Answer:

The bird will have traveled 403 meters in 13 seconds if it maintained a speed of 31 m/sec

Explanation:

The equation that relates velocity, distance and time is:

$velocity = \frac{distance}{time}$

This means that:

distance = velocity * time

In the given, we have:

velocity = 31 m/sec

time = 13 sec

Substitute with the givens in the above equation and solve for the distance as follows:

distance = velocity * time

distance = 31 * 13

distance = 403 meters

Hope this helps :)

Find the co-ordinate of the image of the point A (3, -2) when it is reflected on the line x=0 and then rotated about origin thro

Luba_88 [7]

Answer:

Step-by-step explanation:

Rotations are easy when its multiples of 90 degrees; 90,180,270,360. Treat them like they’re a complex number like [x+yi]*i=[-y,xi] so rotating by 90 degrees and 180 is i squared [-1]! So [-3,2] rot90 is [-2,-3].

Reflection about the y=x line is change places. [x.y]=[y,x].

So [-2.-3] reflected about the y=x line is [-2.-3]=[-3.-2],

Compile a list of these transform is best practice technique in this area.

Fred wants to find 48+34 using compensation.He says you can take 2 from 34 and give it to 48 to make 50.What is the sum?Explain

Montano1993 [528]

It is easier to add 50 to a number than 48 because 50 has a zero in it which makes an addition simpler.

48 + 34 = borrow 2 from 34 and add to 48

= 50 + 32 50 + 32 is 82

= 82

Determine the length of the leg of a 45o – 45o – 90o triangle with a hypotenuse length of 15 inches. ( ANSWER NEEDS TO BE IN RED

SIZIF [17.4K]

Answer:

The lenghts of both legs: $\frac{15\sqrt{2}}{2}\ inches$

Step-by-step explanation:

By definition, when a triangle has angles that measures 45°, 45° and 90°, its legs are congruent.

Then, knowing the lenght of the hypotenuse, we can find the lenght (in inches) of any leg of the given triangle by applying the Trigonometric Identity $sin\alpha=\frac{opposite}{hypotenuse}$ :

$sin(45\°)=\frac{leg}{15}\\\\leg=\frac{15}{\sqrt{2}}$

Finally, simplifying, we get:

$leg=\frac{15(\sqrt{2})}{(\sqrt{2})(\sqrt{2})}=\frac{15\sqrt{2}}{2}$
