The slope of the line tangent to the polar curve r = 3θ at the point where θ = π/2 is; Undefined
What is the slope of the line tangent?
By converting into parametric equations, we have;
x(θ) = r(θ) cos θ = cos 3θ cos θ
y(θ) = r(θ) sin θ = cos 3θ sin θ
By product rule;
x'(θ) = -sin 3θ cos θ - cos 3θ sin θ
x'(π/2) = -sin 3(π/2) cos (π/2) - cos 3(π/2) sin (π/2)
x'(π/2) = 0
y'(θ) = -sin 3θ sin θ + cos 3θ cos θ
y'(π/2) = -sin 3(π/2) sin (π/2) + cos 3(π/2) cos (π/2)
y'(π/2) = 1
The slope m of the curve is gotten from;
m = y'(π/2)/x'(π/2)
m = 1/0
Thus the slope is undefined

when activated phospholipase c cleaves an inositol phospholipid, what happens to the small signaling molecules the enzyme produces?
When activated phospholipase c cleaves an inositol phospholipid, Both inositol 1,4,5-trisphosphate (IP3) and diacylglycerol are retained in the membrane.
What occurs if phospholipase C is activated?When G protein is said to be stimulated, it is known to often activates phospholipase C.
Note that phospholipase C. is siad to hook up to a phospholipid known as phosphatidylinositol 4,5- biphosphate that is often seen in the plasma membrane lipid bilayer. The outcome of thses two hookup is the production of two products known as inositol 1,4,5 triphosphate (IP3) and diacylglycerol (DAG).

Target profit is $100,000; total fixed costs are $120,000, and total variable costs are $500,000, the markup percentage is
The markup percentage to the variable cost using the variable cost method is 40%.
What is markup percentage?
The markup percentage to the variable cost using the variable cost method can be obtained by dividing the addition of the target profit and total fixed cost by the total variable cost as follows.
We know that:
Total fixed cost
= Fixed overhead costs + Fixed selling and administrative costs
= $120,000 + $50,00
= $170,000
The markup percentage to the variable cost
= (Target profit + Total fixed cost) / Total variable cost
= ($100,000 + $170,000) / $675,000
= $270,000 / $675,000
= 0.40, or 40%.

Which example shows an interaction between the urinary system and the circulatory system?
The main interaction between the urinary system and the circulatory system is both of the following parts of the human body work for the kidney.
The human body is the collection of many systems like the cardiovascular system for the heart, the urinary system for filtering the body, the circulating system for movement, and so on. All these functions help the body to regulate the smooth functioning of the body.
When the blood enters the kidney through arteries they go through the tiny capillaries that are seen in the urinary system. The blood entered into the kidney later moves to nephrons, where the blood is purified with the help of filters.
The waste that is obtained after the purification of the blood is then transferred to the vital substance that absorbs the bloodstream. It helps the body to manage and control the level of pressure in the blood.
Here the job of the heart is to simultaneously send the oxygenated blood all around the body and send the unwanted, discharged waste to the kidney where it helps to observe the required elements from the waste and transpose it to the urinary system.
The main work of the circulating system is to transpose the oxygenated blood to every part of the cell and provide them with sufficient nutrients.
From this system it is understandable that the similarities between circulatory and urinary system is both of the parts functions to remove waste from the body.

Use a direct proof to show that the sum of two odd integers is even
Below is the proof that the sum of two odd numbers is always even.
How to prove that the sum of two odd numbers is even?
First, remember that an even number is written as:
x = 2*n
Where n is an integer number.
While an odd number will be written as:
y = 2*n + 1
Now, let's say that we have two odd numbers:
A = 2k + 1
B = 2n + 1
If we add these we get:
A + B = (2k + 1) + (2n + 1) = 2k + 2n + 2 = 2*(k + n + 1)
And k + n + 1 is an integer number, then we can write:
k + n + 1 = N
So we get:
A + B = 2N
Then the sum of A and B is an even number.
Thus, we proved that for the sum of any two odd numbers, the outcome will always be even.

So I turned homeschool not too long ago and you do need to the the SAT/ACT depending on which community college it is?

Explanation:
Answer: college admissions is handled very similarly for homeschoolers as it is for traditionally schooled students. In fact, many admissions offices actively seek out homeschoolers. Admissions officers evaluate each student within the context of his/her own background and the opportunities they've had. There are, however, a few differences regarding how homeschoolers submit certain application materials. As a homeschooled student, your parent or primary teacher is responsible for creating your high school transcript and for sending it to your colleges. Parents have a few different options for going about this:
1. Working under an umbrella school that produces official transcripts and diplomas
2. Creating their own transcript and diploma
3. Enlisting a service that specializes in transcript and diploma creation
4. Joining a homeschool group that produces professional transcripts and diplomas
Explanation:
Your transcript should include all of the following information:
Your name, the name of your homeschool (if applicable), address, and phone number
Your high school course list ordered by year (grades 9-12)
The institution where each class was taken (i.e. homeschool, online institution, community college)
The grade scale being used in your homeschool
Your overall GPA
Credits given per course (listed per semester and per year)
Expected graduation date
Parent signature with a date
Homeschoolers do not need a GED or a diploma to apply to college or qualify for financial aid; you just have to declare that your homeschool education meets state law requirements. Most homeschooled students choose not to take the GED if they have valid transcripts, as colleges will place the most emphasis on your transcript and standardized test scores. If you’re homeschooled through an online academy, virtual school, or organized homeschool program then they will award your diploma according to their own standards. If you’re homeschooled independently by your parents, then your parents have the option of issuing you a diploma if your transcripts indicate you’ve met the basic state requirements for graduation. When filling out the FAFSA, be sure to check “homeschooled” when it asks for your high school completion status. Even if your homeschool is administered through an umbrella organization, you should still check “homeschooled” instead of “high school diploma” to avoid any delays in the processing of your application.

The ratio of hybrid cars to gasoline-powered cars in the parking lot of a local office building is 3:11. if there are 280 cars in the lot and one is to be selected at random to get the reserved parking space nearest the building, find the probability the car selected is a hybrid. express your answer as a fraction.
Answer:
The probability that it will be a hybrid is 21.4%.
Probability is the ratio of number of occurrences to total number of possible occurrences.
Given a total number of 280 cars. The number of hybrid cars is gotten by using the ratio.
Number of hybrid cars = (3/14) * 280 = 60 cars
Probability of picking a hybrid car = Number of hybrid car/total number of cars = 60 cars / 280 cars = 21.4%
Therefore the probability that it will be a hybrid is 21.4%.

Hence, The total distance in miles the student ran during these 10 days is 38.75 miles.
What is distance?Distance is the total length between two points.
To calculate the total distance in miles covered by the student, during these 10 days ran, we use the formula below
Formula:
D = d₁T+d₂T........... Equation 1Where:
D = Total distanced₁ = distance covered each day in the first 5 daysd₂ = distance covered each day in the next 5 daysFrom the question,
Given:
d₁ = 3[tex]\frac{1}{2}[/tex]miles = 7/2 milesT = 5 Daysd₂ = 4[tex]\frac{1}{4}[/tex] miles = 17/4 milesSubstitute these values into equation 1
D = [(7/2)×5]+[(17/4)×5]D = 17.5+21.25D = 38.75 milesHence, The total distance in miles the student ran during these 10 days is 38.75 miles.
