Need help I got 23,294 as the answer but it’s not an option please explain how you got the answer.

Answer:

A

Step-by-step explanation:

Calculation seems correct to me, with d the distance and h the height of the plane, and i got the same value. Closest value is A tho, so i'd stick with it.

If you want to be pedantic about it, you can always divide the heigth by each value, and get the inverse tangent of each value. With A you get 17.995 which seems the best value you get

Since 2010, when 102390 Cases were reported, each year the number of new flu cases decrease to 85% of the prior year. Predict th

BaLLatris [955]

Answer:

20,158 cases

Step-by-step explanation:

Let $t=0$ represent year 2010.

We have been given that since 2010, when 102390 Cases were reported, each year the number of new flu cases decrease to 85% of the prior year.

Since the flu cases decrease to 85% of the prior year, so the flu cases for every next year will be 85% of last year and decay rate is 15%.

We can represent this information in an exponential decay function as:

$F(t)=102,390(1-0.15)^t$

$F(t)=102,390(0.85)^t$

To find number of cases in 2020, we will substitute $t=10$ in our decay function as:

$F(10)=102,390(0.85)^{10}$

$F(10)=102,390(0.1968744043407227)$

$F(10)=20,157.970260446597\approx 20,158$

Therefore, 20,158 cases will be reported in 2020.

If RS =14 and ST=9 , find RT. Use the number line below<br><br> RT=

Bingel [31]

Answer:

23

Step-by-step explanation:

RS = 14

ST = 9

That means S is in the middle of R and T because it has two line segments associated with it

RT = RS + ST

RT = 14 + 9

RT = 23

Given:

A right angled triangle.

To find:

The value of x.

Solution:

We have,

Base = x

Hypotenuse = $\sqrt{5}$

In a right angle triangle,

$\cos \theta = \dfrac{Base}{Hypotenuse}$

For the given triangle,

$\cos 45^\circ= \dfrac{x}{\sqrt{5}}$

$\dfrac{1}{\sqrt{2}}= \dfrac{x}{\sqrt{5}}$

Multiply both sides by $\sqrt{5}$ .

$\dfrac{\sqrt{5}}{\sqrt{2}}= x$

$\dfrac{\sqrt{5}}{\sqrt{2}}\times \dfrac{\sqrt{2}}{\sqrt{2}}= x$

$\dfrac{\sqrt{10}}{2}= x$

Therefore, the required value of x is $\dfrac{\sqrt{10}}{2}$ .
