Answer:

x = 44.4°

Step-by-step explanation:

Use SOHCAHTOA.

In this case, use sine trigonometric function formula

\sin(x)  =  \frac{o}{h}

The opposite side of angle is 7.

The hypoteneuse is 10.

So,

\sin(x)  =  \frac{7}{10} \\ x =    \sin ^{ - 1} ( \frac{7}{10} )  \\ x =  {44.427}^{o}  \\ x =  {44.4}^{o}

Answer:

  44.4°

Step-by-step explanation:

The mnemonic SOH CAH TOA reminds you that ...

  Sin = Opposite/Hypotenuse

  sin(x) = 7/10

  x = arcsin(7/10)

  x = 44.4°

Answer:

B. The graph of p is less steep than the graph of q.

Step-by-step explanation:

We can start by looking at each equation's y-intercepts, which are both -3/11, eliminating option A.

Next, we take a look at each equation's slope to see which is larger.

5/8 is 0.625 in decimal form. 8/5 is 1.6 in decimal form.

Therefore, q(x) has the larger slope, meaning the graph of p is less steep than the graph of q. (B.)

Use properties of exponents to write an equivalent expression
Kazeer [188]
First u multiply the numbers in side the parantesis
3³ which is 3•3•3= 9•3=27
next u put the answer back in the parantesis and then multiply using the third power to get the final answer.
(27)³ = ( 27•27•27)= 19683

Which values of P and Q result in an equation with exactly one solution?
Ratling [72]

Answer:

C. Q=−31, P = -2

Step-by-step explanation:

2x+Q = Px−31

A. Q = −2 and P=2

2x+Q=Px−31

2x - 2 =2x - 31

0x = -29

0 ≠ -29 : NO SOLUTION

B.Q=31 and P=2

2x+Q=Px−31

2x + 31 = 2x - 31

0x = -62

0 ≠ -62 : NO SOLUTION

C. Q=−31, P = -2

2x+Q=Px−31

2x - 31 = -2x - 31

4x = 0

 x = 0 : ONE SOLUTION

D. Q=-31 and P=2

2x+Q=Px−31

2x - 31 = 2x - 31

0x = 0

0 = 0: Infinitely many solutions

Answer:

C. Q=−31, P = -2
