Answer:

a=5.43\ m/s^2

Step-by-step explanation:

Given that,

Initial speed of a vehicle, u = 25 km/hr = 6.95 m/s

Final speed of a vehicle, v = 1200 km/hr = 333.34 m/s

Time, t = 60 s

We need to find the acceleration of the vehicle. It is equal to the rate of change of velocity. It can be given by :

a=\dfrac{v-u}{t}\\\\a=\dfrac{333.34 -6.95 }{60}\\\\a=5.43\ m/s^2

So, the acceleration of the vehicle is 5.43\ m/s^2.

Marcella would not be able to win the competition because her kite string (159.75 feet) is less than 162 feet.

<h3>What is an equation?</h3>

An equation is an expression that shows the relationship between two or more numbers and variables.

Trigonometric ratio is used to show the relationship between the sides and angles of a right angled triangle.

Let l represent the length of the string, hence:

sin(28) = 75/l

l = 159.75 feet

Marcella would not be able to win the competition because her kite string (159.75 feet) is less than 162 feet.

Find the equation of the line that is perpendicular to y = - 1/3 x + 2 and passes though the point (-5,2)
elena55 [62]

Answer:

y - 2 = 3(x + 5)

Step-by-step explanation:

The given equation has slope -1/3.  Any line perpendicular to the given line has a slope which is the negative reciprocal of -1/3, which comes out to +3.

Use the point-slope formula y - k = m(x - h):

y - 2 = 3(x + 5)

An angle is 21 degree more than twice its complement find it
jekas [21]

Answer: 67°

Step-by-step explanation:

Complementary angle refers to the angle that when added together will be equal to 90°.

Let the measurement of the angle's complement be x.

Therefore, the angles are x and 2x + 21. Since it's a complementary angle, therefore,

x + 2x + 21 = 90

3x + 21 = 90

3x = 90 - 21

3x = 69

x = 69°/3

x = 23°

Therefore, the angle will be:

= 2x + 21

= 2(23°) + 21°

= 46° + 21°

= 67°

The angle is 67°.
