Answer 1

Answer:

Area of prism = base area × altitude

1. (2x²-10)(x+4)

= 3x³-2x - 40

2. Base area = 2πr

Volume = (2πr)(r²+ 5r)

=2πr³ + 10πr²

3. Base area=½(6)(x-4)(x+3)=3(x-4)(x+3)

Volume= 3(x-4)(x+3)(⅓)

=(x-4)(x+3)= x² - x -12

4. Base circumference= 10π

Base radius = 10π/(2π) = 5

Base area = πr² = 25π

Volume = 25π(3x²-2x)

=125πx²-50πx

5. Volume = 3π√50

=15π√2

6. Base diameter = 16

Base radius = 16/2 = 8

Base area = 2πr = 16π

Volume = 16π(23a²)

=368πa²

A sequence is defined recursively using the equation f(n + 1) = f(n) – 8. If f(1) = 100, what is f(6)?

Answers

$f_(2)$ = 100 - 8 = 92
$f_(3)$ = 92 - 8 = 84
$f_(4)$ = 84 - 8 = 76
$f_(5)$ = 76 - 8 = 68
$f_(6)$ = 68 - 8 = 60

$f_(6)$ = 60

What is the excluded value?a/b-2

1. a=0
2. b=2
3. b=-2
4. none of the above

Answers

Answer: The correct option is (2) $b=2.$

Step-by-step explanation: We are given to find the exclude value for the following algebraic expression:

$E=(a)/(b-2)~~~~~~~~~~~~~~~~~~~~~~(i)$

We know that

for a rational expression, we must exclude those values for which the denominator of the fraction becomes zero.

So, in equation (i), the excluded value will be given by

$b-2=0\n\n\Rightarrow b=2.$

Thus, the required excluded value is $b=2.$

Option (2) is CORRECT.

b - 2 = 0 since you cannot divide by 0
b = 2 solve for b. this is where the function is undefined

The reciprocal of of 1 over 5

Answers

The reciprocal of 1/5 is: 5/1 or just 5.

To get the reciprocal of a fraction, it basically just means to flip the numbers. If you're dealing with a whole number (such as 5 in this case), you would divide 1 by the number, making it 1/5.

connor is using a computer program to graph the function H(n)= -13n - 421. He wants to see the intercepts. Which minimum values should he use to set up the viewing window?

Answers

I can't see any slick, easy way to tell without finding
the intercepts, so here goes:

The y-intercept is the value of   H(n) when 'n' is zero.

H(0) = -13(0) - 421

      = - 421 .

The n-intercept is the value of 'n' when H(n) is zero.

0 = -13n - 421

Add 13n to each side: 13n = - 421

Divide each side by 13 :    n = - 421/13 = - 32.4...

Connor should set up the viewing window so that 'n' displays
at least down to - 33 , and H(n) displays at least down to - 421 .

At the corner store, Nico bought 5 pencils for $0.10 each and 3 pens for $0.50 each. He used t to represent the sales tax, in dollars, that he also paid. He paid a total of $2.12, including tax. Nico wrote this equation to represent what he paid. What errors, if any, did he make? 5(0.10) + 3(0.50) - t = 2.12
