Answer/Step-by-step explanation:
1. Side CD and side DG meet at endpoint D to form <4. Therefore, the sides of <4 are:
Side CD and side DG.
2. Vertex of <2 is the endpoint at which two sides meet to form <2.
Vertex of <2 is D.
3. Another name for <3 is <EDG
4. <5 is less than 90°. Therefore, <5 can be classified as an acute angle.
5. <CDE is less than 180° but greater than 90°. Therefore, <CDE is classified as an obtuse angle.
6. m<5 = 42°
m<1 = 117°
m<CDF = ?
m<5 + m<1 = m<CDF (angle addition postulate)
42° + 117° = m<CDF (Substitution)
159° = m<CDF
m<CDF = 159°
7. m<3 = 73°
m<FDE = ?
m<FDG = right angle = 90°
m<3 + m<FDE = m<FDG (Angle addition postulate)
73° + m<FDE = 90° (Substitution)
73° + m<FDE - 73° = 90° - 73°
m<FDE = 17°
Not sure what that means
I guess it must be
-8x^2 + 3xy + (-9x) + (-3)
and
2ab + (-5ab^2) + (-9a^2b)
Answer:
its 53
Step-by-step explanation:
160 divided by 3 (the amount of feet in a yard) = 53
Answer:
21.16
Step-by-step explanation:
Starting from the theory we have the following equation:
Using the data supplied in the exercise, we have subtracting the mean and dividing by the standard deviation:
solving for "c", knowing that fi is a tabulating value:
therefore the value of c is equal to 21.16
Answer:
Step-by-step explanation:
To find the zeros, set y=-4(x - 3)2 + 8 = 0. Then -4(x - 3)^2 = -8, and:
4(x - 3)^2 = 8. Dividing both sides by 4 yields (x - 3)^2 = 2.
Taking the square root of both sides yields x - 3 = ±2, so that
x = 3 ±2, or x = 5 and x = 1. These are the zeros. The correct interpretatioon is A: where the daily profit is $0.
