Answer: Program C allows students to earn a Mathematics degree (B.A. or B.S.) by combining courses in the Department of Mathematics with courses from one other department. In most areas of specializations, mathematical and/or quantitative courses in other departments are part of the math degree program. All Program C students take a minimum of five core math courses: Calculus I, Calculus II, Calculus III, Introduction to Linear Algebra, and a proofs course, usually either Introduction to Abstract Algebra or Fundamental Properties of Spaces and Functions I.

Have a nice day <3
After changing the unit of 144 inches into yards the number equivalent to 144 inches is 4 yards. Hence option (a) is true.
Given that,
Change the number 144 inches into yards.
Used the concept of measurement unit which stated that,
A measurement unit is a standard quality used to express a physical quantity. Also, it refers to the comparison between the unknown quantity with the known quantity.
Since we know that,
1 yards = 36 inches
1 inch = 1/36 yards
So, we can change the number 144 inches into yards,
1 inch = 1/36 yards
144 inches = 144/36 yards
= 4 yards
Therefore, 144 inches is equivalent to 4 inches.
Option (a) is true.

Make q the subject of the formula p = 2q2 .
Answers
Answer:
q = ± [tex]\sqrt{\frac{p}{2} }[/tex]
Step-by-step explanation:
Given
p = 2q² ( divide both sides by 2 )
[tex]\frac{p}{2}[/tex] = q² ( take the square root of both sides )
± [tex]\frac{p}{2}[/tex] = q
Answer:
q = +√p/2
Step-by-step explanation:
p = 2q²
divide both sides by 2 and root we get,
√p/2 = √2q²/2
√p/2 = q
q = +√p/2
Thus, q = +√p/2

Write the equation in standard form for a circle that has a diameter with endpoints (8,0) and (-8,0)
Answers
Answer:
x²+y² = 64
Step-by-step explanation:
The standard form of writing the equation of a circle is expressed as;
(x-a)²+(y-b)² = r² where;
(a, b) is the centre of the circle
r is the radius of the circle
Given the diameter of the circle with endpoints (8,0) and (-8, 0)
d = √(x2-x1)²+(y2-y1)²
d = √(-8-8)²+(0-0)²
d = √(-16)²
d = √256
d = 16
radius r = 16/2
r = 8
The centre of the circle will be the midpoint of the coordinates
M = (8-8/2, 0+0/2)
M = (0/2, 0/2)
M = (0,0)
Hence the centre is at (0,0)
Get the required equation
Recall that (x-a)²+(y-b)² = r²
Substitute the centre and the radius
(x-0)²+(y-0)² = 8²
x²+y² = 64
This gives the required equation

Find the approximate area of the lake whose shape is overlaid on the grid below. Each

Answer:
7.5 square miles
Step-by-step explanation:
Begin by counting the number of squares that the lake completely or almost completely covers. There are six of these, as indicated by an X. Then find the squares which are about half covered by the lake. These are indicated by a Y. There are three of these. The remainder of the squares that contain some portion of the lake are less than half covered, so we will not count them.
Irregular Object
1 square = 1 sq. mile
Each X counts as one square mile, and each Y counts as 0.5 (12) of a square mile.
(6 × 1) + (3 × 0.5) = 6 + 1.5 = 7.5
The area of the lake is about 7.5 square miles.
