It would be 200cm, because 100 cm is 1 meter, and 1.25 would be 125 cm.  So if you subtracts 125 from 325, you get 200 cm.

Which of the following is a quadratic function?
sp2606 [1]

A is the answer, because the highest exponent is 2.

<u>quadratic</u>

A's expression foiled would be 2x^2 + x - 6

B's expression foiled would be 3x - 12, where the exponent on x is only 1.

D's expression foiled would be x^3 - x^2 - 12x, where the exponent on x is 3.

A car travels 87 miles north and 114 miles west. what is the magnitude of the cars resultant vector
anyanavicka [17]

The magnitude of the resultant vector is 27 miles

<h3>How to determine the vector magnitude</h3>

Resultant vector = Distance of A - Distance of B

This is so because of the opposite direction of the car's movement

A = 87 miles

B = 114 miles

Resultant vector = 114 - 87

Resultant vector = 27 miles

Thus, the magnitude of the resultant vector is 27 miles

Answer:

x=27\ units

Step-by-step explanation:

we know that

Triangles BDR and QDC are similar, because QC and BR are parallel lines

If two figures are similar, then the ratio of its corresponding sides is equal and is called the scale factor

In this problem

\frac{QD}{BD} =\frac{DC}{RD}

substitute the values

\frac{39}{39+26} =\frac{x}{x+18}

\frac{39}{65} =\frac{x}{x+18}

65x=39(x+18)

65x-39x=702

26x=702

x=702/26

x=27\ units
