Y=mx+b
ok, so notice that b is constant, doesn't change, when x=0, then y=b
that is the starting value

it is stated that he has 41 at the begining so

y=mx+41

alright
so we are also given
when x=5, y=66
so find m
66=5m+41
miinus 41 from both sides
25=5m
divide both sides by 5
5=m


the equation is
y=5x+41

Hi again here's the picture
pshichka [43]

Answer:

<h2>351.88 m</h2>

Step-by-step explanation:

Given,

D = diameter of semicircular part = 42 m

L = Length of straight part = 110 m

Now, let's find the perimeter:

= 2 ( length of semi-circle + length of straight part )

= 2( \frac{\pi \: d}{2}  + l)

Plug the values

= 2( \frac{3.14  \times 42}{2}  + 110)

Calculate the product

= 2( \frac{131.88}{2}  + 110)

Divide

= 2 (65.94 + 110)

Calculate the sum

= 2 \times 175.94

Calculate

= 351.88 \: m

Hope this helps..

Best regards!!

Find the area of the trapezoid. Pls explain and I will mark brainliest.
timama [110]

Answer:

  • B. 191.4 m²

Step-by-step explanation:

Split the trapezoid as pictured below

Find its height and the upper base, then find the area of the trapezoid.

There are 3 pieces, two of them are 45°×45° and 30°×60°×90° triangles

  • The ratio of sides of a 30°×60°×90° triangle is  1 : √3 : 2
  • The legs of a 45x45 triangle are equal

<u>The above mentioned properties give us:</u>

  • h = 16/2 = 8 m
  • b = 8√3 ≈ 13.85 m
  • a = h = 8 m

<u>Now find the area:</u>

  • A = 1/2( 13 + 8 + 13.85 + 13)*8 = 191.4 m²

Correct choice is B

Find the area of each figure. Use 3.14
grigory [225]
<h3>Answer:  23.13 square meters</h3>

===============================================================

Explanation:

The top and bottom semicircles can be joined to form a full circle. The same can be said about the left and right semicircles. Each circle has diameter 3 and radius 1.5

The area of one circle is

A = pi*r^2

A = 3.14*(1.5)^2

A = 7.065

So two circles doubles to 2*7.065 = 14.13 square meters in area.

Then the last step is to add on the area of the 3 by 3 square (area 3*3 = 9) to get 14.13+9 = 23.13

This area is approximate because pi = 3.14 is approximate. Use more decimal digits in pi to get a more accurate area. However, your teacher wants you to use this specific value so it's best to stick with 23.13
