Find BDC.
BDC=
Step-by-step explanation:
<NDC=<NCD (Given)
<NCD=35°.
<CAN=<DBN (Given)
<DBN=50°.
therefore, <CND = 180-35-35=110.
and <CND and <DNB are linear pair.
<CND+<DNB=180°
<DNB=180-110
<DNB=70.
therefore, <BDN = 180-50-70 = 60.
therefore, <BDC= 35°+60°=95°.
hope this helps you.
Answer:
angle BDC= 95°............
Answer the following questions about the graph:
a. What are the labels on each axis?
b. What is happening for the first 5 minutes of Annabelle's climbing session?
What is your reason for saying that?
c. When was Annabelle climbing fastest? How do you know?
d. What is happening from 5 to 7 minutes? What is your reason for saying
that?
Hours. C(t)
Answer:
C=149+25t
Step-by-step explanation:
Since the total cost is C you would set it all equal to C.
Then the one time cost for parts was 149 so you have to add that in.
And $25 per hour would be multiplied by t because t is the number of hours.
Answer:
Hazel have 200 baseball cards in her collection.
Step-by-step explanation:
Let the number of card Hazel's have be x.
Given:
Hazel brother have = 80 cards
Also Given:
The number of cards in 4/5 of Hazel's baseball card collection is equal to twice the number in her brother's collection.
It means that 4/5 times of hazel card is equal to 2 multiplied with the number of cards hazel brother have.
Framing in equation form we get;
Hence Hazel have 200 baseball cards in her collection.

d. 120
Answer:
Option b is correct
30 is the average rate of change of f(x) over the interval [1, 5]
Step-by-step explanation:
Average rate of change (A(x)) of f(x) over interval [a, b] is given by:
....[1]
As per the statement:
Given the function:
We have to find the average rate of change of f(x) over the interval [1, 5].
At x = 1
then;
At x= 5
then;
Substitute these given values in [1] we have;
⇒
⇒
Therefore, the average rate of change of f(x) over the interval [1, 5] is, 30
Answer:
Its b.30
