set up an equation to solve for x

2-x ≥ 0

subtract 2 from each side:

-x≥ -2

multiply both sides by -1 ( to make x positive) and reverse the sign

x≤2

Interest = $45.60, Rate = 2%, Time = 4 years<br> What’s the principal to the nearest cent

natita [175]

Answer:

$570

Step-by-step explanation:

I=PRT/100

I=$45.60,P=?,R=2%,T=4years

make P the subject of the formula

P=100I/RT

P=100x45.60/2x4

P=4560/8

P=$570

Type the correct answer in each box.

Mariulka [41]

Answer:

$(x-5)^2+(y+4)^2=100$

Step-by-step explanation:

step 1

Find the radius of the circle

we know that

The distance between the center and any point that lie on the circle is equal to the radius

we have the points

(5,-4) and (-3,2)

the formula to calculate the distance between two points is equal to

$d=\sqrt{(y2-y1)^{2}+(x2-x1)^{2}}$

substitute the values

$r=\sqrt{(2+4)^{2}+(-3-5)^{2}}$

$r=\sqrt{(6)^{2}+(-8)^{2}}$

$r=\sqrt{100}\ units$

$r=10\ units$

step 2

Find the equation of the circle

we know that

The equation of a circle in standard form is equal to

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

where

(h,k) is the center

r is the radius

we have

$(h,k)=(5,-4)\\r=10\ units$

substitute

$(x-5)^2+(y+4)^2=10^2$

$(x-5)^2+(y+4)^2=100$

Which expression can be used to find the area of the rectangle shown on the coordinate plane?

Naily [24]

Answer:

8 * 7

Explanation:

When you count the squares along the area, you will find that the base is 8 units, and the height is 7 units. The area of a square is equal to base * height, so the correct answer is 8 * 7.

Help I be trying so but can figure out the answer

Sphinxa [80]

Answer:

Step-by-step explanation:

Surface of the earth =3959×3.14

=12,437.565

if 20%is suitable so we multiply it by the surface

12,437.565×0.2=2,487.513 per people

2,487.513/7,700,00,00

So I think it will be the closest to b
