Area of a Circle
Cloud [144]

Answer:

The diameter of the pond is 38 m.

The radius of the pond is 19 m.

The area of the pond is 361 m^2.

Step-by-step explanation:

We know that the circumference C of a circle is equal to

C=\pi D

In this case, C is equal to 120 m.

The diameter is then:

D=C/\pi=120/3.14=38.21\approx 38

Rounded to the nearest whole number, the diameter is D=38 metres.

The radius is equal to half the diameter, so the radius of this pond is R=19 metres.

R=D/2=38/2=19

The area can be calculated from the radius as:

A=r^2=19^2=361

The area is 361 m^2

What is (f - g)(x)?<br>f(x) = 5x<br>g(x) = 3x2 - 8x​
erma4kov [3.2K]

Answer:

(5x)-(3x^2-8x)=-3x^2+13x

Step-by-step explanation:

(f-g)(x)=f(x)-g(x)

Using this, we can subtract and find the answer.

(5x)-(3x^2-8x)=-3x^2+13x

An exam worth 145 points contains 50 questions. The number of two-point questions is equal to 50 minus the number of five-point
abruzzese [7]

Answer:

Therefore there are 35 number of 2-point questions and 15 number of 5-point questions.

Step-by-step explanation:

i) let the number of 2 point question is x.

ii) let the number of 5 point questions be y

iii) total number of questions is 50

iv) therefore x + y = 50

v) it is also given that 2x + 5y = 145

vi) solving for the two equations found in iv) and v). Multiplying iv) by 2 we get

    2x + 2y = 100

vii) subtracting equation vi) from equation v) we get 3y = 45.

viii) Therefore y = 15.

ix) using the value in viii) and substituting in iv) we get x + 15 = 50.

    Therefore x = 50 - 15  = 35

x) Therefore there are 35 number of 2-point questions and 15 number of 5-point questions.

All of the given options are in slope intercept form.

Slope intercept form is y=mx+b

This is where m is the slope fo the line and b is the y intercept

That said, we can simply plug the given values into the form.

y=(2/3)x+(-2)

Simplify

y=2/3x-2
