Answer:

550 N

Step-by-step explanation:

We can solve the problem by using Newton's second law:

[tex]F=ma[/tex]

F is the force required to accelerate the car

m is the mass of the car

a is the acceleration of the car

In this problem, the mass is m=1100 kg, while the acceleration is a=0.5 m/s^2, therefore the force required to accelerate the car is

[tex]F=ma=(1100kg)(0.5m/s^{2} )=550N[/tex]

Hope this helps!

Answer:5

Step-by-step explanation:

a2+b2=c2

a2+12squared=13 squared

169-144=a2

a2=25, now that we have 25 we have to find the square root which is 5.

Answer:

a

Step-by-step explanation:

divide whole equation by 4m

m^3 + 9m^2 + 24m+20

and then factor out (m+5)

4m(m+5)(m^2+4m+4)

end with 4m(m+5)(m+2)(m+2)

or 4m(m+5)(m+2)^2

or (m^2+5m)(2m+4)^2

Answer:

CI = ( 0, 042 ;  0,079 )

Step-by-step explanation:

If from 884 , 831  disks were OK  then  884  - 831  = 53 were defective

x  =  53

p = 53/884    p  = 0,0599     or p = 5,99 %   p ≈ 6 %

and q =  1  - 0,06       q = 0,94

p*n  and q*n   are big enough

For CI 98 %  significance level is α = 2 %   α/2 = 0,01

z(score) for α/2 = 0,01 is

z(c) ≈ 2,324

CI  =  p ±  z(c) *√p*q/n

√p*q/n   =  √ ( 0,94*0,06)/884

√p*q/n   =  √ 0,0564/884

√p*q/n   =  0,00799

CI  =  ( 0,06  ±  2,324*0,00799)

CI  =  ( 0,06  - 0,0185 ; 0,06 +  0,0185 )

CI = ( 0, 042 ;  0,079 )

Answer: The piano has 222 strings, because 37×6=222.

Step-by-step explanation:

Since we are informed that Leslie tuned a guitar with 6 strings today and that she then tuned a piano with 37 times as many strings.

This simply means that we have to multiply 37 by 6 strings to get the value of the strings of the piano that she tuned. This will be:

= 6 × 37

= 222 strings.

Leslie tuned 222 strings.

Therefore, the piano has 222 strings, because 37×6=222.

Answer:

7.48m (3s.f.)

Step-by-step explanation:

Let the missing side be x m.

Applying Pythagoras' Theorem,

x² +5²= 9²

x² +25= 81

x²= 81 -25 (-25 on both sides)

x²= 56

[tex]x = \sqrt{56} [/tex]

[tex]x = 2 \sqrt{14} [/tex]

x= 7.48 (3 s.f.)

∴ The missing side is 7.48 m (3s.f.)

Answer:

Answer:

The line is a vertical line, which does not have a slope.

Step-by-step explanation:

Slope of a line:

Suppose we are given two points in the format (x,y) of a line. The slope is given by the change in y divided by the change in x.

(6,6) and (6, -7).

Change in y: -7 - 6 = -13

Change in x: 6 - 6 = 0

Slope is a division by 0, which means that the line is a vertical line, which does not have a slope.

Answer: x = -20

Step-by-step explanation:

Question: If -x = 20, then x = ?

Multiply both sides of the equation by -1

(-1)(-x) = (-1)(20)

Simplify (remember that multiplying two negative numbers equals a positive number)

x = -20

Answer:

The ratio of approved and disapproved people in its simplest form is 3:1.

Step-by-step explanation:

Since 81 people passed and 27 failed their Functional Skills Level 2 exams, to write this as a ratio in its simplest form, the common greatest divisor of both numbers must be obtained:

27 is divisible by 1, 3, 9 and 27

81 is divisible by 1, 3, 9, 27 and 81

Therefore, the common greatest divisor of both numbers is 27. So, since 27/27 is equal to 1, and 81/27 is equal to 3, the ratio of approved and disapproved people in its simplest form is 3 :1.

The ratio in its simplest form is 1 : 3.

Ratio expresses the relationship between two numbers. It is the frequency with which a number is contained in another number. The sign used to represent ratio is ':'.

In order to express the given number of people that passed and failed the exam, we have to divide both numbers by the highest common factor until both numbers cannot be divided further to yield a whole number.

Common factor of 27 and 81 = 1, 3, 9, 27

Highest common factor = 27

Expressing in the simplest form = 1 : 3

Step-by-step explanation:

The equation of a circle centred at the origin is

x² + y² = r² ( r is the radius )

x² + y² = 16 ← is the equation of a circle

centre (0, 0 ) and r = [tex]\sqrt{16}[/tex] = 4

The circle therefore intercepts the x- axis at (4, 0 ) and (4, 0 )

and intercepts the y- axis at (0, - 4 ) and (0, 4 )

Domain is - 4 ≤ x ≤ 4

range is - 4 ≤ y ≤ 4

x- intercepts are x = - 4, x = 4

y- intercepts are - 4, 4

Answer:

The equation of a circle centred at the origin is

x² + y² = r² ( r is the radius )

x² + y² = 16 ← is the equation of a circle

centre (0, 0 ) and r = \sqrt{16}16 = 4

The circle therefore intercepts the x- axis at (4, 0 ) and (4, 0 )

and intercepts the y- axis at (0, - 4 ) and (0, 4 )
