The runner covers a 100 meters in 9.7 seconds. What is her speed?

mestny [16]

Answer:

10.3 m/s

Step-by-step explanation:

Speed = Distance / Time

100 metres travelled in 9.7 seconds means that her speed was 100/9.7 metres per second, which is 10.30927... rounded to 10.3 metres per second.

4. a) A load of 1000N can be lifted by applying an effort of

miv72 [106K]

Step-by-step explanation:

load=1000N

effort=250N

load arm=25cm

effort arm=?

Now,

E×E.D=L×L.D

250×E.D=1000×25

E.D=1000×25÷250

E.D=100cm

therefore,effort arm is 100cm.

Identify the reflection rule on a coordinate plane that verifies that triangle A(-1,7), B(6,5), C(-2,2) and A'(-1,-7), B'(6,-5),

malfutka [58]

Answer:

Option B is correct.

The reflection rule is followed here is, $(x,y) \rightarrow (x, -y)$ .

Explanation:

Since, the triangle is reflected over the x-axis , then only y- coordinates will get changed but the x coordinates will remain the same.

$A(-1,7) \rightarrow A'(-1,-7)$

$B(6,5) \rightarrow B'(6,-5)$

$C(-2,2) \rightarrow C'(-2,-2)$

Therefore, the only reflection rule on the coordinate plane that verifies the triangle are congruent when reflected over x-axis is, $(x,y) \rightarrow (x, -y)$
