Step-by-step explanation:

f(g(x)) = 2(x-3)+7

=2x-6+7

=2x+1

Answer:

2x+1

Step-by-step explanation:

We know that g(x)= x-3

So f(g(x))= f(x-3)  

We put it in the equation :

f(x-3)= 2(x-3) +7 = 2x-6+7 = 2x +1

Answer:

Range: 0.07

Median: 0.145

Mode: none

Step-by-step explanation:

Range: largest #- smallest #

Median: middle number (when numbers are in order least to greatest) or when two are middle number you add them, and divide by two

Mode: most occurring number(s) (if there aren't any, no mode)—but if there are multiples such as 2 zeros and 2 ones then 0 and 1 would be the mode

Answer:

yes

because the descent of the ball is 32m per second

Step-by-step explanation:

To determine if the relationship is proportional, determine the descent of the ball per second

after 2 seconds = 64 / 2 = 32

after3 seconds = 96/3 = 32

after 4 seconds = 128 / 4 = 32

the relationship is proportional

Answer:

C. The temperature increase went down because it became cooler as the sun went down for the night

Step-by-step explanation:

It is natural to have high temperatures when the sun is up, and as dusk begin to set, the temperature of a place drops. L

Going by the above stated fact, to explain the hours after the peak increase in temperature, it is plausible to conclude that as the sun went down, it became cooler for the night. That's why we have the lowest temperature displayed on the graph between 10 PM to 11:59 PM.

Answer:

-4/5

Step-by-step explanation:

If you use the number line, after adding 3/5 you can see that it still doesn't make it positive but brings it up to -4/5 (Hope this helps)

Answer:

You subtract them:

3/5-7/5 (the plus disappears when faced with a minus)

-4/5

Given:

The function is:

[tex]f(x)=2x^2-14x+10[/tex]

The function g(x), the image of f(x) after a [tex]r_{y=x}[/tex] (reflection over the line y=x).

To find:

The function g(x).

Solution:

We have,

[tex]f(x)=2x^2-14x+10[/tex]

Substitute [tex]f(x)=y[/tex] in the given function.

[tex]y=2x^2-14x+10[/tex]

The function g(x), the image of f(x) after a [tex]r_{y=x}[/tex] (reflection over the line y=x). So, interchange x and y.

[tex]x=2y^2-14y+10[/tex]

Now, we need to find the value of y.

[tex]x=2(y^2-7y+5)[/tex]

[tex]\dfrac{x}{2}=y^2-7y+5[/tex]             [Divide both sides by 2]

[tex]\dfrac{x}{2}-5=y^2-7y[/tex]             [Subtract 5 from both sides]

Add both sides half of square of coefficient of y, i.e. [tex](\dfrac{-7}{2})^2[/tex], to make it perfect square.

[tex]\dfrac{x}{2}-5+(\dfrac{-7}{2})^2=y^2-7y+(\dfrac{-7}{2})^2[/tex]

[tex]\dfrac{x}{2}-5+\dfrac{49}{4}=y^2-7y+(\dfrac{7}{2})^2[/tex]

[tex]\dfrac{x}{2}-5+\dfrac{49}{4}=\left(y-\dfrac{7}{2}\right)^2[/tex]          [tex][\because (a-b)^2=a^2-2ab+b^2][/tex]

[tex]\dfrac{x}{2}+\dfrac{49-20}{4}=\left(y-\dfrac{7}{2}\right)^2[/tex]

Taking square root on both sides, we get

[tex]\pm\sqrt{\dfrac{x}{2}+\dfrac{29}{4}}=y-\dfrac{7}{2}[/tex]

[tex]\dfrac{7}{2}\pm\sqrt{\dfrac{2x+29}{4}}=y[/tex]

[tex]\dfrac{7}{2}\pm\dfrac{\sqrt{2x+29}}{2}=y[/tex]

[tex]\dfrac{7\pm \sqrt{2x+29}}{2}=y[/tex]

Substituting [tex]y=g(x)[/tex], we get

[tex]\dfrac{7\pm \sqrt{2x+29}}{2}=g(x)[/tex]

Therefore, the required function is [tex]g(x)=\dfrac{7\pm \sqrt{2x+29}}{2}[/tex].

Answer:

4.5

Step-by-step explanation:

The Interesecting Secants Theorem states that when two secant lines intersect each other outside a circle, the products of their segments are equal. A secant is a straight line that cuts a curve in two or more points, so this definitely applies here, as both AB and CB interesect the circle twice.

Using this theorem, we can say that 6*3=4*x, so 18=4*x and x=4.5

Answer:

x=57°

Step-by-step explanation:

the sum of the measures of the angles of a triangle add up to 180°.

it is given that there is a 33°, and a right angle which is 90°.

to find x:

x=180°-(90°+33°)

x=180°-123°

x=57°

Answer:

180° - 33° - 90° = 57°

x = 57°

Answer:

P(AUB)'=2/15

Step-by-step explanation:

According to the Question,

So, P(B)=1-P(B') ⇒ P(B)=1-(1/3) ⇔ P(B)=2/3

P(A∩B)=3/5 × 2/3 ⇒ P(A∩B)=2/5

Thus, P(AUB)= 3/5 + 2/3 - 2/5

P(AUB)=1/5 + 2/3

P(AUB)=(3+10)/15 ⇔P(AUB)=13/15

Answer:

1/15

Step-by-step explanation:

Step 1 find probability of pulling 1 pink marble

Like stated previously probability = # of favorable outcomes / # of possible outcomes

The favorable outcomes is what we want to happen

We want to pull a pink marble and there are a total of 3 pink marbles

So # of favorable outcomes = 3

To find the # of possible outcomes we simply find the number of marbles. There are a total of ten marbles

So probability of pulling one pink marble = 3/10

Step 2 find the probability of pulling another pink marble ( IMPORTANT NOTE: It says to find the probability of pulling 2 pink marbles if the first one is NOT put back before the second pull. this meaning that we must subtract 1 from the total # of marbles and 1 from the total # of pink marbles )

3 - 1 = 2

10 - 1 = 9

So after the first pull there would be 2 pink marbles out of 9 total marbles

So the probability of pulling a pink marble on the second pull is 2/9

Finally we multiply the two probabilities together to find our answer

3/10 * 2/9 = 1/15

Answer:

1.4, 1 1/8, 0.7

Step-by-step explanation:

1 1/8 is equal to 1.125 which it makes it less than 1.4 but more than 0.7.

Answer:

[tex]0.7, \frac{11}{8},1.4[/tex]

Step-by-step explanation:

In order to understand what numbers are greater and what numbers are smaller, we need to make them have the same common denominator. So firstly, we turn all of these numbers into fractions, and we get...

[tex]0.7 = \frac{7}{10}\\\\1.4 = \frac{14}{10}\\\\\frac{11}{8 }= \frac{11}{8 }[/tex]

Now we, need to find the least possible number divisible by 10 and 8, to find the least common denominator. And we get, that the least common denominator is 40, and knowing this, now we have to take each fraction and turn it into an equivalent fraction with the denominator of 40. So we do...

[tex]\frac{11}{8}= \frac{(11)(5)}{(8)(5)}= \frac{55}{40}\\\\\frac{7}{10} = \frac{(7)(4)}{(10)(4)} = \frac{28}{40} \\\\\frac{14}{10} = \frac{(14)(4)}{(10)(4)} = \frac{56}{40}[/tex]

Now we can put these fractions in order from least to greatest...

[tex]\frac{28}{40} < \frac{55}{40}<\frac{56}{40}[/tex]

Therefore, we know that...

[tex]0.7 < \frac{11}{8} < 1.4[/tex]

Answer:

[tex](f/g)(4)=8[/tex]

Interpretation: 4 elephants traveled at a speed of 8 miles per hour

Step-by-step explanation:

Given

[tex]f(x) = 4x + 8[/tex]

[tex]g(x) = x -1[/tex]

Required

[tex](f/g)(4)[/tex]

This is calculated as:

[tex](f/g)(4)=\frac{f(4)}{g(4)}[/tex]

We have:

[tex]f(x) = 4x + 8[/tex]

[tex]f(4) = 4 * 4 + 8 =24[/tex]

[tex]g(x) = x -1[/tex]

[tex]g(4) = 4 - 1 = 3[/tex]

So:

[tex](f/g)(4)=\frac{f(4)}{g(4)}[/tex]

[tex](f/g)(4)=\frac{24}{3}[/tex]

[tex](f/g)(4)=8[/tex]

Answer:

Answer:C) 8; The elephants’ rate in miles per hour

Step-by-step explanation:

First write the question as an equation that can be solved to give you a numerical answer.

[f(4)=4(4)+8] / [g(4)=(4)-1]

Then solve the equation.

24/3=8

Finally use background information to give you the context.

Since the problem gives you the function for distance and the function for time then it can be concluded that the context will be the elephants’ rate in miles per hour

Answer:

D

Step-by-step explanation:

Given

5 - [tex]\sqrt{c+5}[/tex] = 1 ( subtract 5 from both sides )

- [tex]\sqrt{c+5}[/tex] = - 4 ( multiply both sides by - 1 )

[tex]\sqrt{c+5}[/tex] = 4 ( square both sides )

c + 5 = 4² = 16 ( subtract 5 from both sides )

c = 11

The value of c is 11 when n = 5.To find the value of c in the equation [tex]n - \sqrt(c + 5) = 1[/tex] when n = 5, you can simply substitute n with 5 and then solve for c.

Given equation: [tex]n - \sqrt(c + 5) = 1[/tex]

Now, replace n with 5:

[tex]5 - \sqrt(c + 5) = 1[/tex]

Next, isolate the square root term by moving the constant term to the other side:

[tex]sqrt(c + 5) = 5 - 1\\sqrt(c + 5) = 4\\[/tex]

Now, square both sides of the equation to eliminate the square root:

[tex](c + 5) = 4^2\\c + 5 = 16[/tex]

Finally, isolate c:

c = 16 - 5

c = 11

So, the value of c is 11 when n = 5.
