Step-by-step explanation:

it's something in algebra i don't remember but basically the top number (12) has the x on the bottom which is multiplication and the bottom number (8) has addition so those tell u how ur supposed to get those numbers

so basically u need to find two numbers that add up to 8 and multiply to 12 so the factors are 6 and 2 because 6 • 2 is 12 and 6 + 2 = 8. hope this helps

If r = x, y, z and r0 = x0, y0, z0 , describe the set of all points (x, y, z) such that |r − r0| = 5.

Artist 52 [7]

We are concern about the vector (x-x0, y-y0, z-z0) equaling to 5.

This happens when √(x-x0)^2 + (y-y0)^2 + (z-z0)^2 = 5

Square both side:

(x-x0)^2 + (y-y0)^2 + (z-z0)^2 = 25 , a sphere

Which you will recognize as a circle of radius one centered at (x0, y0, z0)

Please help me i need it right now please

Given:

The rate of interest on three accounts are 7%, 8%, 9%.

She has twice as much money invested at 8% as she does in 7%.

She has three times as much at 9% as she has at 7%.

Total interest for the year is $150.

To find:

Amount invested on each rate.

Solution:

Let x be the amount invested at 7%. Then,

The amount invested at 8% = 2x

The amount invested at 9% = 3x

Total interest for the year is $150.

$x\times \dfrac{7}{100}+2x\times \dfrac{8}{100}+3x\times \dfrac{9}{100}=150$

Multiply both sides by 100.

$7x+16x+27x=15000$

$50x=15000$

Divide both sides by 50.

$x=\dfrac{15000}{50}$

$x=300$

The amount invested at 7% is $300$ .

The amount invested at 8% is

$2(300)=600$

The amount invested at 9% is

$3(300)=900$

Thus, the stockbroker invested $300 at 7%, $600 at 8%, and $900 at 9%.

Calculate the angle to the nearest degree: csc (x) = 1.0353

sammy [17]

Answer:

$75^{\circ}$

Step-by-step explanation:

Given: $\csc (x) = 1.0353$

To find: angle to the nearest degree

Solution:

A triangle is a polygon that has three sides, three angles ,and three vertices.

Trigonometry explains the relationship between the sides and angles of the triangle.

The angle can be expressed in two forms: degrees or radians.

$\csc (x) = 1.0353\\x=74.995\approx 75^{\circ}$
