The table shows the volume of water in a tank after it has been filled to a certain height.

Lilit [14]

Functions and tables can be used to model real world situations.

The equation that represents volume is: $\mathbf{V(h) = 1.05(h)^3}$

From the table, we have:

$\mathbf{h \to V}$

$\mathbf{0 \to 0}$

$\mathbf{1 \to 1.05}$

$\mathbf{2 \to 8.40}$

$\mathbf{3 \to 28.35}$

The table can be rewritten as:

$\mathbf{h \to V}$

$\mathbf{0 \to 1.05 \times 0^3}$

$\mathbf{1 \to 1.05 \times 1^3}$

$\mathbf{2 \to 1.05 \times 2^3}$

$\mathbf{3 \to 1.05 \times 3^3}$

Replace 0, 1, 2 and 3 with h

$\mathbf{h \to 1.05 \times h^3}$

The above expression means that:

$\mathbf{V(h) = 1.05 \times h^3}$

Rewrite as:

$\mathbf{V(h) = 1.05(h)^3}$

Hence, the equation that represents volume is: $\mathbf{V(h) = 1.05(h)^3}$

Find the length of the hypotenuse of this triangle

Grace [21]

To find the hypotenuse of a right triangle, use the formula for the pythagorean theorem. This is a^2+b^2=c^2, with the two side lengths as a and b and the hypotenuse being c. So, 28^2+21^2=1225
1225 is your hypotenuse length!

Answer:

The calculated value t = 2.038< 2.145 at 0.05 level of significance

Null hypothesis is accepted

There is the average rate is less than μ ≤ 4

Step-by-step explanation:

Step(i):-

The Population of the mean 'μ' =4

sample size 'n' = 16

sample mean 'x⁻' = 4.53

given sample standard deviation 's' = 1.04

level of significance α = 0.05

Step(ii):-

Null hypothesis:H₀ : There is no significance difference between two means

Alternative hypothesis : H₁: There is significance difference between two means

Test statistic

$t = \frac{x^{-} - mean}{\frac{S}{\sqrt{n} } }$

$t = \frac{4.53-4}{\frac{1.04}{\sqrt{16} } }$

t = 2.038

Degrees of freedom ν = n-1 = 16-1 =15

t₀.₀₂₅ = 2.145

Conclusion:-

The calculated value t = 2.038< 2.145 at 0.05 level of significance

Null hypothesis is accepted

There is the average rate is less than μ ≤ 4

You open a savings account with a beginning balance of $600. You plan on depositing $50 every month until you have enough money

telo118 [61]

Answer:

48 months

Step-by-step explanation:

first take how much you need and add how much you want to leave, so 2500+500=3000. Then delete 600 from 3000, which will give you $2400. divide $2400 by 50 which gives you 48. it will take 48 months to get enough money to purchase a car at $2500 and leave $500 in the account.

What is -4/9*(-7/9)?

seropon [69]

Hello! So both numbers are negative, so the answer will definitely be positive. All you have to do is multiple straight across. 4 * 7 is 28 and 9 * 9 is 81. That’ll make the fraction 28/81. The product is 28/81.
