Question #5
Charles cut a slice from a circular pizza with the diameter shown below.
Pizza
15 inches
The slice has an arc length of 21.5 inches along the crust. What is the approximate measure of the
central angle of the slice of pizza Charles cut?
A) 82
B) 164
C) 196
D) 278°
Answer:
Step-by-step explanation:
The approximate measurements of the central angle of the slice of pizza Charles cut will be 164 degrees. The correct option is B.
What is the Length of an Arc?The arc length of a circle can be calculated with the radius and central angle using the arc length formula.
Arc length = ∅/360 × 2πr
Given that pizza is 15 inches the slice has an arc length of 21.5 inches along the crust.
Use the formula above to calculate the value:-
Arc length = ∅/360 × 2πr
21.5 = ∅/360 × 2π ( 7.5 )
∅ = ( 21.5 x 360 ) / 2π ( 7.5 )
∅ = 164 degrees
Therefore, the approximate measurements of the central angle of the slice of pizza Charles cut will be 164 degrees. The correct option is B.

The length of a rectangle is increased by 10% while its breadth is decreased by 10%.
Determine, if any, the percentage change in its area.
Answer:
the new area is 1% smaller.
Step-by-step explanation:
the area of a rectangle is length times breadth.
let's call them a and b
Area = a × b
now, a is increased by 10%. that means it is multiplied by 11/10.
because 100% means the whole thing, 1% means a 1/100th part of the whole. and 10% then means 10 times the 1/100th part of 10 × 1/100 = 10/100 = 1/10
if then simmering increases by 10% it means that it is the original 100% plus 10%.
so, it is 100/100 + 10/100 = 10/10 + 1/10 = 11/10
therefore the new length is
a(new) = a(old)×11/10
in exactly the same way, when the breadth is reduced by 10% we get then
breadth(new) = breadth(old)×9/10
so, Area(new) = a(new)×b(new) = a(old)×11/10 × b(old)×9/10
remember, Area(old) = a(old)×b(old)
so, Area(new) = a(old)×b(old) × 11/10 × 9/10 =
= Area(old) × 11/10 × 9/10 =
= Area(old) × 99/100
that means the new area has lost compared to the old area 1/100th of its size. 1/100th = 1%
Write the equation of the parabola in vertex form.
vertex(2,1),points (1,-4)
F(x)=?
Step-by-step explanation:
The general vertex form is given by
[tex]y = a {(x - h)}^{2} + k[/tex]
where (h, k) is the vertex and a is a constant. So we can write the y as
[tex]y = a {(x - 2)}^{2} + 1[/tex]
To find the value of a, substitute the point (1, -4)
-4 = a(1 - 2)^2 + 1
or a = -5
Therefore, the vertex form of the parabola is
[tex]y = - 5 {(x - 2)}^{2} + 1[/tex]

11. The student council is comparing prices for their semi-formal dance. They compare banquet. Hall A charges $40 per person. Hall B charges $20 per person plus $500 fixed fee. Write an equation to represent the relationship between the total cost and the number of people, if the variables are defined as follows:
Answer:
TC (A) = 40x , TC (B) = 500 + 20x
Step-by-step explanation:
Let the number of students be = x
Hall A Total Cost
Relationship Equation, where TC (A) = f (students) = f (x) 40 per person (student) = 40x
Hall B Total Cost
Relationship Equation, where TC (B) = f (students) = f (x) 500 fix fee & 20 per person (student) = 500 + 20x

consider this equation tan(theta)=-5/3
if theta is an angle in quadrant II what is the value of sin(theta)
Answer:
B 5√34 / 34
Step-by-step explanation:
tan ∅ = opp/adj
In quad II
tan ∅ = 5 / (-3)
---------------------
hyp^2 = 5^2 + (-3)^2
hyp^2 =25 + 9 = 34
hyp = √34
---------------------------
sin ∅ = opp/hyp
sin ∅ = 5/√34
Rationalizing
sin ∅ = 5√34 / 34
Consider this equation [tex]tan(\theta)=-5/3[/tex]. if theta is an angle in quadrant II the of [tex]sin \theta = \dfrac{5\sqrt{34}}{{34} }[/tex].
What are the trigonometric ratios?Trigonometric ratios for a right-angled triangle are from the perspective of a particular non-right angle.
In a right-angled triangle, two such angles are there which are not right-angled(not of 90 degrees).
The slanted side is called the hypotenuse.
From the considered angle, the side opposite to it is called perpendicular, and the remaining side will be called the base.
Consider this equation
[tex]tan(\theta)=-5/3[/tex]
B 5√34 / 34
if theta is an angle in quadrant II what is the of sin(theta)
[tex]tan(\theta) = \dfrac{\text{Length of perpendicular}}{\text{Length of base}}[/tex]
In quadrant II
tan ∅ = 5 / (-3)
[tex]hyp^2 = 5^2 + (-3)^2\\hyp^2 =25 + 9 = 34\\hyp = \sqrt{34}[/tex]
[tex]\sin(\theta) = \dfrac{\text{Length of perpendicular}}{\text{Length of Hypotenuse}}[/tex]
[tex]sin \theta = \dfrac{5}{\sqrt{34} }[/tex]
Rationalizing
[tex]sin \theta = \dfrac{5\sqrt{34}}{{34} }[/tex]

A triangle has sides with lengths of 5 m, 4 m, and 3 m . Is it a right triangle?
Answer:
Yes.
Step-by-step explanation:
A triangle is a right triangle if the sides satisfy the Pythagorean Theorem, or:
a² + b² = c².
So input the values.
a² + b² = c²
3² + 4² = 5²
9 + 16 = 25
25 = 25
The triangle with sides 3 m, 4 m, and 5 m is a right triangle.
Answer:
Yes, it's a right triangle.
Step-by-step explanation:
We can use the Pythagorean theorem to help.
The theorem states that if a triangle is right, [tex]a^{2} + b^{2} = c^{2}[/tex].
C is the longest side of the right triangle or the hypotenuse.
A and b are the other 2 sides
5 is the greatest so that must be [tex]c[/tex].
4 and 3 are [tex]a[/tex] and [tex]b[/tex]. (It doesn't matter which is a and which is b)
Plug in the numbers:
[tex]4^2 + 3^2 = 5^2[/tex]
Solve:
16 + 9 = 25
25 = 25
This triangle is a right triangle!
