Answer:
The terminal point is (1, 0) ⇒ D
Step-by-step explanation:
In the unit circle, Ф is the angle between the terminal side and the positive part of the x-xis.
The terminal point on the positive part of the x-axis is (1, 0),which means Ф = 0° or 360° and cosФ = 1, sinФ = 0The terminal point on the positive part of the y-axis is (0, 1),which means Ф = 90° and cosФ = 0, sinФ = 1The terminal point on the negative part of the x-axis is (-1, 0),which means Ф = 180° and cosФ = -1, sinФ = 0The terminal point on the negative part of the y-axis is (0, -1),which means Ф = 270° and cosФ = 0, sinФ = -1In a unit circle
∵ Ф = 2π radians
∵ 2π radians = 360°
→ By using the 1st rule above
∴ The terminal point is (1, 0)

Choose the proper rationale. "In the compound interest equation, time
Answer:
The correct answer is:
c. Time is an exponent while the other units are factors.
Explanation:
In the compound interest formula, time is the exponent.
Since it is the exponent, this tells us how many times the base is multiplied by itself. As such, it has a larger effect on the answer than any other piece of the equation.

Kim spent $33 on a magazine and
some candy bars. If the magazine
cost $5 and each candy bar cost
$4, then how many candy bars did
Answer:
Seven candy bars.
Explanation:
Suppose the number of candy bars purchased is x
The questions say he bought A magazine, means one magazine
the equation is:
4x + 5 = 33
4x = 33 – 5
4x = 28
x = 7
Kim bought 7 candy bars.
Hope this helps! :)
Your company makes game parts using 3-D printers. One customer wants a circular game coin that is 2.0 centimeter across and 0.5 centimeters thick. You need to estimate the of plastic you will need for each arch of 50 coins. How many cubic centimeters is that, rounded up if necessary to be a multiple of 10 cubic centimeters?
Answer:
80 cm^3
Step-by-step explanation:
The computation of the number of cubic centimeters rounded up to 10 cubic centimeter is shown below
For any type coin,
r = d ÷ 2
= 2 ÷ 2
= 1 cm
l = 0.5cm
For making 1 coin, the plastic required would be = Volume of coin
= πlr^2
= 3.14 × 0.5 × 1 × 1
= 1.57cm^3
Now For 50 coins,
Plastic needed is
= 50 × 1.57
= 78.5cm^3
= 80 cm^3
A bird goes from a higher location to a lower location at a rate of 3 meters per second. Which equation models the change in the bird's position at 120 seconds?
a. 120(-3) = -360
b. 120 x 3 = 360
c. (-120)(-3) = -360
d. 120(-3) = 360
Answer:
D
Step-by-step explanation:
We know that every second the bird's position lowers by 3(-3) so the equation for it is option D

A map has a scale of 1 in : 14 mi. If
Victoria and Kumba are 2 in apart on the
map, then how far apart are the real cities?
Answer:
28 miles
Step-by-step explanation:
Since 1 inch represents 14 miles, we can find the actual distance by multiplying 14 by 2:
14(2)
= 28
So, the real cities are 28 miles apart.
Answer:
SoluTion :-Let the unknown distance be x
[tex] \tt \dfrac{1}{14} = \dfrac{2}{x} [/tex]
By cross multiplication
[tex] \tt \: 14 \times 2 = 1 \times x[/tex]
[tex] \tt \: 28 = x[/tex]
ThereforeThe far apart distance will be 28 miles.
A 60 ounce glass bottle of juice sells for $4.20 while a 1.5 liter of the same juice sells in a plastic bottle for $3.06. Compare the unit prices of the juice for the two containers. (1 liter is approximately 34 ounces)
The answer is letter b. $4.20 / 60 ounce is the rate for the glass bottle while $3.06 / 51 ounces is the rate for the plastic one. Simplified, the glass bottle is $0.07 / ounce while the plastic bottle is $0.06 / ounce.

A school chorus has 90 sixth-grade students and 75 seventh-grade students. The music director wants to make groups of performers, with the same combination of sixth- and seventh-grade students in each group. She wants to form as many groups as possible. If the largest group was formed, how many students of each grade level would be in each group?
Answer:
The music director can form a total of 15 groups
6 Sixth grade students per group
5 Seventh grade students per group
Step-by-step explanation:
Sixth grade students = 90
Seventh grade students = 75
Find the highest common factor of 75 and 90
90 = 1, 2, 3, 5, 6, 9, 10, 15, 18, 30, 45, 90.
75 = 1, 3, 5, 15, 25, 75
The highest common factor of 75 and 90 is 15
Therefore, the music director can form a total of 15 groups
Sixth grade students per group = 90 / 15
= 6 Sixth grade students per group
Seventh grade students per group = 75 / 15
= 5 Seventh grade students per group

Plz help!! Write the name of each quadrilateral and find the area
Answer:
Step-by-step explanation:
1. Rectangle: This is because all the angles are at right angles and the length is more than the breadth.
Area = Length X breadth = 6m X 5.1 m =30.6 metre square
2. Kite: it has two equal pairs of sides adjacent to each other
Area =(BD X CE )/2 = (8 X 12) /2 = 48
3. Parallelogram: This is because it has two opposite sides that are parallel, and the angles are not 90 degrees.
Area = base X height = 5.7 X 8 = 45.6 metres square
4. Rectangle: This is because all the angles are at right angles and the length is more than the breadth.
Area = Length X breadth = 2 yd X 3.1 yd = 6.2 square yards
5. Trapezium: it has only one pair of sides parallel.
Area = 0.5 ( top side + bottom side ) X height = 0.5 (6+3 X 5) = 22.5
6. Kite: it has two equal pairs of sides adjacent to each other
Area =(EG X FH)/2 = (10 X 7) /2 = 35

The formula for the volume of a cone is v= 1/3 xr^2 h. The radius, r, of the cone may be expressed as
Answer:
r=√(3v)/(xh)
Step-by-step explanation:
the volume of a cone is given as
v= 1/3 xr^2 h. Then we need the radius, r, of the cone
v= 1/3 xr^2 h
Let us cross multiply we have
3v= xr^2h
Make r^2 subject of the formula we have
r^2= 3v/xh
Find the square root of bother sides we have
r=√(3v)/(xh)
the radius, r, of the cone can be expressed as r=√(3v)/(xh)

A small rectangle has a width of 4 feet and a length of 10 feet. A larger, similar rectangle has a length of 12 feet. What is the perimeter of the larger rectangle?
Answer: 33.6 feet
Step-by-step explanation:
Since the small rectangle has a width of 4 feet and a length of 10 feet. It simply means that the length is 2.5 times the width.
A larger, similar rectangle has a length of 12 feet. The width will be:
= 12 / 2.5
= 4.8 feet
The perimeter of the larger rectangle will then be:
= 2(Length + Width)
= 2(12 + 4.8)
= 2 × 16.8
= 33.6 feet
