A triangular arch is to be constructed over a busy street in order to place a sky bridge traversing one side of the triangle to

the other. The base of the arch spans the width of the street, which is 20 feet. Each side of the triangular arch measures 30 feet in length. If the entrances of the sky bridge lie at the midpoints of each side of the triangular arch, and the bridge is to be parallel to the street below, how long will the sky bridge be?

aniked [119]

Answer:

Option D

Step-by-step explanation:

The objective of the survey is to assess the satisfaction level of the customers.

Out of the options given, option D is the closest to be used as a basis for gauging the satisfaction level of customers. Option A is irrelevant to the subject under discussion, as it is bears no semblance to the topic.

Option B also has this same tendency, and tend to view the satisfaction from the customers annual income, and not from the firm or its products. Using this definitely could give a measurement error.

Option C talks on inability of the user/customer of the media player to set the time. This failure is borne by the user, and not an inherent fault in the media player. As such, using this as a basis could lead to a measurement error.

Option D is the most suited for the survey.

SOMEONE NEEDS TO EXPLAIN WHY 1.40 DIDNT WORK ON MY QUESTION 2.1/1.488
Zanzabum

My calculator shows that

(2.1)/(1.488) = 1.41129

which is approximate. If you want the result to two decimal places, then it would be 1.41 and not 1.40

Try 1.41 and it should work out, assuming your teacher wants two decimal places.

Evaluate the following functions for the given value.<br> 19. f(x) = -x3 + x2; -2
suter [353]

Answer:

12

Step-by-step explanation:

f(x) = -x^3 + x^2

Let x = -2

Evaluate the expression

f(-2) = -(-2)^3 + (-2)^2

       = - (-2)*(-2) * (-2)  + ( -2) * (-2)

       = -(-8) + ( 4)

    = 8 + 4

   = 12

Finger [1]

Answer:

p>-1    or    p<-19

Step-by-step explanation:

4p-10<6p-8 (add 10 to each side)

4p< 6p+2 (subtract 6p from each side)

-2p<2  (divide by -2 and switch the sign)

p>-1

10p+16<9p-3 (subtract 16 from each side)

10p<9p+-19 (subtract 9p from each side)

p<-19
