Help plz ill give extra points

UkoKoshka [18]

Answer:

79 degrees

Step-by-step explanation:

PQU is a straight line, so $\angle PQU = 180^\circ$ . This is also the sum of the four smaller angles. We can subtract 34+37+30 from 180 to get that $\angle SQT = 79^\circ$

(if right pls give brainliest :) )

Find all the zeroes of the polynomial function f(x)=x^3-5x^2+6x-30 in you use synthetic division show all three lines of numbers

jonny [76]

Answer:

5, $i\sqrt 6$ and $-i\sqrt 6$

Step-by-step explanation:

We are given that the polynomial

$f(x)=x^3-5x^2+6x-30$

We have to find the all the zeroes of the polynomial function.

$f(x)=0$

$x^3-5x^2+6x-30=0$

$x^2(x-5)+6(x-5)=0$

$(x-5)(x^2+6)=0$

$x-5=0$

$x=5$

$x^2+6=0$

$x^2=-6$

$x=\pm\sqrt{-6}=\pm i\sqrt6$

Using $\sqrt{-1}=i$

Hence, all the zeroes of the polynomial function are

5, $i\sqrt 6$ and $-i\sqrt 6$

Using a stopwatch, Tyrone determines it takes him 58. 2 minutes to travel 30 miles to work. The stopwatch measures to hundredths

nekit [7.7K]

The most accurate determination for the number of 45.36 feet per second Tyrone traveled on his way to work.

Given that,

Using a stopwatch Tyrone determines it takes him 58.2 minutes to travel 30 miles to work the stopwatch measures to hundredths of a minute going by the accuracy of the stopwatch.

We have to determine,

Which is the most accurate determination for the number of feet per second Tyrone traveled on his way to work?

According to the question,

Tyrone determines it takes him 58.2 minutes to travel 30 miles to work,

the stopwatch measures to hundredths of a minute going by the accuracy of the stopwatch are determined by,

$\rm Speed = \dfrac{Distance}{Time}$

Substitute the values in the equation,

$\rm Speed = \dfrac{Distance}{Time}\\\\Speed = \dfrac{30}{58.2}\\\\Speed = \dfrac{50}{97} \ miles \ per \ minute$

If 1 mile = 5,280 feet, then his speed is,

$\rm Speed = \dfrac{50}{97} \ miles \ per \ minute\\\\ Speed = \dfrac{50}{97} \times 5280 \\\\ Speed= \dfrac{26,400}{97}\ feet \ per \ minute\\$

And 1 minute = 60 seconds, then his speed is,

$\rm Speed= \dfrac{26,400}{97}\ feet \ per \ minute\\\\ Speed= \dfrac{26,400}{97} \times \dfrac{1}{60} \\\\ Speed = \dfrac{4400}{97} \ feet \ per \ second \\\\ Speed = 45.36 \ feet \ per \ second$
