Select the formula for the xth term of the sequence.
3, 11, 19,

Answers

Answer 1

Answer:

8n - 15

Step-by-step explanation:

for finding the nth term we need to figure out the difference between the numbers:

3,11,19 = difference of 8

multiples of 8:

8,16,24,32,40...

the nth term would be 8n - 5 because in order to get to 3 from 8, we minus 5

A hot air balloon went from an elevation of 5,717 feet to an elevation of 3,388
feet in 34 minutes. What was its rate of descent?
The rate of the descent was
feet per minute.

Answers

Answer:

68.5 feet per minute

Step-by-step explanation:

rate of descent = feet / minute

First you need to find how many feet it has descended:

beginning altitude- ending altitude = total feet descended

5717 feet - 3388 feet = 2329 feet

To figure out the rate of decent we will divide

2329 feet / 34 minutes = 68.5 feet per minute

The hot air ballon descended 68.5 feet per minute for 34 minutes.

How many roots does y=3x^2+8 have?

Answers

Answer:

This quadratic has two unequal, imaginary roots.

Step-by-step explanation:

y = 3x^2 + 8 is a quadratic function, and (like all quadratics) it has two roots.  In this case they happen to be different (unequal), as well as imaginary.

Setting y = 3x^2 + 8 = 0, we get:

3x^2 = -8, or

x^2 = -8/3

Taking the square root of both sides, we get

x = ±i√(8/3) (2 imaginary roots)

y= -4

so you plus y in for the y=2x+2 equation where you get x=-3

[tex]\huge\text{Hey there!}[/tex]

[tex]\large\text{If y = -4 then SUBSTITUTE it into the EQUATION}[/tex]

[tex]\large\text{-4 = 2x + 2}[/tex]

How would I find the values of x, y and z?

Answers

Answer:

x = 3.38

y = 9.24

z = 8

Step-by-step explanation:

first: solve for the vertical length

8√2² = 2z²

128 = 2z²

z² = 64

z = 8

vertical height = 8 also because z is one side of a square

tan 60 = z/a = 8/a

a = 4.62

x = 8 - 4.62 = 3.38

sin 60 = z/y = 8/y

y = 9.24

Which would be the first step for solving the equation x + 2 = 18?
A. add - 2 to both sides of the equation
B. add 18 to both sides of the equation
c.
divide both sides of the equation by
7
16
D
multiply both sides of the equation by
7

Answers

The first step for solving this equation would be adding -2 to both sides of the equation.

Answer:

A. Add -2 to both sides

Step-by-step explanation:

The reason you need to add -2 to both sides is because if you add -2 to -2 it cancels out and you are left with x=18. But you need to add -2 to 18 too because them the equation won't be equal anymore.

Given:

Base of the triangle = 24

Height of the triangle = 10

Another side of the triangle = 26

To find:

The area of the expression of the area of the triangle.

Solution:

We know that, the area of a triangle is

[tex]Area=\dfrac{1}{2}\times base\times height[/tex]

Putting base = 24 and height = 10, we get

[tex]Area=\dfrac{1}{2}\times 24\times 10[/tex]

It can be written as

[tex]Area=\dfrac{1}{2}\times 10\times 24[/tex]

Therefore, the correct option is A.

1 foot= 12 inches

143/ 12 = 11 11/12

Answer:

D) 11 feet and 11 inches

Step-by-step explanation:

First we know that there is 12 inches in a foot. So let's start with a.

14 inches x 12 inches (one foot) is 168 inches (so it's not this one:)

13 inches x 12 inches is 156 inches (It's not this one either)

12 inches x 12 inches is 144 inches (not this one)

11 inches x 12 inches is 132 inches (so it could be this one, let's add the remaining inches).

132 + 11 inches = 143 inches.

(Notice I didn't add the remaining inches on A, B, or C because the number of inches was already too much. I did on D because the number of inches was below the given number of 143.
