The answer to this question is the letter b) , c) and F)

Because, when x = 6

y = 6 × 6

y = 36

Then, the ordened pairs would be:

(x, y) = (6,36) <=> When x = 7 <=> Y = 6 × 7 <=> 42 And <=> When x = 15 <=> Y = 6 × 15 <=> Y = 90 <=> (x, y) = (15,90)

Answer:

m = 10\sqrt 3

n = 10

Step-by-step explanation:

Required

Find m and n

Considering the given angle, we have:

\sin(60) = \frac{Opposite}{Hypotenuse}

This gives:

\sin(60) = \frac{m}{20}

Make m ths subject

m = 20 * \sin(60)

\sin(60) =\frac{\sqrt 3}{2}

So, we have:

m = 20 *\frac{\sqrt 3}{2}

m = 10\sqrt 3

Considering the given angle again, we have:

\cos(60) = \frac{Adjacent}{Hypotenuse}

This gives:

\cos(60) = \frac{n}{20}

Make n the subject

n = 20 * \cos(60)

\sin(60) =\frac{1}{2}

So, we have:

n = 20 *\frac{1}{2}

n = 10

Remember to distribute invibile -1
simlify 2nd part
-(a^2-3a+7)=-1(a^2-3a+7)=-a^2+3a-7

now we have
3a^2+2a-2-a^2+3a-7=
3a^2-a^2+2a+3a-2-7=
2a^2+5a-9

The value of y varies directly with the value of x. When y = 15, x = 3. What is the value of x when y = 60?
Viefleur [7K]
The answer is B
because at first y was equal to 15 and x equaled to 3 the quotient of 15/3 = 5.
now the y is 60 so, 60/5 = 12

Answer:

g = 81.

Step-by-step explanation:

f = k/√g    where k is a constant

When f = 12 g = 36, so:

12 = k/√36 = k/6

k = 12*6 = 72.

So the relation is:

f = 72/√g

When f = 8:

8 = 72/√g

8√g = 72

√g = 72/8 = 9

g = 9^2 = 81.
