Work out the size of one of the exterior angles

hodyreva [135]

<u>Given</u><u> </u><u>Information</u><u> </u><u>:</u><u>-</u>

⠀

A polygon with 10 sides ( Decagon )

⠀

<u>To</u><u> </u><u>Find</u><u> </u><u>:</u><u>-</u>

⠀

The value of one of the exterior angles

⠀

<u>Formula</u><u> </u><u>Used</u><u> </u><u>:</u><u>-</u>

⠀

$\qquad \diamond \: \underline{ \boxed{ \pink{ \sf Exterior ~angle = \dfrac {360^\circ}{no. ~of~sides}}}} \: \star$

⠀

<u>Solution</u><u> </u><u>:</u><u>-</u>

⠀

Putting the given values, we get,

⠀

$\sf \dashrightarrow Exterior ~angle = \dfrac{360 ^\circ}{10} \: \: \\ \\ \\ \sf \dashrightarrow Exterior ~angle = \frac{36 \cancel{0}^\circ}{ \cancel{10}} \: \: \\ \\ \\ \sf \dashrightarrow Exterior ~angle = \underline{ \boxed{ \frak{ \red{36^\circ}}}} \: \star \\ \\$

Thus, the value of the exterior angles of a Decagon is 36°.

⠀

$\underline{ \rule{227pt}{2pt}} \\ \\$

Answer:

<h2>B. The amount of fuel used was lowest at speeds around 60km/h.</h2>

Step-by-step explanation:

The decreasing part is from (20,13) to (60,6), which gives an average rate of

$r=\frac{6-13}{60-20}=-\frac{7}{40}=-0.175$

Then, we have an increasing part from (60,6) to (120,10), which gives an average rate of

$r=\frac{10-6}{120-60}=\frac{4}{60}=0.067$

Basically, at 60 km/h the fuel used was 6 liters per 100 kilometers. Notice that the other velocities make the car to use more liters per kilometers.

Therefore, the amount of fuel used was lowest at speeds around 60 km/h.

A bank lent $200,500 for the development of two products. If the loan for priduct X was for $50,500 more than that for product Y

Kaylis [27]

Answer:

$75,000

Step-by-step explanation:

Let

x ----> amount lent for product X

y ---->amount lent for product Y

we know that

A bank lent $200,500 for the development of two products

so

$x+y=200,500$ ----> equation A

The loan for product X was for $50,500 more than that for product Y

so

$x=y+50,500$ ----> equation B

substitute equation B in equation A

$y+50,500+y=200,500$

solve for y

$2y=200,500-50,500\\2y=150,000\\y=\$75,000$

What transformation to the linear parent function, f(x) = x, gives the function g(x) = x + 8?

NeTakaya

Answer:

Shift 8 units up

Step-by-step explanation:

The given function is;

f(x)=x

and

g(x)=x+8

The function f(x) has its y-intercept at y=0.

The function g(x)=x+8 has its y-intercept at y=8

This implies that; the linear parent function f(x)=x is shifted up 8 units to obtain g(x)=x+8.
