Answer:

Option D. A student who studies 0 hours can expect to score about a 60 on the test

Step-by-step explanation:

we know that

The y-intercept is the value of the y-coordinate when the value of the x-coordinate is equal to zero

In this problem

The x-coordinate represent the hours spent studying

The y-coordinate represent the Test score

For x=0, y=60

That means

A student who studies 0 hours can expect to score about a 60 on the test

Solve for q. √3q + 2 = √5

34kurt

Answer:

$q = 0.0186$

Step-by-step explanation:

To solve for q, we initially place everything with the term q to one side of the equality, and everything without the term q to the other side of the equality.

$\sqrt{3q} + 2 = \sqrt{5}$

$\sqrt{3q} = \sqrt{5} - 2$

We find the square of both sides of the equation. So

$(\sqrt{3q})^{2} = (\sqrt{5} - 2)^{2}$

$3q = 0.0557$

$q = \frac{0.0557}{3}$

$q = 0.0186$

Prove this trigonometric identity sin 3x/sin x - cos 3x/cos x =2

Sveta_85 [38]

Step-by-step explanation:

LHS= sin 3x/sin x - cos 3x/cosx

Taking LCM,

=sin3xcosx- cos3xsinx

sinxcosx

=sin(3x-x)

sinxcosx

= 2sin2x

2sinxcosx

= 2sin2x

sin2x

= RHS.

Proved.

You are in a bike race. When you get to the first checkpoint, you are $\frac{2}{5}$

Black_prince [1.1K]

Answer:

The distance from the star to the second checkpoint is 4 miles

Step-by-step explanation:

The complete question in the attached figure

we know that

When you get to the second checkpoint, you are 1/4 of the distance to the finish

The distance from the star to the second checkpoint is equal to the total distance multiplied by 1/4

The total distance is 40 miles ( see the attached figure)

The distance from the star to the second checkpoint is

$\frac{1}{4}(40)=10\ miles$

Find out the distance from the start to the first checkpoint

Multiply the distance from the star to the second checkpoint by 2/5

$\frac{2}{5}(10)=4\ miles$
