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.

Step-by-step explanation:
A Dilation is defined as a transformation in which the image and the pre-image have the same shape, but their sizes are different.
When the scale factor is greater than 1, the image obtained after the dilation is greater than the pre-image and it is an "Enlargement".
When the scale factor is is between 0 and 1, the image obtained after the dilation is smaller than the pre-image and it is an "Reduction".
In this case you know that the triangle ABC was dilated by this scale factor:
With the origin as the center of dilation.
Since:
It is a Reduction.
You can identify that the vertices of the triangle ABC are:
So you need to multiply the coordinates of each vertex of the triangle ABC by , in order to get the coordinates of the triangle A'B'C. Then, you get:

Answer:
19.7
Step-by-step explanation:
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

Answer:
Obstuse scalene
Step-by-step explanation:
Scalene - no sides are equal
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)
Hope this helps!

Find measure of angle 1
Jane incorrectly finds the volume of the cone using the following work. Explain Jan’s error and find the correct volume AND surface area. Show all work
Answer:
V=39.25. the height is not 6.25, 6.25 is the slope. you have to use Pythagoras theorem to find the height, then you can find the volume.
The surface area of the cone shown in the figure, for which Jane incorrectly finds the volume, is 74.33 cm².
What is of volume of cone?
Volume of cones the amount of quantity, which is obtained by the solid or object in the 3 dimensional space.
Volume of cone can be given as,
[tex]V=\dfrac{1}{3}\pi r^2h[/tex]
Here, (r) is the radius of the base of the cone and (h) is the height of the cone.
The height of the cone is 6.5 cm and the radius is 2.5 cm. Put the values in the above formula,
[tex]V=\dfrac{1}{3}\pi r^2h\\V=\dfrac{1}{3}\pi (2.5)^2(6.5)\\V=\dfrac{1}{3}\pi (6.25)^2(6.5)\\V=\dfrac{40.625\pi }{3}\\V\approx42.5\rm\;cm^3[/tex]
The surface area of cone can be find out by the following formula,
[tex]A=\pi r(r+\sqrt{h^2+r^2})[/tex]
Again put the values in this formula,
[tex]A=\pi \times2.5(2.5+\sqrt{(6.5)^2+(2.5)^2})\\A=\pi \times2.5(2.5+\sqrt{48.5})\\A=\pi \times2.5(2.5+6.96)\\A=\pi \times2.5(9.46)\\A=74.33\rm\; cm^2[/tex]
Thus, the surface area of the cone shown in the figure, for which Jane incorrectly finds the volume, is 74.33 cm².
