-4h - 6 = 22 what does h equal

daser333 [38]

-4h -6 = 22
To solve this, we need to get -4h by itself and then simplify.
-4h -6 = 22
Add 6 to both sides.
-4h = 28
Divide both sides by -4.
h = -7.

I hope this helps!

What is the amplitude, period, and phase shift of f(x) = −3 cos(4x + π) + 6?

hammer [34]

This is in the form of $\sf acos(bx-c)+d$ .

Amplitude is equal to $\sf |a|$
Period is equal to $\sf\dfrac{2\pi}{|b|}$
Phase Shift is equal to $\sf\dfrac{c}{b}$

Plug in the values:

Amplitude:
$\sf |a|\rightarrow |-3|\rightarrow\boxed{\sf 3}$

Period:
$\sf\dfrac{2\pi}{|4|}\rightarrow\dfrac{2\pi}{4}\rightarrow\boxed{\sf\dfrac{\pi}{2}}$

Phase Shift:
$\sf\dfrac{c}{b}\rightarrow\boxed{\sf -\dfrac{\pi}{4}}$

Find the value of b. Round your answer to the nearest tenth.

marissa [1.9K]

Answer:

Side CA = 7.8

Step-by-step explanation:

Given:

Acute angled $\triangle ABC$ .

$\angle B =40^\circ$

AB = 10

BC = 12

We can use cosine rule here to find the side AC = b

Formula for cosine rule:

$cos B = \dfrac{a^{2}+c^{2}-b^{2}}{2ac}$

Where

a is the side opposite to $\angle A$

b is the side opposite to $\angle B$

c is the side opposite to $\angle C$

$cos 40 = \dfrac{12^{2}+10^{2}-b^{2}}{2\times 12\times 10}\\\Rightarrow cos 40 = \dfrac{144+100-b^{2}}{240}\\\Rightarrow 0.77 = \dfrac{244-b^{2}}{240}\\\Rightarrow 244-b^{2} = 0.77 \times 240\\\Rightarrow 244-b^{2} = 183.85\\\Rightarrow 244-183.85 = b^{2}\\\Rightarrow b^2 = 60.15\\\Rightarrow b = 7.76$

To the nearest tenth b = 7.8
