Answer 1
Answer:

Answer:

Isosceles

Step-by-step explanation:

If BD is an altitude, it splits triangle ABC into 2 triangles.  It is also a median, so it splits the angle ABC into 2 congruent angles.  Angle ABD and CBD are congruent.  That means that angles A and C are congruent. This is true because the 2 angles at D are both right angles.  Because of this, side AB and side CB are congruent.  That means that this is an isosceles triangle.

Which tables contain correct pairs of input and output values for the function ? Select all the correct answers.

Answers

The correct answer for the question that is being presented above is this one: "A rule is a function if each element in the domain goes to exactly one element in the range."

The following tables that contain correct pairs of input and output values for the function are the: 
(1) 
Input (x) -1.6 0.4 2.2 3.7
Output f(x) -5.5 2.5 6.75 10.75

(2)
Input (x) 1.1 2.4 5.3 6.9
Output f(x) 4.25 7.5 11.75 17.25

Answer:

domain (0,1,3,5,6) range (-20,-16,-8,0,4) function f(x)=4-4x

domain (-2,-1,0,3,4) range -13,-8,-3,12,17) function f(x)=5x-3

domain (-4,-3,0,2,4) range (-40,-20,0,20,40) function f(x)=10x

domain (-3,-2,-1,2,6) range (0.5,0,-1.5,3,2) function f(x)=3/x+1.5

A patient receives 150 cc of medication in an IV drip over 4 hours. What is the rate per hour of this dose?

Answers

The average rate is 150 cc/4 hrs=37.5 cc per hour.
37.5 cc per hour you just have to divide 150cc/4 = 37.5 cc

Determine whether the sequence is arithmetic or geometric.sequence 1: 32, 16, 0, –16, ...
sequence 2: 32, 16, 8, 4, ...
which of the following statements are true regarding sequence 1 and sequence 2.

sequence 1 is arithmetic and sequence 2 is geometric.
both sequences are arithmetic.
both sequences are geometric.
sequence 2 is arithmetic and sequence 1 is geometric.

Answers

S1.
32, 16, 0, -16, ...
It's an arithmetic sequence:
a_1=32;\ d=16-32=-16\n\na_n=a_1+(n-1)d\n\na_n=32+(n-1)\cdot(-16)=32-16n+16=48-16n

S2.
32, 16, 8, 4, ...
It's a geometric sequence:
a_1=32;\ r=16:32=(1)/(2)\n\na_n=a_1r^(n-1)\n\na_n=32\cdot\left((1)/(2)\right)^(n-1)

Answer: sequence 1 is arithmetic and sequence 2 is geometric.

The running time for movie A is 33 mins more than twice the running time for movie B. If the running time for movie A is subtracted from triple the running time for movie B, the result is 57 mins. find the running time for each movie..Movie A-
Movie B-

Answers

X is the running time for movie A and y the running time for movie B
X = 2y + 33
3y - × = 57
x- 2y = 33
-× + 3y = 57  => y = 90
=> x 33 + 180 = 213
use what they tell you to create the equations 

 a=33+2b  & 57=3b-a

for this to work we need to substitute a variable to get rid of it. 
look at 
          57=3b-a (lets switch it around s that the equation reads "a=")
          57+a=3b
          a=3b-57 (this is our new equations)

so now we know that 
a=33+2b & a=3b-57
so we can write 33+2b=3b-57. we have now "gotten rid" of "a"

SOLVE FOR B 

33+2b=3b-57  (get variable alone)
33= 3b-2b-57  (subtract and add accordingly)
33= b-57
33+57=b
90=b     (this means that movie b is 90 long)

SOLVE FOR A

you can plug "b" into any of the original equations.

a=33+2b 
a=33+2(90)
a=33+180
a=213

CHECK

plug "a" into any of the original equations to find "b" if b=90 then you know you've done it right 

213=33+2b
213-33=2b
180=2b
180/2=b
90=b

hope this helps :)

Which of the functions below have period 2pi? Check all that apply. A. y = tan x B. y = sec x C. y = cot x D. y = csc x

Answers

Answer:

Option B and D are correct that is y=secx and  y=cscx  respectively.

Step-by-step explanation:

We have been given four functions:

CaseA:

y=tanx

\text{Period oftanx is} \pi

Hence, A is correct.

CaseB:

y=secx

\text{Period of secx is} 2\pi

Hence, B is correct.

CaseC:

y=cotx

\text{Period of cotx is} \pi

Hence, C is not correct.

CaseD:

y=cscx

\text{Period of cscx is} 2\pi

Hence, D is correct.
