Answer:

-10

Step-by-step explanation:

You want to know the rate of descent in feet per second represented by a descent of 40 feet in 4 seconds.

The rate is the amount divided by the time:

-40 ft/(4 s) = -10 ft/s

The relevant integer is -10.

Which of the following expressions represents the least common multiple of 15, 18, and 25?

Virty [35]

Answer:

$(2)(3^2)(5^2)$

Step-by-step explanation:

we know that

The Least Common Multiple (LCM) of a group of numbers is the smallest number that is a multiple of all the numbers.

we have

15,18 and 25

Decompose the numbers in prime factors

$15=(3)(5)$

$18=(2)(3^2)$

$25=(5^2)$

Multiply common and uncommon numbers with their greatest exponent

The LCM is equal to

$LCM=(2)(3^2)(5^2)$

$LCM=450$

HELP PLEASE ASAP!!!!

vodomira [7]

Answer:

I may be wrong, but I learned that the first slot would be "terms". 4:3 would be an example of a ratio so it couldn't be ratio and a difference is subtracting.

The second slot would not be a geometric sequence because it is not correctly placed on the number line.

Therefore, the answers would be "terms" and "is not"

F(x) = x2 + 3x + 2 is shifted 2 units left. The result is g(x). What is g(x)?

Misha Larkins [42]

Answer:

$g(x) = x^2+7x+12$

Step-by-step explanation:

If we are given a function f and we want to shift it a units horizontally, the resulting function will be f(x - a), where a positive a is a shift rightwards and a negative a is a shift leftwards.

We have the function:

$f(x)=x^2+3x+2$

And we want to shift it two units to the left.

Since we want to shift it two units to the left, a = -2. Therefore, our new function, let's call it g, must be f(x - (-2)) or f(x + 2). Substitute:

$g(x) = f(x+2)=(x+2)^2+3(x+2)+2$

Simplify. Expand:

$g(x) = (x^2+4x+4)+(3x+6)+2$

Combine like terms. Hence:

$g(x) = x^2+7x+12$
