Answer:

The statement is false

Step-by-step explanation:

we know that

tan(x)=\frac{sin(x)}{cos(x)}

The tangent function will be positive when the sine function and the cosine function have the same sign

so

In the first quadrant the tangent function is positive

In the third quadrant the tangent function is positive

so

The statement is false

I believe the correct answer would be false. The tangents are positive in quadrant I and in III. A tangent in a certain quadrant is said to be positive if all 3 trigonometric function, namely sine, cosine and tangent, are positive. Hope this answers the question. Have a nice day.

What is the equation of the line that passes through the point (-2, 0) and has
garik1379 [7]

Answer:

y = 2x + 4

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Here m = 2 , then

y = 2x + c ← is the partial equation

To find c substitute (- 2, 0 ) into the partial equation

0 = - 4 + c ⇒ c = 0 + 4 = 4

y = 2x + 4 ← equation of line

AEFI Is dilated by a scale factor of with the center of dilation at point F. Then, it is reflected over line a to create AHFG. B
Pavel [41]

Answer:

C

Step-by-step explanation:

It's stated that EFI is dilated by a scale factor of 1/3.

Dilating gives the following

FH = 1/3×FE

FG = 1/3×FI

HG = 1/3×EI

Sense ΔEFI is reflected over a line FG/FH = (1/3×FI)/(1/3×FE) = FI/FE

Notice that the following shows triangle similarity, meaning ΔEFI ~ ΔHFG.

The only answer choice that shows this would be FE/3 = FH, FI/3 = FH, and

EI/3 =HG ΔEFI ~ ΔHFG.
