Answer:

y=6

Step-by-step explanation:

The equation of the line with slope 2 is y=2x+b, b is a constant which should be determined. The line passes via through points (1, 2) and (3,y)

(1, 2): 2=2+b --> b=0

So, the equation of the line is y=2x. Now, when x=3, y=6. So the line y=2x passes through points (1, 2) and (3, 6). (3,y)=(3, 6).

How do I verify #15 using fundamental trig identities?

expeople1 [14]

We start with the more complicated side which is the left side, and show that, on using some trigonometric identities, we will get the term on the right side .

$\frac{sin \theta + tan \theta}{1+cos \theta}$

Using Quotient identity for tangent function, we will get

$\frac{sin \theta+ \frac{sin \theta}{cos \theta}}{1+cos \theta}$

$\frac{sin \theta cos \theta + sin \theta}{cos \theta(1+cos \theta)}$

Taking out sine function from the numerator

$=\frac{sin \theta(1+cos \theta)}{cos \theta(1+cos \theta)}$

Cancelling the common term of numerator and denominator

$=\frac{sin \theta}{cos \theta} = tan \theta$

Which of the following is equivalent to cos x?

Otrada [13]

ANSWER

D) sin Y

EXPLANATION

The given triangle is a right triangle.

This implies that that:

$x + y = 90 \degree$

Then we have

$y= 90 - x$

Recall that

$\cos(x) = \sin(90 - x)$

But

$90 - x = y$

When we do the substitution, we get,

$\cos(x) = \sin(y)$

Therefore cos(x) is a equivalent to sin(y).

The correct answer is D.

After driving 152 km, 4/5 of a trip is completed. How long is the total trip? How many more kilometers must be driven to compl

nikitadnepr [17]

Answer:

1. Total Trip Distance = 190 kilometers

2. To complete the trip, 38 more kilometers left

Step-by-step explanation:

Let total trip be x kilometers.

So we can say

<em>"152 is $\frac{4}{5}$ of total" --- this into equation is:</em>

$152=\frac{4}{5}x\\x=\frac{152}{\frac{4}{5}}\\x=190$

Total trip is 190 km.

Since already driven 152, to complete 190, you have to drive $190-152=38$ kilometers more.

So, 38 more kilometers to complete the trip.
