The standard equation of a unit circle is

x²+y²=1

So, if we want a radius of 4, we need to square it.

so we have x²+y²=16

Answer:

x^2 + y^2 = 16

Step-by-step explanation:

The equation of a circle is given by

(x-h)^2 + (y-k)^2 = r^2  where (h,k) is the center and r is the radius

(x-0)^2 + (y-0)^2 = 4^2

x^2 + y^2 = 16

Answer:

Yes, time play a factor in his decision, because after 3 years, option a is better, but after 9 years, option b is better.

Step-by-step explanation:

The following information is missing:

Mr. Nicholson accepts a job that pays an annual salary of $60,000. In his employment contract, he is given the option of choosing a) an annual  raise of $3,500 or b) an annual raise of 5% of his current salary.

The function that describes each situation is:

a) f(x) = 60,000 + 3,500*(x-1)

b) f(x) = 60,000*1.05^(x-1)

where x represents years and f(x) his salary.

Mr. Nicholson’s potential income for three years and nine years for each situation are:

a) f(3) = 60,000 + 3,500*(3-1) = $67,000

f(9) = 60,000 + 3,500*(9-1) = $88,000

b) f(3) = 60,000*1.05^(3-1) = $66,150

f(9) = 60,000*1.05^(9-1) = $88,647

Answer:

The cost of a bag of fruit is 45p

Step-by-step explanation:

Let w be the number of water bottles.

Let f be the number of bags of fruits.

"Two bottles of water and three small bags of fruit cost a total of £2.55"

2w + 3f = 2.55

"a bottle of water costs 15p more than a bag of fruit"

w = 0.15 + f

Substitute the second formula to the first and solve.

2w + 3f = 2.55

2(0.15 + f) + 3f = 2.55

0.3 + 2f + 3f = 2.55

0.3 + 5f = 2.55

5f = 2.55 - 0.30

5f = 2.25

f = 2.25 ÷ 5

f = 0.45

Substitute to the second formula again and solve for w.

w = 0.15 + 0.45

w = 0.6

Now verify:

2w + 3f = 2.55

2(0.6) + 3(0.45) = 2.55

1.2 + 1.35 = 2.55

2.55 = 2.55 (Correct)

Answer:

2.5

Step-by-step explanation:

I think you're missing a value because none of those work. 2.5 does

4*2.5 = 10

8 - 10 = -2

4 (-2) = -8

-8 + 20 = 12

Step-by-step explanation:

the formula for the area of a circle is A = pi r^2

Answer:

D

Step-by-step explanation:

you can just find the value of y and try some number of x

i.e. if x = 0, both of them will be 0

x = 1

G(x) result is -2

F(x) result is 1

x= -1

G(x) result will be 2

F(x) result is -1

so from these we can prove that G(x) is bigger graph than F(x) but flip vertically by y axis

Answer:

False

Step-by-step explanation:

A perpendicular line parallel to the y- axis has equation

x = c

where c is the value of the x- coordinates the line passes through.

The line passes through (1, 5) with x- coordinate 1, thus

x = 1 ← equation of perpendicular line

Answer: 277/12

Step-by-step explanation:

Use the order of operations or pemdas (parenthesis, exponents, multiplication, division, addition, subtraction) to solve this equation:

3 / 6^2 +7 x 4 - 5        

there are no parenthesis, so exponents

= 3 / 36 + 7 x 4 - 5            

now multiplication and division(from left to right)

= 3 / 36 + 7 x 4 - 5

= 1/12 + 28 - 5                  

addition and subtraction are next(it doesn't matter the order in this case):

1/12 + 23

=  1/12 + 276/12

= 277/12

The hypotenuse is √2 times as long as either leg of a 45-45-90 triangle

A triangle is a plane figure or polygon with three sides and three angles.

A Triangle has three vertices and the sum of the interior angles add up to 180°

Let the Triangle be ΔABC , such that

∠A + ∠B + ∠C = 180°

The area of the triangle = ( 1/2 ) x Length x Base

For a right angle triangle

From the Pythagoras Theorem , The hypotenuse² = base² + height²

if a² + b² = c² , it is a right triangle

if a² + b² < c² , it is an obtuse triangle

if a² + b² > c² , it is an acute triangle

Given data ,

Let the triangle be represented as ΔABC

Now , the measure of ∠ACB = measure of ∠BAC = 45°

And , the measure of ∠ABC = 90°

So , the triangle is a 45-45-90 triangle

Now , the measure of the sides be AB = BC = 1 unit

And , From the Pythagoras Theorem , The hypotenuse² = base² + height²

if a² + b² = c² , it is a right triangle

The measure of side AC ( hypotenuse ) = √ ( AB )² + ( BC )²

The measure of side AC ( hypotenuse ) = √ ( 1 + 1 )

The measure of side AC ( hypotenuse ) = √2 units

Hence , the measure of the hypotenuse of 45-45-90 triangle is √2 units

Answer: 46%

Step-by-step explanation:

Hi, to answer this question we have to write an equation:

The price of a movie ticket ten years ago (6.50) multiplied by a percentage in decimal form (x) is equal to 9.50.

6.50x = 9.50

Solving for x  

x =9.50/6.50

x = 1.46

Multiplying by 100 to obtain the percent form:

1.46 x 100 = 146%

Finally we have to subtract 100 to obtain the percent increase:

146-100 = 46%

Answer:

b= 3.5

s= 10.5

p=21

Step-by-step explanation:

b for brush

s for sketch book

p for paint set

b=1/3s

s= 1/2 p

b+s+p=37-2

1/3 s +s+2 s =35

1/3 s +s +2 s =35

10/3 s=35

s= 35*3/10

s= 10.5

b=1/3 s = 10.5/3 = 3.5

s= 1/2 p so p= 2s = 2( 10.5) = 21

10.5+3.5 + 21 = 35

The solution of given equation  x= -20

Step-by-step explanation:

Step(i):-

Given equation  - ( x /4) = 5

The sum of these is the following:

5500 ft + 1700 ft + 1600 ft + 5500 ft = 14,300 ft

Answer:

134 and 135

Because 269/2 is 134.5, so you know that one is 134 and the other is 135.

The page numbers are 134 and 135

Any positive or negative number without fractions or decimal places is known as an integer, often known as a "round number" or "whole number."

Given:

The left and right page numbers of an open book are two consecutive integers whose sum is 269.

Let two consecutive integers are n, n+1.

Then,

the sum of two consecutive integers is 269.

According to the question,

n + n + 1 = 269

2n + 1 = 269

2n = 268

n = 134

The integers are 134 and 135.

Therefore,  integers are 134 and 135.

Answer:

4 cm

Step-by-step explanation:

The figure is a parallelogram with area (A) calculated as

A = bh ( b is the base and h the perpendicular height )

Here A = 36 and b = 9 , thus

9h = 36 ( divide both sides by 9 )

h = 4 cm

Answer:

Step-by-step explanation:

considering the breadth of the shape as 5cm and length as 9cm...

now... for finding the height of the plane shape...

we need to use the formula for area of a trapezium...

so. area of a trapezium = 1/2 x height x sum of parallel sides

we are given area of trapezium = 36cm^2

SO SUBSTITUTING THE EQUATION...

36 = 1/2 x height x (9+9)

height = 4cm

Answer:

Option (d).

Step-by-step explanation:

Note: The base of log is missing in h(x).

Consider the given functions are

[tex]h(x)=\log_2x[/tex]

[tex]m(x)=\log_2(x+3)[/tex]

The function m(x) can be written as

[tex]m(x)=h(x+3)[/tex]           ...(1)

The translation is defined as

[tex]m(x)=h(x+a)+b[/tex]           .... (2)

Where, a is horizontal shift and b is vertical shift.

If a>0, then the graph shifts a units left and if a<0, then the graph shifts a units right.

If b>0, then the graph shifts b units up and if b<0, then the graph shifts b units down.

On comparing (1) and (2), we get

[tex]a=3,b=0[/tex]

Therefore, we have to translate each point of the graph of h(x) 3 units left to get the graph of m(x).

Hence, option (d) is correct.
