Answer:
Based on the information given, we know that the domain of g is -20 ≤ x ≤ 5 and the range is -5 ≤ g(x) ≤ 45. We also know that g(0) = -2 and g(-9) = 6.
A. g(-4) = -11: This statement could be true or false, as there is not enough information to determine its validity.
B. g(0) = 2: This statement is false, since we know that g(0) = -2.
C. g(7) = -1: This statement could be true or false, as there is not enough information to determine its validity.
D. g(-13) = 20: This statement is false, since -13 is outside the domain of g (-20 ≤ x ≤ 5).
Step-by-step explanation:Therefore, the statement that could be true for g is A. g(-4) = -11 or C. g(7) = -1.
Let H: X – Y be a mapping. The set Y is called the
Let H: X – Y be a mapping. The set Y is called the codomain of the mapping H: X – Y.
In mathematics, a mapping or function H: X – Y is a relation between two sets, where the set X is called the domain and the set Y is called the codomain.
The mapping H assigns each element in X to a unique element in Y. The codomain of the mapping H is the set Y, which contains all the possible outputs that can be obtained from the mapping.
It represents the range of the mapping H and provides a reference set for the outputs of the function. The actual range of the function may be smaller than the codomain, depending on the elements in X that are mapped to.

Area:
Perimeter:
Carolyn will need 15 square units of carpet to cover her front room. Carolyn will need 16 units of skirting board to go around the sides of her front room.
To find the area of Carolyn's front room, we need to multiply the length by the width. In this case, the dimensions are given as 5 x 3, so the area is:
Area = length x width = 5 x 3 = 15 square units
To find the perimeter of the room, we need to add up the lengths of all four sides. Since the room is rectangular, opposite sides are of equal length. So, we can find the perimeter by adding twice the length and twice the width, which gives:
Perimeter = 2(length + width) = 2(5 + 3) = 16 units

The area of a circle is 36π centimeters. What is the circumference of a circle in terms of π.
Let u = - 7i + 7j v = 4i - i and w = - 9i Find 5u - (4v - w)
First, we need to simplify the expression inside the parentheses:
4v - w = 4(4i - i) - (-9i) = 16i - 4i + 9i = 21i
Now, we can substitute the values of u, v, and w into the expression:
5u - (4v - w) = 5(-7i + 7j) - (21i) = -35i + 35j - 21i = -56i + 35j
Therefore, the final result is -56i + 35j.
Answer:
-60i +39j
Step-by-step explanation:
You want the value of 5u -(4v -w) given ...
u = -7i +7jv = 4i -jw = -9iVector additionThese are added the way any polynomials are added. Like terms can be combined.
5u -(4v -w)
= 5(-7i +7j) -(4(4i -j) -(-9i))
= -35i +35j -(16i -4j +9i)
= -35i +35j -25i +4j
= -60i +39j

Encik Halim bought 108 lemons to sell at his grocery shop. He packed 3 lemons in small packets and sold at the price of RM6.80 per packet. If he made a total profit of RM88.20, calculate the price of each lemon bought by him.
Answer:
the price of each lemon bought by Encik Halim is RM1.45.
Step-by-step explanation:
Encik Halim bought 108 lemons and packed them into packets of 3 lemons each. So he made a total of 108/3 = 36 packets.
Let's assume that the cost of each lemon bought by Encik Halim is x RM.
The total cost of 108 lemons would then be 108x RM.
Encik Halim sold each packet at a price of RM6.80, so the total revenue he earned from selling 36 packets would be 36 x RM6.80 = RM244.80.
We are told that Encik Halim made a profit of RM88.20 from the sale of these packets, so his total cost would be:
Total cost = Total revenue - Profit
Total cost = RM244.80 - RM88.20
Total cost = RM156.60
We know that Encik Halim bought 108 lemons, so we can write:
Total cost = Number of lemons bought x Cost per lemon
RM156.60 = 108x
Therefore, the cost per lemon bought by Encik Halim is:
x = RM156.60/108
x = RM1.45
So the price of each lemon bought by Encik Halim is RM1.45.
After 8 years, Fabian earned $1430 in simple interest from a CD into which he
initially deposited $5500. What was the annual interest rate of the CD?
A. 0.48%
B. 4.8%
C. 0.325%
D. 3.25%
Answer:
D. 3.25%
Step-by-step explanation:
The formula for simple interest is:
I = Prt
where I is the interest earned, P is the principal, r is the annual interest rate, and t is the time in years.
We are given that:
I = $1430
P = $5500
t = 8 years
Substituting the values:
$1430 = $5500 * r * 8
Simplifying, we get:
r = $1430 / ($5500 * 8)
r = 0.0325 or 3.25%
Therefore, the annual interest rate of the CD is 3.25%.
