Find the indicated values, where

Rom4ik [11]

Answer:

option (b) is correct.

The value of $g(f(3)-2f(1))$ is 0.

Step-by-step explanation:

Given: $g(t)=t^2-t$ and $f(x)=1+x$

We have to find the value of $g(f(3)-2f(1))$

Consider the given function $f(x)=1+x$

First evaluate value of function f(x) at x = 3 and 1 then substitute it in $g(f(3)-2f(1))$ .

f(3) = 1 + 3 = 4

f(1) = 1 + 1 = 2

Substitute, we get

$g(f(3)-2f(1))=g(4-2(2))$

Solving further , we get,

$g(f(3)-2f(1))=g(4-4)=g(0)$

Now evaluate $g(t)=t^2-t$ at t = 0 , we get,

$g(0)=0^2-0=0-0=0$

Thus, value of $g(f(3)-2f(1))$ is 0.

Thus, option (b) is correct.

Answer:

yint -= (0,100) slope = -5 2/3

Step-by-step explanation:

yint is (0,100) because thats where it hits the y axis

slope equation is (y1-y2)/(x1-x2), just pick out any two points to do this with

(83-66)/(3-6)

Question six about significant figures, please help!

belka [17]

rules to find :- 1 All non zeroes number are significant

2 if zero proceeding the decimal point also work as non zero figure

3 zero are following the decimal point and proceeding the first non zero digit

4 Zero in between 2 non zero digits are also significant

5 if 1 zero follow the decimal point

790 :- 2 significant figures

0.0391 :- 3 significant figures ( follow 3 rule)

81.05 :- 4 significant figures ( rule 4)

0.000001 :- 1 significant figure

8546 :- 4 significant figures

79.0 :- 3 significant ( rule 5)

A triangle has sides that measure 4 units, 6 units, and 7.21 units. What is the area of a circle with a circumference that equal

Rina8888 [55]

Step-by-step explanation:

Given that,

Sides of a triangle is 4 units, 6 units, and 7.21 units.

We need to find the area of a circle with a circumference that equals the perimeter of the triangle.

Perimeter of triangle = circumference of circle

4+6+7.21=2πr, r is the radius of circle

r = 2.73 units

Area of circle,

$A=\pi r^2\\\\A=3.14\times (2.73)^2\\\\A=23.402\ \text{units}^2$

A = 24 sq units

So, the area of the circle is 24 square units.
