Answer:

26 degrees below zero

Step-by-step explanation:

add the two numbers together and since 12 below zero would be -12 and it drops 14 more it would be -12 - 14 which would lead to -26 because since both are negative its basically adding then putting the negative sign in front.

In this problem, we need to use squaring method.

5² means 5 × 5

5² = 25

12² means 12 × 12

12² = 144

So, simplify these statements:

5² × 12²

25 + 12² (Simplify 5², which means 5 × 5)

25 + 144 (Simplify 12², which means 12 × 12)

We get the answer:

25 + 144 =

Answer:

the answer is $\sqrt{5\\}$ , and - $\sqrt{5\\}$ which is C.

Step-by-step explanation:

well I got that answer by doing this

we have $x^{2}$ = 5

For $x^{2}$ = f (a) the solutions are x = $\sqrt{f(a)\\}$ , - $\sqrt{f(a)\\}$

so in this case the solutions are $\sqrt{5\\}$ , and - $\sqrt{5\\}$

HOPE THIS HELPS :)

Which transformations are needed to change the parent cosine function to y = 3 cosine (10 (x minus pi))?

Alekssandra [29.7K]

Answer:

See Explanation

Step-by-step explanation:

Given

New function: $y = 3 \cos(10 (x -\pi))$

We can assume the parent function to be:

$y = \cos (x)$

The new function can be represented as:

$y = A*\cos((\frac{2\pi}{B})(x-c))$

Where

A = Vertical stretch factor

B = Period

C = Right shift

By comparison:

$y = A*\cos((\frac{2\pi}{B})(x-c))$ to $y = 3 \cos(10 (x -\pi))$

$A = 3$

$c = \pi$

$\frac{2\pi}{B} = 10$

Solve for B

$B = \frac{2\pi}{10}$

$B = \frac{\pi}{5}$

Using the calculated values of $A,\ B\ and\ c.$ This implies that, the following transformations occur on the parent function:

<em>Vertically stretched by </em> $3$ <em />
<em>Horizontally compressed by </em> $\frac{\pi}{5}$ <em />
<em>Right shifted by </em> $\pi$ <em />
