Answer:

We have 150(1.05)⁷ = 211.07

Step-by-step explanation:

We need to find the value of A(t) = 150(1.05)⁷ to the nearest hundredth.

A(t) = 150(1.05)⁷ = 211.0650634

Rounding the value in to nearest hundredth

150(1.05)⁷ = 211.0650634 = 211.07

So we have 150(1.05)⁷ = 211.07

Nearest hundredth means the second decimal digit.

$150( {1.05}^{7} ) = 211.065$

Notice that the third digit is 5 so the second digit rounds to 7.

$= 211.07$

Hope that helps you :)

Josh has a aquarium 30 inch deep.it takes him 5 min to fill the bucket with 3 inch of water.he estimates that it will take him u

Burka [1]

Answer:

Step-by-step explanation:

From the information provided, we can say that he is not correct. This is because the depth of the water is the only measurement that he is using to make his estimate. Comparing the depth of the aquarium and the bucket is one measurement, but both the aquarium and bucket are most likely of different shapes and sizes. Therefore, this equates to more buckets for the same amount of depth in the aquarium. To get a proper estimate on how long it will take he needs to calculate the volume of water in the bucket and compare it to the volume of water needed to fill the aquarium.

Carrie is driving to a friend’s house for the weekend. The friend lives in a town 160 mi. away. So far, Carrie has driven 64 mi.

ankoles [38]

Divide the amount she drove by the total amount she needs to drive, them multiply that answer by 100 to make it a percent. This will give you the percentage she drove. To find the percentage she has left,, subtract from 100%.

64 / 160 = 0.4

0.4 * 100 = 40% ( percent she has already driven)

100% - 40% = 60% left.

I'm assuming you mean $f(x) = (e^x + 5x)^2$ , not $f(x) = (e x + 5x)2$ , like your prompt suggests.

First, let's figure out what rule we can use. A likely noticeable one is the Power Rule, which says the following:

$\dfrac{d}{dx} [u^a] = a(u)^{a-1} du$

Applying this, we can solve for the derivative:

$f'(x) = 2(e^x + 5x) (e^x + 5)$

Apply the Power Rule

While you can simplify the expression to your liking, I believe that this form is not overly complex and will thus leave it as is.

Thus, our answer is:

$f'(x) = \boxed{2 (e^x + 5x)(e^x + 5)}$

Jana joined a music club that offered her 5 CDs for a total of 3.00 if she agreed to purchase an additional 10 CDs for 15.00 eac

Hunter-Best [27]

Answer:

Average price, excluding taxes, for each CD is <u>10.20</u>.

Step-by-step explanation:

Given:

Cost of first 5 CDs, $C_1 = 3.00$

Cost of each additional CD = 15.00

Now, cost of 10 additional CDs is the product of cost of one CD and total number of additional CDs. Therefore,

Cost of 10 additional CDs is, $C_2=15.00\times 10=150.00$

Now, total CDs purchased by Jana are, $N=5+10=15$

Total cost of the 15 CDs purchased is given as:

$C_T=C_1+C_2=3.00+150.00=153.00$

Now, average price, excluding taxes, for each CD is given as:

$\textrm{Average price}=\frac{\textrm{Total cost of purchase}}{\textrm{Total number of CDs purchased}}\\\\\textrm{Average price}=\frac{C_T}{N}=\frac{153.00}{15}=10.20$

Therefore, the average price, excluding taxes, for each CD is 10.20.
