Most likely centimetres, because metres are too big and millimetres are too small :)

Answer:

centimeter.

Step-by-step explanation:

Tennis balls are the balls which are usually designed top play the sport of tennis. They are usually of fluorescent yellow in color but it can be of any color.

The certain criteria is set for tennis balls for their weight, size, bounce and deformation and the regulation play approved this criteria. The official diameter of the tennis ball is 6.54–6.86 cm which set by the International Tennis Federation. And the mass of these tennis balls ranges from 56 g- 59.6 g.

Therefore, the radius of tennis balls is measured in centimeters.

Find the area of the shaded region.

earnstyle [38]

There are four parts of a circle, so you have to find out the area of the circle:-

10 cm=Radius

$10^{2}$ =100

$\pi$ =3.14

3.14*100=314 $cm^{2}$

Now, find the area of the square box:-

Since half the side of the square is 10 cm, the total length of one side is 2*10 which is 20 cm.

Area=S*S

=20*20=400 $cm^{2}$

Now subtract the area of the box from the area of the square:-

400-314= 86 $cm^{2}$

That is the area of the shaded part.

Happy to help you!

For the graph x = -42 find the slope of a line that is perpendicular to it and the slope of a line parallel to it. Explain your

tamaranim1 [39]

X - 42 is a straight vertical line passing through -42 on the x-axis ( point -42,0)
so the slope is infinite .
Another line with same slope and parallel to it would be x = 36.

A horizontal like with slope 0 is perpendicular to it It would have equation y any number so y = 6 would be an example.

Answer:

V(t) = 25(1.07^t)
V(t) = 40(1.05^t)

Step-by-step explanation:

Put the given numbers into the given formula. It can be simplified a little bit.

Formula:

V(t) = P(1 + r)^t

Coin A

P = 25, r = .07

V(t) = 25(1.07^t)

Coin B

P = 40, r = 0.05

V(t) = 40(1.05^t)

Manny has $650 in his savings

Bumek [7]

Answer:

Interest Manny earns after 2 years is $52

Step-by-step explanation:

Amount deposited = $650

Simple annual interest rate = 4%

To find: Interest after 2 years

We know that the formula to calculate the interest amount is

Simple interest (S.I.) = $\frac{Prt}{100}$

where,

P is the initial amount deposited

r is the rate of simple interest in percentage

t is the time in years for which interest is to be calculated

Substituting the known values in the formula, we get

S.I = $\frac{650 x 4 x 2}{100}$

= 52

Hence the interest Manny earns after 2 years is $52

Verify x + 1⁄2 is a factor of P(x)= x2 + x -2

kumpel [21]

Answer:

Put p(x)=0.

Step-by-step explanation:

2x-1=0 will give x=1/2. This means, If x=1/2 is given to the polynomial p(x), it will give a zero. P(1/2)=0.
