ABCD is a square
=> Δ ABD is a isosceles right triangle at A
using pythago theorem, we have:
AB² + AD² = BD²
=> 2AD² = 4
⇔ AD² = 2
⇒ AD = √2
through O, draw EF parallel to AD and BC
=> EF is diameter
because EF//AD => EF = AD = √2 (because circle O is inscribed the square ABCD)
=> the area of the circle is [tex]S=\frac{(\sqrt{2})^{2} }{4}.\pi =\frac{\pi }{2}[/tex]

What is the equation of the line through the origin and (-4,-9)?
A. y= 4x
B. y = 4/9x
c. y = 9/4x
D. y = 9x
Answer: c) y = 9/4 · x
Step-by-step explanation:
We can use slope formula to find the slope of a line that passes through two points (x₁ , y₁) and (x₂ , y₂)
m = ∆y/∆x = y₂-y₁/x₂-x₁Given points are: P(x₁ , y₁) = (0, 0) and Q(x₂ , y₂) = (-4, -9)
Substituting these two known points in the slope formula, we have:
m = (-9-0)/(-4-0) = -9/-4 = 9/4Now we can use the point-slope formula to write the equation of a line given a point on the line and the slope of the line:
m = 9/4 , given point P(x₁ , y₁) = (0, 0)
Formula = (y-y₁) = m(x-x₁) (y-0) = 9/4(x-0) y = 9/4 · xAnswer: c) y = 9/4 · x
SpymoreNadia finds out her favorite horse family population is increasing at a constant rate. The horse family was at 24 in 2011 and is currently at 32 in 2014. Find an equation in point slope form that models the population growth and predict the number of horses in 2020.
Answer:
The equation is p = (8/3) t + 24
In 2020, we will have about 48 horses.
Step-by-step explanation:
In 3 years the family increased by 32 - 24 = 8.
So the constant of proportionality = 8/3.
The required equation is p = (8/3)tx + 24
where p = the population and t is the number of years after 2011.
So in 2020 we can predict that in 2020 the number of horses
= (8/3) * 9 + 24
= 72/3 + 24
= 24 + 24
= 48.

Which expression has a value of 60?
1. 360 divided by 60
2. 3600 divided by 6
3. 3600 divided by 60
4. 3600 divided by 600
3600 divided by 60 is equal to 60. The correct option is 3.
To find the expression that has a value of 40, to evaluate each expression:
1.
360 divided by 60:
Divide 360 by 60 is equal to 6.
So, this is incorrect option.
2.
3600 divided by 6:
Divide 3600 by 6 is equal to 600.
So, this is incorrect option.
3.
3600 divided by 60:
Divide 3600 by 60 is equal to 60.
So, this is correct option.
4.
3600 divided by 600:
Divide 3600 by 600 is equal to 6.
So, this is incorrect option.
Hence, out of the four expressions, the third one, 3600 divided by 60, has a value of 60. So the correct answer is 3 (3600 divided by 60).

Each exterior angle of a regular polygon is 9°
Calculate the number of sides of the polygon
Answer:
40
Step-by-step explanation:
The sum of the exterior angles of a polygon = 360°
Divide this by the value of 1 exterior angle to find the number of sides n
n = 360 ÷ 9 = 40
Answer:
Required Answer :-Let the number of sides=x
Each angle measures 9°As we know that in a polygon
[tex]{\boxed{\sf Sum\;of\:exterior\:angles=360°}}[/tex]

What is the length of EF in the right triangle below? E 17 13 F
A. 458
B. 458
C. 4
D. 1120
E. 30
F. 120
Answer:
The answer is D. √120
Step-by-step explanation:
Using the pythangorean theorem when solving the missing side of a right triangle, so given a^2 + b^2 = c^2. We have side c, and a so we must rearanged this to fit side b.
So: a^2 + b^2 = c^2 → b^2 = c^2 - a^2 →
b = √(c^2 - a^2).
Given side c or the hypotenuse is 17, and a is 13. side b must have a length of:
√(17^2-13^2) = √(289 - 169) = √120
The value of the length of EF in the right triangle is,
⇒ EF = √120
What is Pythagoras theorem?
The Pythagoras theorem states that in a right triangle, the square of the hypotenuse is equal to the sum of the square of the other two sides.
We have to given that;
In triangle DEF,
DF = 13
DE = 17
Hence, By using Pythagoras theorem,
⇒ DE² = EF² + DF²
⇒ 17² = EF² + 13²
⇒ 289 = EF² + 169
⇒ EF² = 289 - 169
⇒ EF² = 120
⇒ EF = √120
Thus, the length of EF in the right triangle is,
⇒ EF = √120

In the winter, Grandma Helen knits scarves for her family members. It took her 70 minutes to make a 35-inch-long scarf for her grandson, Sean. Now, she wants to make a 50-inch-long scarf for her granddaughter, Shannon. If Grandma Helen knits at the same rate, how many minutes will it take her to make Shannon's scarf?
Answer:
100 minutes
Step-by-step explanation:
Set up a proportion where x is the amount of minutes it will take her to make the 50 inch long scarf:
[tex]\frac{70}{35}[/tex] = [tex]\frac{x}{50}[/tex]
Cross multiply and solve for x:
35x = 3500
x = 100
So, it will take her 100 minutes to make Shannon's scarf

the vector to fully describe the single transformation which takes triangle A to triangle
Answer:
The translation vector from A to B is (-4,6)
Step-by-step explanation:
A translation vector is a type of transformation that moves a figure in the coordinate plane from one location to another.
All the vertices of the figure are translated by the same vector, and the resulting figure is shifted horizontally and vertically.
The vertices of triangle A are:
(3,-1) (1,-4) (3,-4)
The corresponding vertices of triangle B are:
(-1,5) (-3,2) (-1,2)
Subtracting the vertices of B from vertices of A:
(-4,6) (-4,6) (-4,6)
Note they are result in the same translation vector, thus:
The translation vector from A to B is (-4,6)

Maricella solves for x in the equation 4 x minus 2 (3 x minus 4) + 4 = negative x + 3 (x + 1) + 1. She begins by adding –4 + 4 on the left side of the equation and 1 + 1 on the right side of the equation. Which best explains why Maricella’s strategy is incorrect?
The multiplication that takes place while distributing comes before addition and subtraction in order of operations.
In order to combine like terms on one side of the equation, the inverse operation must be used.
When the problem is worked in the correct order, the numbers that Maricella added are not actually like terms.
Maricella did not combine all three constants on both sides of the equation; she combined only two.

The multiplication that takes place while distributing comes before addition and subtraction in order of operations.

Eight bags of chips and four sodas cost $5. Four bags of chips and eight sodas costs
$7. How much does a bag of chips cost? How much does a soda cost?
Answer:
let x be chips and y be sodas

4x + 8y = 7------> second hint
0.25 cents is how much chips costs
and 0.75 cents is how much sodas costs
Answer: Each bag of chips is $0.25, each soda is $0.75.
(0.25 x 8) + (0.75 x 4) = 5
2 + 3 = 5
(0.25 x 4) + (0.75 x 8) = 7
