BartSMP [9]3 years ago
7 0

This set notation really seems the hard way to exclude a single value. Anyway...

The domain doesn't include where the denominator is zero, 4x + 7 = 0,

x = -7/4

The range doesn't include the asymptotic value, which is

y=2x/4x = 1/2

So we need domain x ≠ -7/4 and range y ≠ 1/2

Answer: First choice

The triangle shown is translated up 5. What are the new coordinates of point C?
ehidna [41]

Answer:

(3,6)

Step-by-step explanation:

The triangle shown in figure is translated up 5

To find how coordinate of C

Original coordinate of C:(2,1),

Translation has two types: verbal and horizontal.

For verbal translation: either shift up or down

1. For up shift: add value in Y-cordinate  

2. For down shift: subtract value in y coordinate

• For horizontal translation: either shift left or right

I. For left shift: subtract value in x-cordinate

II. For right shift: add value in x-cordinate

C: (3,1)shift 5 unit up

So, add 5in y-cordinate

(3,1)→(3,1+5)

(3,1)→(3:6)

Hence, the new coordinate of point C is (3,6)

The formula v=√64h can be used to find the velocity v in feet per second of an object that has fallen h feet. Find the velocity
zhuklara [117]

Answer:

  B)  43.82 feet/sec

Step-by-step explanation:

Fill in the number and evaluate:

  v = √(64×30) = √1920 ≈ 43.82 . . . . ft/s

_____

Of course, √(64h) can be simplified to 8√h. You know that √30 lies between 5 and 6, so the velocity lies between 8·5 = 40 and 8·6 = 48. There is only one answer choice in that range.

Vernon's work for finding the value of x is shown below. Lines A C and B D intersect at point E. Angle A E D is (16 x + 8) degre
Marta_Voda [28]

Answer:

<em>No, he should have set the sum of ∠AED and ∠DEC equal to 180°, rather then setting ∠AED and ∠DEC equal to each other</em>

Step-by-step explanation:

Find the diagram attached

If line AC and BD intersects, then m<AED + m<DEC = 180 (sum of angle on a straight line is 180 degrees)

Given

m<AED = 16x+8

m<DEC = 76 degrees

16x + 8 + 76 = 180

16x + 84 = 180

16x = 180-84

16x = 96

x = 96/16

x = 6

Hence the value of x is 6

Hence the correct option is <em>No, he should have set the sum of ∠AED and ∠DEC equal to 180°, rather then setting ∠AED and ∠DEC equal to each other</em>
