Answer:
16pi or 50.2
Step-by-step explanation:
formula for area of a circle is pi * radius squared. Since the diameter is 8 you divide that by 2 to get 4 and you square it so it becomes 16. Then you multiply it by pi or 3.14 to get 50.24 and then you round.
is 3(x + 2) and 5x + 6 both the answer 6 , which one is not 6 or are they both not 6

What is an equation of the line that passes through the points (3,1) and (-3, – 7)?
Put your answer in fully reduced form.
Answer:
y = 4/3x - 3
Step-by-step explanation:
Use rise over run to find the slope, (y2 - y1) / (x2 - x1)
Plug in the points:
(y2 - y1) / (x2 - x1)
(-7 - 1) / (-3 - 3)
-8 / -6
= 4/3
Now, plug in the slope and a point into y = mx + b to get the equation:
y = mx + b
1 = 4/3(3) + b
1 = 4 + b
-3 = b
Plug in the slope and y intercept into the equation:
y = 4/3x - 3
So, the equation is y = 4/3x - 3

A home building company purchases 24 acres of land and divides it into 1/2-acre plots for sale. How many 1/2-acre plots will be for sale?
Answer:
48
Step-by-step explanation:
This is a division problem.
You need to divide 24 by 1/2.
24 / 1/2 = 24/1 / 1/2 = 24/1 * 2/1 = 48/1 = 48
Answer: 48
You can also do it this way.
Each acre is the same size as 2 half-acres.
1 acre = 2 half-acres
Multiply both sides of the equation above by 24.
24 * 1 acre = 24 * 2 half-acres
24 acres = 48 half acres

Step-by-step explanation:
Anne Kates house is 20c. She had just made a fresh cup of tea (100c). Five minutes after she made her mad scientist nephew came in,stuck a thermometer in the cup and announced that the tea was now only 70c Write the possible equation with asymptotes
Answer:
The possible equation is; T(t) = 20 + 80·[tex]e^{(-0.094 \cdot t)}[/tex]
The horizontal asymptotes is Lim(t → ∞), T → 20°C
The vertical asymptote is Lim(t → 0) T → 100°C
Step-by-step explanation:
The given parameters are;
The temperature of the house = 20°C
The initial temperature of the tea = 100°C
The temperature of the tea after 5 minutes = 70°C
From Newton's law of cooling, is given as follows;
[tex]T(t) = T_s + (T_0 - T_s) \cdot e^{k \cdot t}[/tex]
[tex]\dfrac{dT}{dt} = -k(T - T_a)[/tex]
Where;
T(t) = The temperature after time, t =
[tex]T_s[/tex] =The room temperature = 20°C
T₀ = The initial temperature of the tea = 100°C
k = Constant
T(5) = 70°C, therefore, we have;
[tex]70 = 20 + (100 - 20) \cdot e^{k \cdot 5}[/tex]
50/80 = [tex]e^{k \cdot 5}[/tex]
5·k = ㏑(5/8)
k = ㏑(5/8)/5 ≈ -0.094
Therefore, the possible equation is given as follows;
T(t) = 20 + 80·[tex]e^{(-0.094 \cdot t)}[/tex]
The asymptotes are Lim(t → ∞), T → 20°C and Lim(t → 0) T → 100°C
Steve is playing a carnival game. He wants to win a prize, but he thinks he has about a 20% chance of winning. He uses the expression 0.2t to calculate the number of games he will need to play in order to win a prize.
If he plays the game 12 times, about how many times can he expect to win?
Answer:50%
Step-by-step explanation:
Steve's expected times of winning in 12 trials is about 2 times.
What is probability?Probability is the chance of occurrence of a certain event out of the total no. of events that can occur in a given context.
The winning chance of Steve is 20% or 0.2.
We know, We know The expected value, also known as the expectation, average, is a generalization of the weighted average in the field of probability theory.
Informally, the anticipated value is the arithmetic mean of a significant number of outcomes of a random variable that were independently chosen.
Therefore, If he plays the game 12 times the number of times he is expected to win is,
= 12×0.2.
= 2.4 Or 2 times.

What is an Absolute value function?An absolute value function is a function that gives positive value for a number or variable. It has a V shaped graph, it is also called as a modulus function.
The absolute function is y = | -x +7| +-4
The v shaped curve has a vertex and it can be determined by following method.
The value of the x coordinate is determined by equating the modulus to 0, the point at which the modulus is zero.
-x +7 = 0
Adding -7 to both sides.
-x = -7
x = 7
The value of y at this point is the y coordinate of the vertex.
y = 0 +4
y = 4
(x,y) = ( 7,4)

which make an angle 45 degree with x axis in negative direction and passes through a point (- 3, 2)
9514 1404 393
Answer:
y = -x -1
Step-by-step explanation:
The slope of a line is the tangent of the angle it makes with the x-axis. If you want an angle of -45°, then you need a line with a slope of m = tan(-45°) = -1.
Then the y-intercept is ...
b = y -mx
b = 2 -(-1)(-3) = 2 -3 = -1
So, the slope-intercept equation is ...
y = mx + b
y = -x -1
