1 answer:

3 0

I think it is A. Because it says that 1/3 is dividing the difference of 15 and an number, furthermore "one third" mean divide by 3.

The bakery bought four bags of flour containing 3.5 kg each 475 g of flour are needed to make a batch of muffins and 0.65 kg is

brilliants [131]

First we have to find total mass of flour.
4*3.5kg=14kg
Now we are calculating how much flour we used for muffins
475g=0.475kg
0.475kg*4muffins=1.9kg
and now how much flour we used for bread
0.65kg*5bread=3.25kg
Finally we can subtract 1.9 and 3.25 from 14kg
14kg-1.9kg-3.25=8.85kg - its the answer

Find the average value of the function f(t)=cos13(5t)sin(5t) f(t)=cos13⁡(5t)sin⁡(5t) on the interval [4,10].

Vilka [71]

The average value is given by

$\displaystyle\frac1{10-4}\int_4^{10}\cos^{13}5t\sin5t\,\mathrm dt$

Setting $y=\cos5t$ , you get $\mathrm dy=-5\sin5t\,\mathrm dt$ , and the integral becomes

$\displaystyle-\frac1{30}\int_{\cos20}^{\cos50}y^{13}\,\mathrm dy$
$=-\dfrac1{30}\dfrac{y^{14}}{14}\bigg|_{y=\cos20}^{y=\cos50}$
$=-\dfrac{\cos^{14}50-\cos^{14}20}{420}\approx-0.00145$

If an object is dropped from a height of 96ft, the function h(t) = -62 + 96 gives the height of the object after t seconds. When

Shalnov [3]

Answer:

Step-by-step explanation:Since we want to know how much time elapsed since the object was launched until it ht the ground. At the ground, the height is 0.

Therefore the equation h(t) = 80t – 16t2 becomes 0= 80t – 16t2

Solving the equation for t gives 80t =16t2 or 16t=80 or t=5sec

The object hits the ground 5 seconds after it is launched.
