Answer:

(y,z)=(3,5)\\\\ |(y,z)|=\sqrt{34}

Step-by-step explanation:

Given y(3, 1), z(0, 4)

-The ordered pair is written by summing their corresponding coordanates as below:

(y,z)=y(3,1)+z(0,4)\\\\=(3+0,1+4)\\\\=(3,5)

-We then calculate the magnitude of this ordered pair as following:

|y,z|=\sqrt{y^2+z^2}\\\\=\sqrt{3^2+5^2}\\\\=\sqrt{34}\\\\\therefore |(y,z)|=\sqrt{34}

Hence, the magnitude of the ordered pair is \sqrt{34}

The harbormaster decides how many trips the ferry needs to make for 37 cars. The ferry can carry 8 cars at a time. What is the b
katen-ka-za [31]

Answer:

By adding 1 to the quotient.

Step-by-step explanation:

The Harbormaster needs to arrange tripe for 37 cars

in one go ferry can carry a maximum of 8 cars

trips = 37/8 = 4.625 trips

Since the ferry can't go in decimals so we need one more trip to carry all the cars. Hence the best way to interpret the remainder of 37/8 is by adding 1 to the quotient which will make 5 trips.

Find the average rate of change of f ( x ) = 7x^2 − 6 on the interval [ 3 , a ] . Your answer will be an expression involving a
slega [8]

Answer:

\frac{7a^2-63}{a-3}

Step-by-step explanation:

So what is the average rate of change?  Basically, it's the slope.  In fact it's exactly the slope for a linear equation, but how do you find slope?

\frac{y_2-y_1}{x_2-x_1}

Sp we just plug the values in.  

x_1=3\\x_2=a\\y_1=7(3)^2-6=63-6=57\\y_2=7(a)^2-6

\frac{7a^2-6-57}{a-3}=\frac{7a^2-63}{a-3}
