Answer:
points A, B and D are all in the same plane but not all are on the same line
Step-by-step explanation:
points A, C, D are all collinear which means they must also be coplanar
Answer:
a) x = 128 degrees
b) Angle APD is the arc angle, which is equal to the central angle x subtended by the arc. Therefore angle APD = 128 degrees (and not 116 degrees)
Step-by-step explanation:
Given:
attached diagram
ABC is a straight line
Solution:
a) Find x
ABC is a straight line
angle ABD = supplement of CBD = 180-CBD = 180-116 = 64 degrees.
x is the central angle of the arc APD
so angle ABD is the inscribed angle which equals half of the arc angle =>
angle ABD = x/2 = 64 degrees
Solve for x
x/2 = 64
x = 2*64
x = 128 degrees
b.
Angle APD is the arc angle, which is equal to the central angle x subtended by the arc. Therefore angle APD = 128 degrees (and not 116 degrees)
Answer:
The answer is 1.
Step-by-step explanation:
Answer: 
Step-by-step explanation:
Given :
re - writing the equation , we have
we need to find the value of a and b for which -2<x < 4 , this means that the roots of the quadratic equation are -2<x < 4.
The formula for finding the quadratic equation when the roots are known is :
- sum of roots(x) + product of root = 0
sum of roots = -2 + 4 = 2
product of roots = -2 x 4 = -8
substituting into the formula , we have:
, which could be written in inequality form as
comparing with , it means that :
If I had to choose a business to start off with I would start a lemonade stand With cookies
First let's do the lemonade Side Let's say I put $100 into the business And it cost a dollar per lemon $5 for 10 lb of sugar It takes about five lemons about and a pound of sugar to make one batch that makes about 20 cups of Lemonade Each cup of lemonade for cost me roughly $0.50 I would then sell Each cup of lemonade for $0.75 and make a 5 profit Now let's talk about the cookie portion of the business You have to get milk flour sugar and salt Together that cost maybe $10 per batch Of 50 cookies Which cost roughly $0.20 to Make You can sell them at with a profit of $0.05 for $0.25 After $25 Prophet.So overall you will make roughly $30
