Find the circumference of the object. Use 3.14 or 22/7 for Pi. Round to the nearest hundredth if necessary.
Answer:
[tex]43.96 \text{ in}[/tex]
Step-by-step explanation:
The equation for circumference is:
[tex]C=2\pi r[/tex]
Using the diagram, we can conclude that the radius of the object is 7 in.
We can substitute this value in for the equation (Note that I will use 3.14 for π):
[tex]C=2\pi r\\C=2*3.14*7\\C=14*3.14\\C=43.96\text{ in}[/tex]
What are the coordinates when reflected over line y=2 if the starting point is (-3,0)?
Answer:
The x value wouldn't change because its being reflected in the y axis.
As y=2 is two away from the current line y=0 then the new coordinate for y will be two away from y=2 again.
So the coordinate would be x = - 3, y=4. (-3, 4)
Write the exponential function.
Answer:
[tex]f(x) = 10*(b)^x[/tex]
Step-by-step explanation:
exponential function : [tex]y=a*(b)^x[/tex]
where a = y intercept and b = factor ( what you multiply by )
looking at the table the y intercept is at (0,10) so a = 10
so we now have y = 10 * (b)^x
to find the factor we simply plug in one of the ordered pairs.
note that the ordered pair chosen does not effect the outcome
i chose (2,250)
we have y = 10 * (b)^x
(x,y) = (2,250)
250 = 10 * (b)^2
divide both sides by 10
25 = b^2
take the square root of both sides
5 = b
the final equation would be f(x) = 10 * (b)^x

Answer:
1. -3/6 is negative, because it descends by 3 and goes over by 6.
2. My first answer literally gives the keyword negative, therefore it's a negative line because it has a negative slope.
1. -8/0 is undefined, because there is a rise but there is no run, which also means that it's a:
2. vertical line
1. -5/-10 simplifies to 5/10 or 1/2, which is positive because it rises by 5(or 1) and runs over by 10(or 2).
2. Thus, this means that it's a positive line since it has a positive slope.
1. 0/-2 is zero, because when you actually solve the equation it'll equal 0.
2. This means that it'll have a horizontal line since there is no rise but there is a run only.

Justin is two years older than one third Tyler's age.
Reese is four years younger than two times Justin's age.
Find Justin and Reese's age if Tyler is 63 years old
Answer:
soo umm i think justin is 23 but reese is..d e d (unless i understood the problem wrong loll)
Step-by-step explanation:
let t be tylers age
let j be justin's age
let r be reese's age
j = 2 + 1/3t
r = 2j - 4
j = 2 + 1/3(63)
j = 2 + 21
j = 23
justin is 23 years old when tyler is 63
r = 2(63) - 4
r = 126 - 4
r = 122

Answer:
4 m
Step-by-step explanation:
The circumference of a circle is the product of π and the diameter.
C = πd
12.56 m = 3.14d
d = 12.56 m/3.14 = 4 m

A basketball coach claims that the team's players commit, on average, no more than 10 fouls per game. Let µ represent the team's average number of fouls per game. Another coach thinks that these players create more fouls. What is the null hypothesis, H0, for this situation?.
The null hypothesis, [tex]\rm H_{0}[/tex] for the given situation in the question, will be
[tex]\rm H_{0}:\mu\leq 10[/tex]
What will be the null hypothesis for the given data?For finding the null hypotheses we will follow the data given in the question
The null hypothesis, [tex]\rm H_{0}[/tex] is the hypothesis of no difference and as such, it always has an equality sign;
=, ≤, ≥
In order to identify the null we lookout for specific keywords that will provide us with information on the type of inequality sign.
In this situation, the coach claims that the average number of fouls committed per game is no more than 10.
Since µ represents the team's average number of fouls per game, this statement can be written in mathematical symbols as;
[tex]\mu\leq 10[/tex]
That is [tex]\mu[/tex] is less than 10 and the average number of fouls committed per game is less than 10.
This statement will be our null hypothesis since it contains an equality sign.
[tex]\rm H_{0}:\mu\leq 10[/tex]
Thus null hypothesis, [tex]\rm H_{0}[/tex] for the given situation in the question, will be
[tex]\rm H_{0}:\mu\leq 10[/tex]

Answer:
3 2/3
Step-by-step explanation:
To solve mixed fractions, you multiply the denominator with the whole number and add the number on top and write it in numerator,
Example: 2 1/3
Here, 3 is denominator so multiply by the whole number ahead 3*2=6 and add with numerator, 6+1=7 and finally write on numerator, 7/3
Therefore, 2 1/3 = (3*2+1)/3=7/3
Now,
The given problem is,
6 1/3 - 2 2/3
19/3 - 8/3

The height of a plant over time is shown in the table below. using a logarithmic model, what is the best estimate for the age of the plant when it is 19 inches tall? plant height t, time in months h, height in inches 1 18 2 18.21 3 18.33 4 18.42 5 18.48 6 18.54 10 months 14 months 16 months 28 months
The age of the plant if the height of the plant is 19 inches is 28 months.
What is logarithmic regression?The general equation for logarithmic regression is given by the formula,
y = a+b ln(x)
where y is the dependent variable, x is the independent variable, and a and b are the constants.
Let y be the height of the plant and x be the age of the plant.
If we plug in any two of the points in the equation, to get the value of a and b.
x = 1 and y = 18[tex]18=a+b\rm \ ln(1)\\\\18=a+0\\\\a = 18[/tex]
x = 2 and y = 18.21[tex]18.21=18+b\rm \ ln(2)\\\\0.21=b\ ln(2)\\\\b = 0.3[/tex]
Thus, the logarithmic expression represents the relationship between the age of the plant and the height of the plants is y=18+0.3 ln(x).
Now, if the height of the plant is 19, inches than the age of the plant is,
[tex]y=18+0.3\rm\ ln(x)\\\\19 =18+0.3 ln(x)\\\\x = 28.03\approx 28[/tex]
hence, the age of the plant if the height of the plant is 19 inches is 28 months.

∆x = (4--4)=8
∆y = (7--3)= 10

distance is given by;
d² = (∆y)²+ (∆x)²
d = √((∆y)²+ (∆x)²)
d = √((4+4)² + (7+3)²)
d = √((8²) + (10²))
