A coral reef is 2 miles due south of its closest point along a straight shoreline. A visitor is staying in a cabin that is 4 mil
Goshia [24]

Answer:

5.54 miles

Step-by-step explanation:

1. Assume she runs up to a point that is x miles to the east of the coral reef:

distance running =

distance swimming =

2. Times:

time= distance / speed

time running =

time swimming =

3. Total time

time running + time swimming:  

             

4. Minimize time

The minimum time is when the derivative of the function of time is zero.

Find the derivative of T(x), using rule of the sum, the derivative of the sum is the sum of the derivatives, and the chain rule:

        

Solve for x:

         

5. Distance the visitor should run to minimize the time

Hence, the visitor should run 5.54 miles.

PQR is an isosceles triangle in which pc=pr m and n are points on PQ and PR such that angle MQR =angle NQR Prove that triangle Q
Elan Coil [88]

Answer:

We are given that triangle PQR is an isosceles triangle in which PQ = PR .

Since the base angles of an isosceles triangle are equal,

angle PQR = angle PRQ  

Also, And we are given that

angle MRQ = angle NQR

In ΔQNR and  ΔRMQ

∠NQR=∠MRQ (given)

QR = QR   (common)

-triangles QNR is congruent to triangles RMQ - ASA - angle side angle

Question 1
olga_2 [115]

Step-by-step explanation:

(7r+5s)^2

use the pattern

(a+b)^2=a^2+2ab+b^2

(7r+5s)^2=(7r+5s)(7r+5s)

Apply FOIL method to multiply the parenthesis

(7r+5s)^2=(7r+5s)(7r+5s)

(7r+5s)(7r+5s)\\49r^2+35rs+35rs+25s^2\\49r^2+70rs+25s^2

Compare the expression with (a+b)^2=a^2+2ab+b^2

The value of a=7r and the value of b=5s

Answer :

a=7r ,  b=5s

the total cost after tax to repair Kimber’s cracked phone is represented by 00.4(30h)+30h Where h represents the number of hours
Serjik [45]

we have that

the total cost is

0.040(30h)+30h

In this equation  the term 30h represent the cost due to h hours at at unit of 30

and the term 0.040(30h) is equal to calculate the 4% of (30h)

so

in this problem the tax rate is equal to 4%

therefore

<u>the answer is</u>

The term 0.040(30h) represents the amount of tax she must pay
