Answer:

y = x + 2

Step-by-step explanation:

1.) identify the gradient in the given equation

M1= -1

2.) use the formula to find the next gradient

formula: M1 × M2 = -1

-1 × M2 = -1 ( divide by -1 on both side)

M2 = 1

3.)use the formula

y - y1 = m(x - x1)

y - 6 = 1 ( x- 4)

y - 6 =1x -4(add 6 on both side)

y = x + 2

Answer:

Step-by-step explanation:

F(x) = 2^x

64 = 2^x

2^6 = 2^x

x = 6

f(x) = 2^x

log (f(x)) = x log 2

x = log (f(x)) / log 2 = log_2 (f(x))

Therefore, the required logarithmic function is x = log_2 (f(x))

The cost of a circular table is directly proportional to the square of the radius. A circular table with a radius of 50cm costs
Lana71 [14]

Answer:

£135 is the correct answer.

Step-by-step explanation:

Let C be the cost of table.

And let R be the radius of table.

Cost of table is directly proportional to square of radius.

As per question statement:

C\propto R^{2} or

C=a\times R^2  ....... (1)

where a is the constant to remove the \propto sign.

It is given that

C_1 = £60 and R_1 = 50\ cm

C_2 = ? when R_2= 75\ cm

Putting the values of C_1 and R_1 in equation (1):

60=a \times 50^2  ....... (2)

Putting the values of C_2 and R_2 in equation (1):

C_2=a \times 75^2  ....... (3)

Dividing equation (2) by (3):

\dfrac{60}{C_2}= \dfrac{a \times 50^2}{a \times 75^2}\\\Rightarrow \dfrac{60}{C_2}= \dfrac{50^2}{75^2}\\\Rightarrow \dfrac{60}{C_2}= \dfrac{2^2}{3^2}\\\Rightarrow \dfrac{60}{C_2}= \dfrac{4}{9}\\\Rightarrow C_2 = 15 \times 9 \\\Rightarrow C_2 = 135

So, <em>£135 is the correct answer</em>.

I dont understand what the question is asking me​
kipiarov [429]

Answer:

\huge\boxed{\sf

Step-by-step explanation:

∠E = 1/2 (mCD - mAB)

<u>Where mCD = 110° and mAB = 30°</u>

∠E = 1/2 (110° - 30°)

∠E = 1/2 (80°)

∠E = 40°

\rule[225]{225}{2}

Hope this helped!
