Sharon paid $78 sales tax on a new camera. If the sales tax is 6.5%, what was the cost of the camera?
Answer:
$1200
Step-by-step explanation:
$1200
Step-by-step explanation:
78 = 6.5%
This means that if you divide 78 by 6.5, you get the equivalent of 1% of the price:
78 ÷ 6.5 = 12
So 1% = 12
Now simply multiply this by 100 to get the full answer:
12 x 100 = 1200
So the camera cost $1200!
Answer:
$1,200
Step-by-step explanation:
78 divided by 6.5=12
With percents you have to multiply to get out of 100 so:
12x100=1,200
78 divided by 6.5%=1,200

Answer:
(1/120 mile/min)(60 min/h)(3 h)
1.5 mile
the increase in depth after 3 hours
Step-by-step explanation:
The rate is given in terms of miles per minute. To find the elevation after 3 hours, we need a conversion from minutes to hours. One possible product is ...
(1/120 mile/min)(60 min/h)(3 h)
The value of this product is ...
(1·60·3)/(120·1·1) mile = 1.5 mile
The value represents the increase in depth after 3 hours.

Which function is a quadratic function?
f(x) = 2x2
g(x) = 5x3
k(x) = –x
b(x) = –9x4
Answer:
The simplest parabola is y = x2, whose graph is shown at the right. The graph passes through the origin (0,0), and is contained in Quadrants I and II. This graph is known as the "Parent Function" for parabolas, or quadratic functions.
So the answer is f(x) = 2x2
Thank you and please rate me as brainliest as it will help me
The function f(x) = 2x² is the quadratic function while the other functions are not the quadratic function. The first option is the correct one.
A quadratic function is a polynomial with degree 4.
f(x) = 2x² is a quadratic function as the degree of the function is 2.
g(x) = 5x³ is a cubic function as the degree of the function is 3.
k(x) = -x is a linear function as the degree of the function is 1.
[tex]b(x) = -9x^4[/tex] is a quartic function as the degree of the function is 4.
So, among all options, f(x) = 2x² is the quadratic function. The correct option is the first one.

Step-by-step explanation:
A train travels 16.8 km in 25 mins. find the speed of the train in
(i)km/h (ii) m/s.
i. Distance = 16.8 km
Time = 25 mins = 5/12hours
Speed = distance/time
= 16.8÷(5/12)
= 16.8 × 12/5
= 40.32 km/h
ii. In m/s = 40.32/3.6
= 11.2 m/s
The speed of the train is 11.2 m/s.
The speed of the train is 40.32 km/h.
What is speed?Speed is the ratio of distance and time.
It shows how fast an object is moving at a given time.
We have,
Distance.
= 16.8 km
= 16.8 x 1000
= 16800 m
Time.
= 25 minutes
= 25 x 60 seconds
= 1500 seconds
Speed.
= Distance / Time
= 16800 / 1500
= 16800 / 1500
= 11.2 m per second
Speed.
Distance = 16.8 km
Time = 25/60 hours
Speed = (16.8 x 60) / 25 = 40.32 km per hour.
Thus,
The speed is 40.32 km per hour.
The speed is 11.2 meters per second.

Find the instantaneous rate of change of the function f(x)=3x^2 as x approaches 3.
Answer:
The instantaneous rate of change as x approaches 3 is 18.
Step-by-step explanation:
From Differential Calculus and Geometry we remember that instantaneous rate of change of the function is represented by a tangent line, whose slope is determined by the first derivative of the curve. Let [tex]f(x) = 3\cdot x^{2}[/tex], the instantaneous rate of change of the function when x approaches 3 is deducted from the definition of derivative:
[tex]f'(x) = \lim_{h \to 0} \frac{f(x+h)-f(x)}{h}[/tex] (1)
[tex]f'(x) = \lim_{h\to 0} \frac{3\cdot (x+h)^{2}-3\cdot x^{2}}{h}[/tex]
[tex]f'(x) = \lim_{h\to 0} \frac{3\cdot (x^{2}+2\cdot x\cdot h +h^{2})-3\cdot x^{2}}{h}[/tex]
[tex]f'(x) = \lim_{h\to 0} \frac{3\cdot x^{2}+6\cdot x\cdot h+3\cdot h^{2}-3\cdot x^{2}}{h}[/tex]
[tex]f'(x) = \lim_{h\to 0} \frac{6\cdot x\cdot h +3\cdot h^{2}}{h}[/tex]
[tex]f'(x) = \lim _{h\to 0} (6\cdot x+3\cdot h)[/tex]
[tex]f'(x) = 6\cdot x \cdot \lim_{h\to 0} 1 + 3\cdot \lim_{h\to 0} h[/tex]
[tex]f'(x) = 6\cdot x[/tex] (2)
If we know that [tex]x = 3[/tex], then the instantaneous rate of change as x approaches 3 is:
[tex]f'(3) = 6\cdot (3)[/tex]
[tex]f'(3) = 18[/tex]
The instantaneous rate of change as x approaches 3 is 18.
The following are the ages (years) of 5 people in a room: 22, 13, 17, 15, 17 A person enters the room. The mean age of the 6 people is now 17. What is the age of the person who entered the room?
Answer:
the 6th man's age is 58!
Step-by-step explanation:
First you have to find the mean of 22, 13, 17, 16, and 17, by first adding 22, 13, 17, 16, and 17 to get 85. Because mean is the numbers added up divided by the total amount of numbers, there are 5 numbers and then you have to divided 85 by 5.
After you get the mean of these numbers, find the other number which will level the mean to 17.

How do you do this question?
Step-by-step explanation:
f(x) = sin(x), a = π/6, n = 4
Find the derivatives.
f⁽⁰⁾(π/6) = sin(π/6) = ½
f⁽¹⁾(π/6) = cos(π/6) = ½√3
f⁽²⁾(π/6) = -sin(π/6) = -½
f⁽³⁾(π/6) = -cos(π/6) = -½√3
f⁽⁴⁾(π/6) = sin(π/6) = ½
T₄(x) = ½ (x − π/6)⁰ / 0! + ½√3 (x − π/6)¹ / 1! − ½ (x − π/6)² / 2! − ½√3 (x − π/6)³ / 3! + ½ (x − π/6)⁴ / 4!
T₄(x) = ½ + ½√3 (x − π/6) − ¼ (x − π/6)² − ¹/₁₂√3 (x − π/6)³ + ¹/₄₈ (x − π/6)⁴
Find the fifth derivative.
f⁽⁵⁾(x) = cos(x)
So the next term of the series would be:
cos(z) (x − π/6)⁵ / 5!
For 0 ≤ z ≤ π/3,│f⁽⁵⁾(x)│is a maximum at z = 0. Therefore:
│R₄(x)│≤ │cos(0) (0 − π/6)⁵ / 5!│
│R₄(x)│≤ 0.000328
│R₄(x)│is always positive, so we can ignore the bottom two graphs. The top right graph has a y-intercept of approximately 0.0003, so that is the correct graph.
