Answer:

sqrt(41)

Step-by-step explanation:

The new point, A' has coordinates=(-3,2). The distance between them is sqrt((-8+3)^2+(6-2)^2)=sqrt(5^2+4^2)=sqrt(41)

The label on a package of bolts says each bolt has a diameter of 0.35 inch. To be in the package, the percent error of the diame
qaws [65]

Answer: No

Step-by-step explanation:-

Labeled diameter on the bolt = 0.35 inch

The observed diameter of the bolt= 0.33 inch

{\text {Percentage Error}}=|\frac{\text {labeled value}-{Observed value}}{\text {Observed value}}|\times 100\%

{\text{Percentage Error}=|\frac{0.35-0.33}{0.33}|\times 100\%=6.06\%

For the bolt to be in the package, the percent error must be less than 5%. As the percent error is 6.06% which is greater than 5%, the bolt cannot be in the package.

HURRY PLEASE!! Evaluate the expression below.
tatuchka [14]

Answer:

A

Step-by-step explanation:

Given

20 - ||  - 13 | + 17 |

Note the absolute value function always returns a positive value, that is

| - a | = | + a | = a, thus

= 20 - | | - 13 |+ 17 |

= 20 - | 13 + 17 |

= 20 - | 30 |

= 20 - 30

= - 10 → A

11) x – 3y = 3<br> How do you graph it?
kvv77 [185]

Hey!

------------------------------------------------

x – 3y = 3 is written in standard form. We can write in the slope-intercept form.

x - 3y = 3

x - 3y - x = 3 - x

3y = 3 - x

3y/3 = 3/3 - 3/x

y = 1 - 3/x

y = 1/3x - 1

Now, we know that the y-intercept is -1 and the slope is 1/3

------------------------------------------------

Hence, the answer is \Large\boxed{\mathsf{In~picture}}

------------------------------------------------

Hope This Helped! Good Luck!

A school bus during morning pickups to calculate its average speed between 2.8 km and 4.2 km.
kifflom [539]

<u>Answer: </u>

Option (c)

The average speed between 2.8 km and 4.2 km is 42 km/h

<u>Explanation:</u>

Given, the distance between 2.8 km and 4.2 km is 4.2 - 2.8 = 1.4 km

Time (in hours) between 2.8 km and 4.2 km

    = 0.084 – 0.051

     = 0.033 hr

Speed =\frac{Distance}{Time}

Speed = \frac{1.4}{0.033}

Speed = 42.4 km/hr = 42 km/h (rounded to nearest)

Therefore, the average speed between 2.8 km and 4.2 km is 42 km/hr

Hence, Option (C) is correct
