F(x) = 3x + 11
Is the function used to show this.

when you know this, you are able to do the following:
f(10) = 30 + 11 = $41
That would be the allowance of the 10th week.

The question, however wants the total.

This again, can be done like this:
f(1) + f(2) + f(3) + f(4) + f(5) + f(6) + f(7) + f(8) + f(9) + f(10) = $275 :)
14 + 17 + 20 + 23 + 26 + 29 + 32 + 35 + 38 + 41 = $275

Sure there is a better formula, but i couldnt seem to make it, sorry.

HUGE UPDATE: The sum is $275 not 200..

Find two consecutive odd integers whose product is 899

UNO [17]

Answer:

Step-by-step explanation:

Let two consecutive odd numbers

x, x+2

According to condition

X(x+2) = 899

x2 +2x -899=0

X2 +31x -29x -899=0

x(x+31) -29(x+31)=0

(x+31)(x-29)=0

X=-31 or x =29

Now,

X=29

X+2= 29+2 = 31

Two consecutive odd numbers is 29 and 31

2. The radius of a circle is 7cms. The angle subtended by an arc of the circle at centre is 45º. Find the area of sector.

Vitek1552 [10]

Answer:

19.2cm²

Step-by-step explanation:

Given parameters:

Radius of the circle = 7cm

Angle subtended by the arc = 45°

Unknown:

Area of the sector = ?

Solution:

To find the area of the sector, use the expression below;

Area of sector = $\frac{Angle of the arc}{360} x \pi r^{2}$

where r is the radius ;

Insert the parameters and solve;

Area of sector = $\frac{45}{360}$ x $\pi$ x 7²

Area of sector = 19.2cm²
