Answer:
2 is the only even prime number.
All the even numbers less than 100 that are prime numbers will be 2.
What is a prime number?A prime number is a positive integer having exactly two factors which are 1 and the number itself. Any number that does not follow this is termed a composite number.
If the number is divisible by 2 then the number will be an even number. Similarly, if the number is not divisible by 2 then the number will be an odd number.
The prime number from 0 to 100 is given below.
2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37, 41, 43, 47, 53, 59, 61, 67, 71, 73, 79, 83, 89, 97

If arc VY = 132° and ∠YUV = 41°, what is the measure of arc XV?
Answer:
50
Step-by-step explanation:
Use this equation
[tex] \frac{b - a}{2} = angle \: yuv[/tex]
where b is arc VY, A is arc XV.
Substitute the equation in
[tex] \frac{132 - a}{2} = 41[/tex]

Which statement describes the line that contains the points (5, -6) and (3, -6)?
A. The line is vertical
B. The line is horizontal
C. The line has a positive slope
D. The line has a negative slope
Answer:
B
Step-by-step explanation:
Using the equation to find the slope, (-6 - -6) / (5 - 3) equals zero. This means that the line has no slope and must be flat.

What is the measure of angle 1?
920
2.
86
88°
90°
92°
Answer:
m∠1 = 88°
m∠2 = 92°
Step-by-step explanation:
From the given figure lines 'k' and 'm' are the parallel lines and line 'L' is the transversal line,
m∠1 + 92° = 180° [Sum of consecutive exterior angles is 180°]
m∠1 = 180 - 92
m∠1 = 88°
m∠1 + m∠2 = 180° [Linear pair of angles are supplementary angles]
88° + m∠2 = 180°
m∠2 = 180 - 88
m∠2 = 92°
which function is equivalent to f(x)=1/4(x-2)^2+3?
f(x)=1/2x+2
f(x)=1/4x^2-4x+7
f(x)=1/4x^2+4
f(x)=1/4x^2-x+4
Answer: f(6) = (6)2 + 1 = 36 + 1 = 37
If we wanted to find and expression for f(g(x)) we could plug in g(x), which is "x - 4" into the function f(x) wherever we see an "x". So:
f(x) = x2 + 1
f(g(x)) = (x - 4)2 + 1 because g(x) is "x - 4"

The total cost for 125 students is $905.5.
What is a word problem?A word problem is a verbal description of a problem situation. It consists of few sentences describing a 'real-life' scenario where a problem needs to be solved by way of a mathematical calculation.
For the given situation,
Grill rental fee = $150
Charge per person for less than 100 students = $5
Charge per person for 100 students or more = $4.25
Total number of students = 125
The total cost for 125 students is
⇒ [tex][150+5(99)]+[150+4.25(26)][/tex]

The vertex form of the equation of a parabola is y = (x + 7)2 + 13. What is the standard form of the equation? O A. y = 7x2 + 14x+ 62 O B. y = x2 + 43x + 32 O c. y = x2 + 7x + 13 O D. y= x2 + 14x + 62
Answer:
y = x^2 + 14x + 62
Step-by-step explanation:
y = (x + 7)^2 + 13 is to be rewritten in the form y = ax^2 + bx + c.
Note: Use " ^ " to denote exponentiation.
Expand y = (x + 7)^2, holding the constant term to be added on later:
y = x^2 + 14x + 49 + 13
Combining the constants, we get:
y = x^2 + 14x + 62 (which matches Answer D).
Based on the problem above, how would you rewrite as a binomial squared?
x^2 + 8x - 3 = 0 (x + __ )^2 = __
Answer:
the quadratic equation cannot be written as the square of a binomial
Step-by-step explanation:
Given the expression
x^2 + 8x - 3 = 0
On factorizing
x = -8±√8²-4(-3)/2
x = -8±√64+12/2
x = -8±√76/2
x = -8±8.7/2
Note that since the since the discriminant is not a prefect square, the quadratic equation cannot be written as the square of a binomial

The first number of a pattern is 400. The pattern follows the rule divide by 2, then add 6. What are the next two terms?
Answer:
206 and 109
Step-by-step explanation:
first term:
400 divided by 2 is 200
200+6= 206
second term:
206 divided by 2 is 103
103+6=109
Answer:
206,109
Step-by-step explanation:
If u divide 400 by 2 it equals 200 then u have to add 6 so its 206.
If u divide 206 by 2 it equals 103 then u have to add 6 and u get 109.

Answer:
x = 36
78°, 36°, 66° (CW from lower left)
Step-by-step explanation:
The sum of angles in a triangle is 180°, so we can write the equation ...
(2x +6)° +x° +(2x -6)° = 180°
5x = 180 . . . . simplify
x = 36 . . . . . . divide by 5
Then the angle measures are ...
(2x +6)° = (2·36 +6)° = 78°
x° = 36°
(2x -6)° = (2·36 -6)° = 66°
Answer:
Top angle - 36
Left angle - 78
Right angle - 66
Step-by-step explanation:
First to find the angles you need to find x. Do this by adding all the angle measurements and setting them equal to 180 because all triangles equal 180.
x+2x+6+2x-6=180Then, combine like terms
5x=180Finally, divide both sides by 5
x=36Now that you know x you can plug it in to find the rest of the angles. The top angle is simply 36. The left angle is 2(36) + 6, which equals 78. The right angle is 2(36) - 6, which equals 66.

Given cot A= 11/60 and that angle A is in Quadrant I, find the exact value of cos cos A in simplest radical form using a rational denominator.
Answer: Below
Step-by-step explanation:cotA=11/60
tan=opposite/adjacent
cot=1/tan
cot=adjacent/opposite
cotA=11/60
adjacent=11
opposite=60
using the Pythagorean Theorem, the hypotenuse=61
csc=1/sin
cscA=1/sinA
sin=opposite/hypotenuse
sinA=60/61
csc=1/sin
cscA=61/60
The value of Cos A is [tex]\frac{11}{61}[/tex].
What is cosine of an angle?The cosine of an angle is defined as the sine of the complementary angle. The complementary angle equals the given angle subtracted from a right angle, 90°. For instance, if the angle is 30°, then its complement is 60°.
According to the given problem,
Given, cot A = [tex]\frac{11}{60}[/tex], and angle A is in first quadrant then, all the function's value will be positive in nature.
Now, cot A = [tex]\frac{Base}{Perpendicular}[/tex]
cot A = [tex]\frac{11}{60}[/tex]
Base = 11
Perpendicular = 60
Using the Pythagorean Theorem
Hypotenuse² = Perpendicular² +Base²
⇒ Hypotenuse² = 11² + 60²
⇒ hypotenuse = 61
Then, Cos A = [tex]\frac{Base}{Hypotenuse}[/tex]
Cos A = [tex]\frac{11}{61}[/tex]
Hence, we can conclude that Cos A is [tex]\frac{11}{61}[/tex].
