Step-by-step explanation:

Factor 10x^2 - 5x:

Then:  10x^2 - 5x = 5x(2x - 1), since 5x is common to the two given terms

Answer:

[tex]10x^{2} -5x[/tex] in factored form would be [tex]5x(2x-1)[/tex]

Step-by-step explanation:

If we look at all of the terms in this binomial, we can see that they both have 5x in common.  We can now factor 5x out of the equation to get our answer.

To do this, we must divide both terms by 5x.

[tex]10x^2[/tex] divided by [tex]5x[/tex] is [tex]2x[/tex], and [tex]-5x[/tex] divided by [tex]5x[/tex] is [tex]-1[/tex].

So, our final answer is [tex]5x(2x-1)[/tex].

If g(x)=4x^(2)-16 were shifted 7 units to the right and 3 down, what would the new equation be?

Answers

The equation of the transformed function is h(x) =  4(x - 7)² - 19 option (C) is correct.

What is a function?

It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.

We have a function:

g(x) =  4x² - 16

The above function shifted 7 units to the right and 3 down.

Applying transformation:

x → (x - 7)

G(x) =  4(x - 7)² - 16

G(x) → G(x) - 3

h(x) =  4(x - 7)² - 16 - 3

h(x) =  4(x - 7)² - 19

Thus, the equation of the transformed function is h(x) =  4(x - 7)² - 19 option (C) is correct.

Answers

Answer:

Ф = 2pi/3 , 4pi/3

Step-by-step explanation:

1 + cos Ф = 1/2

Subtract 1 from each side

1 + cos Ф -1 = 1/2-1

cos Ф = -1/2

Take the inverse cos of each side

cos^-1 ( cos Ф )= cos^-1(-1/2)

There are two solutions for the inverse cos of (-1/2), 2pi/3  and 4pi/3

 Ф = 2pi/3 +2 npi

First function; Initial value = 250; Decay; Decay rate = 11%

How to solve exponential decay functions?

1) The first function is;

y = 250 (initial value)

Decay because 0.89 < 1

Thus;

Decay rate: (1 - 0.89) * 100 = 11%

2) The second function is;

250 = 40(1.11)^(x)

What value is missing from the table?
A. 4.5
B. 5.5
C. 5
D. 4

Answers

Answer:

D. 4

Step-by-step explanation:

The faster you go, the faster you get home (theoretically anyway) and vice versa. So if your speed is doubled, it'll take half the time to get home. But if your speed gets halved, it'll also take double the time to get home.

So, if at 60 mph it takes 1 hour to get home, then if your speed is divided by four to 15 mph, you need to multiply the time by the same number and thus the answer is 4.
