Answer:

0.25c

Step-by-step explanation:

.25 is the decimal form of 25%. .25 * c is how you get the amount you don't have to pay on this item.

For example:

.25 * 10= 2.5

10-2.5=$7.5

Find the equation of the line through point (2,2) and parallel to y=x+4. Use a forward slash (i.e.”/“) for fractions (e.g. 1/2 f

aleksandr82 [10.1K]

Answer:

The equation of the line is, y = x

Step-by-step explanation:

The constraints of the required linear equation are;

The point through which the line passes = (2, 2)

The line to which the required line is parallel = y = x + 4

Two lines are parallel if they have the same slope, therefore, we have;

The slope of the line, y = x + 4 is m = 1

Therefore, the slope of the required line = 1

The equation of the required lime in point and slope form becomes;

y - 2 = 1 × (x - 2)

∴ y = x - 2 + 2 = x

The equation of the required line is therefore, y = x

X^4 - x^2 - 2x -1 . solve

Alchen [17]

Answer:

X⁴–X²–2X –1=0

(X²+X+1)(X²–X–1)=0

$x = - \frac{1 - i\sqrt{3} }{2} \\ x = - \frac{ 1 + i \sqrt{3} }{2}$

$x = \frac{1 + \sqrt{5} }{2} \\ x = \frac{1 - \sqrt{5} }{2}$

I hope I helped you^_^

PQR has medians QM and PM that intersect at Z. If ZM = 4, find QZ and QM.

erastova [34]

Answer:

value of QZ = 8 units and QM = 12 units.

Step-by-step explanation:

Given: In triangle PQR has medians QM and PN that intersect at Z.

If ZM = 4 units.

In the figure given below; second median divided the two triangles formed by the first median in the ratio 2:1.

We have to find the value of QZ and QM;

QZ:ZM = 2: 1

⇒ $\frac{QZ}{ZM} = \frac{2}{1}$

Substitute the value of ZM =4 units and solve for QZ;

$\frac{QZ}{4} = \frac{2}{1}$

Multiply both sides by 4 we get;

$QZ = 2 \times 4 = 8 units$

Now, calculate QM;

QM = QZ+ZM = 8 + 4 = 12 units.

Therefore, the value of QZ and QM are; 8 units and 12 units

- Macy has a circular pool with a diameter of 18 feet. If she swims

nikklg [1K]

Calculating water volume of a pool requires a number of preliminary the measurements together to determine the complete perimeter, though what is really necessary is to measure only one side of square pool, then multiply by 4. So, a round pool with a 20-foot diameter has a circumference of 3.14 x
