Answer:

AB = 8.39 inches

AC = 13.1 inches

(corrected to 3 significant figures.)

Step-by-step explanation:

In a right triangle, AB is the opposite side; BC is the adjacent side, and AC is the hypotenuse side.

since tanθ = opposite / adjacent,

we can use this to find side AB.

tan40° = AB / 10

AB = 8.39 in. (corrected to 3 significant figures.)

since cosθ = adjacent / hypotenuse

we can use this to find AC.

cos40° = 10 / AC

AC = 13.1 in. (corrected to 3 significant figures.)

Given f(x)=-3x+3solve for x when f(x)=6

natali 33 [55]

Answer:

x = -1

Step-by-step explanation:

Given: $f(x) = - 3x + 3$

Solve for x, When: $f(x) = 6$

Step by step:

$- 3x + 3 = 6$

$- 3x = 6 - 3$

$- 3x = 3$

$x = 3 \div - 3$

$\boxed{\green{x = - 1}}$

Please help! I'm getting timed.

Molodets [167]

Hi there! The answer is A.

$t = 2(s + 2)$
To get a proper idea of the type of function this formula represents we work out the parenthesis.

Working out the parenthesis can for instance be done using rainbow technique.
$t = 2s + 4$

We can now see sinilarities between this function an the general function of a line in slope intercept form
$y = mx + n$

The function t therefore describes a line with slope 2 and y-intercept 4. Therefore the answer is A.
