Which of the following represents the value of the nearest side? Round to the nearest tenth.
I think it’s b I’m currently learning the same thing in my class
Answer:
The answer is A. 2.0
Step-by-step explanation:
One of the angles is a right angle, because x is the tangent of that circle. The other radius is 1.5, since all radius are equal to each other. Then you use the Pythagorean theorem (a²+b²=c²). C is always the hypotenuse. The hypotenuse in this triangle is the 1.5 + 1 line. A and b can be changed within each other. I put A = 1.5, B = x, and C = 2.5. My equation was 1.5²+x²=2.5². Remember the formula can also be x²+1.5²=2.5² as well. Then you solve the equation you just made. You multiply everything by each other, because of the ² (I forgot the name of it, hehehe). You will get 2.25+x²=6.25. Then you subtract 2.25 to both side. x²= 4. Then you square root both sides to make x by itself. x=2. That's how you get 2 as your answer
comeplete the table for the following function
y = (1/3)
graph the function and describe what the graph looks like
The correct answer is C. The graph of the function [tex]y = (1/3)^x[/tex] decreases from left to right, exhibiting exponential decay as x increases.
To complete the table for the function [tex]y = (1/3)^x[/tex], we need to substitute the given values of x into the equation and calculate the corresponding values of y.
Let's start by substituting -3 into the equation:
y = (1/3)^(-3)
y = 1/(1/3)^3
y = 1/1/27
y = 27
Next, let's substitute -1 into the equation:
y = (1/3)^(-1)
y = 1/(1/3)^1
y = 1/(1/3)
y = 3
Then, let's substitute 0 into the equation:
y = (1/3)^0
y = 1
After that, let's substitute 1 into the equation:
y = (1/3)^1
y = 1/3
Lastly, let's substitute 2 into the equation:
y = (1/3)^2
y = 1/9
Therefore, the completed table is as follows:
x | -3 | -1 | 0 | 1 | 2 | 3
y | 27 | 3 | 1 | 1/3 | 1/9 | 1/27
To graph the function y = (1/3)^x, we plot the points from the completed table on a graph. The graph of this function is an exponential decay curve that starts at (0, 1) and decreases as x increases. The curve is steeper for larger x values and approaches the x-axis as x approaches infinity.
In terms of the given options, the correct answer would be C. The graph of the function decreases from left to right.

Which unit would you use to measure the amount of milk in a half-gallon carton?
mL
g
cm
L
Answer would be D which is L
Answer:
L
Step-by-step explanation:
Most people prefer to use a unit of measurement that gives a number they can easily visualize, usually between 0.1 and 1000.
You wouldn't use centimetres, because that is a unit of length, and grams are a unit of mass.
The amount of milk in a half-gallon carton is about 2 L or 2000 mL, so you would measure the milk in litres (L).

If you flip a coin 4 times, what is the best prediction possible for the number of times it will land on tails?
Answer:
2
Step-by-step explanation:
Each time you flip a coin, there is a 50% change of it landing on tails. So half the time you should get a tails.
Half of 4 is 2, so you will likely get 2 tails.
Final answer:
When you flip a coin 4 times, the best prediction for the number of tails is 2, based on the equal 50-50 chance for heads or tails on each toss. However, you may actually get any number of tails from 0 to 4 due to randomness.
Explanation:
If you flip a coin 4 times, the best prediction for the number of times it will land on tails can be determined by understanding probability. Each coin flip represents an independent event with a 50-50 chance of landing on either heads or tails. Therefore, over a small number of flips, such as 4, it is expected that you will get tails approximately half the time. However, it is possible to see any combination of heads and tails.
When considering all the possible outcomes of flipping a coin 4 times:
4 heads, 0 tails (HHHH)
3 heads, 1 tail (HHHT, HHTH, HTHH, THHH)
2 heads, 2 tails (HHTT, HTHT, HTTH, THHT, THTH, TTHH)
1 head, 3 tails (HTTT, THTT, TTHT, TTTH)
0 heads, 4 tails (TTTT)
Given that each of these outcomes is equally likely, the prediction would be 2 tails because it is the average outcome. However, it is important to recognize that while 2 tails is the most likely single outcome, any number of tails between 0 and 4 is possible due to the randomness of each flip.
Which of the following data represents an actual probability?
A computer randomly generates 6 out of 100 numbers.
An observer notes the number of pepperoni, cheese, vegetarian pizzas are ordered out of 100 orders.

Show your work!
6(x+0.4) 3(2x+0.8)
Answer:
Yes
6(x+0.4) is equivalent to 3(2x+0.8)
Step-by-step explanation:
Given in the questions two expressions
6(x + 0.4)
3(2x + 0.8)
We will apply distributive law
It is a law relating the operations of multiplication and addition, stated symbolically
a(b + c) = ab + ac6(x + 0.4)
= 6(x) + 6(0.4)
= 6x + 2.4
3(2x + 0.8)
= 3(2x) + 3(0.8)
= 6x + 2.4
Since both equations when expanded have same answers, hence they are equivalent
How could you correctly rewrite the equation 4(10+5)=6(12-2) using the distributive property?
Answer:
[tex]40 +20 = 72 -12\\\\60 = 60[/tex]
Step-by-step explanation:
If we have an expression in the following way:
[tex]c(a + b)[/tex]
So the distributive property says that:
[tex]c(a + b) = ca + cb[/tex]
In this case we have the expression:
[tex]4(10 + 5) = 6(12-2)[/tex]
Therefore we can rewrite it as:
[tex]4 * 10 + 4 * 5 = 6 * 12 -2 * 6[/tex]
Then we have left:
[tex]40 +20 = 72 -12\\\\60 = 60[/tex]
4*10+4*5=6*12-6*2
40+20=72-12
60=60

Answer:
3/2
Step-by-step explanation:
mm,m
Based on the calculations below, the slope of this graph is equal to: C. 2/3.
In Mathematics and Euclidean Geometry, the slope of any straight line can be determined by using the following mathematical equation;
Slope (m) = (Change in y-axis, Δy)/(Change in x-axis, Δx)
Slope (m) = rise/run
[tex]Slope(m)=\frac{y_2-y_1}{x_2-x_1}[/tex]
By substituting the given data points (0, -2), and (3, 0) into the formula for the slope of a line, we have the following;
Slope of graph = (0 - (-2))/(3 - 0)
Slope of graph = (0 + 2)/(3 - 0)
Slope of graph = 2/3
Based on the graph, the slope is the change in y-axis with respect to the x-axis, and it is equal to 2/3.

The population of a city in 2005 was 18,000. By 2010 the city's population had grown to 45,000. Economists have determined that the population growth follows an exponential model. If they are correct, what is the projected population for 2015?
Step-by-step explanation:
First we have to find percent change by doing change/original
To find change: 45000-18000=27000
Now divide by original. 27000/18000=1.5
The change was 150 percent. Now we multiply 45000 by 150 percent to get the projected population for 2015.
45000*1.5=67500 people
Brainliest? :)
Projected population for 2015 using exponential growth model is 112,500, calculated with initial population of 18,000 and growth rate.
To determine the projected population for 2015 using an exponential growth model, we need to identify the growth rate and use it to extrapolate the population.
The exponential growth model can be represented as:
[tex]\[ P(t) = P_0 \times e^{rt} \][/tex]
Where:
- [tex]\( P(t) \)[/tex] is the population at time [tex]\( t \)[/tex]
- [tex]\( P_0 \)[/tex] is the initial population (in 2005)
- [tex]\( r \)[/tex] is the growth rate
- [tex]\( t \)[/tex] is the time in years since the initial population was measured
First, we need to find the growth rate [tex](\( r \))[/tex]. We can use the data provided from 2005 to 2010:
[tex]\[ P_0 = 18000 \][/tex]
[tex]\[ P(5) = 45000 \][/tex]
Using these values in the formula:
[tex]\[ 45000 = 18000 \times e^{5r} \][/tex]
Now, let's solve for [tex]\( r \)[/tex]:
[tex]\[ \frac{45000}{18000} = e^{5r} \][/tex]
[tex]\[ 2.5 = e^{5r} \][/tex]
Taking the natural logarithm of both sides:
[tex]\[ \ln(2.5) = 5r \][/tex]
Now, divide by 5:
[tex]\[ r = \frac{\ln(2.5)}{5} \][/tex]
Now, we have the growth rate [tex]\( r \)[/tex]. We can use this rate to project the population for 2015 [tex](\( t = 10 \) years)[/tex]:
[tex]\[ P(10) = 18000 \times e^{\frac{\ln(2.5)}{5} \times 10} \][/tex]
Now, calculate this:
[tex]\[ P(10) = 18000 \times e^{\ln(2.5) \times 2} \][/tex]
[tex]\[ P(10) = 18000 \times e^{\ln(2.5^2)} \][/tex]
[tex]\[ P(10) = 18000 \times e^{\ln(6.25)} \][/tex]
[tex]\[ P(10) = 18000 \times 6.25 \][/tex]
[tex]\[ P(10) = 112500 \][/tex]
So, the projected population for 2015 is 112,500.
Sally's soccer team won 68% of the games they played. if they won 17 games, how many did they play?
Answer:
Step-by-step explanation:
Let the number of games played be x. 68% of x comes out to 17 games.
Then 0.68x = 17. Mult. both sides by 100: 68x = 1700.
Divide 68 into 1700 to obtain x, the number of games played: x = 25
The team plays in 25 games.

Find the perimeter of the larger flag.
Again, scale factor is 12 / 4 = 3.
So Perimeter = 16 * 3 = 48.
The perimeter of the larger flag, which is a square with each side measuring 8 inches, is 32 inches. This is calculated by multiplying the side length by 4, as a square has four sides.
Explanation:Finding the Perimeter of a Larger SquareTo find the perimeter of the larger flag, which resembles a larger square, you need to know the length of one of its sides. Since the problem states that the dimensions are twice that of a smaller square, first, determine the side length of the smaller square. If the side length of the larger square is 8 inches, obtained by scaling up the smaller square's side length by a factor of 2 (4 inches x 2 = 8 inches), you can find the perimeter by multiplying the side length of the larger square by 4 (since a square has four sides).
The calculation for the perimeter of the larger square is as follows: 8 inches x 4 = 32 inches. Therefore, the perimeter of the larger flag is 32 inches.
