Answer:

2π/7

Step-by-step explanation:

A cosine wave is:

y = A cos(2π/T x + B) + C

where A is the amplitude,

T is the period,

B is the horizontal shift,

and C is the vertical shift.

In this case:

7 = 2π/T

T = 2π/7

Answer:

The period the la function is with the formula that will be explained below

Step-by-step explanation:

The period is calculated with this formula:

2 π

The absolute value is the distance between a number and zero, therefore the distance between zero and 7 is therefore 7; therefore we finally have:

Periodo:

2 π

Identify the converse of the following conditional: If a point is in the first quadrant, then its coordinates are positive.

Vadim26 [7]

Answer: If the coordinates are positive, then the point is in the first quadrant

The converse has us swap the antecedent (first part) and the conclusion (second part) of the conditional. In symbolic notation we would have

Original: If P, then Q
Converse: If Q, then P

The M virus has a diameter of 5 x 10^-7meters, while the P virus measures about 2 x 10^-8meters in diameter. A) is the M virus o

Fynjy0 [20]

Answer:

(A) The M virus is larger than the P virus in diameter

(B) Diameter of virus M is 25 times the diameter of virus P

Step-by-step explanation:

Notice that the values given are in the so called "scientific notation", and which involves in this case negative exponents for the multiplier 10.

So we can write these values in decimal form for easier comparison of which one is he largest one:

Diameter of M virus = $5\,*\,10^{-7}\,m = 0.0000005\,\,m$
