What is the domain of the function represented by the graph?

Mathematics
1 answer:
dezoksy [38]2 years ago
8 0

Answer:  Choice C.  x \ge -3

============================================

Explanation:

The domain is the set of all allowed x inputs.

Here we see that x = -3 is the smallest x value possible as it is from the left-most point. The graph goes on forever to the right, so there is no largest x value. Effectively infinity is the largest x value even though infinity is not a number.

We can say the domain is -3 \le x < \infty which can be simplified to -3 \le x or x \ge -3

In short: x can be -3 or larger.

The measure of Angle A is 2x and Angle B is 60 when Angle A and Angles are supplementary angles. What is the value of x? A. 15 B
Anna35 [415]

Answer:

B) 60

Step-by-step explanation:

<u>Given:</u>

  • <A = 2x
  • <B = 60
  • <A and <B are supplementary angles (they add up to 180)

<u>Equation:</u>

<A + <B = 180

2x + 60 = 180

2x = 180 - 60

2x = 120

x = 60

You have 16 digs for your current volleyball season. There are 3 games left in the season. You want to break your previous recor
g100num [7]

Answer:

we must get more than 4 digs in the remaining 3 games break record of 20

Step-by-step explanation:

given data

current volleyball season = 16 digs

games left in the season = 3

previous record = 20 digs

solution

we consider here the number of digs  x that must get in the remaining 3 games to break your record

so for break  previous record of 20 digs, we have to get more than 20  

so 16 digs must add to x to greater than 20

x + 16  ≥ 20   ...............................1

so x will be

x ≥ 20 - 16

x ≥ 4  

so that we must get more than 4 digs in the remaining 3 games break record of 20

Solve for d.<br><br> 4d + 1 = 17<br><br> d =
forsale [732]

Answer:

4

Step-by-step explanation:

4d + 1 = 17

1 + 4d = 17

Move all terms containing d to the left, all other terms to the right.

1 + -1 + 4d = 17 + -1

0 + 4d = 17 + -1

4d = 17 + -1

4d = 16

d = 4

The ratio of boys to girls in a local choir is 7:10. If there are 35 boys in the choir, how many girls are there?
erica [24]

Answer:

50 girls

Step-by-step explanation:

Given data

We have the ratio as

7:10

The total part = 7+10= 17

let the number of boys and girls be x

applying the part to all method

7/17= 35/x

cross multiply

7x= 35*17

7x=595

x=595/7

x= 85

Hence the number of girls is

=85-35

=50 girls

If DA = 6 and MD = 4, what is the length of DK?
Leto [7]

Answer:

DK = 9

Step-by-step explanation:

In triangle AMD,

h² = p² + b²

or, h² = 6² + 4²

or, h²= 36 + 16

so, h² = 52

so, AM² = 52

Take x as reference angle,

cos²x = 16/52

Now,

In triangle, AMK,

Taking x as reference angle,

cos²x = b²/h²

cos²x = AM²/MK²

or, cos²x = 52/MK²

Now,

cos²x = 16/52 = 52/MK²

or,

16/52 = 52/MK²

or, 16MK² = 2704

or, MK² = 2704/16

or, MK² = 169

so, MK = 13

Now,

DK = MK - MD

or, DK = 13 - 4

so, DK = 9
