Answer:

(6,3)

Step-by-step explanation:

Answer:

Step-by-step explanation:

let (x,y) be any point on the locus.

Then

[tex]\sqrt{(x-1)^2+(y-6)^2} =7\\or\\(x-1)^2+(y-6)^2=49\\which ~is~a~circle.[/tex]

Answer:

2.25%

Step-by-step explanation:

I = Prt

Given:

I = 540

P = 8000

t = 3

Solve for r:

I = Prt

r = I/(Pt)

r = 540/(8000 * 3)

r = 540/24000

r = 0.0225

Rate in percentage form:

0.0225 * 100 = 2.25%

Hey there,

The equation is already written in circle equation form but if needed, here is what it will look like when it isn't simplified.

(x - (-3))² + (y - (-3/2))² = 2²

With this, the circle has a center at (-3, -3/2) and a radius of 2.

Best of Luck!

Step-by-step explanation:

Hey there!

Given;

The equation of a circle is:(X+3)² + (y+3/2)² = 4.

Comparing the equation with (x-h)²+(y-k)² = r², we get;

Centre (h,k) = (-3,-3/2)

Radius (r) = 2 units.

Hope it helps!

Step-by-step explanation:

Answer:

35 feet

Step-by-step explanation:

The problem is a right angle triangle problem and we have to solve it using pythagoras theorem

Let the length of the wire be x

So;

x^2 = 34^2 + 8^2

x = √34^2 + 8^2

x = 35 feet

Answer:

_ = 48

Step-by-step explanation:

7 (3 + 5) = 8 + _

7 x 3 + 7 x 5 = 8 + _

21 + 35 = 8 + _

56 = 8 + _

_ = 56 - 8

_ = 48

Hope that helps!

Answer: x = 48

PEMDAS

7  (3 + 5) = 8 + x

7  (8) = 8 + x

56 = 8 + x

isolate x by subtracting 8

48 = x

Hello There!

I had made a graph with the given points plotted

If you were to draw a line straight through the middle of the points

most of the points would be near the line therefore the correlation is strong

The relationship is also positive because the points are going from left to right up

So we can conclude that the answer would be D

X = -4

Step-by-step explanation:

91x + 637 =273

First subtract 637 from both sides: 91x = -364

Then, divide both sides by 91 to get X by itself: X = -4

Answer: Micah

Step-by-step explanation:

Given

Raven told Perimeter of the swimming pool is [tex]35\ ft[/tex]

Micah said Perimeter is [tex]24\ ft[/tex]

The actual dimension of the swimming pool is [tex]5\ ft\times 7\ ft[/tex]

Perimeter is given by  [tex]2(l+w)[/tex]

Using this, the perimeter is

[tex]\Rightarrow P=2(5+7)\\\Rightarrow P=2\times 12=24\ ft[/tex]

[tex]\therefore[/tex] Micah statement is correct.

Answer:

There are 4 prime numbers.

Step-by-step explanation:

The prime numbers are: 151, 157, 163, 167

You just need to know what numbers are prime numbers.

Answer:

4 prime numbers

Step-by-step explanation

A prime numbers is a natural number greater than 1 that is not a product of two smaller natural numbers. For example, 5 is a prime number because it is multiplied by 1 and itself. On the contrary, 4 is not a prime number because it is multiplied by 2. Remeber 1 is not a prime number because it has only 1 factor and prime numbers have exactly 2 factors. Therfore the prime numbers in between 150 and 170 are.... 151, 157,163, and 167.

             The 4 prime numbers between 150 and 170 are:

                                     151, 157, 163, 167

Answer:

3,456 m²

Step-by-step explanation:

i just took the test :)

The surface area of the given Square pyramid is 3456 square meters.

The area or region that an object’s surface occupies is known as its surface area. Volume, on the other hand, refers to how much room an object has. There are numerous shapes and dimensions in geometry, including spheres, cubes, cuboids, cones, cylinders, etc. Each form has its own volume and surface area.

Given, a square pyramid with a base side of 36m and a slant height of 30m.

From the general formula of the surface area of the square pyramid,

Surface area = area of base + 4* area of triangle

Surface area = 36*36 + 4 * 1/2*36 * 30

Surface area = 3456 m²

therefore, the surface area of the given Square pyramid is 3456 square meters.
