Step-by-step explanation:

In ∆PQR and ∆TSU

\because\begin{cases}PQ\approx TS \\ QR\approx TU \angle \\ Q\approx \angle T\end{cases}

\therefore{∆PQR\approx ∆TSU(\because SAS)}

And

  • <Q is greater than <T
  • So SU will be less than PR(22cm)

The rate at which rain accumulates in a bucket is modeled by the function r given by r(t)=10t−t^2, where r(t) is measured in mil
mars1129 [50]

Answer:

36 milliliters of rain.

Step-by-step explanation:

The rate at which rain accumluated in a bucket is given by the function:

r(t)=10t-t^2

Where r(t) is measured in milliliters per minute.

We want to find the total accumulation of rain from <em>t</em> = 0 to <em>t</em> = 3.

We can use the Net Change Theorem. So, we will integrate function <em>r</em> from <em>t</em> = 0 to <em>t</em> = 3:

\displaystyle \int_0^3r(t)\, dt

Substitute:

=\displaystyle \int_0^3 10t-t^2\, dt

Integrate:

\displaystyle =5t^2-\frac{1}{3}t^3\Big|_0^3

Evaluate:

\displaystyle =(5(3)^2-\frac{1}{3}(3)^3)-(5(0)^2-\frac{1}{3}(0)^3)=36\text{ milliliters}

36 milliliters of rain accumulated in the bucket from time <em>t</em> = 0 to <em>t</em> = 3.

Someone please help me mate i'm not smart!

Let's use f(x) for the first one and g(x) for the second. 
n is the number of songs downloaded, t is the time in years, and m is the time in months. 

f(x) = 125t + 10m
g(x) = 50 + n

For 2, substitute 1 for t and 12 for m. 
For 4, solve f(x) = g(x).
For 5, solve g(x) for n=(14*12). Compare it to the value of f(x) for t=1 and 12=m.

Answer:

\frac{7}{15}

Step-by-step explanation:

Let 1 unit be 0.4666...

16 units = 0.4666...*16=7.4666...

15 units = 7.4666...-0.4666...

15 units = 7

1 unit = \frac{7}{15}
