Answer:
13: 16
14: 6.28
15: √45
Step-by-step explanation:
13: Count the number of spaces from A to D or B to C, which is 4.
Then, count the number of spaces from A to B or C to D, which is also 4.
After that, multiply the two numbers. You should now have an answer of 16.
14: You want to find the diameter of the circle, which is 2.
Then, multiply 2 by 3.14, aka pi. You should now have an answer of 6.28.
*15: Count the number of spaces from A to C, which is 6.
Then, count the number of spaces from A to B, which is 3.
After that, square both of the numbers. 6 x 6 = 36 and 3 x 3 = 9.
Now, the final step. Add both numbers together. 36 + 9 = 45.
You should now have an answer of √45.
I hope this helped!

The length of a rectangle is 8 feet more than its width. the area of the rectangle is 97 ft.² determine the length and width of the rectangle
Answers
Answer:
L = [tex]\sqrt{113}[/tex] +4
W = [tex]\sqrt{113}[/tex] -4
or L = 14.63 ft, and W = 6.63 ft
Step-by-step explanation:
Let L be the length and W the width.
We are told that the "length of a rectangle is 8 feet more than its width:"
L = W+8
Area of the rectangle is given by L*W, and is 97 [tex]ft^{2}[/tex]
L*W = 97
Substituting L=W+8, we get:
(W+8)W=97 [tex]ft^{2}[/tex]
[tex]W^{2}[/tex] + 8W = 97
[tex]W^{2}[/tex] + 8W - 97 = 0
The roots to this equation are:
-4-[tex]\sqrt{113}[/tex], and[tex]\sqrt{113}[/tex] -4Only the second gives a positive value, so W = [tex]\sqrt{113}[/tex] -4
Since L=W+8, the length, L, is [tex]\sqrt{113}[/tex] -4 + 8 or [tex]\sqrt{113}[/tex] +4
In decimal:
L = 14.63 ft, and W = 6.63 ft

Which functions have a vertex with a x-value of 0? select three options. f(x) = |x| f(x) = |x| 3 f(x) = |x 3| f(x) = |x| − 6 f(x) = |x 3| – 6
Answers
The functions have a vertex with a x-value of 0 will be f(x) = |x|,f(x) = |x|+ 3 and f(x) = |xl - 6.Option 1,2 and 4 are functions have a vertex with a x-value of 0.
What is a function?A connection between independent variables and the dependent variable.is defined by the function. Functions help to represent graphs and equations.
The standard absolute value function is found as;
[tex]\rm f(x) = a|x - h| + k[/tex]
Where,
(h, k) denotes to the vertex
h is the vertex of the x-coordinate
k is the y-coordinate of the vertex
By comparing the standard equation with the given equation in the options we will get the functions to have a vertex with an x-value of 0;
[tex]\rm f(x) = |x| \\\\ \rm f(x) = |x| + 3 \\\\ f(x) = |x| - 6[/tex]
The functions have a vertex with a x-value of 0 will be f(x) = |x|,f(x) = |x|+ 3 and f(x) = |xl - 6.Option 1,2 and 4 are functions have a vertex with a x-value of 0.
Hence options 1,2 and 4 are functions that have a vertex with an x-value of 0.

Answer: d, the diameter, is about 36.92 units
Step-by-step explanation:
The c value is the circumference and we are being asked to solve for the diameter.
We can take the value they give for the circumference, plug it into the circumference formula, and solve for d. Please note that the diameter is two times the radius, or r, so at the end I will multiply r by two.
C = 2πr
(116) = 2πr
18.46 ≈ r
r ≈ 18.46
-
18.46 * 2 = 36.92
The missing measure is about 36.92 units.

Finding m∠HCG
HE is the diameter line [= 180°]∠ECF + ∠FCG + ∠HCG = 180°60° + 75° + ∠HCG = 180°∠HCG = 180° - 135°∠HCG = 45°Finding m∡DF
∠ECF + ∠DCE60° + 45°105°Answer:
m∠HCG = 45°
m∡DF = 105°
Step-by-step explanation:
m∠ECD + m∠ECF + m∠FCG
= 45° + 60° + 75°
= 180°
As angles on a straight line always sum to 180°, we can conclude that the line DG is a straight line and the diameter of the circle, and the Point C is the center of the circle.
Assuming that line EH is also a straight line, using the vertical angles are always congruent theorem, m∠ECD = m∠HCG.
Therefore, m∠HCG = 45°
We always measure arcs in a counterclockwise direction.
⇒ m∡DF = m∡DE + m∡EF
= 45° + 60°
= 105°

Find the area of the figure.
Answers
Step-by-step explanation:
such problems are always the combination of areas of simple figures.
in our case here the simplest way seems to me to calculate the area of the whole 15×15 square (the side lengths are 15 and 9+6 = 15) and then subtract the small 6×6 square (top left), the small 6×3 triangle (bottom right) and the larger 6×9 triangle (top right).
we know that the left side of the main square is 9+6 = 15.
we know that the missing side piece (top right) is also 6 (like its left side). and the right side piece is 15-6-6 = 3.
that is how we know the side lengths of the missing pieces.
so,
15×15 = 225 cm²
the small square is
6×6 = 36 cm²
the large triangle is
6×9/2 = 3×9 = 27 cm²
the small triangle is
6×3/2 = 3×3 = 9 cm²
so, the total area of the figure is
225 - 36 - 27 - 9 = 153 cm²
