a rectangular field is 50 M long and 30 M broad . find a perimeter b) the length of wire required to fence it thrice c)calculate area of a rectangular field
Answer: b) 160 c) 1500
Step-by-step explanation: b) 50 + 50 + 30 + 30 = 160 c) 50 x 30 = 1500
Step-by-step explanation:
[tex]length \: of \: a \: field \: = 50m[/tex]
[tex]breadth \: of \: a \: field \: = 30m[/tex]
[tex]Perimeter \: of \: a \: field \: = ? [/tex]
We know,
Perimeter ( p ) = 2 ( l + b )
= 2 ( 50m + 30m )
= 2 × 80 m
= 160 m
The length of a wire required to fence it thrice
= 3 × 160 m
= 480 m
Area ( A ) = l × b
= 50 × 30 m
[tex] = {1500m}^{2} [/tex]
Write the point-slope form of a line that has slope −7 and passes through the point (4, 8)
Answer:
y = -7x + 36
Step-by-step explanation:
Point-slope form: y - y1 = m(x - x1)
y1 = y-value of a point on a linem = slopex1 = x-value of a point on a lineSubstitue 8 for y1, and 4 for x1, and -7 for m:
y - y1 = m(x - x1)
y - 8 = -7(x - 4)
Solve:
y - 8 = -7(x - 4) <== distribute -7
y - 8 = -7x + 28 <== add 8 to both sides
+ 8 + 8
y = -7x + 36
Therefore, the point-slope of the line is y = -7x + 36
Check your answer using (4, 8):
y = -7x + 36
8 = -7(4) + 36
8 = -28 + 36
8 = 8
This statement is correct
Hope this helps!

If $4204 is invested at 4% per year simple interest for 7 years, at what simple interest rate r would it need to be
invested for 5 years to earn the same amount of interest? Express r as a percentage correct to 2 decimal places.
The answer to this question is in the picture which is 0.56% to 2dp
Answer:
5.60%
Step-by-step explanation:
We can use the formula for simple interest to solve this problem. The formula is:
[tex]\boxed{\bold{SI =\frac{ P * T* R}{100}}}[/tex]
Where:
SI is the simple interest earnedP is the principal amount investedR is the interest rateT is the time period in yearsIf $4204 is invested at 4% per year simple interest for 7 years, the interest earned will be:
[tex]SI = \frac{4204 *4* 7}{100} = 1177.12[/tex]
In order to earn the same amount of interest of $1177.12, the investment of $4204 must be invested for 5 years at a simple interest rate of:
[tex]1177.12=\frac{4204*5*r}{100}[/tex]
Doing Criss cross multiplication
[tex]r=\frac{1177.12*100}{4204*5}[/tex]
r=5.60 %
To two decimal places, the interest rate r is 5.60 %.

Based on the data shown in the table, which conclusions can be made about the frequency that customers purchase a genre?
Select each correct answer.
On average, 1 out of 6 customers purchases fantasy books most frequently.
On average, 24% of the customers purchase autobiographies most frequently.
On average, 22% of the customers purchase romance books most frequently.
On average, 2 out of 10 customers, purchase health and wellness books most frequently.
Book Genre Average of Surveys
Autobiographies 24
Mystery 11
Romance 22
Health and Wellness 18
Fantasy 15
Answer:
1/6 customer purchase Fantasy, and 2/10 customers purchase Heath and wellness books.
Step-by-step explanation:
Simply check each number of books over the total than see if it matches the percentage assumed.
Fantasy over total books = 15/90 which is 1/6 So that is correct
Autobiographies over total books = 24/90 = 26.6667 percent which is not what this option said, so not correct.
Romance books over total = 22/90 which equals 24.444 percent which is not equal to the 22 percent option, so also not correct.
And lastly Health and wellness books over total = 18/90 which equals to 20 percent. This is equal to 2/10. So this one is also correct.

The function h(t) = -2(t - 3)2 + 23 represents the height, in feet, t seconds after a volleyball is
served. Which of the following statements are correct? Select all that apply.
The volleyball reached its maximum height at 3 seconds.
The maximum height of the volleyball wag 23 feet.
If the volleyball is not returned by the opposing team, it will hit the ground in 5.5 seconds.
The graph that models the volleyball's height over time is exponential.
The volleyball was served from a height of 5 feet.
Answer:
1,2, and 5
Step-by-step explanation:
The statements about the function that are correct are:
The volleyball reached its maximum height at 3 seconds.
The maximum height of the volleyball was 23 feet.
We have,
The function h(t) = -2(t - 3)2 + 23 represents the height, in feet, t seconds after a volleyball is served.
Let's analyze each statement:
The volleyball reached its maximum height at 3 seconds.
This statement is correct.
The function h(t) is a quadratic function, and its graph is a parabola that opens downwards.
The vertex of the parabola represents the maximum height of the volleyball.
In this case, the vertex occurs when t = 3 seconds.
The maximum height of the volleyball was 23 feet.
This statement is also correct.
We can see from the function that the maximum height occurs at t = 3 seconds, and substituting t = 3 into the function gives:
h(3) = -2(3 - 3)2 + 23 = 23 feet.
If the volleyball is not returned by the opposing team, it will hit the ground in 5.5 seconds.
This statement is incorrect.
To find when the volleyball hits the ground, we need to find when h(t) = 0. Solving -2(t - 3)2 + 23 = 0 gives t = 3 ± √(23/2).
Since the vertex is at t = 3 seconds, the volleyball will hit the ground at the same height it was served, which is h(0) = -2(0 - 3)2 + 23 = 5 feet.
So the time it takes for the volleyball to hit the ground is when h(t) = 0, which occurs at t = 3 ± √(23/2), not 5.5 seconds.
The graph that models the volleyball's height over time is exponential.
This statement is incorrect.
The function h(t) is a quadratic function, not an exponential function.
The volleyball was served from a height of 5 feet.
This statement is also incorrect.
The function h(t) gives the height of the volleyball above the ground, not above the height it was served.
However, we can see from the function that h(0) = -2(0 - 3)2 + 23 = 5 feet, so the volleyball was served from a height of 5 feet above the ground.
Thus,
The statements about the function that are correct are:
The volleyball reached its maximum height at 3 seconds.
The maximum height of the volleyball was 23 feet.

try to find the greatest common factor of both the numerator and denominator.
(a number that you can divide both the top number and bottom number with)
in this case, the greatest common factor is 3. once you divide the numerator and denominator by 3, it leaves you with a fraction 3/4
you can add 1/4 3 times to get 9/12
1/4 +1/4+1/4
or you could just add 1/12 9 times
write a polynomial f(x) of lowest degree that satisfies the given conditions. Zeros: -4, multiplicity 1; 3 multiplicity 2; and f(0)=-108
Answer:
First start with the factors
(3x+5)(3x+5)(6x-1) The multiplicity of 2 means there are 2 of that same factor.
Next, figure out how to get it to go through the point (0,50) Plug in these points, solve for a
50=a(3(0)+5)(3(0)+5)(6(0)-1)
50=a(5)(5)(-1)
50=-25a Divide both sides by -25
-2=a Plug this in
y=-2(3x+5)(3x+5)(6x-1) Now multiply the factors out. Will start by FOILING the first 2 factors
y=-2(9x2+30x+25)(6x-1) Now multiply the remaining factors together
y=-2(54x3+180x2+150x-9x2-30x-25) Combine like terms
y=-2(54x3+171x2+120x-25) Distribute the -2
y=-108x3-342x2-240x+50
