The reciprocal is the fraction flipped. so the reciprocal of 1/2 is 2/1. It's used when dividing fractions to make it multiplication, so you use the reciprocal for the second fraction.

Can someone please help me with this
natta225 [31]

Answer:

(a)\ (1,5)

Step-by-step explanation:

Given

(x + 9)^2 + (y - 4)^2 = 101

Required

Which of the points does it pass through

To do this, we simply substitute the values of x and y in the above equation.

So, we have:

(a)\ (1,5)

(x + 9)^2 + (y - 4)^2 = 101

(1 + 9)^2 + (5 - 4)^2 = 101

Solve each bracket

10^2 + 1^2 = 101

100 + 1 = 101

101 = 101

The above equation is true,

<em>Hence, it passed through </em>(1,5)

<em>We do not need to check for others</em>

Solve the proportion for N:
laila [671]
For the first three questions
5/12 = 35/N
Rearrange: N = 35 / (5/12) = ( 35 / 0.4167 ) = N = 83.99

7/18 = N / 9
Rearrange: N = (7/18)* 9 = 3.5

(2/5) * 240 = 96

2cos^2x+3cosx-2=0 ...?
VARVARA [1.3K]
Its like a polynomial.
 
cosx=x

so it'll be like

2x^2+3x-2=0

<span>(2x−1)(x+2)
</span>
which makes your life easy because you do not have to solve cos(x)=−2 because it cannot be, so only solve cos(x)=1/2
