Jules kicks a soccer ball off the ground and into the air with an initial velocity of 25 feet per second. Assume the starting he

yuradex [85]

Hello,

y=-g/2 t²+25 t is the trajectoire with g=9.81 m/s²

y=-g/2 (t²-25*2/g t)
==>y=-g/2(t²-2*25/g t +25²/g²)+25²/g² * g/2
==>y=-g/2(t-25/g)²+25²/(2g)

==> h=25²/(2g)=625/(2*9.81*3.28084)=9,709479... feet
(for 1m=3.28084 feet)

Look at the picture below. What is tan(A – B)? Thanks!

Natalka [10]

Step-by-step explanation:

the mistake was made when the value of cos 3 pi over 2 was calculated.

tan(A-B)= ?since tan=sin/cos

sin(A-B) = sinAcosB-cosAsinB

cos(A-B) cosAcosB+sinAsinB

divide by cos on the RHS

tan(A-B)= tanA-tanB

1+tanAtanB

What is the answer to #3

svetlana [45]

Answer:

Step-by-step explanation:

The angles of any triangle add up to 180 degrees.

$8x + (7x+2) + (4x+7) = 180 \\ 19x+9=180 \\ 19x=181 \\ x=9$

Putting this value into the expressions for the angle measures:

$m\angle J=7x+2=65 \\ m\angle K=8x=72\\m\angle L=4x+7=43$

Lynn takes out a loan for $7540 that charges an annual simple interest rate of 6.5%. She does not make any payments for 2 1/2 ye

Amanda [17]

Answer:

The Amount after 2 $\dfrac{1}{2}$ years is $8765.25

Step-by-step explanation:

Given as :

The principal loan amount = p = $7540

The rate of interest = r = 6.5%

The time period of loan = t = 2 $\dfrac{1}{2}$ years = $\dfrac{5}{2}$ years = 2.5 years

Let The Amount after 2.5 years = $A

Now, From Simple Interest method

Simple Interest = $\dfrac{\textrm principal\times \textrm rate\times \textrm time}{100}$

Or , s. i = $\dfrac{\textrm p\times \textrm r\times \textrm t}{100}$

Or, s.i = $\dfrac{\textrm 7540\times \textrm 6.5\times \textrm 2.5}{100}$

Or, s.i = $\dfrac{122525}{100}$

Or, s.i = $1225.25

So, The simple interest = s.i = $1225.25

Now, Again

∵ Amount = Principal + interest

So, A = $7540 + $1225.25

∴ A = $8765.25

So, The Amount after 2 $\dfrac{1}{2}$ years = A = $8765.25

Hence,The Amount after 2 $\dfrac{1}{2}$ years is $8765.25 Answer
