Which of the following has a greater area ?A parallelogram with one side 24 cm and the distance between parallel sides 9cm or a quadrilateral having one diagonal 24cm and the perpendiculars to the diagonal are 9cm and 12cm |
Answer» ★ Procedure :Here, we are given TWO quadrilaterals :
In order to find which one have greater AREA, we have to calculate the area of both shapes. To calculate the area of parallelogram, we'll use the formula : Base × height. To calculate the area of the irregular quadrilateral, we'll divide into two triangles and will find by adding the area of both triangles. After that, we'll compare which one has greater area. Solution:~ Area of parallelogram :Given: • Measure of one side (say base) = 24 cm • Distance between parallel sides (Height) = 9 cm Therefore, → Area of ||gm = Base × Height → Area of ||gm = 24 cm × 9 cm → Area of ||gm = 216 cm ² ~ Area of quadrilateral having one diagonal 24cm and the perpendiculars to the diagonal are 9cm and 12cm :Let us draw a rough diagram first (Refer to the attachment : Fig B). Clearly, ABD & CBD are two triangles. Henceforth, → Area of quadrilateral = Area of ( ∆ ABD & ∆ CBD ) cm² → Area of quadrilateral = (½ × b × h) + (½ × b × h) cm² → Area of quadrilateral = (½ × 9 × 24) + (½ × 12 × 24) cm² → Area of quadrilateral = (1 × 9 × 12) + ( 1 × 6 × 24 ) cm² → Area of quadrilateral = ( 108+144 ) cm² → Area of quadrilateral = 252 cm² Therefore, area of quadrilateral having one diagonal 24cm and the perpendiculars to the diagonal are 9cm and 12cm has greater area. |

= f 1
1
= 0.25 1
=4D f 2
=−10cm=−0.1m P 2
= f 2
1
= −0.1 1
=−10D (a) Power of the COMBINATION : P=P 1
+P 2
=4D+(−10D) =−6D (b) Focal length of the combination: f= P 1
= −6 1
=−0.1666m=−16.66cm (c) The combination has negative focal length , so it is DIVERGING. |

The amount of money in an account may increase due to rising stock prices and decrease due to falling stock prices.mason is studying the change in the amount of money in two accounts, a and b, over time. the amount f(x), in dollars, in account a after x years is represented by the function below: f(x) = 10,125(1.83)x part a: is the amount of money in account a increasing or decreasing and by what percentage per year? justify your answer. (5 points) part b: the table below shows the amount g(r), in dollars, of money in account b after r years. r (number of years) 1 2 3 4 g(r) (amount in dollars) 9,638 18,794.10 36,648.50 71,464.58 which account recorded a greater percentage change in amount of money over the previous year? justify your answer. |
|
Answer» Answer: Account A: Decreasing at 8 % per year Account B: Decreasing at 10.00 % per year The amount f(x), in dollars, in account A after x years is REPRESENTED by the function below: f(x) = 10,125(1.83)x Account B shows the greater percentage change Step-by-step explanation: Part A: Percent change from exponential formula f(x) = 9628(0.92)* The general formula for an exponential function is y = ab^x, where b = the base of the exponential function. if b < 1, we have an exponential decay function. f(x) DECREASES as x increases. Account A is decreasing each year. We can rewrite the formula for an exponential decay function as: y= a(1 – b)”, where 1- b = the decay factor b = the percent change in decimal form If we compare the two formulas, we find 0.92 = 1- b b = 1 - 0.92 = 0.08 = 8 % The account is decreasing at an annual rate of 8%. The account is decreasing at an annual rate of 10.00%. Account B RECORDED a greater percentage change in the amount of money over the previous year. |

Two years ago son's age was 1/17th the age of his father, four years hence it will be 1/5th.Find the present ages.40 The son's age is 1/9th of his father, four years hence it will be 1/5th. Find the present ages. |
|
Answer» Answer: Let the FATHER PRESENT AGE =x years and son present age =y years According to the first condition 5 years later father will be (x+5) years old and son will be (y+5) years old. ⇒x+5=3(y+5) ⇒x+5=3y+15⇒x=3y+10....eq1 According to the second condition 5 years ago father was (x−5) years old and son was (y−5) years old. ⇒x−5=7(y−5) ⇒x−5=7y−35 ⇒x−7y=−30....eq2 Put the value of x from eq1 ⇒3y+10−7y=−30⇒−4y=−40⇒y=10 Put y=10 in eq1 ⇒x=3×10+10=40
Hence, Father present age =40 years Son present age =10 years |
