Bella's Bakery charges $2.25 per cupcake

Mathematics
1 answer:
Sveta_85 [38]3 years ago
8 0

Answer:

6 cookies

Step-by-step explanation:

first, find how much money they spent on cupcakes

6 × $2.25 = $13.5

then, take $13.5 and subtract that by $24

$24 - $13.5 = $10.5

so the person spent $10.5 on cookies. divide the amount per cookie by $10.5

$10.5 ÷ $1.75 = 6

so they bought 6 cookies

Step-by-step explanation:

Given: f'(x) = x^2e^{2x^3} and f(0) = 0

We can solve for f(x) by writing

\displaystyle f(x) = \int f'(x)dx=\int x^2e^{2x^3}dx

Let u = 2x^3

\:\:\:\:du=6x^2dx

Then

\displaystyle f(x) = \int x^2e^{2x^3}dx = \dfrac{1}{6}\int e^u du

\displaystyle \:\:\:\:\:\:\:=\frac{1}{6}e^{2x^3} + k

We know that f(0) = 0 so we can find the value for k:

f(0) = \frac{1}{6}(1) + k \Rightarrow k = -\frac{1}{6}

Therefore,

\displaystyle f(x) = \frac{1}{6} \left(e^{2x^3} - 1 \right)

I need help with this question please.

Answer:

tan(2x)=-24/7

Step-by-step explanation:

Since tan(x)=sin(x)/cos(x)

We are going to need sin(x) any time, so lets find it right away.

To do this, remember that. sin(x)^2 + cos(x)^2=1

so. sin(x)= \sqrt{1 - (cos(x)^{2} )}=\sqrt{1-(-4/5)^{2} }

This leads to.

\sqrt{\frac{25-16}{25} } =\sqrt{\frac{9}{25} }=+/- 3-5

We have obtained two solutions, -3/5 and 3/5.

We need to pick one, since not all of them are correct for our scenario, in this case, we've been told that x belongs to the range [180, 270], in this range, sin(x)<0.

So in our previous solution, we have that sin(x)= -3/5

Now, to find tang(2x), we need to apply the definition

Tang(2x)=sin(2x)/cos(2x).

Lets remember that

sin(2x)=2*sin(x)*cos(x)

cos(2x)=cos(x)^2 - sin(x)^2.

Lets evaluate our given result.

sin(2x)=2*(-3/5)*(4/5)=-24/25

cos(2x)=(-4/5)^2 - (3/5)^2=7/25

Hence

tan(2x)= -(24/25) / (7/25)=-24/7

Answer: 70 cubic feet

Step-by-step explanation:

Hi, to answer this question we have to apply the formula of a rectangular prism.

V = length x width x height

Since the area of a rectangle is : A = length x width

So, the volume is also:

Volume = area x height

Replacing with the values given and solving for V:

V =35 ft2 x 2 ft = 70 cubic feet

Feel free to ask for more if needed or if you did not understand something.
