Answer: C: (x - 4)² + (y+2)² = 25

Step-by-step explanation:

The formula for a circle is: (x - h)^2 + (y - k)^2 = r^2

Using this, the formula should be:

C: (x - 4)² + (y+2)² = 25

Step-by-step explanation:

Bond A and C the annual interest rate is 1.126%.

Bond X and Y the annual interest rate is 1.25%.

The interest rate on a credit card is the cost of borrowing money. Interest rates on credit cards are often provided as an annual rate. This is known as the annual percentage rate (APR). You can avoid paying interest on purchases on most cards if you pay your amount in full each month by the due date.

The formula for Bond Coupon Rate

Bond Coupon Rate = Bond's current yield / 100

For bond A and C coupon rate is 7.5%.

For X and Y coupon rate is 8.4%.

Now, Annual Interest Rate

= Bond coupon rate x Bond's Face value

For bond A and C the annual interest rate

= 7.5% of $15

= $1.125

For bond X and Y the annual interest rate

= 8.4% of $15

= $1.26

3x 10^4 NOT NEGATIVE! POSITIVE

Answer:

it's 10

Step-by-step explanation:

A ratio of 2:5 means it is probably counting by 5s. Since 5 X 5 equals 25, 2 X 5 equals 10. since ethe larger polygon is 25, this means the number can't be bigger than 25 so it is counting by fives.

Answer:

384 cm

Step-by-step explanation:

Perimeter is the sum of all external sides. (do not mix this up with area. Perimeter is the easy one) :)

There are 4 external sides.

Top = bottom = 132 cm

Left = Right = 60 cm

Add all 4 sides:

2(132) + 2(60)

264 + 120 = 384 cm

Answer:

A

a notebook costs $2.50

a poem costs $1.50

B

he can buy 3 pens (and correspondingly 9 notebooks)

Step-by-step explanation:

x = price of 1 notebook

y = price of 1 pen

4x + 3y = 14.5

5x + 6y = 21.5

let's multiply the first equating by -2 and then add both equations

-8x - 6y = -29

5x + 6y = 21.5

----------------------

-3x 0 = -7.5

x = 2.5 = $2.50

4×2.5 + 3y = 14.5

10 + 3y = 14.5

3y = 4.5

y = 1.5 = $1.50

p = number of pens

n = number of notebooks

n = 3p

p×1.5 + n×2.5 = 27

p×1.5 + 3p×2.5 = 27

(1.5 + 7.5)p = 27

9p = 27

p = 3

Since a force of 37 N is applied to the spring, the spring stretches by 9.74 cm

To answer the question, we need to know Hooke's law.

This states that the force, F on a stretched spring is directly proportional to its extension, x.

So, F ∝ x

Mathematically, F = kx where k = spring constant

Making x subject of the formula, we have

x = F/k

Given that F = 37 N and k = 380 N/m, we have

x = F/k

x = 37 N/380 N/m

x = 0.0974 m

x = 9.74 cm

So, the spring stretches by 9.74 cm

we cant add these matrices by the first martix had 2 colums and 2 rows.

The second has 1 column and 2 rows.

Answer:

-2

Step-by-step explanation:

(-3x/2) - 3 = 3

add 3 to both sides

(-3x/2) = 3

multiply both sides by 2

-3x = 6

divide both sides by -3

x= -2

The height of the balloon is given as h(t) = -16t² + 40t + 12 at 2 seconds, the height is 28 feet

An equation is an expression that shows the relationship between two or more numbers and variables.

Let h represent the height of the water balloon after t minutes, hence:

h(t) = -16t² + vt + h₀

Where h₀ is the initial height = 12 feet and v is the initial velocity, hence:

h(t) = -16t² + vt + 12

The height of 37 feet after 1.25 seconds, hence:

37 = -16(1.25)² + v(1.25) + 12

v = 40 m/s

h(t) = -16t² + 40t + 12

After 2 seconds:

h(t) = -16(2)² + 40(2) + 12

h(2) = 28 feet

The height of the balloon at 2 seconds is 28 feet
