f(g(x)) = 1, 4, 5, 3, 2

g(f(x)) = 5, 2, 4, 1, 3

Step-by-step explanation:

To find f(g(x)), locate g(x) in the third column (labeled g(x)). Use that value as x in the first column, then read f(x) from the second column.

Example: f(g(1)) = f(2) = 1

To find g(f(x)), locate f(x) in the second column (labeled f(x)). Use that value as x in the first column, and read the corresponding g(x) from the third column.

Example: g(f(1)) = g(2) = 5

This parabola opens to the left. P. O A. True O B. False

sesenic [268]

Answer:

True.

Explanation:

We take the analogy from the graph of y = ax^2

When y = x^2, the parabola opens upward (towards the positive y-axis). However, when the parabola is y = -x^2, it opens downward (towards the negative y-axis).

In a similar way, when we have x = ay^2, the parabola opens towards the positive x-axis ( towards the right). However, if we have x = -ay^2, then the parabola opens towards the negative x-axis ( towards the left).

Therefore, by comparison, x = - 1/8 y^2, opens to the left, and the correct option to choose is 'True'.

Zack and Dave each bought some coins from jerry online. Dave bought 5 more coins than Zack bought

Lubov Fominskaja [6]

Answer & Step-by-step explanation:

number of Dave's coins = number of Zack's coins + 5

The question is asking to find the difference in prices paid (thus "more"), completely unrelated to the number of coins Zack bought as these two numbers are independent of one another. The difference in price can be found by simply multiplying the cost of one coin by 5.

Marco walked 27/100 kilometer to the park. then he walked 3/10 kilometer to the library. What fraction of a kilometer did he wal

liubo4ka [24]

Answer:57/100

Step-by-step explanation:

First, convert 3/10 into hundreths to get a denominator equal to the other:

3/10 km = 30/100km

Add the numerators: 27+30=57

Place numerator over common denominator: 57/100

If you want to place 9 3/4 inch towel bar in the center of a door that is 27 1/2 wide, how much space will be on each side of th

marysya [2.9K]

The answer is $11 \frac{5}{6}$ inches

Step 1. Subtract length of the door from the width of the door:
$27 \frac{1}{2} - 9 \frac{3}{4} = \frac{55}{2} - \frac{39}{4} =\frac{110}{4} - \frac{39}{4}= \frac{71}{4}$

Step 2. You want the same space to be on each side of the bar. So, divide the difference from step 1 by 2:
$\frac{71}{4} : 2 = \frac{71}{4} : \frac{2}{1} =\frac{71}{4} * \frac{1}{2}= \frac{71}{6} = \frac{66+5}{6}= \frac{66}{6}+ \frac{5}{6}=11 \frac{5}{6}$

Fill in the gaps in this sequence: -8, -19, -30, _ , _. (Geometric and arithmetic sequences)

gavmur [86]

-8, -19, -30, -49 , -60

Step-by-step explanation:

Here we have the following sequence :

-8, -19, -30, _ , _

First term of sequence is -8 .
Second term of sequence is -19 : $-8-11 = -19$
Third term of sequence is -30 : $-19-11 = -30$
Fourth term of sequence is : $-30-11 = -49$
Fifth term of sequence is : $-49-11 = -60$

Following sequence was an AP( Arithmetic Progression ) with first term as -8 i.e. $a = -8$ and common difference $d = -11$ having general equation as : $-8 -11n$ .
