if f(x)=2^x and g(x)=x-4. The graph of (fog)(x) is shown below. What is the range of (fog)(x)?
Answer:
C) [tex]y > 0[/tex]
Step-by-step explanation:
[tex]f(x)=2^x\\\\g(x)=x-4\\\\(f\circ g)(x)=f(g(x))=f(x-4)=2^{x-4}[/tex]
This means that the parent function, [tex]f(x)=2^x[/tex], will shift 4 units to the right along the x-axis, so this DOES NOT affect the range (nor the domain either). Thus, [tex]y > 0[/tex] would be the range.

Artichokes were on sale. Five of them cost $1. At this rate, what would be the price for a dozen artichokes?
Group of answer choices
$2.52
$2.50
$2.40
Answer:
$2.40
Step-by-step explanation:
as five of artichokes caused $1, a dozen is the same number as 12, so use cross multiply and you will get the answer $2.40
cross multiply : 5 artichokes = $1
12 artichokes = x
5x = $1 x $12
5x = $12
x = 12/5
x = $2.40

Priya is mixing drops of food coloring to create purple frosting for a cake she uses 24 drops of red dye and 16 drops of blue dye find the ratio of drops of red dye to total drops of dye
Answer:
24:40
Step-by-step explanation:
To find the radio for red dye to total drops of dye, just add the red and blue dye.
The ratio of drops of red dye to total drops of dye is 3:2.
What is Ratio?When a number is divisible by another number, then it can be written in the form of a:b, this is called Ratio.
Priya is making frosting.
The number of drops of blue dye is 16.
The number of drops of red dye is 24.
Ratio ( Red dye : Blue dye) = 24 : 16
Ratio ( Red dye : Blue dye) = 3:2

With a coupon you can get a pair os shoes that normally costs $84 for only $72 what percentage was the discount
Given parameters:
Original selling price = $84
Discounted Selling price = $72
Unknown:
Percentage discount = ?
Solution:
To find the percentage discount;
Find the discount amount Then find the percentage discount from this value when you place it over the original selling priceDiscount = Original selling price - Discounted selling price
= $84 - $72
= $12
Now,
Percentage discount = [tex]\frac{12}{84} x 100[/tex] = 14.3%

I know that
[tex] \cot {}^{2} (x) + 1 = \csc {}^{2} (x) [/tex]
So These the steps I need to do:
First Apply Reciprocal Identies to find Cot x.
[tex] \frac{1}{ \tan(x) } = \cot(x) [/tex]
So cot x is
[tex] \frac{24}{7} [/tex]
Now, I can squared that result and add 1 to get csc^2(x).
[tex] \frac{576}{49} + 1 = \frac{576}{49} + \frac{49}{49} = \frac{625}{49} [/tex]
Now, I take the principal square root since csc is positve when theta is in the 1st quadrant.
[tex] \frac{ \sqrt{625} }{ \sqrt{49} } = \frac{25}{7} [/tex]
So
[tex] \csc(x) = \frac{25}{7} [/tex]
[tex]cosec{\theta=\frac{25}{7}is\ the\ answer.}[/tex]
Step-by-step explanation:[tex]If\ tan\ \theta=\frac{7}{24},0\ degrees < \theta < 90\ degrees[/tex]
[tex]sec\ \theta=\sqrt{1+\tan^2\theta}=\sqrt{1+\frac{49}{576}}=\sqrt{\frac{625}{576}}=\frac{25}{24}[/tex]
[tex]cos\ \theta=\frac{1}{sec\ \theta}=\frac{24}{25}[/tex]
[tex]sin\ \theta=\sqrt{1-\cos^2\theta}=\sqrt{1-(\frac{24}{25})^2}=\sqrt{\frac{49}{625}}=\frac{7}{25}[/tex]
[tex]cosec\ \theta=\frac{1}{sin\ \theta}=\frac{25}{7}[/tex]
[tex]Hence,\ cosec\ \theta=\frac{25}{7}is\ the\ answer.[/tex]

A pharmacist has 50 g of a topical cream that contains 75% glycerine. How many grams of the cream are not glycerine?
Answer:
12.5 g
Step-by-step explanation:
75% with glycerine, so 100% - 75% = 25% without glycerine
so 50 g ^ 25% = 12.5 g without glycerine

What is x in this figure?
Answer: x=36
Assuming that O is the centre of the circle,
108+a+a=180(sum of the interior angles of a triangle is 180)
2a=180-108
2a=72
a=72÷2
a=36
a=x (angles in the same segment are equal)
Therefore x=36

Answer: 10
Step-by-step explanation:
Since -2 is in between -5 and 0, we will use the part of the function that says f(x)=x^2 + 3x.
Substituting x=-2, we get (-2)^2 -3(-2)=4+6=10

For what values of a are the following expressions true?
1. |a-5|=5-a
2.|a|=-a
Answer:
1. a = 0 and 5
2. no solutions
Step-by-step explanation:
For absolute value, it's the distance from that number on the number line to 0, so it has to be positive. We define absolute value as when |a| = b, a = b and a = -b.
1. |a - 5| = 5 - a
a - 5 = 5 - a
2a = 10
a = 5
AND
a - 5 = -(5 - a)
a - 5 = -5 + a
-5 = -5
a = 0 (a could work as 0 in this scenario)
Thus our solutions are a = 0 and 5.
2. |a| = -1
Now we have to catch ourselves here. Since absolute value is always positive, nothing works. There is no negative distance to 0 (at least in real numbers). Hence, we can say that there are no solutions.

Question 2.2 write down the general formula for the nth term of sequence. Mystic Rose
Answer:
The nth term of an arithmetic sequence is given by. an = a + (n – 1)
Answer:
The nth term of an arithmetic sequence is given by an = a + (n – 1)d. So, to find the nth term, substitute the given values a = 2 and d = 3 into the formula.

if h(x) = x^2-5x+7 find each value
1/3*h(-8)
if h(x) = [tex]x^{2} -5x+7[/tex] so the value of [tex]\frac{1}{3}[/tex]× [tex]h(-8)[/tex] = [tex]\frac{111}{3}[/tex].
A mathematical equation is a formula that uses the equals sign to represent the equality of two expressions. The meanings of the word equation and its cognates in other languages can vary slightly. For instance, in French, an equation is defined as having one or more variables, whereas, in English, an equation is any well-formed formula that consists of two expressions linked by the equals sign.
Finding the values of the variables that result in equality is the first step in solving an equation with variables. The variables that must be included in the equation are also known as the unknown.
we have h(x) = [tex]x^{2} -5x+7[/tex]
So, substitute the value [tex]x=-8[/tex] in the equation,
h([tex]-8[/tex]) = [tex](-8)^{2} -5(-8)+7[/tex]
= [tex]64+40+7[/tex]
= [tex]111[/tex]
And now we shall multiply it with [tex]\frac{1}{3}[/tex],
we get, [tex]\frac{1}{3}[/tex]× [tex]h(-8)[/tex] = [tex]\frac{111}{3}[/tex]

Find the mean for the set of data.
0.2, 0.21, 0.17, 3.22, 0.2
Answer:
0.8
Step-by-step explanation:
Find the mean of the list:
(0.2, 0.21, 0.17, 3.22, 0.2)
The mean of a list of numbers is given by:
(sum of elements)/(number of elements)
(sum of elements) = 0.2 + 0.21 + 0.17 + 3.22 + 0.2:
(0.2 + 0.21 + 0.17 + 3.22 + 0.2)/(number of elements)
Counting, we see that the list has 5 elements:
(0.2 + 0.21 + 0.17 + 3.22 + 0.2)/5
0.2 + 0.21 + 0.17 + 3.22 + 0.2 = 4:
4/5
4/5 = 0.8:
Answer: 0.8
Answer:
0.8
Step-by-step explanation:
The mean of the data set can be found by adding all terms together and dividing by the amount of terms there is. In this case, add all the numbers and divide by 5:
(0.2 + 0.21 + 0.17 + 3.22 + 0.2)/5 =
(4)/5 = 0.8
0.8 is the mean for the given set.
