Answer:

a) The next two terms are: 13, 16

b) nth term of the sequence is [tex]\mathbf{a_n=3n-5}[/tex]

Step-by-step explanation:

a) Find the next two terms of sequence: -2,1,4,7 and 10

The common difference d: a₂-a₁ = 1-(-2)= 3

a₃-a₂= 4-1 = 3

a₄-a₃=7-4=3

So, common difference is : 3

Next two terms are: 10+3 = 13

13+3= 16

The next two terms are: 13, 16

b) Find nth term of the sequence

The nth term can be found using formula:

[tex]a_n=a_1+(n-1)d[/tex]

where a₁=First term and d=Common Difference

In the sequence given we have a₁=-2 and d=3

So, the nth term will be:

[tex]a_n=a_1+(n-1)d\\a_n=-2+(n-1)3\\a_n=-2+3n-3\\a_n=3n-5[/tex]

So, nth term of the sequence is [tex]\mathbf{a_n=3n-5}[/tex]

The trapezoid is isosceles and NK is its height, therefore

Since ∠KDN = 45°, the triangle NKD is isosceles and so

MF  = ND as trapezoid is isosceles and therefore diagonals are equal

Answer:

= 0.312

Solution:

Change the divisor 6.410251 to a whole number by moving the decimal point 6 places to the right. Then move the decimal point in the dividend the same, 6 places to the right.

We then have the equations:

2000000 ÷ 6410251 = 0.312

and therefore:

2 ÷ 6.410251.6109 1) = 0.312

Both calculated to 3 decimal places.

There is 1 tree per 1.6 acre.

Step-by-step explanation:

Divide the number of trees from the number of acres. This will tell you how many acres are between each tree.

Answer:

0.6 acres.

Step-by-step explanation:

You divide the total population of the willow tree (30) by the areas they occupy (50 acres). Therefore, 30/50=0.6 population per acre.

The answer is  ( D ),   y ≤ 6

The range begins from minimum value to maximum value.

However, in the graph. There's no minimum value as it's heading toward negative infinity.

So we use y ≤ 6 instead.

So the clear answer is y ≤ 6 or ( D )

Answer: Amount borrowed at 9% = 9,428.57

Amount borrowed at 7% = $18,857.14

Amount borrowed at 10% = $ 21,714.29

Step-by-step explanation:

Formula for simple interest :

I = PRT,

P= Principal, R =rate , T= time

Let x = amount borrowed at 9%.

y = amount borrowed at 7%.

z = amount borrowed at 10%.

i.e. x+y+z= 50000    (i) [Given : amount invested = 50000]

Interest on x = x (0.09)(1)   [as P=x,  T=1 year, r= 0.09]

= 0.09x

Similarly

Interest on y = y(0.07)(1) = 0.07y

Interest on z = z(0.1)(1)=0.1z

Total interest = 0.09x+0.07y+0.1z = 4340   (ii)

Also, y=2x   [given]  (iii)

Put y=2x in (i) and (ii), we get

x+2x+z= 50000 ⇒ 3x+z=50000    (iv)

0.09x+0.07(2x)+0.1z=4340  ⇒ 0.09x+0.14x+0.1z=4340

⇒ 0.23x+0.1z=4340    (v)

Multiply 10 on both sides of (v)

2.3x+z=43400   (vi)

Eliminate (vi) from (v)

0.7x=6600

⇒ x= 9,428.57

From (iii), y= 2(9428.57) =18,857.14

From (vi),

2.3(9428.57)+z=43400

⇒ 21685.71+z=43400

⇒ z= 43400-21685.71

⇒ z=21714.29

Hence, Amount borrowed at 9% = 9,428.57

Amount borrowed at 7% = $18,857.14

Amount borrowed at 10% = $ 21,714.29

Answer: 32.0%

Step-by-step explanation:

The price of car last month = $250

The price of the car this month = $330

Increase in price = $330 - $250 = $80

Percentage increase = (Increase in price/Cost price last month) × 100

= $80$250 × 100

= 0.32 × 100

= 32.0%

The percent of increase in the price of the car is 32.0%.

Answer:

Ok to make this easier for us we should switch these equations into y=mx+b so that it's easier for us to identify the slope and y-intercept:

to switch into y=mx+b form do this:

3x-y=5

-y=5-3x

y=-5+3x

y=3x+(-5)

2y-15x=8

2y=8+15x

y=4+7 1/2x

y=7 1/2x+4

THe slope of any line in y=mx+b form is m. Therefore in this equation:

y=3x+(-5)     3 is the slope

The y intercept of any line is the +b:

y=7 1/2x+4 -therefore 4 in this equation is our y intercept.

Now we can construct our equation in y=mx+b then into standard form (Ax+By=C)

since 3 is our slope and 4 is our y intercept the equatuon is :

y=3x+4

NOw all we need to do is move this into standard form:

y=3x+4

-3x+y=4

-3x+y=4 is your final answer

Answer:he should build them 25x10

Step-by-step explanation:

Encik Ahmad can build 10 square plots with three different sizes.

Rectangle is a polygon in two dimensional geometry which has four sides and four angles and each angle being right angles.

Length of the rectangular plot = 85 m

Width of the rectangular plot = 30 m

We have to find the number of square plots Encik Ahmad can built of three different sizes.

For that first we take a 45 m length of the plot.

Divide it to three equal lengths. We get three lengths with each 15 m length.

Along the width also, divide into two equal width, each having a width of 15 m.

Each 15 m length, we will get two square plots.

Along 45 m length, we get 3 × 2 = 6 square plots.

The remaining rectangle has length 40 m and width 30 m.

Divide this length as 30 m and 10 m.

So we get a square of dimension 30 m.

Remaining is a rectangle whose remaining length is 10 m and width 30 m.

Along the width, divide into three equal widths, each 10 m.

So there we get three square plots with side length 10 m.

So we have 10 square plots, 6 having the side length 15m, 1 having the side length 30 m and 3 having the side length 10 m.

Hence he get 10 square plots having three different sizes as 15 m, 30 m and 10 m.
