This question is incomplete, the diagram is missing. The complete diagram is uploaded along this answer.

Answer: (3) 2.5

Step-by-step explanation:

From the diagram, given that;

BF = 2.3, DF = x, FC = 5, FE = 4.6,

Now

by theorem

BF * FC = DF * FE

so we substitute

2.3 * 5 = x * 4.6

11.5 = 4.6x

x = 11.5 / 4.6

x = 2.5

therefore the value of x is 2.5

Answer:

(-6,8)

Step-by-step explanation:

2x + 9y = 60

-9x + y = 62 --> y = 9x + 62 --> 2x + 9(9x + 62) = 60 -->

2x+ 81x + 558 = 60 -->

83x + 558 = 60 -->

83x = -498 -->

x = -6 -->

y = 9(-6) + 62 -->

y = 8

The area of a circle is 80.86cm2. Find the length of the radius rounded to 2 DP.

weeeeeb [17]

Answer:

Solution given:

The area of a circle =80.86cm²

we have:

The area of a circle =πr²

substituting value of area of circle we get

80.86cm=3.14*r²

dividing both side by 3.14

80.86/3.14=3.14*r²/3.14

25.75=r²

doing square root on both side

$\sqrt{25.75}=\sqrt{r²}$

r=5.07cm

The length of radius is 5.07cm

The amount of money in Nadia’s savings account is represented by the recursive formula an=1.025(an-1)+50 if a6=291.51 what are t

Elis [28]

Recursive formula is one way of solving an arithmetic sequence. It contains the initial term of a sequence and the implementing rule that serve as a pattern in finding the next terms. In the problem given, the 6th term is provided, therefore we can solve for the initial term in reverse. To make use of it, instead of multiplying 1.025, we should divide it after deducting 50 (which supposedly is added).

Therefore, we perform the given formula: A (n) = 1.025(an-1) + 50
a(5) =1.025 (235.62) + 50 = 291.51

a(4) = 1.025 (181.09) + 50 = 235.62

a(3) = 1.025 (127.89) + 50 = 181.09

a(2) = 1.025 (75.99) + 50 = 127.89

a(1) = 1.025 (25.36) + 50 = 75.99

a(n) = 25.36

The terms before a(6) are indicated above, since a(6) is already given.

So, the correct answer is A. $25.36, $75.99.
