the first question...the answer is 10

see;x is our unknown number

so;27-2=25

x + 15=25

x = 25-15

x =10

10 + 15 = 25

25 + 2 = 27

Hello :
(gog)(-2) = g(g(-2))
but g(-2) = (-2)²-4(-2)-5 =4+8-5=7
(gog)(-2) = g(g(-2)) =g(7) = 7²-4(7)-5 =49-33 =16

You want to calculate the displacement of an object thrown over a bridge. Using -10 m/s^2 for acceleration due to gravity, what

MrRissso [65]

Answer

The total displacement of the object is 320 m

Solution-

From the formulas of mechanics,

$s=ut+\frac{1}{2}at^{2}$

Where,

s = displacement

u = initial velocity = 0 ( ∵ As the body was in rest in the beginning )

t = time taken = 8 s

a = acceleration = -10 m/s² ( ∵ -ve is because of the downward motion)

Putting all the values,

$s= 0 \times 8 + \frac{1}{2}(-10)8^{2} = -320 \ m$ ( ∵ -ve displacement means it is in downwards)

1. A chord is 22 cm long. It is 60 cm from the center of the circle.

mezya [45]

Answer:

Radius, r = 61 cm

Step-by-step explanation:

According to the attached figure, we have,

Length of chord, AB = 22 cm

Such that, AP = PB = 11 cm

OP = 60 cm

It is required to find the radius of the circle. We know that radius of a circle is perpendicular to chord. So, APO forms a right angled triangle. Using Pythagoras theorem to find the radius of circle. Let it is r. So,

$r^2=60^2+11^2\\\\r=61\ cm$

So, the radius of the circle is 61 cm.
