A tennis ball is launched from a catapult from the ground with an initial velocity of 26fps. What is the maximum height of the b

Lady bird [3.3K]

Answer:

10.5618feet, 0.8125sec

Step-by-step explanation:

Given the height reached by the catapult expressed by the equation H=-16T^2+26T

At the maximum height, the velocity of the object is zero, hence;

v = dh/dt = 0

-32t + 26 = 0

-32t = -26

t = 26/32

t = 0.8125secs

Hence it will attain the maximum height after 0.8125second

Substitute t = 0.8125s into the expression to get the maximum height

H=-16t^2+26t

H = -16(0.8125)^2 + 26(0.8125)

H = -16(0.6602) + 21.125

H = -10.5632+21.125

H = 10.5618

hence the maximum height reached by the ball is 10.5618feet

Shang has a coupon for 15% off he decided to buy a shirt for 16.95 the sales tax rate is 6% what is his final cost

kati45 [8]

Answer:

After the coupon and sales tax were applied, he paid $15.27 for the shirt.

Step-by-step explanation:

We are given that a shirt is $16.95. This is reduced by 15% due to the coupon.

$100\% - 15\% = 85\%$

Therefore, 85% of the shirt price is still active.

$\displaystyle \frac{85}{100}=0.85$

We can multiply this value by the shirt price to find the current price.

$16.95 \times 0.85 = 14.4075 \approx \$14.41$

However, the shirt also has a sales tax of 6% applied after the coupon.

$\displaystyle \frac{6}{100} = 0.06$ a

Now, we need to find the total price for the shirt.

$\displaystyle 14.41 \times 1.06 = 15.2746 \approx \$15.27$

Therefore, he paid $15.27 for the shirt.

Write the expression that shows "3 times the<br>sixth power of 10."

photoshop1234 [79]

Answer:

$10^6^*^3\\\\or\\\\10^1^8$

Step-by-step explanation:

the 6th power of 10 would be 10^6, then you'd multiply it by 3 which would make it 10^6*3

you could then simplify it and say 10^18 (multiply the exponents [6 and 3])
