Answer:
Turtle = 11 m / min
Snail = 1 m / min
Total approach speed = 12 m/min
360 m / (12 m/min) = 30 min
Separation is 30 min at assumed speed of 1 m/min
But we know the separation is 40 min
So turtle moves at 3/4 * 11 m / min = 33 m/ 4 min
Snail moves at 3/4 * 1 m /min = 3/4 m / mi
Total approach speed = (33 + 3) / 4 = 9 m / min
So in 40 min
9 m / min * 40 min = 360 m
(Leaving out those units, they approach at 12 * unit of speed)
So the unit of speed has to be 360 m / 40 min = 9 m / min

if I am right plz give brainliest
please help. will give brainliest! review the table of values for function p(x). what is lim (x -14) p(x), if it exists? (table and answer options pictured)
Answer:
DNE
Step-by-step explanation:
The the given table, we have;
As x approaches -14 from the left, at x = -14.001, p(x) = 1.96
[tex]\lim \limits _{x \to -14^{-}} p(x) = 1.96[/tex]
As x approaches -14 from the right, at x = -13.999, p(x) = 1.97
[tex]\lim \limits _{x \to -14^{+}} p(x) = 1.97[/tex]
The value of p(x) when x = -14 is [tex]\lim \limits _{x \to -14} p(x)[/tex] = Undefined, or is not definable, therefore, p(x) Does Not Exist (DNE) when x = -14, and we have;
[tex]\lim \limits _{x \to -14} p(x)[/tex] Does Not Exist, DNE.

At the Fisher farm, the weights of zucchini squash are Normally distributed. Which standardized weight represents the top 10% of the zucchinis?
Find the z-table here.
–1.64
–1.28
1.28
1.64
Thus, the standardized weight which represents the top 10% of the zucchinis from the z-table for the fisher farm is 1.28.
How to get the z scores?If we've got a normal distribution, then we can convert it to standard normal distribution and its values will give us the z score.
[tex]Z = \dfrac{X - \mu}{\sigma}[/tex]
Here, X is sample, is μ mean and is σ standard deviation.
At the Fisher farm, the weights of zucchini squash are Normally distributed.
For the normal distribution let the value of mean is 0 and standard deviation 1. Thus,
[tex]Z = \dfrac{X - \mu}{\sigma}\\Z = \dfrac{X - 0}{1}\\Z=X[/tex]
For the top 10% of the zucchinis, the value of α is 0.9. From the table for this value the z score is,
[tex]Z=X=1.28[/tex]
Thus, the standardized weight which represents the top 10% of the zucchinis from the z-table for the fisher farm is 1.28.

If a1=4 and an =2an-1 – 1 then find the value of a4.
The value of [tex]a_{4} = 37[/tex].
Here,
The value of [tex]a_{1} = 4[/tex]
And, [tex]a_{n} = 2 a_{n-1} -1[/tex]
We have to find value of [tex]a_{4}[/tex].
What is Sequence?
A sequence is a collection of elements that are arranged according to a specific pattern.
Now,
The value of [tex]a_{1} = 4[/tex]
And, [tex]a_{n} = 2 a_{n-1} -1[/tex]
Then to find value of [tex]a_{4}[/tex], we can find [tex]a_{2} , a_{3}[/tex] as;
[tex]a_{2} = -2(a_{1} ) - 1\\a_{2} = -2(4) - 1\\a_{2} = -9[/tex]
And,
[tex]a_{3} = -2(a_{2} ) - 1\\a_{3} = -2(9) - 1\\a_{3} = -19[/tex]
Hence, the value of [tex]a_{4}[/tex] is;
[tex]a_{4} = -2(a_{3} ) - 1\\a_{4} = -2(-19) - 1\\a_{4} = 37[/tex]
Therefore, The value of [tex]a_{4} = 37[/tex].

Tricia made a circular mat from a square piece of cloth.
-Picture-
Which is closest to the circumference, in inches, of the circular mat?
A. 44 inches
B. 88 inches
C. 154 inches
D. 616 inches
Answer:
The circumference of the circle has a measurement of 44 inches
Step-by-step explanation:
From the question, as we can see, the given length represents the diameter of the circle
To get the circumference of the circle, we use the formula for the circumference
this is;
C = pi * d
in this case, d = 14 in
Thus, we have it that;
C = pi * 14 = 14 * 22/7 = 44 in

the triangle is obtuse
Answer:
obtuse scalene
Step-by-step explanation:
An obtuse triangle is any triangle that has an obtuse angle. An obtuse angle is one that measures greater than 90 degrees. (so we know that this is obtuse)
A scalene triangle is one which have all three sides of a triangle of different lengths and all three angles of different measures (the three sides are diffrent so this applies)
In geometry, an isosceles triangle is a triangle that has two sides of equal length (this does not apply)
