In which quadrant is the number –14 – 5i located on the complex plane?
Answer:
3rd Quadrant
Step-by-step explanation:
The "i" in complex numbers behave same as the y in real numbers, so basically this number translated in real would be same as (-14,-5).
To graph this, we have to go -14 units in x direction and -5 units in y direction. Basically, 14 units to the left and then 5 units down. That will place us in 3rd quadrant.
Hence, -14 -5i will fall in the 3rd quadrant of the complex plane.

The grass in jamie's yard grew 16 centimeters in 10 days.It was growing at a constant rate. How many days did it take the the grass to grow 1 centimeter?,How many centimeter did the grass grow in 1 day?
Answer:
1.6 cm
0.625 day
Step-by-step explanation:
We are given that the grass in Jamie's yard grew 16 cm in 10 days.
It was growing at constant rate.
We have to find number of days taken by the grass to grow 1 cm and how many cm grass grow in one day.
In 10 days , grass grow=16 cm
In 1 day, grass grow=[tex]\frac{16}{10}=1.6 cm[/tex]
Grass takes time to grow 16 cm=10 days
Grass takes time to grow 1 cm=[tex]\frac{10}{16}[/tex]=0.625 days
Hence, the grass grow 1 cm in 0.625 days and the grass grow 1.6 cm in one day.
To find the number of days it took for the grass to grow 1 centimeter, divide the number of days by cm of growth. This equals 0.625 days. To find how many centimeters the grass grew in a day, divide the total growth by the total number of days. This equals 1.6 centimeters per day.
Explanation:The problem states that the grass in Jamie's yard grew 16 centimeters in 10 days at a constant rate. We can set up two equal ratios to find out how many days it took for the grass to grow 1 centimeter and how many centimeters it grew in 1 day.
Firstly, to determine the number of days it took for the grass to grow 1 centimeter, you can divide the number of days (10) by the number of centimeters (16). This gives us 10/16 = 0.625 days for the grass to grow 1 centimeter. Secondly, to determine how many centimeters the grass grew in 1 day, you would divide the total growth (16 centimeters) by the total number of days (10). This results in 16/10 = 1.6 centimeters of growth per day. Learn more about Ratio and Proportion here:

in a cirlce of radius 5 cm, what is the length in cm of an arc subtended by a central angle measuring 2 radians?
Answer:
The length L is 10 cm
Step-by-step explanation:
We need to find the length of the arc subtended by a central angle of 2 radians and the circle has radius of 5cm.
So, the formula used will be:
l = r Θ
Where L= length of arc
r= radius of circle
and Θ is angle
In The given question
L=?
r = 5 cm
Θ = 2 radians
Putting values in formula:
L = r Θ
L = 5 * 2
L = 10 cm
So, the length L is 10 cm
Final answer:
The length of the arc subtended by a central angle of 2 radians in a circle of radius 5 cm is 5 cm.
Explanation:
The length of an arc subtended by a central angle can be found using the formula:
Length of arc = (central angle / 2π) × circumference of the circle
In this case, the central angle is 2 radians and the radius of the circle is 5 cm. The circumference of the circle is given by 2πr, where r is the radius. So, the length of the arc can be calculated as:
Length of arc = (2 / 2π) × (2π × 5) = 5 cm

a bottle contains 2.360 ml of a liquid. the total mass of the bottle and liquid together is 6.160g. The mass of the empty bottle is 4.850 g. what is the density of the liquid?
A) 2.610 ml
B) 1.802 ml
C) 0.555 ml
D) 2.055 ml
Answer:
C.) 0.555
Step-by-step explanation:
This is annoying because we're dealing with decimals.
So, we need to know how density works. Density works by dividing mass (g) by volume (ml).
Since the empty bottle has a mass of 4,850g and the bottle + the liquid have a total mass of 6.160g, we'll subtract the bottle's mass from the total mass, giving us 1.310g. Again, we divide mass by volume to obtain density (which should be listed as g/ml).
1.310 ÷ 2.360 = ~0.555
Therefore, your answer is 0.555
The density of the liquid in the bottle is calculated by dividing the mass of the liquid (found by subtracting the mass of the empty bottle from the total mass when full) by its volume. The correct answer is C) 0.555 ml.
Explanation:The subject here is density, which is a physical property of a substance that can be calculated by its mass over its volume. In your case, you are being asked to find the density of the liquid inside the bottle. This can be done by first, finding the mass of the liquid alone, then dividing that by the volume of the liquid given in the question.
The mass of the liquid can be found by subtracting the mass of the empty bottle from the total mass of the bottle when full (6.160g - 4.850g = 1.310g). The volume of the liquid is already given as 2.360 ml.
Finally, you compute the density by dividing the mass of the liquid by its volume (1.310g / 2.360 ml = 0.555 g/ml).
So, the correct choice is C) 0.555 ml.

Step-by-step explanation:
cos 330°=cos ( 360 -30)
In fourth quad the value of cos A is positive .
All angles when subtracted by multiple of 180° or (π) the function remain same
cos (30°)=√3/2
Also-
Cos(330)=Cos(360–30)
since Cos(360-x)=cos(x) where x is in degree
Cos(330)=Cos(30)= √ 3 /2 ~ 0.866
Answer:
Answer:
cos ( 330 º ) = √ 3 /2
Explanation:
Remember that
cos ( a − b ) = cos ( a ) cos ( b ) + sin ( a ) sin ( b )
and that
330 º = 360 º − 30 º , so
cos ( 330 º ) = cos ( 360 º − 30 º ) = cos ( 360 º ) cos ( 30 º ) + sin ( 360 º ) sin ( 30 º )
The cosine, sine, tangent and secant of 360º equal the cosine, sine, tangent and secant of 0º respectively. We know that
sin 0 º is 0, and that cos 0 º = 1 so
cos ( 330 º ) = 1 ⋅ cos ( 30 º ) + 0 ⋅ sin ( 30 º )
cos ( 330 º ) = √ 3 /2

we have that
Describe
A) slope of the line
B) equation of the line
C) y-intercept
D) slope of a line perpendicular to the given line
Part A) slope of the line
we know that
The formula to calculate the slope between two points is equal to
[tex]m=\frac{y2-y1}{x2-x1}[/tex]
we have
[tex](p,a)\ (p,-a)[/tex]
Substitute the values
[tex]m=\frac{-a-a}{p-p}[/tex]
[tex]m=\frac{-2a}{0}[/tex] -----> the slope is undefined

Part B) Equation of the line
we know that
The equation of a vertical line is equal to the x-coordinate of the points through which the line passes.
so
[tex]x=p[/tex]
Part C) The y-intercept
The y-intercept is the value of y when the value of x is equal to zero
The vertical line not intercept the y-axis
so
None y-intercept
Part D) slope of a line perpendicular to the given line
A line perpendicular to the given line is a horizontal line (parallel to the x-axis)
therefore
The slope is equal to zero
Which set of ordered pairs is a function?
Answer:
The second set is a function as none of the x values repeat.
Step-by-step explanation:
In order for a set of ordered pairs to be a function, they must only have one range value for each domain value.
In other words, an x value cannot occur twice.
Within the first set, the value x=2 is repeated 5 times. This means that it is not a function
Within the third set, the value x=1 is repeated twice and x=4 is repeated twice, This means that it is not a function
Within the fourth set, the value x=1 is repeated twice and x=2 is repeated twice, this means that this is not a function
The second set is a function as none of the x values repeat.

Which is a counterexample for the conditional statement shown?
If two distinct points are graphed on a coordinate plane, then the line connecting the points can be represented with a function.
The points have the same x-coordinate value.
The points have the same y-coordinate value.
The points follow the rule (x, y) (–x, –y).
The points follow the rule (x, y) (–y, –x).
Answer: First Option
The points have the same x-coordinate value.
Step-by-step explanation:
By definition, a relation is considered a function if and only if for each input value x there exists only one output value y.
So, the only way that the line that connects two points in the coordinate plane is not a function, is that these two points have the same coordinate for x.
For example, suppose you have the points (2, 5) and (2, 8) and draw a line that connects these two points.
The line will be parallel to the y axis.
Note that the value of x is the same x = 2. But when x = 2 then y = 5 and y = 8.
There are two output values (y = 8, y = 5) for the same input value x = 2.
In fact all the vertical lines parallel to the y-axis have infinite output values "y" for a single input value x. Therefore, they can not be defined as a function.
Then the correct option is:
The points have the same x-coordinate value.
50 points!

it take for the frog to get out of the well?
B. What if the well was 40 feet deep, the frog climbs 6 feet per hour, and it slips back

Answer:
A: 5 hrs. B: 14 hrs. and 40 min.
Step-by-step explanation:
too long to explain.
In the first scenario, the frog takes 4 hours to get out of the 8-feet deep well. In the second scenario, it takes the frog 8 hours to get out of the 40-feet deep well.
Explanation:The question is about calculated frog’s movement to get out of a well involving both climbing rate and slip-back rate during rest which brings us into the realm of simple arithmetic and mental math. Let's take each case one at a time.
A. 8 Feet Deep Well
The frog climbs 4 feet per hour but then slips back 2 feet. Therefore, effectively, the frog climbs only 2 feet per hour (4-2=2). After 3 hours, the frog would have climbed 6 feet (3*2=6). In the fourth hour, the frog would climb another 4 feet reaching a total of 10 feet, but since the well is only 8 feet deep, he would have already climbed out. Therefore, it would take the frog 4 hours to climb out of the well.
B. 40 Feet Deep Well
The frog climbs 6 feet per hour and slips back 1 foot, therefore effectively climbs 5 feet per hour (6-1=5). After 7 hours, the frog would have climbed 35 feet (7*5=35). In the eighth hour, the frog would climb additional 6 feet, reaching a total of 41 feet. Again, considering the well is only 40 feet deep, he would have climbed out at this point. So, it would take 8 hours for the frog to climb out of a 40 feet deep well.

Which two points in the graphed function have an average rate of change of 5?
Answer:
B. points A and B
Step-by-step explanation:
"Rate of change" is just a fancy name for slope.
The question asks for points on the graph having a slope of 5. We know a slope of 5 is a positive (goes up from left to right) and it's quite steep.
By looking at the graph, we see that to have a slope of 5, it has to take place in the first half of the graph.
Let's look at the possible options:
A. Points D and F: From point D to point F, you're going down, so the slope is negative. NO
B. Points A and B: goes up, pretty steep. Let's calculate the slope.
Point A: (2,1), Point B: (3,6)
Slope = (6 - 1) / (3 - 2) = 5 / 1 = 5
We found it!
C. Points B and C: goes up, pretty steep too. Let's calculate the slope:
Point B: (3,6) , Point C: (4,9)
Slope = (9 - 6) / (4 - 3) = 3 / 1 = 3, NO, not the slope we're looking for
D. Points C and E: goes down, NO, not what we want.
The figure shows a blueprint of a dining room, kitchen, and living room. Each square has a side length of 1/4 inch. Tile costs $7 per square foot. What is the cost of the tile for the kitchen?
The cost of the tile for the kitchen is $___
Answer:
The cost of the tile for the kitchen is $1,680
Step-by-step explanation:
step 1
we know that
The scale drawing is [tex]\frac{1}{16}\frac{in}{ft}[/tex]
The dimensions of the kitchen in the blueprint are
L=3(1/4)=3/4 in
W=5(1/4)=5/4 in
step 2
Find the actual dimensions of the kitchen
Divide the dimensions of the kitchen in the blueprint by the scale drawing
L=(3/4)/(1/16)=12 ft
W=(5/4)/(1/16)=20 ft
The area is equal to
A=(12)(20)=240 ft²
step 3
Find the cost of the tile for the kitchen
7(240)=$1,680
Answer:
Cost of the tiles for the kitchen is $1680
Step-by-step explanation:
From the figure attached,
Dimensions of the kitchen = 5 small squares by 3 small squares
Since 1 small square = [tex]\frac{1}{4}[/tex] inch
So the dimensions of the kitchen in inches = [tex]\frac{5}{4}[/tex] inches by [tex]\frac{3}{4}[/tex] inches
Map Scale has been given as
1 inch = 16 ft
Therefore actual dimensions of the kitchen will be
[tex]\frac{5}{4}\times 16[/tex] ft by [tex]\frac{3}{4}\times 16[/tex] ft
= 20 ft by 12 ft
Area of the kitchen = 20×12
= 240 ft²
Per square feet tile cost = $7
So the cost of tiling 240 ft² will be = 240 × 7
= $1680
Therefore, cost of the tiles for the kitchen is $1680

u What is the volume of the cone to the nearest whole number?
Answer:
V=167.5 cubic mm
Step-by-step explanation:
Volume of the Cone is given with the formula
[tex]V=\frac{1}{3} \pi r^2h[/tex]
though we are not specified what is radius and which one is the height , we are assuming that ,
Height = 10 mm
Radius = 4 mm
Substituting these values in the formula we get
[tex]V=\frac{1}{3} \pi 4^2 \times 10[/tex]
[tex]V=\frac{1}{3} \pi 160[/tex]
[tex]V=\frac{160 \times 3.14}{3}[/tex]
[tex]V=\frac{160 \times 3.14}{3}[/tex]
[tex]V=\frac{502.40}{3}[/tex]
[tex]V=167.5[/tex]
what is the surface area of this square pyramid
Answer:
33 ft²Step-by-step explanation:
We have
the square with side s = 3ft
four triangles with base b = 3ft and height h = 4ft
The formula of an area of a square:
[tex]A=s^2[/tex]
The formula of an area of a triangle:
[tex]A=\dfrac{bh}{2}[/tex]
Substitute:
[tex]A_{\square}=3^2=9\ ft^2[/tex]
[tex]A_{\triangle}=\dfrac{(3)(4)}{2}=\dfrac{12}{2}=6\ ft^2[/tex]
The Surface Area:
[tex]S.A.=A_{\square}+4A_{\triangle}\\\\S.A.=9+(4)(6)=9+24=33\ ft^2[/tex]
Answer:
33 ft&²
Step-by-step explanation:
multiply 4x3x3 = 36 and put half of 6, then it is 33 33ft²
