Answer:

RS = 4.9

Step-by-step explanation:

Because the sides involved are hypotenuse and adjacent to the angle we use Cosine:

\frac{RS}{7} = Cos(46)

RS = 7Cos(46)

RS = 4.86.....

RS = 4.9

Again we have to apply trigonometry ie sine angle

sin46=QS/RS

sin46=sin45=√2 (for our convinience)

RS=7/√2

=4.9

Hope this helps.

A population, P, of birds is doubling in size each year, according to the model P = 100(2t), where t reperesents years. What was
Usimov [2.4K]
The initial population size can be found by substituting values for "T"

At time zero, there are no birds because 

·(2×0)×100=0

At time 1 there would be 200 birds this is because

·(2×1)×100=200

And the start besides time Zero would be at time 1, there for the initial population would be represented by the population at time 1, which is 200.

In conclusion the initial population in this equation would be 200.

Jacob and issac decided to run to the basketball court after school the basketball court is 5 1/4 Miles from school the boys run
GenaCL600 [577]

Answer: 1\dfrac{5}{9}\text{ minutes}

Step-by-step explanation:

Complete question is provided in the attachment below.

Given: Jacob and Issac decided to run to the basketball court

Distance between basketball court and school = 5\dfrac{1}{4} miles

=\dfrac{21}{4} miles

Speed = 3\dfrac{3}{8} miles per hour

=\dfrac{27}{8} miles per hour

Since, time = (distance) ÷ ( speed)

Now, the time taken by boys to arrive at the basketball court = \dfrac{21}{4}\div\dfrac{27}{8} hours

=\dfrac{21}{4}\times\dfrac{8}{27}\\\\=\dfrac{7\times2}{9}=\dfrac{14}{9}\\\\=1\dfrac{5}{9}\text{ minutes}

Hence, the required length of time = 1\dfrac{5}{9}\text{ minutes}
