What is the reference angle for 192°?
A 22°
B. 68°
C. 12°
D. 78°
The required reference angle of angle 192 is 12. OPtion C is correct.
Given that,
An angle of 192°
Reference angle to be determined.
The angle can be defined as the one line inclined over another line.
Angel over angle is of 360° and angle over line is 180°
The function in mathematics to operate and diagnose the function to make the function simple or more coherent is called simplifying and the process is called simplification.
Since in the question, An angle is given of 192° its corresponding and relatable angle is to be determined.
Here, a standard measure of an angle is 180, So let the reference angle b x, for reference angle the angle must be more or less than 180. So,
x = 192 - 180
x = 12
Thus, the required reference angle of angle 192 is 12. Option C is correct.

Sebastian is ordering a taxi from an online taxi service. The taxi charges $3 just for
the pickup and then an additional $0.75 per mile driven. How much would a taxi ride
cost if Sebastian is riding for 10 miles? How much would a taxi ride cost that is m
miles long?
Answer:
10:50
Step-by-step explanation:
Answer:
$10.50 for 10 miles & 0.75m+3 for "m" miles
Step-by-step explanation:
if the taxi charges $3 just for showing up, then in the formula (y=mx+b) 3 would be your "b"
y = mx + 3
if the taxi is charging $0.75 per mile, the mile will be your "x" in the formula, and 0.75 will represent your "m" in the formula
y = 0.75x + 3 - this is your equation for "m" miles
to find how much for 10 miles, substitute 10 for "x" in your formula
y = 0.75 (10) +3
y = 10.50
so it is $10.50 for 10 miles, including the 3 dollar pick up fee.
Celesta used to spend 90 minutes a day on the phone. Now she spends 60 minutes a day. What is the PERCENT DECREASE?
Answer:
-210
Step-by-step explanation:
The percent decrease in the time taken by Celesta is 33.33%.
What is Percentage?Percentage of a number is the parts per 100. Or percentage of a number can be calculated by dividing the number with the whole with respect to which we are finding the percentage of the number and then multiply with 100.
Percentage is a dimensionless number because percentage is not measured by any units.
Percentage decrease can be calculated by the formula,
Percentage Decrease = [(Original value - New value) / Original value] × 100
Time that Celesta used to spend on the phone a day = 90 minutes
Original value = 90
Now, celesta spends 60 minutes a day
New value = 60
Percentage decrease = [(90 - 60) / 90] × 100
= [30 / 90] × 100
= [1 / 3] × 100
= 33.33 %
Hence the percent decrease in the time taken by Celesta in a day is 33.33%.

Step-by-step explanation:
The Science Club wants to print stickers to promote their club and an interest in science. They got a quote to print the stickers from two printers. Pop Art Printing would charge a $25 setup fee and $0.05 per sticker. Sticky Slogans would charge a $12 setup fee and $0.09 per sticker. Write a system of equations that can be used to find the number of stickers for the cost of both printers to be equal.
Answer:
The system of equations =
25 + 0.05x = 12 + 0.09x
The number of stickers where the cost of both printers to be equal is 325 stickers
Step-by-step explanation:
Let the number of stickers = x
Printer 1
Pop Art Printing would charge a $25 setup fee and $0.05 per sticker.
$25 + $0.05× x
25 + 0.05x
Printer 2
Sticky Slogans would charge a $12 setup fee and $0.09 per sticker.
$12 + $0.09 × x
12 + 0.09x
We equate both equations together
The system of equations =
25 + 0.05x = 12 + 0.09x
Collect like terms
25 - 12 = 0.09x - 0.05x
13 = 0.04x
x = 13/0.04
x = 325 stickers
Therefore, the number of stickers where the cost of both printers to be equal is 325 stickers

the height of a hat is shaped like a cone is 10 inches. the volume of thw hat is 30(pi) cubic inches. what is the diameter of the hat?
Answer:
3.38pi
Step-by-step explanation:
Using simple math and the equation for finding the volume of a sphere, we can see that by taking the height of 10, and the volume of 30, that with that information we can deduce that the radius of the cone would be 1.69pi. With this information, we know the radius is half of the diameter. Therefore, we multiply 1.69 by 2, to get our end result, 3.36pi

Step-by-step explanation:
if 1 is a root of the equation
[tex]5x^{2} +kx - 3 = 0 [/tex]
find the other root
Step-by-step explanation:
5x² + kx - 3 = 0 has a root x = 1.
=> 5(1)² + (1)k - 3 = 0
=> 5 + k - 3 = 0
=> k = -2.
Therefore we have 5x² - 2x - 3 = 0.
=> (x - 1)(5x + 3) = 0
=> x = 1 or x = -3/5.
Hence the other root is -3/5.

(2, -4), (x, y) , A , and B all lie on the line. Find an equation relating x and y.
Answer:
An equation relating x and y is:
y = 3/4x - 5.5
Step-by-step explanation:
The slope-intercept form of the line equation
y = mx+b
where
m is the slopeb is the y-interceptGiven the points
(2, -4), (x, y), A(6, -1), and B(10, 2)
Taking any two points let say A(6, -1), and B(10, 2) to determine the slope
[tex]\mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}[/tex]
[tex]\left(x_1,\:y_1\right)=\left(6,\:-1\right),\:\left(x_2,\:y_2\right)=\left(10,\:2\right)[/tex]
[tex]m=\frac{2-\left(-1\right)}{10-6}[/tex]
Refine
[tex]m=\frac{3}{4}[/tex]
We know that the value of the y-intercept can be determined by setting x = 0, and determining the corresponding value of y.
From the graph, it is clear
at x = 0, y = -5.5
Thus, the y-intercept b = -5.5
Thus, substituting b = -5.5 and m = 3/4 in the slope-intercept form of the line equation
y = mx+b
y = 3/4x + (-5.5)
y = 3/4x - 5.5
Therefore, an equation relating x and y is:
y = 3/4x - 5.5

Which logarithmic equation is equivalent to this exponential equation?
2,400 = 7,500(10) *
A.
B.
I = log
log (3)
I = -log ()
I = -log (*)
I = log (1)
OC.
D.
Answer:
B.
Step-by-step explanation:
2,400 = 7,500[tex](10)^{x}[/tex]
First of all, you want to isolate the [tex](10)^{x}[/tex] by dividing each side by 7,500.
After doing this, you will get
[tex]\frac{2400}{7500}[/tex] = [tex](10)^{-x}[/tex].
Putting this in the logarithmic form, you get [tex]log_{10}[/tex] [tex]\frac{2400}{7500}[/tex] = - x
To get rid of the negative sign, you would simply multiply both dies of the equation by -1. So you would get [tex]-log_{10} \frac{2400}{7500}[/tex] = x.
When you simplify 2400/7500, you get 8/25, so the answer is B.
Hope this helps!
You can use the definition of logarithm here.
The logarithmic equation that is equivalent to the given exponential function is given by:
Option C: [tex]x = -\rm log(\dfrac{8}{25})[/tex]
Given logarithmic equation is: [tex]2400 = 7500(10)^{-x}[/tex]To find:The equivalent exponential function to given logarithmic equation.
What is the definition of logarithm?
Logarithm is inverse function to exponentiation.
That means:
[tex]e^a = b \implies a = log_e(b)[/tex]
Transforming given equation to exponential form:[tex]2400 = 7500(10)^{-x}\\\\ \dfrac{2400}{7500} = 10^{-x}\\\\ 10^{-x} = \dfrac{8}{25}\\\\ -x = log_{10}(\dfrac{8}{25})\\\\ x = -log_{10}(\dfrac{8}{25})\\\\[/tex]
Since log with base 10 is simply written log, thus,
The logarithmic equation that is equivalent to the given exponential function is given by:
Option C: [tex]x = -\rm log(\dfrac{8}{25})[/tex]
