An airplane heading due east has a velocity of 210 miles per hour. A wind is blowing from the north at 38 miles per hour. What i

Nimfa-mama [501]

Answer:

The resultant velocity of the airplane is 213.41 m/s.

Step-by-step explanation:

Given that,

Velocity of an airplane in east direction, $v_1=210\ mph$

Velocity of wind from the north, $v_2=38\ mph$

Let east lies in the direction of the positive x-axis and north in the direction of the positive y-axis.

We need to find the resultant velocity of the airplane. Let v is the resultant velocity. It can be calculated as :

$v=\sqrt{v_1^2+v_2^2}$

$v=\sqrt{(210)^2+(38)^2}$

v = 213.41 m/s

So, the resultant velocity of the airplane is 213.41 m/s. Hence, this is the required solution.

By what percent will a fraction change if its numerator is decreased by 20% and its denominator is decreased by 60%?

Vedmedyk [2.9K]

Answer:

The fraction will increase by 100%

Step-by-step explanation:

Say the fraction is x/y. The question is telling us to decrease x by 20% (i.e. 0.8x) and to decrease y by 60% (i.e. 0.4y):

$= \frac{0.8x}{0.4y}\\= 2 (\frac {x}{y})$

You can see that by applying these changes, the new fraction is actually double the old fraction (i.e. will increase by 100%).

BRAINLIEST FOR AN ACTUAL ANSWER

Andreyy89

Answer:

The correct pair of functions is the third one: h(x)=(x−24)^2 and g(x)=x2

Step-by-step explanation:

Example: If we have q(x) = x^2 and its graph, moving the vertex of this graph 24 units to the right results in r(x) = (x - 24)^2.

The correct pair of functions is the third one: h(x)=(x−24)^2 and g(x)=x2

Note: the fourth pair is incorrect, because the " + " sign moves the graph of x^2 24 units to the left.
