Answer:  504 cm^2

The surface area of the shape is:

3 3 * 3=9

9 * 7=63

63+9=72 * 7

=504cm^2

Raju is cycling at a speed of 30km/h. He applies brakes and stops at a junction in 10s. Calculate the acceleration.
Sedbober [7]

Answer:

Acceleration = 3m/s²

Step-by-step explanation:

Here ,

Initial velocity = 30km/h

Final velocity = 0km/h

Time = 10s

Acceleration = ?

We know ,

A = v-u/t

or , A = 0-30/10

or, A = 30/10

A = 3m/s²

Therefore the acceleration is 3m/s²

Help asap will give brainliest!!!!
GarryVolchara [31]

Answer:

C

Step-by-step explanation:

ley y = f(x) and rearrange making x the subject

y = \frac{1}{x+5} - 1 ( add 1 to both sides )

y + 1 = \frac{1}{x+5} ( multiply both sides by (x + 5)

(y + 1)(x + 5) = 1 ← expand factors using FOIL

xy + 5y + x + 5 = 1 , that is

xy + x + 5y + 5 = 1 ( factor first/second and third/fourth terms on left side )

x(y + 1) + 5(y + 1) = 1 ← factor out (y + 1) from each term on left side

(y + 1)(x + 5) = 1 ( divide both sides by (y + 1) )

x + 5 = \frac{1}{y+1} ( subtract 5 from both sides )

x = \frac{1}{y+1} - 5

Change y back into terms of x with x = f^{-1} (x) , then

f^{-1} (x) = \frac{1}{x+1} - 5 where x ≠ - 1

Which equation represents a line that passes through the two points in the table x 1,5 and y 1,6
aleksandrvk [35]

For this case we must find a linear equation of the form:

y = mx + b

Where,

m: slope of the line

b: cutting point with vertical axis.

For the slope we have the following equation:

m = \frac {y_ {2} -y_ {1}} {x_ {2} -x_ {1}}

Substituting values we have:

m = \frac {6-5} {1-1}\\m = \frac {1} {0}

We observe that the slope of the line is not defined.

Therefore, the line is vertical.

Thus, the equation of the line is given by:

x = 1

Answer:

The equation of the line is given by:

x = 1

Find the student’s error in solving the following inequality.
Leto [7]

Answer:

The student should have switched the direction of the inequality sign to

get –5 > x for a final answer.

Step-by-step explanation:

When multiplying or dividing an inequality by a negative "flip" the inequality sign

The student should have switched the direction of the inequality sign to

get –5 > x for a final answer.

---------------

Note:

For a more conventional appearance the entire inequality can be flipped to

–5 < x
