antoniya [11.8K]

Answer:according to the formula of inscribed angle theorem

$3x + 22 = \frac{1}{2 } \times 134$

$3x + 22 = 67$

$3x = 67 - 22$

$3x = 45$

$x = \frac{45}{3}$

$x = 15$

A field bordering a straight stream is to be enclosed. The side bordering the stream is not to be fenced. If 1000 yards of fenci

sveta [45]

Answer:

x = 500 yd

y = 250 yd

A(max) = 125000 yd²

Step-by-step explanation:

Let´s call x the side parallel to the stream ( only one side to be fenced )

y the other side of the rectangular area

Then the perimeter of the rectangle is p = 2*x + 2* y ( but only 1 x will be fenced)

p = x + 2*y

1000 = x + 2 * y ⇒ y = (1000 - x )/ 2

And A(r) = x * y

Are as fuction of x

A(x) = x * ( 1000 - x ) / 2

A(x) = 1000*x / 2 - x² / 2

A´(x) = 500 - 2*x/2

A´(x) = 0 500 - x = 0

x = 500 yd

To find out if this value will bring function A to a maximum value we get the second derivative

C´´(x) = -1 C´´(x) < 0 then efectevly we got a maximum at x = 500

The side y = ( 1000 - x ) / 2

y = 500/ 2

y = 250 yd

A(max) = 250 * 500

A(max) = 125000 yd²

Anna is saving to buy a new cell phone. Her mother is helping Anna by contributing money each month. What is the ratio between t

Dmitry [639]

Answer:

Option D. 3:1, $120

Step-by-step explanation:

The complete question in the attached figure

Part 1) What is the ratio between the amount of money contributed by Anna and the amount contributed by her mother?

Let

x -----> the amount of money contributed by Anna

y ----> the amount of money contributed by her mother

we know that

Looking at the table

The value of x is equal to $x=\$30+\$60+\$90+\$120=\$300$

The value of y is equal to $y=\$10+\$20+\$30+\$40=\$100$

Find the ratio x/y

substitute the values

$\frac{x}{y}=\frac{300}{100}=\frac{3}{1}$

Part 2) What was the total amount saved in April?

we know that

To find out the total amount saved in April, adds Mon's contribution in April plus Anna's contribution in April

$(\$30+\$90)=\$120$
