Answer:

Step-by-step explanation:

Base area = πr² = 6²π = 36π in²

Circumference = 2πr = 12π in

Lateral area = 2πrh = 144π in²

Total surface area = 2×36π + 144π

= 216π in²

Base area = πr² = π3.25² = 10.5625π in²

Circumference = 2πr = 6.5π in

Lateral area = 2πrh = 6.5π×6.2 = 40.3π in²

Total surface area = 2×10.5625π + 40.3π = 61.425π in²

The sum of the roots of 3x 2 + 11x - 4 = 0 is -11/3 -4/3 11/3 4/3

givi [52]

Answer:

The correct option is 1.

Step-by-step explanation:

If a quadratic equation is defined as

$ax^2+bx+c=0$ .... (1)

Then the sum of the roots is -b/a and the product of roots is c/a.

The given equation is

$3x^2+11x-4=0$ ... (2)

From (1) and (2) we get a=3, b=11 and c=-4.

The sum of roots is

$\frac{-b}{a}=-\frac{11}{3}$

The sum of roots is $-\frac{11}{3}$ .

Therefore the correct option is 1.

Use the distributive property to solve the equation 2(m + 2) = 22. Describe what it means to distribute the 2 to each term insid

Mumz [18]

Answer:

m = 9

It means that you are multiplying each of the values inside the parentheses by 2.

Step-by-step explanation:

2(m + 2) = 22

2m + 4 = 22

2m + 4 - 4 = 22 - 4

2m = 18 -Divide both sides by 2

m = 9

PLEASE HELP!! what is the horizontal asymptote of f(x)=2/3^x? Is it on the x-axis or the y-axis?

anygoal [31]

Hey there! :)

Answer:

y = 0, also known as the x-axis.

Step-by-step explanation:

The equation $f(x) = \frac{2}{3} ^{x}$ is an exponential function.

There is an asymptote at y = 0, or the x-axis because:

$\frac{2}{3} ^{x}\neq 0$

An exponential function, unless containing a vertical shift, can never cross the x-axis resulting in an asymptote at y = 0.
