I need help with this problem! I'll give brainlist! ​
aliya0001 [1]

Step-by-step explanation:

use CAH method (Cos angle = adjacent/hypotenuse)

Given adjacent = 5

Hypotenuse = 12,

\cos(x) =  \frac{adjacent}{hypotenuse}  \\  \cos(x)  =  \frac{5}{12}  \\ x =  {cos}^{ - 1} ( \frac{5}{12} ) \\  = 65.4deg(nearest \: tenth)

P(x) = 3x + 4<br>q(x) = 2x2<br>Find q(P(x))​
max2010maxim [7]

Answer:

Step-by-step explanation:

If we are to find q(p(x)), we are to start at the innermost part of the problem which is p(x). Take the function p(x) and fill it into q(x) every place you see an x:

2(3x+4)^2 is the composition of p into q.  Now all we have left to do is simplify.

(3x+4)^2=9x^2+24x+16

Then we have to finally multiply in the 2 to get:

18x^2+48x+32

HELP GEOMETRY!!!!!! The newest feature at the Great Park is the big orange balloon. The volume of this perfectly spherical ballo
WITCHER [35]

Answer: 8.3 ft

Step-by-step explanation:

Here, The volume of this perfectly spherical balloon is approximately 2361.7 cubic feet.

Since, the volume of a sphere, V= \frac{4}{3} \pi r^3

Where r is the radius of the sphere.

Here V= 2361.7 cubic feet

Therefore, 2361.7=\frac{4}{3} \pi r^3

⇒ r^3= \frac{21\times 2361.7}{88}

⇒r= 563.5875^{1/3}=8.2601344693≈8.3 feet

Thus, the radius of the sphere = 8.3 feet

Solve (t - 3)2 = 6. The arrow is at a height of 48 ft after approximately _ s<br>and after _s​
Slav-nsk [51]

Answer:

The arrow is at a height of 48 ft after approximately <u>0.55</u> s  and after <u>5.45</u> s​

Step-by-step explanation:

The following information is missing:

<em>The height of an arrow shot upward can be given by the formula s = v0*t - 16*t², where v0 is the initial velocity and t is time.How long does it take for the arrow to reach a height of 48 ft if it has an initial velocity of 96 ft/s? </em>

If the arrow is at a height of 48 ft and its initial velocity is 96 ft/s, then:

48 = 96*t - 16*t²

16*t² - 96*t + 48 = 0

16*(t² - 6*t + 3) = 0

t² - 6*t + 3 = 0

t² - 6*t + 3 + 6 = 0 + 6

t² - 6*t + 9 = 6

(t - 3)² = 6

t - 3 = √6

t - 3 = 2.45; t = 2.45 + 3; t = 5.45

or

t - 3 = -2.45; t = -2.45 + 3; t = 0.55
