Help plz!! The function h(t)=-16t^2+22t+4 models the height (h) of a football t seconds after it is thrown. The question ask to
Black_prince [1.1K]
If you're familiar with the quadratic equation
\frac{ -b \pm \sqrt{b^2-4ac}}{2a}

well, \frac{ -b}{2a} is the x component of the vertex, in your case, the vertex is the highest point

figure out what t is at the highest point, and then substitute that back into the equation in order to determine height

(-2q^4)(-8q^3b^6)<br>help I need to simplify this problem
Montano1993 [528]
Multiply the constants. Multiply the variables according to the rules of exponents.
(-2q^{4})(-8q^{3}b^{6}) = ((-2)(-8))q^{(4+3)}b^{6}\\\\=16q^{7}b^6}

Which is a solution for 4 x + 8 = 3 x + 14?
Liula [17]

Answer:

x=6

Step-by-step explanation:

Step 1:

Subtract 3x from both sides:

4x + 8 - 3x = 3x + 14 - 3x

x + 8 = 14

Step 2:

Subtract 8 from both sides:

x + 8 - 8 = 14 - 8

x = 6

Pls help! evaluate the sine of the real number, pls give exact answers
solong [7]

Answer:

 -\frac{\sqrt2}{2} \\  or exact is −0.70710678...

Step-by-step explanation:

Getting the point!

  1. If we look at the unit circle and we find -\frac{3\pi }{4} we see it is in the 3rd quadrant.
  2. We know that all points in the 3rd quadrant have both negative x and negative y values.
  3. We know that all radians with the base of 4 on the unit circle have the points of (\frac{\sqrt{2}}{2} ,\frac{\sqrt{2}}{2})
  4. Because we are in the 3rd quadrant and both x and y are negative we know the point of -\frac{3\pi }{4}  is (-\frac{\sqrt{2}}{2}, -\frac{\sqrt{2}}{2})

Finding the sin!

  1. Because we know that sin is asking us for the y value
  2. We can just look at the point and find the y value!
  3. the y value is -\frac{\sqrt2}{2} \\
  4. Because this fraction does not need to be rationalized we are good!
  5. Use a calculator to find the exact value and you get -0.70710678...
  6. The final answer is  -\frac{\sqrt2}{2} \\ or exact is −0.70710678...

Hope this helps!! Please mark Brainliest!

Define a sequence by a1=3 and an=3an−1. Find the first four terms of the sequence. Give a simplified integer answer.
aalyn [17]

Answer:

The first four terms are 3,9,27,81

Step-by-step explanation:

<u>Step :-1</u>

Given first term of sequence is a_{1} = 3

Given 'n' t h term is a_{n} = 3 a_{n-1}  .............(1)

here we put  n = 2 in equation (1)

a_{2} = 3a_{2-1}

a_{2} = 3 a_{1}    ..............2

put a_{1} = 3      in equation (2)

a_{2} = 3(3)  

a_{2} = 9

put n=3 in equation (1)

a_{3} = 3 a_{3-1}

a_{3} = 3a_{2}

a_{3} = 3 (9) = 27

put n= 4 in equation (1)

a_{4} = 3 a_{4-1}

a_{4} = 3 a_{3}

a_{4} = 3(27) = 81

The first four terms of the sequence is

3 , 9, 27 , 81 ....this is geometric sequence

a =3 and ratio term is r =3
