Myra wrote a computer program that had 75 lines of code. She realized that she could make the code more efficient and removed 20% of the lines.
Shade the grid to show the percent that Myra removed.
Answer:
Now Myra has 60 lines of code, no grid picture attached.
Step-by-step explanation:
If Myra removed 20% of the lines and she started with 75 lines of code, then she is removing 1/5 of those lines of code.
75 divided by 5 is 15, and 75 - 15 = 60
Now Myra would have 60 lines of code. It's unclear what grid you are talking about though - could you attach a picture of the grid you need to shade in?

The orbital period, P, of a planet and the planet’s distance from the sun, a, in astronomical units is related by the formula P = a Superscript three-halves. If Saturn’s orbital period is 29.5 years, what is its distance from the sun?
Answer:
9.54731702 astronomical units
Step-by-step explanation:
[tex]P=a^{\frac{3}{2} }[/tex]
Substitute this value in the equation above:
[tex]29.5=a^{\frac{3}{2} }[/tex]
⇒ [tex](29.5)^{\frac{3}{2} } =a[/tex]
⇒ [tex]a=9.54731702[/tex] [tex]astronomical[/tex] [tex]units[/tex]

What is the value of x in the below diagram?
(2 x + 2)
(x + 34)°
Answer:
Step-by-step explanation:
x+34+2x+2=180 degree (being liear pair)
3x+36=180
3x=180-36
x=144/3
x=48
Answer:
x + 34° + 2x + 2° = 180°
3x = 180° - 34° - 2°
3x = 144°|: 3
x = 48°
x + 34° = 82° and 2x + 2° = 50°

Answer:
[tex]\lim_{x \to 3} g(x) = DNE[/tex]
Step-by-step explanation:
Observations:
As x approaches 3 from the left side, f(x) approaches -1.6 As x approaches 3 from the right side, f(x) approaches 1.6Conclusion:
Because the right and left-side limits are not equal to each other, the limit does not existTherefore, [tex]\lim_{x \to 3} g(x) = DNE[/tex]Answer:

If f(1) =4 and f(n) = -4f(n-1) + n then find the value of f(5)
======================================================
Work Shown:
We use the first term to build to the second term.
Plug in n = 2
f(n) = -4f(n-1) + n
f(2) = -4f(2-1) + 2 ..... n replaced with 2
f(2) = -4f(1) + 2
f(2) = -4*4 + 2 ......... f(1) replaced with 4; since f(1) = 4
f(2) = -16 + 2
f(2) = -14
The second term is -14
------------------
Repeat for n = 3
f(n) = -4f(n-1) + n
f(3) = -4f(3-1) + 3 ..... n replaced with 3
f(3) = -4f(2) + 3
f(3) = -4*(-14) + 3 ......... f(2) replaced with -14
f(3) = 56 + 3
f(3) = 59
The third term is 59
------------------
We keep going until we get to f(5)
Plug in n = 4
f(n) = -4f(n-1) + n
f(4) = -4f(4-1) + 4 ..... n replaced with 4
f(4) = -4f(3) + 4
f(4) = -4*(59) + 4 ......... f(3) replaced with 59
f(4) = -236 + 4
f(4) = -232
The fourth term is -232
------------------
Just one more section
Plug in n = 5
f(n) = -4f(n-1) + n
f(5) = -4f(5-1) + 5 ..... n replaced with 4
f(5) = -4f(4) + 5
f(5) = -4*(-232) + 5 ......... f(4) replaced with -232
f(5) = 928 + 5
f(5) = 933
The fifth term is 933
------------------
As you can see, recursive sequences can get tedious for fairly large values of n. We need to compute every term before f(5) to figure it out. So if your teacher needed you to compute something like f(10), then it would get even worse. Sometimes it's possible to find a closed formula for it, but it may be tricky to find.

The theater sells two types of tickets adult tickets for 6 and child tickets for 5 Last Night,the theater sold a total of 259 tickets for a total of 1397.How many adult tickets did the theater sell last night
Answer: 102
Step-by-step explanation:
Let the number of adults tickets be represented by x
Let the number of children tickets be represented by y.
We can then form an equation which will be:
x + y = 259 ....... i
6x + 5y = 1397 ...... ii
From equation i, y = 259 - x ...... iii
Put equation iii into ii
6x + 5y = 1397
6x + 5(259 - x) = 1397
6x + 1295 - 5x = 1397
Collect like terms
6x - 5x = 1397 - 1295
x = 102
The number of adult tickets that the theater sold last night is 102.

Which angle is complementary to ∠X?
Answer:
Complementary angles sum to 90°.
∠X has ∠P complementary to it as:
P + X = 90°Three rays have a common vertex on a line. Write and solve equations to find the measures of m and n
Answer:
n = 90 - 62
n = 28º
m = 180 - (62 + n + 27)
m = 180 - (62 + 28 + 27)
m = 180 - 117
m = 63º

The exponential function is f(x) = 2(3)^x, the correct option is A.
What is a function?
Function is a type of relation, or rule, that maps one input to specific single output.
In mathematics, a function is an expression, rule, or law that describes the relationship between one variable (the independent variable) and another variable (the dependent variable) (the dependent variable). In mathematics and the physical sciences, functions are indispensable for formulating physical relationships.
Linear function is a function whose graph is a straight line
We are given that;
The graphs of the function
Now,
we can identify which exponential function is represented by the graph:
The graph crosses the y-axis at (0, 2), so the y-intercept is 2. This means that a = 2.
The graph is increasing as x increases, so b > 1. We can find b by using another point on the graph, such as (1, 6). We can substitute these values into the formula and solve for b:
f(1) = 2b^1
6 = 2b
b = 3
Therefore, the exponential function will be f(x) = 2(3)^x.

BDC = BAC
BAC = 29°
BOC = 2BDC
= 2×29
= 58°
Answer:
m<BAC = 29 degrees
m<BOC = 58 degrees
Step-by-step explanation:
<BAC, <BDC, and <BOC share the same arc.
<BAC and <BDC are inscribed angles, and will have the same angle measure, 29 degrees.
<BAC and <BDC are inscribed angles, so their measure is 1/2 of the measure of the arc.
The measure of arc BC is 58 degrees.
<BOC is a central angle. The angle measure of a central angle is equal to the measure of the arc.
The measure of <BOC is 58 degrees.

rhombus wxyz with vertices w(1 0) x(4,-1) y(5,-4) and z(2,-3)
Answer:
W 2,3
X 5,3
Y 1,2
Z 8,4
Step-by-step explanation:
The coordinates of the Rhombus after the dilation is W' ( 3 , 0 ) , X' ( 12 , -3 ) , Y' ( 15 , -12 ) and Z' ( 6 , -9 )
What is Dilation?Resizing an item uses a transition called Dilation. Dilation is used to enlarge or contract the items. The result of this transformation is an image with the same shape as the original. However, there is a variation in the shape's size. Dilation transformations ensure that the shape will stay the same and that corresponding angles will be congruent
The result of dilation is that the shapes and boundaries of objects in the input image are expanded or thickened. It is often used in conjunction with other morphological operations such as erosion, opening, and closing to manipulate and enhance images.
Given data ,
Let the coordinates of the rhombus be represented as WXYZ
where W' ( 1 , 0 ) , X ( 4 , -1 ) , Y ( 5 , -4 ) and Z ( 2 , -3 )
Now , the dilation scale factor is k = 3 centered at origin
So , result of this transformation is an image with the same shape as the original
The coordinates of the dilated figure is W'X'Y'Z'
where W' ( 3 , 0 ) , X' ( 12 , -3 ) , Y' ( 15 , -12 ) and Z' ( 6 , -9 )
Hence , the dilation is solved
