7 because AD=DC
∠2=∠3 because triangle ABC is a combination of two congruent triangles.
∠8=∠9 because triangle DAC is a combination of two congruent triangles.
∠4=90°diagonals intersecting at the right angle.
It is given that
∠2+∠3 = 70°
Since they are equal so ∠2=∠3=35
∠8+∠9 = 46°
Since they are equal so ∠8=∠9=23°
∠5 = 180-∠3-∠4 = 180-35-90=55°
Similarly, ∠1 = 55°
∠6+∠7 = 180-∠8-∠9 = 180-46 = 134°
Since they are equal
∠6=∠7 = 67°
Therefore, all 9 angles were calculated using property of a kite.
∠1=55°
∠2=35°
∠3=35°
∠4=90°
∠5=55°
∠6=67°
∠7=67°
∠8=23°
∠9=23°
