Answer:
81cm^2
Step-by-step explanation:
Answer:
81
Step-by-step explanation:
Let's do a quick refresher on how to find area.
l = length
w = width
a = area
a = l(w)
Since one side is 9cm, and all the sides are equal, you multiply 9x9.
Nine times nine is 81.

Find the directional derivative of the function f(x,y)=2cos(y)exf(x,y)=2cos(y)ex at the point (0,π6)(0,π6) in the direction of the vector v=⟨−8,6⟩v=⟨−8,6⟩.
Answer:
[tex]D_u f(0,\pi/6)=\frac{4\sqrt{3}-3}{5}[/tex]
Step-by-step explanation:
We are given that
[tex]f(x,y)=2cos(y)e^{x}[/tex]
Point=([tex]0,\pi/6[/tex])
Vector v=<-8,6>
We have to find the directional derivative of the function.
[tex]f_x(x,y)=2cos(y)e^{x}[/tex]
[tex]f_x(0,\pi/6)=\sqrt{3}[/tex]
[tex]f_y(x,y)=-2sin(y)e^{x}[/tex]
[tex]f_y(0,\pi/6)=-1[/tex]
[tex]|v|=\sqrt{(-8)^2+6^2}=\sqrt{100}=10[/tex]
[tex]\hat{u}=\frac{v}{|v|}=\frac{-8i+6j}{10}=\frac{1}{10}(-8i+6j)[/tex]
[tex]\nabla f(0,\pi/6)=<f_x(0,\pi/6),f_y(0,\pi/6)>=<\sqrt{3},-1>[/tex]
Now, the directional derivative in the direction of v at point (0,[tex]\pi/6[/tex]) is given by
[tex]D_u f(0,\pi/6)=\nabla f(0,\pi/6)\cdot \hat{u}[/tex]
By using the formula
[tex]D_u f(x,y)=\nabla f(x,y)\cdot \hat{u}[/tex]
[tex]D_u f(0,\pi/6)=<\sqrt{3},-1>\cdot <-\frac{8}{10},\frac{6}{10}>[/tex]
[tex]D_u f(0,\pi/6)=-\frac{4\sqrt{3}}{5}-\frac{3}{5}=-\frac{1}{5}(4\sqrt{3}+3)[/tex]
which number is ten times more than 0.006
Answer:
0.06
Step-by-step explanation:
0.006 x 10
When multiplying by 10, 100, 1000, 10000, etc, you move the decimal place to the right as many times as there are zeros in what you are multiplying it by. Because there is one zero in ten, we move the decimal place one to the right.
0.06

Find the area of the figure shown below and choose the appropriate result.
4 cm
2 cm
5 cm
6 cm
A 34 cm2
B 44 cm
54 cm
D 46 cm
Answer:
the answer is D 46 cm
Step-by-step explanation:
first you need to find the missing side measurements cutting in two separate figures. if one side is 2 you know the other side is also 2 same with the 4 if the top is 4 the bottom is 4 too so now you have the measurements for the first figure now you finder the area applying the formula
A=bxh
A= 4*2=8
second figure you know that one part of the rectangle top is 5 and if you add the 4 of the first figure give you the measurement of the top
5+4=9 so if the top is 9 the bottom is also 9
finally to find the other side you know the side is 6 and since you know one part of the first figure is 2 you need to subtract 6-2=4
A=bxh
A=9*4=28
once you have both you can add it 28+8=46

A pound has 60 German Shepherds and 40 Great Danes of both sexes. If they breed with each other randomly, what is the probability that the puppies are: (i) pure breed German Shepherds, (ii) pure breed Great Danes, (iii) German Shepherd-Great Danes
Answer:
(i) pure breed German Shepherds,= 0.6
(ii) pure breed Great Danes,= 0.4
(iii) German Shepherd-Great Danes= 0.24
Step-by-step explanation:
The probability of success for the German shepherd is 60/100 0r 6/10 0r 0.6
The probability of failure for the German shepherd is 40/100 0r 4/10 0r 0.4
The probability of success for the Great Danes is 40/100 0r 4/10 0r 0.4
The probability of failure for the Great Danes is 60/100 0r 6/10 0r 0.6
The probability that it is a pure German shepherd is 60/100 0r 6/10 0r 0.6
The probability that it is a pure the Great Danes is 40/100 0r 4/10 0r 0.4
The probability that the puppies are: German Shepherd-Great Danes is given by since the events are independent
P (GS ∩ GD) = 0.6* 0.4= 0.24

Study the Venn diagram.
A Venn diagram. A large box is labeled rational numbers. A box inside the rational numbers box is labeled integers. A box inside the integers box is labeled whole numbers.
Which statement is correct?
–5 cannot be written as a fraction, so it is not rational.
–5 is a rational number, but not an integer.
–5 is a counting number, so it is also a whole number.
–5 is an integer, but not a whole number.
5 is an integer, but not a whole number.
A Venn diagram is a widely sued diagram and shows a logical relationships within the sets.
As per the Venn diagram the large box is labeled by a rational number. The numbers are integers and the box and them are labeled by the while numbers. Hence 5 number is an integer, but not the whole number. Thus option D is correct.Learn more about the Study the Venn diagram.

The waiting times between a subway departure schedule and the arrival of a passenger are uniformly distributed between 0 and 5 minutes. Find the probability that a randomly selected passenger has a waiting time greater than 2.25 minutes.
Answer: 0.75
Step-by-step explanation:
Given : Interval for uniform distribution : [0 minute, 5 minutes]
The probability density function will be :-
f(x) = 1/5-0 = 1/5 = 0.2, 0<x<5
The probability that a given class period runs between 50.75 and 51.25 minutes is given by :-
Hence, the probability that a randomly selected passenger has a waiting time greater than 1.25 minutes = 0.75

A. Solve the equation 0.8x = 1.
B. Solve the equation 0.8 + x = 1.
C. Divide 1 by 0.8.
Answer:
C
Step-by-step explanation:
Because in the end, 0.8 is decimal that can be converted to a fraction which can then be flipped. 4/5 = 0.8. So the reciprocal would be 5/4 or 1.25.
1 / 0.8 = 1.25

Answer: the answer is choice b
Step-by-step explanation:
The data in the first table represents a linear function that has a slope of zero
Linear equation
A linear equation is in the form:
y = mx + b
where y, x are variables, m is the slope of the line and b is the y intercept.
Slope (m) = change in y / change in x
From the first table, using the point (-5, 5) and (-1, 5), hence:
Slope = (5 - 5)/(-1 - (-5)) = 0
The data in the first table represents a linear function that has a slope of zero

Which number line can be used to find the distance between (-1,2) and (-5,2)
Answer:
The number line is y = 2.
Step-by-step explanation:
We are given the points (-1,2) , (-5,2) and we have to find the number line that can be used find the distance between them.
The y coordinate of the two points is
same (equal to 2) , so the number line that can be used to find the distance between them is y = 2.
Distance between the points = |-5+1| = 4
f (x) = 5x - 1, find f (4) - show work
Answer:
f(4) = 19
Step-by-step explanation:
Plug in 4 for x in the given equation:
f(x) = 5x - 1
f(4) = 5(4) - 1
Simplify. Remember to follow the order of operations, PEMDAS. First multiply, then subtract:
f(4) = (5 * 4) - 1
f(4) = 20 - 1
f(4) = 19
f(4) = 19 is your answer.

One number is selected from the set {1, 2, 3, 4, 5, 6, 7, 8, 9}. Find the probability the selected number is less than 7, given that it is less than 8.
Give your answer as a decimal rounded to 4 decimal places.
====================================================
Explanation:
We're told that "given that it is less than 8", so we only focus on these values {1,2,3,4,5,6,7}. There are B = 7 items in this set.
Of those, the set {1,2,3,4,5,6} are less than 7. There are A = 6 items in this set.
The probability we're after is A/B = 6/7 = 0.8571
Answer:
I just got this question in my book, and i already solved it. so just saying that i now the answer, it is 0.8571
