Answer:

49% and 30% respectively

Step-by-step explanation:

Step one:

Given data

Principal =  Rs. 4,200

Final Amount= Rs. 9282 respectively

time = 2 years and

time = 4 years

Required

The rate of interest for 2 and 4 years

Step two:

the compound interest formula is

A= P(1+r)^t

for 2 years

Substitute

\(9282= 4200(1+r)^2\\\\9282/4200= (1+r)^2\)

\(1+r= \sqrt{\frac{9282}{ 4200} }\\\\1+r= \sqrt{2.21} \\\\1+r= 1.49\\\\r=1.49-1\\\\r= 0.49\\\\\)

the rate is 49%

For 4 years we have

\(9282= 4200(1+r)^4\\\\9282/4200= (1+r)^4\)

\(1+r= \sqrt[4]{\frac{9282}{4500} } \\\\1+r=\sqrt[4]{2.21} \\\\1+r= 1.30\\\\r=1.30-1\\\\r= 0.30\\\\\)

the rate is 30%

A rectangle with its base on the x-axis and its vertices on the curve

y =4 - x² can have a maximum area of 32/3√3.

The formula for calculating a rectangle's area is  A=length*breadth

The base's length is x.

y represents the curve's vertices (width).

Given that a rectangle's area increases as its base moves along the x-axis, our base will be 2x.

The rectangle's surface area will change to:

A = 2x ( 4 - x²)

When the area is at its largest, da / dx should be maximum.

A = 8x - 2x³

da/dx = 8 - 6x²

8 - 6x² = 0

6x² =  8

x² = 8/6

x  = √4/3

   =2/√3

We shall substitute 2/√3 into the region in order to obtain the maximum area.

A=  8x - 2x³

  = 8*2/√3 - 2*(2/√3)³

  =32/3√3

Therefore, the largest area a rectangle with a base on the x-axis and vertices on the curve y = 4 - x² can have is 32/3√3.

the total cost is:

$50.72

Answer:

B

Step-by-step explanation:

Ron will have to attend 7 weeks of school this quarter before he will have taken a total of 10 quizzes.

The given equation q = w + 3 represents the relationship between the total number of quizzes Ron has ever taken (q) and the number of weeks he has attended school this quarter (w). According to the equation, for each week Ron attends school, he takes one additional quiz.

To find the number of weeks of school Ron needs to attend before he will have taken a total of 10 quizzes, we can substitute the value of q (10) into the equation and solve for w.

10 = w + 3

Subtracting 3 from both sides of the equation, we have:

w = 10 - 3

w = 7

Therefore, Ron will have to attend 7 weeks of school this quarter before he will have taken a total of 10 quizzes.

Answer:

a. 7 times

b. 74.7 km

Step-by-step explanation:

a. From Albany to Pittsburgh, there are 739.7 km.

She stopped to rest after every 95 kilometres:

Therefore, let us find how many times she stopped:

739.7 / 95 = 7.79

We only need the quotient, that is, 7

So she stopped 7 times.

b. After her last stop, she had traveled:

7 * 95 = 665 km

Therefore, the distance she has left after her last stop is:

739.7 - 665 = 74.7 km

In the given study comparing the effects of regular-fat cheese to reduced-fat cheese on LDL cholesterol levels, the dependent variable(s) refers to the outcome(s) that are being measured or observed. In this case, the dependent variable in this study is: b. LDL levels

The dependent variable is the variable that is measured or observed to assess the effect of the independent variable(s). In this case, the study is comparing the effects of regular-fat cheese and reduced-fat cheese on LDL cholesterol levels.

LDL cholesterol levels are the outcome being measured to determine the impact of the different types of cheese on cholesterol. Therefore, option b, LDL levels, is the dependent variable in this study. Options a (regular fat cheese) and c (reduced fat cheese) are not the dependent variables but rather the independent variables, as they are the different conditions being compared to assess their effect on LDL levels.

Option d (both a and b) and option e (both b and c) are incorrect because regular-fat cheese (option a) is an independent variable, not a dependent variable.

Janice's estimate of the longest side of the triangle being 25 units, assuming it is a right triangle, is approximately correct.

Janice's estimate of the longest side being 25 units, if it is a right triangle, is exactly correct. A right triangle is a triangle with one angle measuring 90 degrees, and it follows the Pythagorean theorem, which states that the square of the length of the hypotenuse (the longest side) is equal to the sum of the squares of the other two sides. In this case, if the longest side is indeed 25 units, it means that the square of 25 is equal to the sum of the squares of the other two sides.

Therefore, if Janice estimated the longest side to be 25 units, assuming it is a right triangle, and this estimate aligns with the actual length of the longest side, then her estimate is exactly correct. It is neither under nor overestimated.

Answer: 26 minutes

Step-by-step explanation:

Assume that the total time spent in the morning which includes getting dressed, eating breakfast, making her bed, and driving to work is x.

Time getting dressed = ¹/₃x

Eating breakfast = 10 mins

Making bed = 5 mins

¹/₃x + 10 + 5 = 35 ½

¹/₃x + 15 = 35 ½

¹/₃x = 35 ½ - 15

¹/₃x = 20 ½

x = 20 ½ / ¹/₃

= 61.5 minutes

Total morning routine is is 61.5 mins

Time taken to drive to work is;

Answer:

I may be late on this but the answer is 5/4

Step-by-step explanation:

The co-domain of T is R2. So the correct option is: R2.

In linear algebra, a linear transformation is a function that maps vectors from one vector space to another while preserving certain properties.

In this case, the given linear transformation T takes a vector in \($\mathbb{R}^3$\) as input and outputs a vector in \($\mathbb{R}^2$\).

The notation T: \($\mathbb{R}^3$\) \($\to$\) \($\mathbb{R}^2$\) indicates that the domain of T is \($\mathbb{R}^3$\) and the co-domain (or range) is \($\mathbb{R}^2$\).

The co-domain is the set of all possible output values that can be obtained from the linear transformation.

The co-domain of a linear transformation is the set of all possible outputs that can be obtained by applying the transformation to any input.

In this case, the linear transformation T maps a vector in R3 to a vector in R2.

Therefore, the co-domain of the given linear transformation T is \($\mathbb{R}^2$\), which means that the output of T is a two-dimensional vector.

Answer: 2b = 3g

Step-by-step explanation:

This is quite basic to solve, below is a Step by step explanation:

from the given question we have that;

       i.e  b = 1500 gallons per minute

          g = 1000 gallons per minute.

Our questions tells us to write the equation which  relates the flow of water from the blue hydrant, b, to the flow from the green hydrant, g.

ANS:

Since flow from blue  hydrant b = 1500 gallons per minute, we have that

b = 3 * 500

b = 3 * 1000/2 g

b = 3/2 g

equation  gives 2b = 2g

The area of the field is 10,765.44 square meters.

Given that:

Diameter, d = 72 m

Width, W = 72 m

Length, L = 93 m

The area of a two - dimensional figure is the area that its perimeter encloses. The quantity of unit squares that occupy a closed figure's surface is its region.

The area of the field is calculated as,

A = (π/4)d² + W·L

A = (3.14 / 4) x 72² + 72 x 93

A = 4,069.44 + 6,696

A = 10,765.44 square meters

The side lengths of A'A and B'B are 18 and 9 respectively.

When the respective sides are proportional and the corresponding angles are congruent, two triangles are said to be similar.

Given that, segment A'B' is parallel to segment AB.

Let A'A =x and B'B = y.

Since the segments are parallel the triangles ΔA'B'C and ΔABC are similar.

As per the property of similar triangles, it follows:

12/8 = (12 + x)/20

12 + x = (12/8)20

x = 18

And,

6/8 = (6+y)/20

6 + y = (6/8)20

y = 9

Hence, the side lengths of A'A and B'B are 18 and 9 respectively.

The balanced chemical equation for the reaction between aluminum metal (Al) and hydrochloric acid (HCl) is:

Aluminum chloride is a chemical compound with the chemical formula AlCl3. When contaminated with iron chloride, it often displays a yellow color compared to the white pure compound. It is used in various chemical applications as a Lewis base, with anhydrous aluminium trichloride being the most commonly used Lewis acid.

Hydrochloric acid (HCl) is commonly used for the neutralization of alkaline agents, as a bleaching agent, in food, textile, metal, and rubber industries. It is neutralized if released into the soil and it rapidly hydrolyzes when exposed to water.

2 Al + 6 HCl → 2 AlCl3 + 3 H2

In this equation, 2 moles of aluminum react with 6 moles of hydrochloric acid to produce 2 moles of aluminum chloride and 3 moles of hydrogen gas. Therefore, the coefficient of hydrogen gas (H2) is 3. This means that for every 2 moles of aluminum reacting, 3 moles of hydrogen gas are produced.
