Answer:
No Solution
Step-by-step explanation:
perimeter
2√6 - √15 = 4.9-3.9 = 1
-3√3 = -5.19 you can't have a negative length.
and because of that the answer is no solution to both perimeter and area.
if the teacher was just oddly trying to have you show what you know
P = 1+1+ -5.2 - 5.2 = -8.2
A 1x -5.2 = -5.2

Find a formula for the general term an of the sequence, assuming that the pattern of the first few terms continues. (Assume that n begins with 1.)
{1, 7, 13, 19, 25, . . . }
Answers
Answer:
the formula is a_n = 6n - 5
Step-by-step explanation:
The formula is
Given that
{1, 7, 13, 19, 25, . . . }
The difference between the numbers is
7 - 1 = 6
13 -7 = 6
19 - 13 = 6
a = 1
d = 6
Now the formula is
a_n = a + (n - 1)d
= 1 + (n - 1)6
= 1 + 6n - 6
= 6n - 5
So, the formula is a_n = 6n - 5

how do we solve?
Answers
Answer:
7/12
Step-by-step explanation:
We cannot add fractions without the same denominator. 4 does not equal 6
ok
2/6 is the same as 4/12 because we multiply proportionately
we multiply the numerator and denominator by the same factor
2/6 x 2/2 = 4/12
now 1/4 is the same as 3/12 because we multiply by 3x3
(realize something we are not changing the value of the fraction. 2/2 is the same as 1 and 3/3 is also the same as 1)
now they have the same denominator
4/12 + 3/12+ = 7/12

Answer:
B. 136
Step-by-step explanation:
∆ABC is similar to ∆EDC, therefore the ratio of their corresponding side lengths would be the same.
Thus:
AC/EC = AB/ED
(144 - x)/x = 51/3
(144 - x)/x = 17/1
Cross multiply
(144 - x)*1 = 17*x
144 - x = 17x
144 - x + x = 17x + x
144 = 18x
Divide both sides by 18
144/18 = 18x/18
8 = x
x = 8
✔️AC = 144 - x
Plug in the value of x
AC = 144 - 8
AC = 136
A right circular cone is undergoing a transformation in such a way that the radius of the cone is increasing at a rate of 1/2 inches per minute while the height of the cone is decreasing at a rate of 1/3 inches per minute. At the moment the radius of the cone is 2 in and the height of the cone is 1/3 in, find the rate of change of the volume of the cone. Simplify your answer and be sure to include units with your answer.
Answers
Answer:
The volume is decreasing at the rate of 1.396 cubic inches per minute
Step-by-step explanation:
Given
Shape: Cone
[tex]\frac{dr}{dt} =\frac{1}{2}[/tex] --- rate of the radius
[tex]\frac{dh}{dt} =-\frac{1}{3}[/tex] --- rate of the height
[tex]r = 2[/tex]
[tex]h = \frac{1}{3}[/tex]
Required
Determine the rate of change of the cone volume
The volume of a cone is:
[tex]V = \frac{\pi}{3}r^2h[/tex]
Differentiate with respect to time (t)
[tex]\frac{dV}{dt} = \frac{\pi}{3}(2rh \frac{dr}{dt} + r^2 \frac{dh}{dt})[/tex]
Substitute values for the known variables
[tex]\frac{dV}{dt} = \frac{\pi}{3}(2*2*\frac{1}{3}* \frac{1}{2} - 2^2 *\frac{1}{3})[/tex]
[tex]\frac{dV}{dt} = \frac{\pi}{3}(\frac{4}{3}* \frac{1}{2} - \frac{4}{3})[/tex]
[tex]\frac{dV}{dt} = \frac{\pi}{3}(\frac{4}{3}(\frac{1}{2} - 1))[/tex]
[tex]\frac{dV}{dt} = \frac{\pi}{3}(\frac{4}{3}*- 1)[/tex]
[tex]\frac{dV}{dt} = -\frac{\pi}{3}*\frac{4}{3}[/tex]
[tex]\frac{dV}{dt} = -\frac{22}{7*3}*\frac{4}{3}[/tex]
[tex]\frac{dV}{dt} = -\frac{22}{21}*\frac{4}{3}[/tex]
[tex]\frac{dV}{dt} = -\frac{88}{63}[/tex]
[tex]\frac{dV}{dt} =-1.396in^3/min[/tex]

Step-by-step explanation:
You park your car, and start walking west on Robinson Street at a speed of 2.1 m/s. After 16 minutes, you turn left. It really is a beautiful day out, and so you slow your speed to 1.1 m/s and continue walking to the south on Rosalind Avenue for another 12 minutes. At this point, you realize that you have a library book on hold at the downtown branch, and decide to make a quick detour to pick it up. You turn right and jog west at a speed of 3.4 m/s for 28 seconds to cross the street before the light changes. At this point, how far (in meters) are you from your car?
Answers
Answer:
The distance is 2077.77m
Step-by-step explanation:
Given
Represent speed with s and time with t
[tex](s_1, t_1) = (2.1m/s,16min)[/tex] ---- Left
[tex](s_2, t_2) = (1.1m/s,12min)[/tex] --- South
[tex](s_3, t_3) = (3.4m/s,28sec)[/tex] ---- Right
Required
How far are you from your car?
[tex]distance=speed * time[/tex]
To solve this question, I will use the attached image to illustrate the movement.
First, we calculate distance AB
Using: [tex](s_1, t_1) = (2.1m/s,16min)[/tex] ---- Left
[tex]d_1 = s_1 * t_1[/tex]
[tex]d_1 = 2.1m/s * 16min[/tex]
Convert min to secs
[tex]d_1 = 2.1m/s * 16*60s[/tex]
[tex]d_1 = 2016m[/tex]
[tex]AB = 2016m[/tex]
Next, we calculate the distance BC
Using: [tex](s_2, t_2) = (1.1m/s,12min)[/tex] --- South
[tex]d_2 = 1.1m/s * 12min[/tex]
[tex]d_2 = 1.1m/s * 12*60s[/tex]
[tex]d_2 = 792m[/tex]
[tex]BC = 792m[/tex]
Next, we calculate distance CD
Using: [tex](s_3, t_3) = (3.4m/s,28sec)[/tex] ---- Right
[tex]d_3 = 3.4m/s * 28s[/tex]
[tex]d_3 = 95.2m[/tex]
[tex]CD = 95.2m[/tex]
The distance between you and the car is represented as AD.
Considering triangle AOD, we have:
[tex]AD^2 = AO^2 + OD^2[/tex]
Where:
[tex]AO = AB - BO[/tex]
and
[tex]BO = CD[/tex]
So:
[tex]AO = AB - CD = 2016m - 95.2m[/tex]
[tex]AO = 1920.8m[/tex]
[tex]OD = BC[/tex]
[tex]OD = 792m[/tex]
The equation becomes:
[tex]AD^2 = AO^2 + OD^2[/tex]
[tex]AD^2 = 1920.9^2 + 792^2[/tex]
[tex]AD^2 = 4317120.81m^2[/tex]
[tex]AD= \sqrt{4317120.81m^2[/tex]
[tex]AD= 2077.76822817 m[/tex]
[tex]AD= 2077.77 m[/tex] --- approximated

This is quite easy actually. If you look on the right you see that the exterior angle next to x is 144 degrees. We know that a straight line is 180 degrees so to find x we can do 180 = x + 144.
Answer:
∠ACB = 36°
∠ABC = 60°
Step-by-step explanation:
∠ACB = 180 - 144 (Linear Pair)
therefore, x = 36°
∠ABC = x + 24°
∠ABC = 36 + 24
∠ABC = 60°

If the correlation coefficient in an ordinary least squares regression = 1.00, then A. all the data points must fall exactly on a straight line with a positive slope. B. all the data points must fall exactly on a straight line with a slope that equals 1.00. C. all the data points must fall exactly on a horizontal straight line with a zero slope. D. all the data points must fall exactly on a straight line with a negative slope.
Answers
Answer: Option A is correct.
Step-by-step explanation:
The correlation coefficient(r) is a statistical measure that computes the strength of the relationship between two variables.It lies between -1 and 1.
If the correlation coefficient in an ordinary least squares regression = 1.00.
That indicates that there is a perfect relationship between the variables.
i.e. all the data points must fall exactly on a straight line with a positive slope. .
[when r is positive, the slope of the line is positive].
i.e. option A is correct.
All the data points must fall exactly on a straight line with a positive slope. Then the correct option is A.
What is the correlation coefficient?It is a statistical concept that helps in establishing a relation between the predicted and actual value obtained in a statistical experiment. It explains the exactness of the predicted value and actual value.
