Answer 1

Answer:

b or B is correct answer out of all

Answer 2

Answer:

I'll try my best to answer this but it could be A. and B.

Step-by-step explanation:

The reasoning for this is because both A and B show correct number lines and the question is asking to select TWO that applyFor A., -2 is the opposite of 2

»(-2 is on the left side of the number line, the left side of number lines show negative numbers)

This same rule applys to B. -4 is the opposite of 4.

The reason why C. wouldn't be right is because -3 is on the same side where positive numbers would go, on the right side of 0. Meaning C. isn't a correct number line so it can't be the right answer..

I hope this helped!!

Solve for n.
d=4m + 7n
n

Answers

Answer:

n = [tex]\frac{d-4m}{7}[/tex]

Step-by-step explanation:

Given

d = 4m + 7n ( subtract 4m from both sides )

d - 4m = 7n ( isolate n by dividing both sides by 7 )

[tex]\frac{d-4m}{7}[/tex] = n

Answer:

n = d - 4m ÷ 7

Step-by-step explanation:

d = 4m + 7n

d - 4m = 7n

7n = d - 4m

n = d - 4m ÷ 7

Thus, n = d - 4m ÷ 7

Answer:

C. the rate at the pool fills in feet per hour

Step-by-step explanation:

Given

The attached graph

Required

What does the slope represent?

The slope of any graph can be calculated using:

[tex]Slope = \frac{Rise}{Run}[/tex]

Where:

Rise = The change in the vertical axis

Run = The change in the horizontal axis within the same interval as the Rise

The vertical axis measures depth in feet and the horizontal axis measures time in hour.

So:

[tex]Slope = \frac{Depth}{Time}[/tex]

or

[tex]Slope = \frac{Feet}{Hour}[/tex]

This means that the slope measures rate in feet per hour

In your biology class, your final grade is based on several things: a lab score, scores on two major tests, and your score on the final exam. There are 100 points available for each score. However, the lab score is worth 21% of your total grade, each major test is worth 24%, and the final exam is worth 31%. Compute the weighted average for the following scores: 90 on the lab, 98 on the first major test, 71 on the second major test, and 79 on the final exam.

the weighted score is 82.03

Step-by-step explanation:

The computation of the weighted score is as follows

= Respective scores × respective test or exam and score

= 0.21 × 90 + 0.24 × 71 + 0.24 × 71 + 0.31 × 79

= 18.9 + 21.6 + 17.04 + 24.49

= 82.03

Hence, the weighted score is 82.03

equation of the line through point (5,4) and perpendicular to y=−4/3x−2.

Answers

Answer:

y=3/4x+1/4

Step-by-step explanation:

Perpendicular lines have slopes that are negative and reciprocal. If you multiply them together, the result is -1.

So, to find the slope of the new line, we can use this equation:

-4/3m=-1

multiply both sides by 3/-4

m=3/4

So the slope of the new line is 3/4

Here's the equation so far:

y=3/4x+b (b is a placeholder)

we can substitute the point (5,4) into the equation, since the line is going to pass through it.

4=3/4(5)+b

4=15/4+b

1/4=b

So the line is y=3/4x+1/4

Hope this helps!

31.4 times a number

=> 31.4 * n

plus negative 8.4

=> 31.4n -8.4

Equals to twenty-four

=>  31.4n -8.4 = 24

A circle has an area of 256 square inches. If the radius of
the circle is multiplied by 4, what will be the area of the new
circle formed?
OA) 890 in.
OB) 1520 in.
OC) 4096 in
OD 5360 in.

Answers

Answer:

Option C (4096π in²)

Step-by-step explanation:

Area of the circle = 256π in²

We know that [tex]Area=\pi r^{2}[/tex] , where r = radius of the circle

So,

[tex]256\pi = \pi r^{2}[/tex]

Cancelling π from both the sides,

[tex]=> r^{2} = 256[/tex]

[tex]=> r = \sqrt{256} = 16[/tex]

The radius of the circle = 16 in.

When the radius is multiplied with 4 , new radius = 16×4 = 64 in.

New Area = [tex]\pi (64)^{2} =4096\pi \: in^{2}[/tex]

A zookeeper took a random sample of 30 days and observed how much food an elephant ate on each of those days. The sample mean was 350 kg and the sample standard deviation was 25 kg. Find the 95% confidence interval for how much food the elephant eats.

Answers

Answer:

341.95≤x≤358.95

Step-by-step explanation:

The confidence interval formula is expressed as;

CI = xbar±(z×s/√n)

xbar is the mean sample

s is the standard deviation

z is the z score at 95% confidence interval

n is the sample size

xbar = 350kg

z = 1.96

s = 25kg

n = 30

Substitute

CI = 350±(1.96×25/√30)

CI = 350±(1.96×4.564)

CI = 350±(8.946)

CI = (350-8.946, 350+8.946)

CI = (341.05, 358.95)

Hence the 95% confidence interval for how much food the elephant eats us 341.95≤x≤358.95

50!!! Points Paul needs 27 plants to fill his garden and has $99 to
spend. Lilies cost $5 each and tulips cost $2 each. Which
system represents the number of lilies (1) and tulips (t)
Paul can buy?

Answers

Answer:

[tex]\boxed{\boxed{\pink{\bf \leadsto Option \ A \ is \ correct .}}}[/tex]

Step-by-step explanation:

Given that , Paul needs 27 plants to fill his garden and has $99 to spend. Lilies cost $5 each and tulips cost $2 each.

Tulips are represented by t .Lilies are represented by l .

Now we need to find which set of linear equations represent the above situation. So ,

Sum of number of lilies and tulips is 27 .

[tex]\implies \bf n( Tulips) + n(Lilies ) = 27 \\\\\bf\implies \boxed{ \bf l + t = 27 }[/tex]

Now , cost of each lily is $5 and tulip is $2 . And he has $99 in total . So ,

[tex]\bf\implies n_{tulips} \times cost_{tulip} + n_{lilies} \times cost_{lilies} = Money \ that \ Paul \ has. \\\\\bf \implies t\times \$2 + l \times \$5 = \$ 99 \\\\\implies \boxed{\bf 2t + 5l =\$ 99 }[/tex]

Hence we can see that our ans matches with option (a) which is ,

[tex]\red{\bf Option \ A}\begin{cases} \bf l + t = 27 \\\\\bf 2t + 5l = 99 \end{cases}[/tex]

Hence option (A) is correct .

inverse laplace of L^-1 {5s/s^2 + 3s - 4}​

Answers

Answer:

[tex]L^{-1} (\frac{5s}{s^{2}+ 3 s -4 } )[/tex] =  [tex]4e^{-4t} + e^{t}[/tex]

Step-by-step explanation:

Step(i):-

Given

           [tex]L^{-1} (\frac{5s}{s^{2}+ 3 s -4 } )[/tex]

Factors of    s² + 3s - 4

               =    s² + 4s - s -4

               =   s( s +4 ) -1 (s +4)

               =   (s-1)(s+4)

  [tex]L^{-1} (\frac{5s}{s^{2}+ 3 s -4 } )[/tex]

              =    [tex]L^{-1} (\frac{5s}{s+4)(s-1) } )[/tex]

By using partial fractions

           [tex](\frac{s}{s+4)(s-1) } ) = \frac{A}{s+4} + \frac{B}{s-1}[/tex] ..(i)

                s  = A ( s-1) + B( s+4) ....(ii)

          Put s= 1  in equation (ii) , we get

             1 = B(5)

           [tex]B = \frac{1}{5}[/tex]

         s = -4 in equation (ii) , we get

        -4 = -5A

         [tex]A =\frac{4}{5}[/tex]

Step(ii):-

    now the equation (i) , we get

[tex](\frac{s}{s+4)(s-1) } ) = \frac{4}{5(s+4)} + \frac{1}{5(s-1)}[/tex]

[tex]L^{-1} (\frac{s}{s+4)(s-1) } ) = 5( L^{-1} \frac{4}{5(s+4)} + 5L^{-1} \frac{1}{5(s-1)}[/tex]                      

By using inverse Laplace transform formula

[tex]L^{-1} (\frac{1}{s-a} ) = e^{at}[/tex]

[tex]L^{-1} (\frac{1}{s-1} ) = e^{t}[/tex]

[tex]L^{-1} (\frac{1}{s+4} ) = e^{-4t}[/tex]

[tex]L^{-1} (\frac{s}{s+4)(s-1) } ) = 5( L^{-1} \frac{4}{5(s+4)} + 5L^{-1} \frac{1}{5(s-1)}[/tex]                    

                      = [tex]4e^{-4t} + e^{t}[/tex]

Step-by-step explanation:

Given that:

Length of bed = 120 in

Width of bed = 240 in

Perimeter of a rectangle is given by :

P = 2(length + Width)

Therefore,

P = 2(120 + 240)

Perimeter = 720 inches

If a spacing of 16 inches will be used ; number of plants needed ;

Perimeter / 16
