Answer:

Step-by-step explanation:

Calling it blocks is a little weird. but a good way to do it is to move left or right until you are over or below where you want to go then move up or down accordingly.  Each move, left, right up or down will count as one block.

So from the fire station you go 1 to the right and then 6 down, for a total of 7.  then from the library  it's 3 right then 4 up, which is 7 again.  7 to the first stop then 7 to the second makes 14 total.  

If there's something you don't get let me know.

the logarmithmic functions, f(x)=logx and g(x), are shown on the graph. what is the equation that represents g(x)? explain.​
mestny [16]

Answer:

g(x) = log(x+1) + 4

Step-by-step explanation:

If a curve has been translated (shifted or slid) you can add to or subtract from the x to show horizontal (left or right) shifts and add or subtract a number tacked onto the end of the equation to cause the vertical shift (up or down).

The curve for g(x) is shifted left 1 unit. So change the x to x+1. Left and right shifts are a little backwards from what you might think. But left shift is a +1.

Vertical shifts adjust the way you would think they should. UP shift 4 units is a +4 on the end of the equation. See image.

True or False The image of a translation is always congruent to the pre-image.
posledela
True. The image of a translation is always congruent to the pre-image.

Proof: every point of the pre-image is move exactly the same distance and the same direction. That means that the shape stay the same but it is just located in a different place.

Hope this helps :)

A text font fits 12 characters per inch. Using the same font, how many characters can be expected per yard of text? There are 12
Bond [772]

Answer:

432 characters

Step-by-step explanation:

First we can convert 12 characters per inch in to characters per feet. Knowing that there are 12 inches per foot we know we have to multiply the 12 characters per inch by 12, giving us 144 characters per foot. Now we have to convert characters per foot to characters per yard. Knowing there are 3 feet per yard we know we have to multiply 144 characters per foot by 3, giving us a final answer of 432 characters per yard of text.

How many cubic centimeters of water can this paper cone cup hold?
Igoryamba

Answer:

150.72 cubic centimeter

Step-by-step explanation:

Given:-

Height of cone (h) = 9cm

Diameter of cone(d)=8cm

radius of cone(r)=\frac{d}{2}=\frac{8}{2} =4cm

To calculate= Volume of cone(V_{cone})

Volume\ of\ cone(V_{cone}) =\frac{1}{3} \times \pi \times r^{2} \times h

=\frac{1}{3} \times 3.14\times 4^{2} \times 9

Volume of cone(V_{cone}) =150.72\ cubic\ centimeter

Therefore paper cone cup can hold 150.72 cubic centimeter of water.
