What is the perimeter

Mathematics
2 answers:
Westkost [7]2 years ago

Answer:

The answer to your question is:  letter D

Step-by-step explanation:

First we need to find the distances between the points,

distance AB = 8       get it just by counting the points in the graph

distance AC = 9       get it just by counting the points in the graph

To know the distance BC, use the pythagorean theorem

         c2 = a2 +b2

         c2 = 8² + 9²

         c² = 64 + 81

          c² = 145

         c = 12.04

Finally, perimeter = AB + AC + BC

                              = 8 + 9 + 12.04

                               = 29.04 units

Answer:

D: 29.04

Step-by-step explanation:

AB = 7.5

AC = 7.5

P= 2x(LxB)

P= 2x(7.5+7.5)

P=2x15

P=30

Ans D is the closest.

Answer:

252 ft squared

Step-by-step explanation:

Since the radius of the circle is 3, then the diameter would be 6

Split the rectangle into 3

The way I split the shape is like the picture attached (with the blue lines).

Find the area of each rectangle which can be easily found by using the diameter of each circle (picture attached with black lines)

6*18=108

6*12=72

6*12=72

Add the areas of each rectangle.

108+72+72=252

Can anyone help me?
ArbitrLikvidat [17]

Answer:

The factored form of 4<em>m</em>³ – 28<em>m</em>² – 120<em>m</em> is 4<em>m</em>(<em>m</em> – 10)(<em>m</em> + 3). The zeroes of the function would be <em>m</em> = 0, <em>m</em> = –3, and <em>m</em> = 10.

Step-by-step explanation:

I'll give this a shot.

4<em>m</em>³ – 28<em>m</em>² – 120<em>m</em> = 0 — The original expression

4<em>m</em>³ – 28<em>m</em>² – 120<em>m</em> — Did that 0 have any purpose? I just deleted it.

4(<em>m</em>³ – 7<em>m</em>² – 30<em>m</em>) — There's a common factor in here, 4. Let's pull that aside.

4m(<em>m²</em> – 7<em>m</em> – 30) — Actually, there's <em>two</em> common factors. The second one is <em>m</em>! Let's pull <em>that</em> out too!

To factor an expression, you have to break apart the middle term, so to speak. That's only possible if you can find two numbers whose product equals that of the outside terms and whose sum equals the middle term. Here, I'm just dealing with numbers and putting that variable aside.

–30 = 10 × –3

–30 = –10 × 3

–30 = –2 × 15

–30 = 2 × –15 — To solve for any potential factors, let's find all the numbers integers that multiply to –30

Now let's see which one adds up to –7!

15 – 2 = 13 — it's not this one

2 – 15 = –13 — nor this one

10 – 3 = 7 — we're pretty close! Let's switch that negative

3 – 10 = –7 — here we go! Here's our numbers!

4<em>m</em>[(<em>m</em>² – 10<em>m</em>) + (3<em>m</em> – 30)] — now we break apart the middle term. This is <em>all</em> multiplied by 4<em>m</em>, so that still encases everything with brackets.

4<em>m</em>[<em>m</em>(<em>m</em> – 10) + 3(<em>m</em> – 10)] — Factoring the two expressions

4<em>m</em>(<em>m</em> + 3)(<em>m</em> – 10) — simplifying to find our answer! Ta-da!

What is the interquartile range if the data set? 5,911,13,16,16,19,21
max2010maxim [7]

Answer:

Step-by-step explanation:

5,9,11,(13,16),16,19,21

the mean(middle number) = (13 + 16) / 2 = 29/2 = 14.5

Q1 = (9 + 11) / 2 = 20/2 = 10

Q3 = (16 + 19) / 2 = 35/2 = 17.5

interquartile range (IQR) = Q3 - Q1 = 17.5 - 10 = 7.5 <==

Using all the rest of my points on this all just here for points answers will be reported
Semenov [28]
So the volume of the cylinder = pi r^2 * h
Height = 4 feet tall
Radius = 1 foot
So just do pi * 1^2 * 4
3.14 x 1^2 x 4 = 12.56 cubic feet
