The decay of 249 mg of an isotope is given by A=249e−0.015t , where t is time in years. Find the amount after 43 years.
Answer:
A≈676.2
Step-by-step explanation:
1. Exponentially solve equation
A=249e-0.0015t as t = 43 years (Unless conversion to seconds)
A≈676.2
2. Solve graphically = intersect = (43, 676.2) x axis is time y axis is amount.

Find the surface area of a sphere with a radius of 2√2 feet.
94.5 square feet
100.5 square feet
25.1 square feet
35.5 square feet
Answer: 100.5 square feet
Step-by-step explanation:
To find : surface area of sphere with radius of [tex]2\sqrt{2}feet[/tex]
The formula used to calculate surface area of sphere is = [tex]4\times \pi\times r^2[/tex]
where r is the radius of sphere.
Putting the values we get:
surface area of sphere = [tex]4\times 3.14\times (2\sqrt{2}feet)^2=100.5square feet[/tex]
Thus the surface area of a sphere with a radius of 2√2 feet is 100.5 square feet
Answer:
100.5 square ft

The sales tax in one town is 8%. So, the total cost of an item can be written as c+0.08c. What is the total cost of an item that sells for 12?
Answer:
12.96c
Step-by-step explanation:
Given the total cost of an item written as c+0.08c. To get the total cost of an item that sells for 12, we will write;
1 item = c+0.08c
1 item = 1.08c
For 12items;
12 = x
Divide both expressions
1/12 = 1.08c/x
1 * x = 12 * 1.08c
x= 12.96c
Hence the total cost of 212 items is 12.96c

Answer:
y = 7, x ≈ 9.9
Step-by-step explanation:
The remaining angle has to also be 45° which tells us we're working with an isosceles right triangle, or that y also has to be 7 (the same length).
Use the Pythagorean theorem for x.
a^2 + b^2 = x^2
7^2 + 7^2 = x^2
49 + 49 = x^2
x^2 = 98
x ≈ 9.9

A book store sells used paperbacks for 3.75 each you receive a 2$ discount if you spend at least $30 in the store. Write and solve an inequality that represents the least number of the paperbacks you must buy in order to get a discount.
Answer: x is less than or equal to 29.40
The minimum quantity of paperbacks you must purchase to receive a discount is represented by an inequality where x is less than or equal to 29.40.
Explain about the inequality?A connection that compares two numbers or other mathematical expressions inequitably is known as an inequality in mathematics. On the number line, size comparisons between two numbers are typically conducted.
A relationship between two expressions or values that is not equal to one another is referred to as "inequality" in mathematics.
Mathematicians utilize the greater than symbol, less than symbol , less than symbol, and not equal to symbol as the five inequality symbols.
Take from each side the same quantity. To both sides, add the same positive number. Add the identical positive value to both sides. Then, multiply both sides by the same negative number while flipping the sign.

Answer:
the second one.... ( 8,9 )
Step-by-step explanation:
the zero-product system is rlly easy to use....
it basically means to take each term and equal it to zero....
so for your equation it is....
( x - 9 ) ( x - 8 ) = 0
so you would write it as....
( x - 9 ) = 0
and
( x - 8 ) = 0
and then you solve them like this...
( x - 9 ) = 0
add 9 to both sides to get the variable by itself...
x= 9
( x - 8 ) = 0
add 8 to both sides to get the variable by itself....
x = 8
