Answer:

L * W = area

L * W = 190

L + 1 = 2W

Therefore, L = 2W - 1

The easiest way to do this is to find the factors, and then see what fits.

Step-by-step explanation:

Factors of 190 = {190,1}, {95,2}, {5,38}, {19,10}

In which of these pairs is one number "twice as much less one" than the other?  

The solution is 19,10. 19*10 = 190 square feet. The length (19) is twice the width (10) minus one.

Explain the difference between using the sine ratio to solve for a missing angle in a right triangle versus using the cosecant r
oksano4ka [1.4K]

Answer:

The sine ratio is the ratio between the opposite side over hypotenuse. The cosecant ratio is the ratio between the hypotenuse over the opposite side, therefore cosecant is the reciprocal of sine.

To find a missing angle using sine, you would need to use the inverse of sine. For example,  if the sine was  \frac{30}{40}, to find the angle you would need to find sin⁻¹ of  \frac{30}{40} which is x =  sin⁻¹ (0.75). Therefore x equals approximately 49°.

Given the graph of a function below, Determine the interval in which the function has a negative value.
Serggg [28]

Answer:

B

Step-by-step explanation:

The "value" of a function is the y-value.

Since we want negative y values, we look at "WHERE" the function is "UNDER" the y-axis.

Looking closely, it looks that function (the dip) is from x = -1 to x = 3

Hence, the function is negative at the interval  -1 ≤ x ≤ 3

B is correct.
