Answer:

$16,557

Step-by-step explanation:

The computation of the amount after four years is shown below:

As we know that

Future value = Present value × (1 + rate of interest)^number of years

= £15,000 × (1 + 2.5%)^4

= £15,000 × 1.025^4

PLEASE HURRY Fill in the blank:

makkiz [27]

Answer:

This is slope-intercept form: y = (-3/4)x + 3

The slope is: -3/4

The y-intercept is: 3

Step-by-step explanation:

3x + 4y - 12 = 0

Isolate y

3x - 3x + 4y -12 + 12 = -3x + 12

Simplify

4y = -3x + 12

Divide 4 on each side to get y by itself

4y/4 = -3x/4 + 12/4

Simplify

y = (-3/4)x + 3

This is slope-intercept form: y = (-3/4)x + 3

The slope is: -3/4

The y-intercept is: 3

What is the equation of the circle whose center and radius are given.

muminat

Hello!

The equation for a circle is

$(x - h)^{2} + ( y - k)^{2} = r^{2}$

(h,k) is the center
r is the radius

Put in the values you know

$(x - 7)^{2} + ( y + 3)^{2} = 7^{2}$

Simplify

$(x - 7)^{2} + ( y + 3)^{2} = 49$

The equation is $(x - 7)^{2} + ( y + 3)^{2} = 49$

Hope this helps!
