Answer:

Option (b) is correct.

The measure of angle y is 39°

Step-by-step explanation:

Given : A right angled triangle with some measurements.

We have to find the value of y.

Consider the given triangle,

Using trigonometric ratios,

We know tangent is the ratio of perpendicular to its base.

Mathematically written as

\tan\theta=\frac{Perpendicular}{base}

So, for given triangle, \theta=y

and for y, perpendicular is 8 and base is 10

Substitue, we have,

\tan y=\frac{8}{10}

Simplify, we have,

\tan y=\frac{4}{5}

Taking inverse of tan both side, we have,

\tan^{-1}(\tan y)=\tan^{-1}(\frac{4}{5})

y=\tan^{-1}(\frac{8}{10})

Simplify , we have,

y=38.65^{\circ}

Thus, the measure of angle y is 39°

<h2>Answer: </h2>

We know that,

  • Length of arc = 2πrθ/360

Length of arc = 2 × 3.14 × 6 × 45/360

Length of arc = 6.28 × 3/4

= 18.84/4

= 4.71units.

In the x-y plane, what is the y- intercept of the graph of the equation y=6 (x-1/2) (x+3)
Ivenika [448]

The y-intercept on the x-y plane is (0, -9).

<h3 /><h3>How to get the y-intercept?</h3>

To get the y-intercept we just need to evaluate in x = 0.

Here we have:

y = 6*(x - 1/2)*(x + 3)

Evaluating the given equation in x = 0 we get:

y = 6*(0 - 1/2)*(0 + 3) = -9

Then the y-intercept on the x-y plane is (0, -9).

Determine what type of model bet fits the given situation: Every day, half a bacteria population dies. A. Linear B.quadratic C.
makvit [3.9K]

Answer:

Exponential

Step-by-step explanation:

<em>Starter:</em>

According to the title:

"Every day, half a bacteria population dies."

Exponential: y = ab^x ( b > 0 , b ≠ 1)

So the answer is C.

<em>Calculations:</em>

An exponential model is of the form y = a • b^t.

If you start with population of 500 million bacteria

t = 0

so 500 million = a • b^0 = a

Since every day half the population dies then in 1 day population will be 250 million

so a = 500 million, y = 250 million and t = 1

250 million = 500 million • b^1

b = 0.5

Therefore your equation would be

y = 500 million (or whatever the pop) • 0.5^t

Where t = number of days

This could also be written in exponential form ( e = 2.73)
