A digital artist is creating an animation with code. Their code needs to convert polar coordinates to cartesian coordinates, using these formulas:
x = r × cos( θ )y = r × sin( θ )x=r×cos(θ)y=r×sin(θ)
The environment provides these built-in procedures:
NameDescriptionsin(angle)Returns the...
The following code snippet processes a list of strings with a loop and conditionals:
words ← ["belly", "rub", "kitty", "pet", "cat", "water"] counter ← 0 FOR EACH word IN words { IF
(FIND(word, "e") = -1 AND FIND(word, "a") = -1) { counter ← counter + 1 } } DISPLAY(counter)
,The code relies on one string procedure, FIND(source, target), which returns the first index of the string
target inside of the string source, and returns -1 if target is not found.
What value will this program display? correct answer2
Lucie is developing a program to assign pass/fail grades to students in her class, based on their
percentage grades.
Their college follows this grading system:
PercentageGrade70% and abovePASSLower than 70%FAIL
The variable percentGrade represents a student's percentage grade, and her program needs to set grade
to the appropriate value.
Which of these code segments correctly sets the value of grade?
👁️Note that there are 2 answers to this question. correct answerIF (percentGrade ≥ 70) { grade ←
"PASS" } ELSE { grade ← "FAIL" }
The program code is shown below, but it is missing three values: <COUNTER>, <AMOUNT>, and <STEP>.
i ← <COUNTER> REPEAT <AMOUNT> TIMES { DISPLAY(i) DISPLAY(i + 1) i ← i + <STEP> }
Given the displayed output, what must the missing values be? correct answer<COUNTER> = 4,
<AMOUNT> = 2, <STEP> = 1
This program uses a conditional to predict the hair type of a baby.
IF (fatherAllele = "C" AND motherAllele = "C") { hairType ← "curly" } ELSE { IF (fatherAllele = "s" AND
motherAllele = "s") { hairType ← "straight" } ELSE { hairType ← "wavy" } }
In which situations will hairType be "wavy"?
👁️Note that there may be multiple answers to this question. correct answerWhen fatherAllele is "s" and
motherAllele is "C"
When fatherAllele is "C" and motherAllele is "s"
,Darrell is making a program to track his grades. He made the mistake of using the same variable name to
track 3 different test grades, though. Here's a snippet of his code:
a ← 89 a ← 97 a ← 93
What will be the value of a after this code runs? correct answer93
The following procedure calculates the slope of a line and takes 4 numeric parameters: the x coordinate
of the first point, the y coordinate of the first point, the x coordinate of the second point, and the y
coordinate of the second point.
This graph contains a line with unknown slope, going through the points [1, 1][1,1]open bracket, 1,
comma, 1, close bracket and [3, 4][3,4]open bracket, 3, comma, 4, close bracket:
What does the localFavs variable store after that code runs? correct answer"Udupi", "The Flying Falafel",
"Gaumenkitzel", "Rojbas Grill", "Platano", "Cafe Nostos"
Aden is working on a program that can generate domain names.
His program uses the following procedure for string concatenation:
PseudocodeDescriptionconcatenate(string1, string2)Concatenates (joins) two strings to each other,
returning the combined string.
, These variables are at the start of his program:
company ← "cactus" tld1 ← "com" tld2 ← "io"
Which line of code would store the string "cactus.io"? correct answername2 ← concatenate(company,
concatenate(".", tld2))
This program simulates a game where two players try to make basketball shots . Once either player
misses 5 shots, the game is over.
Part 1: How many statements are in the above program?
Part 2: What does the program output? correct answer3

Nanami is researching how much software engineers make. She's writing a program to convert yearly
salaries into hourly rates, based on 52 weeks in a year and 40 hours in a week.
The program starts with this code:
salary ← 105000 wksInYear ← 52 hrsInWeek ← 40
Which lines of code successfully calculate and store the hourly rate?
